I have some Carlisle tires on my little Kubota BX-23 and they've worked well. They sell a 29" tall tire (29x10.5x15), the "Trac Chief", that has a great load capacity...way more than the TC can handle...but I like the durability that imples. I pretty much hate the stock TC Industrial (R-4?) tires for what I do. They suck for traction in the mud and I don't find them impressive in the snow. After looking at the Denman web site I didn't see much in the way of 29" tires for a 15" wheel but maybe I just missed it.
