Sometimes the difference between a smooth ride and a rough one is the quality of your tires. In this guide, our experts will teach you all the ins and outs of tire types, maintenance, and how to figure out the best set for your vehicle and driving preferences. Read on to find out how to choose the right tires for your vehicle, courtesy of your friends at Shaw GMC.
Key Takeaways
- Always swap out all four tires together for the best performance; mixing different tires is like a recipe for chaos.
- Pay attention to tire details like size, tread-wear, and speed rating—they're key to smooth driving. Get them wrong, and you're in for a rough ride.
- Think about your driving style when upgrading; whether it's performance or touring tires, they can make a world of difference.
- Know your tire types—all-season, summer, or winter tires—to pick the right set for your vehicle, factoring in the weather and your driving habits.
When to Replace Your Tires

Not all tires are created equal, though we've got a little bit of everything here at Shaw GMC to suit your needs.
When it comes to replacing your tires, either you find out that you need to yourself, or the road tells you (not a good thing). Regular checks prevent unexpected blowouts and ensure road safety, so don’t wait until tires are bald.
The easiest way to spot when your wheels need replacing is by looking at the tire tread wear indicators, or wear bars, which signal when tires are worn out by being level with the surface of the tread. You can also use a dime or nickel to check the treads; stick the coin crown-side down into the treads, and if you can see the top of Elizabeth's crown, it's time for a change.
Replace your tires when tread depth hits 4/32 inches, especially in rainy conditions, to maintain effective traction. Keeping an eye on tire tread depth is essential for driving safety. If you're unsure, check out our full article on when to replace your tires for detailed guidance.
How Many Tires Do You Need?
According to our technicians, replacing all four car tires at once guarantees optimal vehicle performance and handling. Consider it a team effort—each tire contributes, and a mismatched tire can disrupt control.
If budget constraints limit you to two new tires, place them on the rear axle to maintain stability and avoid fishtailing. Just make sure they are similar in category to the existing ones to avoid uneven vehicle response.
Mixing and matching tires can lead to uneven wear and unpredictable handling, as though each tire has its own driver. To keep your ride smooth and your peace of mind intact, it's best to replace all four tires whenever possible.
Determining the Right Size
You can find essential details on the tire width, aspect ratio, and rim diameter of your wheels by looking on the tire sidewall for distinct markings. A tire marked “225/50R17”, for example, indicates a width of 225 millimeters, an aspect ratio of 50%, and compatibility with a 17-inch rim.
Tire width influences traction, handling, and the aesthetic appeal of a vehicle. While wider tires offer better grip, however, they can also reduce fuel efficiency. The aspect ratio indicates the tire's sidewall height relative to its width - a higher ratio provides a more comfortable ride by absorbing any bumps or cracks in the road.
And then there’s the rim diameter - miscalculate this, and your tire won’t fit. Verify the load capacity on the tire’s sidewall or your vehicle’s doorjamb placard to ensure the tire can handle your vehicle’s weight. Matching these specifications guarantees optimal performance and safety.
Understanding Tire Types

Special weather-dependent tires will help keep your drives smooth, regardless of the climate.
Just like your wardrobe, a vehicle's wheels should be rotated in and out depending on the season. Winter tires, like a warm coat, are an important step in winterizing your vehicle, equipped with a rubber compound that stays flexible in freezing temperatures to enhance grip. Having a set of dedicated winter tires is vital, especially for navigating those long Alberta winters.
All-season tires are a little more versatile, offering balanced performance for various conditions, suitable for year-round use in mild weather regions.
Summer tires are designed to provide optimal performance in warm weather conditions, offering enhanced grip and handling on both dry and wet roads. They feature a unique tread pattern and rubber compound that maximizes contact with the road, ensuring superior traction and braking capabilities.
For adventurers, mud terrain tires and snow tires, marked with an ‘M+S’ designation, are best suited for muddy and snowy conditions. And let’s not forget the sidewall markings—mountain and snowflake symbols indicate that the tires meet winter traction standards.
Understanding the difference between winter tires, summer tires, and all-season tires will help you select the best tires for your vehicle, whether cruising through downtown Calgary or tackling off-road trails. Your driving conditions and climate will largely dictate your choice, so choose wisely.
Evaluating Tread-Wear Rating
Tread-wear ratings give you a rough idea of how long your tires will last, much like expiration dates on food packages. These numbers range from 100 to over 600, and can be found on the tire's sidewall. A higher rating means the tire wears down more slowly, offering a longer lifespan.
Most tires come with a tread-wear rating between 301 and 400, striking a balance between durability and performance. These ratings are a handy tool for estimating how long your tires will last, helping you assess their value effectively.
These ratings can be a lot to decode; luckily, our service team is always here to help you pick the right tires to avoid costly replacements and ensure more miles and less stress on the road.
Speed Rating and Load Index
The speed rating on a set of wheels lets you know the top speed a tire can safely handle, indicated by a letter at the end of the tire’s service description. For example, a speed rating of "H" means the tire can handle speeds up to 210 km/h. It's crucial to match or exceed the speed rating of your car's original tires to keep things running smoothly and safely.
The load index tells you how much weight a tire can carry, linked to specific weight capacities in pounds. Make sure to pick tires that meet or surpass the load index recommended by your vehicle's manufacturer to keep everything safe and sound.
Comparing Prices and Value
When it comes to tires, you generally get what you pay for. Assessing the total cost of ownership means looking at both the purchase price and how long the tires will last. Though a pricier tire might seem costly upfront, it can often save you money in the long run thanks to fewer replacements.
Comparing budget tires to more expensive options often shows that the latter can lower your overall cost per mile. However, shelling out for high-end tires doesn't always mean you're getting top-notch performance. It's crucial to do some thorough, research-based selection to make the right choice.
Upgrading Your Tires

Speaking to an experienced technician on our team will help narrow down the perfect set of wheels for your car.
Upgrading your tires is a great way to breathe some new life into your car. High-performance tires enhance handling and traction, prioritizing cornering capabilities suitable for sports cars, offering better control and a stiffer, more precise ride.
Touring tires, on the other hand, emphasize comfort for long-distance travel, focusing on reduced road noise and a smooth ride. Prioritize tire characteristics such as comfort, smooth ride, and low road noise when selecting these tires.
Special Considerations: Run-Flat Tires and Performance Tires

Performance-based tires are specially designed for tight turns. With a set of these on, you'll be feeling like Vin Diesel in no time.
When it comes to tires that aren't dependent on the weather, there are also performance-focused options to think about.
Run-flat tires let you keep driving even when they're flat, which can be a real lifesaver if you find yourself in a sketchy situation. However, these tires tend to be pricier to replace and can offer a bumpier ride because of their stiffer sidewalls, so choosing a replacement tire is something you'll want to think through.
Performance tires are all about boosting handling and grip, making them perfect for sports cars or drivers who love sharp cornering. They offer better control and a firmer, more precise ride. But keep in mind, with great performance comes quicker wear and potentially higher costs, which can impact how your tires perform.
