The 2010 Mazda 6 sits in the midsize sedan segment with a more athletic character than many of its direct rivals, giving it a strong appeal for drivers who want everyday practicality without giving up responsive road manners. Tire choice matters on this car because fitment varies by trim, with 205/65R16, 215/55R17, and 235/45R18 radial sizes used across the lineup. That means the first step is matching the tire to the exact sub-model and wheel diameter. Available choices center on modern blackwall radial performance-oriented series from BFGoodrich. For the best result, confirm the car's current wheel setup before choosing between comfort-focused, balanced, or more aggressive tire character.
Which Tire Size Is Right for The 2010 Mazda 6
The 2010 Mazda 6 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are metric radial fitments, but they are tied to different trims and 16-inch, 17-inch, or 18-inch rims. Before selecting a tire, confirm which version of the Mazda 6 you have and verify the wheels currently on the car, especially if it has ever been changed from stock.
235/45R18 is a metric radial size that uses a 235-millimeter section width, a 45-series profile, and an 18-inch rim diameter. On the 2010 Mazda 6, this size is used on certain upper trims and gives the car its largest wheel-and-tire package among the primary fitments. Available choices in this size include BFGoodrich blackwall radial tires in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is the one to evaluate when the car already wears 18-inch wheels and the goal is to keep the intended trim-level fitment and overall stance.
215/55R17 is a metric radial size with a 215-millimeter section width, a 55-series aspect ratio, and fitment for a 17-inch wheel. It serves as the middle fitment in the 2010 Mazda 6 range, making it important for owners whose car falls between the base 16-inch setup and the larger 18-inch package. BFGoodrich offers blackwall radial choices in this size through the g-Force Comp 2 AS and g-Force Phenom T/A series. This is the right size to focus on when your Mazda 6 has factory-type 17-inch wheels and you want to stay with the proper trim-specific tire format.
205/65R16 is a metric radial size that combines a 205-millimeter section width with a 65-series profile on a 16-inch rim. On the 2010 Mazda 6, it is used on specific i Sport trims and represents the smallest primary wheel diameter among the available fitments. Its taller profile relative to the other sizes makes wheel confirmation especially important before ordering, since a move to a different rim diameter changes the tire size entirely. Choose this size when the car retains its 16-inch wheel setup and the goal is to preserve the proper fitment for those trims.
Tire fitment on the 2010 Mazda 6 varies by sub-model rather than staying consistent across the full lineup. Checking the exact trim matters because the car was fitted with three different radial sizes on three different rim diameters.

2010 Mazda 6 S Grand Touring
The 2010 Mazda 6 S Grand Touring uses the 235/45R18 radial fitment. That makes 18-inch wheel confirmation the key step before choosing among the available blackwall performance-oriented tire options in this size.
The 2010 Mazda 6 S Sport uses the 215/55R17 radial size. Tire selection here centers on keeping the correct 17-inch fitment and comparing the available BFGoodrich series for the driving feel you want.
The 2010 Mazda 6 S Touring shares the 235/45R18 radial size with the S Grand Touring. Buyers should confirm that the car still has its 18-inch wheels, then compare the available blackwall tire series within that fitment.
The 2010 Mazda 6 i Grand Touring uses the 215/55R17 radial fitment. Staying with the proper 17-inch wheel size is the main concern, followed by selecting the tire series that best matches how the car is driven.
The 2010 Mazda 6 i Sport uses the 205/65R16 radial size. This trim's tire choice begins with confirming the 16-inch wheel setup, since moving to a larger wheel would require a different tire size entirely.
The 2010 Mazda 6 i Sport SV also uses the 205/65R16 radial fitment. Owners should match that 16-inch setup carefully and verify the current wheels if the car has been changed since new.
The 2010 Mazda 6 i Touring uses the 215/55R17 radial size. The practical decision is to confirm 17-inch wheels first, then compare the available tire series in that size rather than looking at the 16-inch or 18-inch options.
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 2010 Mazda 6?
The 2010 Mazda 6 uses three primary tire sizes: 205/65R16, 215/55R17, and 235/45R18. The correct one depends on the exact sub-model, since different trims were fitted with different wheel diameters and matching radial tire sizes.
The practical first step is identifying the trim and checking the wheels currently on the car. An i Sport or i Sport SV may use 205/65R16, several i and S trims use 215/55R17, and S Touring or S Grand Touring use 235/45R18. If the car has aftermarket wheels, rely on the actual wheel diameter and the intended fitment rather than trim name alone.
