fine in a f1 racing car when your bums milimeteres of the tarmac but a total waste of money in a standard road carload of rubbish that in road cars and bikes...i measured my bike tire one summer morning before a ride out and with normal council estate air it only increased pressure by 3 psi on a hot afternoon with sticky tires....snake oil imho but having said that if someone buys it and uses it then that's fine too![]()
