This year Auto Bild have covered both 19 and 20" UHP tyres, and while we've covered the 20" test already, we delayed covering the 19" test for a few weeks.

In those few weeks, Sport Auto Magazine released their 19" tyre test, and it uses exactly the same 245/35 R19 and 265/35 R19 tyres, on the same BMW M2, and tests the same six UHP tyres at the same location.

The logical question would be why publish this version of the test, as the results should be exactly the same? Well, they're not. Whether it be down to driving style, test parameters or just the weather on the day, Sport Auto and Auto Bild have managed to come up with two different test results using the same vehicle and tyres, proving just how close the very best tyres on the market are.

There's a lot of tyres in the 2018 Auto Bild 195/65 R15 test, so we'll keep the intro as short as possible and let the data do the talking.

It's worth keeping in mind, the twenty tyres chosen for this test have been through a 51 tyre wet and dry braking pretest. This means the tyres included in this test are some of the best tyres available on the market, had Auto Bild included some of the worst tyres in the pretest, the gap between the best and the worst tyres overall would have been much larger.

The latest trend of combining two tyre tests into a single result seems to be continuing, with the brilliant German publication Sport Auto combining six ultra high performance tyres and three track day tyres into a single test!

Using a BMW M2, Sport Auto used the M2 OE sizes of 245/35 R19 front and 265/35 R19 rear, and objectively tested wet and dry performances while also scoring the subjective handling and feel of a tyre.

As you would expect, the track day tyres dominated in the dry, were the weakest in the wet, and generally had the highest rolling resistance and were the nosiest. Some of the road tyres were surprisingly close to the track day rubber during dry testing, and they were leagues ahead in the wet testing.

2018 is setting up to be an excellent year for tyre testing, with the epic German publication Auto Bild already delivering three excellent tests. Of the three, this 20" tyre test is perhaps the most interesting of the trio.

For this investigation, Auto Bild have bought eight 245/30 R20 tyre patterns and placed them through the usual array of wet and dry tests using a Mercedes E Class.

While the internet favourite Michelin Pilot Sport 4S takes its traditional top spot, there is a strange result for the Continental Sport Contact 6, a great result for the ten year old Goodyear Eagle F1 Asymmetric 2 (not 3!), and Bridgestone make a return to tests with the old Potenza S001.

Read on for the full results!

Every year Auto Bild test over fifty tyres in wet and dry braking test to decide which twenty tyres make it through to the full summer tyre test. In 2018 they have used the popular 195/65 R15 summer touring tyre size.

The spread of dry braking results was higher than usual this year. The best dry braking tyre on test, the Hankook, stopped the car from 62mph in 34.5 metres, and the worse 42.4 metres. This 7.9 metre difference might not sound like a huge amount, but it is the difference of stopping or hitting an object at around 26 mph!

The spread in the wet was even larger. The Bridgestone was best in the wet, stopping the car from 50 mph in 34.3 metres, where as the worst tyre on test took a massive 17.6 metres further, totaling 51.9 metres. That's over 4 car lengths further and a huge residual speed at time of accident.

In 2018, German test body ADAC have tested fourteen 175/65 R14 summer tyres, and sixteen in the larger 205/55 R16 size.

In this 175/65 R14 test, the mid range brands dominate! Falken impressively win the test and continue their run of recently form with the SN832 Ecorun having a very balanced overall performance. The Continental owned brand Semperit finishes in second place, owing to an excellent wet performance, and third place was the best result a premium manufacturer could manage with the Dunlop proving to be a well balanced tyre.

In 2018, German test body ADAC have tested sixteen 205/55 R16 summer tyres, and fourteen tyres in the smaller 175/65 R14 size.

In this 205/55 R16 test, premium manufacturers take the top three places. Michelin lead the way, having the lowest wear on test and proving to be excellent in the dry, Bridgestone have a surprisingly strong performance in the wet to score second place overall, and Continental have a very balanced showing for the last of the podium spots.

The first tyre test of 2018 is rather unique. German publication Auto Zeitung have tested six summer tyres and three all season tyres all in the same test, and while it's going to make the Tyre Reviews version of the result at the bottom of this page read slightly wonky, it's a really interesting way of comparing the dry and wet performances of the two tyre types.

Keep in mind, the nine tyres were only tested in the dry and wet, there was no snow or ice testing to highlight the all season tyres year-round abilities. This means this test should just be looked at to see how the all season tyres compare to the summer tyres in summer conditions, rather than making a purchase decision for year-round motoring.

While studded tyres aren't suitable for the UK climate, they are the best way of staying mobile in extreme winter conditions. Each tyre can have hundreds of studs, which bite into ice with far more grip than a studless friction winter tyre can give. There are of course drawbacks to studded tyres, they're very noisy, and they give up a lot of dry and wet performance when compared to a European winter tyre, but in climates such as Russia and the Nordic countries where you are likely to be driving on ice for weeks at a time, there's little alternative.

