The 2021 Mazda 3 sits in the modern compact segment with a reputation for sharper styling and a more refined feel than many everyday small cars. Whether sedan or hatchback, this generation blends commuter practicality with a driver-focused character that makes tire choice more important than a simple maintenance item. Fitment centers on two radial sizes, 205/60R16 and 215/45R18, depending on the exact sub-model and wheel package. Available choices range from a whitewall American Classic in 205/60R16 to BFGoodrich blackwall performance-oriented options in 215/45R18. The key is matching the correct size to the car's trim level, rim diameter, and the look or road manners you want to preserve.
Which Tire Size Is Right for The 2021 Mazda 3
The 2021 Mazda 3 uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both are radial fitments, but one uses a 16-inch rim and the other uses an 18-inch rim, so confirming the specific trim and the wheel currently on the car is the first step before comparing tire style, series, or brand.
Fit(s): 2.0 Sedan, 2.5 S Hatchback, and 2.5 S Sedan
Construction: Radial|Rim: 16 in
A 205/60R16 tire uses a 205-millimeter section width, a 60-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2021 Mazda 3, this size is used on specific sedan and hatchback configurations that run the smaller wheel package. In this size, the main visible product distinction is an American Classic radial with a 1.50-inch wide whitewall and an asymmetrical tread design. It is the size to focus on when the car has 16-inch wheels and you want to keep the correct dimensional fitment while choosing a more traditional sidewall presentation.

Construction: Radial|Rim: 18 in
A 215/45R18 tire uses a 215-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. This size applies to the larger-wheel 2021 Mazda 3 configurations, including several Preferred, Premium, Select, and Turbo sub-models. Available choices here center on BFGoodrich blackwall tires in the g-Force Comp 2 AS and g-Force Phenom T/A series, giving the buyer a choice between different modern radial performance-oriented product lines. It is the right fitment to evaluate when the car is equipped with 18-inch wheels and the goal is to stay with the correct wheel diameter and trim-level sizing.
Tire fitment for the 2021 Mazda 3 varies by sub-model, and the split is tied directly to wheel diameter. Checking the exact trim matters because the car uses either a 16-inch or 18-inch radial setup, and that determines which tires belong on it.

2021 Mazda 3 2.0 Sedan
The 2021 Mazda 3 2.0 Sedan uses the 205/60R16 radial fitment on a 16-inch wheel package. Tire selection here centers less on construction change and more on choosing the right overall style, sidewall look, and wheel-compatible product within that size.
The 2021 Mazda 3 2.5 S Hatchback also uses the 205/60R16 radial size. That makes wheel diameter confirmation straightforward, after which the main choice becomes whether a traditional whitewall presentation suits the car's intended appearance and use.
The 2021 Mazda 3 2.5 S Sedan stays with the 205/60R16 radial setup. Buyers in this sub-model should match the 16-inch fitment first, then compare the available tire's sidewall styling and rim-width compatibility against the wheels currently on the car.
The 2021 Mazda 3 2.5 Turbo Hatchback uses the 215/45R18 radial size tied to an 18-inch wheel. Tire choice in this sub-model is about staying with the correct low-profile fitment while comparing the available BFGoodrich series and confirming the wheel setup remains stock.
The 2021 Mazda 3 2.5 Turbo Premium Plus Hatchback uses the 215/45R18 radial fitment. That means selection should begin with the 18-inch wheel package, then move to comparing blackwall tire series and checking for any wheel or suspension changes that could affect fitment.
The 2021 Mazda 3 2.5 Turbo Premium Plus Sedan also uses 215/45R18 radials. This keeps the focus on choosing among the available modern blackwall options while making sure the car still has the correct 18-inch wheels for the original trim-level sizing.
The 2021 Mazda 3 2.5 Turbo Sedan runs the 215/45R18 radial size. Tire selection here is mainly a matter of matching the 18-inch fitment, then choosing between the available BFGoodrich product lines based on intended driving character and wheel compatibility.
The 2021 Mazda 3 Preferred Hatchback uses the 215/45R18 radial setup rather than the smaller 16-inch size. That makes trim verification important, especially if the car has seen wheel changes, because the available choices are built around the larger blackwall radial package.
The 2021 Mazda 3 Preferred Sedan uses 215/45R18 radial tires on 18-inch wheels. Once that fitment is confirmed, the decision becomes which blackwall series best matches the car's use while staying within the proper wheel-width range for the size.
The 2021 Mazda 3 Premium Hatchback fits the 215/45R18 radial size. Buyers should verify the car still wears its 18-inch wheel package, then compare the available BFGoodrich options by series and other product characteristics rather than by size alone.
The 2021 Mazda 3 Premium Sedan also uses 215/45R18 radials. The practical tire decision is not which diameter to choose, but which available blackwall radial best suits the existing wheels and the way the car will be driven.
The 2021 Mazda 3 Select Hatchback uses the 215/45R18 radial fitment. That places the emphasis on confirming the 18-inch wheel package and then choosing among the available performance-oriented blackwall radials in the correct size.
The 2021 Mazda 3 Select Sedan uses 215/45R18 radial tires. Selection starts with keeping the correct 18-inch fitment in place, then comparing the available tire series and wheel-width compatibility before making a final choice.
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.

