Straight from the V*Star 1100 manual:

guidelines:
From Metzeler: Fitment for Classic,
Silverado - below are the recommended psi front and rear:

| In many
cases Metzeler provides you, the consumer, with optional tire
choices for your motorcycle. The data below is designed to
callout a optional suggested fitment or upgrade for your
application. To learn more about these please click on the box
to the left marked important upgrade info To see the suggested
tire pressure range please click on the box to the left marked
recommended tire pressures. |
From Metzler:
http://www.us.metzelermoto.com/web/products/tire_pressures/default.page
Note: Re below info
- appears the ME880 Marathon must fall in the
Alpha ME880 (MH, MT, MU tires) grouping, given the Max pressure
indicated on the sidewall is 40 psi, based on any ME880 Marathon have
have fitted on my rides.
Tire Pressure
Always inflate tires to the correct pressure as indicated in the
owner's manual. However
Metzeler North America has found the air pressure suggestions listed
below will improve mileage and customer satisfaction especially if a
emphasis is placed on running the air pressure towards the maximum as
stated on the sidewall. Check
cold tire pressures frequently. Correct tire pressure is crucial for
safe handling. Over inflation may impair ride comfort and reduce the
contact patch between the tire and driving surface of the tires.
Insufficient air pressure will result in poor handling and cause a
tendency for the motorcycle to "wander". In addition, improper and
insufficient tire will cause accelerated tire wear, increased fuel
consumption, less control and the possibilities for tire failure to due
an overload/under inflated operating situation.

Flat Tire Prevention / Repair
(updated 06/05/10)
On Repairing Tubeless Tires:
This is from Dunlop's site:
(complements of LowPhat)
Dunlop recommends only permanent repairs performed from the inside of
the tire, using a combination patch/plug method. Never attempt a repair
from the outside, or inject a sealant, or simply use an inner tube, a
patch or a plug as a substitute for a proper repair.
Only a qualified tire repair shop or motorcycle tire dealer should
perform repairs. Inspection of the tire and adequacy of repair becomes
the responsibility of the person actually performing the repair and
Dunlop does not warrant the results of a repair in any way. Combination
patch/plug repair kits for use by the repair shop or dealer are
available with accompanying instructions from companies such as:
Remarco Inc.
200 Paris Ave.
Northvale, NJ 07647
(201) 768-8100
Technical Rubber Co.
P.O. Box 486
Johnstown, OH 43031
(740) 967-9015
Tip-Top/Moto Combi Kit
Tech Uni-Seal® Repair Kit (Also has been marketed by Honda, Kawasaki,
and Yamaha with their own part numbers.)
NOTE: There may be suitable repair kits and materials provided by
manufacturers other than those listed above.
Before any repair should be attempted, however, a tire must be removed
from the wheel and thoroughly inspected. The following are minimum
guidelines for the repairer:
Tires should not be repaired if any of the following conditions exist:
1. A tire has been previously injected with a sealant/balancer.
2. The puncture is larger than 6mm (1/4") in diameter.
3. The puncture is not perpendicular to the carcass.
4. The puncture is in the tire sidewall.
5. Separation of plies, tread separation, separation of any other
components.
6. Cut or broken ply cords.
7. Broken or damaged bead wires.
8. Cut or damaged chafers (bead area).
9. Deterioration of the carcass inside the tire due to "run flat" or
underinflation.
10. Cracks or other damage to the integrity of the inner liner.
11. Excessive wear - tire should have at least 1/32 of an inch of tread
depth, excluding tread wear indicators.
12. Cracks in sidewall or tread.
13. Impact breaks, cuts, snags or gouges that penetrate the surface.
NOTE:
1. There should be no more than one repair in any quarter of the tire
and no more than two repairs per tire.
2. The wheel itself must be in good condition. Any cracked or bent
wheel, however slightly, may allow the loss of air and cause subsequent
deflation of the tire.
3. Following repair, the valve assembly should be replaced and the
tire/wheel rebalanced.
4. Speed should not exceed 50 mph for the first 24 hours after tire
repair and the repaired tire should never be used at speeds over 80 mph.
The repairer is solely responsible for instructing the motorcyclist as
to the restrictions to be placed on tire use following repair.
In summary, NO form of temporary repair should be attempted. Motorcycle
tire repairs leave no room for error and any doubt as to inspection or
adequacy of repair should be resolved by discarding the tire.
Be sure to consult our Motorcycle Tire Limited Warranty, Care and
Maintenance brochure for additional information regarding the use of
Dunlop tires. Seek a qualified motorcycle tire repair center for more
details. NEVER ATTEMPT TO REPAIR A DAMAGED TIRE WITHOUT THE AIDE OF AN
EXPERIENCED TIRE MECHANIC.

