How to Check Tyre Tread Depth and Legal Limits in UAE

Tread depth is one of those things drivers rarely check until a tyre shop points it out — but it directly affects how well your car grips the road, especially during the UAE’s sudden summer downpours. Knowing what is the minimum tread depth required for car tyres, and how to check it yourself, takes two minutes and could save you a fine or worse.

The legal minimum in the UAE

UAE traffic regulations require a minimum tread depth of 1.6mm across the tyre. This is a legal minimum, not a safety target — vehicle inspection centres and traffic police can flag or fine vehicles with tyres worn below this level, and it’s genuinely unsafe to drive on tread that thin, particularly in wet conditions.

The coin test

You don’t need special tools to get a rough read on tread depth. Take a coin — a AED 1 coin works well — and insert it into the main tread grooves at several points around the tyre, not just one spot.

• If the tread covers a significant portion of the coin’s edge, you likely still have healthy depth.
• If the coin’s rim is nearly exposed or fully visible, your tyres are approaching or below the legal limit and need replacing.

Using a tread depth gauge

For an exact reading, a simple tread depth gauge (widely available and inexpensive) gives you a precise millimetre measurement. Insert the pin into the groove, press the shoulder flat against the tyre, and read the depth directly. Check at least three points across the width of the tyre and in a few places around its circumference, since wear isn’t always even.

Built-in tread wear indicators

Most modern tyres have small raised bars moulded into the base of the tread grooves. When the surrounding tread wears down to the same level as these bars, the tyre has reached its legal minimum. They’re an easy visual check without needing any tools at all.

Why uneven wear matters too

If one area of the tyre is significantly more worn than the rest, tread depth alone won’t tell the full story. Uneven wear usually points to alignment or suspension issues that are worth having checked, since they’ll wear out your next set of tyres just as unevenly.

What to do if you’re close to the limit

Don’t wait until you’re exactly at 1.6mm. Reduced tread depth affects braking distance and wet-weather grip well before it becomes illegal, so it’s worth replacing tyres a little ahead of the legal minimum.
