To my understanding, the biggest problem with RV tires is not activating the oils within the rubber to keep the tires viable. Unlike our personal autos, which are driven nearly everyday, most RVs go weeks, months, or even longer without moving. This could wreak havoc with the tires, and cause early failure due to the rubber drying out. I move my rig every couple of weeks, use a spray-on tire protector, and sunshades to protect the sidewalls when not traveling.
Our first set of tires lasted 10 years, with only 40,000 miles on them. The sidewalls finally showed signs of drying out, so we opted to change the tires out at that point, before a catastrophe could strike.
