The 2009 Mazda MX-5 Miata carried forward the lightweight, open-top roadster formula that made the Miata such a distinct modern sports car. Compact dimensions, responsive handling, and an emphasis on driver involvement mean tire choice has a noticeable effect on how the car feels on the road. This model uses radial tires in two primary sizes, 205/50R16 and 205/45R17, depending on sub-model and wheel package. Available choices stay firmly in a modern performance-oriented blackwall presentation, with BFGoodrich options across g-Force series. The key step is matching the tire to the exact trim and wheel diameter before comparing series, load details, and overall road-use priorities.
Which Tire Size Is Right for The 2009 Mazda MX-5 Miata
The 2009 Mazda MX-5 Miata uses two primary tire sizes, and the right one depends on the specific sub-model and its wheel diameter. Sport and SV models use a 16-inch fitment with 205/50R16, while Touring and Grand Touring models use a 17-inch fitment with 205/45R17. Before choosing a tire, confirm the trim level and verify whether the car still has its original wheel setup.
A 205/45R17 tire uses a 205 millimeter section width, a 45-series aspect ratio, radial construction, and fits a 17-inch rim. On the 2009 Mazda MX-5 Miata, this size belongs to sub-models equipped with the larger wheel package and keeps the car in a modern low-profile radial format. Available choices in this size come from BFGoodrich in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This size is the one to evaluate when the car is a Touring or Grand Touring model, or when a 17-inch wheel is already confirmed on the vehicle.
A 205/50R16 tire is 205 millimeters wide, uses a 50-series profile, features radial construction, and mounts on a 16-inch rim. For the 2009 Mazda MX-5 Miata, this size applies to sub-models fitted with the 16-inch wheel setup and maintains a slightly taller sidewall than the 17-inch option. BFGoodrich offers this size in blackwall form through g-Force Sport Comp 2 and g-Force Comp 2 AS series. This is the size to compare when the car is an SV or Sport model, or when the wheel diameter confirms the 16-inch fitment.
Sub-model fitment matters on the 2009 Mazda MX-5 Miata because tire size changes with the wheel package. Identifying whether the car is an SV, Sport, Touring, or Grand Touring model is the first step before comparing tire series or checking wheel specifications.

2009 Mazda MX-5 Miata Grand Touring
The 2009 Mazda MX-5 Miata Grand Touring uses the 205/45R17 radial fitment. That means tire selection starts with the 17-inch wheel setup, then moves to comparing BFGoodrich blackwall options by series and confirming the wheel remains within the intended rim-width range.
The 2009 Mazda MX-5 Miata SV uses the 205/50R16 radial size. Tire selection for this sub-model centers on the 16-inch wheel fitment, with blackwall BFGoodrich choices that can be compared by series and by the actual wheel dimensions on the car.
The 2009 Mazda MX-5 Miata Sport also uses the 205/50R16 radial fitment. For this trim, the main decision is not between multiple primary sizes, but between the available tire series and whether the car still retains the correct 16-inch wheel setup.
The 2009 Mazda MX-5 Miata Touring uses the 205/45R17 radial size. That places the focus on confirming the 17-inch wheel package and then choosing among the available BFGoodrich blackwall tires in the appropriate series for the car's intended use.
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:

Tire Size & Fitment
What tire size fits a 2009 Mazda MX-5 Miata?
A 2009 Mazda MX-5 Miata uses one of two radial tire sizes: 205/50R16 or 205/45R17. The 205/50R16 size applies to Sport and SV models, while Touring and Grand Touring models use 205/45R17. Both are modern metric radial sizes, but they are tied to different wheel diameters and trim-level setups.
The practical step is confirming the exact sub-model and checking the actual wheel diameter on the car before choosing a tire. A Miata that has been fitted with different wheels over time may no longer match its original trim-based setup, so the tire should be selected to match both the intended fitment and the wheel currently installed.
What size rim does a 2009 Mazda MX-5 Miata use?
The 2009 Mazda MX-5 Miata uses either a 16-inch or 17-inch rim, depending on sub-model. Sport and SV models use the 205/50R16 fitment on a 16-inch rim, while Touring and Grand Touring models use the 205/45R17 fitment on a 17-inch rim. Rim diameter is a primary fitment detail on this car.
Checking the wheel itself matters before replacing tires, especially on a car that may have changed hands or been modified. A 16-inch tire cannot be mounted on a 17-inch wheel, and a 17-inch tire cannot be used on a 16-inch wheel, so confirming the wheel size avoids ordering the right width and profile in the wrong diameter.
Do all 2009 Mazda MX-5 Miata sub-models use the same tire size?
No, the 2009 Mazda MX-5 Miata does not use one tire size across every sub-model. Sport and SV models use 205/50R16, while Touring and Grand Touring models use 205/45R17. All of these are radial tires, but the size difference follows the trim's wheel package rather than a single universal fitment.
That means trim identification is important before comparing tire options. It also helps to verify the wheel diameter already on the car, since a Miata with aftermarket wheels or a previous owner change may not still match its original sub-model setup. Tire selection should follow the wheel and trim combination actually present.
