Anti-theft Tyre Pressure Monitor - Indicator Valve Caps with Lock Nuts and Spanner - 35 psi - 2.4 bar - silver

pThese easy to install tyre pressure indicator caps, constantly monitor your tyre pressure with clear bright colour indicators. When the tyre pressure monitor is firmly screwed onto the valve stem of a cold tyre that has the correct pressure, the see through dome at the top shows green. /p pIf the tyre loses 3 to 5 psi of it's pressure, the colour will change to green and yellow and it is now recommended that you top up this tyre with air. If the tyre pressure drops by more than 6 psi, the colour will change to green/red/yellow. This indicates a seriously under-inflated tyre (and possibly a puncture) which should be re-inflated/assessed immediately. The spanner and the lock nuts have been provided to ensure the valve caps are anti-theft and locked securely in place to prevent accidental deflation. /p pThe correct tyre pressure for your vehicle can be found on the inside driver's door jam, on the petrol cap cover or in the owner's manual. The caps are made for a full range of cars, vans, motorcycles, bicycles, caravans and light lorries. /p pPhotographs and description in this listing only relate to the product sold by 24seven and fulfilled by Amazon./p
