I'm going to continue to use Michelin on my class C. I've always regarded them as a cut above-better production tolerances, rounder, less runout, need less balance weights. First rate as far as sudden failures. Don't want tire problems on motorhome most inconvenient or worse. At one time putting Michelin tires on a vehicle was almost a revelation.
I think now there is less of an edge. Other brands no longer make me want to get them off the car ASAP. My Frontier came with Yokohamas which were fine on that. My '15 Accord came with Goodyear-totally impressed butter smooth and quiet at 80-90 MPH, nice sharp handling, no negatives I can find. Would consider them again.
