Winter is tough, especially on your car's tires. Did you know that cold weather can lower tire pressure? This article will show how to keep tires in top shape during Manitoba winters.
Stay safe and read on!

Key Takeaways
Cold weather makes tire air compress, which lowers pressure. For every 10 degrees Celsius drop in temperature, tire pressure goes down by about 1 PSI.
Keeping the right tire pressure helps avoid accidents and saves fuel. Underinflated tires can make cars harder to control and wear out faster.
Check your tire pressure often with a reliable gauge to keep them between 30 to 35 psi during Manitoba winters for safety and better vehicle performance.
Winter tires offer better grip and control in cold weather than all-season tires or summer tires. They stay soft below freezing, improving traction on icy roads. Studded tires are often used in Manitoba during the winter season as well.
Prepare for winter driving by installing winter tires, checking the vehicle's fluids, keeping an emergency kit in your car, and using tools like a digital gauge or portable air compressor for maintaining tire pressure.
The Impact of Cold Weather on Tire Pressure
Cold weather makes air in tires compress, leading to lower tire pressure. Drivers might see a noticeable drop in PSI during Manitoba's winter months.
Physics of Air Compression in Cold Temperatures
Air inside tires gets smaller when it's cold outside. This makes the tire pressure go down. For every 10 degrees Celsius drop in temperature, tire pressure goes down by about 7 kPa (1 PSI).
It's like how a balloon shrinks if you take it from a warm room to the cold outdoors.
At Dunn Chrysler Dodge Jeep RAM in Portage La Prairie, we understand how Manitoba winters can affect your vehicle. Keeping an eye on tire pressure during cold months ensures both safety and performance, says Melissa Draycott, our Marketing Manager.
Typical PSI Loss in Winter Conditions
In Manitoba's cold weather, every 10°F drop can lower tire pressure by 1-2 psi. This means tires may lose more air than usual during winter. Check your owners manual or vehicle information to confirm what your tire pressure should be.
So, checking tire pressure is crucial when temperatures fall. At Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, we find that keeping an eye on this can prevent many issues.
Cold air makes the air inside tires denser, leading to a significant psi loss. For drivers in Brandon, Winnipeg or any part of Manitoba really, staying ahead of this change ensures your vehicle performs well on icy roads.
We suggest monitoring your tires' psi frequently as winter sets in to maintain optimal safety and fuel efficiency.

Why Maintaining Proper Tire Pressure is Essential
Maintaining the right tire pressure is key to keeping you safe on the road and making your car run better. It helps avoid accidents, saves fuel, and reduces wear on your tires.
Safety Concerns with Underinflated Tires
Driving with underinflated tires puts you at risk on snowy Manitoba roads. Tires that don't have enough air can't grip the road well. This makes your car hard to control, especially when braking or turning.
In winter, this danger grows because icy roads need every bit of traction they can get.
Underinflated tires also make it hard for your car to move smoothly. This means it uses more fuel and wears out the engine faster. At Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, we see how proper tire pressure keeps you safe and saves money on gas over time.
Plus, tires that are not pumped up right wear out unevenly, leading to early replacements.
Keep your tires properly inflated for a safer drive and better fuel efficiency.
Impact on Vehicle Performance and Fuel Efficiency
Underinflated tires make your car work harder. This is because they have more rolling resistance, which means your engine uses more fuel to keep the car moving. Think of it like trying to walk in sand; it takes more effort than walking on a hard surface.
For customers at Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, ensuring tires are properly inflated is key to getting the best fuel efficiency. A small drop in tire pressure can lead to bigger fuel costs over time.
Cold weather affects how well your tires grip the road. When rubber gets cold, it stiffens and doesn't hug the road as tightly. This could mean your vehicle doesn't handle as well and uses more gas or diesel than necessary.
At Dunn Chrysler Dodge Jeep RAM, we recommend checking tire pressure regularly during winter months here in Manitoba—this simple step can help maintain optimal performance and fuel economy for every drive you take through Morden, Dauphin, or any other part of our beautiful province.
Increased Tire Wear and Tear
Tires lose air in cold weather. This makes them wear out faster. If tires do not have enough air, the edges wear down quickly. It's important to keep them at the right pressure for longer life.
At Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, we check your tire pressure during service visits. We help you avoid extra tire wear from Manitoba's cold winters. Keeping your tires properly inflated saves you money on new tires and keeps your car running well.

