When it comes to the attributes of a car tyre, there are a few areas, which are essential in UK law, principally the tramp depth, speed, and load indexes, as well as the quality or durability of the tyre. Here, we will break down the various UK tyre laws and legal requirements that you, as the driver, need to be informed.
There should be no points where the tread depth goes below 1.6 mm as it is the least depth which is required. Because of this importance – and the fact that 1.6 mm is a legal requirement in many countries – tyre manufacturer’s often consolidate features to indicate the level of wear and tear on your tyre.
The law requires car tyres to have a minimum tread depth of 1.6mm in a continuous band around the central three-quarters of the tyre. To help you judge how much tread you have on your car tyres, manufacturers often mold tread bars at roughly 1.6mm. Many manufacturers now include a Tread Wear Indicator (TWI) within the grooves of the tyre tread which become more visible as the tyre wears down.
The tyre valve is often the most neglected and overlooked component within the wheel and tyre an efficient valve is important for the safe operation of the tyre. Wear on the valve seal, damaged screw threads, dirt and grit in the valve itself can lead to failure of the tyre at speed.
Inspect all tyres, including the spare, for signs of damage. Ensure all tyres are correctly inflated for the load you will be carrying and check your pressure settings regularly throughout extended trips. Check your tread depth against the legal requirements for all countries and allow extra if you plan on covering lots of miles. Check the age of your tyres: If they are five years old get, then changed before your journey and avoid sidewall impact wherever possible. If you do knock the sidewall, always check every tyre for signs of damage.
Ensure your vehicle is equipped with all emergency equipment the country requires you to carry by law, e.g. warning triangles and high-visibility jackets. Make sure your insurance is valid: check with your insurer if you are not certain. Car, Van and Leisure Batteries.

There are several simple steps you can take to get the maximum life and value out of your car battery. Make sure your cell voltage is checked when you have your car serviced. A fully charged battery will have a charge of 12.5 to 12.6 volts. When the engine is running this should rise to 13.7 to 14.7 volts.
Inspect your battery every few months to make sure it is clean and secure. A dirty battery connection will weaken the charge, so remove the connectors from the terminal to clean away grease, dirt and dried acid build-up. You could even apply a layer of multi-purpose grease to protect the battery from rust and corrosion.
As temperatures drop more power is needed to start the engine. To give your battery a helping hand, ensure all accessories are unplugged and switch off anything else that drains its power. Get into the habit of turning everything off before you leave your car.
Not driving your vehicle enough can lead to battery problems. Batteries will refuse to work when vehicles have been left standing idle. Equally, if your car is only used for short trips, the battery will not have enough time to recharge, which will ultimately leave it flat.
So you’ve had a flat tyre, what now? The most immediate need when you have a flat tyre is to get back on the road. You will usually have to address this by removing the punctured tyre and fitting your spare, safely out of the way of any traffic. Instructions on how to remove the punctured tyre and fitting the spare can be found in your vehicle’s owner’s manual. However, it is critically important to organise for the punctured tyre to be repaired as soon as possible. This is especially the case if your vehicle’s spare tyre is a space saver or speed limited.
What causes a flat tyre? A flat tyre is generally caused by a puncture to a tubeless tyre’s casing, allowing air to escape and causing the tyre to deflate. Punctures are usually caused by sharp objects like small nails, screws, glass shards and other road debris. These objects tend to cause punctures less than 5mm in diameter. If they occur within the tread area of the tyre, a repair can usually be made to the tyre.
Can my tyre be repaired? The area of the tyre where the puncture occurs will determine if the tyre is repairable. Generally, tyres with punctures in the tread area are repairable. Areas within the central ¾ of a tyre (shown in blue), which have a tread depth of no less than 1.6mm are minor repair areas and can be patched.
Tyres suffering from a major puncture to the tread or on the tyre sidewall and shoulder will be deemed unrepairable. If this happens, a new tyre will be needed to replace the punctured one How do we repair a puncture? The function of a puncture repair is to seal the tyre’s casing to prevent moisture or contaminants from entering the tyre casing or structure.
The tyre must be removed from the rim to perform a correct puncture repair. This allows for a complete inspection of the damage and ensures the plug used to repair the puncture bonds properly with the tyre casing to make it airtight. The repair is made from the inside out.
A puncture repair usually takes around 30 minutes to complete. It involves deflating and removing the flat tyre from the rim, assessing and repairing the puncture before refitting it to the rim and balancing the tyre on the wheel. It is then fitted to your vehicle and your spare placed back into storage.
