bigger tires, whats your PSI?

when i first got my tires the kid set them at 40PSI. i dropped them down to 32PSI according to my door. which improved traction and handling alot, and made a HUGE difference in ride.

However, my rear tires werent making 100% contact and i found this out in a parking lot. so i dropped them to 30PSI in the rear.... this got then to about 90%. then, today, I dropped them further to 28PSI in the rear, now they are making 100% contact, and overall traction has improved alot.

so im curious what others are running for tire pressure in their bigger than stock tires...

I think this has to do with the fact that the *** end is so light, and being a 4ply tire.... could be that its 'el cheapo' tire, but thats besides the point

we base our tire pressure we put in the tires on what the max cold psi is, and the size of the vehicle. most tires get 38-50 psi. granted they are 50-65psi cold rated. if the owner feels they want to change that, its up to them.

I got 28 all the way around. Perfect contact patch.

I was down to 18 to get decent contact on my at's.

These are offroad pressures of course...

I run 32 on hwy

This was with 35" BFG MT's, but anyway somebody on here told me to drop mine down to like 30 PSI and I could not get traction in the rain. I put 35 in front and rear and was happy with them.

I think im running 24-28 In the front with my 35s for full contact. And the rear is something like 18-22. I cant remeber the exact numbers though..

Thats the reason i'm running such a low psi. If I bump it up too much I don't get a good contact pattern. I'm sure my 8" wide wheels contribute to that a bit though....

I was running 32 all the way around in my BFG's, and I noticed the outsides of the rear tires weren't touching the ground...so I tried 30...same thing...28...same thing, so I said screw it and just run 35 in all four now.
