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...
Mine were 275/70R/22.5, I bought Hankooks that were less than $400 each mounted, balanced and tax out the door. Had Goodyear before those and the Hankooks were much better in ride and performance.
