I swapped the tires on our 3220BH Passport from 205/75/14 to the 215/75/14 that were on our 26BH Grey Wolf that we were trading in. The 205s were wearing ok but since the 215s were only a year old and had another 110lbs per tire load capacity I figured why not. It may not be a huge upgrade but it was "basically free" since after we had our price negotiated I told the dealer in order to do the deal he had to swap tires also. Our 3220BH is pushing 7400lbs and after about 1500 miles so far this year the tires are not showing any abnormal wear.
