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.

A last practical check is behavioural rather than bureaucratic. A competent fitter uses a torque wrench for final tightening rather than hammering the impact gun to maximum, resets or checks the TPMS after the job, sets pressures to the placard on your door jamb rather than a generic number, and tells you unprompted to re-check torque after the first 50 to 100 kilometres. Any one of those habits is a good sign; all four together mean you have found your regular, and same-vendor rebooking exists for exactly that moment.

A large share of German premium cars in the UAE arrive on run-flat tyres and carry no spare wheel, no jack, and sometimes no space where a spare would go. Run-flats have reinforced sidewalls that support the car for a limited distance at reduced speed after a full pressure loss, which is why the maker felt safe deleting the spare. Replacing them with conventional tyres purely to save money changes the safety design of the car: a puncture that was a controlled drive to a workshop becomes a roadside stop on a hard shoulder with no spare. If you make that change, do it knowingly, carry a quality repair kit or arrange roadside cover, and tell your insurer.

Run-flats also have stricter repair rules. Most manufacturers advise against repairing a run-flat that has been driven flat at all, because the reinforced sidewall can be damaged internally in ways no visual inspection catches. A fitter who cheerfully plugs a run-flat that limped twenty kilometres home is cutting a corner you will not see until it matters. Expect the honest answer to be replacement more often than repair, and expect run-flat sets to price at the top of the market range.

Nitrogen inflation has real but small advantages. Nitrogen molecules permeate rubber more slowly than oxygen, so a nitrogen-filled tyre loses pressure somewhat more slowly over the weeks, and the dry gas carries no water vapour, which means slightly more stable pressures as temperatures swing and less internal corrosion of steel belts and TPMS valve hardware. In a country where the gap between a January dawn and an August afternoon can be 35 degrees, more stable pressure is a genuine, if modest, benefit. Airlines and racing teams use nitrogen for these reasons at extremes far beyond road driving.

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.