We're a little bit late with this one, as it's likely the UK has had most of its bad weather for winter 2017/18, however we can't resist covering a winter ultra high performance tyre test, especially when they use a RWD Toyota GT86 as the test car!

For this test, Sport Auto magazine fitted the GT86 with ten different patterns of 225/40 R18 sports winter tyres, and put the tyres through the normal dry, wet and snow testing.

Everyone knows tyre performance changes with wear, with the biggest change in tyre performance coming from all season and winter tyres in snowy and icy conditions.

The drop in performance can be so vast after 4mm that certain countries where "three peak mountain and snowflake" tyres are a legal requirement for winter driving, they can lose their legality after 4mm, meaning you only get to use half of your tyres tread.

Should this be the case? Michelin have been making alot of noise recently regarding the negative impact of having to scrap a tyre with half its tread life remaining, and their arguments are compelling. Not only are you costing the customer more, but you're also causing a much higher negative environmental impact by doubling natural resourse usage and doubling waste.

For 2017, the "All Road" edition of the German publication Auto Bild has tested ten 225/55 R17 winter tyres. This size is commonly used by compact crossovers, such as the BMW X1 used in this test.

The biggest interest in this test was the Chinese budget winter tyre from Pace. With the most expensive set of winter tyres costing 660 euros at time of test, the budget Pace tyres were a full 400 euros cheaper, at just 260 euros. Are the savings worth the performance drop? Read on below to find out.

The 2017 Auto Express all season tyre test is a wonderful mix of eight 205/55 R16 all season tyres, the Dunlop Sport BluResponse summer tyre and the Continental WinterContact TS860 winter tyre.

A new feature for 2017 is wet testing at over, and under the magic 7c mark the tyre manufacturers recommend we change our tyres at.

For 2017 the Polish publication AutoCentrum has tested eight studless winter tyres in 185/65 R15. As with the other winter tyre tests we've featured across 2017, AutoCentrum tests the winter tyres in the dry, wet and snow, but also includes ice testing, a first for 2017.

Six of the tyres on test are European winter tyres which are available to the UK market, and two of the tyres (Debica Frigo 2 and Sava Eskimo Ice) are full nordic friction winter tyres, so it should give us a good overview of how these two different types of tyres perform, and why Nordic winter tyres aren't suitable for the UK market.

Fifty winter tyres have been put through wet braking tests, with the top thirty also tested for snow braking performance. Only the top twenty have gone through to the full Auto Bild winter tyre test!

The 2017 Auto Bild winter tyre test started with fifty 225/50 R17 winter tyre patterns which Auto Bild tested for wet braking performance, and then dropped the worse twenty tyres from the test.

The next phase was testing the remaining thirty patterns for snow braking, which was then combined with the wet braking distances to allow the ten worst tyres to be dropped. This left twenty winter tyres which Auto Bild regarded as the best winter tyres on the market, and deemed worthy enough to take through to the full testing.

As ever with Auto Bild testing, they undertake all the usual dry, wet and snow testing, but also including important factors such as wear and cost per 1,000 km, which a lot of tests are unable to include.

The results as closer than ever, and you'd be hard pressed to classify any of the top 10 tyres as bad tyres, but three in particular rose to the top.

Sadly there's very little data available for this 235/55 R17 SUV tyre test conducted by the European motoring bodies ACE / ARBO / GTU, nor are Michelin featured, but it's still worth a read if you drive a crossover vehicle such as the Ford Kuga or Volkswagen Tiguan which uses this tyre size.

This year the German motoring orginisation ADAC have tested winter tyres in 195/65 R15 and 215/65 R16.

Unusually for a winter tyre test, Continental faulter in this 215/65 R16 SUV tyre size, only finishing seventh overall. This leaves the door open for Dunlop to take first place with the Winter Sport 5 which proves to have a very balanced all round performance with no glaring weaknesses.

BF Goodrich finished in a very strong second place, winning the majority of the test categories but missing out on the top spot due to a slightly weak wet performance, where as the third placed Goodyear UltraGrip Performance Gen-1 proved to be extremely strong in the wet, but a little disappointing on snow.

This year the German motoring orginisation ADAC have tested winter tyres in 195/65 R15 and 215/65 R16.

The 195/65 R16 winter tyre test continues Continentals winter dominance, with another win for the Continental WinterContact TS860. 

The 2017 Auto Bild all season tyre test has tested ten 205/55 R16 all season tyres touring tyres, using a VW Golf. This is also the first test to include the new Continental AllSeasonContact tyre.
