I would appreciate a starting point on air pressure with these tires.
My application is 3000lbs running mid 7's. Could someone with a similar application give me some advice.

I would start them at 9 PSI and suspect you'll end up anywhere from 8.5 to 10 PSI.

Thanks,

Jason, what about a 2600lb car running mid 7's? Been using a 15 x 33 tire with about 6.5 - 7psi.

I think you are in the ballpark, but it wouldn't hurt trying to go higher. Eight PSI would not be unreasonable.

Hi, Jason!

One more 33x10.5 w question for you....Vehicle race weight is 3758 (2219 front, 1539 rear). Full size truck, backhalf, ladder bars, double adjustable coilovers..Nowhere near as fast as these guys, but slowly getting there (low 6's eighth mile now, will be in the 5's soon!)...

What tire pressure would you reccomend? Not sure if it matters, but I am not running tubes....

For your application, start at 10 PSI, and go up if you want to change anything.
