Wednesday's Watchdog programme (BBC1 Wednesdays 8.00pm) carried a report about people's concern that new cars, on the whole, are no longer supplied as standard with a spare wheel. Instead a 'tyre safety kit' is provided, which entails injecting the punctured tyre with a sealant and air mixture, sufficient to get you home to arrange for a repair. We were told that some tyre fitters are reluctant to repair tyres that have been injected in this way, as the sealant is difficult (aka 'time consuming') to wash out and the customer is usually informed that he needs a brand new tyre! A representative from the Motor Manufacturer's Association claimed that, in an effort to produce vehicles with greater fuel efficiency, spare wheels are now no longer supplied as standard as these can weigh 20 kilograms (rubbish!) and can therefore compromise a vehicle's mpg. Never mind all the inconvenience (not to say danger) of trying to operate a tyre safety kit for the first time in the wind and the rain beside a busy road, why should a small repairable puncture be ignored in favour of a brand new tyre? (Cynics can ignore this rhetorical question). Apparently you can specify a spare wheel if you want one, but the well in which to keep it stored out of the way is rapidly becoming a thing of the past. Personally I wouldn't dream of not having a spare wheel in any car I was driving. Has the world gone mad .... yet again?
