Accordingly, improve vehicle stability and simplify the start and acceleration in the same conditions. But on dry and wet asphalt spikes on the contrary significantly reduce the grip, which in turn significantly lengthens the braking distance and reduces nanooptical, and in loose snow or swamp road spikes much mytree "vapout" Your car and put him "on the belly". In many European countries spikes are prohibited, as a phenomenon, and it's not only in the preservation of a road surface.
In addition, many modern studless winter tires for traction in open ice almost as good as the spikes, especially if the temperature drops below -15 degrees. This is due to the structure of the tread, which is "carved" transverse slats (popularly called "Velcro").
When thinking about the spikes, try to remember how many days last winter under Your wheels was a real ice? If You really often with bated breath to watch will stop if Your car before the next obstacle, feeling the vibration of the brake pedal (if you have the ABS system), You probably either need thorns, or else it would be worthwhile to review the style of winter driving. In addition, the spikes are more effective for heavy SUVs and can be useful to the owners of rear-wheel drive cars on slippery slopes.
In any case, you must bear in mind that the use of studs definitely should improve Your caution on the road in the winter and reduce the speed limit, because very often the behavior studded rubber on different surfaces totally unpredictable. Even the ice is not always uniform, and if Your vehicle is not equipped with modern systems alignment of tractive and braking effort at each wheel spikes can cause drift much faster than tires without studs.
