Tyre UPD
The Oxford English Dictionary suggests that the word derives from attire, while other sources suggest a connection with the verb to tie. The spelling tyre is used in the United Kingdom, Ireland, and most current and former Commonwealth nations after being revived in the 19th century. Both tyre and tire were used in the 15th and 16th centuries. The United States did not adopt the revival of tyre, and tire is the only spelling currently used there.

Low rolling resistance combined with good wet grip, reduced rolling resistance and minimal CO2 emissions - these are the requirements for the tyre that has been specially developed for electric vehicles. However, these are properties that are also important for combustion tyres.
EU tyre labelling rules help consumers make an informed purchase decision when they replace their tyres, as the label highlights the performance of the tyre on issues relating to fuel efficiency, safety and noise. At the same time, the labels drive manufacturers to innovate and strive to have their tyres classified in the top classes in the different categories.
New labelling rules, applying from 1 May 2021, are set out under Regulation (EU) 2020/740. This replaced the previous Regulation (EC) No 1222/2009, applicable from 2012, that first introduced the obligation of labelling car and van tyres. The new rules are extended to cover bus and truck tyres, and introduce options to show if the tyres are suitable for use in severe snow conditions or in extreme climatic situations.
Different tyres can have different rolling resistance for a number of reasons, including the design and structure but also the tread compounds (amount of silica or carbon black). The tyre pressure also affects rolling resistance, as a pressure lower than prescribed results in higher rolling resistance. For all tyre manufacturers, the challenge is to find the lowest rolling resistance that is not detrimental to other parameters, in particular safety.
Low rolling resistance tyres that are properly inflated can have as much as a 10% savings impact. This provides financial savings in terms of running costs or, for electric vehicles for example, enables the driver to cover a further distance before refueling or recharging. The rolling resistance class ranges from A (most efficient) to E (least efficient). The higher the energy class, the lower the rolling resistance. (The previous label had a range from A to F).
The wet grip class is a critical safety feature, relating to how a tyre can brake on wet roads. Tyres are rated A (the shortest braking distance) to E (the longest braking distance). The difference in each category can mean an extra 3-6 metres on the stopping distance.
Standardised tests are used to assess the performance of tyres in all the 5 parameters indicated on the label. Only tyres reaching a predetermined minimal performance level can carry the snow or ice symbol. National authorities perform random controls to check the accuracy of the performance levels.
Tyres need to meet specific requirements to be placed on the European market, as outlined in Regulation (EC) No 661/2009 on the general safety of motor vehicles. This legislation refers to the same testing methods for the same parameters on the tyre label and sets the minimal requirements for efficiency, safety and health protection.
As tyres have continuously improved in performance, and the requirements on the minimum performance level that can be placed on the EU single market have become stricter, tyres with the worst performance have progressively been outlawed. Therefore tyres with an energy class worse than E, with a wet grip class worse than E or with a noise class worse that B are banned from the European market.
Welcome to the home of the leading organisation respresenting the tyre and rubber recycling industry in Europe. ETRA is the only pan-European body that represents the independent tyre recycling sector in Europe. ETRA represents the industry in Brussels and is a key co-ordinator in a number of research Projects, assisting in joining partners, applying for funding and working to bring new solutions to old problems, bringing research and industry together to target high value solutions. ETRA is involved in developing a wider awareness of tyre recycling and the uses to which tyre derived materials can be put to. Driving the recycling process up the hierarchy towards higher value projects. Read more About Us.
ETRA organises a number of events each year with the aim of developing awareness of the potential of tyre derived materials as new raw materials as an alternative to using valuable natural resources, or as the base raw material for new ways of producing high value products such as Silicon Carbide, for example. A key area of interest is in the use of recycled rubber materials in civil engineering and this is highlighted at the Flex in the City seminars.
Tyre Reviews is the leading source of independant tyre information in the world. Every year, Tyre Reviews conducts detailed summer, all season and winter tyre tests, which can be found in the tyre test section
I'm going to try and keep this as condensed as I possibly can as we have 13 sets of tyres in this test including the newest and best from Continental, Michelin, Hankook, Pirelli, Bridgestone, Vredestein, Kumho, Toyo, Nankang and more! This should also be the world's first test of the Continental PremiumContact 7!
