What makes a tyre legal here: GSO standards, MOIAT conformity and heat ratings
The practical shorthand on the sidewall is the UTQG temperature grade, printed as A, B or C. Grade A indicates the best resistance to heat build-up at sustained speed, and it is the sensible minimum for a car that regularly runs the E11 or E311 in August. Speed rating matters for the same reason: heat generation rises with speed, and UAE highways combine 120-plus km/h limits with the buffer many drivers use. Fitting a lower speed rating than the manufacturer specifies is a compliance problem twice over, once at inspection and once with your insurer.
Grey-market imports are the trap. Tyres brought in through informal channels can be genuine brands in non-GCC spec, or worse, production intended for cooler markets and dumped here at attractive prices. The paperwork test is simple: a legitimate seller can tell you the tyre is GCC-spec and show conformity documentation on request, and the price will sit inside the normal market band rather than dramatically under it. When comparing vendors on the tamam app, treat a quote far below every other verified vendor for the same size and brand as a flag to investigate, not a bargain to grab.
