Testing All Terrain Off-Road Tires
BFGoodrich All Terrain: With Worms
BFGoodrich is a Best All Terrain Tires that has literally become a benchmark in the segment and a marker of "understanding jeep". The model is characterized by a characteristic tread pattern with “worms” . A special step of arrangement of tread blocks with self-locking elements stabilizes the central part of the tread and prevents it from “walking”. The technology of the structure of the blocks of the shoulder zone of ShoulderLock, when the inter-block grooves expand from the base to the working surface of the tread, provides excellent grip in off-road conditions .
Add here the two-layer composition of the rubber compound, which is made stiffer at the base, the high-strength construction of the TriGard carcass with a triple layer of polyester, two wide layers of steel belt, a protective ring and a reinforced sidewall construction - and it will become clear why this tire is one of the market leaders .
Yokohama Geolandar A / TS G012: all-season, but not for the Arctic
At one time, the Russian division of Yokohama did not even spend on advertising this tire - it already flew off. This is one of the most impressive looking models in the A / T segment: an aggressive stepped tread design with the name DAN-DAN puffs out underlined by large blocks and promises confident driving on any road. A powerful central rib stands out, as if laid out from large oblong tiles. The use of five-step tread technology has reduced resonance and minimized noise. Rubber is notable for good self-cleaning when it comes to ordinary dirt, but in heavy clay the tread tends to “get washed out” . Doesn't like mix and low temperatures so it’s better not to use it as an all-weather season for cold areas.
Goodyear Wrangler AT / R: reliable grip, but ...
A charismatic tire with an aggressive pattern laid out of triangular blocks is designed for movement on city roads and country roads. Omnidirectional tread blocks with radial and longitudinal blades are ready to catch on any roughness on the road , additional grip due to numerous edges. This provides a reliable grip of the tire with any type of road surface.
Although the manufacturer claims that the special design of the blocks of the shoulder area of the tread reduces the level of external noise, but, according to customers, the tire behaves more softly on the ground, and on the asphalt it just makes a lot of noise . The silicon-containing composition of the rubber compound with a special polymer makes the mixture flexible enough to cling well to both dry and wet surfaces, and a reinforced frame made of modern heavy-duty materials allows you to not be afraid of cobblestones and bumps. Noteworthy is the developed negative tire profile, that is, a system of grooves and channels that effectively removes moisture and dirt from the contact patch.
TOP 5 cars with the best brakes
A curious study was carried out by European car experts who tested nearly 60 cars in the discipline “most effective braking”. Portal "AutoVzglyad" will talk about copies that are in the top ten.
For several days, our colleagues at Auto Motor und Sport tested cars for the best braking performance. There were two people in each of the cars, and the tests were carried out after heating the brake system - the control tenth measurement was preceded by nine sharp depressions of the brake pedal to the floor at a speed of 100 km / h.
Of course, the intensity of vehicle deceleration depends not only on the main cylinders, disks and calipers, but also on the mass of the car, its aerodynamic characteristics and tires.
LEXUS
From 100 to 0 km / h, the “hot” Lexus LFA with a 560-horsepower V10 under the hood, with emergency deceleration, travels a distance of 31.6 meters. Not least due to the fact that the car is not equipped with the Japanese, but the Italian Brembo brake system - 390 mm carbon-ceramic discs in the front and 360 mm at the rear, monoblock calipers with six and four pistons.
MERCEDES-BENZ
A similar distance from 100 km / h during aggressive braking overcomes Mercedes-AMG GT S . In its arsenal is a 510-horsepower V8, as well as Brembo 420 mm carbon-ceramic discs in front and a diameter of 360 mm at the rear. It should be added that the "German" is heavier than the "Japanese", and therefore is experiencing the greatest load - hence the higher position than the Lexus in the TOP-10.
PORSCHE
A handsome Porsche 918 Spyder with a fiery heart about 887 forces is required to a complete stop of 31.4 meters. It is worth saying thanks to the carbon-ceramic with a diagonal of 410 mm in front in combination with 6-piston fixed calipers and 390 mm with 4-piston - at the rear. And again Brembo.
PREFABRICATED SOLYANKA
A little faster brake KTM X-Bow GT with a motor about 340 "horses" and a Ferrari F12 Berlinetta with a powerful 740-horsepower unit. The braking distance of these "lighters" is 31.3 meters from 100 to 0 km / h. Lotus Exige Cup 380 and Chevrolet Corvette C6 Z06 stop three tenths of a meter earlier.
CHEVROLET
In third place is the burning Corvette C7 Grand Sport with an indicator of 31 meters, which turned out to be heavier than its rivals, who achieved a similar result. The car, driven by 466 "stallions", is equipped with aluminum monoblock calipers with pistons of the so-called differentiated diameter. Here is lightweight carbon-ceramic disks.
