To all those out there running 10 ply tires what are you running for air psi? I just installed my 275/70/18 Yoko Geolandar's and they are E rated 10 ply tires. I set the cold psi to 40psi but I'm thinking now that might not be enough. Shout out to everyone who recommended this size btw. They really fill out the wheel wells nicely and don't rub at all. Think it will look much better once I get my lift installed(hopefully this weekend) though.
