What Psi in 37s
 

What Psi are you guys running in your 37s on the road/highway. Just got my 37in nitto mud grapplers, and they will be on a 2008 2dr with 513. Thanks!

I ran mine at 22 I run my iroks at 10 but they are bias

37 toyos and on road i run them at 26 psi.

I did the same with that size tire, for road trips I would bump them up to 32 for a bit better handling and gas mileage

chalk test for best results

but...37" MTR's, 8" wide wheel, 28psi

I chalk tested my 37" MTR-k's and they were even at 22psi on a 9" wide wheel. Anything above 24-25psi and the ride gets much worse.

Ok sounds like a found round number is 30 psi until I can do the chalk test

I bet you drop it lower. At 30psi mine ride like round rocks.

Well I just need a good round number to ride on till I can do the chalk test.

Yeah 30psi in my 37's was way too much. Only rode on the center of the thread, and the ride was horrible.
Start at 25psi and work from there
