You go deep into a brake zone, hard on the brakes, firm brake pedal but the car keeps on going and doesn't really sow down.
PCCB is famous for this but I've had this happen on even my Carrera S running Pagid Yellows. I now brake earlier, less brake, hardly even get into ABS, just a tickle sometimes and no more " Ice Mode"...oh and my laps are faster this way. Safer too.

R888 is no where near as bad as you all make them out to be as long as you run low hot pressures...no more than 35 hot...I run 32/34 hot and not try to run them to the cords from full tread. I agree they are not a long living as RA1 but RA1 has been out of production for our cars something like 3 years now.
So far I'm liking the R888 a little better than MPSC in stock 19" sizes. This weekend at Sebring will tell me a lot more.

Why would ice mode be tire dependent? This is the part I do not really understand...
I have PCCBs, R6s, never experienced this. I've seen a Lotus go off and roll, supposedly due to ice mode as was discussed after the fact. Scary.

This is mostly for anybody who doesn't yet have dedicated track wheels, or only has 1 set. If you going to be doing this "track" thing for a while, and you really want to make your tires last, then first invest in a second set of track wheels. They will ultimately pay for themselves and give you a lot more options and flexibility to take care of your tires over the course of a weekend and a season.
Examples:
1. Say you show up for a 3 day weekend with a set of used tires and a brand new set. You can scrub in the new set lightly, then run the used tires for the first 1-2 days, then switch to the new tires for the remainder of the event. This allows you to NOT cord the used set by inducing too much outside or inside wear. So by not using them and flipping them when you get home, they are still available for duty on the next weekend.
2. The wear rate of front is much less than rear, so having a second set of rears gives you the option of completing wearing out your most used set a the track, then switching to the next set of rears. This also increases your total use/$ spent, because you then don't have to dismount the used set for a new set prior to your next event, because you are afraid you won't have enough rear tire for the weekend. Tires you don't cord at the track almost never get re-mounted up for a "1 or 2 day" event to cord, they just sit in the garage. Drive them until they totally heat cycle out (R6), or they cord (RA1/NT01).
3. As discussed, Flipping tires extends the life of tires by as much as 20%, and since you cannot swap from front to back (like I can do on my M3), then you need to do everything you can to extend tire life. But by having a second set of wheels/tires, then you don't have to worry about flipping tires at the track, you can do it when you get home before your next event. Just swap side to side while at the track. Been doing this for years and it works like a charm.
4. Different tracks wear tires differently, so in the case you go to some events where you get erratic wear, or it takes you a day or two to get your pressures right, you then don't have to worry about destroying a single set of tires for the weekend. Some tracks/surfaces can vary as much as 1-2 degrees in terms of camber requirements, and we obviously can't change alignments on the spot.
5. Anybody with a .1 and steel brakes has zero excuses not to have 2 sets of OZ Allegeritas, they are dirt cheap. Everybody else is kinda screwed, $$.
The list goes on and on, but like I said, in addition to all the items mentioned, a second set of track wheels is the ticket. I know, it sucks paying for a second set, but find the most affordable second set you can, mind your tire temps and pressures, and have some fun!

Mvez, you left out....you need a truck and trailer to do any of this. I don't have the truck and trailer just to haul a car around to the track...so I drive to the track, have fun, drive home.
