The five-year rule: how a tyre with full tread still fails inspection
This is not a theoretical guideline. Vehicle testing centres check DOT dates during the annual registration inspection, and a tyre past the five-year mark is a straightforward fail. Drivers routinely discover this the expensive way: they arrive for renewal with tyres they bought only three years ago, and fail anyway, because the tyres had already sat in a warehouse for two years before fitting. That is why the date check belongs at the point of purchase, not the inspection lane. A reputable fitter will show you the DOT stamp on each tyre before it goes on the rim; if the stock being offered as new is already a year or more old, ask for fresher production or walk away.
There is also a traffic-law layer on top of the registration layer. Driving on worn or deteriorated tyres carries a fine of AED 500 and four black points under the federal traffic rules, and police can impound the vehicle. Tread depth below 1.6 millimetres, visible cords, sidewall cracking or bulges all qualify. In practice, summer blowout campaigns run by police in several emirates make this one of the more actively enforced vehicle-condition offences on UAE roads.
