I would guess the wing has minimal impact on rear tire wear. there are probably two main factors. The first is that it's a rear wheel drive and upon even moserate launch there will be a bit of spin as the tires grap, and depending on the amount of torque that would increase the spin and consequently the wear, which is why the fronts on my front drive car have always worn faster that the years.

The second and probably most influence would be in the rubber compounds of which the tires are made. Since their UHP tires, the compound would be closer to winter tires, that is softer so that at high speeds the rubber melts a bit to get sticky at high speed cornering, and therefore the constant melting on tire temp increases the more wear you get.

That's why I'm going to the Conti DWS's as it's not a super high perf tire, but a compromise for better wear, but one that since I don't push the NA all that hard won't hurt me, yet when I do won't punish me. It's a good compromise for me.
