This year we took on comparison a premium and an average segment of tires of the most popular dimension - 185/65R15. Such tires approach, for example, on Kia Rio, Hyundai Solaris, and Lada Vesta.
I leave on the ice of a test tunnel. I begin to warm up brakes, and on a sound, I hear - wheels are blocked. Lada Vesta has to be equipped with ABS from the plant, is equal as a system of stabilization and anti-pro-slipping. For some reason, electronic assistants do not work! And it when every minute on the account. We have no spare Vesta, you would not learn what snow tires to take in dimensions 185/65 R15.
In comments to last year's material readers asked to compare Asian tires to the European. Therefore we added Yokohama iceGuard Stud IG55, Hankook Winter I'Pike RS and one more novelty of Bridgestone Blizzak Spike-02 to novelties of a season of Nokian Hakkapeliitta 9 and Nokian Nordman 7. The company to them was kept by the checked European models: Michelin X-Ice North 3, Pirelli Ice Zero and Gislaved Nord Frost 200.
Dispersal and braking on snow
This time at us the straight line was longer (800 m), than last year. It helped to obtain more data on each set, dispersing to 45 km/h and then urgently braking.
Result. A difference in braking it turned out small - worst of all Yokohama iceGuard Stud iG55 is slowed down, and it is better than all Michelin X-Ice North 3.
Resilience to drift on the snow road when dumping gas
Aspect, the second for importance, after breaking - the car resilience to drift in case of the driver's mistake: at sharp dumping of gas in turn on 75 km/h. It can occur if the person saw ahead danger or was frightened of a bend. It is the most widespread case of loss of control over the car in turn. It is higher than a point, the longer the tire resists a turn.
Result. The most predicted - Pirelli Ice Zero and Nokian Hakkapeliitta 9. The driver has time to take measures for prevention of a drift or a turn. And with Yokohama iceGuard Stud iG55 and Gislaved Nord Frost 200, it is necessary to be on the alert: easy dumping of gas and the car already goes in a drift, and the turn comes instantly and unexpectedly - the system of stabilization is necessary for such tires.
Stability and controllability on snow
At arrivals on the snow route, we watched at circle time as we a complex indicator of coupling, but also estimated behavior of the tire. Whether she forgives mistakes in the form of a locked of a wheel, too high speed on an entrance to turn.
Result. Pirelli Ice Zero showed the best time. However, in a limit bluff break a forward axis. Hakkapeliitta 9 forgive mistakes, and Nordman 7 nevertheless brings a back axis slightly more, than it is necessary for the ordinary driver. Bridgestone Spike-02, Hankook i'Pike RS and Gislaved 200 sharply break in demolition and adrift, demanding a filigree and mystery taxiing. From Yokohama iceGuard Stud iG55 you do not know what to expect: adrift, stability in the same turn at the same speed.
Passability in snow
This time we were lucky - a lot of snow dropped out. The depth of a cover made 19 cm! Such blockages meet at least one year in many Russian cities when entrances and departures to the yard are filled up. The clearance of Vesta allowed to carry out measurements on such deep snow and not to get stuck.
Result. Michelin X-Ice and Nordman 7, without straining, plowed a snow virgin soil. On Bridgestone and Hankook of Vest a few times got stuck, it was necessary to hand over back. Not too surely also Hakkapeliitta 9, with the most superficial protector (8,9 mm) rowed.
Dispersal and braking on ice
The thick snow layer on a roof of a test tunnel did not allow to use satellite Racelogic for measurements, it was necessary to pass to the optical Datron complex. Tests allow achieving indoors the reproduced results which do not influence wind, the sun, temperature drops.
Result. Worst of all brake Yokohama iG55, they lose to the majority of tires about 7 meters only from 25 km/h. Let's not bad result of Hankook Winter i'Pike RS - they stop on average 3 meters most further the others.
Cross-coupling on ice
In comparison with the previous year, the ice circle was added to traditional tests. The driver, gradually accelerating, goes on a circle with a diameter of 270 meters from the included ESP before its operation, thereby the human factor at measurements decreases, and to the forefront, there is a side coupling of tires on ice.
Result. New Hakkapeliitta 9 with two types of thorns (for cross and longitudinal coupling) went to another dimension. A difference in speed such that Nokian will catch up with Yokohama iceGuard IG55 through 5 circles! Not bad Pirelli and Michelin proved. Bridgestone Spike-02 showed weak cross-coupling with a slippery surface.
