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
Cost per mile is a planning comparison based on your mileage assumption, not a promise of tyre life.
Use it properly
Use total fitted cost and a realistic mileage assumption. Run more than one mileage scenario because tyre life is not guaranteed.
Safety note
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.
