Review Continental Winter Contact Si Vs New Blizzak
From the December 2015 issue
Assuming you don't read Suomi, the language of Republic of finland that sounds like a mashup of Dutch and Klingon, in that location are few road signs you will empathise when you lot're 186 miles above the Chill Circle. But i announcing that Murmansk, Russia, is 188 miles abroad gets your attending, reminding you lot simply how far north y'all are. Murmansk is a Cold War relic on the Arctic Ocean—to Soviet submarine warfare what Greatcoat Canaveral is to spaceflight. These days, the Russian Northern Fleet occasionally moors nearby.
Then another sign nosotros can read pops up on the left: "Test Earth Oy." Oh yeah, we're here to exam some winter tires. Murmansk volition have to wait. We have a cold war of our ain to deal with.
The Test Globe Mellatracks proving grounds is a facility that offers year-circular testing on natural snow, as opposed to the man-made stuff. During winter months it operates like any other automotive proving grounds, but with frozen canals and snowfall-packed fields standing in for the physical and asphalt yous find at more than-temperate venues. In early on jump, Test Globe stockpiles snow, filling its 2 buildings with well-nigh two feet of packed, natural white stuff, enough to last the unabridged indoor-testing season. Nosotros headed upward to the refrigerated covered complex in late summertime, as nosotros wanted this story to appear in time for you to take reward of its findings for the wintertime soon to be upon usa.
The Indoor 1 edifice is a 525-foot-by-52-human foot pole barn of packed snow that includes a lane of Zamboni-maintained water ice. Indoor 2 contains a 0.ii-mile, 30-foot-broad squiggly handling circuit. Both buildings have cooling circuits in the flooring and chilled forced-air ductwork. On our test day, the inside thermometer read -11, equally in degrees Celsius, or 12 degrees Fahrenheit.
But 25 pct of snowbelt drivers fit their vehicles with winter tires, while Quebec and many European countries make them compulsory.
Indoor 1'southward maximum speed is relatively ho-hum: Braking tests on snowfall and water ice are from 18 and 16 mph, respectively, down to 3 mph. The acceleration tests are only the opposite. Eliminating the zero-to-iii-mph range for both going and stopping is a way to test effectually widely varying performance at low speeds on low-friction surfaces, attributable to differences in driver inputs also as ABS beliefs.
Indoor 2 is where the real fun happens. From the air, it looks like a giant hollow Jelly Belly. Its top speed of 45 mph on snow feels similar triple digits in the dry out. Go a corner incorrect or slide also much and you'll hit a strategically placed snowdrift, there to take hold of the car before the Armco does. Because "Indoor 2 subjective handling examination" is a mouthful, we'll merely call it the "snowcross" exam. Between each tire session, a maintenance crew resurfaces the snowfall to continue conditions as constant every bit possible. Too, a control tire laps periodically to normalize results if the track becomes faster or slower.
For this exam we wanted to make up one's mind the all-time-performing studless snow-and-ice tire. As with past tire tests, nosotros deferred to experienced drivers, this time supplied past Test World, for the objective acceleration and braking on snowfall and ice. We also partnered with our hosts for the subjective evaluation conducted on the indoor snowcross circuit and measured in lap times. Our mule was one of Exam Earth's Ford Focuses fitted with 225/45R-17 safety.
These tires rely on their construction, safety compounds, tread design, and what occasionally feels similar magic to generate grip at the contact patch. Almost all tire manufacturers brand a tire in this category, which is targeted mostly at family sedans and hatches. Simply we limited our testing to the heavy hitters: tires from Bridgestone, Continental, Dunlop, Michelin, Nokian, and Yokohama.
Only 25 percent of snowbelt drivers fit their vehicles with winter tires, while Quebec and many European countries make their employ compulsory. This tire war won't have the impact of the real Common cold State of war, but if y'all are amidst the 3-quarters of drivers who don't utilize a ready of cold-weather tires, we hope to change your thinking.
Your Best Foot Backward
No one recommends yous install simply two winter tires. If you must for reasons of price, though, the conventional wisdom is that you want the best shoes (or the to the lowest degree worn) in the rear no matter if you have a forepart-, rear-, or iv-wheel-drive vehicle. To confirm or bosom this bias, nosotros mixed two sets of Michelin tires, winter and all-season [see "Seasoned Perspective," below], and ran a few laps of the snowcross with the all-seasons in front and the winters on the back, and then vice versa. Conclusion: Putting the winter tires on the front wheels was a lot more fun. Not simply was the grip-in-front end car easier to steer and brake, it was also 3.2 seconds quicker around the trivial circuit at Test World. But that lap came with a wallop of oversteer, the kind of rear-end looseness that would catch nearly drivers out and toss them right into the ditch. Putting the winter tires at the rear yielded stubborn understeer, which is way more predictable than the alternative. So if you're going to mix tires, for prophylactic'south sake put your best rubber at the rear.

