The 2007 Saturn Aura arrived as Saturn’s midsize sedan with a more polished, mainstream feel than the brand’s earlier compact cars, giving buyers a family car that could lean toward efficiency, everyday comfort, or a slightly sportier character depending on trim. Tire fitment follows that split closely, with the 2007 Saturn Aura using three different radial sizes: 215/60R16, 225/50R17, and 225/50R18. That makes the first decision less about tire construction and more about identifying the exact sub-model and wheel diameter. From there, the choice comes down to the right metric size, available blackwall performance-oriented tire lines, and making sure the car still wears the wheel setup intended for that trim.
Which Tire Size Is Right for The 2007 Saturn Aura
The 2007 Saturn Aura uses three primary tire sizes, and each one is tied to a specific sub-model and wheel diameter. All three are radial metric sizes, but the correct choice depends on confirming whether the car is a Green Line, XE, or XR and then matching the tire to the 16-inch, 17-inch, or 18-inch wheel on the car.
215/60R16 is a modern metric radial size. The 215 identifies nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2007 Saturn Aura, this size supports the trim that uses a 16-inch wheel and keeps the fitment in the same modern radial format as the rest of the lineup. For an Aura wearing this size, the key step is matching the tire to the correct sub-model and wheel diameter before comparing tread style, ride priorities, or any replacement-brand options.
225/50R17 is a metric radial size with a 225-millimeter nominal section width, a 50-series profile, and a 17-inch rim diameter. On the 2007 Saturn Aura, this size belongs to the trim that uses a 17-inch wheel, so it should be selected only after confirming the car’s exact setup. Available choices in this size include BFGoodrich and Nitto products in blackwall form, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. That gives owners room to compare brand character, tire series, and rim-width suitability within the correct fitment.
225/50R18 uses the same 225-millimeter nominal width and 50-series profile concept as the 17-inch version, but it is built for an 18-inch wheel. For the 2007 Saturn Aura, that makes wheel diameter confirmation essential, since a 225/50R18 is not the same fitment decision as a 225/50R17 despite the shared width and profile notation. Product choices in this size include BFGoodrich blackwall radial tires across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This size suits owners who need to stay with the 18-inch trim-specific fitment while comparing available series and wheel-width compatibility.
Tire fitment on the 2007 Saturn Aura varies by sub-model, so confirming the exact trim is the first step before choosing a replacement tire. The Green Line, XE, and XR each use a different radial size tied to a different wheel diameter.

2007 Saturn Aura Green Line
The 2007 Saturn Aura Green Line uses its own radial tire fitment on a 16-inch wheel, separate from the larger-wheel Aura trims. For this sub-model, the focus is on keeping the correct metric size and confirming that the car has not been changed to a different wheel package over time.
The 2007 Saturn Aura XE uses the 17-inch-wheel tire fitment, which places it between the Green Line and XR in wheel diameter. That makes tire selection straightforward once the XE trim and wheel size are confirmed, with room to compare available blackwall radial options by brand and series.
The 2007 Saturn Aura XR uses the 18-inch-wheel tire fitment, making it the largest primary tire size in the Aura range for this year. Tire selection should stay centered on the XR’s wheel diameter first, then on comparing available radial tire series that match the car’s intended use and current wheel setup.
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 2007 Saturn Aura Tires for Sale
Available 2007 Saturn Aura product choices center on the 225/50R17 and 225/50R18 sizes, with blackwall radial options from BFGoodrich and Nitto. The main differences are tire series, rim-width compatibility, load figures where stated, and whether the car uses the 17-inch XE or 18-inch XR fitment.
These 2007 Saturn Aura tire FAQs focus on the trim-specific size differences, wheel diameter, radial fitment, available product choices, and the checks that matter before putting the car back into regular road use.
Tire Size & Fitment
What tire size fits a 2007 Saturn Aura?
The 2007 Saturn Aura uses three tire sizes, and the correct one depends on the sub-model. The Green Line uses 215/60R16, the XE uses 225/50R17, and the XR uses 225/50R18. All three are radial metric sizes, so the main fitment difference is not construction type but trim-specific wheel diameter and tire dimensions.
Choosing the right size starts with confirming the exact Aura trim and the wheel diameter currently on the car. A used Aura may have had wheels changed over time, so it is smart to verify both the sub-model and the actual wheel before replacing tires. That prevents ordering a tire that matches the nameplate but not the car’s present setup.
What size rim does a 2007 Saturn Aura use?
A 2007 Saturn Aura can use a 16-inch, 17-inch, or 18-inch rim depending on sub-model. The Green Line uses a 16-inch rim, the XE uses a 17-inch rim, and the XR uses an 18-inch rim. Those rim diameters correspond directly to the primary tire sizes used on each version of the Aura.
Rim diameter should be confirmed before anything else because the 16-inch, 17-inch, and 18-inch tires are not interchangeable choices. Looking at the wheel itself, the current tire sidewall, and the vehicle’s exact trim helps avoid a mismatch. On a car that has been modified, the wheel on the vehicle matters more than assuming the original trim still has its original wheels.
Do all 2007 Saturn Aura sub-models use the same tire size?
No. The 2007 Saturn Aura does not use one shared tire size across all sub-models. The Green Line, XE, and XR each have their own radial tire size, and each one is paired with a different rim diameter. That means tire replacement on this car is trim-specific rather than a one-size-fits-all decision.
