The approved and most common GCC-spec tyre size for the Mazda 6 2.5 in the UAE is 225/45R19 on 19-inch alloy wheels. You'll find this size on majority of new and used models here, especially the higher trims. The 2.0L variant is less common, but when available, it often uses 225/55R17. The key difference is ride comfort versus looks: the 17-inch tyres with taller 55 sidewall absorb Dubai's road imperfections better, while the low-profile 19-inch tyres give a sportier look but can feel harsher on rough patches and are more prone to sidewall damage from potholes or kerbs.
For your reference, here is a comparison based on common UAE market observations and fitment:
| Specification | 225/45R19 (Common GCC-spec) | 225/55R17 (Base spec alternative) |
|---|
| Primary Use | Standard on higher trims (e.g., GT) | Found on base or older models |
| Ride Comfort | Firmer, more road feedback | Softer, more compliant |
| Cost per Tyre (AED) | ~600 - 900 (Premium brands) | ~450 - 700 (Premium brands) |
| UAE Suitability | Excellent for highway stability | Better for uneven city roads |
- Fuel economy impact: Expect a negligible difference, around 0.2-0.4 km/l less with the heavier 19-inch setup due to increased rolling resistance, based on mixed driving on Sheikh Zayed Road.
- Tyre pressure: Always follow the sticker on the driver's door B-pillar, not the tyre sidewall. For the 19-inch, RTA Dubai generally recommends around 33 PSI for normal load, which is critical in our summer heat to prevent overheating.
- Annual cost consideration: A set of four premium 19-inch tyres (e.g., Bridgestone or Michelin) can cost AED 3,200+, lasting roughly 40,000-50,000 km with proper rotation. The 17-inch set is about 25% cheaper to replace. MOI UAE's annual vehicle inspection will fail your car for tyres with less than 1.6mm tread depth or any sidewall damage.
