The primary causes of unusual rear tyre wear on cars in the UAE are incorrect wheel alignment, improper inflation, and suspension wear, accelerated by local driving conditions. GCC-spec vehicles, like the popular Toyota Land Cruiser or Nissan Sunny, are calibrated for high heat but can suffer quickly from misalignment. A key factor is frequent driving on desert roads or over unpaved ground, often combined with carrying heavy loads, throwing the suspension geometry off. RTA Dubai's vehicle inspection data highlights wheel misalignment as a leading cause of tyre failure during annual registration renewal. Furthermore, UAE Ministry of Energy and Infrastructure guidelines emphasize that over-inflated tyres, often used to attempt fuel savings on highways like Dubai-Abu Dhabi highway, wear the centre tread faster, while under-inflation from neglecting monthly checks wears the shoulders, especially under high summer temperatures. For a typical family SUV like a Hyundai Tucson, a single front wheel alignment being just a few degrees out can cause rapid, uneven rear tyre wear within 10,000 km. The total cost is significant: a set for a Toyota Camry can cost 1,200-1,800 AED, and uneven wear may force replacement yearly instead of the typical 2-3 years, adding over 600 AED annually to your running costs. A timely 150-300 AED alignment check is a sound investment.
