The 2008 Saab 9-5 comes from the final stretch of Saab’s long-running midsize sport sedan, a car known for combining understated Swedish design with turbocharged character and everyday practicality. Buyers looking after one today are usually balancing road manners, appearance, and proper fitment rather than chasing a vintage-style bias-ply setup. This exact 2008 Saab 9-5 fitment centers on a 235/45R17 radial tire on a 17-inch rim. Available choices stay within that modern metric size while varying by brand and tire series, including BFGoodrich and Nitto blackwall options. The key is selecting the right 17-inch radial for the car’s actual wheel setup and intended use.
Which Tire Size Is Right for The 2008 Saab 9-5
The 2008 Saab 9-5 uses one primary tire size: 235/45R17. It is a radial fitment on a 17-inch rim, and it is shared across the covered 2.3t and Aero sub-models. That means the main decision is not which factory size applies, but which tire within that size best matches the car’s wheel width, driving use, and preferred brand or tire series.
A 235/45R17 size identifies a radial tire that is 235 millimeters wide, uses a 45-series aspect ratio, and mounts on a 17-inch wheel. On the 2008 Saab 9-5, this is the core modern fitment, so the focus shifts from decoding an older sizing system to choosing the right radial for the car’s intended street use. Available options include BFGoodrich and Nitto blackwall tires across different series such as g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2. This size is the correct starting point when the car retains its 17-inch wheel setup.
Tire fitment is straightforward across the covered 2008 Saab 9-5 sub-models, because both use the same primary size. Checking the exact sub-model still helps confirm that the car has not been changed from its expected 17-inch wheel and radial-tire setup.

2008 Saab 9-5 2.3t
The 2008 Saab 9-5 2.3t uses the same 235/45R17 radial tire size as the other covered sub-model. Tire selection comes down to choosing the right blackwall radial within that size and confirming that the car still has the correct 17-inch wheel arrangement.
The 2008 Saab 9-5 Aero also uses the 235/45R17 radial size, so fitment stays consistent at the sub-model level. The real choice is between the available tire series and brands in that size, along with a quick check that the wheel setup has not been altered.
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.

Common questions for the 2008 Saab 9-5 usually focus on the 235/45R17 fitment, 17-inch wheel compatibility, available radial choices, and what to inspect before putting a turbo-era Saab back into regular road use.
Tire Size & Fitment
What tire size fits a 2008 Saab 9-5?
The 2008 Saab 9-5 uses a 235/45R17 tire size. This is a modern radial fitment mounted on a 17-inch rim, and it applies to the covered 2.3t and Aero sub-models.
That makes size selection fairly simple as long as the car still has its expected wheel setup. A quick check of the wheel diameter, actual wheel width, and any past wheel or suspension changes is still worthwhile before choosing among the available 235/45R17 tires.
What size rim does a 2008 Saab 9-5 use?
The primary tire fitment for the 2008 Saab 9-5 is built around a 17-inch rim. The 235/45R17 tire size confirms that wheel diameter directly, since the final number in the size code is the rim diameter in inches.
Wheel diameter is only part of the fitment picture, so it helps to confirm the wheel width as well before selecting a tire. Available 235/45R17 products in this application are intended for rims within a defined width range rather than every 17-inch wheel.
Do all 2008 Saab 9-5 sub-models use the same tire size?
The covered 2008 Saab 9-5 sub-models share the same tire size. Both the 2.3t and Aero use a 235/45R17 radial tire on a 17-inch rim.
Shared sizing makes replacement easier, but it is still smart to inspect the car before ordering tires. A previous owner may have changed wheels, altered ride height, or fitted a different tire size, and those changes can affect clearance and the range of suitable tire choices.
Choosing the Right Tire
What should I consider when choosing a 235/45R17 tire for a 2008 Saab 9-5?
Start with the correct size, which is 235/45R17, and then compare construction, brand, tire series, and wheel-width compatibility. The available choices for this Saab are radial blackwall tires from BFGoodrich and Nitto, with series that include g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2.
