FAQ


Types of Tyres


When should I put winter tyres on? 

Winter tyres are best bought and fitted before the colder months and bad weather conditions such as sleet, ice and snow set in. Should you live in a rural area that experiences difficult and prolonged weather conditions, winter tyres can prove to be an excellent year-round tyre.


Are all-season tyres worth it? 

If you’re running your car in a climate that doesn’t experience extreme weather conditions, all-season tyres can be a worthwhile purchase. 

In less severe and unpredictable climates such as the UK’s, all-season tyres can save expenses and the effort of changing winter tyres and summer tyres. They also offer a better winter performance than both summer tyres in cold conditions and winter tyres in summer. 


Are run-flat tyres worth it? 

If you’re after a little extra peace of mind, run-flat tyres are certainly a good investment. They allow you to continue driving on a punctured tyre at a speed of 50mph for a maximum distance of 50 miles, allowing you to safely reach a service station rather than changing the wheel at the side of the motorway or waiting on breakdown recovery. 


What tyre is best for my car? 

Which tyre best suits your car depends on both your needs and the car model. Here at Green Flag, we offer a selection of tyres ranging from budget options to premium brands, so research your car model, tyre size and discover the right option for you. 


Tyre maintenance 



What is the correct tyre pressure? 

The correct tyre pressure will depend on the weight that your car is carrying. You’ll be able to find information on tyre pressure in your vehicle handbook, as well as the inside of the driver’s side door and the car’s petrol cap. You can read more on this in our guide to understanding tyre pressure[2]


How do I check tyre pressure? 

Check your vehicle handbook for information on tyre pressure; to check tyre pressure, unscrew the dust cap from the tyre valve and securely attach a tyre pressure gauge. Press down onto the gauge firmly, the tyre pressure reading will then appear on the gauge. 


How can I check my tyre size?

Tyre size can be found on the sidewall of the tyre itself where you will also find a serial number. 


EU tyre labelling



Fuel efficient tyres

Fuel efficient tyres are labelled with an image of a petrol pump and tyre, fuel efficiency is usually included to the left of this label and gives an indication as to how much energy is lost when the tyre is in motion. Known as rolling resistance, the lower the resistance the lower your fuel consumption and CO2 emissions. 


Wet performance tyres

Wet performance tyres are labelled with the image of a tyre and a rain cloud, on the right of this label you will find information on how well the tyre grips while on wet roads. 


Low noise pollution tyres

The tyre’s noise levels are shown in decibels at the bottom of the tyre performance label. One black wave symbol indicates the best noise level, while three indicates a poorer performing tyre.
