The 2013 Mazda 6 sits at an interesting point in the model’s history, blending midsize sedan practicality with the sharper road manners and more athletic character that helped Mazda stand apart in the segment. For this exact model year, tire fitment depends on trim, with 205/65R16, 215/55R17, and 235/45R18 radial sizes used across the range. That makes the first decision less about brand loyalty and more about confirming the car’s wheel diameter and sub-model. Available choices center on modern blackwall radial performance tires, so the focus shifts to selecting the right size, rim-width compatibility, and overall driving character for the way the car is used.
Which Tire Size Is Right for The 2013 Mazda 6
The 2013 Mazda 6 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they are tied to different 16-inch, 17-inch, and 18-inch wheel setups, so confirming the trim level and the wheels currently on the car is the first step before comparing tire options.
In 235/45R18, 235 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2013 Mazda 6, this size is used on specific higher-wheel configurations and keeps the fitment centered around an 18-inch rim. Available choices in this size come from BFGoodrich in blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This size makes the most sense when the car already carries the correct 18-inch wheels and the goal is to stay with the intended trim-specific fitment.
In 205/65R16, 205 is the nominal section width in millimeters, 65 is the aspect ratio, R means radial construction, and 16 indicates a 16-inch rim. This is a modern metric radial size with a taller sidewall profile than the 17-inch and 18-inch alternatives used elsewhere in the 2013 Mazda 6 lineup. Its role is specific to the sub-models equipped with 16-inch wheels, so it should be treated as a trim-dependent fitment rather than a universal Mazda 6 size. Choosing this size starts with confirming that the car still has the proper 16-inch wheel setup and has not been changed to a different diameter.
In 215/55R17, 215 is the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. For the 2013 Mazda 6, this size bridges the gap between the taller 16-inch fitment and the lower-profile 18-inch setup, while remaining tied to a 17-inch wheel. BFGoodrich options in this size are available in blackwall form, including the g-Force Comp 2 AS and g-Force Phenom T/A series. It is the right size to evaluate when the car is a 17-inch-wheel trim and the goal is to stay with that wheel diameter rather than convert to another setup.
Tire fitment for the 2013 Mazda 6 varies by sub-model, so the correct choice starts with identifying the exact trim and wheel diameter on the car. Several sub-models share the same 18-inch fitment, while others use distinct 16-inch or 17-inch radial sizes.

2013 Mazda 6 S
The 2013 Mazda 6 S uses the 235/45R18 radial fitment tied to an 18-inch wheel setup. Tire selection here centers on staying with the correct wheel diameter and comparing available blackwall performance-oriented radial options within that size.
The 2013 Mazda 6 i Grand Touring also uses 235/45R18 radial tires on an 18-inch wheel. That keeps fitment straightforward, but it still helps to confirm the car has not been switched to a different wheel package before choosing among the available tire series.
The 2013 Mazda 6 i Sport uses the 205/65R16 radial size, making it the 16-inch-wheel configuration in the lineup. Tire selection should begin with verifying that the car still wears its proper 16-inch wheels rather than an upgraded or aftermarket setup.
The 2013 Mazda 6 i Touring uses the 215/55R17 radial fitment with a 17-inch wheel. That means the key decision is not between multiple primary sizes for this trim, but between the available tire series that match the 17-inch setup.
The 2013 Mazda 6 i Touring Plus uses the same 235/45R18 radial size found on other 18-inch-wheel versions of the car. Buyers should focus on the existing wheel diameter, rim-width suitability, and the character of the available performance-oriented blackwall tires.
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 Size & Fitment
What tire size fits a 2013 Mazda 6?
The 2013 Mazda 6 uses three different tire sizes depending on sub-model: 205/65R16, 215/55R17, and 235/45R18. All are radial fitments, but they are not interchangeable as one universal size for every version of the car because each one corresponds to a specific wheel diameter and trim-level setup.
The practical first step is identifying the exact sub-model and confirming the wheel diameter currently on the car. A Mazda 6 that has had wheel changes over the years may no longer match its original trim-based setup, so the tire choice should be matched to the actual wheels in service rather than assumed from the badge alone.
What size rim does a 2013 Mazda 6 use?
A 2013 Mazda 6 uses 16-inch, 17-inch, or 18-inch rims depending on the sub-model and tire size. The 205/65R16 fitment uses a 16-inch rim, the 215/55R17 fitment uses a 17-inch rim, and the 235/45R18 fitment uses an 18-inch rim.
Wheel diameter is the key fitment checkpoint because the tire must match it exactly. Before ordering replacement tires, inspect the wheels currently on the car and confirm their diameter and width, especially if the Mazda 6 has aftermarket wheels, a previous trim-level wheel swap, or a secondhand history that may have changed its original configuration.
Why does the 2013 Mazda 6 have more than one tire size?
