The five-year rule: how a tyre with full tread still fails inspection
Every tyre carries a DOT code moulded into the sidewall, and the last four digits are the part that matters here: two digits for the production week, two for the year. 3523 means week 35 of 2023. UAE practice, built on the Gulf standard for tyres, treats five years from that production date as the end of a tyre's legal life on the road, regardless of how much tread is left. The logic is chemical rather than mechanical: rubber compounds oxidise and harden with age, and the process runs far faster in a climate where asphalt surface temperatures pass 70 degrees in summer. An aged tyre can look showroom-fresh and still delaminate at highway speed.
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.
