Leak pudding

You are mention runflat tyres to avoid the danger of changing a wheel on a dangerous road or motorway hard shoulder. But I have not heard you mention the product "Puncturesafe" that instantly repairs all punctures as you drive. "Puncturesafe" automatically coats the inside of the tyre and remains fluid to instantly fill any puncture the moment it occurs. I was sceptical when I first heard about this, until I heard that they had the contract to supply it for the Royal Mail's 32,000 vehicle fleet. What is your opinion?

Bikers use a couple of products like this because a sudden deflation could have them off and dead. Caravanners have used them for years. Feedback tells me that some are better than others. But obviously tyre manufacturers would not have spent millions developing runflat tyres if products like Puncturesafe were the ideal solution. What would have been the point? I asked Michelin and the answer was that Michelin does not approve of this type of product.
