Please when responding regarding your tires, include the model number, not just the brand. Very important as there are differences between model of tires.
Having said that, I just got pricing from my local commercial dealer who gets a lot of RV referrals from General RV. He said he rarely replaces Goodyears or Michelins in kind, most go with a different tire, and he gets most of his customers into Toyos. I need 245 R 19.5's on my rig and he recommended Toyo M143 as his most popular RV tire in that size. G670's were $554 per tire installed, the Toyo M143's were $387. Right now I have G670's on the front going on 6 years, the rear duals are G647's and are going on 9 years, all tires look to be in very good condition, no checking, little tread wear and little rivering on the steer tires. Going to Toyos saves me over a grand.
