How much wheel weight is too much?

I just had a set of 285/35-R19 Bridgestone RE-11s installed on a set of new 19x10 Forgestar F14 wheels. One wheel and tire needed 4.5 oz on the outside of the rim and .75 oz on the inside. The next heaviest is half that and one requires just .5 oz. I have two other sets of wheels (OE) and tires (Bridgestone RE-970 and S-04) for the car and several have as much as 3 oz.

I realize the balance of wheels and tires can vary widely and for regular street driving I wouldn't worry too much about it as long as there wasn't any vibration. However, this set is intended for high speed use and I want to make sure it's not indicative of an issue with the wheel or the tire.

Thoughts?

While there is no industry standard, the general consensus of what is too much weight is when it takes more than 1% of the assembly weight to bring it into balance.

Thanks. That is a good rule of thumb to remember.

Try and rotate the tire on the rim 180*, sounds like the heavy side of the tire and the heavy side of the rim are on the same side,this should make your assembly have much less wheel weights.

I considered that. I wish I would have caught it before I left the shop. I was more focused on making sure the wheels weren't damaged when I loaded them in the back of the pickup.

If you have to load and unload tires in your truck at various times then you may want to consider some Kurgo Seasonal Tire Totes and Kurgo wheel felts. I ordered some last fall and finally yesterday I opened the packages and wrapped all 4 of my SVE Rims with my road racing slicks. They really work well and now the tires look really nice in the corner of my living room. I should have brought them in from the garage sooner.

That's to much weight for a high quality tire and wheel like you have. Instead of 180*ing the tire. Have them road force balanced, they should have done it for that tire at least after it saying 4.5 oz. 180*ing is the quick poor mans way. a road force will tell them the high and heavy spot of the wheel and tire. and then tell them exactly where to line the two up for best runout and weight..

Yeah, that does seem like a lot of weight. I would not be happy with that, whether it really matters or not.

It's a little disappointing that the tire shop did not take the initiative to take care of it themselves. I think I'd go to a different shop, rather than trying to make them do quality of work that apparently they don't normally do. Road force balance sounds like a good idea but might not really needed, if there is no shop near you that has that machine. Mine are old-fashioned spin balanced and needed very little weight, and run smooth as could be . . . might be dumb luck, but shows it can be done.

Thanks for the input. I bought the tires at Discount Tire and I'll probably start by taking that tire back next week and have them try to remount the tire. If that doesn't work I may look to have the set road force balanced after that.

I don't move wheels and tires in the back of the pickup very often. I wasn't worried about them being damaged during loading as much as I was making sure the techs at the store didn't damage them during installation.

I bought something similar from TireRack for $45. I highly recommend any kind of tire tote as well.

Its discount tire. take you car back, talk to them about how much weight it needed. If they don't do anything or say that's normal get the manager. He will get someone to ridematch (roadforce) balance it. whether its just that one or all of them. I used to work there. It doesn't take very long. we would have done it before putting that amount of weight on.

I took them back today. They rotated two of the tires on the rims and took an ounce off the wheel with the heaviest weight (now 4.25oz total) and .75 oz off the other.
