Just looking at options for track wheels and tyres for a 172 Cup. Track tyres aren't available in a 195/45 16 as far as I can see. I've been looking at 195/50s instead. It occurred to me I could drop to a 15" rim instead, where track tyres are both cheap and plentiful. Any reason why this is a bad idea please?