Extra-load tires are capable of carrying more weight at a college air pressure than a similarly sized tire.
Seasoned Perspective
You may retrieve you don't need winter tires considering your automobile has all-seasons. But, ironically, if you live somewhere that actually has all the seasons, you need winter tires. For perspective on this issue, nosotros asked Michelin for a set of all-seasons, and it sent over its Airplane pilot Sport A/Southward 3. If nosotros were going to buy an all-season tire, information technology would exist this i, because it actually has some serious dry grip in summertime atmospheric condition. But equally good as it is, the Airplane pilot Sport was nearly six seconds off the Nokian's pace on the snowcross, and it didn't come shut to any of the winter tires' braking performances. On the snow, information technology took 5 feet more to end than the boilerplate of the six wintertime tires on the following pages. Five feet may mean the difference betwixt a fender bender and an accident-free winter. Braking distances on snow may exist the best reason to fit a gear up of wintertime tires, and Inuit stoplight elevate racers would practise well to note the extra second of dispatch from iii to eighteen mph.

Last place in this test is like coming in sixth place in the Olympics. Yes, there are better performers, but this rubber is yet pretty amazing. The iceGUARD iG52c is far better in winter weather condition than any all-season tire on the road.
The iceGUARD's largest signal loss came on the snowcross, where it showed the very desirable trait of progressiveness—turning and braking in a linear fashion. Information technology's a calm tire, never losing or gaining grip unpredictably. That said, the iG52c's overall lack of maximum traction put it almost ii seconds behind the quickest tire in the snowcross, which is a massive gap on a 30-second track.
Information technology also fell short in the straight-line tests, taking the fewest points in all just water ice acceleration, where it barely nudged the fifth-place Dunlop. The gaps in this test are, for the most part, modest because of the slow speeds; they would abound exponentially with stride.
The biggest thing the iG52c has going for it is price. It'due south the least expensive tire in the test. Many cramp at the toll associated with winter tires; not just the rubber but the plumbing equipment or the second set up of wheels. That winter-tire utilise extends the life of summer tires is ofttimes overlooked. Certain, soft winter compounds wear faster than summertime or all-flavour tires, but the benefits are well worth the investment, no matter which winter tires you purchase, including this Yoko.
5. Dunlop
Wintertime Maxx

Load: Extra

Dissimilar every other tire in this test, the Dunlop Winter Maxx has an asymmetrical tread design, meaning that, as opposed to a directional tire, it has defended inner and outer tread blocks. Winter tires produce more road noise than summertime tires, and asymmetrical designs are ordinarily quieter. But asymmetrics are more often than not reserved for the "functioning winter" grade, where there's more emphasis on a tire's dry abilities.
Nosotros're non sure its blueprint led to this tire'due south near-basement finish, but the straight-line objective tests don't lie, and finishing concluding in three out of 4 tests is too much to overcome. The worst score came in water ice dispatch, with the Dunlop trailing ane.29 seconds behind the winner. The Dunlop'due south snow braking is impressive, however, with a distance just one-half a foot longer than the Bridgestone and Nokian.
Somehow, with the worst score in all the objective tests but snow braking, the Maxx still turned a pretty quick lap, 29.74 seconds, most tying the second-place finisher. Of annotation: When surpassing the limit in a corner, the Dunlop required some patience in its recovery, and in that location is a pronounced delay from input at the wheel or pedals to reaction at the surface.
Each Winter Maxx is $viii more than the Yokohama. If you're on a budget and averse to road noise, it'south worth considering the Winter Maxx. But if you want more performance, keep reading.

