I'm getting new tires on my 2002 Newmar Kountry Star 38Ft Diesel Pusher this spring. There are Firestones on it now, that have a build date of 2008. I went to a commercial tire store, and asked about tires. I have 275/70R/22.5's now. He sells a few different brands, and first thing he said was that Michelin AZA2's are the way to go. I am using the FMCA discount, getting 6 for about $3600. Balanced, long stainless valve stems, installed, and old tires taken away. I don't like spending money I don't have to, but tires are a very important safety item on any vehicle, but especially on an RV with all the weight. If you look at almost any high end RV, they have Michelins on them. Time will tell if I am making the right decision.
