Great points indeed. I am sure Stealth has something up their sleeve to address the duro Razorback supply issue. Yah, the Halo Contras and Wildlife Leopard are the same tread pattern, the wildlife has a softer compound than the Razorbacks, I compared them side by side. Also, the Wildlife Leopard did wear a little faster on the front, but not much. I can get 1500 miles out of Razorback on the front, got about 1150 with the wildlife leopard. I guess I am luck as I bought 10 Razorbacks for 250 bucks two years back. I am down to 2 left. Going to need to find something else, or go back to a motor tire and rim combo on the front.
