Hey guys, i just bought a couple of race star wheels and MT radials. Over the weekend i had the tires mounted onto the wheels and balanced at a local shop, i brought the tires home and put them on the myself, took the car for a spin and i noticed vibration at all speeds especially over 65mph. I've never had drag radials before and wasn't sure if this is normal for them.

Today i took the driver side tire off and noticed that wheel has more weights than the passenger side, not sure if that anything to do with the vibration (oh and they are sticky weights btw) should i take the tires back and have them re-balance the tires, or is this normal?

 

Did they balance them using a hub centric or lug centric machine? Are you running skinny's on the fronts?

 

Get them road force balanced.

 

IMO some of these cars don't like other wheels besides stock. My car has had vibration issues since I got 20" wheels. Nobody has ever been able to completely cure it. Several road force balances and 3 different sets of tires. Also mine has different amount of weights on different wheels. Two of the wheels have no weight and other two have stacks of them in spots.

 

I don't know what they used to balance the wheels and I'm not running skinny's, just my stock 19's in the front.

 

Had you removed the little washer that keeps the rotor on?

 

I looked for those a long time ago and didn't see any but I can't remember if I checked all four tires but I know for sure I checked two and I asked one of the shops that did a balance to check. Whether they did or forgot I don't know. Might ought to check into that again

 

Yep. Check the washers against your rotors. Also make sure you torque them in a star pattern. Sounds like they are balanced just on the inside of the wheel which is not as true a balance but it should be sufficient. Does the vibration get better as the tires heat up? Some develop flat spots till they heat up.

 

I have heard of a few having issues and they resolved it by having the shop rotate the tire 180* and balancing then again.

 

Yep it works sometimes.

 

Just replaced my factory wheels/tires. Bought the car new and I picked it up the day it arrived to the dealer because ordered the car. Anyway. I was surprised to learn that not one of my factory wheels had less than 5 ounces of weight. One had 8 ounces. So I'm not certain I agree with this statement. Much of it is tires. I just got 4 new American Muscle wheels with continental tires and not on wheel took over two ounces in total. And no shimmy or vibration at high speeds. Maybe I'm lucky but they feel great on my car.
