The 2009 Saab 9-5 comes from the final stretch of Saab’s long-running midsize flagship, a car known for its understated Swedish design, turbocharged character, and practical blend of sport sedan and wagon versatility. For owners keeping one on the road today, tire choice matters as much for stance and response as it does for everyday drivability. This exact model uses a 235/45R17 radial fitment across its covered sub-models, keeping the sizing decision straightforward. The real comparison is between available blackwall performance-oriented radial choices from BFGoodrich and Nitto. For a well-kept 9-5, the priority is matching the correct 17-inch fitment to the car’s wheel setup, condition, and intended use.
Which Tire Size Is Right for The 2009 Saab 9-5
The 2009 Saab 9-5 uses one primary tire size: 235/45R17. It is a radial tire on a 17-inch rim, and that same fitment carries across the covered sedan and SportCombi sub-models. Since size selection is simple here, the real decision becomes choosing the right product within that fitment based on tire series, brand, blackwall presentation, and how the car is actually driven.
A 235/45R17 tire uses a 235-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2009 Saab 9-5, this is a modern radial fitment that suits the car’s later-era sport-touring character and keeps the size interpretation familiar for today’s buyer. Available choices in this size include BFGoodrich and Nitto blackwall tires across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2. The practical comparison is less about fitment variation and more about selecting a tire that matches your wheel width, intended road use, and preferred driving feel.
Tire fitment is straightforward across the covered 2009 Saab 9-5 range because each listed sub-model uses the same primary size. That consistency simplifies selection, but checking the exact sub-model still helps confirm that the car remains on its intended wheel setup.

2009 Saab 9-5 2.3t Sedan
The 2009 Saab 9-5 2.3t Sedan uses the shared 235/45R17 radial fitment found across the covered range. That makes tire selection more about choosing the right blackwall radial product and confirming the sedan still has the correct 17-inch wheel setup.
The 2009 Saab 9-5 2.3t SportCombi uses the same 235/45R17 radial size as the other covered sub-models. For this wagon configuration, the key step is selecting a suitable product within that size and verifying wheel condition, width, and overall setup before replacement.
The 2009 Saab 9-5 Aero Sedan also uses the shared 235/45R17 radial fitment. Since the size itself does not vary here, the focus shifts to comparing available tire series and making sure the car’s current wheels still match the intended 17-inch application.
The 2009 Saab 9-5 Aero SportCombi uses 235/45R17 radial tires, matching the rest of the covered lineup. That keeps size choice simple, while still leaving room to compare product character, wheel-width compatibility, and whether the wagon has any aftermarket wheel or suspension changes.
The 2009 Saab 9-5 Griffin Sedan follows the same 235/45R17 radial tire fitment as the other listed versions. With no sub-model size split to sort out, the important next step is choosing among the available blackwall radial offerings and confirming the existing wheel specification.
The 2009 Saab 9-5 Griffin SportCombi uses the shared 235/45R17 radial size. That means selection centers on product choice rather than alternate fitments, along with a quick check that the car’s wheels and overall stance have not been changed from this 17-inch 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.

Tire Size & Fitment
What tire size fits a 2009 Saab 9-5?
The 2009 Saab 9-5 uses a 235/45R17 radial tire. That size applies across the covered 2.3t, Aero, and Griffin versions in both Sedan and SportCombi form, so the primary fitment question is unusually straightforward for this model year.
Once the size is confirmed, the next step is making sure the car still has the intended 17-inch wheel setup. A previous owner may have changed wheels or suspension, so it helps to verify actual rim width, inspect clearance at full steering lock, and match the new tire to how the car is driven.
What size rim does a 2009 Saab 9-5 use?
The 2009 Saab 9-5 fitment here is built around a 17-inch rim. Its primary tire size, 235/45R17, is a radial size intended for that wheel diameter, which makes rim confirmation simple as long as the car remains on its expected wheel package.
Wheel diameter is only part of the check. Tire options in this size are paired with rim-width ranges, so the actual wheel width matters too, especially if the car has aftermarket wheels. Confirming both diameter and width helps avoid a mismatch that can affect tire shape, response, and clearance.
Do all 2009 Saab 9-5 sub-models use the same tire size?
Yes. The covered 2009 Saab 9-5 2.3t Sedan, 2.3t SportCombi, Aero Sedan, Aero SportCombi, Griffin Sedan, and Griffin SportCombi all use the same 235/45R17 radial tire size. That shared fitment removes the usual sub-model size confusion from the buying process.