Don't Be Fooled - Measure Your Tire
Life/Handling
(updated 8/2/06)
From DaddoCFL:
When the new rubber goes on the
bike, here is what you will experience:
Wow, these tires really make this bike handle better then those “old” tires.
When you change tires again, you will say exactly the same thing about the
Dunlops over the Metzlers.
This is a common experience that fools a lot of riders into thinking that
whatever “new” tires went on the bike are “so much better then crappy brand
that I had on there before”. This is pure delusion as ANY new tire set will
perform better then ANY worn tires.
So, do it the right way:
Meltzer's vs. Dunlop
When you get the Meltzer's on
your bike, record the mileage and the date. I have no clue as to how many
miles you do a year, but the information will be useful to you.
When rear tire time rolls around again, get the Dunlop rear (the front will
be just less then half worn) keep the same data on the Dunlop as you did
with the Metzler and you will understand the reason for my recommendations.

Types of Tires & Mixing Types
(updated 1/15/06)
Daddo (DaddoCFL) :
I don’t believe that mixing
different brands of tires on a bike, in most riding conditions, is going to
be an issue. This is particularly true on a Cruiser like a V-Star. As long
as you stay within the parameters set by the manufacturer for tire sizing
and inflation pressure, you are good to go. I have ridden Dunlop (f) &
Pirelli and Avon (r), Metzler (f) & Dunlop, and Pirelli (r), with no ill
effects – Incidentally, I have come back to Dunlop 404’s front and rear for
good!
What you can’t (safely) do is to mix Bias Ply Tires and Radial Ply Tires on
the same bike. This becomes an issue when you want to switch to a different
brand of tire, to replace a worn rear tread for example. If the particular
tire you want is produced as a Radial Ply, and you have a Bias Ply tire on
the front, then you are confronted with a decision. Either pick a different
replacement tire, or plan on replacing both front and rear.
Bias and Radial ply tires have completely different dynamic properties. When
they are leaned into a corner, the sidewalls and tread will deflect
differently. This will create different cornering forces (which will make
them want to make the turn at a slightly different rate). Bias and Radial
ply tires also have very different damping characteristics which can make
travel on a “textured” road kind of interesting.
Momma Yamma specifies Bias Ply tires for a reason. The frame, steering
geometry and suspension of this particular bike is set up for the handling
characteristics of a Bias Ply cruiser tire. There are of course those
individuals who are running Radial Ply tires on their V-Stars. That is fine,
and they most likely don’t see any negative differences in the ride as long
as there are Radials on the front and rear. I am just more comfortable in
riding on the rubber that the design engineers have determined to be the
best combination of handling performance and safety for my bike.
The common "wisdom" (perhaps old
wives tale) out there is that you can’t have radial tires with a tube on a
wheel due to the fact that because of the way that Radial tires flex in
motion and deflect while cornering, the increased friction will abrade and
finally cause the tube to fail.
This does not mean that you can’t do it as a whole load of riders equip
their bikes with a tube/radial combination. I’m kind of thinking that this
is in line with the same advice that used to be given to sports car (wire
wheel) owners back in the 60’s and early 70’s when radials were becoming
popular in this country.
When you run that combination on a car tire, with considerably heavier
loading for 35,000 to 50,000 miles, there could be an issue. A motorcycle,
with much stickier and softer road tread will usually say bye, bye in well
under 20,000 miles. I would seriously doubt that the same problem exists.
Maybe there are warnings from MC tire manufacturers out there about this
issue, but I have never seen them anywhere. I would think that in this
litigious society, any manufacturer would be insane not to post a
conspicuous warning if they seriously thought a problem existed.
If you are still uncomfortable with the possibility of a problem, most
larger Harley dealers will have a source for sealing spoked wheels for
running without a tube. And no, please don’t try to seal it yourself with
silicone sealant like those glory seeking custom builders on TV.
If you do ultimately run tubeless, I would still go with a bias ply tire and
the bike is matched to that type or response and performance.
The most important label on a
tire is the sizing designation, which in this case reads "110/90H 18” This
label indicates section width (110mm), aspect ratio (90 percent), speed
rating (H - Up to 130 mph or 210 km/h), and wheel diameter (18 inches).
In the case of a Radial tire, the construction designation (R) would follow
the Aspect Ratio

