The 1989 Saab 900 sits in the final stretch of Saab’s original front-wheel-drive hatchback and sedan era, a period when the car’s aircraft-inspired design, turbocharged performance image, and distinctive Scandinavian character had already earned a loyal following. Tire fitment on this exact model stays firmly in the radial world, with 185/65R15 used on most 900 sub-models and 195/60R15 used on the SPG. That creates a practical choice between standard fitment and the sportier SPG size, along with sidewall treatments ranging from blackwall and raised white letter to redline and wide whitewall. The right selection depends on sub-model, intended appearance, and confirming that the car still carries its correct 15-inch wheel setup.
Which Tire Size Is Right for The 1989 Saab 900
The 1989 Saab 900 uses two primary tire sizes, and the right one depends on the exact sub-model. Both are radial tires for 15-inch rims, but most versions use 185/65R15 while the SPG uses 195/60R15. The first step is confirming whether the car is a Base, S, Turbo, or SPG, then comparing tire style, sidewall treatment, and wheel compatibility within that correct size.
185/65R15 is a metric radial size in which 185 identifies section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1989 Saab 900, this is the primary size used on the Base, S, and Turbo sub-models. Available choices stay within a traditional radial format but vary in presentation, including wide whitewall and redline versions in the BFGoodrich Silvertown Radial series. This size is the right starting point when the car retains its standard 15-inch setup and the goal is to match the proper fitment for those non-SPG configurations.
195/60R15 is also a metric radial size, with a 195-millimeter section width, a 60-series profile, radial construction, and a 15-inch rim diameter. On the 1989 Saab 900, this size belongs to the SPG, giving that sub-model its own fitment path rather than sharing the more common 185/65R15 size. Product choices include blackwall, redline, wide whitewall, and raised white letter styles, with offerings from BFGoodrich and Michelin across different tire series. This is the size to evaluate when the car is an SPG and still uses the wheel and clearance setup intended for that configuration.
Sub-model fitment matters on the 1989 Saab 900 because one version uses a different tire size from the rest. Base, S, and Turbo models share the same radial fitment, while the SPG moves to its own 15-inch radial size, so confirming the exact sub-model comes before comparing tire options.

1989 Saab 900 Base
The 1989 Saab 900 Base uses the 185/65R15 radial tire size on a 15-inch rim. Tire selection here is mainly about choosing the right sidewall style and product character while keeping the proper size for a standard Base-model wheel setup.
The 1989 Saab 900 S shares the 185/65R15 radial fitment used by most of the range. That keeps the decision centered on appearance and product style rather than changing size, provided the car still wears the correct 15-inch wheels.
The 1989 Saab 900 SPG uses 195/60R15 radial tires rather than the 185/65R15 size found on other sub-models. That makes wheel and sub-model confirmation especially important before choosing among blackwall, raised white letter, redline, or whitewall options.
The 1989 Saab 900 Turbo uses the 185/65R15 radial size, matching the Base and S models rather than the SPG. For a Turbo, the main decision is which available sidewall treatment and tire series best suit the car’s intended look and road use.
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 for the 1989 Saab 900 focus on the two correct tire sizes, how fitment changes by sub-model, what the 15-inch rim setup means, and how to choose between available radial tires for appearance, restoration style, and road use.
Tire Size & Fitment
What tire size fits a 1989 Saab 900?
The 1989 Saab 900 uses two tire sizes: 185/65R15 and 195/60R15. Base, S, and Turbo models use 185/65R15 radial tires, while the SPG uses 195/60R15 radial tires. Both sizes are designed for 15-inch wheels, but they are not the same fitment across all sub-models.
The practical step is to identify the exact sub-model before choosing a tire. A Base, S, or Turbo should be matched to 185/65R15 unless the car has been changed from its original wheel setup, while an SPG should be checked against its 195/60R15 fitment and wheel width before any replacement is selected.
What size rim does a 1989 Saab 900 use?
The 1989 Saab 900 uses 15-inch rims with both of its primary tire sizes. The 185/65R15 and 195/60R15 fitments each share the same 15-inch rim diameter, which means the main difference between them is the tire size itself rather than a change in wheel diameter.
That does not mean every 15-inch wheel is automatically suitable. Width still matters, and aftermarket wheels can change the fitment picture, so it is worth confirming the actual wheel width, the sub-model, and the car’s clearance before moving from one Saab 900 tire size to the other.
Do all 1989 Saab 900 sub-models use the same tire size?
No, the 1989 Saab 900 does not use one tire size across every sub-model. The Base, S, and Turbo use 185/65R15 radial tires, while the SPG uses 195/60R15. All four sub-models share a 15-inch rim diameter, but the tire dimensions and fitment path are different.
