These wheels and tyres are for sale on Ebay. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=015&item=250027376127&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1 So, I contact the seller asking how many millimetres of tread the rear tyres have got on them. His answer is "I'm not sure, how about I send you a photo?" I say a photo is not much use, I'd rather he just measure them and tell me. After all, it's not difficult, and I like to know what it is I'm thinking of buying. His reply is "They've got a fair bit of tread. Measuring them isn't easy if you have got the tool to do it". WTF is wrong with people?!
