When to Replace Your Tyres in the UAE: 7 Signs to Check

1. Tread at the wear bars

The legal minimum tread depth commonly cited in the UAE is 1.6 mm, the same figure Michelin gives as the legal limit. Every tyre has small raised bars moulded into the bottom of the main grooves, called tread wear indicators. When the tread surface is level with these bars, the tyre has reached 1.6 mm and must be replaced.

To find the bars, look for a small triangle, logo or the letters TWI on the shoulder of the tyre; the bar is in the groove in line with that mark. A tread depth gauge gives an exact reading and costs very little. Check across the width of the tyre, because the inner edge can wear faster than the part you can see.

Remember that 1.6 mm is a legal minimum, not a recommendation to wait. Michelin explains that tread depth helps drain water from under the tyre, so grip on wet roads falls as the tread wears. If your tyres are close to the bars before summer or a long trip, it is sensible to plan the replacement rather than wait for the limit.

2. Age, even with good tread

Rubber ages over time, and UAE heat and sun speed this up. Read the last four digits of the DOT code on the sidewall to find the production week and year. Michelin recommends a professional check at least once a year after five years of use and replacement ten years after manufacture, including the spare.

Low-mileage cars are the ones most often caught out, because the tread looks fine while the rubber has hardened. See our guide to tyre expiry and the DOT code for more detail.

3. Bulges, cuts and cracks

A bulge or blister on the sidewall means the internal cords are damaged, usually from hitting a kerb or pothole. The tyre can fail without warning and must be replaced, not repaired. Michelin's advice on sidewall damage is to have the tyre checked by a professional straight away.

Fine surface cracks in the sidewall or between tread blocks are a sign of ageing. Deep cracks, cuts that show cords, or damage near the bead (where the tyre meets the rim) also mean replacement.

4. Punctures that cannot be repaired

Many tread punctures can be repaired properly from inside the tyre. Punctures in the sidewall or shoulder, large holes, tyres that have been driven flat, and tyres with several previous repairs close together are usually not repairable. A tyre that keeps losing air after a repair also needs a closer look.

Our article on whether to repair or replace a punctured tyre explains the limits, and the puncture repair service will tell you which applies to your tyre.

5. Uneven wear

Wear on one edge, in the centre only, on both shoulders, or in patches tells you something is wrong. Inner or outer edge wear often points to alignment. Centre wear suggests over-inflation; shoulder wear suggests under-inflation. Patchy, cupped wear can come from worn suspension or imbalance.

A badly worn edge can reach the wear limit long before the rest of the tread, so measure the worst point. Replace the tyre if needed, then fix the cause with a wheel alignment or suspension check so the new tyres do not wear the same way.

6. Vibration, noise or pulling

A new vibration through the steering wheel or seat, a rhythmic noise that changes with speed, or the car pulling to one side can come from a damaged tyre, a separated belt, a bent rim or a lost balance weight. Do not drive long distances until it has been checked.

If the tyres are sound, wheel balancing often cures vibration. If a tyre has an internal separation, it will need replacing.

A five-minute monthly check

Most of the signs above are easy to spot if you look regularly. Once a month, and before any long drive, park on level ground in the shade and go round the car with a torch and a gauge. Turning the steering wheel to full lock lets you see more of the front tyres' tread and inner shoulders.

Doing this regularly also gives you a baseline. You will notice when one tyre starts wearing faster than the others or needs air more often, which is usually the first sign of an alignment problem, a slow puncture or a leaking valve. Catching it early can save the tyre.

1. Measure tread depth at the inner, centre and outer grooves of each tyre.
2. Check the DOT date on any tyre you have not recorded.
3. Look along both sidewalls for bulges, cuts and cracks.
4. Look for nails, screws or stones in the tread.
5. Check and set cold pressures, including the spare.

7. The law and how to replace

Khaleej Times reports that driving with worn-out or unfit tyres carries a Dh500 fine and four black points, with the vehicle liable to be impounded for a week. Police campaigns, especially in summer, also remind drivers to check tyre pressure and the manufacturing date. A tyre at or below the wear bars is a safety risk as well as a legal one.

When you replace, match the size, load index and speed symbol, and fit the same tyre on each axle. 800 Motor provides tyre replacement at your home, office or a partner centre across Dubai, Sharjah, Abu Dhabi and Ajman, with the tyre model, production date and fitted price confirmed in the quote. Mid-range options such as Dunlop cover many common sizes.
