Hi,

I'm building a nitro racer from scratch to compete in the formula schools competition in the uk.

I wonder if anyone can tell me the outside diameter of various wheels and tyres which would be suitable for tarmac racing.

I'm after something about 95mm (outside diameter of tyre), I have been told that 1/10th are usually about 65mm (which is too small) - can anyone tell me what the outside diameter of 1/8th tyres is (the ones I have seen all seem too big but maybe that's because they are on buggies).

Basically I want to be pointed in the direction of cheapish wheels and tyres about 95mm outside diameter.

Thanks in advance.

John