Common 2021 Mazda 3 tire questions usually come down to identifying the correct size by sub-model, confirming 16-inch versus 18-inch wheels, and comparing available radial tire styles, brands, and series. The details below also cover fitment checks, appearance choices, and routine road-use inspection points.
Tire Size & Fitment
What tire size fits a 2021 Mazda 3?
A 2021 Mazda 3 uses either 205/60R16 or 215/45R18, depending on the exact sub-model. Both are radial tire fitments, but they are tied to different wheel diameters, so they are not simply alternate sizes for the same setup.
The practical first step is identifying the trim and confirming whether the car has 16-inch or 18-inch wheels. A 2.0 Sedan, 2.5 S Hatchback, or 2.5 S Sedan uses 205/60R16, while Preferred, Premium, Select, and Turbo versions use 215/45R18.
What size rim does a 2021 Mazda 3 use?
The 2021 Mazda 3 uses either a 16-inch or 18-inch rim, depending on sub-model. The 205/60R16 tire belongs on a 16-inch wheel, while the 215/45R18 tire belongs on an 18-inch wheel.
Rim diameter should be confirmed before comparing tires because it determines which size family applies to the car. If the Mazda 3 has had aftermarket wheels installed, check the actual wheel markings as well as the trim level so the tire size matches both the car and the wheel.
Why does the 2021 Mazda 3 have more than one tire size?
The 2021 Mazda 3 has more than one tire size because different sub-models use different wheel packages. Some trims use 205/60R16 on 16-inch wheels, while others use 215/45R18 on 18-inch wheels.
That means tire selection starts with configuration, not preference alone. A buyer should verify the exact sedan or hatchback trim and then confirm the actual wheels on the car, especially if it was purchased used, since a wheel change can make the original trim-based fitment less obvious.
Choosing the Right Tire
What should I consider when choosing a tire for a 2021 Mazda 3?
Start with the correct size for the exact sub-model: 205/60R16 for the covered 16-inch setups or 215/45R18 for the covered 18-inch setups. After that, compare construction, sidewall style, tire series, rim-width compatibility, and any load information given for the specific tire.
The 205/60R16 choice leans toward a distinctive wide whitewall appearance, while 215/45R18 centers on modern BFGoodrich blackwall options. Matching the tire to the car's intended use matters too, whether the priority is daily road use, a specific visual style, or staying close to the original wheel package.
What sidewall styles are available for 2021 Mazda 3 tires?
Two sidewall presentations appear across the available 2021 Mazda 3 tires: Wide Whitewall and Blackwall. The 205/60R16 American Classic radial uses a 1.50-inch wide whitewall, while the 215/45R18 BFGoodrich options use a blackwall sidewall treatment.
That difference can shape the look of the car as much as the size itself. A wide whitewall creates a more custom or nostalgic presentation on a 16-inch Mazda 3 setup, while blackwall tires keep the 18-inch trims visually closer to a contemporary sport-compact appearance.
What brands offer tires for the 2021 Mazda 3?
Available tires for the 2021 Mazda 3 come from American Classic and BFGoodrich. American Classic appears in 205/60R16, while BFGoodrich covers the 215/45R18 fitment with g-Force series options.
Brand alone should not make the decision. It is more useful to start with the correct size and wheel diameter, then compare how each tire's sidewall style, tread series, rim-width range, and intended visual character line up with the specific Mazda 3 configuration you are trying to equip.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Mazda 3?
Yes, modifications can affect tire fitment on a 2021 Mazda 3 even when the tire size itself is correct for the original trim. Wheel width, offset, suspension height, and brake or body changes can all influence clearance and overall compatibility.
A Mazda 3 with aftermarket wheels should be checked carefully before selecting between 205/60R16 and 215/45R18 products. Verify actual rim diameter and width, then inspect clearance at the fender, strut, and steering range so the chosen tire suits the car's present setup rather than just its original configuration.
What should I inspect before driving a 2021 Mazda 3 on new tires?
Before driving a 2021 Mazda 3 on new tires, confirm the size matches the sub-model and wheel diameter, then inspect inflation, bead seating, and clearance around the suspension and body. It is also wise to look for any uneven wear signs that could point to alignment or wheel issues.
A short low-speed check drive can reveal rubbing, vibration, or steering pull before the car is used normally. Rechecking tire pressure after installation and making sure lug hardware is properly tightened helps protect the new tires and gives the Mazda 3 a solid baseline for everyday road use.
How often should tires on a 2021 Mazda 3 be inspected?
Tires on a 2021 Mazda 3 should be inspected regularly, not only when tread looks low. Pressure, tread wear pattern, cuts, punctures, sidewall damage, and any signs of air loss are all worth checking on a routine basis.
Regular inspection matters on both 16-inch and 18-inch setups because the correct size alone does not guarantee the tire remains road-ready. Cars driven less often should still be checked for aging and flat-spotting, while daily-driven examples benefit from frequent pressure checks and visual walkarounds to catch issues early.
