View Full Version : New wheels / tires - 22 wheel weights on one wheel

Got a wheel and tire package shipped (17" Vintage Wheel V40 and Nitto NT555s). Three wheels have between 2 and 7 stick on 1/4 oz weights in one area but one wheel has 22 all in one area. I would think this would have raised a red flag since it is so far out compared to the others. What is an acceptable limit and should I be concerned about a defect and return this wheel/tire combo?
It appears that both the wheel and tire imbalance are both in the same spot. You could have a tire shop move the tire 180 degrees on the rim and try to rebalance it and see if the weight distribution is better.

That's the proper way to do it. Any properly trained tire tech knows this. Back in the day when I worked at a tire shop it was very common to have to do this with the bigger mud tires. If you didn't, you would end up with a fist full of lead on the rim. While I doubt there is any foul issue with either the tire or the rim, I would at least call the company you ordered from and see if they will refund you a few bucks since you are unhappy and will need to take the one to a local shop to have the tire bead broken, the tire rotated on the rin 180 and rebalanced.

Look on the tires. Is there a red or yellow dot painted on them? That's the tire heavy spot and it should be mounted opposite the valve stem.

I've always thought match mounting can be done by 2 methods. I just had tires mounted a couple days ago and because there wasn't a radial runout mark on my new Rushforths I told the shop to weight match.
Uniformity method (the preferred method)
Red dot on tire is aligned with the colored mark or notch on the rim if it has one which indicates minimum runout of the wheel.
Weight method
The yellow dot is supposed to indicate the point of LIGHTEST weight on the tire and gets aligned WITH the valve stem.

Interesting...I always thought it was the heavy side. Could that be Yokohama specific?

lots of great info here. First i would take it to another shop and have them recheck the balance. That is a lot of weight. Im actually a district manager for National tire and battery and unless they are mud tires they shouldn't take that much. Worst case they can static balance them. on car tires you are looking at no weights to 3oz or so would be average.

Dunno Andrew, the only high performance tires I've had installed were Yoko's so I went with their suggestions. I've had a couple sets done by both methods and the uniformity method seems to end up with less weights. Tire rack thinks the only way to do it now is with the newer Hunter balancing machines that can measure runout and tire force variations under load. I had a hard enough time finding someone who could even mount my new combo nevermind trying to find someone with such a machine who also knows how to use it.

Yes, they do have yellow circles. The wheel/tire in question is not mounted as you said but the other are close. The one I have an issue with has the dot and valve stem about 90 degrees apart. This may explain the problem.
I'll take shizzy's advice and see if the place I bought them from will give me money back that I'll pay a local company to dismount/remount/balance.
Thanks for all of the good info!
A couple of things- lead weights are progressively being removed from the market in place of coated steel or even zinc (for enviro reasons). So get used to seeing larger groups of weights.
I always balance at .25 OZ less than the machine calls for, and never have a problem.
I guess that comes from the fact I do NOT believe in masking a problem with weights...or that you even can.
Can't say as I've ever balanced a performance Nitto. I have no idea if some are way out. As I've said before, some of the "name brands" (I wouldn't quite consider Nitto a name brand yet, sorry) are among the worst...
