The correct tyre pressure for your car or SUV in the UAE is primarily found on a sticker inside the driver's door frame (B-pillar) or in the fuel filler flap, and it's crucial to adjust these figures for local conditions. For a GCC-spec Toyota Land Cruiser, the manual might state 32 PSI, but running at 34-35 PSI (around 2.4 bar) is common practice here to account for high asphalt temperatures on roads like Sheikh Zayed Road, which can increase pressure by 4-5 PSI when hot. The RTA Dubai consistently highlights in its vehicle safety guides that incorrect tyre pressure is a leading factor in hot-weather tyre failures. For a typical family SUV like a Hyundai Tucson, the recommended cold pressure is often 33 PSI (2.3 bar) for normal loads. A key calculation many fleet managers use is cost per km: under-inflation by just 5 PSI can increase rolling resistance, reducing fuel economy by about 2-3%—for a car that averages 10 km/l, this means an extra cost of roughly 15-20 fils per km at current Special 95 fuel prices. The MOI UAE's annual traffic safety reports frequently cite tyre-related incidents, especially during summer months, reinforcing the need for monthly checks. The annual depreciation impact is also notable; uneven wear from chronic under-inflation can shorten tyre life by up to 25%, forcing a replacement cycle of 2-3 years instead of 3-4 years on UAE highways.
