I have an 03 tundra access cab TRD running 265/75R16 nitto terra grappler all terrain tires. These are bigger than stock. What PSI shoud I run? The max load is 60.

do the chalk test. to find it, search this forum. i just posted something about it two or three days ago.

or you can run the psi the dealer told you to run when you bought the tires.

I have the same tires in 8-ply. I run 42psi front / 40psi rear (unloaded). I've typically added about 2psi to the rear tires for every 100lbs in the bed.

Thanks man.

I've got the same tires, but in 10 ply. I've been running 55 psi, but I do tow some relatively heavy trailers, and they felt a little squirmy with less.

ive heard that the terra grapplers are not very good heavy load tires. but thats only one source so it could just be that.

I have them in load range D, have loaded the bed with well over 700lbs (and left the rear tires at ~40psi no less!), drove that load for 10-15 miles of combined city/highway, and can unconditionally refute that assertion.

well it must have just been the that one case then. i havent tried them seeing that i dont have them on my truck yet. so im kinda talking with no back. i still love those tire either way.