Blizzak WS80

Blizzak is a familiar proper noun, synonymous with wintertime-rubber excellence. We've been putting WS-series Blizzaks, starting with the WS15, on our long-term cars since the product line came to the U.Due south. in 1993. Thus, the WS80'southward quaternary-place cease shocked united states.
Fortunately, the WS80's major highlight is ane of the more desirable traits for a wintertime tire: stopping in the snow. A large office of snow traction, specifically longitudinal accelerating and braking, comes from snow building upwardly and packing in the tread. The resulting snow-on-snowfall contact increases grip, assuasive the WS80 to tie our winner in snow braking. Hydrophilic passages, or holes in the tread that remove the microscopic layer of h2o that exits on ice, helped the WS80 necktie the Conti at midpack for ice-braking scores.
Unfortunately, the WS80 posted the second-slowest snowcross fourth dimension.
We thought it had some of the worst at-the-limit behavior by abruptly losing grip with little progressivity and a lengthy recovery time.
Bridgestone says it invests more than $1 billion a year in research and evolution, and winter tires are a large office of that. But there is a noticeable step upward in functioning from 4th to third in this examination, and we hope Bridgestone'due south engineers will shut the gap with the next-generation WS.
3. Continental
WinterContact Si
Service Description: 94H
Load: Extra

Cost Per Tire: $131

This is the newest tire in the exam and amidst the near affordable. Information technology's an amazing value, falling only 6 points brusk of the winner. Even if y'all take cost out of the equation, it's withal an amazing piece of wintertime equipment.
As with all the other tires here, information technology has thousands of sipes to deed as biting edges on water ice. All the tires feature circumferential grooves (with the exception of the Nokian) and large channels to pump h2o and slush from the contact patch.
Excellent acceleration control exiting corners is a large contributor to this tire'southward second-quickest lap time, and the Continental felt stronger than the second-place Michelin in this regard, just notwithstanding inferior to our winner. The WinterContact also exhibited even and progressive limit beliefs, breaking away and returning to grip predictably via steering and throttle manipulation.
All the same, nosotros had to brake a picayune earlier on the quick part of the snowcross, which lowered overall driver confidence. This was particularly alarming considering the Conti came out of the corners so well and therefore carried greater speed. A lowest-in-test snow-braking score confirms our subjective findings.
Falling short in merely a single subjective measurement, this tire rises to the top tier of winter condom with its accurate steering, well-nigh-best snow acceleration, and attractive cost.

X-Ice XI3

Tire development is an agonizingly irksome process. A Michelin engineer told us recently that, after exiting Formula 1 racing in 2006, the company is just at present trickling that engineering science downwards into its workaday road tires. We've put many sets of XI2s, the XI3's predecessor, on cars in our 40,000-mile long-term fleet, and the difference in feel between the two generations is remarkable.
Subjectively speaking, the XI3 finishes second just to the Nokian. A slight reduction in control versus the Hakkapeliitta in sharper corners indicates that the XI3's foursquare edges, which all the wintertime tires in our test have, don't work quite as well as the Nokian'southward. Laps feel quick but besides quite a fleck looser, requiring a lot more than driver try to keep the car under control. Besides, on-throttle understeer—about credible when attempting to power out of a corner—is ever and then slightly more than pronounced hither than with the Nokians. Despite these pocket-sized complaints, noticeable generally in this controlled comparison setting, the XI3 remains a very well-balanced tire on snow and ice.
The XI3 scored evenly with the Nokian in three objective tests: snow dispatch, snow braking, and ice braking, while taking a 1-point hit on ice dispatch. In terms of objective results, the outset- and second-place tires are essentially the same.

This tire is a bit of a nighttime horse. Republic of finland's Nokian, the 19th-largest tire manufacturer in the globe, is probably unknown to many readers. Bridgestone is No. 1. Dunlop, Continental, and Yokohama are household names, and Michelin is a operation-tire behemoth. While it makes summer tires, Nokian specializes in wintertime-tire manufacturing, and it shows.
All the development, ongoing since Nokian introduced the kickoff dedicated winter tire 81 years ago, translates into a tire that outperformed or tied its competitors in every test, objective or subjective. In some cases, the margin of victory was narrow, every bit in ice dispatch, where it bettered the XI3 past a mere 0.17 second. But a win is a win.
The most middle-opening trait of this Hakkapeliitta R2 is the mode it steers on the snow and recovers from understeer. As steering bending increases, the R2 continues to plough the car where the other tires give up. Get into the push, dial it dorsum a few degrees, and the grip returns. It feels more than similar a summer tire in the moisture than a winter tire in the snow. And maxim Hakkapeliitta out loud is near as enjoyable as driving them.
The 1 category this tire didn't win is toll. In this size, the R2 costs $48 more than per tire than the second-place Michelin. That's a bitter pill when you are talking well-nigh something about drivers consider a winter luxury. Only we don't. If the best wintertime traction is what you want, and you tin can afford the premium, look no further.
