Auto Bild are the European leaders in tire testing, and go to lengths with their tests no other publication can. Firstly, to select the sixteen all season tires in this test, they placed thirty two sets through a dry and wet braking test with the top sixteen qualifying, ensuring these sixteen are some of the very best on the market.
Secondly, Auto Bild contracted out a very expensive wear test, which consisted of 12,000 km for each set of tires in real world conditions, then extrapolated the data through to 1.6mm. This allows the testers to put the total mileage covered against the purchase price to work out which tire is best value. More on this later in the article.
If you've already seen the 2021 Tire Reviews All Season Tire Test, you will find the results of this test familiar in parts, and surprising in others due to the different ranking of the tires across the two tests. As these differences can be confusing to tire shoppers, I'd like to talk about why these differences exist.
Firstly, the Auto Bild test uses a different scoring weight to Tire Reviews, and they convert results into points and then into a final point based grade. Unlike Tire Reviews, some of the calculations made are not public, so it's difficult to work out the exact reason each tire came where, but they do provide most of the raw data which is very useful.
Secondly, Auto Bild have tested and scored on more categories, including wear and the overall value of the tire which is an important criteria Tire Reviews does not.
Thirdly, the test conditions were different. This test used 225/50 R17 on a heavy RWD BMW 3 Series, and tested the dry and wet performance of the tires in warm summer conditions (22c+). Tire Reviews used 205/55 R16 on a lighter FWD VW Golf and tested the dry and wet performance of the tires at a cool 4c. Tire Reviews also snow tested the traditional way outdoors during winter, whereas Auto Bild used a much smaller indoor snow facility.
Lastly, the grip surfaces were different. Tire Reviews tested on a track with a surface grip similar to a new tarmac road. Auto Bild like to use low grip surfaces to expand the differences between the tires, especially in wet braking which can sometimes be artificially low.
Now you understand the differences in testing, what are the differences in results?
There are four important changes between the two tests, the Goodyear Vector 4 Seasons Gen-3 won this test instead of fifth in Tire Reviews, the Michelin CrossClimate 2 placed seventh here and won the Tire Reviews test, the Pirelli Cinturato All Season SF2 dropped from second in Tire Reviews to fourteenth in this test, and the Nokian SeasonProof scored well in this test overall.
The Goodyear result is easy to explain. In the Tire Reviews test, the 16" Goodyear struggled in wet braking at both temperatures tested. Had it not, it would have been one of the best tires on test (noted in the article), and in this test it performed as expected. It's difficult to understand why the Goodyear didn't perform well in the Tire Reviews wet braking tests without further testing, but from all the other testing the tire has done, it seems like that was the outlier.
The Michelin CrossClimate 2 was marked down for two reasons in Auto Bild. Firstly, it scored relatively poorly in wear, and when you calculate value based on purchase price it worked out to be one of the worst value tires on test - this is not something Tire Reviews scores on. Secondly, the French tire struggled in the wet in both tests, which might be down to the lower grip surfaces used, or a function of the vehicle and size combination.
The Pirelli Cinturato All Season SF2 lost a lot of points in this test due to the worst wet braking and wet handling in this test, compared to the Tire Reviews test where it had reasonable wet performance. This is harder to explain, but could again be a function of the low grip surface of the tracks or the tire size differences.
Finally, the Nokian SeasonProof actually had similar results between the tests, it just seems Auto Bild put a much higher weighting on snow performance than Tire Reviews does. Plus, the high wear and competitive purchase price made this tire the second best in terms of value on test, which is worth a lot of points promoting it in this test.
To conclude, there are differences in tire test results all the time, and I understand that it's frustrating for the customer especially when new tires like the CrossClimate 2 and SF2 have different results between the first big tests they feature in.
In the incredibly complicated world of tire test, the goal of Tire Reviews has never been to say "our data is right, ignore everyone else", instead it is to give you as many data points as possible to allow you to make your own purchase decision. I still encourage you do that for future purchases.
The positive is there is a lot of synergies between tests too! The Continental AllSeasonContact performed well in both tests, as did the Vredestein product, and the third placed Hankook in this test also performed well in the Tire Reviews test last year.
As we've become accustomed to in all season tests, the Michelin CrossClimate 2 led the way in dry braking and dry handling, but this time some of the other all season tires had closed the gap.
Wet testing highlighted three brands as having good wet performance, Vredestein, Goodyear and Falken took the top three spots in both wet braking and wet handling.
The summer tire had a surprisingly large lead in the straight aquaplaning test. The curved aquaplaning data can be found in the results table below.
All three snow tests were led by Nokian, who have a strong history with excellent winter products. Michelin have improved on the snow performance of the CrossClimate+, with the CrossClimate 2 scoring well in all three tests, and Firestone and Continental also performed well in the winter conditions.
The Pirelli Cinturato SF2 had the lowest external noise on test in a group which was only split by 3db.
Of the leading tires overall, Michelin and Pirelli had very low rolling resistances.
The three charts below cover the calculated total tread life of the tire based on 15,000km on the road, then calculated down to 1.6mm, the purchase price of the tires in euros at the time of publication (this figure can vary between markets and times of year) and then the value of the tire, based on how many euros you pay in wear based every 1000 miles.
Michelin, long known for some of the best wear on test, seem to have dropped some mileage from the new CrossClimate 2, which could only finish mid pack with an estimated tread life of 40,000km. Instead, the Kumho Solus 4S HA32 proved to have the lowest wear of the group, calculated to cover over 54,000km with the Nokian SeasonProof in second at a very reasonable 51,000km.
Perhaps most impressively, given the high grip in nearly all tests, was the Goodyear Vector 4Season Gen-3 which promised to cover 50,000km, with it's main rivals from Continental and Hankook only expected to cover 43,000km and 34,000km respectively.
While the wear performance of the top tires on test were impressive, the difference in value was even more apparent, with the high priced Michelin one of the worst value tires on test with the group leading Kumho and Nexen products offering nearly half the price per kilometer travelled.
The Goodyear offered the best best value of the leading tires overall.
