Cars, light vans and light trailers must have at least 1.6mm tread across the central three-quarters of the breadth of the tread and around the entire circumference.
TYREDECK CHECK
Check your tyres.
Know what needs attention.
Work around all four tyres and record tread, pressure status, visible damage, wear, age and TPMS warnings. TyreDeck will flag what deserves attention without pretending to replace a physical inspection.

4-TYRE HEALTH CHECK
Start with what you can actually observe.
This tool is for cars/light vans and uses 1.6mm as the UK legal tread threshold. A green result means no immediate issue was flagged by your answers — not that TyreDeck has certified the tyre safe.
UK ROADWORTHINESS BASICS
Facts TyreDeck uses in the checker.
Tyres must be correctly inflated to the vehicle manufacturer’s specification for the load being carried. Use the vehicle handbook or vehicle data, not the maximum pressure moulded on the tyre sidewall.
Tyres should be free from certain cuts and other defects. A current MOT does not remove the driver’s responsibility to keep the vehicle roadworthy between tests.

MOT
MOT tyre check
An MOT checks tyre tread, condition and other tyre requirements, but a current MOT certificate does not guarantee that the tyres remain roadworthy until the next test.
Check this issue →PROBLEMSPunctures and slow leaks
A puncture may be repairable only after the tyre is removed and inspected. Sidewall/shoulder damage and damage caused by running flat can rule out repair.
Check this issue →SAFETYSidewall damage, cuts, bulges and cracking
A bulge, exposed cord, serious cut or rapid pressure loss is not something a web checker can clear as safe. Avoid unnecessary driving and arrange professional inspection.
Check this issue →MAINTENANCETPMS warnings
A TPMS warning is a prompt to check the actual pressure and condition of every tyre. TPMS does not replace manual checks.
Check this issue →SAFETYTread depth
For most UK cars and light vans, the legal minimum is 1.6mm across the central three-quarters of the tread and around the entire circumference. Check more than one point because wear can be uneven.
Check this issue →SAFETYTyre age and DOT/date code
Tyre age is one part of condition. The common four-digit manufacture code identifies production week and year, but tread depth alone does not prove that an older tyre is serviceable.
Check this issue →MAINTENANCETyre pressure
Use the vehicle manufacturer’s specified cold tyre pressures for the load being carried. Do not copy the maximum pressure printed on the tyre sidewall.
Check this issue →PROBLEMSUneven tyre wear
Uneven wear is a symptom, not a diagnosis. Pressure, wheel alignment, wheel balance, suspension condition and driving/use patterns can all contribute.
Check this issue →PROBLEMSWheel alignment and balancing
Alignment sets wheel geometry; balancing corrects rotating mass. They solve different problems and should not be sold as interchangeable fixes.
Check this issue →SAFETYWhen to replace a tyre
Replace a tyre when it is legally worn, structurally damaged, unsuitable for the vehicle, or a competent inspection identifies a condition that makes continued use unsafe. There is no single mileage number that applies to every tyre.
Check this issue →RIGHT NEXT STEP
TyreDeck should not sell you a tyre when the real problem may be elsewhere.
Worn or damaged tyre
Understand the condition, then compare replacement options only if replacement is actually needed.
Compare tyres →Uneven wear or vibration
Investigate alignment, balancing, wheels or suspension before sacrificing another tyre.
