The 2008 Mazda 6 sits in the sport-minded midsize sedan era, blending everyday practicality with the sharper road manners that helped Mazda stand apart from many family cars of its time. Buyers looking at this exact car usually need to sort out trim-level fitment first, because the 2008 Mazda 6 uses either 215/50R17 or 215/45R18 radial tires depending on sub-model. That keeps the decision focused on wheel diameter as much as tire size. Available choices stay performance-oriented, with blackwall BFGoodrich options across multiple g-Force series. The right selection comes down to matching the exact sub-model, confirming the wheel setup on the car, and choosing the tire character that best suits daily driving or a sharper handling feel.
Which Tire Size Is Right for The 2008 Mazda 6
The 2008 Mazda 6 uses two primary tire sizes, and the difference is tied directly to sub-model and wheel diameter. Both are radial metric sizes, but one fits a 17-inch rim and the other fits an 18-inch rim, so the first step is confirming the exact sub-model or checking the wheel diameter already on the car before choosing a tire.
A 215/45R18 tire uses a 215 millimeter section width, a 45-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2008 Mazda 6, this size serves the sub-model fitted with the larger wheel package and keeps the fitment in a modern performance-oriented radial format. Available choices in this size come from BFGoodrich in blackwall form, including g-Force Comp 2 AS and g-Force Phenom T/A series. This is the size to evaluate when the car is equipped with 18-inch wheels and the goal is to stay with the proper rim diameter and overall tire profile for that setup.
A 215/50R17 tire carries the same 215 millimeter nominal width as the 18-inch fitment, but uses a 50-series profile on a 17-inch rim. For the 2008 Mazda 6, this is the primary size used across several sub-models, making it the more common fitment within the range. BFGoodrich options in this size include blackwall selections from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the right starting point when the car retains its 17-inch wheels and the buyer wants to compare tread and series character without changing the basic fitment.
Tire fitment for the 2008 Mazda 6 varies by sub-model, so trim identification matters before anything else. Most covered versions use the 17-inch setup, while the S Grand Touring moves to a different tire size on an 18-inch rim.

2008 Mazda 6 S Grand Touring
The 2008 Mazda 6 S Grand Touring uses the larger 18-inch fitment, which sets it apart from the other covered sub-models. Tire selection here starts with confirming that the car still has its 18-inch wheels, then comparing blackwall BFGoodrich performance-oriented radial choices within that size.
The 2008 Mazda 6 S Sport VE uses the 17-inch radial fitment shared with other covered trims. That makes the decision less about size variation and more about staying with the correct wheel diameter while choosing among the available BFGoodrich blackwall g-Force series.
The 2008 Mazda 6 S Touring uses the 17-inch radial tire size rather than the 18-inch Grand Touring setup. For this trim, the practical choice is comparing the available blackwall performance radial options while confirming that the car has not been changed to a different wheel package.
The 2008 Mazda 6 i also uses the 17-inch radial fitment found on several other sub-models in this range. Tire shopping is therefore straightforward as long as the original wheel diameter is still in place and any aftermarket wheel changes are checked before selecting a replacement.
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.
Best 2008 Mazda 6 Tires for Sale
Available 2008 Mazda 6 tire choices focus on the two factory-size radial fitments, with BFGoodrich blackwall options across several g-Force series. The main points to compare in the product grid are wheel-diameter match, tire series, and the rim-width range tied to each size.
Common 2008 Mazda 6 tire questions usually come down to sub-model size differences, 17-inch versus 18-inch wheel fitment, and how to choose between the available BFGoodrich g-Force radial options. The answers below also cover maintenance and fitment checks before regular road use.
Tire Size & Fitment
What tire size fits a 2008 Mazda 6?
A 2008 Mazda 6 uses either 215/50R17 or 215/45R18, and both are radial tire sizes. The 215/50R17 size fits the Mazda 6 i, S Touring, and S Sport VE, while the 215/45R18 size fits the S Grand Touring.
The key is identifying the exact sub-model or confirming the wheel diameter already on the car. Since the two sizes use different rim diameters, tire selection starts with matching the existing 17-inch or 18-inch wheel setup rather than comparing tread designs first.
What size rim does a 2008 Mazda 6 use?
The 2008 Mazda 6 uses either a 17-inch or 18-inch rim, depending on sub-model. The 215/50R17 tire fits a 17-inch rim, and the 215/45R18 tire fits an 18-inch rim.
Wheel diameter should be confirmed before ordering tires, especially if the car has changed hands or has aftermarket wheels. A quick check of the tire sidewall and the wheel itself helps prevent choosing the wrong size, and wheel width should also be reviewed when comparing product options within the correct diameter.
