According to the official GSO standard and the tire safety guidelines of the RTA Dubai, the "88H" marking on a tire means that it has a load index of 88 (which corresponds to a maximum load capacity of 560 kg per tire) and a speed rating of H (certified for a maximum speed of 210 km/h). This rating is crucial for safety and vehicle performance under the specific conditions of the UAE, where highway speeds on the Sheikh Zayed Road or the Dubai-Abu Dhabi highway can be high and summer temperatures routinely exceed 40°C.
For a typical GCC-spec family SUV like the Hyundai Tucson or Kia Sportage, a 88H-rated tire is a common factory fitment. Here is a comparison of what these ratings mean for your vehicle:
| Rating | Maximum Load per Tire | Maximum Certified Speed |
|---|
| 88 | 560 kg | - |
| H | - | 210 km/h |
- Load Capacity (88): A load index of 88 means each tire can safely carry 560 kg. For a vehicle with four tires, this gives a theoretical maximum vehicle load of approximately 2,240 kg. This must encompass the curb weight of the car, all passengers, luggage, and any modifications. Exceeding this, especially during long trips with a full family load, can lead to overheating and premature tire wear or failure, a key point emphasized in MOI UAE's road safety campaigns.
- Speed Rating (H): The 'H' rating confirms the tire is engineered to dissipate heat and maintain integrity at sustained speeds up to 210 km/h. It's important to note that this rating applies to tires that are properly inflated, in good condition, and not overloaded. A tire's actual safe speed capability decreases with age, wear, and under-inflation. For sustained high-speed driving common on UAE highways, using a tire with a speed rating at or above the vehicle's top capability is a critical safety measure. The price difference between an H-rated and a higher V-rated tire for the same size can range from 50 to 150 AED per tire, impacting the total cost of ownership (TCO) when replacing a full set.
