Neither do I - which is why the car isn't getting garaged over winter; it will be used. And the wheels aren't coming off because I don't want them to get dirty - they're coming off because in the long run it's cheaper to have two sets of wheels with two sets of tyres, than it is to keep paying £50/£60 to have the tyres swapped twice a year (wheels were £78 - that's cheaper than swapping the tyres on in Dec and off in March - and if I keep it any further years, it's cheaper still)