The right choice depends on how the car is used and how closely the wheel setup matches the tire’s approved rim-width range. It also helps to compare specification details such as load information and tire weight, especially on a sedan that may see highway use as well as occasional spirited driving.
What sidewall styles are available for 2008 Saab 9-5 tires?
The available tires for the 2008 Saab 9-5 in 235/45R17 use a blackwall sidewall style. That keeps the look clean and contemporary, which suits the late-production 9-5’s understated sport-sedan character.
Since the sidewall treatment does not vary here, the visual choice is really between tire brands and series rather than between whitewall, redline, or other period-oriented looks. Buyers can focus more closely on fitment details, intended road use, and the tread and specification differences between the available radial options.
What brands offer tires for the 2008 Saab 9-5?
BFGoodrich and Nitto both offer 235/45R17 tires for the 2008 Saab 9-5. Within those brands, the available series include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, and Nitto NT555 G2.
Brand alone should not be the only deciding factor. It is more useful to compare the individual tire series, confirm the wheel-width fitment for the car’s 17-inch wheels, and decide whether the Saab is being set up for regular street driving, broader seasonal use, or a more performance-oriented feel.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Saab 9-5?
A period-appropriate starting point for a 2008 Saab 9-5 is the correct 235/45R17 radial size on a 17-inch wheel. Because this is a modern-era Saab rather than an older bias-ply vehicle, staying with the proper metric radial format preserves the car’s intended visual balance better than trying to force a vintage-style look.
Appearance decisions within this fitment are fairly restrained, since the available options are blackwall tires rather than decorative sidewall treatments. The most important restoration-oriented move is keeping the size and wheel relationship correct, then choosing a tire series that suits how the car will be presented and driven.
Does correct tire fitment matter for a 2008 Saab 9-5 restoration?
Correct tire fitment matters on a 2008 Saab 9-5 because the car’s stance, wheelwell appearance, and overall presentation depend heavily on using the proper 235/45R17 radial size. Even on a newer collector-era car, the wrong profile or wheel relationship can change the visual character quickly.
Fitment also matters mechanically, since an incorrect size can create clearance issues or alter the way the car sits on its wheels. Buyers aiming for a careful restoration should verify the actual wheels on the car and compare any replacement choice against the intended 17-inch setup before moving ahead.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Saab 9-5?
Yes, modifications can affect tire fitment on a 2008 Saab 9-5 even when the original size is 235/45R17. Changes such as aftermarket wheels, suspension lowering, different offsets, or body alterations can influence how much room the tire has under steering and suspension movement.
That matters because the factory-style size does not automatically guarantee the same result on a modified car. A quick inspection of wheel diameter, wheel width, offset, and inner and outer clearance is the safest way to confirm that a new 235/45R17 tire still suits the Saab’s current setup.
What should I inspect before driving a 2008 Saab 9-5 on new tires?
Before driving a 2008 Saab 9-5 on new tires, inspect the wheels for damage, confirm the 17-inch wheel setup, and make sure the tires are mounted in the correct 235/45R17 size. It also helps to check air pressure, valve stems, and overall clearance at full steering lock.
A roadworthy check should include suspension and alignment condition as well, since worn components can affect how new tires behave and wear. Looking over brakes, wheel bearings, and any signs of rubbing is especially worthwhile on a car that has sat for long periods or changed hands recently.
How often should tires on a 2008 Saab 9-5 be inspected?
Tires on a 2008 Saab 9-5 should be inspected regularly, especially on a car that is driven occasionally rather than every day. Pressure loss, uneven wear, sidewall damage, cracking, or embedded road debris can develop gradually and may not be obvious until the car is back in use.
A good habit is to check the tires before longer drives and anytime the Saab has been stored for a while. Looking at tread condition, sidewalls, and air pressure helps catch problems early, and it is also a useful time to confirm there has been no rubbing or contact inside the wheelwell.
