In the UAE's climate, a set of high-quality summer or all-season tyres typically lasts 2 to 3 years, or approximately 40,000 to 60,000 km, for the average driver. This estimate is based on the extreme operating conditions here. The RTA Dubai's vehicle inspection guidelines emphasize tread depth as a critical safety factor, requiring a minimum of 1.6mm. However, for optimal wet-weather performance on rare rainy days, replacing tyres at 3mm is a common professional recommendation. The MOI UAE's traffic safety reports consistently cite tyre failure as a leading cause of highway accidents, particularly during summer months when asphalt temperatures can exceed 60°C. The total cost of ownership (TCO) for tyres here is significantly influenced by heat degradation rather than just tread wear. For a popular SUV like the Toyota Land Cruiser, a set of four tyres (e.g., 285/60 R18) can cost around AED 3,200. If they last 50,000 km, the cost per kilometre is about 6.4 fils. Annual depreciation of the tyre's rubber compound due to UV exposure and heat is a real, often overlooked, cost that shortens the lifespan well before the tread is fully worn, especially for vehicles parked outdoors in direct sun.
- Primary Lifespan Determinant: Heat and UV exposure, not just mileage.
- Safe Tread Depth: Replace at or before 3mm for safety.
- Key Cost Factor: Degradation often outpaces tread wear.
