spirited miles
I've only gotten 500 miles out of these tires as they've been used on my track wheels and are never used on the road. They take a couple of laps to warm up, and you won't want to use them between the months of October & March, but once up to temperature they easily exceed the grip of my normal Michelin PS2s on the track although this extra grip comes with a price that means you don't get as much progression before you lose all grip.
I've done both circuit days and airfield days, and I got 4 circuit days out of them and would have gotten more had I not done an airfield day in them. The airfield day destroyed the tires within 3 laps - mainly due to the nature of the surface (i.e. high abrasion concrete for airplane landings) compared to treated tarmac on proper tracks - and that they are a soft tire.
In the dry they are great - not as good as proper race rubber - but you can use them in the wet, as long as you're careful.
Don't know whether the previous reviewer used them on a proper track or not, but I'm not surprised they were killed on an airfield surface. My PS2s only last half a day (4 sessions) on an airfield and they're a harder compound.