So, which all season tyre is best for YOUR own needs? To find out Tyre Reviews has ten of the most popular all season tyres on the market, and will be testing them in the snow, dry and wet, noise, comfort and rolling resistance!
The tyre size I'm testing is massively popular 225/45 R17, and while there might not be any new names in the test this year, a different size and different testing location means we're likely to get some interesting results! The Michelin Crossclimate 2 stormed to victory last year in 16", will this year be any different?
In this test we'll be testing nine of the most popular all terrain tyres to see which has the most grip in the dry, wet, AND offroad, and also to see which uses the least gas, and which has the best comfort and lowest noise in the real world. Basically, everything you'll ever need to know about these all terrain tyres!
To find out which of these new ultra high performance tyres are best, I use a VW Golf GTI wearing 225/45 R17 tires and test the dry, wet, comfort, noise and rolling resistance of nine sets of performance tyres, to see if the new PS5 or Asym 6 can retain their crowns, or whether another brand of tyre will prove to be best!
First up, some general information to clear up some confusion online. This tyre is not a replacement for the Michelin Pilot Sport 4 AND 4S. The Michelin Pilot Sport 5 (PS5) directly replaces the Michelin Pilot Sport 4 (PS4), and while there's been no official announcement about the replacement of the Pilot Sport 4 S (PS4S), it is likely this will be replaced at some point in the future.
The "non-S" version of the Pilot Sport summer tyre range has always been aimed at smaller wheel sizes, and is slightly less performance orientated than the "S version". As an example, in Europe the Pilot Sport 4 was available from 16" to 22" wheel sizes, and aimed at the segment of cars and SUVs which need less ultimate performance, and a little more comfort.
If you're reading this article I'm 100% sure you will already know all about the Michelin Pilot Sport 4 S, which is still, after 6 years, one of the best ultra high performance tyres you can buy today.
The concept for the test seems relatively straightforward - get a bunch of the best performance tyres on the market and test them against the newest ultra low rolling resistance / EV tyres, the Michelin e.Primacy, the Falken eZiex and the Pirelli Scorpion Elect.
As usual, all the tyres were tested in the dry and wet, and had their rolling resistance and noise / comfort levels graded, but as this category of tyre is also intended for some "light off-roading" they tested the twelve SUV tyres in mud, sand, dirt and even on wet grass! This means this really is the best test this year you show you what the best tyre is for your SUV!
The biggest advantage of an Autobild tyre test? They include a wear test, this year done on a machine, so scroll down the page to see each tyres estimated mileage and take note of how that affects the overall result!
The 2023 Auto Zeitung Performance Summer Tyre Test included nine of the very best UHP summer tyres in the popular 235/35 R19 tyre size, and also included the Michelin CrossClimate 2 all season / all weather tyre so show us how one of the best all season tyres compared to some of the best summer tyres. The test car was a 280bhp Ford Focus ST which will give the summer tyres a good stress test, let alone the all seasons!
It's the 50th anniversary of the ADAC tyre test, and to celebrate the German automotive body have tested fifty summer tyres in the popular 205/55 R16 tyre size, and have included wear testing for every tyre!
There's a lot to unpack in this test, so we'll dive straight in! Headline notes, there are two Michelin tyres in this test, the Michelin Primacy 4+ and the energy saving Michelin e.Primacy, the Continental on test is not the new PremiumContact 7, it's the previous model, the Continental PremiumContact 6, and Continental also have the new Continental UltraContact in the test, which is meant to be a lower rolling resistance and higher mileage tyre for those who drive a lot of distance!
For their 2023 summer tyre test, AutoBild have started with fifty 225/45 R18 tyres, mostly ultra high performance tyres but also some touring bias rubber, and put them through a huge dry and wet braking test.
As always, the real fun will be published in the full review in a few weeks where the top twenty tyres from this test will be put through a full examination, but this braking data does give us some interesting insights. 041b061a72
