Tire pressures running 37x13.5r20 Nitto Ridge Grapplers
I just bought the 37x13.5r20 Nitto Ridge Grapplers and was wondering on tire pressures. The shop maxed them out at 65psi but seems to ride too hard. Lowered all (4) tires to 60psi and that has helped. Was just wondering how low others were running theirs and tire wear at those psi settings. Should i also run lower in the back since it's lighter? Add air if towing or hauling of course....
Note: Also put the 5" Rough Country lift to fit the 37s
thanks,

most guys will back them down to 45 +/- PSI. max pressure is only meant for max haul capacity requirements. Past that it'll ride super rough at max PSI!

Thanks! Was hoping i could run them lower than 60psi. I'll try 50 and see how they feel/ wear.... thanks again!!

I am running my 38 x 13.5 x 20's trail grapplers at 42 psi. I need to measure the wear but looks good.

Nice rims. I'm running the 35x12.5 on 22" Mavericks. I'm trying to figure out what tire pressure to run as well.
