You're ready to replace the factory tires on your beloved Mazda CX-5, but which new tires are the best option to choose? The tires Mazda chose for the CX-5 from the factory may not be the best choice for your driving style or your location, so it’s very important to do your research before choosing any old tire brand.
Car Talk recommends all the excellent tire options below.

What tires are on my Mazda CX-5? The current generation CX-5 is sold in multiple trims with several tire sizes:

We’ve recommended three replacement tires in 17- and 19-inch sizes, in budget, moderately priced and cost-no-object varieties. Whether your pockets are deeper than the Mariana trench or Ebenezer Scrooge considers you a role model, don’t worry; we’ve got you covered. All of these tires have ratings of four-stars or higher based on consumer surveys:
There are two regular milestones that will suggest that it’s time to replace the tires, not only on your CX-5, but any vehicle in your driveway: Time and mileage.
Considering most drivers cover between 12,000 and 15,000 miles per year, the vast majority of CX-5 owners are going to be past the mileage that their original equipment tires were intended to cover before they’ll go past the tire’s usable age.
The life of your tire can be somewhat predicted by its UTQG (Uniform Tire Quality Grade) rating. Tire manufacturers apply their own grades to tires for treadwear, traction and temperature. When you’re researching tires online, a UTQG will come up next to the tire name in three digits and a number (ex. 500 A A).
You can glean a bit of info from the tires by reading this rating:
Original equipment Michelin Crossclimate SUV tires on the CX-5 earn a decent 580 AA UTGQ rating. Unless they are damaged, these tires could last as long as 58,000 miles before you need to replace them.
The other consideration is time. Each tire has a raised date code on the sidewall. The number begins with the letters “DOT” followed by 12 digits in three four-digit groups. The date code is the third group of four digits. To decipher the date of your tires, the first two digits represent the WEEK the tire was produced, and the second two digits represent the YEAR.
For example, if your tire’s date code is 3217, that indicates the tire was manufactured in the 37th week of 2017, or some time between September 11 and 17th that year.
Once tires go beyond five years old, it’s time to consider replacing them. Tires are made up not just of rubber and steel or kevlar belts, but chemicals that help the tires resist UV rays, temperature changes and a lot of other environmental hazards. Those chemicals start to break down after five years or so, and the tires aren’t doing the job that they need to do.
There’s no harm in replacing your tires with the shoes it came with from the factory. However, depending on what kind of driver you are, there are significant reasons to purchase something different.
You only need to purchase ONE set of tires for your car every four years or so, depending on how much you drive. When an auto manufacturer purchases tires, they buy them by the hundreds of thousands. For the manufacturer, the decision to choose a supplier one brand or another comes down to a price point.
Looking at reviews for tires, it’s easy to see that many people prefer to replace the OE tire with a better, more focused upgrade. The CX-5’s factory tires aren’t rated as well as many other choices, and there are several other options that last longer and have better fuel economy ratings.
Depending on the year and model, you may be shopping tires to fit anything between 15-inch for older models to 19-inch wheels with various widths and sidewall sizes along the way. It is possible to change the wheel and tire sizes, but a general rule of thumb is to keep the total diameter of wheel and tire the same. So, that means that downsizing an 18-inch wheel to a 17-inch wheel would include a proportionate upsizing of the tire sidewall to compensate.
Downsizing wheels has its advantages. Benefits include:
On the other side of the coin, going up in wheel size has its benefits:
When reading tire sizes, it’s important to understand what the numbers mean. The Mazda CX-5’s 17-inch wheels come with P225/65R17 106V XL all-season tires:
You may have noticed that the Mazda CX-5’s two tire sizes have different diameters and also different aspect ratios. Generally, automakers choose tires that have the same outer diameter. This allows them to have only one speedometer setting.
Now that you know what comes on a new CX-5 and how to read the size numbers, let’s look at the different types of tires available to you. Depending on the type of driving you’re doing, where you live, and the weather, you have a variety of choices for tire types:

You should expect 50,000 miles out of a set of tires. On the outside, you’re looking at 70,000 miles, but you should always be measuring tires by tread depth, not mileage.
That depends on the trim level. Sport and Touring trims have P225/65R17 tires. Grand Touring and Grand Touring Reserve trims have P225/55R19.
Check inside your driver’s side door for a white and yellow label that will tell you the exact tire pressure recommendations for your CX-5model. That tire pressure can also change depending on the load of passengers you’re carrying, as well as the cargo load. Note that the pressure on the tire itself is never the correct setting, but rather a maximum.
Rotating tires is more about the tire than it is about the car. A typical rotation interval is somewhere between 5,000 and 7,000 miles, though specific cars and tires may change those numbers a bit. The CX-5 is either a rear-wheel or four-wheel drive-based car, so the rear tires will be worn more quickly than the rears. Do not blow off this service.
Your Mazda CX-5 should have come equipped with a compact spare tire and changing tools in the trunk. In this case, you already have everything you need to physically change the tire, but you may want to carry an extra roadside emergency kit with an upgraded lug wrench, jumper cables, and emergency markers just in case.
