I have been offered a cheap set of Continental TKC80 Twinduro tyres but the rear tyre size is 140/80 18. The Twinduro is a on/off road orientated tyre and might be useful for mixed road/trail riding. Does anyone know if this tyre will fit? I am using Michelin AC10 with a 110/100 R18 which is smaller in width but taking the aspect ratio of the wider tyre the radius is almost the same (I believe).
Just in case the model makes a difference, my bike is a 93 White tank TTR250
