Whether you're new to driving in winter weather or a veteran in need of a reminder, we've taken the time to answer your winter tire frequently asked questions. Read below to find out the answers to common winter tire questions.

Why do I need winter tires?

All the four-wheel or all-wheel drive in the world won't help your vehicle stop any faster on snow and ice, and the features may actually be detrimental because of their tendency to make drivers feel invincible. Winter tires feature special rubber compounds and tread patterns that help them maintain traction and performance when temperatures dip and the weather turns.

Many vehicles leave the factory with all-season tires, which work well in a huge variety of conditions, temperatures, and weather. They don't, however, do as well in freezing temperatures and snowy conditions.

What's the difference between all-season and winter tires?

The rubber compounds in all-season tires tend to harden in cold weather, which can lead them to crack and fail to provide solid traction. Winter tires are made with special compounds that remain pliable in cold weather to provide the best traction possible. They also have deep tread cuts, which allow for better grip in snow and slush. According to Tire Rack, winter tires provide about 21 percent more grip than all-seasons in similar conditions.

Instead of all four, can I buy just two winter tires?

Owners of front- or rear-wheel drive vehicles may feel tempted to buy winter tires only for the two wheels that are being driven by the engine, but that's a mistake. While it may help with acceleration in snow and bad weather, installing only two winter tires can lead to instability and loss of control, because the two wheels without winter tires will have far less traction. If you're considering buying winter tires, wait until you can buy all four.

Do I need snow tires if I have all-wheel drive? Snow mode?

All-wheel drive is all about traction control. If your vehicle is equipped with tires that don't offer enough traction to get a grip on the road surface, it doesn't matter what the AWD system (or drive modes) get up to. You'll be slipping and sliding wishing for snow tires when the first few inches of snow get packed onto the roadway.

Can I drive on winter tires in the summer?

That depends. Some parts of the country that receive regular winter snow have limitations on the types of tires that can be used in warmer months. Many areas bad the use of studded winter tires outside of cold weather, due to the studs' tendency to damage roads and reduce traction when there's no snow on the ground. Beyond that, standard winter tires don't provide the same level of wet traction and grip that all-season or summer tires do, and they can wear more quickly because of their rubber compounds.

Can I use the same winter tires next year?

If you rotate between summer/all-season and winter tires, you should be able to get a few years out of your winter tires. As they wear, like other tires, they'll offer less grip and the rubber compound will become less flexible.

Nuts & Bolts


The MBUX Hyperscreen is a leap forward in infotainment and driver's information display design for the company's next-gen electric automobiles.

Mercedes-Benz has been lauded for the two screens, one housing approach to infotainment and driver's information in their latest vehicles. Then along came Cadillac's immense 37-inch three-screen approach to data and entertainment in the 2021 Cadillac Escalade. Mercedes is upping the game with its new MBUX Hyperscreen, which will debut in the EQS all-electric sedan.

The MBUX (Mercedes-Benz User Experience) was unveiled inn the 2018 A-Class and there are now more than 1.8 million Mercedes passenger cars with the equipment on the road worldwide. A second generation of the system debuted a few months ago alongside the new S-Class sedan. It's set to take another leap forward when the EQS makes the Hyperscreen available to buyers.

Here's what we know.

The screen is huge.

You can tell by the images of it that the screen is big. How big is it? The large, curved screen panel extends almost the entire width of the interior, from one A-pillar to the other. It measures over 56 inches wide and has 377 square inches of surface area. There is no vehicle on the market today with a similarly sized screen.

The screen incorporates digital and analog parts. There is a large digital surface that has traditional air vents integrated into the face. The Hyperscreen is surrounded by a continuous plastic front frame. The visible part of this frame is painted in a Silver Shadow color that has been applied in a three-coating process.

The large glass cover display of the Hyperscreen is curved in the molding process at a temperature of approximately 1,202 degrees Fahrenheit. The high-heat bending allows for a distortion-free view of the display unit across the entire width of the vehicle.

Ambient light has been installed on the lower part of the screen to give it the appearance of floating on the dashboard.

Mercedes has engineered the screen to have two coatings of the cover plate to reduce reflections and make cleaning easier. The screen is made a scratch-resistant aluminum silicate.

What happens to the screen in the event of an accident? Safety measures have been put in place as part of the engineering process. There are predetermined braking points alongside the side outlet openings as well as five holders that can "yield in a targeted manner in a crash thanks to their honeycomb structure" according to the automaker.