The 2013 Mazda 6 has more than one tire size because different sub-models were equipped with different wheel packages. The i Sport uses 205/65R16, the i Touring uses 215/55R17, and the S, i Grand Touring, and i Touring Plus use 235/45R18.
That means tire selection starts with trim identification rather than jumping straight to brand or series. It is also smart to confirm the actual wheels on the car, since a used Mazda 6 may have been upgraded or swapped to another factory-size wheel set, which changes the tire size you should be comparing.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Mazda 6?
Start with the correct trim-specific size and wheel diameter, since the 2013 Mazda 6 uses 205/65R16, 215/55R17, or 235/45R18 depending on sub-model. From there, compare radial tire options by rim-width compatibility, tire series, weight, and load-related specifications where those details are shown.
The right choice often depends on how the car is actually used. A daily-driven sedan, a weekend commuter, and a lightly modified car can all call for a slightly different balance of fitment discipline and tire character, so checking wheel specs and keeping the selection matched to the current setup is more useful than choosing by name alone.
What sidewall styles are available for 2013 Mazda 6 tires?
The available 2013 Mazda 6 products shown here use a blackwall sidewall style. That applies to the BFGoodrich options offered in the supported 17-inch and 18-inch sizes, giving the car a modern, understated appearance rather than a decorative stripe or raised-letter presentation.
For most buyers, that means the main visual differences come from wheel design and overall tire profile rather than sidewall ornamentation. If appearance matters, make sure the tire size still matches the trim and wheel diameter first, because keeping the correct fitment has a bigger effect on the car’s look and stance than sidewall treatment alone.
What tire series are available for the 2013 Mazda 6?
The available tire series for the 2013 Mazda 6 include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, depending on size. The 235/45R18 fitment has the broadest series coverage, while 215/55R17 is available in selected g-Force series.
Series differences matter because they shape the comparison beyond simple size matching. Once the correct wheel diameter and tire size are confirmed, it makes sense to compare the remaining options by their construction details, rim-width range, and any load or weight figures shown, especially when narrowing choices within one supported size.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Mazda 6?
A period-style choice for a 2013 Mazda 6 starts with keeping the correct trim-based size and wheel diameter intact. Since this model uses modern radial sizes rather than vintage bias-ply fitments, the most authentic-looking result usually comes from preserving the proper 16-inch, 17-inch, or 18-inch setup that matches the sub-model.
Appearance on a car from this era is influenced more by stance, wheel diameter, and sidewall proportion than by decorative sidewall treatments. Before changing sizes for visual reasons, compare the car’s current wheels to its intended trim-level fitment so the tire choice supports the original character of the Mazda 6 without creating avoidable clearance or proportion issues.
Does correct tire fitment matter for a 2013 Mazda 6 restoration?
Correct tire fitment matters on a 2013 Mazda 6 because wheel diameter and tire proportions are part of how the car sits and drives. Using the proper 205/65R16, 215/55R17, or 235/45R18 size for the correct sub-model helps preserve the intended relationship between the tire, wheel, and body.
Even on a newer collector or preservation-minded car, tire choice affects both presentation and usability. Owners aiming for a faithful result should confirm the exact trim and wheel package first, then use marque references, original sales literature, or vehicle-specific records if exact appearance details matter beyond simple size and fitment accuracy.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mazda 6?
Yes, modifications can affect tire fitment on a 2013 Mazda 6. Wheel swaps, suspension changes, lowering, alignment changes, or body modifications can alter how a 205/65R16, 215/55R17, or 235/45R18 tire sits in the wheel opening and whether it has adequate clearance during steering and suspension travel.
That is why the tire decision should be tied to the car’s actual current setup, not just its original trim designation. A Mazda 6 with aftermarket wheels should have wheel diameter and width confirmed before replacement tires are chosen, and any signs of rubbing or uneven wear should be addressed before regular road use.
What should I inspect before driving a 2013 Mazda 6 on new tires?
Before driving a 2013 Mazda 6 on new tires, inspect wheel condition, verify the tire size matches the wheel diameter, and confirm there is no interference at full steering lock or normal suspension movement. It also helps to look over valve stems, check inflation pressure, and make sure the tires are mounted evenly and balanced properly.
A quick road-use inspection should also include alignment-related wear patterns on the old tires, because those can point to suspension or steering issues that will affect the new set. Any vibration, pulling, or rubbing after installation deserves attention early, especially on cars that have seen wheel changes or suspension work.
How often should tires on a 2013 Mazda 6 be inspected?
Tires on a 2013 Mazda 6 should be inspected regularly, not just when replacement is due. Frequent checks for tread wear, sidewall cracking, cuts, punctures, bulges, and air loss are especially useful on a car that may alternate between daily use and longer parked periods.
Inspection is also a good time to confirm that all four tires still match the intended setup in size and condition. Uneven wear can signal alignment or suspension issues, while gradual pressure loss may point to wheel or valve stem problems, so routine checks help preserve both tire life and predictable road behavior.
