The 2009 Saturn Aura came from the final stretch of Saturn’s midsize sedan era, blending clean contemporary styling with a more substantial road feel than many buyers expected from the brand. It remains a practical modern collectible for owners who appreciate late-2000s GM design without stepping into a full-size sedan. Tire fitment on the 2009 Saturn Aura centers on three radial sizes: 215/55R17, 225/50R17, and 225/50R18, with sub-model and wheel package determining which one belongs on the car. Available choices lean toward blackwall performance-oriented radial lines from BFGoodrich and Nitto. The key is confirming the exact trim and wheel diameter before comparing tread series, load specifications, and overall driving intent.
Which Tire Size Is Right for The 2009 Saturn Aura
The 2009 Saturn Aura uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Two sizes fit 17-inch wheels, while one fits an 18-inch wheel, so confirming both the trim level and the actual wheel on the car should come first. Once that is settled, the decision becomes choosing the right radial tire series and specification for the way the car is driven.
215/55R17 is a metric radial size in which 215 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2009 Saturn Aura, this size is one of the main 17-inch fitments and appears across several sub-model applications. Current choices in this size come from BFGoodrich in blackwall form, including g-Force Comp 2 AS and g-Force Phenom T/A lines. This size is the one to evaluate when the car is equipped with the applicable 17-inch setup and the goal is to stay with the proper overall fitment format.
225/50R17 is also a metric radial size, with a 225-millimeter section width, a 50-series profile, and a 17-inch rim diameter. For the 2009 Saturn Aura, it serves specific 17-inch applications rather than every version of the car, so it should be matched to the correct trim and wheel package. Available products include blackwall options from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2 series. It is the size to compare when the car carries the applicable 17-inch wheel and a slightly wider fitment than 215/55R17.
225/50R18 uses the same basic metric radial format, with 225 indicating section width in millimeters, 50 indicating aspect ratio, and 18 identifying the rim diameter. On the 2009 Saturn Aura, this size belongs to the 18-inch application, making wheel diameter the first checkpoint before anything else. BFGoodrich offers blackwall choices in this size through the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the fitment to consider when the car has the factory-style 18-inch wheel setup and the buyer wants to compare series character within the correct size.
Tire fitment for the 2009 Saturn Aura is not the same across every sub-model. Checking the exact trim matters because the Aura lineup uses more than one radial size, and the XR range spans more than one 17-inch fitment while the XR V6 moves to an 18-inch application.

2009 Saturn Aura Hybrid
The 2009 Saturn Aura Hybrid uses a 215/55R17 radial fitment on a 17-inch wheel. That keeps the selection process fairly straightforward, with the main decision shifting to tire series and product specifications rather than choosing between multiple primary sizes.
The 2009 Saturn Aura XE also uses the 215/55R17 radial size. For an XE, the focus is less about size identification and more about confirming the existing wheel setup before comparing available blackwall radial choices in that fitment.
The 2009 Saturn Aura XR can use either 215/55R17 or 225/50R17, both in radial construction on 17-inch wheels. That makes exact wheel and trim verification especially important before selecting a tire, since both sizes share the same rim diameter but are not the same fitment.
The 2009 Saturn Aura XR V6 uses 225/50R18 radial tires on an 18-inch wheel. For this sub-model, the key is confirming that the car still carries the proper 18-inch wheel setup before comparing tire series and load-related specifications within the correct size.
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 2009 Saturn Aura Tires for Sale
Available 2009 Saturn Aura tires center on 17-inch and 18-inch radial fitments from BFGoodrich and Nitto. The product grid is mainly a comparison of blackwall performance-oriented series, with differences in tire line, rim-width compatibility, load figures where stated, and size-specific application.
Owners researching 2009 Saturn Aura tires usually need to confirm the exact sub-model, wheel diameter, and correct metric radial size before comparing brands or tire series. The questions below focus on fitment, product selection, and practical checks before regular road use.
Tire Size & Fitment
What tire size fits a 2009 Saturn Aura?
The 2009 Saturn Aura uses three primary radial tire sizes: 215/55R17, 225/50R17, and 225/50R18. The correct one depends on the exact sub-model and wheel package, rather than the model name alone. Hybrid and XE applications use 215/55R17, XR uses either 215/55R17 or 225/50R17, and XR V6 uses 225/50R18.
The practical first step is to confirm both the trim and the actual wheel diameter on the car. An XR can create confusion because it uses two different 17-inch sizes, while the XR V6 moves to an 18-inch wheel. If the car has had wheels changed at some point, match the tire size to the wheel and vehicle clearance rather than assuming every Aura uses the same setup.
What size rim does a 2009 Saturn Aura use?
A 2009 Saturn Aura uses either a 17-inch or 18-inch rim, depending on sub-model and tire size. The 215/55R17 and 225/50R17 fitments use 17-inch wheels, while 225/50R18 uses an 18-inch wheel. That makes rim diameter one of the most important fitment checkpoints on this car.
Wheel diameter should be confirmed before comparing tire lines, because a 17-inch tire and an 18-inch tire are not interchangeable even if the widths look similar on paper. The next step is checking the wheel width against the tire’s acceptable range, especially if the car has aftermarket wheels. A correct diameter alone is not enough to guarantee the tire is the right match for the wheel and vehicle setup.
Do all 2009 Saturn Aura sub-models use the same tire size?
No, 2009 Saturn Aura sub-models do not all use the same tire size. The Hybrid and XE use 215/55R17, the XR can use either 215/55R17 or 225/50R17, and the XR V6 uses 225/50R18. Every application is radial, but the size and sometimes the wheel diameter change across the lineup.
