  • What Is Speed Rating

  • Speed Rating is set out by a tyre manufacturer by testing the tyres speed. These test consists of running the tyre for 10 minutes at 6.2mph intervals, as they increase the speed the tyre engineer will find the tyres speed rating.

    You will find the tyres speed rating letter on the tyre sidewall. This is always located at the end of the tyre size information i.e “V”.

  • What Is Load Rating

  • The load rating on your tyre relates to how much weight each tyre can carry. It’s very important that you get this right when choosing your tyre.

    You can also check the load rating on your existing tyres, this is usually found after the diameter reading and before the speed rating on your tyres sidewall. 

    Check the load rating on your existing tyres - on the example below the load rating is 87 which means that each tyre can bear up 545kg in weight

    We’ve provided a handy guide to the load index and that actual weight in kg’s the tyre can take.



  • What is tyre performance labeling

  • Tyre Labels were introduced by the EU and are designed to make tyre comparison simple. There are three key measures for each and every tyre for sale throughout Europe; Fuel Efficiency, Performance in the wet (braking distances) and Road Noise. Once you know what to look for you will quickly understand what each label means.

    Tyre labelling is very easy to understand, they are colour and letter coded in a similar way to how we compare white goods such as fridges and freezers. Tyres are rated from A-G for each category, A being the best.

    We offer you a chance to filter for tyres that give you the best braking performance, the best fuel efficiency or the lowest road noise when you look through our range.

    Fuel Efficiency.

    EU Labelinhg - Fuel Efficiency

    Tyres that are rated “A” will give you a much more efficient drive than those rated “G”. It is a wise choice to choose a tyre that is more fuel efficient. It is not only a massive benefit to you, by saving you money and taking more time between trips to the pump, but it also has a more positive environmental effect than lower rated tyres.

    A car fitted with four A-rated tyres will save a massive 80 litres of fuel over the life of the tyres, which is the equivalent of over a whole tank of petrol saved and roughly £110 with today’s prices. Driving at 50mph, A-rated tyres will use around 7.5% less fuel than if your tyres were G-rated.

    Wet Performance.

    EU Tyre Labeling Wet Performance

    How your tyres perform on wet roads is extremely important. They are the only thing keeping you glued to the road, and with the risk of aquaplaning during very bad weather, choosing a tyre that has a higher wet performance rating than others could potentially be life-saving.

    Again, you can review how well a tyre has been classified with the A-G rating, with A-rated tyres having a much shorter stopping distance, and therefore being much safer, than G-rated tyres.

    If you have a car with four A-rated tyres, you will stop up to four car lengths shorter than G-rated tyres, which can prevent crashes and potentially save lives. At 50mph you will have a decreased stopping distance of up to 18m, which is up to 30% better than more poorly rated tyres.

    Road Noise.

    EU Tyre Labelling Road Noise

    This diagram is different to the A-G rated symbols of the fuel efficiency and wet grip. Tyres are rated on a scale of three noise waves, as well as a decibel level of what the maximum noise level recorded for that tyre is. In the future, regulations will be put in place to set a maximum road noise level from tyres.

    If a tyre has three black waves then it is one of the noisier tyres. It means that the level of noise that it emits is actually greater than what the future regulation will be, but it is still legal by today’s standards.

    Two waves mean that a tyre performs at an average level and the noise emitted is equal to, or three decibels lower than, the future regulations.

    A single wave indicates a very low noise from the tyre. You will get a minimum of three decibels lower than the future noise limit - and even lower in some cases. Three decibels might not sound like a lot of difference, but you will certainly realise the change when you start driving.

    Don’t forget, the noise that you hear inside the car isn’t always relative to the noise being emitted by your tyres on the outside.

  • Is It Ok To Fit A Higher or Lower Speed Rated Tyre

  • When choosing your tyres and reviewing your speed rating we advise you keep the same tyre speed rating that is currently on your car. However if you are looking to add a lower speed rating we would advise against this, you can make your insurance null and void.

    If you’re looking to add a higher speed rating, then this is possible, but this may result in a rougher ride making your journey less comfortable.
