TYRES - Is this likely to be a hornets nest? You blokes who fit like 26x12x12 or 23x10.50x12 etc (to the back). Considering that CCs do not exactly do 100mph across the paddocks, do you just fit them to the standard 6.20x12 rims, or do you bother using wider rims? Or maybe my question should be, do 122 & 123 have a different width rim to 71 &102?
