Welcome, David Kirk
I find that the wide wheels common on modern garden tractors tend to rub on the mower struts and other implements and prevent a full turning angle, so I got a pair of original narrow rims for my I5, and to complete the luck, Jim fitted them with tall 3-rib agricultural tires. No more rubbing, and no more nose-down stance when I'm wearing the big 'ol balloons in back. My property has thin turf over hard glacial till, so no worries about rutting the lawn!
