So I just replaced the Hankooks my rims came with ( 245/35/20) with some new toyo proxes 4 ( 255/30/20) These tires are way quieter and look much better but now my car starts to vibrate a little and the steering wheel shakes at around 50-70 mph once i go over 80 it goes away and also doesnt do it a low speeds. All the hub centric rings are one, and the wheels are 1 peice chrome wheels.

Add suggestions or advice as what it might be? Im going back next week to the tire guy since i never have days off from work.

Thanks!

My bet is that the wheels need to be re-balanced on a good machine (i think hunter 9700 or something?). good luck.

Look on tirerack.com for a local shop that does Road Force balancing (which I think is the Hunter 9700). Also, make sure you ASK for the Road Force balancing as most shops have more than one machine or run the 9700 in the standard mode. I had this done on my GS and the car rides very well (I had slight vibration in the same range as you). They had to re-mount 2 wheels (included in the price) to get it perfect, you may have a similar issue.

maybe the guys who changed the tires forgot to put the hub-rings back in?

Ok, Got all the wheels rebalanced, same problem, they are saying it could be my new tire size, I went from a 245/35/20 to a 255/30/20. Anyone else having this problem. I know the 2nd gen GS are very sensitive to wheels but there are so many people on this forum with 20's and i dont see everyone having the same problems as me.

Right now i feel like putting my stock wheels on because the vibrations on the car and steering wheels are so annoying, My car rides worse with my new toyo proxes than it did with the cheap kumhos maybe i missed up on the tires size.

Anyways looking for any advice on what i should do!

It is hard to find a place that can do this but if you do it will take care of this problem. Each wheel needs to be spin-balanced while it is still mounted on the car (and you probably won't be able to rotate your tires without doing it each time). Not many places do this anymore and if you find one that does they will probably be slammed with business from people with aftermarket wheels. My place charges $15/wheel but it definitely takes out any shimmy.

Well one of the shock bolts on my new Tein CSs were lose and causing mad vibration, problem is now fixed. Thanks guys!
