ما هي السرعة والمسافة القصوى المسموح بهما لإطار الاحتياطي المؤقت (المختصر) في الإمارات؟

In the UAE, a space-saver spare tyre (temporary spare) should not be driven faster than 80 km/h and should be used for no more than 80 km before replacement. This is the standard recommendation from vehicle distributors for GCC-spec models, aligning with the safety guidelines issued by authorities like RTA Dubai and Abu Dhabi Mobility for emergency tyre use on local highways. For example, if you have a puncture on Sheikh Zayed Road in a Toyota Land Cruiser or Nissan Patrol, switching to the small spare lets you drive to the next safe exit or service center at a reduced speed, but it's not designed for the 120-140 km/h flow of the Dubai-Abu Dhabi highway. The key risks here are the tyre's different diameter—which can strain the differential on 4WD vehicles common here—and its reduced traction, which is a major concern during sudden lane changes in heavy Dubai-Sharjah traffic or on dusty roads. Based on common garage rates in Dubai and Sharjah, the total cost of driving on a spare longer than advised (risking differential damage) far outweighs the AED 150-300 cost of a tow to the nearest tyre shop. A proper tyre should be fitted immediately, and most reputable shops in areas like Al Quoz or Sharjah Industrial Area can complete this within a few hours.

As a mechanic in a Sharjah workshop, I see this weekly. People drive from Dubai to Sharjah on the spare at normal speed because they're late for work. The main issue isn't just the tyre; it's the heat. A small spare, especially on a heavy sedan like a Nissan Altima, overheats quickly in our summer. I had a customer last July whose spare tyre partially disintegrated on Emirates Road after only 60 km because he was doing 100 km/h with the AC on full blast. The rule is simple: 80 km/h max, go straight to the nearest tyre repair, don't use it for your daily commute.

Managing a used-car showroom in Dubai, we always check the spare tyre's condition and manufacturing date during the pre-purchase inspection. A used spare that's never been touched but is over 7-8 years old is a red flag—it's dry and cracked, practically useless. For buyers, I explain that if the car comes with a space-saver, their effective range after a puncture is only about 80 km at a very cautious speed, which might not even get you from Silicon Oasis to the Deira side if traffic is bad. It's a compromise for boot space. Many families looking at a Hyundai Tucson or Kia Sportage prefer to buy a full-size alloy wheel as a spare for longer trips to RAK or Fujairah, for peace of mind.

For off-road driving in the desert near Liwa or Sweihan, a space-saver spare is worse than having no spare at all. It's completely unsuitable for sand dunes, soft sand, or even the gravel tracks to fossil rock. Its small size and low profile will instantly get stuck. If you get a flat out there, you're better off waiting for recovery. Any serious off-roader with a Pajero or Patrol replaces the temporary spare with a proper, matching tyre and wheel before even thinking about a desert trip.

From an insurance perspective, if you're involved in an accident while knowingly exceeding the 80 km/h or 80 km limit stated in your vehicle's manual, the surveyor from the insurance company can note it as a contributory factor. This could potentially affect your claim, especially if the tyre failure contributed to the loss. The MOI UAE and insurance companies emphasize using the vehicle as per manufacturer specifications. It's a small risk that's not worth taking when a tow truck or emergency tyre mobile service is just a phone call away in most urban areas.
