The 2008 Saturn Aura came from Saturn’s final full push into the midsize sedan market, offering a more substantial, European-influenced feel than the brand’s earlier compact cars. It appeals to owners who want a modern GM-era sedan with clean styling and trim-level variety that can still be driven regularly. Tire fitment on the 2008 Saturn Aura is fully radial, but it is not one-size-fits-all, with 16-inch, 17-inch, and 18-inch applications tied to specific sub-models. That makes wheel diameter the first thing to confirm, followed by the exact trim. Once that is settled, the decision shifts to comparing available radial tire choices for road use, appearance, and overall setup.
Which Tire Size Is Right for The 2008 Saturn Aura
The 2008 Saturn Aura uses three primary tire sizes, and the correct one depends on the sub-model and wheel diameter. Green Line models use a 16-inch fitment, XE and XE V6 models use a 17-inch fitment, and XR models use an 18-inch fitment. Before choosing a tire, confirm the exact trim and verify the car still has its intended wheel size, especially if it has seen aftermarket wheel changes.
215/60R16 is a metric radial size in which 215 identifies the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. On the 2008 Saturn Aura, this size belongs to the Green Line application and reflects a fully modern radial fitment rather than a vintage sizing system. It is the most comfort-oriented size used on this model line, with its own wheel diameter requirement. Choose it only after confirming the Green Line trim and checking that the car is still running the proper 16-inch wheels.
225/50R17 is a metric radial size with a 225-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 17-inch rim diameter. This size is used on 2008 Saturn Aura XE and XE V6 models, so it is tied to those sub-models rather than the full Aura range. Available choices include BFGoodrich and Nitto products, all in blackwall form, across g-Force and NT555 G2 series. It is the size to evaluate when the car has the correct 17-inch wheels and the owner wants to compare brand, series, rim-width compatibility, load specification, and tire character within the proper fitment.
225/50R18 follows the same modern metric radial format, with 225 for nominal width in millimeters, 50 for aspect ratio, R for radial construction, and 18 for wheel diameter. On the 2008 Saturn Aura, this size is associated with the XR, making wheel confirmation especially important before any selection is made. Product choices in this size center on BFGoodrich blackwall radials across several g-Force series, including all-season and more performance-oriented options. It is the right fitment to consider when the car retains its 18-inch setup and the goal is to compare tire series and specifications within the proper XR application.
Tire fitment on the 2008 Saturn Aura varies by sub-model, so trim identification matters before anything else. The Green Line, XE, XE V6, and XR do not all share the same wheel and tire package, making it important to confirm both the badge and the actual wheel diameter on the car.

2008 Saturn Aura Green Line
The 2008 Saturn Aura Green Line uses its own 16-inch radial tire fitment, separate from the larger-wheel XE and XR applications. That makes wheel-size confirmation especially important if the car has been changed from its original setup or is wearing replacement wheels.
The 2008 Saturn Aura XE uses the 17-inch radial fitment shared with the XE V6. Tire selection here centers less on finding the right size family and more on comparing the available blackwall radial choices within the proper 17-inch application.
The 2008 Saturn Aura XE V6 shares the same 17-inch radial tire size used by the XE. That makes the main selection question one of tire series, brand, and wheel compatibility rather than sorting through multiple primary sizes for this specific trim.
The 2008 Saturn Aura XR uses the 18-inch radial fitment, which sets it apart from the other Aura sub-models. Tire choice begins with confirming the XR still has the proper 18-inch wheels, then comparing the available blackwall radial options within that 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.

These FAQs focus on 2008 Saturn Aura tire sizing by sub-model, wheel-diameter differences, available radial choices, and the fitment checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2008 Saturn Aura?
The 2008 Saturn Aura uses three different tire sizes depending on sub-model: 215/60R16, 225/50R17, and 225/50R18. Green Line models use 215/60R16, XE and XE V6 models use 225/50R17, and XR models use 225/50R18.
That means the first step is identifying the exact trim and confirming the wheel diameter currently on the car. A used Aura may no longer have its original wheels, so the size on the sidewall and the actual wheel size should both be checked before choosing a replacement tire.
What size rim does a 2008 Saturn Aura use?
A 2008 Saturn Aura can use 16-inch, 17-inch, or 18-inch rims, depending on the sub-model. The Green Line uses a 16-inch fitment, XE and XE V6 use 17-inch fitments, and the XR uses an 18-inch fitment.
Rim diameter is the key fitment checkpoint on this vehicle because the three primary tire sizes are tied directly to different wheel sizes. Before replacing tires, inspect the wheel itself or confirm the size already mounted, especially if the car has aftermarket wheels or a previous owner changed the original setup.
Why does the 2008 Saturn Aura have more than one tire size?
