The 2020 Mazda 3 blends compact-car practicality with the sharper design and more upscale road manners that made this generation stand out in the modern small-car market. Whether in sedan or hatchback form, it appeals to owners who care as much about appearance and driving feel as everyday usability. Tire fitment centers on two radial sizes, 205/60R16 and 215/45R18, and the first step is matching the tire to the exact trim and wheel package. From a traditional whitewall look on the 16-inch size to performance-oriented blackwall choices on the 18-inch size, the selection path depends on style, wheel diameter, and how the car is actually set up today.
Which Tire Size Is Right for The 2020 Mazda 3
The 2020 Mazda 3 uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Some versions use a 16-inch wheel with 205/60R16 tires, while others use an 18-inch wheel with 215/45R18 tires. Before choosing a tire, confirm the specific trim and make sure the car still has the wheel size it was set up to use.
Fit(s): Hatchback, Preferred Hatchback, Preferred Sedan, Premium Hatchback, Premium Sedan, and Select Sedan
Construction: Radial|Rim: 18 in
215/45R18 is a modern metric radial size in which 215 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2020 Mazda 3, this size is used on specific hatchback and sedan trims equipped with 18-inch wheels. Available choices here lean toward a more performance-focused presentation, with BFGoodrich options in blackwall form and g-Force series offerings. This size is the one to evaluate when the car has the larger wheel package and the goal is to retain that lower-profile look.
205/60R16 is also a modern metric radial size, with 205 millimeters of nominal section width, a 60-series profile, radial construction, and a 16-inch rim diameter. On the 2020 Mazda 3, this size applies to versions equipped with the smaller 16-inch wheel setup rather than the 18-inch package. The available product choice in this size has a very different character, using an American Classic radial with a 1.50 inch whitewall and asymmetrical tread styling. It is the relevant size to consider when preserving the 16-inch fitment and confirming the wheel package is still original to the car.
Tire fitment for the 2020 Mazda 3 varies by sub-model rather than staying uniform across the full range. Checking the exact sedan or hatchback trim matters because the car may use either a 16-inch or 18-inch wheel package, and the tire size follows that setup.

2020 Mazda 3 Hatchback
The 2020 Mazda 3 Hatchback uses the 215/45R18 radial fitment. Tire selection here centers on keeping the 18-inch wheel setup and comparing blackwall performance-oriented choices within that size.
The 2020 Mazda 3 Preferred Hatchback also uses 215/45R18 radial tires. That keeps the decision focused on 18-inch-wheel compatibility, tire series differences, and the type of road feel and appearance wanted from the replacement tire.
The 2020 Mazda 3 Preferred Sedan uses the 215/45R18 radial size as well. The practical next step is confirming that the sedan still has its 18-inch wheels before comparing available blackwall options in that size.
The 2020 Mazda 3 Premium Hatchback stays with the 215/45R18 radial fitment. That means the key buying decision is not the basic size code, but which 18-inch tire best suits the car's intended use and presentation.
The 2020 Mazda 3 Premium Sedan uses 215/45R18 radial tires. Owners should focus on matching the 18-inch wheel package and then comparing available series and specification differences within that size.
The 2020 Mazda 3 Sedan uses the 205/60R16 radial size rather than the 18-inch setup found on several other trims. Tire choice here should start with confirming the 16-inch wheels and then deciding whether the available whitewall presentation suits the car's current look.
The 2020 Mazda 3 Select Sedan uses the 215/45R18 radial fitment. That places the emphasis on 18-inch wheel confirmation and selecting among the available blackwall radial options for this specific setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire questions for the 2020 Mazda 3 usually come down to trim-specific size, 16-inch versus 18-inch wheel fitment, and how the available product styles differ. The answers below focus on exact size selection, product character, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2020 Mazda 3?
The 2020 Mazda 3 uses two tire sizes: 205/60R16 and 215/45R18. The correct size depends on the exact sub-model and wheel package. The Sedan uses 205/60R16, while the Hatchback, Preferred Hatchback, Preferred Sedan, Premium Hatchback, Premium Sedan, and Select Sedan use 215/45R18.
The most important step is confirming whether the car has 16-inch or 18-inch wheels before choosing a replacement tire. Many Mazda 3s remain stock, but wheel changes can happen over time, and the tire size must match the actual rim diameter on the car.
What size rim does a 2020 Mazda 3 use?
A 2020 Mazda 3 uses either a 16-inch or 18-inch rim, depending on the sub-model. The 205/60R16 fitment belongs on a 16-inch wheel, while the 215/45R18 fitment belongs on an 18-inch wheel. Both are radial tire applications, but they are not the same wheel setup.
Checking the wheel diameter matters before anything else because tire size selection starts there. A tire for a 16-inch rim cannot be used on an 18-inch rim, and the reverse is also true, so visual confirmation of the wheel setup is always worthwhile.
