Changed my front tire pressure last week....

to 35 psi from 32psi. It has made a world of difference in the way the car rides and handles. I didn't think 3 psi would matter much but it does. The car feels a lot more stable.

What pressure does everyone use these days?

I have 35psi in front and 41psi in the rear. Sure seems a little high, but it is BMW spec for full load. Its not to rough of a ride. I like it.

Get your tires filled with 100% nitrogen. The molecules are larger than oxygen (normal air has 21% oxygen) so your pressure won't drop (they won't escape through the rubber). I did it with my tires and after 6 months/10.000 miles it didn't drop a single psi in neither of 4 tires. Saves a bunch of "checking the tires" time. Greetz

good idea, but where do you go to fill it with nitrogen, its not standard at a gas station

Try your local Air Force Base - you just have to know someone that works on the FlightLine (you have to know them REAL well)- and who works weekends.
Thats how I fill my tires on my '69 Mustang (I was the one working weekend duty).
With that stuff, you could check your pressures on a 68 degree morning, Drive a hundred plus on the freeway when it is over a hundred degrees out, and the pressure would still be the same (Nitrogen is an inert gas).

Yep, that's why they fill airplane tires with pure nitrogen - prevents heat related variations in air pressure - pretty important when you are slamming a non-rotating wheel down onto pavement hard during landings.

Although I'm in the airforce and probably have the opportunity to fill them at base, I let the local Tirecenter do it for me. Cost me 14 euros. In Holland almost every tirecenter can do it for you. Don't know if U.S. tirecenters will sell those services though.

that's really cool. i'd pay about $20 to get that done! (if it works as announced) now i just have to find a place to get nitrogen. some place other than an air base that is..

Perhaps you can get N2 from Welding places where you get the the BBQ tank filled or at a Paintball store. Need to do some research on a container and fittings.
