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...
I replaced my 255/80/22.5 Michelins with Bridgestone 265/75/22.5 tires. Very little difference in revolutions per mile so no recalibration of any kind needed. No noticeable difference in ride or handling.