What size rim does a 2010 Mazda 6 use?
A 2010 Mazda 6 may use 16-inch, 17-inch, or 18-inch rims, depending on sub-model. The 205/65R16 tire fits a 16-inch rim, 215/55R17 fits a 17-inch rim, and 235/45R18 fits an 18-inch rim.
That rim diameter is the non-negotiable part of tire selection, because a tire must match the wheel's bead seat diameter. Before choosing a replacement, check the marking on the tire sidewall and confirm the wheel size on the car today. Trim-based fitment is helpful, but wheel swaps are common enough that measuring the actual setup is the safer approach.
Why does the 2010 Mazda 6 have more than one tire size?
The 2010 Mazda 6 was offered in several sub-models, and those trims used different wheel-and-tire packages. That is why the car appears with 205/65R16, 215/55R17, or 235/45R18 rather than one universal size across the entire lineup.
For a buyer, that means trim identification matters more than the model name by itself. The three sizes stay close in overall diameter, but they are built around different wheel diameters and different section widths. Matching the car's exact sub-model and present wheel size helps avoid ordering a tire that is correct for a different Mazda 6 configuration.
Choosing the Right Tire
What should I consider when choosing a 2010 Mazda 6 tire?
Start with the correct size for the car's trim and wheel diameter, since the 2010 Mazda 6 uses 205/65R16, 215/55R17, or 235/45R18. After that, compare tire construction, rim-width compatibility, and the series available in that exact size.
The available products here are all radial blackwall BFGoodrich tires, but they are not identical. Series differences, load figures where shown, and rim-width ranges can help narrow the choice based on how the car is driven. A daily-driven sedan with original wheels calls for a different selection process than a Mazda 6 running changed wheels or a more aggressive tire setup.
What sidewall styles are available for 2010 Mazda 6 tires?
The available 2010 Mazda 6 products in these fitments use a blackwall sidewall style. That keeps the appearance clean and modern, which suits the Mazda 6's factory-era presentation without introducing whitewall or raised-letter styling.
Because the available products stay within one sidewall treatment, the visual decision is simpler than on many collector vehicles. The bigger differences come from size, tire series, and wheel compatibility. Buyers who want to keep the car looking close to its original period should focus on the proper trim-specific tire size first, then use sidewall style as a secondary consideration.
What tire series are available for the 2010 Mazda 6?
The available tire series for the 2010 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 selection, while 215/55R17 includes fewer choices.
Series names matter because they help separate one tire's intended character from another even when the size is the same. A buyer comparing products should still keep the correct fitment first, then look at details such as rim-width range, load figure where shown, and the overall role of the tire within the car's current wheel and suspension setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mazda 6?
Yes, modifications can change what fits a 2010 Mazda 6 even when the original trim-specific size is known. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body modifications can all affect clearance and may move the car away from its original 16-inch, 17-inch, or 18-inch setup.
A modified car should be checked as it sits, not just by model and trim. Measure wheel diameter and width, confirm the tire already on the car, and inspect steering and fender clearance through the full range of motion. That is especially important when moving between the Mazda 6's three primary fitments, because each one is built around a different wheel diameter.
What should I inspect before driving a 2010 Mazda 6 on new tires?
Before road use, inspect the wheel size, tire pressure, lug nut torque, and basic tire-to-body clearance on the 2010 Mazda 6. It is also smart to confirm that the tire size matches the trim and that the new tires are seated properly on the correct rim width.
A short test drive should include checking for vibration, rubbing, pull, or unusual steering feel. After that, recheck pressure and look over the sidewalls and tread for any signs of contact. On a car with prior wheel or suspension changes, those checks matter even more because a tire that mounts correctly can still run into clearance issues once the car is moving.
How often should tires on a 2010 Mazda 6 be inspected?
Tires on a 2010 Mazda 6 should be inspected regularly for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage. A quick visual check before longer drives and a more thorough inspection during routine maintenance helps catch problems early.
This matters whether the car is a daily driver or a lower-mileage second vehicle. Tire condition can change even when tread depth still looks acceptable, especially if the car sits for stretches of time. Keeping pressures consistent and watching for unusual wear patterns can also reveal alignment, suspension, or wheel issues before they become more expensive problems.
