Installed these at 42,000 miles on 2008 GMC 2500 Duramax to replace the factory originals Bridgestone Duravis M700.
Original tires just lost cross-tread, so I replaced them because of winter weather is approaching. Still had a few thousand miles on them if used on dry surface. I towed a 13,000 lb 5th wheel camper for 10K miles out of 42K on those tires. Mostly highway.
First day driving on Michelin... what a difference! Ride is much more responsive, easier to maintain lane on highway, much quieter. It poured rain most of the day and tires performed superbly. No hydroplaning, no spin during quick starts, precise handling.
The ride appears to be softer then originals when going over road imperfections.
