Test Summary
As we said at the onset - the Ultra-High Performance All Season category has a lot of variability to it, but also a lot of similarities. In other words: there's a lot of gray, where the margins separating one tire for another can be slim. The category itself sits on edge of other groups of tires - not quite touring, not quite Max Performance, but expected to maintain the attributes of both, to compete almost, with both - and if the demands aren't heavy enough, it should be drivable in the winter too! It's a lot. Some of the tires over-index toward raw performance, wet driving, comfort, sound deadening. It's tough to find any that are truly good at everything. That's a large part of what makes finding the right tire so tricky and why testing, to find those minutia, those differences, is ultimately so important.
Continental's ExtremeContact DWS 06 Plus serves as an interesting "best" for this test. It's a good tire for the category, great even, the kind of tire that can be called a benchmark - but it doesn't dominate in an obvious way. It isn't the best in the winter, or the fastest, it doesn't have the most traction, it doesn't have the liveliest steering, but it put everything together really well to create an experience that feels balanced and holistic for a UHPAS tire. Conversely, Pirelli's P Zero AS Plus 3 was kind of a shocking stand-out here. It is fast, it is stable, it is comfortable, it just does it all. Well, mostly. For wintertime driving, it's just average - there are better options (and certainly worse ones), but it doesn't have as much of a command of the season as it does the rest of the year. It isn't surprising: Pirelli has a strong legacy and the latest in a series, after years of iterative tweaks to improve their tire line, being better than its predecessors is normal, expected even - but to have so little in the way of weaknesses, to balance comfort and performance the way it does is truly laudable.
The Bridgestone Potenza Sport AS makes an interesting case for itself here as a niche option - it was certainly not one of our top performers in the dry or the wet, not even close - but in the snow, it was so good compared to everything else in the test that it deserves to be in the conversation. It's a nice tire to drive on-road too, so for drivers concerned primarily with those two things, it's a compelling consideration. Next, the Michelin Pilot Sport All Season 4 is unquestionably a successful tire, and it has years-worth of testing, reviews and feedback to validate it. Time and competition have caught up to this venerable performer though - it was little surprise this round of testing, showing off a very good UHPAS tire that has just been narrowly outclassed by progress. It's capable rain or shine or snow, even if it comes at some sacrifice to its comfort.
The General G-MAX AS-07 is very true to its manufacturer's "general" namesake. It is exactly that: a generalist. It's good in most respects, a pleasant experience on the road, though particularly agile and alive during dry laps, with best-in-test braking. It's just a little bit of a step back from the others with water on the asphalt, or snow on the road, but even competing with premium tire options in this category is worthy of note. Vredestein's Hypertrac All Season is another tire that did not really find a way to stand out positively outside from its winter performance - it was appropriate for the category on the road, pleasant to drive, but its performance never rose to the level of truly exceptional. It was a similar story with BFGoodrich's g-Force COMP-2 A/S PLUS, a mouthful of a tire name, but relatively simple to understand once we drove it. It's fairly well-balanced overall and doesn't give up too much comfort on the road. The steering is quite nice as well. Both its credit and its detriment: it's neither great in any one discipline or terrible in another. It's just a pretty good tire with better and worse options around it.
The Falken Azenis FK460 A/S is a tire that made for a good commuter experience, with appropriate noise mitigation for the category, decent steering and composure over imperfections that let it absorb the unpleasantries of travel. It didn't find a way to stand out on the track, or in the snow - at least not positively. It was capable enough, perhaps compared to grocery-getter touring options, but in this highly competitive category, limits were hit earlier and more often than many of its rivals, resulting in underwhelming performance. Finally, Cooper's Cobra Instinct, one of the strongest outright upper-case "Performance" tires we looked at this group. If the only parameters we looked at were objective scores in warm weather, it's an easy recommendation: the fastest laps and strongest braking in the wet, nearly as capable in the dry, with ample traction available everywhere. However, as an all-season choice, winter performance absolutely has to be part of the discussion - and it was a serious handful by every cold-weather metric. For drivers that don't experience winter at all and don't mind a lack of refinement on the road compared to other category options, it's still good, but it fills a niche case.
