Motoring organisations say that punctures and other tyre problems are only next to battery issues in the top breakdown causes. Car makers usually only supply temporary puncture repair cans, or “space saver” wheels. Some manufactures will sell “proper” spare wheels as add-ons. Personally, I think the old spare wheel saves on all the stress of trying to find a tyre fitter – when the temporary repair is useless –    on a sunday evening during a driving lesson through Glasgow Westend, who just happens to have your size of tyre and wont cost you a truck of money to come out and solve the problem.
