Does anyone use Circuit 'wet' tyres?

They are SUPER soft. Maybe too soft? They soon get chewed up in the dry, but maybe not too bad on a short hill and a light car?

We have some of the excellent 15inch Dunlop wets part-worn that could be tried....

I use Dunlop CR311 in X22 super soft compound. Works fine but could use a softer compound on the hills. On a sprint at say Pembrey on the second loop they are just starting to go off so as an all round tyre pretty good.

They are also cheaper that 'proper' slicks at about half the price (approx £500.00 a seat as opposed to £1000.00 a set!!). That said I am told that Avon radials in a proper hill climb compound are worth at least a second over a rally slick. I have a set of 8j rims here ready to check this out but that will be next year now. I'll let you know when I do!

As I under stand x22 is a wet compound, they normally cut them in to full wets. I use them un cut as wets and they are fine as long as there is not too much standing water. It's not unheard of for the Golf to be the fastest car on circuit in the wet on x22 slicks! Great feel and confidence from them.

Used -1 to -1.5, about as much as you would want to put on a crossply but less than a radial typically uses

I think that works ok on a Caterham, but hatchbacks lean a lot.....

My ibiza used to fold over the outer edge of the tyre even with some negative camber on. Discussed it all with paul smith at bmtr at the time (avon guru) and only conclusion was that radials would suit my car better. And have gone much faster on them than on avon hillclimb crossplies. Go figure....
