Has anyone experimented with lower rear tire pressure. I know BMW say higher in the rear than front. I have started playing with lower tire pressure on 225/60/15 tires. I have been running 32-33 front, 37 or so in the rear and been experiencing wandering during my daily commute over 2 lane roads. By the way, the car seems to wander less with a full tank of gas.

I set the front at about 30 and rear at 28. Have not noticed any difference in "daily drive" handling, The turn in may be a bit slower on a quick turn. However, the wandering seems to have decreased slightly. Also, car rides much better at lower tire pressure, especially the rear wheels.

Any thoughts?
