I have not heard of these, but I am currently running Cooper tires on my 95 Yj and I love them. Mine are Discoverer S/T. The S/T means soft traction not snow traction like some people think. They are not a full blown mud tire, but they are an extremely aggressive all terrain tire. I have over 25000 miles on mine and they have less then 1/32 of wear. I live in Northern East-Central Alabama, and we have a lot of clay gumbo mud and these tires work like a charm.
