Hello, thanks for the video! I have a 2007 Hummer H3 with mud grapplers 315/75R16 on 8” rims. I did a chalk test and currently I am running 28psi front and 25psi rear, does that sound correct?
Would you recommend going a little below 30 psi? Like 25-28? My 2004 Tahoe z71 door sticker says 30 psi stock but I’m running 17x7.5 on 37x13.50 and the ride more in the middle
Yeah probably wouldn’t hurt to try, but you may lose some MPGs if you go too low and the truck will feel sluggish. The way tires on the skinny wheels are just going to squeeze them to where they ride more on the center a little. Too much psi just makes it worse so worth a shot
