NOW with a larger 400ml sealant bottle for even better car tyre sealing.
NOW with a Presta valve adapter so you can inflate nearly all bicycle tyres.
Millions of cars are now being sold without spare wheels, so owners no longer have the ability to change a wheel when they get a puncture. Instead, the car companies offer an aerosol sealant spray in a can – which rarely works: the sealant is too weak to seal a normal hole and the air in the can is insufficient to reinflate the tyre.
Or, the car manufacturer offers a kit with a compressor and a bottle of sealant. These OEM kits are usually very cheaply made – the basic compressor is not powerful enough and the sealant has a shelf life so that just when you need it, it will not seal the hole.
Then of course there are also millions of drivers who do not know how to change a wheel, or do not want to.
