The 2011 Saab 9-5 arrived as Saab’s final full-size luxury sport sedan, blending Scandinavian design, long-distance comfort, and a more contemporary performance feel than earlier generations. For many owners, it stands apart as a late-era Saab that still rewards careful, model-specific upkeep. Tire selection on the 2011 Saab 9-5 centers on three radial sizes: 225/55R17, 245/45R18, and 245/40R19, with fitment changing by sub-model and wheel package. Available choices range from blackwall performance-oriented tires to Silvertown Radial options in wide whitewall and redline form on 225/55R17. The key is matching the exact sub-model and wheel diameter before comparing appearance, series, and road-use priorities.
Which Tire Size Is Right for The 2011 Saab 9-5
The 2011 Saab 9-5 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they span 17-inch, 18-inch, and 19-inch rims, so the first step is confirming the wheels currently on the car before choosing among available tire series, sidewall styles, and performance-oriented options.
A 245/40R19 tire uses a 245-millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim. On the 2011 Saab 9-5, this size suits a larger-wheel setup and keeps the fitment in a modern metric radial format familiar to current buyers. Available choices in this size come from BFGoodrich across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A blackwall lines. This is the size to evaluate when the car carries 19-inch wheels and the goal is to stay with the proper rim diameter while comparing tire series within the same fitment.
A 245/45R18 tire has the same nominal 245-millimeter width as the 19-inch option, but with a 45-series profile on an 18-inch rim. For the 2011 Saab 9-5, it is one of the main sub-model fitments and remains a straightforward radial size rather than a vintage-style designation. BFGoodrich and Nitto both offer blackwall choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right size to compare when the car is equipped with 18-inch wheels and the buyer wants to stay within the correct wheel diameter while sorting through available brand and series differences.
A 225/55R17 tire uses a narrower 225-millimeter section width, a 55-series profile, radial construction, and a 17-inch rim. On the 2011 Saab 9-5, this size belongs to the 17-inch wheel fitment and offers the broadest range of visual presentation among the available options. BFGoodrich choices include blackwall g-Force lines as well as Silvertown Radial versions in wide whitewall and redline. This size deserves a closer look when the car runs 17-inch wheels and the buyer wants either a modern blackwall appearance or a more distinctive sidewall treatment without changing the primary fitment.
Tire fitment on the 2011 Saab 9-5 varies by sub-model, and some versions were offered with more than one wheel and tire package. Identifying the exact sub-model matters because the correct tire size is tied directly to the rim diameter already on the car.

2011 Saab 9-5 Aero
The 2011 Saab 9-5 Aero uses either a 245/40R19 or 245/45R18 radial tire, so wheel diameter must be confirmed before selecting a replacement. That makes the Aero the most important sub-model to check visually, since the decision starts with 18-inch versus 19-inch wheels and then moves to brand and tire-series preference.
The 2011 Saab 9-5 Turbo4 uses the 225/55R17 radial size. Tire selection here is more straightforward, with choices that range from blackwall performance-oriented radials to Silvertown Radial options that change the car’s visual presentation without changing its primary size.
The 2011 Saab 9-5 Turbo4 Premium uses the 245/45R18 radial size. The main buying decision is not the fitment itself, but which blackwall tire series best suits the car’s current use, wheel setup, and preferred balance of appearance and driving character.
The 2011 Saab 9-5 Turbo6 uses the 245/45R18 radial size. With the correct 18-inch wheel in place, the focus shifts to comparing available blackwall options by brand, tire series, and wheel-width compatibility rather than sorting through multiple primary sizes.
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 2011 Saab 9-5 Tires for Sale
Available 2011 Saab 9-5 tires center on radial blackwall choices from BFGoodrich and Nitto in the 18-inch and 19-inch sizes, while 225/55R17 also adds Silvertown Radial options in wide whitewall and redline for a more distinctive appearance.
Common 2011 Saab 9-5 tire questions usually come down to sub-model fitment, wheel diameter, available radial sizes, and how to choose among blackwall, redline, or wide whitewall options. The answers below focus on practical size selection, appearance, and road-use checks.
Tire Size & Fitment
What tire size fits a 2011 Saab 9-5?
The 2011 Saab 9-5 uses three primary radial tire sizes: 225/55R17, 245/45R18, and 245/40R19. The exact size depends on the sub-model and wheel package, with Turbo4 using 225/55R17, Turbo4 Premium and Turbo6 using 245/45R18, and Aero using either 245/45R18 or 245/40R19.
The most important next step is confirming the actual wheel diameter on the car. A 17-inch, 18-inch, or 19-inch rim requires the matching tire size, and an Aero can carry two different fitments. Once the wheel size is verified, the buying decision becomes much easier because the remaining choices stay within one correct tire size.
What size rim does a 2011 Saab 9-5 use?
A 2011 Saab 9-5 can use 17-inch, 18-inch, or 19-inch rims depending on the sub-model and wheel setup. The 225/55R17 tire fits a 17-inch rim, the 245/45R18 fits an 18-inch rim, and the 245/40R19 fits a 19-inch rim.
Rim diameter should be checked before anything else because the tire size is tied directly to it. Looking only at the model year is not enough on this car, especially with the Aero using more than one fitment. If the car has changed hands or received aftermarket wheels, verify the wheel markings and current size before selecting tires.
Why does the 2011 Saab 9-5 have more than one tire size?
