It almost would seem that the tires that used to use would be better than the ones they use now. I have the Carlisle Turf Savers, I believe, that have the sort diamond shaped treads. I think the older ones with the sort of peanut shaped treads would be a little more aggressive. Personally, I would love to find one about an inch or two taller (now have the 24's) to see how they would fit and work.