Stability on ice
The route with different turns helped to answer a question of complex coupling on the ice, and also it is now predicted for the ordinary driver the tire breaks in a drift. We noted the time of a circle and gave points for stability - the more the better.
Result. After Hakkapeliitta 9 it seems that other tires have no thorns, the difference in coupling on ice is so big. Let's note that, despite the worst time of a circle, more we predict Bridgestone, than Hankook, Gislaved, and Yokohama. To them, we lowered estimates for the fact that after failure in sliding stabilization, despite all actions of the driver, happens very long.
Braking on wet asphalt
In the winter in the cities wet asphalt - the typical phenomenon. On each set of tires, we dispersed to 93 km/h and urgently slowed down 6 attempts.
Result. For the first time for many generations of Hakkapeliitta, it appeared among leaders in a break way on wet asphalt. Well, also Gislaved Nord Frost 200 acted. Four meters worse on wet asphalt brake Yokohama - it is equivalent to a car length.
Stability on the wet road
We tested cross-coupling on the wet road on an artificially irrigated route. And, as in winter disciplines, especially watched closely the behavior of the car in turn - whether will be an unexpected drift.
Result. As well as on braking, the best time and safe controllability at Hakkapeliitta 9. Also well Gislaved acted. The tendency to drifts on wet asphalt was found in Yokohama iG55 and Bridgestone Spike-02.
Braking on dry asphalt
In million-plus cities, dry asphalt becomes in the winter a usual thing too. On each set, we brake from 93 km/h, and to offset there is a break away from 90 km/h to 5 to neutralize the reaction time of the brake system.
Result. The worst result - at Nordman 7. Also badly Hankook i'Pike RS and Bridgestone Spike-02 acted. And the shortest brake way was shown by Yokohama iG55 which failed all tests on snow, ice and wet asphalt.
Noisiness was estimated by an expert method (the higher than a point - it is more silent the tire). The rumble which is less in decibels can be perceived by the person as unpleasant, importunate. Measurements were carried out on asphalt. It is important to understand, the car class is higher, the less you will be disturbed by the noise of thorns. And in Vest loudly anyway.
Result. Gislaved and Hankook were the most silent. And the most - Pirelli. Nokian and Bridgestone rustle loudly too, but slightly less annoyingly.
The smoothness of the course
Smoothness was estimated on snow and asphalt roads on drivers and back passenger places.
Result. Hankook Winter i'Pike RS and Gislaved Nord Frost 200 in dimension 185/65R15 proved doubly: small roughnesses in detail transfer to the salon, and large will softly amortize. The most pleasant were Michelin X-Ice North 3 with a soft sidewall, and the most - Bridgestone Blizzak Spike-02 and Yokohama iG55.
Resilience to side cuts
Side breakdown usually is not subject to repair, the tire should be changed. And one tire, for safety reasons, not to manage. As well as last year, as an obstacle, we used whetstone 92 mm high. Every time began dispersal with the same place, and every time turned the tire that the blow had in a new zone. Noted not only final breakdown of the tire but also intermediate deteriorations in a state, since 40 km/h and with a step to 5 km/h. Unfortunately, the failed "carrier" Mercedes-Benz of a C-class did not allow to finish testing. Therefore we do not include the sidewalls given on durability in the final table and we give them for reference.
Result. Pirelli Ice Zero possesses the strongest sidewall, long resisted breakdown and Bridgestone. Nokian Nordman caught hernia on 45 and 50 km/h before dying on 55 km/h. Michelin kept to 55 km/h without hernias then there was a small cut without damage of a cord. At the first journey on the heaviest tire, Yokohama iG55 on 40 km/h did not sustain the lower level of a suspension bracket of the car.
The effort to a thorn
The efficiency of a snow tire directly depends on the number of thorns. Over time they drop out, coupling decreases. The effort to a thorn is higher, the better he sits in the tire. We armed with a dynamometer, nippers and began to tear out "nails": on average on 6 pieces from different places of a protector.
Result. After a couple of torn-out thorns at Bridgestone we did a break - the exhausting occupation. And here "nail" Gislaved and Nokian jumped out from the places easily.
Tires a premium and middle class in general well proved to be, losses of thorns was not noticed. Each model has the focus as a covering, therefore, read a short conclusion on each tire below. (We pay attention if in shop noticed a new symbol or a letter in the name of the tire, then it is another model with the advantages and shortcomings)
