Other than being sure there is enough clearance to use 15" tires instead of the stock 14" tires. Is there anything else I should be aware of that could cause a problem?
I did the same on my small 5th wheel.....went from ST205/75-14s (1750#) to ST225/75-15s (2300#)....works well, rides smooth. I was also near the top of my weight, now no worries
