Four screw-on caps that show you a flat before you feel it.
Underinflated tyres cost you fuel, wear the shoulders out early and are an easy MOT advisory. These caps replace your existing valve dust caps and change colour the moment pressure drops below the safe threshold, so a walk round the car tells you everything a gauge would.
- Green to red indicator – readable at a glance, no tools and no app
- Screws straight onto a standard Schrader valve in seconds
- Nickel-plated brass with a rubber seal, so they stay put and stay sealed
- Anti-explosion vent design releases safely rather than blowing off
- Set of four, enough for one car
Fits standard Schrader valves on cars, vans and trailers. Set of 4.
A two-minute fit that quietly watches your tyres for the next few years.
