The less time spent on the roadside, the better – that’s the thinking behind the £59.99 ContiComfortKit (pictured). It repairs and inflates punctured tyres in a fraction of the time it takes to change a wheel. If you prefer to replace the flat rubber, buy an extendable wrench (under £10) and a 12V powered jack to make the job easier. Our favourite is Maplin’s £50 Electric Car Jack.
