[Matt_]

@33PSI, 33.5" tall. With weight of truck 32.75. 13" wide.

I got the Nitto trail grapplers, look at my garage as well and you can see them... Go Luck tire hunting

hey matt.. why do you run only 33psi

hey matt.. why do you run only 33psi

 

Thats just what I started at when i put them on. I run 35 rear and 40 front.

Thought it was best to run 40 all around?

Not as much weight in the back. I run 35 back there to keep the tread wear as even as possible.

yea but what if there an E rated tire (85) psi, wouldnt 35-40 be under inflated and wear wrong?

No, not for a 1500 series truck.

 

The load carrying capacity of E-rated tires is far beyond what a 1500 truck can handle. Inflating based on max on the tires sidewall will cause an over inflated condition that'll wear the center tread quicker, make the truck ride like a dump truck, and reduce traction due to decreased contact area.

 

Anything over 40 PSI really is overkill for a non-loaded 1500. I'll bump the rear up to 45-50ish when im towing the boat.