Choosing the Right Tire
What should I consider when choosing a 2009 Mazda MX-5 Miata tire?
Start with the correct primary size for the car: 205/50R16 for Sport and SV, or 205/45R17 for Touring and Grand Touring. From there, compare the available BFGoodrich radial options by tire series, blackwall presentation, rim-width compatibility, and load details where they are stated for the specific size.
The right choice depends on matching the tire to the wheel already on the car and to the way the Miata will be used. A roadster like this responds noticeably to tire changes, so it is worth checking the wheel width, reviewing the series differences, and making sure the overall setup suits regular driving rather than choosing by size alone.
What brands offer tires for the 2009 Mazda MX-5 Miata?
BFGoodrich is the brand available in the applicable 205/45R17 and 205/50R16 sizes for the 2009 Mazda MX-5 Miata. Within those sizes, the available product lines include g-Force Comp 2 AS, g-Force Sport Comp 2, and, in the 17-inch fitment, g-Force Phenom T/A. All of these are radial blackwall tires.
Since the brand choice is concentrated here, the more useful comparison is between series and size-specific details rather than between multiple manufacturers. Focus on selecting the correct trim-based size first, then compare each BFGoodrich option by wheel compatibility, load figures where listed, and the kind of road use expected from the car.
What tire series are available for the 2009 Mazda MX-5 Miata?
The available tire series for the 2009 Mazda MX-5 Miata include BFGoodrich g-Force Comp 2 AS and g-Force Sport Comp 2 in both primary sizes. The 205/45R17 fitment also includes BFGoodrich g-Force Phenom T/A. All are modern radial blackwall choices built around the Miata's 16-inch and 17-inch fitments.
Series selection matters once the correct size is confirmed, because it lets you compare closely related tire options within the same brand. The useful next step is checking which series is offered in your exact size, then reviewing the wheel-width range and any stated load information so the tire matches both the wheel and the car's intended use.
Restoration & Appearance
Does correct tire fitment matter for a 2009 Mazda MX-5 Miata restoration?
Yes, correct tire fitment matters on a 2009 Mazda MX-5 Miata restoration because the car uses two distinct modern radial sizes tied to different trims and wheel diameters. A Sport or SV should be evaluated around 205/50R16, while Touring and Grand Touring models should be evaluated around 205/45R17 to keep the wheel-and-tire relationship in the proper range.
Appearance is only part of the equation on a restored Miata. The right size also helps preserve the intended stance and overall presentation without introducing an avoidable mismatch between tire profile and wheel diameter. When originality matters closely, the trim level and actual wheel setup should be confirmed before selecting the final tire.
How does tire construction affect the appearance of a restored 2009 Mazda MX-5 Miata?
Tire construction is straightforward on the 2009 Mazda MX-5 Miata because the primary fitments are radial rather than bias-ply. That means the restored look of the car is shaped more by using the correct modern metric size and wheel diameter than by choosing between vintage construction types. The available tires also keep a clean blackwall presentation.
For a restoration-oriented owner, the visual result comes from staying with the proper 16-inch or 17-inch fitment for the trim and avoiding an off-profile substitute that changes the car's stance. This is a later collector vehicle, so maintaining the intended modern roadster look usually starts with the correct radial size rather than period-style sidewall details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Mazda MX-5 Miata?
Yes, modifications can affect tire fitment on a 2009 Mazda MX-5 Miata. If the car has aftermarket wheels, suspension changes, lowering, or body alterations, the original 205/50R16 or 205/45R17 fitment may no longer be the only factor. Wheel diameter, wheel width, and available clearance all become part of the decision.
A Miata is sensitive to changes in wheel and tire setup, so even a correct nominal tire size should be checked against the actual car. Inspect steering clearance, fender clearance, and wheel dimensions before installation. That extra step is especially important when the car no longer retains its original trim-based wheel package.
What should I inspect before driving a 2009 Mazda MX-5 Miata on new tires?
Before driving a 2009 Mazda MX-5 Miata on new tires, confirm that the tire size matches the trim and wheel diameter, then inspect overall installation condition. Check air pressure, bead seating, valve stems, and visible clearance around the fenders and suspension. It also helps to verify that all four tires match the intended setup.
Road-use inspection should continue after installation with a short initial drive and a second look for rubbing, uneven clearance, or air loss. On a lightweight sports car, proper inflation and clean fitment have a noticeable effect on steering feel and stability, so a quick post-install check is worth doing before regular driving.
How should tires on a collector 2009 Mazda MX-5 Miata be maintained?
Tires on a collector 2009 Mazda MX-5 Miata should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Look for cracking, cuts, bulges, uneven wear, or slow air loss, even if the car is driven infrequently. Low-mileage collector use does not prevent rubber from aging over time.
Storage conditions matter as much as mileage on a lightly used roadster. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires between drives. It is also wise to inspect the tires before any longer trip, since a car that sits often can develop issues that are easy to miss.
