Andy and Mercedes Lilienthal , founders of theSubcompact CultureandCrankshaft Cultureblogs , grew up in the Midwest , a " darn - near arctic environment , " as Andy calls it , and never used snowfall tyre . But in 2003 , Andy bought a set of wheel that come with winter tires mounted on them . The first meter he drove in the snow with winter tires , he says , " I was amazed at how much good they were — traction , handling , braking , everything . "
But do n’t get wintertime tyre confused withstudded snow tires . Winter tire do n’t have the alloy stud protruding from the pace that can sometimes provide grip in frigid conditions . Instead , they ’re made of specialized galosh compounds with particular pace patterns that provide serious grip in more types of cold - weather condition condition .
What Makes Winter Tires Different?
The rubber used in wintertime tyre demand cold temperature to work at their full . According to Ron Margadonna , an engineer at Michelin Automotive Tires , that caoutchouc used gets to the very molecular essence of tire engine room . Most manufacturers also use silica in the compound for wintertime tires because it helps the caoutchouc stay elastic ( rather of hardening ) when temperatures cast off below freeze — or even below zero .
The pace pattern of winter tire , Margadonna says , feature inscrutable patterns so the tyre can get grip in snow . The pattern has more groove and cut in the tread , fuck as sipes . And the tread blocks in the design are smaller so there are more edge to prick into the snow and ice . " All of these are traction economic aid , " Margadonna says .
The channels in wintertime tires are often wider , and there are more of them than in all - season tires . More channels means even more boundary that can grip snowy street . Wider channels also means they can clear out snowfall and slush from the pace more quickly instead of becoming packed full , which reducestraction .
Who Needs Winter Tires?
If you stake pictures of yourself outdoors wear upon your one fond sweater on the one day a year that blow stir descend in your neighborhood , you believably do n’t need wintertime tires . All - season tireswill supply enough hold on mogul for you .
But if you inhabit in an area that sees regular snowfall or frigid conditions , then winter tyre will render the extra adhesive friction you ’ll take for daily driving . tyre manufacturers often summons 45 degree Fahrenheit ( 7 degrees Anders Celsius ) as a benchmark . If your winters are , on average , below that , then Charles Percy Snow tires will likely help . expert urge installing a full set of four wintertime tires to repress the chance of skidding when the weather turns .
wintertime tire are engineered for cold temperature , but it ’s not the end of the creation if you do n’t swap them out for all - season tire when weather warms . It is n’t necessarily peachy either , though . Because winter tires use a indulgent rubber compound than standard tire , running them every day on dry pavement will wear them out quicker , Margadonna says . And they do n’t provide optimal adhesive friction on warm , dry roads .
Of course , if you do habituate both winter and summer tire , you have to salt away the extra set when it ’s not in use . The Lilienthals merely store their sets of off - time of year tire for their four vehicles in a crawl space under their household .
Margadonna says a lot of people assume that if they have all - steering wheel drive orfour - wheel drive , they do n’t need winter tyre . " Those systems are only as serious as the tires on the fomite , " he warns . While sending power to all four wheels does increase a fomite ’s abilities in bad weather , it ’s the tires that give the car better starting traction , braking and cornering potentiality .
How to Tell If It’s a Winter Tire
severalise winter tyre from all - season tires is easy . Just look for the peck and flake icon on thesidewallof the tire — the part easily visible when you stand next to the tire — then it ’s a wintertime tire . " We call it the ' mountain peak and snowflake marking , ' " Margadonna says . That symbolization mean it ’s passed traction tests on snow carry by theU.S. Tire Manufacturers Association .
Just remember : Winter tire are not constellate tires . In fact , many state have banned constellate tires outright . Those little alloy stud poker deplume up paved route when there is n’t snow covering them . Margadonna points out that while studded tires can be slightly beneficial on methamphetamine hydrochloride , " they declare oneself no enhancement on coke . " And they are n’t eventhat greaton ice . The studs can grip diffused frosting , but when ice-skating rink becomes hard and brickly , they have less grip . Michelin does n’t even sell studded tires . " Studless tires can do what studded tires do and more , " Margadonna say .
Mercedes Lilienthal agrees . " Studded tires are not the best exercise , " she says , while admitting that the Lilienthals do have and sometimes use studded tires . In many parts of the country , the roads are n’t incessantly embrace with soft ice . There are many days when the roads are clean , and " studs are worse for braking in showery or wry conditions , " she says . " If you have to terminate in a pinch with studded tire on a teetotal route , you ’re in a world of hurt . "
