Thanks, i discovered that the size of the rims in btcc 98 was 19" so the dimensions of the tyres could be like 225/35 or something? please correctme if im wrong!matt21 wrote:In 98 BTCC was driving to Super-Touring (Class 2) Regulations.
Max tyre width was 9 inches and the overall diameter 650mm.

Ok, i thought the sizes had the same notation has the street one, anyway now i will be able to get the tyre ruber height by substractin the 19" in cm of the rim from the 65 cm total tyre diameter!matt21 wrote:Something like this if you compare it to seizes for street tires.
In racing you have a different notation.
