Use the values printed on your tyre or measured with a suitable gauge. TyreDeck explains the result but does not certify a tyre, wheel or vehicle as safe.
What this tells you
Use the full fitted cost where possible: tyre, fitting, balancing, valves, disposal, delivery or call-out charges can change the real total.
Use it properly
Include fitting, balancing, valves, disposal, delivery or mobile call-out where they apply. Compare the same number and specification of tyres.
If you see a bulge, exposed cord, serious cut, rapid pressure loss or a visibly flat tyre, avoid unnecessary driving and arrange a competent physical inspection.