The 2011 Saab 9-5 has more than one tire size because fitment varies by sub-model and wheel package. Turbo4, Turbo4 Premium, Turbo6, and Aero do not all use the same wheel diameter, and the Aero itself can use either 18-inch or 19-inch wheel-and-tire combinations.
That variation means tire selection starts with identifying the exact version of the car and confirming the wheels currently installed. Even though the overall tire diameters are close across the three sizes, they are not interchangeable as primary fitments. Matching the tire to the wheel diameter already on the vehicle is the essential first step.
Choosing the Right Tire
What should I consider when choosing a 2011 Saab 9-5 tire?
Start with the correct tire size for the car’s sub-model and wheel diameter, then compare construction details within that fitment. The 2011 Saab 9-5 uses radial tires only, so the real choice is among tire series, brand, sidewall style, rim-width compatibility, and, in some sizes, load figures and overall product character.
A buyer with a Turbo4 on 17-inch wheels may focus on whether a blackwall, redline, or wide whitewall better suits the car’s presentation, while an 18-inch or 19-inch setup points more toward blackwall performance-oriented options. It also helps to compare the wheel-width range against the wheels already on the car before narrowing the product list.
What sidewall styles are available for 2011 Saab 9-5 tires?
Sidewall style depends on tire size. The 18-inch and 19-inch 2011 Saab 9-5 fitments are offered in blackwall form, while the 225/55R17 size also includes Silvertown Radial options in wide whitewall and redline, giving the 17-inch fitment the broadest appearance range.
That matters most for owners using the Turbo4 17-inch setup, because sidewall treatment can change the car’s visual character without changing its primary size. Blackwall remains the standard contemporary look, while redline or wide whitewall creates a more customized or retro-inspired presentation. The key is staying with the correct 225/55R17 size on the proper 17-inch wheel.
What brands offer tires for the 2011 Saab 9-5?
The 2011 Saab 9-5 is covered here by BFGoodrich and Nitto, depending on size. BFGoodrich appears across all three primary sizes, while Nitto is available in 245/45R18. Tire series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Silvertown Radial, and Nitto NT555 G2.
Brand choice should follow the correct size and wheel setup rather than lead the decision. A Turbo6 or Turbo4 Premium owner comparing 245/45R18 tires can weigh BFGoodrich and Nitto within the same fitment, while a 225/55R17 buyer has a wider spread of appearance options through BFGoodrich alone. Matching the brand choice to the proper size keeps the process grounded.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Saab 9-5?
A period-style approach on a 2011 Saab 9-5 still begins with the correct original fitment size for the car’s sub-model and wheel diameter. Since this is a modern radial-fitment car, the closest appearance decisions come from sidewall style and tire series rather than from choosing between vintage bias-ply and radial construction.
The 225/55R17 size offers the most visual flexibility because it is available in blackwall, redline, and wide whitewall form. That makes it the easiest fitment for an owner who wants a distinctive presentation. On 18-inch and 19-inch cars, the appearance choice is more restrained, so the emphasis stays on proper size, wheel match, and a clean blackwall look.
How does tire construction affect the appearance of a restored 2011 Saab 9-5?
On the 2011 Saab 9-5, construction does not create the same visual divide seen on older collector cars because the primary fitments are radial across all three sizes. The visible differences come more from sidewall treatment and tread style than from a bias-ply-versus-radial decision.
That means a restoration-oriented buyer should focus first on the correct size and wheel diameter, then decide how subtle or expressive the finished look should be. Blackwall keeps the presentation modern and understated, while 225/55R17 allows a stronger visual statement through redline or wide whitewall styling. Careful wheel and size matching keeps the look intentional rather than improvised.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Saab 9-5?
Yes, modifications can affect tire fitment on a 2011 Saab 9-5. Aftermarket wheels, suspension changes, ride-height adjustments, or body alterations can change the clearances that the original 225/55R17, 245/45R18, or 245/40R19 fitments were designed around.
A car that no longer has its original wheel setup should be measured carefully before replacement tires are chosen. Check wheel diameter, wheel width, and available clearance at the fender, steering, and suspension points. Even when the tire size matches a known Saab 9-5 fitment, the actual car still needs to be evaluated as it sits today.
What should I inspect before driving a 2011 Saab 9-5 on new tires?
Before driving a 2011 Saab 9-5 on new tires, inspect the wheels for correct diameter and condition, then confirm proper inflation and look over the tire sidewalls and tread after mounting. Lug hardware, valve stems, and basic wheel balance should also be checked before putting miles on the car.
It also helps to make a slow steering-lock check to confirm there is no rubbing and to recheck air pressure after the first few drives. On a car with uncertain service history, a quick look at suspension wear and alignment condition is worthwhile too. New tires perform best when the wheel and chassis condition support them.
What should I check before a longer drive in a 2011 Saab 9-5?
Before a longer drive, make sure the 2011 Saab 9-5 has the correct tire size for its wheel diameter, proper air pressure, and no visible signs of damage such as cuts, bulges, or irregular tread wear. A quick inspection of all four tires is especially important if the car has been parked for extended periods.
A longer trip is also the right time to confirm that the spare-wheel arrangement, if carried, matches the car’s needs and that the current tires are aging evenly. Uneven wear can point to alignment or suspension issues that become more noticeable at highway speed. Catching those details early helps protect both ride quality and tire life.