Kent_in_KC and his "The Great White Wall
Experiment " Thread:
http://forums.delphiforums.com/yamaha1100/messages?msg=40287.1
"My conclusions are that: 1) painted
whitewalls are 'okay' but not as good as factory whitewalls. Reason,
the paint 'checks' and can be scuffed off fairly easily. Now,
factory whitewalls can be damaged too, so maybe that's not such a
big difference.
With painted WWs you can figure on repainting them or at least
touchig them up at least once a season. While you can make a wheel
stand to simplify the initial off-bike job, touchups are a pain
unless you want to pul the wheels and, hey, that's a pain too now
ain't it?
My other thing to report is that the Michelin LXR does in fact seem
to help keep the WWs clean and to make them easier to clean. I put
it on one tire and compared it to the untreated tire, noticeable
difference.
So, for me, my next rubber will be a set of Metzler WWs which I will
treat with the LXR."

Oversized
(updated0624/08)
Metzler 200/70-15 fits on
Rear! - But . . . (Two views)
Green Snake (fordjake): Just reinstalled my rear tire
with the Meltzer 200/70-15 and I love it. Gave me about 1/2 inch wider and
no clearance problems. This tire is now about 2 millimeters taller then
stock not a big difference. Just wanted to post this for everyone's
knowledge.
wekenav8r: had thought
about doing this too. There are a few threads about it on Baron's tech
forums. They advise against doing this. They say this tire is just too
wide for the Vstar rim, and wouldn't be safe, even though the tire
manufacturer says it's OK. I'm still torn on this one. In addition to the
safety factor, they say some bikes come with the sub-frame offset which can
cause clearance problems. Good luck with it, I hope it works well for you.
Sometimes it's hard to cut through the BS, and know what works and what
doesn't. Personally I would think it would be fine if the tire maker says
so.
More - Against Doing It:
From Stuwindsurf, posted 6/24/08
Forgive me for stirring up and
old thread but after reading conflicting opinions about the 200/70-15
tyre Metzeler supply, I thought I would ask them direct to see if they
thought it would be safe for the V* standard back wheel (for my own
piece of mind) and this was there reply!
We cannot recommend you fitting a 200 section tyre to a 170
section rim, in our opinion it would not be safe as fitting an oversized
tyre to your rim would distort the shape of the tyre (giving it a much
smaller footprint) and adversely affect the performance of the tyre.
I know a lot of you have already established that but I just thought I'd
post Metzeler's reply, so any one still considering fitting one can have
a read. Hope you don't mind!

From Big Boo:
For those who are wanting to
mount and balance their own tires, I run through tires on 4 bikes like a
baby on cabbage....soooooo
This is what you do...
Look at harbor freight tools....they will discount their portable tire
changer and motorcycle attachment regularly....now you have a decent
set-up for less than $100. The built in bead breaker is really worth
it...Yes you'll need a good tire iron, don't forget the handles of your
large open ended wrenches, they make a great second tire iron. and also
a little gadget called a bead stopper....cheap and VERY useful...first
time you do this a helping hand is invaluable, but it is really just a
bigger version of changing a bicycle tire...now you did change your
bicycle tires right?
Now balancing...lets do this old school shall we. (it is ALL you
need).....you need two straight backs...I use steel rimmed card table
chairs. I kid you not.....with the wheel on the axle, axle across the
back of the chairs (level of course), spin the wheel. Mark the low point
(where it stops) straight down....spin again, if it stops in the same
place, you have to add some weight...try a little at 90 to 180 degrees
away from the bottom ..spin again...mark where it stops. add weight
opposite the low spot. You do this (say one beer's worth if you drink
two you ain't paying attention) you should get the tire where it does
not seem to want to stop in the same place every time....damn, now you
drank too much!!!! no...just kidding -- you're done that's right...can't
get the tire to stop in same spot 3-4 out of 5 times, you got it
balanced. Now show this to your buddies...beer in hand saying "yeah, my
grand pap taught me this when I use to wrench his Vincents that he raced
flat track".

