Yeah, Michelin Tires are VERY over rated. I've worked on Big truck most of my adult life, I worked for Kenworth trucks for 20 years alone. they have always had issues with drying out and sidewalls cracking....for years. I don't understand why people still brag on them. They will go the miles, I'll give them that. But you need to run them bald in 2 years or less, on a big truck it's possible, on a RV, your simply not gonna. I don't know any RV'r that runs 150-200k in a yr or 2. My tire guy quoted me $1700 for 2 Michelin Steer tires. Is that crazy or what. I'm getting 6 Toyo's for $2600. And that's even high......to me.
