I got new SCS Blaze rims and tires. Went with the 265 70 R17. I got them installed at costco and after driving less than 100 miles 3 sets of wheel weights have fallen off. Strange thing is i find them in the garage floor. If they were loose, I would think they would have flew off while driving (unless centrifugal force is keeping them on until I stop). Took it back to costco and the installer said well rim is close to brakes and that might be causing the weights to fall off. He said he put smallest size weights on the rims. That does not sound right. I just emailed SCS to see if this is not the right weights to use on the rims, but I dont expect to hear from them until monday. I have a 3k road trip and would like it not to vibrate all the way there and back.

 

Now that's a crazy amount of weight ... how many ounces ? If the installer cleaned the mounting surface ... they should stay intact.

 

I think each segment is .25 oz. They put 12 so 3oz? I could be totally off.

 

Aren't there two rows of weights on your seat? Or were they on different wheels? Speaking of which, did you mean the weights have fallen off of three of the four wheels, or the weight has fallen off one wheel three times?

We’re the wheels brand new when they mounted/balanced the tires? The wheels could have not been properly cleaned when they applied the weights. Not sure if all those weights in the pic were on one tire …..if they were then that’s a lot of weight. I’d ask for another tire.it could also be as simple as the tape on the weights was old/bad.

 

Yes, I gave them the wheels new in the box. I just crawled under the car and all 4 wheels have about the same amount of weights +/- 2 segments. So I don't think it would be the tires? I never really had issues with Michelins in the past. This costco has been installing tires on my IS and swagger wagon for years with no issues. This seemed a little strange on the amount of weights and it falling off.

 

Mine came off on one of my wheel during offroading in Colorado. I think it might have happened during a river crossing. But the weights shouldn't come off easily.

what is the offset of the wheels and how close are they to the caliper?

 

-10 from what SCS website states. I know a lot of 4Rs and other members here have SCS wheels. Maybe they did not clean the mating surface.

 

Some surfaces are close to impossible to stick weights onto with out scuffing the surface so the tape will bond. Most people don’t want to do that but it may be the only solution.

It’s possible for the weights to be hitting the calipers but not likely on a rim that big. The lower profile weights would help with clearance issues.

​​​​​​​3oz. Of weight on a larger tire and aftermarket wheel is not uncommon.

 

Most likely.

I just checked my wheels and the weights are pretty far from the caliper. And I do have just as much of weight as you.

 

Have the installer use a clean rag and brake cleaner and there should be no issue at all. You really do not need to scuff the rim, chemically clean it and you should have no issues. The other problem is they are double stacking the weight, if they just put the weight side by side it would hang on better to the wheel. As mentioned. that amount of weight is normal on a Chinese made aftermarket wheel or more aggressive tire.

 

Get the installer to start by rotating the tire 180 degrees. That rough and ready approach has reduced the amount of weights needed many times.

 

Yes ... wheels (the rims) are never perfectly balanced ... so if excessive weight is required, a good installer will check the balance of the wheel minus the tire, and then "clock" the tire to offset that imbalance ... minimizing the amount of weight required to balance the two as an assembly. Takes more time ... but something a good tire shop will do as a standard procedure. As a general rule ... a mere 1 ounce of imbalance at 60 mph applies 7.73 pounds of (rotating) centrifugal force ... so a huge stack of weights is not a good sign that the tire alone is reasonably balanced as delivered by the manufacturer. What amount of weight is considered excessive where the tire is considered unacceptable ? ... a subject of argument ... but obviously, less is a measure of better tire quality. And yes ... stick-on weights should never be stacked ... should be directly applied to the wheel (rim) after proper cleaning for best adhesion.
