So I decided to go with to go with the Vision 7.5 Heavy Hauler and the Hercules 19.5 265's all around, so what would you advise running them at? They are rated to 123 psi max, but I'm pretty sure I...
On my SRW with 19.5s, I ran 80-90 front and 95-105 rear. The front tended to wander more with higher pressure. I could have had more air in the rear, but at 100 I was 20 lbs over the stock tires which seemed plenty.
Fwiw, my F450 which is a DRW has air pressure ratings of 80 front and 75 rear for the 19.5s to reach the 14,500 GVWR.
