Had a blow out on my truck right rear last year. Destroyed the fender and exhaust system. Would take some really strong steel and probably reinforced under side of slide and inside of fender skirt area to prevent damage. But all that would probably interfere with slide operation. And probably be expensive also. High quality tires, not too old, well taken care of, and a TPMS is the best option. Although a high quality tire can also blow, it seems the majority reported on RV sites tend to most often be from brands previously noted for that problem. IMHO of course.
