Your correspondent RW, from Braintree is right to be disappointed with the lack of a spare wheel in his Ford C-Max and I am astonished at your apparent sycophancy to the manufacturers who perpetuate this scam. I was recently astonished to discover that even a car as fully loaded as the Audi RS6 only came with a notoriously unreliable "do it yourself" puncture repair kit. This is not just about getting you home, its also about keeping mobile whilst the damaged tyre is in for repair or replacement. You are not convincing anyone that runflats are all about safety. Presumably sales of these very expensive tyres have soared and no doubt car manufacturers are scooping worthwhile discounts or maybe even rewards from the tyre companies for fitting them. Here’s an idea. Why don't manufacturers simply own up that that this is really about keeping costs down?
