for a tire that wide on a 8" rim it is very easy to over inflate them and then the tire just rides on the center of the tread.
You can take some chalk and draw a line across the tread and then drive straight for 50'
or so on pavement then get out and look to see how the chalk is wearing off. Then adjust the tire pressure accordingly.
The shop filled my tires to 70 psi after mounting them. It would rub off in the center and not at all at the edges. Think I'm down to 35 psi now.
Oh yeah I never fill them more than like 35 or 40 on this truck. Last I checked I was at about 30 though and now temps are dropping I wouldn't be surprised if there was only 20 or 25psi in there. They're definitely not ballooning out, if anything I'm only riding on the edges of the tread.
