winter tire season is coming

why do i need winter tires?

Winter tires are specifically designed to provide better traction and handling in cold weather, snow, and icy conditions. They have a different rubber compound and tread pattern that perform well in low temperatures. This helps reduce the risk of accidents and improves overall road safety during the winter months. Winter tires offer better grip on slippery surfaces, which is crucial for maintaining control of your vehicle in snowy and icy conditions. They can reduce the likelihood of skidding and accidents, and they can significantly reduce your vehicle's stopping distance on icy or snow-covered roads. This is crucial for avoiding collisions, especially in emergency situations.

Using winter tires during the cold season can extend the life of your all-season or summer tires. This means you won't have to replace your regular tires as often, which can save you money in the long run. Knowing that you have the appropriate tires for winter conditions can provide peace of mind. You'll feel more confident and secure when driving in challenging weather, reducing stress and anxiety associated with winter driving.

In Ontario, it's a legal requirement to have winter tires on your vehicle during the winter season. The province mandates the use of winter tires from December 1st to March 31st on certain types of roads, including most highways. Some insurance companies in Ontario offer discounts to policyholders who use winter tires. This is because winter tires can reduce the risk of accidents, which ultimately saves the insurance company money. If you're involved in an accident during the winter season in Ontario and you don't have winter tires on your vehicle when they are legally required, you may be held legally liable. This could result in fines and increased insurance premiums.

Once the daily average temperature consistently falls below 7°C (45°F), it's a good time to consider switching to winter tires. This is because winter tires are designed to provide better traction and handling in colder conditions. Tire manufacturers usually put out their rebates on the 1st and 15th of October.

Did you know that many cars have a newer a/c system and refrigerant? We are able to service, fill and charge both. So, what's the difference, and why did it change??

R134a (the old one) and R1234yf (the newest system) are both types of refrigerants used in air conditioning systems, but they have some significant differences. Here are the key distinctions: 

R134a is a hydrofluorocarbon (HFC) refrigerant with the chemical formula CH2FCF3, while R1234yf is a hydrofluoroolefin (HFO) refrigerant with the chemical formula CH2=CFCF3. The chemical structures of the two refrigerants vary, resulting in different properties. 

Global Warming Potential (GWP) is a measure of how much a substance contributes to global warming over a given period. R134a has a GWP of 1,430, which is relatively high compared to other refrigerants. On the other hand, R1234yf has a significantly lower GWP of 1, which means it has a negligible impact on global warming. 

Due to its high GWP, R134a is considered a greenhouse gas and contributes to climate change. In contrast, R1234yf has a minimal environmental impact, making it a more environmentally friendly choice. 

R134a has been widely used in automotive air conditioning systems for many years. However, due to its high GWP, it is being phased out in many regions to comply with environmental regulations. R1234yf has been introduced as a replacement in new vehicle models to meet the more stringent environmental standards. 

R134a and R1234yf have similar cooling capacities and energy efficiency. However, R1234yf generally requires different system components and lubricants due to its different chemical properties. It is important to note that retrofitting an existing R134a system to use R1234yf may require modifications and can be more complex. 

Both refrigerants are classified as mildly flammable, but R1234yf has a lower flammability rating compared to R134a. This difference in flammability has led to additional safety measures and design considerations for systems using R1234yf.




Proper maintenance ensures that your vehicle is in good working condition, reducing the risk of accidents or breakdowns. Regularly checking and maintaining essential components like brakes, tires, suspension, and lights helps ensure your car is safe to drive.  Regular maintenance helps identify potential issues before they become major problems. By performing routine inspections and servicing, you can address minor repairs or adjustments early on, preventing larger and costlier breakdowns later. This helps improve the overall reliability of your car and reduces the chances of unexpected failures. A well-maintained car tends to have a longer lifespan. Regularly changing the engine oil, replacing filters, checking and topping up fluids, and following the manufacturer's recommended maintenance schedule helps keep the engine and other vital components in good condition. This can extend the life of your vehicle and save you money in the long run.  Routine maintenance, such as checking and replacing air filters, spark plugs, and fuel filters, can significantly improve your car's performance and fuel efficiency. Neglecting these maintenance tasks can lead to reduced engine power, decreased fuel economy, and overall poor performance.  If your vehicle is under warranty, following the manufacturer's recommended maintenance schedule is usually a requirement to maintain the warranty coverage. Neglecting regular maintenance can void your warranty, leaving you responsible for repair costs that would have otherwise been covered.  If you plan to sell or trade-in your car in the future, a well-maintained vehicle will have a higher resale value. Potential buyers are more likely to pay a premium for a car with a documented maintenance history, as it provides reassurance about the vehicle's condition and reliability.

Regular car maintenance is essential for safety, reliability, longevity, performance, fuel efficiency, warranty compliance, and preserving the resale value of your vehicle. By investing time and effort into maintaining your car, you can enjoy a smoother and more cost-effective ownership experience.  Let J.M Automotive help you to get the most out of your vehicle so that you can enjoy your vehicle for years to come.
