At a campground this weekend I noticed a tire on my trailer had a small bubble on it. Trailer is 3 years old. Reckon it is about time I put some new shoes on it. Really thinking about the Michelin XPS Rib. I have heard some scary stories about the tread coming off a tire and it isen't pretty what it does to the underside of a trailer. If you got the Michelins do yall like em OK?
