Both of those tires are pretty hard and not very sticky for a Cobra. Coopers are 440 tread wear. Like rocks! I am going to bet my 20 year old Michelin Pilots with 220 wear are going to hook up better than new Cooper rocks. I would say they are in the 300 vs 220 when new. All depends on the condition of the tire. I have seen 4 year old tires cracking in AZ. All depends on the quality and the rubber they are using.
