When buying new boots recently it occurred to me that the original 'cartoon' spare tyre is the same age as the car (or older). In this case, 23+years. I have only had recourse to it once in that time, about 10 years ago. Do those skinny tyres have the same, or similar, life expectancy/limitation as the four corner boots? Obviously, it is not subject to either road impacts or UV exposure. It is however at a much elevated pressure.
I'm inclined to replace it, in which case I would prefer a 'real' wheel and tyre. Has anyone got one like this, 'Crown' I believe they are called, size 15" in acceptable condition, which I could buy?
Derek.
