My rear tyres lasted only 17,000 km :(

Actually BMW don't recommend wheel rotation even if all the wheels are of the same size.

Care to explain more?

zhul is right! :top:

..because of the requirement to bed in rotated tyres all over again after rotation to achieve full tarmac-tyre surface contact, before which, traction is compromised. Camber for each wheel is never identical. The slightest degree of 0.01 degree of camber variance between tyres will cause small percentage in compromised traction once the concerned tyres are swapped, effect multiplied by the vehicle speed!

The act of rotating tyres is to salvage tyres to maximum mileage over Ringgit, and not optimising traction. So there's a small price to pay and BMW is not taking any chances! :top:

I almost totalled my E90, driving with DSC shut off, in heavy down pour, using freshly left/right rotated rear tyres, with one of them suffer severe inner wear, due to one side overly negative camber, running with fresh camber settings, at the curve outside of Pizza Hut Tmn Tun, Kepong bound. Lucky the car catches by itself after an over 15 degree oversteer. The body roll during the flip probably cause the tyre to find a better traction spot. If stiffen anti roll bar, habis!

Hmmm just to clarify, rotation means front back left right or just front back? If all around that means the tyre should be permanently fixed to the same spot.

Guys; need some help. My new 320d PE seems to drift to the left when travelling above 80km. Went to Lim tyre and they told me the best way to solve this is to "camber" the front 2 tyres.

Hence the problem is solved but the sterring feels really light which when taking corners and the car feels light when above 120km right now.

Should i reset back the original setting and bear with the drifitng to the left feel without comprimising the "light feel" of the steering. it feels weired as if the car seems to be floating on air. I miss the heavy feel of the m.

Thanks.
