How to verify a fitter is legitimate: licences, premises and paper trail
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.