Do all 2020 Mazda 3 sub-models use the same tire size?
No, the 2020 Mazda 3 does not use one tire size across every sub-model. Most of the covered hatchback and upper-trim sedan versions use 215/45R18, while the 2020 Mazda 3 Sedan uses 205/60R16. The difference follows the wheel package fitted to each version.
That means trim identification is an essential part of buying tires for this car. If the badge, wheel style, or prior ownership history leaves any doubt, check the actual tire sidewall and wheel diameter on the vehicle before selecting a replacement.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Mazda 3?
Start with the correct size for the exact 2020 Mazda 3 sub-model: 205/60R16 or 215/45R18. From there, compare construction, sidewall style, tire series, rim-width compatibility, and other product characteristics that affect how closely the tire matches the wheel setup and intended appearance.
A 16-inch Sedan and an 18-inch Hatchback are not making the same tire decision, even though they share the same model name. It helps to match the tire choice to the car's current wheel package, how it is driven, and whether the goal is a performance-oriented blackwall look or a more distinctive whitewall presentation.
What sidewall styles are available for 2020 Mazda 3 tires?
Two sidewall styles appear in the available 2020 Mazda 3 tire choices: Blackwall and Wide Whitewall. The 215/45R18 options are blackwall BFGoodrich radials, while the 205/60R16 option is an American Classic radial with a 1.50 inch wide whitewall.
That makes sidewall style part of the selection process, not just a cosmetic detail. Blackwall suits the 18-inch fitment's modern, lower-profile presentation, while the whitewall 16-inch option creates a very different visual effect, so appearance should be weighed alongside size and wheel compatibility.
What brands offer tires for the 2020 Mazda 3?
BFGoodrich and American Classic both offer tires for the 2020 Mazda 3 within the available fitments. BFGoodrich covers the 215/45R18 size with g-Force series blackwall radials, while American Classic appears in 205/60R16 with a radial featuring a wide whitewall treatment.
Brand choice is tied closely to size on this vehicle, so the exact trim and wheel diameter still come first. Once the correct fitment is confirmed, compare each brand's available series, sidewall presentation, and rim-width specifications to narrow the selection appropriately.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Mazda 3?
A period-style approach on a 2020 Mazda 3 starts with keeping the correct original-size format for the wheel package already on the car. That means 205/60R16 for the Sedan or 215/45R18 for the trims that use 18-inch wheels, then choosing a tire whose sidewall look fits the appearance goal.
The available products create two very different visual directions. The 18-inch BFGoodrich choices keep a contemporary blackwall presentation, while the 16-inch American Classic adds a wide whitewall look, so appearance decisions should follow the actual wheel setup rather than trying to force one style onto the wrong rim size.
How does tire construction affect the appearance of a restored 2020 Mazda 3?
Tire construction is less of an appearance divide on a 2020 Mazda 3 than on older collector cars because both primary fitments here are radial. The bigger visual change comes from size, profile, and sidewall treatment, especially the contrast between the blackwall 18-inch choices and the wide whitewall 16-inch option.
For an appearance-minded project, the wheel package drives the look just as much as the tire itself. Keeping the correct 16-inch or 18-inch setup usually matters more than chasing a construction change, and sidewall style will do the most to shape the finished presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mazda 3?
Yes, modifications can affect tire fitment on a 2020 Mazda 3 even when the replacement tire matches one of the stock sizes. Wheel diameter, wheel width, offset changes, suspension lowering, and body or fender alterations can all change the clearance picture around a 205/60R16 or 215/45R18 tire.
A car that still has its original wheel package is usually a much simpler fitment decision than one with aftermarket wheels. Any time the setup has been changed, it is smart to check steering clearance, fender room, and the actual wheel dimensions before selecting a tire.
What should I inspect before driving a 2020 Mazda 3 on new tires?
Before road use, inspect tire pressure, bead seating, valve stems, lug torque, and the basic condition of the wheels. It also helps to look for any rubbing marks, sidewall contact, or uneven spacing that might point to a wheel, suspension, or installation issue after fitting new tires.
A short, careful test drive is a useful follow-up before settling into normal use. Listen for contact over bumps or at full steering lock, and recheck pressure after the first miles so the 2020 Mazda 3 starts out on the correct size with the setup behaving as expected.
How often should tires on a 2020 Mazda 3 be inspected?
Tires on a 2020 Mazda 3 should be inspected regularly rather than only when a problem appears. Look for uneven tread wear, cuts, punctures, bulges, cracking, and air loss, and make a point of checking them before longer drives or any season change that can alter pressure noticeably.
Routine inspection is especially helpful on a car that may have seen wheel changes or has gone through alignment or suspension work. Catching wear or clearance issues early helps preserve the correct 205/60R16 or 215/45R18 fitment and reduces the chance of discovering a problem on the road.