That difference matters when ordering replacements or evaluating the car in person. A Saab 900 with badges, wheels, or suspension parts changed over the years should be checked carefully so the tire choice matches the actual configuration, not just the name on the trunk or fender.
Choosing the Right Tire
What should I consider when choosing a 185/65R15 tire for a 1989 Saab 900?
For a 1989 Saab 900 that uses 185/65R15, the main factors are keeping the correct size, confirming the 15-inch wheel setup, and deciding what kind of appearance suits the car. In this size, BFGoodrich Silvertown Radial options are available with wide whitewall and redline sidewall treatments.
That means the decision is less about finding a fitment and more about selecting the presentation you want. A more traditional or restoration-oriented look may point toward one sidewall style, while a simpler visual approach may point toward another, but wheel width and overall condition should still be checked before installation.
What sidewall styles are available for 1989 Saab 900 tires?
The 1989 Saab 900 has several sidewall styles available, depending on tire size. Across the applicable products, sidewall choices include wide whitewall, redline, raised white letter, and blackwall. The broadest variety appears in 195/60R15, while 185/65R15 is offered in wide whitewall and redline versions.
Sidewall style changes the car’s presentation more than its basic fitment, so the right choice depends on whether the goal is a cleaner modern look, a sportier period flavor, or a more restoration-minded appearance. The first step is still choosing the correct size for the sub-model before narrowing by sidewall treatment.
What brands offer tires for the 1989 Saab 900?
The 1989 Saab 900 has tire options from BFGoodrich and Michelin in the sizes used on this model. BFGoodrich appears in both 185/65R15 and 195/60R15, while Michelin is available in 195/60R15 through the Primacy 3 line. Those choices give the buyer more than one direction depending on size and style.
Brand should be considered alongside tire series, sidewall treatment, and wheel compatibility rather than by itself. A buyer choosing for a standard Base, S, or Turbo fitment will be focused on the 185/65R15 offerings, while an SPG owner can compare both BFGoodrich and Michelin within the 195/60R15 size.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Saab 900?
A period-style 1989 Saab 900 tire choice starts with using the correct size for the exact sub-model. Base, S, and Turbo models should begin with 185/65R15, while the SPG should begin with 195/60R15. From there, available radial choices include more traditional-looking sidewall treatments such as redline or wide whitewall.
The right appearance depends on how the car is being presented. A driver-focused car may suit a simpler blackwall or raised white letter look, while a more restoration-oriented build may lean toward one of the styled sidewalls; if exact originality matters, marque-specific references should guide the final appearance decision.
How does tire construction affect the appearance of a restored 1989 Saab 900?
On the 1989 Saab 900, primary fitment remains radial, so the appearance question is less about bias-ply versus radial and more about sidewall presentation within the correct radial size. The available choices include blackwall, raised white letter, redline, and wide whitewall, depending on whether the car uses 185/65R15 or 195/60R15.
That makes construction straightforward but styling more personal. A restored Saab can look notably different with a blackwall touring-style tire than it does with a redline or whitewall, so matching the tire’s visual character to the car’s trim, wheels, and intended era impression is just as important as choosing the right size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Saab 900?
Yes, modifications can affect tire fitment on a 1989 Saab 900 even when the wheel diameter remains 15 inches. Aftermarket wheels, suspension changes, altered ride height, or previous owner changes between standard and SPG-style setups can all influence which tire size actually works on the car.
A modified Saab should be checked for wheel width, steering clearance, and fender room before replacement tires are chosen. That is especially important when a car appears to be one sub-model but carries another wheel package, since the factory size path for a Base, S, or Turbo differs from the SPG.
What should I inspect before driving a 1989 Saab 900 on new tires?
Before driving a 1989 Saab 900 on new tires, inspect the wheels for damage, confirm the rim diameter and width, and make sure the chosen size matches the car’s sub-model. It is also smart to check valve stems, lug hardware, alignment condition, and whether the old tires showed uneven wear patterns.
Once the tires are mounted, look for proper clearance at full steering lock and during suspension movement. A short test drive should be followed by another visual check for rubbing, air loss, or vibration, especially on cars that have sat for long periods or may have had wheel and suspension changes over time.
How should tires on a collector 1989 Saab 900 be maintained?
Tires on a collector 1989 Saab 900 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Watch for cracking, bulges, cuts, unusual tread wear, and slow air loss, since collector cars often spend long stretches parked and can age tires without adding much mileage.
A Saab 900 that is driven only occasionally benefits from being moved periodically and stored away from prolonged sunlight, heat, moisture, and ozone sources. It also helps to inspect the tires before every longer outing, because age, storage conditions, and long idle periods can matter just as much as tread depth.