The 2008 Saturn Aura has more than one tire size because different sub-models were equipped with different wheel diameters. The Green Line, XE, XE V6, and XR do not all share the same wheel-and-tire package, so their tire sizes differ accordingly.
That variation means there is no single universal Aura tire size for 2008. Trim level and wheel size have to be matched first, then the owner can compare tires within the correct size for that setup. This matters most on used cars, where wheel swaps can make the current fitment different from the original sub-model application.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Saturn Aura?
Start with the correct tire size for the exact 2008 Saturn Aura sub-model and wheel diameter. After that, compare radial construction details such as tire series, brand, rim-width compatibility, load specification where given, and whether the tire’s character suits everyday driving or a more performance-oriented feel.
A Green Line owner should focus first on staying with the proper 16-inch fitment, while XE, XE V6, and XR owners can compare the available 17-inch or 18-inch options more closely. It also helps to check whether the car is stock or modified, since wheel changes can matter as much as the trim badge.
What sidewall styles are available for 2008 Saturn Aura tires?
The available 2008 Saturn Aura tire options shown here use blackwall sidewalls. That applies to the listed 225/50R17 and 225/50R18 product choices, including BFGoodrich and Nitto offerings in those sizes.
Since the visible choices stay within one sidewall style, the selection process shifts toward tire series, brand, load specification, and wheel-width compatibility rather than appearance-driven sidewall differences. Buyers who want to keep the car looking clean and contemporary will likely find that a blackwall presentation matches the Aura’s modern sedan character well.
What brands offer tires for the 2008 Saturn Aura?
BFGoodrich and Nitto both offer tire options for the 2008 Saturn Aura sizes shown here. The 225/50R17 fitment includes BFGoodrich and Nitto choices, while the 225/50R18 fitment shown here centers on BFGoodrich options across several g-Force series.
Brand is only one part of the decision, so it should be weighed alongside the correct trim-level fitment and wheel diameter. Once the proper size is confirmed, compare each tire’s series, load information where stated, and rim-width range to make sure the choice matches the car’s setup and intended use.
Restoration & Appearance
Does correct tire fitment matter for a 2008 Saturn Aura restoration?
Correct tire fitment still matters on a 2008 Saturn Aura, even though it is a more modern vehicle than a traditional collector car. The right size helps preserve the intended relationship between the body, wheel opening, and wheel diameter used on the Green Line, XE, XE V6, or XR.
A restoration-minded owner should begin by confirming the trim and making sure the car has the proper wheel size before selecting tires. Keeping the fitment aligned with the original sub-model layout usually produces a cleaner, more coherent appearance than mixing wheel diameters or substituting a different size without checking proportions and clearance.
How does tire construction affect the appearance of a restored 2008 Saturn Aura?
On a 2008 Saturn Aura, tire construction is straightforward because the primary fitments are all radial. That means the visible appearance difference is less about bias-ply versus radial and more about maintaining the correct size, wheel diameter, and sidewall profile for the specific sub-model.
A restoration-oriented result comes from matching the Green Line, XE, XE V6, or XR with its proper fitment rather than forcing a different wheel-and-tire package. Even on a newer sedan, an incorrect tire size can change the stance and visual balance, so the best appearance usually starts with stock-style sizing discipline.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Saturn Aura?
Yes, modifications can affect tire fitment on a 2008 Saturn Aura. Aftermarket wheels, suspension changes, lowering, or body alterations can change the wheel diameter, width, or clearance conditions that the original 215/60R16, 225/50R17, or 225/50R18 fitments were based around.
That is why the current setup should be checked before ordering replacement tires. Wheel size stamped on the rim, actual tire size on the sidewall, and visible clearance at the fender and steering components all matter. A modified Aura should be evaluated by its present hardware, not only by its original sub-model designation.
What should I inspect before driving a 2008 Saturn Aura on new tires?
Before driving a 2008 Saturn Aura on new tires, inspect the wheels for the correct diameter and obvious damage, then verify the tires are the right size for the sub-model. It also helps to check inflation pressure, valve stems, lug torque, and basic clearance at full steering lock.
A quick inspection of suspension and steering condition is worthwhile on any used midsize sedan, especially if the car has uneven tire wear or has been sitting. Fresh tires cannot compensate for worn components, poor alignment, or bent wheels, so a road-ready setup depends on the whole assembly working together properly.
How often should tires on a 2008 Saturn Aura be inspected?
Tires on a 2008 Saturn Aura should be inspected regularly, not only when tread looks low. A visual check for uneven wear, cracking, bulges, cuts, and air loss is sensible throughout the driving season, especially on a car that may see mixed daily use and longer highway trips.
Cars that spend time parked can develop age-related tire issues even if mileage stays modest. It is smart to check pressure and condition before longer drives, and to look more closely whenever steering feel changes or vibration appears. Regular inspections help catch fitment, wear, or aging problems before they become more serious.
