Punctures can work in one of two ways – either they instantly cause the tyre to ‘blow out' and it will need to be changed before you can drive; or they deflate slowly through a small hole. In the case of the latter you may still be able to drive the car, especially if you have tyre foam to hand that will temporarily block the hole until you can repair the tyre or replace it. Tyre foam is inserted into the tyre just like air and is completely legal. However, it is important that drivers don't assume the tyre foam will last forever – it is an emergency solution to a puncture. Euro Car Parts keep a range of tyre foam and tyre care products in stock and our expert team will be able to provide any additional information you might need if you have never bought tyre foam before.
