The OEM tire on my 08 looks to be good for another 2-3000 miles - its got 6600 on it right now. It might make 10k.
Car or MC I've never had decent tire mileage with Pirelli. Maybe the newer car tires are better. I bought a set of Pirelli's for a 64 VW that were sport car rated and were supposed to be a 40,000 mile tire. I took them off at 30,000 miles so they wouldn't pop. Got a set of Goodyear sport rated tires after those and they went over 70,000 - not bad for a 50,000 rated tire. And I beat the crap out of them on hard mountain roads.
