I'm considering replacing my worn turf tires with tractor-type tires like those on Dixie Choppers. I'm thinking they will be less likely to spin and damage the turf. Also, I'm thinking they will hold the hills better. Any recommendations on tires for a QuikTrak (and possibly) a supplier? Also, the new QuikTrak has bigger tires than mine (I have an older model). I asked my dealer if mine could be switched for the bigger ones. He said, "Sure, but you won't like the cut." I'm wondering if with some adjustments to the deck, he could be wrong. Any thoughts?
