I have a Nissan Micra, year 2002. The tyres on the car are Dunlop Sport 300E. I was checking the tyre pressures today and I noticed a nail in one of the rear tyres. It was stuck in between the treads, so it looked as though it was embedded quite deep in the tyre. But no air was escaping.
I took the tyre to Kwik-fit who looked at the tyre and said it would cost £15.99 for a repair including new valve and wheel balance. I agreed to have the repair done because I was worried that the nail might cause a blowout. When I mentioned this to the repair man, he said that would not happen unless the nail was in the tyre wall. He disappeared in to the workshop with my tyre and I couldn't see what he was doing, but I heard some burring noises and I saw him fetching some pliers at one stage. Now there is a rubber seal in the hole where the nail was.
I just wonder if this repair was necessary. If my tyre is a radial, then does this mean that there is some metal in the tyre to stop nails penetrating through? If so, then could I have just left that nail embedded there?
