THANKS .will have a look on ebay and see what i can find...maybe its going to be cheaper and alot more straight forward to leave it alone and have a limited choice on tyres.....i take it that 18" rims are an 1980.s thing ,,as most bikes all seem to use 17" tyres.....saying that i have since found a pair of bridgestone bt021 for £199 for the pair ,..but then i get confused on the best tyres to go for..dont seem as easy as buying a car tyre when you just buy what you can afford..i seem to get swamped with questions and options for which tyre to go for..
