The German publication Auto Bild have published their third tire test of 2017, this time testing nine UHP tires in 245/40 R18 using an Audi TT. Without a budget tire included in the test, this is one of the closest tire tests we've seen in years, and highlight just how close the latest generation of tires have become in terms of raw performance.
Wet
In the wet, the Michelin Pilot Sport 4 came out best overall. It won the aquaplaning tests and was joint fastest during the wet handling lap. The Firestone tire lost both categories.

Under wet braking, the Michelin only managed sixth position, but when you consider the gap between the test winning Dunlop and sixth placed Michelin was just 0.4 meters, you realise the order of the top tires could fall within the variance of the testing. The now-dated Continental Sport Contact 5 struggled, but not as much as the Firestone tire, a full ten meters behind the winning Dunlop.
Wet Braking
Spread: 10.10 M (21.8%)|Avg: 48.04 M

Dry
As in the wet, the Michelin was the fastest tire in the dry, with Vredestein a close second.

The dry braking test verified Vredesteins dry ability, with Vredestein convincingly winning the test. Firestone once again finished last, rounding out last place in every test of grip performed.
Dry Braking
Spread: 2.20 M (6.1%)|Avg: 36.56 M
Dry braking in meters (Lower is better)
Dry Braking: Safety Impact: Best vs Worst Tire
The rolling resistance test was won by Goodyear, with the first five places close enough not to make a huge impact in overall fuel use. The excellent dry grip of the Vredestein does have a trade off, the Ultrac Vorti had the worst efficiency of all tires on test.
Rolling Resistance

Estimates based on typical driving conditions. Rolling resistance accounts for approximately 20% of IC vehicle fuel consumption and 25% of EV energy consumption. Actual savings vary based on driving style, vehicle weight, road conditions, and tire age. For comparative purposes only. Lifetime savings based on a 40,000km / 25,000 mile tread life.
The quietest tires on test were Hankook and Vredestein. Firestone once again ranks last, but is the cheapest tire on test.

Results
Below are the overall results. Auto Bild place a higher score weighting on the wet results, which is why the total scores aren't in sequence with the order of results.
Very good handling on dry and wet surfaces, precise steering response, good feedback and short braking distances in all conditions. High level of comfort
