I've usually had very good service from Michelin tires, but I haven't had good luck lately. With tires in general, in fact. We had two different sets of Michelin Latitude Tours put on our MDX before we tried a different model -- the Primacy MXV4. The Latitudes would never balance. The Primacys are better. Not perfect, but pretty good. Due to all the trouble we had with the Latitudes on the MDX, I put a set of Firestone Destination LE2s on the CR-V I used to have -- and then put on a SECOND set of them after the first set wouldn't balance. I was sure it wasn't the car, because the Michelins that came off were good. Even the second set of Firestones wasn't super...just livable.
The Ridgeline has the LTX M/S -- the OEM tire. The original set lasted about 80,000 miles, and this is the first replacement set, with about 20,000 miles on them. Fortunately, they're balanced pretty good and I have no complaints from them. They have some super light weather checking on them, but that's likely from being parked outside all day in the Arizona sun by my brother. It now stays in the garage, so any ozone influence will stop for the most part.
Our MDX will need tires in another year or so. The Primacy MXV4s have about 30,000 miles on them, and I'll look to get about 40k before replacement. Not sure what I'll put on. I'm not as strong on Michelin as I once was, but I'm also not strong on Firestone, either. Both could have been an unlikely fluke for us...who knows. Honestly, I think the Destination LE2 would be a great tire for the MDX, but I'd have a hard time convincing my wife, due to all the frustration I had with the two sets on the CR-V...
