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.
What to check
Mileage depends on vehicle, axle, tyre design, pressure, alignment, load, roads and driving style.
Damage and ageing can make replacement necessary even with substantial tread remaining.
Correct the cause of abnormal wear before sacrificing a new tyre to the same problem.
Replacement is condition-led
Legal wear, structural damage, unsuitable fitment or a professional finding of unsafe condition are clear reasons to replace. Mileage alone is not a reliable replacement interval because use, load, pressure, alignment and tyre design vary.
Fix the cause of abnormal wear
If a tyre has worn rapidly or unevenly, diagnose the vehicle before assuming the tyre alone was at fault. This protects the new tyre and can reveal a pressure, wheel, geometry or suspension problem.
TyreDeck can help you spot warning signs, but it cannot inspect the tyre internally, measure damage, verify pressure calibration or certify that a tyre is safe to drive on. If you are unsure, avoid unnecessary driving and arrange a competent physical inspection.
What to do next
If replacement is genuinely needed, compare like-for-like tyre specifications and distinguish delivered from fitted prices.