How to Monitor and Maintain Tire Pressure in Cold Weather
Checking tire pressure in cold weather is a must—air contracts with the drop in temperature, meaning your tires might lose pressure more easily. At Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, Manitoba, we recommend using a reliable tire gauge and ensuring your tires meet the recommended PSI for winter conditions.
Checking Tire Pressure Regularly
Keep an eye on your tire pressure every month. This simple check can save you from trouble down the road. Use a reliable tire pressure gauge to make sure your tires are at the ideal pressure for cold weather in Manitoba.
At Dunn Chrysler Dodge Jeep RAM in Portage La Prairie, we always stress the importance of this regular upkeep to all our clients.
Regular tire checks keep you safe and your car running smoothly, says Melissa Draycott from Dunn Chrysler Dodge Jeep RAM. We have all the tools and advice at our service drive-thru to help you maintain optimal tire pressure throughout winter.
Using the Correct PSI for Winter Conditions
In Manitoba, where winter hits hard, the right tire pressure is key. Cold drops tire PSI by 1-2 for every 10°C temperature fall. This means your car tires need a check-up more often in winter—every two weeks at least.
At Dunn Chrysler Dodge Jeep RAM, we recommend setting your tires to the correct PSI noted on your vehicle's door side or manual. It’s not just about numbers; proper PSI ensures better grip and fuel efficiency while driving through snow in Portage la Prairie.
Tools like a digital tire gauge help keep an eye on pressure levels. Our team can show you how to use them effectively or do it for you during service visits. Having the right tire inflation enhances safety and performance on snow-covered roads or icy conditions.
That’s why checking tire pressure becomes part of your routine in cold months—ensuring you stay safe as temperatures dip across Winkler, Elie, Neepawa, and beyond.
Tools and Equipment for Tire Pressure Maintenance
Keeping your tires properly inflated is key, especially in cold Manitoba winters. At Dunn Chrysler Dodge Jeep RAM in Portage la Prairie, we understand how crucial this is for your safety and your vehicle's performance. Here's a list of tools and equipment you should have:
Tire pressure gauge – It's small but mighty. Use it to check if your tires need more air. Do this once a month.
Portable air compressor – They come in handy when you find a tire low on pressure. You can use it right at home or keep it in your trunk.

Winter Tire Considerations for Manitoba Drivers
Choosing the right winter tires is crucial for Manitoba drivers, offering enhanced safety and performance in cold conditions. Keep reading to find out how switching tires can transform your winter driving experience.
Benefits of Winter Tires in Cold Climates
Winter tires are a game-changer in colder weather, especially for Manitoba drivers. They have a special rubber compound that stays soft even when temperatures drop below freezing. This means they grip the road better than all-season tires or summer tires.
In icy surfaces and snowy conditions, winter tires can cut down stopping distances by 30-40%. That's not just safer; it's potentially life-saving.
Narrower winter tires also play a crucial role. They improve your car's grip and lower the risk of hydroplaning when roads are wet or slushy. For anyone considering financing or leasing a car in Winnipeg or Portage la Prairie, adding a winter tire package from Dunn Chrysler Dodge Jeep RAM is smart planning for winter driving safety and performance.
Differences Between All-Season and Winter Tires
All-season tires and winter tires are not the same. All-season tires work fine in general conditions, but they don't match up to winter tires in cold weather. Winter tires have a special symbol – a mountain with a snowflake.
This shows they meet specific standards for snow performance. They can stop your car up to 40% shorter than all-season tires when it's cold and snowy.
Winter tires stay soft and grip better as temperatures drop, thanks to their tread compounds designed for cold weather. This is key for safe driving around Manitoba, where winters are tough. Studded tires are also a choice made by many Manitoba driver's.
Meanwhile, all-season tires tend to harden as it gets colder, which means less grip on the road. So, switching to winter tires makes driving safer and easier during those long Manitoba winters at Dunn Chrysler Dodge Jeep RAM in Portage La Prairie.
When to Switch to Winter Tires
Switching to winter tires is essential for secure driving in Manitoba. As temperatures drop below 7°C for five consecutive days typically around the end of October, it's time to implement the switch.
At Dunn Chrysler Dodge Jeep RAM in Portage La Prairie, we are well aware of this necessity. Our team suggests preparing your vehicle with winter tires before the cold is in full swing, but you can add winter tires through-out the cold months in our service department.
Given Manitoba's climate, using winter tires isn't just a wise decision; it's a move for safer and more proficient driving through snow and ice. As opposed to all-season tires, winter ones offer superior grip and control during cold conditions.
They contribute to assuring your safety on the road throughout our severe winters. Bear in mind, while Manitoba law doesn't mandate them, they're highly suggested for handling our seasonal difficulties efficiently.

Practical Tips for Manitoba Drivers During Winter
Tread depth is crucial for safe winter driving. Worn-out treads can lead to decreased traction on slippery roads, making it harder to control your vehicle and increasing the risk of accidents. Ensure your treads are in good shape before the onset of winter.
Finally, consider investing in winter tires. These tires are specifically crafted for cold weather, providing better traction and handling. While all-season tires can suffice in mild winters, they may fail to deliver in severe snow or ice conditions.
By taking these preventive steps, you can ensure a safer winter driving experience and prolong the life of your vehicle and tires. Drive safe and avoid going out in dangerous driving conditions!
Preparing Your Vehicle for Winter Driving
Getting your vehicle ready for winter driving is crucial, especially in Manitoba. At Dunn Chrysler Dodge Jeep RAM, we always remind our customers about the importance of installing winter tires.
