Hello wondering if anyone has any recommendations for tire pressure on our new ride. We have a good starting point of 12-13 but looking for any real world experiences here. The car is a 29.5x10.5 stiff sidewall M/T. Car weighs in at 3350 and has 1300hp all motor deal. We are planning on racing it this weekend for the first time just looking for any input we can here. Have not had the oppourtunity to test at all with it so the more info the better.

I run mine between 10-11lbs but im only making about 750 so you will need to test with it.

Thanks for the reply, I appreciate it. I know I will have to test, kind of obvious really. But that is hard to do with this type of car. Just not tracks good enough on test days to make any real headway and we are still fighting some engine gremlins that I hope are solved but wont know til that first hit. Just looking for what others have experienced. I am one of those run as much tire pressure as you can get away with. For many reasons I run my big tire car with way more pressure than most people as well.

I run right at 12lbs ... 29.5 - 10.5W (which is a stiff wall) and I run tubes... It seems to be the best pressure for my rig. 1050-1075HP. 3400 plus lbs... Good luck, have fun!

Yeah, 3300lb car, 1000hp with juice, 8.9 @ 155, running 20 psi in my 30 x 10.5's on a 10" wheel, hooks perfect, no tubes, no rim screws, no beadlocks. This help confuse you even more? ;)

No substitute for testing, just the way it goes. Good luck.
