Hi Does anybody know where I might be able to get an Avon CR500 175/55 R13 please? I know they were discontinued by Avon several years back and replaced with the ZZS but I have a set of CR500's on my 360s which are all fine other than the front driver's side which is worn on the inside. I've been advised that if I change the front, I should ideally change all tyres to the same type or, at the very least, have the same tyres on each axle. I know it's a long shot as they haven't been manufactured for quite a while but I wanted to see if I could get a CR500 before moving on to buying multiple tyres. Any advice or thoughts on replacement would also be appreciated - I haven't had my Caterham long so would welcome advice from those with experience/knowledge Cheers Mark
