لماذا تسخن عجلات سيارتي؟ الأسباب الشائعة في سيارات الإمارات

In the UAE's conditions, hot wheels are most commonly caused by stuck brake calipers or failing wheel bearings, exacerbated by high ambient temperatures and dusty roads. Data from workshops in Dubai and Abu Dhabi shows that on popular GCC-spec SUVs like the Toyota Land Cruiser and Nissan Patrol, which are heavy and frequently used in stop-and-go traffic, the front brake calipers are a primary culprit. For instance, a 2021 Patrol with 80,000 km driven mainly on Sheikh Zayed Road may show caliper seizure due to dust ingress, leading to constant pad-drag and overheating the entire wheel assembly. The RTA Dubai's vehicle inspection statistics highlight brake system defects as a leading cause of roadworthiness failures, especially after the summer months. A complete front brake caliper repair for a common sedan like the Toyota Camry can cost between AED 1,200 to AED 1,800 at independent garages, influencing the total cost of ownership. -Brake caliper issues are a frequent cause of hot wheels in UAE traffic. -RTA Dubai inspection data often flags brake system problems post-summer. -Wheel bearing failure risk increases with high mileage and off-road use.

I drive a 2018 Toyota Prado for my daily commute from Sharjah to Dubai. Last summer, I noticed the front right wheel was extremely hot to the touch after getting stuck in Dubai-Sharjah rush-hour traffic for over an hour. My mechanic in Al Quoz found the brake caliper piston was stuck, probably from all the dust and heat. He cleaned and lubricated the sliders, and the problem hasn't come back since. It's a common issue here if you don't service your brakes regularly.

As a mechanic in Abu Dhabi, I see this weekly. The combination of 45°C summer heat, constant A/C use adding engine load, and fine sand on the roads is brutal on brakes and bearings. For the Toyota Hilux and Ford Territory models popular with delivery fleets, we often find the wheel bearings have lost their grease due to cracked seals from the heat. The tell-tale sign is a humming noise that gets louder with speed on the Dubai-Abu Dhabi highway. Don't ignore it; a seized bearing can lock the wheel.

In the used car showroom, when we get a trade-in with high mileage, hot wheels are a red flag. It often points to deferred maintenance. For a sedan like a Nissan Sunny or Kia Cerato that's done 150,000 km mostly in city driving, the brakes have likely been worked hard. We check for uneven pad wear and hub temperature after a test drive. A hot hub usually means the bearing needs replacement before we can resell the car.

After a day of desert driving in the Liwa dunes, feeling the wheels on my Mitsubishi Pajero is normal—the brakes work hard on descents. But if one wheel is significantly hotter than the others when driving on normal roads, it's not normal. For us off-road enthusiasts, it's often a slightly bent brake rotor or a caliper that got packed with sand during the dune bashing. A good post-desert wash including a careful brake clean is essential to prevent this.
