I just looked at these. Some people rave about them. I read that the Cobra's durometer is harder than the Ripsaw's, the lug height is kind of decieving the 1.352 height is only determined a the top of the molded boss which is a protruding tip. The entire lug is not that height. Since I just blew my single ply @ 5300 miles, I opted for a 2 ply 1.250 Ripsaw 2.86 pitch for my 09 doo. My needs are little different that most. The Cobra lugs also do not deflect as much due to the harder durometer. AT LEAST that is what I had dug up while doing my research. The lug form is a little different also.
