I haven't owner this tire but friends of mine have and they were decent tire. Similar to the BFG A/T KO but a bit cheaper. Personally I prefer the BFG AT KO2 released in the last year or two. General has been bought some time back by Continental and from what I understood is that Continental likes the brand and even this model and pumping money into General. I have continentals on my Envoy and they are great so far at 40k km.
