I purchased a new set of Fox Racing EVO 6 Alloys (17" x 7.5) at the weekend. After getting them fitted I took the car for a spin and noticed that I was getting feedback from the pedals. I went back with the car and they balanced the wheels again. I then went back out and it was better, but still some feedback. I contacted Lexus and they advised me to check my tyre pressure. I changed the tyre pressures to 35psi all round.

One of the front tyres had less tread than the other, so I bought a new tyre and thought this would solve the problem. I have since bought another 3 tyres and still the same.

I have had them balanced 4 times and the pressures checked.

When I take the car for a blast when I get passed 60 I start to get vibration from all the pedals, if I go above 80/90 I get shaking from the steering wheel.

The place I bought the wheels from have aske me to drop the car off on Tuesday so there engineer can have a look at it.

Does anyone have any ideas?

I noticed that the wheel has a different offset.
Front
7= 40 and up 215-235
7.5= 42 and up 215-235

Rear
7= 40 and up 215-225
7.5= 40 and up 215-235

If the offset is not correct could this be the problem???

do u mean that u have wheels with 2 different offsets on the car?

EDIT: just realized what u were saying - offset difference shouldnt make the car/wheels vibrate - just a thought - have you got the correct wheel nuts for those wheels??

Which will also mean the tracking's going to be out ..... ?

are the wheels hub-centric or nut-centric? If they are not hub-centric they will not center correctly on the hub. You should be able to get a hub ring to convert the wheels.

The wheels came with hub-centric ring. The nuts came with the wheels also. Do you think I should check the tracking??

Some tyre/wheel places are better at balancing than others. One down the road took several attempts with their supposedly recently calibrated machine ("just done a roller sir" and all that) but still got wheel wobble. Took it to another place and they did it fine.

Just back from the garage. He moved the back wheels to the front and front to back. He also re-balanced all the wheels and it's cured. Mechanic has no idea what it could have been. Thanks for all your help.
