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...
Firestone maybe. In the same boat here. I saw a lot of Firestone on the big trucks. A lot of people here so you should get a good clue of what is out there.
