There comes in time in most of our lives when we get a puncture in one or more of our car tyres. This can be frustrating and costly if it is in the wrong place. Many tyres can be repaired if the puncture is in a certain position otherwise it means that you will need to replace the tyre. If the tyre does not have much tread left on it, then it is worth considering if it may be more cost effective to actually replace the tyre anyway instead of repairing it. You can also get something called tyre form which when filled in to the tyre, expands and makes a seal over the puncture. The tyre can then be inflated and driven on. If you are using this type of foam check on the label as to how far you can drive on it and what maximum speed it recommends you drive at.
