tramlining

[han2u]

Just changed my E36 15" rims/tyres to 17". Its been a while since I last used 17" (on a E30) and I dont recall this experience. Is it normal for the car to tramline? http://en.wikipedia.org/wiki/Tramline

If I'm not mistaken (someone correct me if so) tramlining is more likely to happen with:

1) Wider tires (likely case for you since I'm sure your 17s are using wider tires than your 15s)

2) Directional tire tread design

Meaning you didn't have this problem with your 15"? I have this problem too, had it ever since I bought the car :hmmmm2:... though not very bad. My mechanic suggested WIDER tires to eliminate this problem :76:, which I tend to disagree as the original e36 had smaller tyres than what I have now. I was thinking probably the steering assembly... some worn linkage or bush etc but if you are sure you didn't have this problem before changing the wheels, it most definitely has to do with that :shakehands:
I am using 18" with 225 front and 235 rear - directional tire tread (which is quite common these days) on my e36. Used 17" before in another e36 and never had any problems.

If all has been checked out & no problems found, try to reduce tyre pressure to an acceptable level. Works well for my ride.

its the offset difference in both rims you have which causes this. you can simulate this problem by just inserting a spacer (calculated from the bigger rims offset) unto the smaller rim which did not have the problem. also known as bump steer.

Forgot to update this thread. I refurbished my steering rack and replaced both my tie-rods. Problem solved. Thanks.

Ever since changing to Falken 452 my car tramline quite a bit ... increasing the tire pressure reduces the tramlining effect ... in my opinion the type and brand of tires does contribute to tamlining plus worn control arm bushing and rear trailing arm bushing also contribute to tramlining ...
