ok, when I have my stock wheels on, my steering wheel has no vibration at all, but after I got the HP EVO Wheels, the steering wheel vibrates and shakes when I get close to 60mph... weird...

anyone know anything about this?

 

Try a search on "steering wheel vibration". There was a thread earlier about hubcentric adapters. What size and width are new wheels? Are they balanced well?

 

they're 19x8.5 front / 19x9.5 rear with nitto tires, they were balanced at discount tire co.

 

i think they weren't balanced correctly. lexus are very sensitive to wheel balance, the wheels have to be balanced to tight spec

 

Have each wheel spin balanced while on the car......guarantee that will take care of it but it may be hard to find a place that can do it.

 

Wheels for the GS are supposed to be road force balanced...(so says the dealership)..