Car Tires on Bikes
(updated 04/15/09)
This is one of
those topics that should be banned from polite company - it relies 100%
on "I Believe" (just like politics and religion.). However,
the topic continues to rear its ugly head - primarily because folks look
at the much lower cost of car tires vs. MC tires - and strive to save
the bucks.
From a Dark Sider": "Tires
are religion, and in the motorcycle arena and our litigious society are
viewed very much as a "dark art" and are seldom discussed rationally."
From "SilverBack":
On one side you have
the folks who call themselves the "Dark Siders" who advocate saving the
$$ or getting, to them, better performance characteristics. You can
visit their forum here: http://forums.delphiforums.com/DarkSiding/messages
. This is a group of riders who have tried car
tires on MCs (at least on the rear - no reports of trying them on the
front) -- an none of them have reported any adverse effects, accident,
failures, etc. These are the "advocates". They appear to be
driven by desire to save cost, or to get some other performance benefit.
On the other side, you have
the rest of the MC riders, who stick with MC specific tires on MCs.
These are the "conservatives". Motivation? Inertia, belief in ride what
is designed for MCs, lack of "enlightenment" - all of the above?
Strong aversion to risking their necks?
In the middle are the
"experts" - the MC and MC tire industry. The "experts" all support the
use of MC tires for MCs and decry the use of car tires for MCs.
Why? Inertia, lack of enlightenment, vested interest, fear of
litigation, all of the above, whatever?
From the 05/09 Issue of
MCN - Motorcycle Consumer News:
"It is very simple: Just don't do it! Car tires are not designed for
the leaning and side loads generated by motorcycles. If you don't
believe me, call a few tire manufacturer tech hot lines or visit the
Q&A sections of their web site. With the exception of sidecars and
special sidecar conversions, there is absolutely no safe or proper
way to use a car tire on a conventional motorcycle. As Forrest Gump
said, "That's all I have to say about that.""
What do we know?
-- A small percentage
of MC riders have, reportedly safely installed car tires on their MCs.
Small numbers do not make a good fact base. At best this is anecdotal
information.
-- MC tire manufacturers
spend $ and time trying to improve the performance characteristics
specifically required by MCs.
-- MC tires have to meet
different running, performance characteristics than car tires
(2 vs 4
wheels, leaning in curves, etc).
-- Car tires are designed
for car use - and not designed to meet the needs of MC specific
performance (may work, but not by design)
-- A hell of a lot fewer MC
tires are sold than car tires - volume may affect price.
What don't we know?
-- Is there a higher profit
margin on MC tires (or is the completion enough to hold that in check?)
(Vested interest?)
-- Does the added
functionality of MC ties support their added cost?
-- Why have their been no
long term controlled tests, or have there been? Where are they?
-- Long term, under all
typical MC riding conditions, do car tires "deliver"?
-- Will my liability
insurance cover me in an accident? will my collision insurance
cover me in
an accident?
What is the risk?
Risk
has two elements:
---
Chance of Occurrence - what is the likelihood of failure?
--- Severity of Impact - if it
fails, will it kill or maim me?
I for one, will not assume the risk of using
a car tire on my MC - and I loudly and vocally advocate against anyone
else doing so.
A final few words:
DON'T DO IT!
The purported added miles of use and the purported lower cost per mile
ridden on auto tires on your bike is NOT worth the risk to your life,
limb and bike.
I don't care who has done it! I don't care about their endorsement!
Ask yourself a question: Is the few dollars I may save worth the risk to
my life?
"The Management"
(Or at least the SilverBack part thereof)
You need to decide for yourself!
