Booked on a trackday and the weather is looking clear but cold -7 !

Is it worth taking the R888's off and putting road tyres on ? Or, is it easy to get heat into R888's ?

Thanks.

It should only take a lap or two to get them warmed up (also use the brakes to build up heat in there) but there is some info somewhere about the dangers of using 888's in cold weather due to them not designed for extreme cold, think there is a risk of a blow out in extreme cold (could be wrong).

The warning that comes with the tyres mentions that they shouldn't be stored in sub zero conditions whilst being on a car. They can crack, which could lead to a blow out later on.

I am pretty sure that they will be fine as long as they are gently warmed up.

Hi Dan

You should start to feel the tyres get better after 1-2 laps at Silverstone so long as it's dry, take your time on the first couple of sessions as you get used to it but it will be quite noticeable as they get stickier. If it's wet or even just damp they will still work but they will be much harder to warm up properly.

What date are you there?

Hi Steve,

I am there on 3rd Dec.

I have not done a trackday for a year, and will be nice to get back on track.

The R888 are a little low on tread (2.6mm), just hope it's dry !

Disagree - tyres heat up mainly due to distortion in the tread. With less tread blocks and so less tread to move around and heat up, they will heat up less quickly than road tyres.

Slicks take longer again to heat up.

their semi slicks so do have some tread + much softer compound that road tyres so should heat up faster

In my experience, It depends on the weight of the car.
A 7 will take several laps to get to the low side of optimum temp.
An E36 BMW will take a lap with newish tyres. As yours are down to 2/32" it may take 3 or so laps as the tyres have been through many heat cycles already and may be past their best.

The tyres have not been used on track before.
I have only used them on the road.

compound comes into it significantly - in general 888s will be softer than road tyres, so will warm quicker - same with slicks, depends on the compound...

Dan, I'd stick with the 888s unless it's severely wet which is pretty unlikely, the current forecast shows cold and clear for the latter part of the week

I think I'll be instructing on that one so come and say hello and book a session.

Wow. I'm amazed at the number of people here advising to ignore what Toyo say regarding temperature. It's looks fairly black and white to me. If it's less than 0 degrees then don't use them. How quickly they warm up is irrelevant if the cracks form in the first half lap.

I can see what you mean, but if there are people who use them in cold condition and are fine ??
