Tyre fitting is licensed trade activity in every emirate. A fixed workshop holds a trade licence from the local economic department covering tyre repair and sales, plus civil-defence compliance for the premises, since a building full of stacked rubber is a serious fire load. A mobile fitting operation is typically the outreach arm of a licensed workshop, running vans under the same commercial licence. The verification questions are short: what is the licence name and number, which emirate issued it, and does the invoice you receive carry that trading name with a TRN for VAT. A provider who cannot produce an invoice with a tax registration number is operating informally, and you have no recourse when something goes wrong.

Documentation matters most in the failure case. If a wheel comes loose because lug nuts were not torqued, or a fresh tyre fails and causes damage, your route to compensation runs through the provider's commercial identity and their liability insurance. Licensed garages carry insurance precisely because wheel and tyre work is safety-critical; an unlicensed operator with a borrowed compressor carries nothing. This is one of the quiet advantages of booking through a platform that vets its vendors: tamam lists verified providers with transparent AED price ranges, and the booking, payment and job record all live in the app, which means there is always a documented trail of who did what to your car and when.

Modification is the second trap. Changing wheel and tyre sizes away from the manufacturer's approved fitments, fitting different sizes front to rear where the maker does not specify it, or deleting run-flats on a car designed around them are all changes an insurer can treat as undeclared modifications. None of this means you can never change anything; it means changes should stay within the approved fitment list in your handbook, and anything beyond it should be declared to the insurer in writing before renewal rather than discovered by a surveyor afterwards.

Liability also runs the other direction, toward the fitter. If a wheel detaches or a repaired tyre fails and the cause is workmanship, the workshop's insurance responds, but only if you can prove who did the work. Keep the invoice, keep the booking record, and photograph the DOT dates of newly fitted tyres. It takes ninety seconds and it converts a hopeless argument into a documented claim. The same records help in the ordinary case too: manufacturer warranties on tyres cover defects, not damage, and the distinction is argued with paperwork, so a dated invoice showing where and when the tyre was fitted is the difference between a goodwill replacement and a shrug.

What nitrogen is not is a substitute for checking pressures. Underinflation remains the single biggest cause of highway blowouts in the Gulf: a soft tyre flexes more, flexing generates heat, and heat is what kills tyres here. That mechanism operates identically whatever gas is inside. The compliance-minded routine is a monthly pressure check against the door-jamb placard, done cold, plus a visual walk-around for bulges and embedded objects before any long highway run. If a vendor offers nitrogen as an inexpensive add-on at fitting time, it is reasonable value; if it is being sold as a safety system that replaces maintenance, it is being oversold.

One caution: mixed fills are harmless but pointless. Topping up a nitrogen fill with ordinary air at a petrol station does no damage whatsoever, and the widespread belief that it does keeps drivers running underinflated while they hunt for a nitrogen point. Correct pressure with plain air always beats low pressure while waiting for the right gas.
