Re: whats the proper tire pressure???
Follow the instructions at the driver's side door lah.
If you're outta range of what's stated, then you gotta rely on the seat of your pants.
All pressures stated at 24 degrees C. After that you have to increase 10% for every 10 degrees C IIRC.

Re: whats the proper tire pressure???
if you read the matrix by the door side, there are two recommendation. one for normal 4pax and the other for 4pax plus luggage. based on 225/35/19" & 255/30/19" for 4pax+luggage, it say 260kpa (37.7psi) for front and 310 (44.9psi) for rear. however, on the 4pax only recommendation is F210kpa (30psi) & R230kpa (33psi)
mine are F235 & R265 tires which is slightly larger, so I tot I just increase a bit lo. cos I drive my family every weekend for grocery. maybe i will adjust to be in between. been raining a lot. better go do my pressure check during lunch.

Re: whats the proper tire pressure???
Until I got my e46, I would usually pump 34 - 35 psi per tyre all round.
The owner manual for the e46 was an eye opener.
It recommends 32 psi (front) and 39 psi (rear) for a 225 x 45 x 17, which I have followed. I also check the max recommended pressures on the tyre walls just to be safe.
Interestingly, the manual recommends pressures up to 49 psi for the rears, depending on the tyre size and passenger load. Personally, I would be wary of exceeding 40 psi on any tyre.

Re: whats the proper tire pressure???
2.0 bar is 240kpa or 35 psi
I will say this for the last time
DO NOT pump more than 35psi. You will get uneven wear in the centre of the tyre, more road noise, less grip, less front end feel and harsher ride. Never put a different amount in front or rear, always the same. If you are anal, 33psi is optimum.
Terry since when do you have 20's?
