Tire Compounds

All-Season vs All-Weather vs All-Terrain

At Johnston Motor Sales, we understand how difficult it can be to make the right choice for your tires. With all the different tire options today, it is difficult to understand which is the right tire for you. Below is a breakdown of each tire compound and how each one can benefit you and your driving habits.


All-Season tires perform very well in three out of the four seasons. These tires excel in both dry and wet conditions when the ambient temperature is greater than 7°C. This is because the rubber compound is able to stay flexible and is able to make complete contact with the road surface. The more contact the tire is able to make with the ground, the more traction the tire will have. If you see the image below, Tire A is underinflated and Tire B is overinflated. Both of these conditions cause the tire to make less contact with the road resulting in far less traction than Tire C, which is making full contact with the road.

When the temperature drops below 7°C the rubber stiffens becoming less flexible resulting in a contact patch like Tire A & B. This may result in tire spin when accelerating and skidding under braking conditions. When there is a combination of both snow and low temperatures these conditions are amplified even more. In addition, All-Season tires tend to have a tighter tread pattern which makes it harder for the tire to evacuate the snow from the tread as it drives. When a tire cannot evacuate the snow, there is less contact to the ground similar to Tire A in the diagram above. While there are some All-Season tires that can perform well in winter conditions, the safest practice is to have winter tires for the winter months.

All-Weather is a hybrid of All-Season and Winter tires that can give the best of both worlds when it comes to traction in all four seasons. These tires are not designed for extreme winter conditions however, they are made of a specially formulated compound of rubber that is able to stay relatively flexible in conditions lower than 7°C. They tend to come with a slightly more aggressive tread pattern to help evacuate more snow and water from the tread, increasing traction in winter conditions. They are recognized by Transport Canada as a safe tire in most snowy conditions and carry the Alpine (3 Peak Mountain/Snowflake) Logo. Most insurance providers either require or offer a discount for drivers who have tires with the Alpine logo. All-Weather is a great economical option for drivers who do not want to bear the cost of owning winter tires or do not want to worry about the yearly tire change-over. The downside to All-Weather is they generally will not last as long as the combination of All-Season & Winter. This is evident in the tread warranties of All-Weather compared to All-Season tires.  Click here for an excellent video on head-to-head tire comparisons.


When it comes to Trucks, SUVs and CUVs, All-Terrain tires can be a huge benefit. All-Terrain is a combination of highway tires (H/T) and mud tires (M/T). This combination works well in most weather conditions, most gravel and mud conditions and all-around daily driving. They typically come with a semi-aggressive tread pattern which not only gives you that aggressive look but is offers great functionality in a few aspects. In most cases they are equipped with a wraparound tread pattern which extends several inches up the sidewall, offering more sidewall protection and traction on gravel and mud surfaces. (See image on the left).

In some cases, these tires also come with the Alpine (3 Peak Mountain/Snowflake) logo giving it the same classification as an All-Weather tire for even more benefits. This tire can be an all-year solution for your truck, SUV, CUV or all-wheel drive vehicle. Ask one of our tire specialists about these tires today!


Winter tires are the best and safest option in the winter months. There are a number of factors that contribute to the performance of winter tires. Winter tires are specially formulated to remain soft and flexible in even the coldest temperatures winter can bring. The tread pattern tends to be more aggressive, has better and more effective “siping” and the tread blocks are more “jagged” to aid in evacuating snow and water from the tread. See the image on the right.

If you look at each tread block, you will notice how “jagged” the edges are and how many “sipes” each block has. As your tire navigates through snow, snow packs itself into the spacing between each tread block. The edges help to knock the snow loose so it can be evacuated from the tread blocks. Sipes are those “zig-zag” lines you see in the tread. As the tire makes contact with the ground, these sipes open and close to help remove snow and water from the contact patch. This allows for maximum traction under acceleration and maximum bite when braking. Click here to watch an excellent visual description of this. All of these feature’s aid in making sure your winter tires have the most contact with the road surface keeping you safe and in control. Having a dedicated set of winter tires also prolongs the life of your All-Season tires because they are not being used all year round, splitting the duties between both sets. On a final note, winter tires are too soft and flexible to perform well in warm conditions. In temperatures above 7°C this can lead to premature wear and decreased performance. Due to this, it is recommended to use your winter tires below 7°C. Click here for an excellent video on head-to-head tire comparisons.

Load and Speed Ratings

With so many vehicles that vary in size, weight and performance, tire manufactures label each tire with a load and speed rating. The load rating tells us how much weight each individual tire can handle. This is important because if a tire is installed on a vehicle that exceeds the weight rating of the tire, the tire is susceptible to premature wear and a potential blow-out. The speed rating tells us the maximum speed the tire can travel at before a failure can occur. Let’s look at an example. A 2023 Dodge Charger SXT with P245/45R20 has a load/speed rating of 99V. If we look at the charts below, we can tell how much weight the tires can handle and the maximum speed. A load rating of 99 can handle 1709 lbs each. If we multiply 1709 lbs by 4 tires we get 6,836 lbs. The speed rating is V which means these tires can handle up to 240km/h. This information becomes important for drivers that may want to take their vehicle to a local race track, or drivers that plan on purchasing a tow-behind trailer that can add substantial weight to the vehicle. This is something we always factor in when deciding on which tires will suit your driving needs best.
