Tyre testing is incredibly complicated to conduct, and one of the most difficult parts of testing is good repeatability.

Take for example wet braking. To get the wet braking distance of a tyre, you don't just do the braking run once, you do it 6-8 times, delete the outliers then average out the results. Even on the most expensive test facilities in the world, with the most perfect sprinkler systems and perfect tarmac, you rarely get the same distance twice as there are so many variables, which means when you use a less than state of the art facility, results can be surprising.

This brings us on to this test by the Italian publication "al volante". 

Here at Tyre Reviews, we receive many different questions about tyres, but one question that comes up more than most asks if modern retreaded tyres, sometimes called "retread" or "remoulds", any good?

While we've not been able to test ourselves, tests from many years ago indicate that retreaded tyres don't perform as well as even a budget tyre. Car tyres typically aren't designed to be retreaded (commercial bus and lorry tyres are), so the retreading process can leave you with not only poor performance, but a product that could be classified as unsafe.

Naturally in the past few years there have been improvements in the car retreading process, and one brand in particular, King Meiler, has established a name for itself as "the" retreading brand.

To find out whether a modern retread can match a premium, or even a budget tyre, the Polish magazine "Motor" have tested the King Meiler HPZ against the premium Continental PremiumContact 6, and a much cheaper Debica Presto HP.

If you like detailed and confusing tyre tests, you're in for a treat! The 2020 Sport Auto tyre test has tested ten 245/35 R19 tyres, using a Mercedes AMG A45 S, and is confusingly amazing!

Why is this confusing? Well, they've tested three different types of tyres in the single test! The first group is the more "regular" ultra high performance tyres, which includes the Goodyear Eagle F1 Asymmetric 5, Nokian PowerProof, Vredestein Ultrac Vorti, Toyo Proxes Sport, and strangely, the Continental SportContact 6. They've also tested two "UUHP" tyres, the Michelin Pilot Sport 4S and the new Goodyear Eagle F1 SuperSport (which is the group we believe the Continental SportContact 6 should be included in as the PremiumContact 6 is the rival to the Asymmetric 5), and three track day tyres, the Michelin Pilot Sport Cup 2, the unreleased Bridgestone Potenza S007 RS, and the Giti GitiSport GTR3.

Each year, the wonderful Swedish publication Teknikens Värld performs a summer tyre test in Sweden. Their 2020 test covers ten 225/50 R17 summer tyres, including the first test of the brand new Goodyear EfficientGrip Performance 2!

The unique Swedishness of the test means they don't perform dry handling, but instead the "moose test" which involves a sharp lane change at speed. Sadly, we can't database this, but you can see the results of the test in the commentary at the bottom of the page.

The 2020 Auto Motor und Sport summer tyre test tested eleven 225/45 R18 ultra high performance tyres using a BMW 3 Series.

While the group overall was extremely close, the winning Goodyear Eagle F1 Asymmetric 5 and second placed Michelin Pilot Sport 4 were almost inseparable overall, with the Goodyear narrowly taking the overall win.

Ultra high performance tyre tests always make us happy, and Auto Bild do some of the best. For 2020, AutoBild have tested nine sports tyres in the staggered 245/35 R19 and 265/35 R19 sizes using a Mercedes Benz C63 AMG.

Like our UHP tyre test in 2019, Auto Bild have tested the very three best UHP tyres on the market, the Continental SportContact 6, Goodyear Eagle F1 SuperSport, and Michelin Pilot Sport 4S, along with some of the other well know UHP tyres from Hankook, Vredestein, Falken and other brands.

Following on from the fifty tyre braking shootout, Auto Bild have more thoroughly tested the best twenty 245/45 R18 summer tyres using a RWD BMW 5 Series.

The top three tyres should come as no surprise, with Continental, Goodyear and Michelin proving to be the most rounded tyres on test. 

The Continental Premium Contact 6 and Goodyear Eagle F1 Asymmetric 5 drew for first place. As we found with our video comparison, both the Continental and Goodyear tyres offer sporty handling, good levels of comfort, and short wet braking. Both tyres also topped the Wear testing, and thanks to a reasonable purchase price, offered some of the best value on test.

The 2020 Auto Zeitung summer tyre test has been published, and as usual they've tested a really interesting mix of twenty tyres in the popular 225/50 R17 size.

