Tire PSI to soften ride?

Hey all,

I am wondering what PSI you guys are running in your tires? I have 295/60R20 Nitto Trail Grapplers Load Range E 10 ply (Almost the exact same as the Toyo M/T's I believe) and I am wanting to soften up my ride. I run 55 in the rear and 58 up front. I do pull a skid steer from time to time and then I am hauling about 9k.

Would 50 rear and 55 front make much of a difference and still be fine for occasional towing? We have snow too so any help there would be great. Is anyone going lower than 50 and still pulling a trailer?

TPMS light wont bother me. Truck is a 08 extended cab short bed and it rides HORRIBLE.

I have Toyo MT but in a 38/15.50/18 and I run 35 ft and 32 in the rr.

Now your tires are smaller and the pressure is going to be higher.
Here's what you do want to do that will help: drain off the air and put in nitrogen. It takes a couple of times of bleeding and filling with nitrogen to get all the air out. But the big difference is nitrogen does not expand like air so they won't climb in pressure from longer drives. Try lower pressure and see how it handles. The thing to watch is the pressure of the tires when towing, if your too low on pressure they will get hot and pressure will climb. As long as it tracks good and pressures stay in check your good.

So yea he'll yea drop some pressure and put in nitrogen.
