Just a quick question as I have searched the net and can only find out that the NGTC BTCC cars are now running 18" centre lock rims with 245/650/18 tyres.
What width are they though as this is not published anywhere. Can anyone tell me definately what size they are and not an assumption because of tyre size.
Do thay have a choice of width?
Any light on the subject much apreciated
