Changed to Toyo's on front after Michelins (3rd set) again had extensive rivering. After many alignments, balancing I could only get approximately 60,000 miles or less on fronts. I replaced Michelins with Toyo's 154's. 3 years and 35,000 miles later they still look great and ride good. The Michelins on the rear are 6 years old and have cracks on sidewalls (third set but the 1st that were over 4 years old). As of this coming Friday I'm having 4 more Toyo's mounted on rear. My coach has 204,000 miles. Just my experience.
Hope this helps.
