Do you belong to FMCA? They have a tire buying program from Michelin and have good prices. Would pay to join just to save on the tires. Last time I bought tires was in 2010 and that was before FMCA had the program in place. Since I needed 2 305/70's and 4 275/70 tires I contacted a large truck/industrial tire place on the west coast (not Les Schwabe). Took them a little while to get the 305's in but they were only a few weeks old. They took the old tires and wheels (went to Alcoa wheels at the same time) to pay for the mounting and front tire balancing.
