A year ago I bought a set of 275/65R20 Goodyear Wrangler All-Terrain Adventure with Kevlar Pro-Grade tires. They have been excellent. Quite, good ride, good wear, excellent in the snow, rain, dry, etc. I have been very impressed and will likely get these again.
I had the OEM Michelin tires and they were good too but they did wear out pretty quickly.
