I also ran one set of Michelin AS3, which on that car had a noticeably more abrupt breakaway (not scary, but noticeably different) than the T1Rs and my current Pirelli runflats on my M240i. I bought them because they were reputed to be much less noisy than the original F1 Supercars, and was delighted to find they had less traction as well so sliding the car was easier). For what they are worth, the breakaway characteristics of the Pirellis are similar to an extreme performance summer goflat tire, the Toyo Proxes T1R.

My comparisons are to another car (C5 Z06) which is lighter and has much wider tires, so I'm not sure they are valid. My experience is that the Pirellis lose traction gradually and predictably. What you wrote sounds suspiciously like 'I ran way too fast into a turn, scared myself badly and blamed the tires rather than the driver.' I'm also puzzled that you think your fact-free opinion would change the minds of such people. I'm puzzled that you appear to be concerned that a tiny minority of 2-series drivers think the Pirelli runflats are an acceptable tire.

There are plenty of reasons to have RFT's, performance is not one of them. I played with Pirelli pushing car hard once, that was a mistake. If you are using 50% of the cars ability on the street only.accelerating a few hard times straight.sure.īut pushing in mtns and light track work, PS4s is a 10 street tire, run flats maybe a 5. My new Pirelli run flats, and wifes Conti run flats were crap, brand new. I feel like folks are convincing themselves that run flats are even in same world as Michelin PS4s.
