Wheel balancing Whats is the maximum balance weight it should take to balance 275/40ZR17's on WS6 rims?
I ask because I have a hellacious vibration at 80+mph that I'm really thinking is coming from the wheels. And also the fact that each wheel has 15+ 1/4oz stick on weights to get it "balanced". Seems like an excessive amount of weight to get it balanced but idk? Tires were new when balanced. Rims/ axles are not bent at least side to side, check with indicator. Maybe egg shaped?
Drivers front 5.5oz
pass front 5.0oz
pass rear 3.5oz
drivers rear 4.5oz
Drivers front:
Is this normal?

Currently, your set up has a TON of weight. In other words, too much, therefore you have a set of questionable tires. What were the tires you had on before? FWIW, I just put a new set of Michelins on my Corvette, and each tire had 1.5 oz. of weight or less.
With respect to the wheels, original equipment GM wheels are usually hub centric, however the first couple of model years of the 4th gen cars had different sized hubs, front and rear. Therefore, the rears were hubcentric, while the fronts weren't.

Have tire shop rotate 180 degrees or go to a shop with a Hunter roadforce balancer. This machine tells you how much to rotate the tire. You can also measure the radial run out of the tires which should be less than 20lbs.
If they are unable to achieve this ten you have a defective tire. If it's a new tire they should be able to exchange under warranty.

Roadforce balance would be your best option as stated. Those tires are not helping. I had a set, they didnt require that much weight, but more than normal. Should be able to bring the weight down quite a bit by rotating the tires to a better spot on each wheel.
