What Are Snow Tyres
Snow tires, also known as winter tires, are tires designed for use on snow and ice. Snow tires have a tread design with larger gaps than those on conventional tires, increasing traction on snow and ice. Such tires that have passed specific winter traction performance tests symbols on their sidewalls. Tires designed for winter conditions are optimized to drive at temperatures below 7 °C (45 °F). Studded tires are a type of snow tires which have metal or ceramic studs that protrude from the tire to increase traction on hard-packed snow or ice. Studs abrade dry pavement, causing dust and creating wear in the wheel path.
Improved grip
When you're driving through ice and snow, the improved grip of snow tyres is big advantage. The tread patterns are specially designed to grip the snow and ice, and feature large tread blocks and deep grooves that cut through the snow. It throws the snow back and keeps the snow from getting packed down in the tread, which happens with all-season tire tread patterns.
Better braking
Most of us know that scary feeling when you brake in the snow and ice and your vehicle just keeps sliding through the stop. With snow tires, the sturdy grip helps you break when you need to.
Longer life for regular tires
When you switch out your regular, all-season tires for snow tyres, you're giving them a longer life by not riding on them all year round. While you might have to pay for two sets of tires, in the long run you'll be saving money.
Whether your vehicle is front or rear-wheel drive, winter tires are best applied to all wheel positions. While some drivers question the necessity of changing all four, there are good reasons why tire and vehicle makers recommend using a full set of winter tires.
For one thing, just mounting two means you lose some of the traction, stopping and cornering advantages a full set provides. No matter what kind of vehicle you drive, never mount two winter tires on the front axle without also mounting them on the rear axle. Only installing snow tires on the front wheels increases the risk of losing rear tire traction while braking or cornering on wintery roads. This is because the back wheels will have less grip than the front wheels, a scenario that can throw you into a rear-wheel skid.
But what about just mounting winter tires on the back wheels, especially if your vehicle is rear-wheel drive, shouldn't that be enough?Remember that in a rear-wheel drive vehicle, the front wheels steer and the rear wheels provide the power. So if your rear tires can grip the road but the front tires can't, any effort to steer the vehicle in the direction you want to go on wintery roads will be more difficult.
The Different Types of Snow Tyres
Studded tires
One of the best snow tyres are studded tires. These tires, as their name suggests, have tiny metal studs inserted to the tread. The studs improve handling and performance on the ground by helping to grip ice and snow. The metal studs provide extra traction by digging into the snow and ice, keeping the tires firmly in touch with the surface. They are strong but lightweight. Stubby tires are the best choice for slope driving in the winter since they provide superior handling, more stability, and surface contact.
Non-studded snow tyres
These are also frequently referred to as studless tires or winter tires. These tires don't have any studs embedded in the tread, in contrast to studded tires. They have a three-peak mountain deterioration with a snowflake sign on the sidewall, making them immediately recognizable. Their tread pattern and the winter compound they utilize give them the traction needed in wintery conditions. Their aggressive and intricate tread patterns increase traction and grip. The winter compound increases rubber's elasticity in chilly conditions. The winter rubber compound used in non-studded tires is the main factor enhancing their performance. The tire's ability to flex under harsh weather circumstances is made simple by the compound's ability to remain soft even in extremely high temperatures.
Studdable winter tires
Studdable tires provide the newest technology if that is what you are looking for. This hybrid option is offered by these winter tires. Offering excellent grip in winter situations by combining the finest qualities of studded and non-studded tires. Although studdable tires can have studs, they are not sent with them already attached. They have tiny holes already drilled into the treads so that studs can be added and removed as needed. These tires have gained popularity in the majority of states due to the restrictions and regulations placed on studded tires. Tires with studs provide excellent handling and stability on a variety of winter surfaces. They have been built to withstand extremely harsh winter conditions, and they also guarantee good grip when driving on slush, ice, and snow.
The question of when to change over to snow tyres is very much location-dependent. Some locales experience an earlier start to winter than others. When you check the long-term weather forecast and begin to see temperatures consistently around or below 40° fahrenheit, and/or the chance for wintry precipitation, it's time to change to snow tyres.
For example, in the midwest, a change to snow tyres often occurs around mid-november, and then depending upon how long old man winter hangs around, swapping out snow tyres in mid-march. In certain mountain regions and at higher altitudes, winter storms can hit as early as october and as late as april or may. So the timing of the snow tire exchange has everything to do with your local forecast and travel plans.
