Dude.. go check your psi right now then, whens the last time you did? Your probably eating right through your tread..

I completely change the air in my tires every 2 or 3 weeks.

And you guys aren't bouncing around all over the road? I've tried different pressures, but what worked well was what is printed on the door: 32 rear, 29 front. I run 215/45's on 17 x 7.5 rims, with stock suspension. If I go higher than what's recommended by BMW, the suspension gets all weird & bouncy, losing grip over bumps and the antilock goes haywire.

lol, it is pretty bouncy like it is, but it handles alot better with 45 psi than it does with around 35.

^^^Heh, maybe for you. Anything over 33-34 on my car, and the wheels feel like fricken basketballs.

**voca** · 11-10-2005, 06:38 PM

that could have to do with the fact that you, dudesky, are running 17in wheels and catalyst is using the stock wheels with a larger section height and lower tread width. but, I myself have 17x8.5in wheels and about 41 rear and 39 front feels right for my car.

On my low profiles I run 40-42 on the older tires (the 15" 36)

My summer wheels(in my sig) I run at between 35 and 40. My winter wheels I will run at the slightly harder then manufactures specs. My road bike i run at 110.

haha, yes. I ussually check my pressure every 2 weeks, after around a month, when im checking the pressure again, i just let it all out then put new air in, it only takes like 30 seconds extra for each tire.

I guess i should mention i have a compressor system at my house.. that makes it a little less weird.

Voca: im running 17's.
