List of race classes using 15 inch slick tyres?
Ok, 13 inch slicks are commonly available secondhand, as are 17 inch ones due to BTCC, formula renault and formula ford.
Michelin make 15 inch slicks, as do avon I believe and they cant just be for the trackday market?
Does anyone know of any classes which use 15 inch circuit (not hillclimb) slicks?
Cheers

The new Clio cup cars use 17" now. It's very hard to get hold of 15" slicks. If you do they're often old and hard 
I've given up and will only use 13" slicks and 15" r888s

Www.pickuptruckracing.com
Ticks all the boxes. 15 inch, avon tyres, slick, 8.5 wide tho. Loads of them racing.
Circuit racing, mostly oval though if thats a problem. They do a few other circuits tho. Croft, brands hatch etc

8.5 is probably too wide
I have a nova 1600 16v at the moment which I stopped developing when i decided to do the locost instead, but its in a nice track spec and I enjoy
doing trackdays in it. Im fed up with forking out 50-70 a corner on tyres and would like more dry grip. Road tyres on a wet track dont wear badly, but
in the dry they get far too hot!
Ideally I need something akin to a 195/50 road tyre, or drop to 14s and go for 185/60 or something.
Im going to run 13s on the locost for this very reason (amongst others)

What's 8.5, 210mm? Not hugely out. I was given a set of weller wheels they used to use racing, fitted with worn out 235 tyres. Used on track
days i think. So i wouldn't think 195 wheels with 210 tyres would be too bad. Its only 15mm

its not the wheels, its the arches 195mm will go, 205 wont! both on a 6J rim.
8.5 inch widh slicks are going to be 210+ and slicks tend to be larger than they say.

I bought ten 15" old Clio cup slick tyres for my Clio last year,still using them,I only paid £15 each for them,they are Michelins so new are
around £150 each,but because they have been used the grip levels from them are not great,but as I am not racing and only trackdays it does not matter
so much,but I find I get better grip from new R888 tyres.
