Everything You Need to Know about Tyres (2024)

Correct tyre pressure is fundamental for optimum tyre performance. Every aspect of driving will be affected by under or over-inflation, so it’s important for you to know exactly what your tyre pressure should be and to check your tyre pressure regularly.

The recommended pressure for your tyres can be found in your vehicle handbook, or alternatively, it should be visible on the inside of the driver side door.

Driving with the correct tyre pressure will ensure optimised handling and traction in all weather conditions. Correct tyre pressure also has a positive impact on braking distances and fuel efficiency.

What’s more, an incorrectly inflated tyre will also wear down your tyre treads faster, meaning you’ll need to replace your tyres sooner.

For more information on tyre pressures read our guide on what your tyre pressure should be.

You can check tyre tread by using a tread depth gauge - relatively inexpensive and can comfortably fit inside your glove compartment.

You can also check for Tread Wear Indicators on your tyre, usually marked up alongside the letters TWI on your tyre’s sidewall. If these indicators are smooth with the tread, you should replace your tyres immediately. Lastly, you can use the 20p test, which couldn’t be simpler. Watch the video a guide to do so.

Tyre tread is vitally important for grip, traction and resistance to aquaplaning. In the UK, the legal limit of tyre tread is 1.6mm, but it’s important to check tyres regularly and keep them well maintained.

If you notice uneven wear when checking your tyre tread, this might be a sign of incorrect tyre pressure or a wheel alignment issue.

There’s a few more specific details to look out for – read our guide on checking tyre treads for a complete overview. There are also checks and maintenance you can carry out prior to your MOT test to ensure your tyres pass the UK MOT test.

Your tyres will last longer the better you look after them. Taking good care of your tyres will extend their lifespan and by maintaining them well, they’ll perform well until the day you need to replace them.

1. Full size matching spare: a tyre that is exactly the same as those currently on your vehicle,

2. Full size non-matching spare: a full size tyre that differs from those currently on your vehicle,

3. Full size temporary spare: this is a lightweight tyre designed to get you to a dealer or garage to replace the flat tyre,

4. Folding temporary spare: an inflatable or collapsible spare tyre designed to get you to a dealer or garage to replace the flat tyre,

5. Compact temporary spare: A smaller, lighter tyre engineered to allow the driver to continue their journey to a garage for repair or replacement.

As Jon Benson from Tyre Reviews explains in this video, summer tyres are designed to be excellent in the dry and wet when the weather is warm, but as soon as the temperature drops below 7°c, so will the performance.

Winter tyres contain a higher proportion of rubber, making them softer with a higher rate of elasticity. This increases the level of grip the tyre is able to offer in temperatures below 7°c. Winter tyres also have a different tread pattern containing sipes to give you the best possible performance on snow and ice. The softer and more elastic rubber on winter tyres degrades quickly in the warmer weather of summer as they are designed to be a winter weather specialist.

If you live somewhere that gets especially cold in winter with a lot of snow and ice, then choosing summer and winter tyres may be your best option. This will give you optimal performance in the warmer months, but as the temperature drops, you’ll have the best tyres for those wintry conditions.

An all season tyre blends the best of both the summer and winter tyre into one package, meaning you can run it all year round. This tyre is best if you live somewhere in the country that doesn’t get especially cold or see so much snow and ice. You will still get good performance in the summer and when the temperature drops, the tyre has the elasticity in the rubber to provide good winter performance too.

If you have an SUV or 4x4 vehicle, then you’ll also need to choose a tyre that’s appropriate for that vehicle.

An SUV tyre such as the Asymmetric 3 SUV takes the features of a car tyre and builds on it for an SUV specific application. This allows for the higher weight and higher loads of an SUV vehicle to be put to the ground safely, while retaining good levels of comfort, safety and excellent grip for handling and breaking.

If you spend a lot of your time off road, then a 4x4 tyre such as the Goodyear Wrangler DuraTracis ideal. The tyre is designed for 80% off road use and 20% on road use. Features include reinforced sidewalls and an aggressive tread pattern, which give you excellent grip off road without risk of puncture.

If you are looking for a 4x4 tyre with more on road performance, the Goodyear Wrangler All-Terrain Adventurebridges the gap between the SUV tyre and the off road 4x4 specialist tyre. The tyre is designed for 50% off road and 50% on road, so you can still use it off road regularly, but it’s got nicer road balance than the DuraTrac tyre.

Original Equipment (OE) tyres are tyres specifically designed by tyre manufacturers alongside car manufacturers for a specific vehicle, to ensure that the individual vehicle’s performance can be maximised.

This usually takes place in the early development cycle of a new vehicle and takes into consideration various aspects of tyre performance, such as handling, braking, traction, tread wear, noise and vibration. Development cycles can take 2-3 years, including lab and bench tests as well as several prototype tyres over hundreds of thousands of real world miles.

When it comes to replacing your tyres, it’s always a good idea to check what the OE tyres are for your vehicle. OE tyres will have their own specific mark fitment, such as a star marking for BMW, MO for Mercedesand AO for Audi.

Take a look at our OE tyres for all car manufacturers here.

The EU tyre label provides important safety and environmental information about each tyre. It helps you compare tyres for wet grip, fuel efficiency and noise.

Fuel efficiencyis rated from A to G on a colour-coded scale.A (green)= highest fuel efficiency rating.G (red)= lowest fuel efficiency rating.

Wet grip is the tyre’s ability to stick to the road in wet conditions. The EU rating focuses only on one aspect of wet grip – the wet braking performance of the tyre. Wet grip is rated from A to F: A = highest rating and F = lowest rating.

Noise Rating measures the pass-by noise a car makes that comes from the tyres. It is measured on a scale of decibels, depicted as waves. 1 black wave = quiet, 2 black waves = moderate and 3 black waves: noisy.

See our guide to the EU Tyre Labelfor exact details.

At Goodyear, we’re continually developing new technology and looking for innovative ways to improve our tyres. Our quality control engineers are also always on hand to test tyres when they’re made to make sure they’re up to scratch.

The manufacturing process typically follows five key steps:

1.Blend:up to 30 different kinds of rubber, fillers and other ingredients are mixed in giant blenders to create a black, gummy compound that will be sent on for milling.

2.Mill: the cooled rubber is cut into strips that will form the basic structure of the tyre itself. At this stage, some of the tyre parts prepared are then coated in another type of rubber.

3.Build: the tyre is built from the inside out using a tyre-building machine. The result is a ‘green tyre’ – a tyre that is beginning to look finished.

4. Cure:the green tyre is then vulcanised with hot moulds in a curing machine, compressing all of the parts of the tyre together and giving the tyre its final shape, including its tread pattern and manufacturer’s sidewall markings.

5.Inspect:trained inspectors using special machinery will now carefully check each tyre for the slightest blemish or imperfection before it can be shipped for sale.
