Tyre Choices

[celox]

I'm wondering what tyres are best for sprinting, standard road tyres eg. Eagle F1 or semi slicks eg. Toyo R888/Yoko A048 etc or is it down to personal preference.

Do semi slicks get chance to warm up enough with only 1 lap?

what class are you in?
cant use semi slicks in the road going classes, just the tyres on list 1a in the blue book (page 200ish)
the eagle f1's have quite a reputation as being one of the best road tyres and will be far superior to any semi slick in the wet

I had put myself down for 3c (modified production) which was a mistake as I haven't got a roll cage, but the other groups are 'road modified' and was told in the 'road modified' groups I could run a 1a or 1b tyre without the need for a roll cage providing the interior of the car and all trim was still in place, which it is.

I'm hoping i'll be able to change into the road modified group on the day.

i guess it depends on who is organising the event
in most regs i have read it states that any car in the road going classes must use tyres from 1a but having said that, just looked again at the regs for the sprint next weekend (aintree) and it doesnt state either, just that they must be road legal

It took me a while to find this info out and got most of the info from Steve Walker and Paul Parker.

just had another look and it is actually in the blue book, page 320 -

11 - Regulations for roadgoing production cars and roadgoing specialist production cars

11.6.2 - Tyres to R 3.1.1 List 1A

Using the Eagle F1's and going to contact the events secretary to change my group to 1B.

Thanks for your help.
