I replaced my last 22.5" G670's when they were 10 years and 3 months old with another set of G670's. That was 2 years ago. Don't know where the OP paid $1,180(rip off) for a tire. But mine cost me $524.30 each out the door, mounted, balanced and taxes.
Before the G670's my MH had Michelin XRV and I had 2 zipper blow outs with them before I replaced them at 6 years 8 months old.
One of the flats was a right front. No damage but I did use the Michelin video on hitting the gas when the big bang happened. I went straight and no problem controlling the steering. Or maybe my Safe-T-Steer helped.
