I've been using Cooper Discoverer AT3 for a few years. We ordered from Tire Rack while in Oregon. Saved on sales tax. Been coast to coast. Couldn't switch to G614 because our rims are not rated for the needed pressure.
Your 2013 3150RL Montana came with wheels rated for 110 P.S.I. You are good assuming they are still installed....Couldn't switch to G614 because our rims are not rated for the needed pressure....
I will pay the extra! It is not just about quality.G614 from Goodyear
USA tires vs china
Enough said
I have a 3120RL Montana 2020yr. It came with Sailun R80 tires. In Canada R80 is almost impossible to fine, but I can get Goodyear G614s in R85. Will the R85 larger diameter be a problem on the 3120RL?
