Ok like the title says I just installed my Good Year Dura Trac 275/75 18's today and would like to know your recommendation on the best tire pressure to run. I have them at 35# but am thinking they would ride better at say 30 ish. What would you guys recommend?

 

Start at 30 psi, run a chalk test and adjust from there. There's plenty of info about tire pressure on the site, try a quick search.

 

Its tough to say your the one driving it so whatever feels best for you is going to be the right pressure. I'm running 26 psi and my mechanic thinks its too low but I think its riding just fine.

 

I run my 285/75/R17's at 30psi, rides smooth, straight and will no added bounce.
