[QUOTE="RMT, post: 206906, member: 6069"] I like the 888R's. Great track tire though I am not as comfortable in the wet with the 888R's as the Cup 2's. When the Cup 2's still have adequate tread left they actually have great grip in the wet, provided the water is not ponding. In terms of tire wear on the Cup 2's, I don't think that there will be too much of a difference between the Porsche and the C8. My PDK Cayman S is around 3000 lbs with 235's up front and 265's in back. With my 3400 lb C8, the C8 is about 13% heavier. With 265's up front, I will have added about 13% more tire width than the Cayman. With 325's in back I will have added about 23% more tire width than the Cayman. Assuming roughly the same F/R weight distribution for both cars AND IF I can get the suspension set up right, front tire wear should be about the same as the Cayman due to the proportional increase in tire width to compensate for the extra weight. With the same proportial adjustment plus an extra 10% in the rear tire width I am hopeful that this will compensate somewhat for the increased torque and give me about the same rear tire wear as the Cayman also. Unfortunately, all speculation and calculations until the rubber hits the road! [/QUOTE]
