tire pressure question

Express · 10-08-2011, 11:15 PM

i have a 330i with sports package but right now im rockin 161's with RFT's. since my car came with 18's i dont know the proper specs for the 17's. if someone could inform me of the pressures that would be great.

also, my front tires aren't looking so hot so what pressures can i use to preserve them just a little bit longer?

thanks!

the manual has specs for multiple tire sizes and loads at different speeds.

generally if the center area of the tread is wearing down fast in relation to the outer sides, you are overinflated.

other way around... these tires were underinflated for a bit. the middle is perfect..

make sure you reset the TPMS once you get them set right.

IIRC, 29 in the front and 35 in the rear on the 17" RFTs.
