I've been running 22# in my 17" 275/40 in the front and 335/35 in the back. After about 11k miles, I have ever so slightly more tread in the middle of the tires. The tire gauge shows 50 on outside, 58 in the middle and 43 on the inside of the front tires (tread depth). The rears show 53, 56 and 46 respectively. I can't find my tire gauge now but the numbers must be in mm. I think I'm going to bump the pressure up to 28#. I've got some autocross experience showing higher pressure would help. The tires are Michelin PS/2.