That variation matters because the wrong size can affect wheel fit, overall dimensions, and clearance. The XR is the trim most likely to require a closer look, since two different 17-inch fitments appear under that badge. Reading the sidewall on the existing tire and verifying the wheel diameter gives a clearer starting point than choosing by model name alone, especially on a car that may have had past wheel or tire changes.
Choosing the Right Tire
What should I consider when choosing a 2009 Saturn Aura tire?
Start with the correct primary size for the exact 2009 Saturn Aura sub-model and wheel diameter: 215/55R17, 225/50R17, or 225/50R18. From there, compare radial tire series, rim-width compatibility, and load specifications where they are stated. Because the Aura uses more than one fitment, getting the size right matters before comparing brand or tread character.
Once size is confirmed, think about how the car is actually used. A daily-driven Aura may call for one kind of radial personality, while a weekend car may lead the owner toward a different series within the same size. It also helps to check whether the car still has stock wheels, since aftermarket width changes can narrow the list of suitable tires even when the diameter appears correct.
What brands offer tires for the 2009 Saturn Aura?
BFGoodrich and Nitto offer tires for 2009 Saturn Aura fitments in the sizes covered here. BFGoodrich appears across all three primary sizes, while Nitto is available in 225/50R17. Those options keep the focus on modern radial performance-oriented products rather than broad appearance variations.
Brand choice should come after fitment is nailed down, not before. A BFGoodrich option may be available in all Aura sizes, but the exact series still changes by application, and Nitto appears only in one of the 17-inch fitments. Comparing the tire line, wheel-width range, and any stated load figure is usually more useful than choosing solely by brand name when narrowing the right tire for the car.
What tire series are available for the 2009 Saturn Aura?
The 2009 Saturn Aura tire selection here includes BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2, depending on size. Not every series appears in every fitment, so the exact size determines which product families are actually in play.
That means the best comparison is made inside the correct size rather than across the whole Aura range. A 215/55R17 buyer is choosing from a smaller group than someone shopping 225/50R17 or 225/50R18. Once the size is settled, the series names help distinguish the available tire personalities and specifications without drifting into a tire that belongs on a different wheel diameter or sub-model.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Saturn Aura?
A period-style 2009 Saturn Aura tire choice starts with the exact original-size format used on the car’s sub-model: 215/55R17, 225/50R17, or 225/50R18, all in radial construction. Since the available products here are modern blackwall radials, the visual presentation stays close to the understated look many late-2000s midsize sedans carried on the road.
Appearance should be balanced with fitment discipline. Matching the correct size and wheel diameter preserves the car’s stance more faithfully than forcing a different profile for looks alone. Owners pursuing a very exact restoration-style result should compare the current wheel-and-tire setup to original vehicle literature or marque-specific references, especially if the Aura has changed hands several times or received aftermarket wheels.
Does correct tire fitment matter for a 2009 Saturn Aura restoration?
Yes, correct tire fitment matters on a 2009 Saturn Aura restoration because the car uses more than one size and more than one wheel diameter across the model range. Staying with the proper 17-inch or 18-inch application helps keep the car’s proportions, ride height, and overall presentation aligned with its intended configuration.
The biggest risk is assuming any Aura tire will work on any Aura. An XR can use two different 17-inch sizes, while the XR V6 uses an 18-inch setup, so trim identification and wheel verification are essential. Even on a later collector vehicle like this one, correct fitment supports both appearance and usability better than choosing a tire only because it seems close in width or profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Saturn Aura?
Yes, modifications can affect tire fitment on a 2009 Saturn Aura even when the tire size looks close to stock. Aftermarket wheels, changes in wheel width, suspension lowering, or body alterations can change clearance at the fender, strut, or steering range. That matters on a car with multiple factory-size combinations and both 17-inch and 18-inch applications.
The safest approach is to verify the actual wheel diameter and width already on the car, then compare them with the tire’s fitment range before choosing a replacement. Steering clearance should also be checked lock to lock if the Aura has been modified. A car that has stayed stock is easier to match, while a changed setup calls for more careful measurement before mounting a new set.
What should I inspect before driving a 2009 Saturn Aura on new tires?
Before driving a 2009 Saturn Aura on new tires, inspect the wheels for damage, confirm the tire size matches the car’s wheel diameter, and make sure inflation is set correctly for the application. It is also wise to check for suspension wear, alignment issues, and any signs of rubbing that might have developed with the previous tires.
A quick road-use inspection should include tread seating, valve condition, and any vibration once the car is back on the road. The Aura’s multiple fitments make it especially important to confirm that the installed tire is the intended one for the trim and wheel package. Catching a mismatch early is easier than chasing uneven wear or clearance problems after several hundred miles.
How often should tires on a 2009 Saturn Aura be inspected?
Tires on a 2009 Saturn Aura should be inspected regularly, not only at replacement time. Monthly pressure checks, periodic tread and sidewall inspection, and a close look before longer trips are sensible habits, especially on a car that may alternate between commuter duty and longer periods of sitting. Regular attention helps catch air loss, irregular wear, cracking, or impact damage early.
Inspection should also follow the way the car is used. A low-mileage Aura that sits for extended periods can age its tires differently than one that is driven every week. Looking at wear patterns can also reveal whether the car needs alignment or suspension attention. For a model with several valid sizes, the inspection routine is a good time to confirm the current tires still match the wheel and trim setup.
