Has anyone heard of or have foam sprayed in your TT tires? Dealer convinced a friend of mine this is the way to go because he will never have a flat tire.
I think the idea is using a product similar to fix a flat, which is supposed to spread over the inside of the tire, then seal a punctures when it happens.
I think this is where theory hits the cold light of reality.
I would be surprised if it was effective for more than a few months, otherwise ever car company would be bragging on their puncture proof tires.