A bit of friendly advice from those with ample (maybe too much) tire shop experience: You'll have better luck beating the crowds before the real winter weather hits, and drivers learn their tires are no longer fit for duty. When snow tyres are dismounted, be sure to store your tires properly for maximum tire life.
Is your car free of ice and snow? You can finally move off. However, the major pitfalls now await. Whether steering or braking, particular care is required on icy roads. Discover the three most important tips for driving safely in winter.
Drive gently, evenly and smoothly
Whether you're driving on ice, in snow or just in cold weather, winter weather makes the car react totally differently compared to summer conditions. It is more likely to skid and the braking distance also becomes longer. You must adjust your driving style accordingly. The fundamental principle: Always drive gently, evenly and smoothly and keep the speed down. Traffic lights and crossroads present particular hazards. Even light braking can be hazardous if there is not enough clearance for the car in front. Always maintain sufficient distance. A sound rule of thumb is: Three times the distance required for dry roads. Also remember that other drivers may be less cautious than you.
Move off carefully
Trying to move off in the snow but the car won't move? Roads provide less traction in winter. The tyres keep spinning and dig even deeper into the snow. It is easier to make progress when driving in a lower gear. The power transmission is gentler and more effective. The result: Tyres have better grip and can handle the ground conditions better. It is therefore recommended that you drive in second gear in icy conditions. When changing gear, press and release the clutch slowly.
Pay attention to steering and braking behaviour
Do not only adjust your speed. Steering behaviour is different on snow and ice compared to in summer conditions. As an example, the car may quickly swerve on a bend. In this case: Release the clutch and do so quickly, but counter-steer sensitively. If the vehicle does not react to steering, then an emergency stop is the only remaining option.
As the winter season arrives, it's important to ensure that your vehicle is equipped with proper snow tyres for safe driving in snow and icy conditions. Check the tire pressure regularly
Cold weather can cause the pressure to drop, so it's important to keep your tire pressure at the recommended level. Proper tire pressure ensures better fuel efficiency and prevents accidents.
Rotate your tires
Regularly rotating your tires ensures that they wear evenly, which contributes to better traction on the road.
Clean your tires
Snow and salt can cause corrosion and damage to your tires. Clean your tires regularly with warm soapy water and dry them completely before storing your car.
Store your snow tyres properly
When switching to all-season or summer tires, store your snow tyres in a cool, dry, and dark place. Avoid exposure to direct sunlight or extreme temperatures.
Replace your tires when needed
Worn-out tires can be dangerous in winter weather conditions. Check your tires for signs of wear and replace them if needed.
Taking care of your snow tyres ensures safe driving and prolongs their lifespan. Don't neglect this important aspect of winter driving, and enjoy a safer and smoother journey.
Keep in mind, not all snow tyres are the same. The first is tread design, which for snow tyres will often be directional or asymmetrical. In order to lessen the possibility of hydroplaning on slippery roads, directional tread patterns, which have a v-shaped tread pattern, do a great job of funneling water, slush, and melting snow out of the tire. The purpose of an asymmetrical tread pattern, which contains two tread blocks that match and one that doesn't, is to improve handling on slippery, icy, slushy, and snowy surfaces.
Tread patterns are significant for wear and tire rotation in addition to performance characteristics. Asymmetrical tires can be freely rotated as long as the side marked outside is facing out, unlike directional tires, which must be turned from rear to front or from front to back. Snow tyres are commonly classified into three categories independent of tread patterns: Studded, studdable, and studless. A technician will insert a small piece of metal or ceramic material called a stud into the tire to improve traction in extremely slippery conditions such as ice, snow, and slush.
Make sure they are the appropriate size first. The set of numbers can be found on the sidewall of your current tires, immediately next to the rim, or in the owner's manual for your car. Utilize a tire tread depth gauge to secondly measure the tread depth. Alternatively, have a tire shop technician fix it; it ought to be free. Each tire's grooves should have measurements taken several times.
The tread depth of a fresh tire is usually 11/32nds of an inch. A winter tire's performance on snow is set to decline significantly if there is only 6/32nds of an inch or less of tread left on it. Be certain that there is no issue with uneven wear. Did your measurements from the tread gauge reveal any variations in tread depth between the four tires? Tires frequently wear in different ways over time. Installing snow tyres only on the front or back of a vehicle is likewise a bad idea. This significantly alters the amount of traction between your axles. This will result in less steering control rather than more.
