    TIRE Pressure...

    For my Subaru WRX my manual says to inflate the tires to 32psi on the front and 29psi on the back. But on the tires themselves (Stock Potenzas) the psi number is different. WHat psi do you guys reccomend inflating them to??????

    The numbers on the tires are the maximum pressure. The vehicle manufactrers always reccomend a little lower pressure than us who work at tire stores. They reccomend that air pressure to get the best ride, we reccomend the pressure for the best tire wear. I personally run 36psi in the front and 34 psi in the rear.

    Thanks a lot.

    Do you have any recommendations on a inexpensive tire pressure gauge. Also do you think i should buy one of those inflation devices or just go the the gas station everytime i need to fill up air.

    I run 37 front and 34 rear on the stock tires. On my summer tires, I run closer to 39F and 35R. I just picked up a mini air pump from Target that plugs in to the cigarette lighter. I use a digital air pressure gauge that I zero out before each use.

    Stay away from inexpensive gauges. Most are inaccurate so what would be the point. I picked up a decent gauge from Harbor Freight for less than $15 and it's very consistent. Get one with a release valve and flexible hose. And btw, I run 38 front and 35 rear. No magic about it, I just want to be able to break the tires loose in case of an LS1 encounter or similar. Ha!

    Was just about to post a new topic and found this thread

    I was noticing the other night coming home that my steering feel was really heavy at slower speeds and it definitely felt like my tire pressure was too low.

    So, I let the car sit overnight. First thing the next before going anywhere, I checked w/ a digital fancy-schmancy gauge and it read 31.5 on front tires and 32.5 on back tires.

    I'm guess after reading this thread that I'm running signifcantly too low for day-to-day driving? Sure feels like it....

    thoughts/comments plz