As 225/50 R17 tyres generally bias towards comfort rather than outright sporty performance, AZ tested with the new brand BMW 3 Series, and performed the usual array of  thirteen dry, wet, comfort and economy tests.

The talented guys at ACE Europe have just released their first summer tyre test for 2020, and interestingly they've tested nine 215/55 R17 summer tyres from the mid range sector of the market!

While ADAC doesn't provide its readers with raw data from their testing, their yearly tyre tests are some of the most influential in the world. This year they've tested sixteen 225/40 R18 car tyres, and twelve 235/55 R17 crossover SUV sizes. For the 225/40 R18 test, there are few surprises.

Continental and Michelin tie for first place with the PremiumContact 6 and Pilot Sport 4, two tyres we've seen perform extremely well in all testing. It's worth noting that the Continental and Michelin both scored the same in the wear testing, once again showing Continental have got on top of wear.

Every year the German publication Auto Bild performs the industries most comprehensive tyre test by putting a huge number of tyres through wet and dry braking, to find the best twenty tyres to progress through to a full tyre test.

For the 2020 summer season, Auto Bild have tested fifty tyres in 245/45 R18, which gives us an excellent overview of the UHP market for 2020.

In their second SUV / 4x4 all season tyre test of 2019, Auto Bild have tested ten all season tyres in 235/65 R17, and included the usual summer and winter tyre as benchmarks.

The 2019 Auto Center winter tyre test is both good and bad. The positive is that out of ten 205/55 R16 patterns, it only includes two premium manufacturers. This means we get a much better look at the midrange bracket of winter tyres, which is great for those of us who want to save a little money, and all ten patterns on test have been tested for ice braking and traction which is now usually omitted from central European tyre testing.

For their third winter tyre test of 2019, Auto Bild have stepped up the fun and fitted an Audi S5 with eleven sets of 255/35 R19 ultra high performance winter tyres, and included the usual set of reference summer tyres!

Following on from a win in Auto Express, the new Goodyear UltraGrip Performance+ takes its second win of 2019, once again proving to have a near flawless blend of qualities. Vredestein have also continued their run of good results with a very strong second place for the Wintrac Pro. This tyre is significantly cheaper than the premium winter tyres in the UK, so is probably the best choice if you need to save a few pounds.

Are cheap winter tyres safe? To find out, we travelled to Finland, twice, to do snow, ice, wet and dry testing.

All tests were done using two cars, a VW Golf wearing 205/55 R16 tyres, and a heavier, larger Volvo S90 fitted with 245/45 R18 tyres.

For the first time in 2020, Tyre Reviews will be performing its own all season tyre test, but until then, the Auto Bild all season tyre test is the best you can get! Testing ten sets of all season tyres in 225/45 R17 using a BMW 1 Series, and including a summer and winter tyre as reference, Auto Bild have done as thorough a job as ever for their 2019 all season tyre test.

The most notable performances follow the trends other tests have shown during 2019. The new Bridgestone WeatherControl A005 couldn't deliver on the foundations laid by the strong wet and dry braking performance in the shootout test, finishing ninth overall due to a very average snow performance, but more importantly for UK drivers, very high wear.

The 2019 Auto Express winter tyre test has tested ten 225/45 R17 winter tyres, and included a summer and all season product as a benchmark.

The newest winter tyre from Goodyear is shaping up to be an excellent winter product. Thanks to a near perfect all round performance, it wins another tyre test, narrowly beating the established king of winter motoring, the Continental WinterContact TS860.

The ACE / GTU tyre test is always a funny one, as they go to a lot of effort to test the tyres, but then provide no data at all, only the overview scores.

For this reason, we always keep the commentary low, but it's important to have the test results on Tyre Reviews, as the more tests published the better right?

The weekly UK publication Auto Express has just published their 2019 all season tyre test! This year Auto Express tested nine all season tyre patterns in 205/55 R16 using a VW Golf.

As in previous years, Auto Express have included a summer and winter tyre as reference. Shockingly, the summer Continental PremiumContact 5 was the best in dry overall, near the best in wet, and fell apart in snow. Things get more interesting when we compare the winter Continental WinterContact TS860 to the all season tyres on test.

While studded tyres don't have much use in the UK, for parts of the Nordic countries they are essential for safe mobility.

To find out which of the latest studded winter tyres are worth fitting, Swedish magazine Vi Bilagare have tested seven studded winter tyres in 225/50 R17, and included a studless nordic friction winter tyre as a comparison.
