Insurance and liability: the fine print that turns on your tyres
UAE motor insurance policies require the vehicle to be roadworthy, and tyres are the component insurers examine first after a serious single-vehicle accident. A claim following a highway blowout can be reduced or rejected if the tyres are found to have been beyond the five-year age limit, worn below the legal tread depth, or visibly damaged before the incident. The surveyor's report will record DOT dates as a matter of routine. In other words, running old tyres does not just risk the AED 500 fine; it can put the entire value of an accident claim in question, along with liability for damage to others.
Modification is the second trap. Changing wheel and tyre sizes away from the manufacturer's approved fitments, fitting different sizes front to rear where the maker does not specify it, or deleting run-flats on a car designed around them are all changes an insurer can treat as undeclared modifications. None of this means you can never change anything; it means changes should stay within the approved fitment list in your handbook, and anything beyond it should be declared to the insurer in writing before renewal rather than discovered by a surveyor afterwards.
