I need to do a routine visit to the air pump. Just wondering what pressures you guys recommend for urban driving in the new M5...

I plan on setting the tires at the "higher load" recommendations on the door post, and then adjust downward to suit for normal driving

I started running 35 rear, 37 front cold now. For drag racing, run low pressures on the rear tires. For high speed, you need higher pressures. Here in the USA, I just run close to spec settings since I never sustain anything higher than 100mph for too long.

I was running 38 all around but I seem to be getting wear in the centre of the thread only i.e. overinflated. I think I'm going down to 36 all around for now.

Don't you love it when these old threads come to life again?!

I had been running 38 front and 36 rear, but recently dropped it to 36 front and 34 rear. The tires are 20" PS2's. I made the change based on the all-around feel of the car and not tire wear.

Since I frequently go up to a bit over 100, I have my rears at 46 and fronts at 41.

Besides, shouldn't high performance tires be slightly over inflated.

My 540 I have at 40 rear and 36 fronts - they have 17" Goodyear Eagle F1's.
