We all know how annoying and inconvenient a punctured tyre can be, not to mention the impact this can have on your safety whilst driving.
That's why Crown Garage offer a puncture repair or tyre replacement service!
If you have a puncture, whether it's fast or slow, or you are in need of a new tyre, we have the tools to get you safely on the road again. We only deal with mid-range or branded tyres, to ensure maximum safety of your vehicles, and our puncture repair kits are built to last and withstand your every day driving needs, albeit short or long distance driving.

If you have a punctured tyre, pop in to Crown Garage for a repair!
We have a seating area where you can sit and wait, or alternatively, you can drop your car off and pick it up once the repair is all done.
A repair can only be safely completed if the damage meets strict limits regarding location, size, and the condition of the tyre.
The 3 Core Puncture Limits
- Location: The puncture must be within the central three-quarters (60-70% depending on the tyre width) of the tread, commonly referred to as the "minor repair area". Punctures, sidewalls, or edge shoulders are strictly off-limits for repair because these areas experience immense flex and stress.
- Hole Size: The diameter of the damaged area must be 6 mm or less. If the object that punctured the tyre (like a bolt or large piece of metal) leaves a hole bigger than this, the tyre must be replaced.
- Number of Repairs: If your vehicle uses tyres with a speed rating of V or higher, the tyre is eligible for only one puncture repair in its entire lifetime.
When a Tyre Cannot Be Repaired
Beyond the specific puncture criteria, a garage will refuse a repair and require a replacement if:
- Tread Depth is Too Low: The remaining tread is below the UK legal limit of 1.6 mm.
- Structural Damage: There are signs of "run-flat" damage, bulging, exposed cords, or severe cuts to the rubber.
- Previous Faulty Repairs: Any existing patches are overlapping the new puncture, or previous fixes were not completed properly.

You should change your tyres when the tread depth drops below the legal limit 1.6mm, when they show signs of cracking or damage, or if they reach 5–6 years of age. Tyres should always be replaced in pairs on the same axle to maintain safe handling and grip.
Key Warning Signs to Replace Tyres
- Tread Depth: The minimum legal limit in the UK is 1.6mm across the central three-quarters of the tyre. However, we recommend replacing your tyres once the tread reaches 3mm to prevent a dramatic drop in wet-weather braking and handling.
- Age: Even if the tread isn't worn, tyres degrade over time. Most we recommend replacing tyres when they are 5–6 years old, and any tyre over 10 years old should be removed from service entirely. You can find the manufacturing date (a 4-digit code) on the tyre's sidewall.
- Visible Damage: Inspect your tyres regularly for cracks, cuts, bulges, or embedded objects (like nails or glass). A bulge in the sidewall is an immediate puncture hazard and requires an urgent replacement.
- Uneven Wear: If you notice your tyres are wearing unevenly such as balding on the inner or outer edges, it indicates a wheel alignment or suspension issue. You should have the underlying mechanical fault fixed and the tyres replaced.
How to Check Your Tread Depth at Home
- The 20p Test: Insert a 20p coin into the main tread grooves of your tyre. If the outer band of the coin is visible, your tread is likely below 3mm and you should consider a replacement.
- Tread Wear Indicators: Look for the small raised rubber bars molded into the bottom of your tyre's grooves. If the tread surface has worn down to be level with these indicators, your tyre has hit the legal limit
