    DR tire psi

    Just trying to get a base line idea of tire psi for the upcoming track day. What are you scsb guys running for psi on your DR's for maximum bite? And are your wheels screwed or not? My tire is 295/65/15 MT

    id put 30lbs in them and let them sit for a couple days, then when at the track drop them to 20lbs and make small drops until you get good bite, then stop!

    I'm running 23 psi on the street. I drop to about 12-15 for the track. I'm running ET streets. I agree with sneeky, just drop a pound or two at a time and find the right pressure for your setup.

    But i am very curious to what other people are running. Those are just the numbers that work for me. But my truck is also very squirrely at speed. I really should take those things off haha

    alot has to do with rim size for that given tire

    so need to know the rim width first

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    My setup is acting funny. Et streets (bias ply) on 15x8 wheels. Tires are 12.5x28 and my truck always makes about a half rotation then hooks. Haven't been able to get it to work right yet. 14lbs seems to work the best for me.

    Too wide of a slick for rim size. You'll never use that tire properly... A 12.5 tire needs 10" minimal to get an ideal contact patch