It's the brain and nervous system of the EQS.

In a recent statement, Sajjad Khan, Member of the Board of Management of Mercedes-Benz AG and CTO said, "The MBUX Hyperscreen is both the brain and nervous system of the car." He described it further, saying, "The MBUX Hyperscreen continually gets to know the customer better and delivers a tailored, personalized infotainment and operating offerings without the occupant needing to click or scroll anywhere."

Two parts of the display feature OLED technology.

OLED technology is used on the central and front passenger displays of the Hyperscreen. The technology allows for images that are self-luminous while unused space appears deep black. Active OLED pixels radiate with a high color brilliance, resulting in high contrast values.

All of the graphics on the Hyperscreen are styled in a new blue/orange color scheme.

It doesn't just look high tech. It is.

The Hyperscreen has a powerful computer system running it consisting of 8 CPU cores and 24 gigabytes of RAM. It has a 46.4 GB per second RAM memory bandwidth.

There are a total of 12 actuators beneath the touchscreen that deliver haptic feedback during operation. If the finger touches certain points there, they trigger a tangible vibration in the cover plate that a person can sense to know that their touch command has been received by the system.

The Hyperscreen is connected to a multifunction camera and a light sensor, which adapts the brightness of the screen to ambient conditions.

The MBUX system can hold the information for up to seven profiles and can be individualize for multiple front passengers.

Front passengers get their own screen and operating area.

As part of the design, front passengers have their own display and operating area. Entertainment functions of the passenger display area are only available in countries where it is allowed. If the passenger seat is not occupied, the screen becomes a "digital decorative part" where animated stars are displayed.

Crisp, clean graphics help make the screen easy to operate.

The MBUX Hyperscreen features most of the functions you'd find on a traditional center console in a fully digital format. Through research, Mercedes learned that most infotainment use cases fall into the Navigation, Radio/Media and Phone categories. Because of this, they put the navigation application at the center of the screen.

Many suggestions for the use of infotainment technology can be made by the artificial intelligence within the MBUX system, which monitors user behavior and analyzes it for patterns. For example, the system can issue a birthday reminder or suggest items from a to-do list.

Even further, if you always call one particular person on Thursdays on your way home from work, a business card may appear on the screen with their contact information instead of you having to find their contact info by scrolling through your phone, utilizing a voice command, or clicking through several layers of the screen's menus. Mercedes emphasize that these prompts can be dismissed with one button touch.

Zero-layer living is designed to make the Hyperscreen easier to live with.

With the Hyperscreen's zero-layer feature, users do not have to scroll through sub-menus or give voice commands to complete popular tasks. Mercedes has placed the most important applications in a "situational and contextual way" at the top of the driver's field of vision.

Stage 1, Jeddah to Bisha is entirely driven on tracks through valleys with rocks and stones that are a hazard for tires and windscreens. Several intersections also are considered hazardous.

The rally's Stage 2, Bisha to Wadi Al Dawasir, features yellow and white sand dunes with a lengthy off-track area near the end. Stage 3 is a pure desert stage in the gateway to the Empty Quarter where the route is in a loop that begins and ends in Wadi Al Dawasir. On this stage, speed racers will get their first real opportunity to cut loose.

The fourth day of competition is the longest. Stage 4, Wadi Al Dawasir to Riyadh, offers winding tracks while Stage 5 switches it up with a difficult section of dunes and stoney tracks as racers move from Riyadh to Buraydah.

Things get slightly easier for tires on Stage 6 where a variety of smooth sand dunes move the race along from Buraydah to Ha'il. Bikes will have their hardest day on this stage. There is a rest day between Stage 6 and Stage 7.

The terrain switches for Stage 7, moving to sand mountains and stony plateaus as the races move from Ha'il to Sakaka. There's over 100 kilometers of up and down racing.

Stage 8 crosses the northern part of the country moving west to east beginning at Sakaka to and heading on to Neom (shown above). It is another very long stage. This is the stage where competitors will likely have their cameras out.

The race features another loop stage for Stage 9, this time in Neom. The stage starts at the seafront but quickly turns difficult as soft sand fills in tracks preventing speed. Organizers say that this may be the most difficult stage of the entire rally.

Stage 10 moves the race south over hills and vistas from Neom to Al- 'Ula. The dunes return for Stage 11 as racers go from Al- 'Ula to Yanbu on terrain described by ASO as "an ocean of sand".

The final stage, Stage 12, features more dunes as the race returns to its start point in Jeddah.
