Thanks Ivylog, just curious why u went with the 315 instead of 295? I assume the 11R's are a little less expensive than the 80's?
My front axle is just under 14K lbs and I go 5 psi over what's needed so a 295/80 required 110+5=115 psi while a 315/80 requires 95+5=100. The 295's on the rear only required 75+5=80 and the 11R requires 85+5=90. Yes the 11R is much less expensive and it's a very common truck tire. I'm using Firestone on the front and Hankook on the rear.
OP, if your front axle is 12K then I would run 90+5=95 but a 295/75 would require 105+5=110... a harsher ride and maybe a G rated tire.