This matters because two Aura models parked side by side may need different tires even though they share the same year and model name. The easiest way to narrow it down is to identify the trim and confirm the existing tire size on the sidewall. That extra step keeps the replacement choice aligned with the wheel diameter and intended fitment for the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Saturn Aura?
Start with the exact tire size that matches the car’s sub-model and wheel diameter, since the 2007 Saturn Aura uses three different radial sizes. After size is confirmed, compare tire series, rim-width compatibility, and any stated load figures that apply to the products available for that size. Those details help separate one replacement choice from another.
The next step is to match the tire to how the car is used. An Aura driven mainly for everyday road use may lead to a different product choice than one kept as a cleaner weekend sedan. It also helps to confirm that all four wheels match, especially on a used car, so the selected tire size and series suit the vehicle’s actual setup.
What sidewall styles are available for 2007 Saturn Aura tires?
The available 225/50R17 and 225/50R18 product choices for the 2007 Saturn Aura use a blackwall sidewall style. That gives the car a clean modern appearance that fits the Aura’s original-era sedan character without introducing raised white letters, whitewalls, or other more specialized vintage-style sidewall treatments.
Sidewall style may seem secondary, but it still shapes the car’s finished look. On this Aura, the product differences are driven more by tire series and brand than by sidewall presentation, since the visible style remains blackwall. Once the correct size is confirmed, the practical comparison becomes tread category, wheel compatibility, and the overall look you want the sedan to maintain.
What brands offer tires for the 2007 Saturn Aura?
For the 2007 Saturn Aura sizes with current product choices shown here, tires are available from BFGoodrich and Nitto. The 225/50R17 size includes BFGoodrich and Nitto options, while the 225/50R18 size includes BFGoodrich options. Within those brands, the available selections are blackwall radial tires in several different series.
Brand is only one part of the decision, so it helps to compare each product within the correct size rather than choosing by name alone. Looking at the tire series, wheel-width range, and any stated load information will tell you more about how each option fits your needs. The right comparison starts after the Aura’s exact trim and wheel diameter are confirmed.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Saturn Aura?
A period-style approach for a 2007 Saturn Aura starts with keeping the trim-specific size and wheel diameter intact. That means 215/60R16 for the Green Line, 225/50R17 for the XE, or 225/50R18 for the XR. Because this Aura uses modern radial metric sizing, a period-appropriate look usually comes from preserving the correct overall fitment rather than chasing a vintage-style construction or sidewall treatment.
Blackwall tires fit that restrained factory-era appearance well, especially on a midsize sedan from the late 2000s. Tire series still matter, but the most important appearance decision is avoiding a size that looks out of place on the car. Owners pursuing a more exact restoration-style presentation should compare current fitment against original vehicle literature, window sticker details, or marque-specific references.
Does correct tire fitment matter for a 2007 Saturn Aura restoration?
Yes. Correct tire fitment matters on a 2007 Saturn Aura restoration because each sub-model used a different size and wheel diameter. Staying with the proper trim-specific tire keeps the car’s stance, wheel-to-tire proportion, and overall presentation closer to the way that version of the Aura was intended to appear on the road.
Fitment also affects more than looks. A mismatched diameter or profile can change fender fill, alter the visual balance of the car, and complicate replacement planning later. For a restoration-oriented project, verify the actual trim, check the wheel diameter, and make sure all four tires match before selecting a replacement set. That creates a cleaner result than mixing sizes or guessing from the model name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Saturn Aura?
Yes. Modifications can change tire fitment on a 2007 Saturn Aura even when the original trim is known. Aftermarket wheels, suspension changes, altered ride height, and body modifications can all affect which tire size clears properly. That is especially important on this car because the Aura already spans 16-inch, 17-inch, and 18-inch factory wheel diameters depending on sub-model.
An Aura that has been changed from its original wheel package should be checked by its actual wheel diameter and width, not by trim name alone. Clearance at the fender, suspension, and steering range should also be reviewed before choosing a replacement. That extra inspection helps prevent rubbing issues and keeps the selected tire closer to the dimensions the modified car can actually accommodate.
What should I inspect before driving a 2007 Saturn Aura on new tires?
Before driving a 2007 Saturn Aura on new tires, inspect the wheels for damage, confirm that the new tires match the correct size for the trim, and make sure inflation is set properly for the vehicle’s needs. It is also smart to check alignment condition, valve stems, and the general condition of suspension and steering components.
A short road test should follow installation so any vibration, pull, or clearance issue can be caught early. Looking over the tread after the first few drives can reveal uneven contact if the car needs alignment work. On a sedan like the Aura, good basic checks before regular use help the new tires wear more evenly and support stable everyday driving behavior.
How often should tires on a 2007 Saturn Aura be inspected?
Tires on a 2007 Saturn Aura should be inspected regularly, not just when replacement time comes around. A visual check for uneven wear, low pressure, cuts, bulges, cracking, and embedded debris is worthwhile every month and before longer drives. That routine matters whether the car is a daily driver or a lower-mileage sedan used more occasionally.
Frequent inspection helps catch issues before they turn into vibration, poor wear, or roadside trouble. Tire pressure should be kept consistent, and any recurring air loss deserves attention right away. It also helps to recheck tread condition across all four corners, since uneven wear can point to alignment or suspension concerns. Staying ahead of those problems protects both tire life and road manners.
