The marking "88H" molded on the tire sidewall indicates a load capacity of 560 kg and a maximum certified speed of 210 km/h. This is crucial in the UAE, not just for safety but also to pass the mandatory RTA annual vehicle test, as using non-compliant tires can lead to a failed inspection. For popular GCC-spec vehicles accustomed to local conditions, here's a typical match:
| Vehicle Model (GCC Spec) | Typical Tire Size | Common Load/Speed Rating | Suitability for 88H |
|---|
| Toyota Corolla / Nissan Sunny | 195/65R15 | 91V, 88H | Acceptable (check owner's manual) |
| Hyundai Tucson / Kia Sportage | 225/60R17 | 99H, 100V | Insufficient load rating |
| Toyota Land Cruiser (full load) | 285/60R18 | 114V, 120Q | Dangerously insufficient |
- Load Index (88): This is the most critical number. 88 corresponds to 560 kg per tire. MOI UAE traffic regulations emphasize vehicle load limits, and exceeding the tire's capacity is a primary cause of blowouts on high-speed highways like the Dubai-Abu Dhabi road, especially in summer heat. For a sedan, the total of four tires (4 x 560 kg = 2,240 kg) must exceed the vehicle's Gross Vehicle Weight Rating (GVWR), which includes passengers, luggage, and fuel.
- Speed Rating (H): The 'H' rating certifies the tire for sustained speeds up to 210 km/h. While the legal limit is lower, this rating ensures structural integrity under the routine high-speed, high-temperature driving on UAE highways. The RTA Dubai's vehicle inspection manual references these speed ratings as a key safety parameter. The cost implication is direct: a set of H-rated tires for a common sedan can range from AED 800 to AED 1,500, while a higher V-rating (240 km/h) may add 15-20% to the cost, which is often unnecessary for daily commuting.
