I have a set of M/T 275 Drag radials on my duster. Planning trip to the track this year, what is the starting point for air pressure in these, and a min max if there is one? 3300 lb car with driver, 525 hp 552 tq. 10 position adjustable shocks on all 4 corners. With slicks i used to just keep adding air till they spun, then drop down 2 pounds.

With adjustable shocks, you have much larger window than just adjusting tire pressure.

Shocks are another BIG part of the puzzle. We run @ 18/20#s. 3600# brick

Yes will be a test and tune deal. Will start at 18 psi work from there

As mentioned there are a lot of variables. Track prep, weather conditions, shock settings. ....... 18 is a good starting point

lot of tracks now have no traction because they'd been closed. Not enuff rubber down an lack of prep.

Like said already, 18 psi is a good starting point. The more pressure you can run, the faster it'll go. I started w/ 17 and ended up w/ 22 psi...when the track was prepped really good.
