Most tire manufacturers still put a yellow paint mark on the tire that is supposed to be aligned with the valve stem. This is the lightest part of the tire. That said, most tire INSTALLERS(I won't call them all techs) are doing an entry level job, that no one else wants to do, and they just mount the tires with the mark wherever it ends up. This usually means that they have to use excessive weight to balance a tire. Here is a link from Yokohama but other tire manufacturers use the same standard. Just scroll down to "weight method".

ah ….. Mmmmm ….. not exactly.

First, the mark is usually red - AND - it's the high point of uniformity (think roundness and you'll be close), not balance.

Second, the vast majority of wheels are NOT marked for the low or light point with the valve stem. With a few exceptions, the placement of the valve hole is random.

Yeah, I know, that is NOT what the Yokohama web page says, but they are wrong. Last year I did a survey of OE manufacturers and found only one (Chrysler) who match mounted using the valve hole and it was for uniformity, not balance. No one else specified the location of the valve hole - and since, by far, the vast majority of wheels come as OE on new vehicles (meaning the aftermarket replacement of wheels is by comparison pretty small), what Yoko said wasn't true.

HOWEVER, there is no harm done matching tire dots to the wheel valve hole - only it more than likely doesn't do anything of value.

Red mark is the heaviest point on the tire and yellow is the lightest point on the tire. I am sure that the tire manufacturers DO NOT know what they are talking about. I only posted this for information that may help some people.

We do and there is a difference. Load force balanced.
Four out of balanced tires aren't going to cancel out each other.

I held back on this to see what was said. I have owned one of my DPs since 1997 and have replaced the tires 4 times the other one I have replaced them once. All done by the same tire place and not once have they applied a weight and I have never had ANY vibration in the steering or otherwise. Old DP has 110,000+ miles and newer one about 70,000. I asked once and they said that they lined up a mark on the tire...Now this information may not agree with some of you and at first I wasn't sure but it seems to work on my units just fine. These are 22.5 wheels and one has aluminum and the other steel wheels. This is only meant to be an example, you decide what makes you happy.

From Yokohama's web site:

"....the red mark on the tire, indicating the point of maximum radial force variation, should be aligned with the wheel assembly's point of minimum radial run-out, which is generally indicated by a colored dot or a notch somewhere on the wheel assembly (consult manufacturer for details)......"

Please note that this only appies to Yokohama tires. Other manufacturers don't necessarily use red dots - some don't apply any marks at all.

I have all tires/wheels balanced.

I pay the tire tech $10 extra tip per tire, for showing me how well he has positioned the tire on the wheel to avoid egg rolling.

Each axle has Centramatic's.

Tires are on our RV's from 5 -10 years, depending upon what an owner feels is his comfort zone. (I target replacement of my tires at between 6-7 years of age.) So if you spread the cost of an $80 tip, and the costs of balancing to the shop, over those 6-7 years - well, it sure is not too much to do so[emoticon]!

Best to all, have fun, be safe,

Smitty,
You're making waaaaaaaaaaaay too much sense here for many RVers. Thinking ahead, and planning for longevity, even at a slight cost, isn't always on the agendas for some RVers. Not to mention, as has been stated, four tires on the back of ANY coach, don't cancel each other out. They're still OUT OF BALANCE.