Even with common sizing across the range, it is still smart to inspect the car before replacement. A wagon, sedan, or performance-oriented trim may now be riding on different wheels than intended, and that can change what actually fits. Checking the mounted wheel dimensions keeps the tire choice grounded in the car’s current setup.
Choosing the Right Tire
What should I consider when choosing a 235/45R17 tire for a 2009 Saab 9-5?
Start with the correct size and construction: 235/45R17 radial on a 17-inch wheel. From there, compare the tire series available in that fitment, along with brand, blackwall presentation, rim-width compatibility, and any load or service details shown on the individual product.
A 9-5 kept as a daily driver may call for a different product emphasis than one used mainly for fair-weather touring. It helps to confirm actual wheel width, inspect suspension and alignment condition, and choose a tire that suits the car’s use rather than selecting by size alone.
What sidewall styles are available for 2009 Saab 9-5 tires?
The available 235/45R17 options for the 2009 Saab 9-5 use a blackwall sidewall style. That suits the car’s modern sport-sedan and sport-wagon presentation, and it keeps the visual choice simple compared with classic applications that offer whitewalls, redlines, or other period-style sidewall treatments.
Because all of the current options are blackwall, selection comes down more to tire series and brand than to appearance differences at the sidewall. Owners who want the car to maintain a clean, understated look can focus on wheel fit, tread category, and overall tire condition without sorting through multiple sidewall themes.
What brands offer tires for the 2009 Saab 9-5?
BFGoodrich and Nitto both offer tires in the 235/45R17 fitment used on the 2009 Saab 9-5. Within those brands, the available choices include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, and the Nitto NT555 G2, all in blackwall radial form.
Brand alone should not make the decision. It is more useful to compare the specific tire series, the wheel-width range each tire supports, and the condition of the car’s current setup. Looking at those details gives a clearer picture than choosing by name while assuming every 235/45R17 behaves the same.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Saab 9-5?
A period-style 2009 Saab 9-5 starts with the correct 235/45R17 radial size on a 17-inch wheel. Since the available options here are modern blackwall radials, the closest visual match comes from staying within that original-looking size and avoiding a change that alters the car’s stance or overall proportion.
For this era of Saab, appearance is usually preserved more by correct dimensions and a clean sidewall than by vintage-style trim details. Keeping the proper size, checking ride height, and making sure the wheels are appropriate to the car will do more for the finished look than chasing a tire that simply sounds sportier.
Does correct tire fitment matter for a 2009 Saab 9-5 restoration?
Yes, correct tire fitment matters on a 2009 Saab 9-5 restoration because the tire size has a direct effect on stance, wheel-well fill, and the car’s overall visual balance. Staying with the proper 235/45R17 radial format keeps the restored car closer to the look expected for this late-model Saab.
A restoration-minded owner should also verify that the wheels themselves belong with the intended presentation of the car. Tires cannot correct an unsuitable wheel diameter or width, and they should not be used to disguise suspension issues. Getting the fitment foundation right gives the finished car a more convincing, cohesive appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Saab 9-5?
Yes. A 2009 Saab 9-5 may use the correct 235/45R17 size on paper, but aftermarket wheels, altered wheel offset, lowered suspension, or body changes can all affect actual fitment. Even when the size stays the same, the car’s clearance and tire-to-wheel relationship may no longer match a stock setup.
The safest approach is to inspect the car as it sits before replacing tires. Check wheel diameter and width, look for rubbing marks at the inner fender and suspension, and turn the steering from lock to lock. That simple review helps prevent choosing a tire that matches the label but not the car’s real configuration.
What should I inspect before driving a 2009 Saab 9-5 on new tires?
Before road use, inspect tire pressure, wheel fastener torque, valve stems, tread seating, and any obvious signs of rubbing or uneven alignment. A 2009 Saab 9-5 should also have its wheels checked for bends or damage, since even a correct 235/45R17 tire cannot compensate for a compromised rim.
It also helps to look over suspension and steering components if the car has been sitting or has seen inconsistent maintenance. Worn bushings, weak dampers, or poor alignment can shorten tire life quickly. A brief inspection after the first few miles can confirm that the tires are wearing evenly and clearing properly.
How often should tires on a 2009 Saab 9-5 be inspected?
Tires on a 2009 Saab 9-5 should be inspected regularly, not just when tread looks low. Monthly pressure checks are a smart baseline, and the tires should also be looked over for cuts, bulges, cracking, irregular wear, or slow air loss, especially on a car that is driven infrequently.
Collector-minded or lightly used cars can develop tire issues simply from age, storage, or long periods of sitting. A quick visual inspection before each longer drive helps catch problems early. It is also worth checking alignment wear patterns from time to time, since a worn front-end component can show up at the tire first.