Do all 2008 Mazda 6 sub-models use the same tire size?
No, the covered 2008 Mazda 6 sub-models do not all use the same tire size. The Mazda 6 i, S Touring, and S Sport VE use 215/50R17, while the S Grand Touring uses 215/45R18.
That difference matters because the two tire sizes are tied to different wheel diameters, not just slightly different proportions. Buyers should verify the exact trim or inspect the car's current wheels before choosing tires, particularly when a vehicle may have received replacement wheels at some point in its life.
Choosing the Right Tire
What should I consider when choosing a 2008 Mazda 6 tire?
Start with the correct size for the exact sub-model, because the 2008 Mazda 6 uses either 215/50R17 or 215/45R18. From there, compare radial tire series, wheel-width compatibility, and any product details that affect how closely the tire matches the car's intended use.
A daily-driven car may call for a different balance than one chosen mainly for sharper road feel or a more aggressive replacement style. It also helps to confirm that the car still has the original wheel diameter, since selecting the wrong size can stop the comparison before tread design or brand differences even matter.
What brands offer tires for the 2008 Mazda 6?
The available tires for the covered 2008 Mazda 6 fitments come from BFGoodrich. Across the two sizes, the lineup includes several g-Force series, giving the buyer more than one way to stay within the correct radial fitment.
Since the brand is consistent here, the real comparison shifts to tire series and size-specific fitment. It makes sense to focus on the correct 17-inch or 18-inch application first, then compare product characteristics such as series type and compatible rim-width range within that exact size.
What tire series are available for the 2008 Mazda 6?
The 2008 Mazda 6 fitments shown here are available in BFGoodrich g-Force series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Series availability depends on whether the car uses the 17-inch or 18-inch tire size.
That means the smartest comparison is made within the exact tire size your Mazda 6 uses, not across both sizes at once. Once the wheel diameter is confirmed, the series differences become easier to evaluate in terms of how you want the car to feel and what type of replacement tire character suits your use.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mazda 6?
A period-style 2008 Mazda 6 still begins with the correct original size format for the exact sub-model, either 215/50R17 or 215/45R18. Since both fitments are modern radial metric sizes, staying with the proper diameter and profile does more for the car's visual balance than chasing an unrelated vintage-style tire look.
Blackwall construction suits the era naturally, and the available BFGoodrich g-Force series keep the presentation in step with the Mazda 6's sport sedan character. For buyers aiming at a highly exact restoration, trim-specific reference material and original vehicle documentation are worth checking before making the final series choice.
Does correct tire fitment matter for a 2008 Mazda 6 restoration?
Yes, correct tire fitment matters on a 2008 Mazda 6 restoration because this model uses two different wheel-and-tire combinations depending on sub-model. The difference between 215/50R17 and 215/45R18 affects both appearance and how accurately the car reflects its intended trim-level setup.
Using the wrong diameter can change the stance and visual proportion even before driving enters the picture. A restoration-minded buyer should confirm sub-model, inspect the wheels currently on the car, and choose a tire that preserves the right size relationship instead of assuming all Mazda 6 trims shared one fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mazda 6?
Yes, modifications can affect tire fitment on a 2008 Mazda 6, especially when the car has aftermarket wheels, suspension changes, or altered ride height. That matters here because the car already has two legitimate factory-size paths tied to different rim diameters.
A modified setup should be checked for actual wheel diameter and width before replacing tires. Clearance at the fender, strut, and steering range is also worth reviewing, since even a correct nominal tire size can create problems when the wheel package or suspension geometry is no longer stock.
What should I inspect before driving a 2008 Mazda 6 on new tires?
Before driving a 2008 Mazda 6 on new tires, inspect the wheel condition, valve stems, and tire pressure, and confirm that the tire size matches the car's 17-inch or 18-inch wheel setup. It also helps to look over alignment-related wear issues that may have affected the old tires.
A short initial drive should be followed by another quick check for air loss, rubbing, or any sign that the tire is not seating or clearing properly. On a car that has sat for a while, examining suspension bushings, shocks, and steering components can prevent a new set of tires from being compromised early.
How often should tires on a 2008 Mazda 6 be inspected?
Tires on a 2008 Mazda 6 should be inspected regularly, not just when tread appears low. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, or cracking deserve attention, especially on a car that may see uneven use or long periods of parking.
Monthly pressure checks are a sensible habit, and a closer inspection before longer trips adds another layer of confidence. Cars that spend more time stored than driven can develop age-related tire issues even without high mileage, so condition matters just as much as tread depth when deciding whether a tire remains roadworthy.
