My existing Michelin 255/80x22.5 tires are 8 years old and I am replacing them. The Michelins I have on now I have been pleased with. When I bought them 8 years ago they were 2400 dollars out the door...
You have size that is used commercially, or at least my 12R22.5 were. You can find sizes used by commercial trucking in 2 years age with 20+ percent thread left. Bill's Tire in Pacheco could find them for me for $100-150 Tell Bill that Kris send you.
