Yup, totally done in! The white patches on the lower parts of the picture are the casing fabric starting to be revealed because the rubber has been completely worn away! Indisputably illegal! I'd take bets it's been used on a front wheel? I'm not a lover of spacesavers but hate no spare and a can of gunge even more. I also would not mount a spacesaver on a front wheel of a front wheel drive vehicle because of the handling of course but also because of the difference in diameter causing the diff spider gears to work overtime.
By the way, now my old SEAT Cordoba has gone to the happy hunting grounds I've just discovered the space saver it came with, and quickly replaced with a full size spare, at the back of my garage. It's never been on any vehicle and is absolutely pristine having been stored in the dark at the back of a nice dry and cool brick built garage. Anyone got any idea what I might ask for it?
