Yes, RV tires have a more pliable sidewall resulting in a softer ride and handling. Truck tires have a stiffer sidewall resulting in firmer ride and crisper handling. Also, a sidewall that is more resistant to cuts and curb rash. Generally, truck tires are more easily found when you have issues requiring roadside replacement. The truck tires I just purchase last October were more affordable than the factory RV tires I took off. I personally would be interested to see a side by side comparison of tire aging. Tested with tires that are covered when not used, and never run underinflated or overweight.
