Duro Wildlife Leopard vs. Duro Razorback
Hey, I got answer from DURO (Hwa Fong Rubber)!
Both tires have (as we all thought) the same geometry and pattern. The only difference is the used compund. The Razorback therefore has more wear resistance and less weight.
When the numbers I find are correct, you can save about 240g rotating mass by replacing the Wildlife with a Razorback (24x3")!
Seems to be a great tire!
