This what you are seeing.

Options:
1. Get an adjustment for your throttle pedal (connection between brain and foot) to modify wheelspin frequency
2. Retain driving habits and try AA/200 tyres - I suspect they will wear out in less than 2 years OR they may go harder faster
3. Sell car and purchase bicycle
4. Follow someone else's suggestion

Seriously, you will need a massive wide tyre to provide grip for the torque you have. Put those wider/grippy tyres on the car and other parts of the driveline will start failing.

I have had NT05 on my car and did not like them as they went hard after a year (I cover ~20K klics per year).

Best option I can suggest is Dunlop Direzza Z3 but not sure whether they are common in the US. I've used a couple of sets on my car now.


What is happening is that the MPSS are being heat cycled. Everytime you spin the tires. The tires goes through a heat cycle. Enough heat cycles will cause the rubber to get hard and less grppy. This will happen to ANY tire. New MPPS. I can go about 25 minutes on the track before they start losing grip and become greasy. After about 5 trackdays. The same tires will go about 15 minutes before they get greasy. The tread wear of a 200 tire will have more grip but shorter tread wear then a 300 tire. A 300 tread wear thread will have less grip but more tread life then a tire with a 200. Most cases, a 200 tread wear will heat cycle faster then a 300 tread wear tire.
