Passenger Car Tire Tests

There's a lot of tires 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 tires chosen for this test have been through a 51 tire wet and dry braking pretest. This means the tires included in this test are some of the best tires available on the market, had Auto Bild included some of the worst tires in the pretest, the gap between the best and the worst tires overall would have been much larger.

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

As you would expect, the track day tires 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 tires 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 tire testing, with the epic German publication Auto Bild already delivering three excellent tests. Of the three, this 20" tire test is perhaps the most interesting of the trio.

For this investigation, Auto Bild have bought eight 245/30 R20 tire 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 tires in wet and dry braking test to decide which twenty tires make it through to the full summer tire test. In 2018 they have used the popular 195/65 R15 summer touring tire size.

The spread of dry braking results was higher than usual this year. The best dry braking tire 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 tire 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 tires, 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 tire.

In 2018, German test body ADAC have tested sixteen 205/55 R16 summer tires, and fourteen tires 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 tire test of 2018 is rather unique. German publication Auto Zeitung have tested six summer tires and three all season tires all in the same test, and while it's going to make the Tire 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 tire types.

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

While studded tires aren't suitable for the UK climate, they are the best way of staying mobile in extreme winter conditions. Each tire can have hundreds of studs, which bite into ice with far more grip than a studless friction winter tire can give. There are of course drawbacks to studded tires, they're very noisy, and they give up a lot of dry and wet performance when compared to a European winter tire, 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 tire 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 tires, and put the tires through the normal dry, wet and snow testing.

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

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

Should this be the case? Michelin have been making alot of noise recently regarding the negative impact of having to scrap a tire 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.

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

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

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

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

Fifty winter tires 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 tire test!

The 2017 Auto Bild winter tire test started with fifty 225/50 R17 winter tire patterns which Auto Bild tested for wet braking performance, and then dropped the worse twenty tires 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 tires to be dropped. This left twenty winter tires which Auto Bild regarded as the best winter tires 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 tires as bad tires, but three in particular rose to the top.

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

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

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

Issue 1,495 of the weekly UK publication Auto Express contains their 2017 winter tire test!

This year Auto Express have tested eight winter tire patterns in 225/45 R17 using a VW Golf in the dry and wet, and an Audi A3 in the snow. 

Auto Express have previously asked us to keep our coverage of their tests to a minumum, so below is a summary of what went on. The full results can be found on the Auto Express website, which we will link as soon as they're online.

Overall, with just 3.9% covering the eight tires on test, it's getting closer every year at the top.

The German publication Auto Zeitung have just published their 2017 all season tire test, and it might be the most UK relevant tire test we've ever seen.

First, they're testing in the most popular 205/55 R16 size using a FWD Audi A3, which represents a large slice of our car market. Then, they've managed to include ten all season patterns, which is more than most all season tire tests manage, but the icing on the cake is the winter tire included for reference is the multiple award winning Continental WinterContact TS 860.

There's one more summer tire test left to cover in 2017, and this time it's the American publication Car and Driver testing five 245/40 R18 maximum performance summer tires using a BMW 430i.

The first winter tire test of 2017 has been published! The German publication Auto Motor und Sport [AMS] have tested ten ultra high performance winter tires in 225/40 R18. This extremely popular 18" tire sizes is fitted to performance saloons such as the Audi A4, Skoda Octavia VRS, and the 232 bhp BMW 430i Grand Coupe used for this testing.
