Ground track length of 10.6 km consists of sections that simulate conditions of highways, local roads and dirt roads, making it possible to test tires at highway speeds, and speed of urban traffic.
In addition, there are areas of smooth and coarse concrete, as well as new asphalt coating after patching. This allows us to determine the level of noise, comfort, quality, speed and control in everyday life, because the conditions are identical to those faced during normal travel to work.
During the road test were considered the most comfortable tires Pirelli P Zero Nero All Season, since they effectively absorb road surface roughness on the sites with "patched" with asphalt. Followed immediately by Continental ExtremeContact DWS, which also allow the driver to feel more comfortable on rough roads.
Michelin Pilot Sport A / S Plus proved to be a little stiffer than the Pirelli and Continental, particularly at the junctions of asphalt surfaces on the highway. Regarding BFGoodrich g-Force Super Sport A / S, they provide a decent quality of the tires for this category, but the team testers recognized their most severe in this test.
At the same time tough course BFGoodrich g-Force Super Sport A / S was offset by a better sensitivity to steering and stable handling on the exit of the highway and in fast cornering.
P Zero Nero All Season and the Pilot Sport A / S Plus also showed good results, and the sensations were virtually identical. Especially worth noting their predictable response to driver - not too harsh or too inhibited.
ExtremeContact DWS also have good handling, but was spotted a small dead zone in direct motion on the highway, because of what has to constantly taxi up to the car continued to go strictly on a straight line.
P Zero Nero All Season steel in the test of the quietest tires, and was marked by a faint noise when driving on a variety of coverages. The same applies to the Pilot Sport A / S Plus, but Michelin tires yet published a noticeable noise at the junctions of asphalt pavements and on the cover with the "patched" with potholes.
According to the noise level close to them and ExtremeContact DWS, which became a little quieter than the previous model ContiExtremeContact. More Sport g-Force Super Sport A / S generate discernible noise at certain speeds, but this clearly discernible ringing sound when hit by an obstacle on an uneven surface.
Race Tracks
Test Track (the length of one lap - 0.5 km) includes a 90-degree rotation, motorway, as well as several bands, to determine how to behave in a bus during the rebuild.
Tires were tested and the dry and wet surfaces, so that the pilots were able to test the tires on the levels of grip, responsiveness, handling and driving performance, which in ordinary life are only needed during emergency maneuvers or racing competitions.
Sport g-Force Super Sport A / S, which they showed in the road test, it is useful BFGoodrich tires and the track of their fast response to steering and stability during cornering have allowed buses to show the best lap time.
Pirelli P Zero Nero All Season possess a relentless grip, allowing them to catch up with the g-Force Super Sport A / S in a test for lateral acceleration, but with Pirelli tires sooner than you might expect, include ABS during hard braking.
Pilot Sport A / S Plus differ predictability during maneuvers at high speed with barely a hint of understeer when reaching the limit of adhesion. ExtremeContact DWS has also been called balanced, but their response at the helm has been slower than uostalnyh test tires.
Test results on a dry racetrack
In a test on the wet surface, the results of tires in terms of predictability, the clutch and the overall balance significantly varied. Continental ExtremeContact DWS significantly vybilis forward and behaved as if the track is not had no water.
Tyres Continental chalked up the best time of the slalom, the highest lateral acceleration on a circular track skidpede - and the best lap time in this test. In particular were marked by high predictability and excellent handling, allowing the driver to feel more confident.
Second place was taken by Pirelli P Zero Nero All Season, which also have excellent handling, but the level of cohesion behind the Continental. Michelin Pilot Sport A / S Plus just a little lost Pirelli, as their stable handling several suffered because of weak coupling the front tires, which means understeer.
BFGoodrich g-Force Super Sport A / S, which were the sport on dry surfaces, could not keep this feeling in the wet - they just did not have enough traction to compete with other tires tested, in addition Also during the loss of adhesion, they are much more slowly regained contact with the road.
