The 1975 Saab 99 came from an era when Saab sedans stood apart for their practical engineering, distinctive shape, and strong road manners in demanding weather. For many owners, that means tire choice is as much about preserving the car’s character as it is about simple replacement. This model uses 15-inch radial fitments, with 165R15 covering the base 99 and also appearing on the EMS, while some EMS applications use 175/70R15. Available choices range from blackwall to narrow and wide whitewall designs, with several classic radial series represented. The key is matching the right size to the exact version of the car and the look and driving use you want.
Which Tire Size Is Right for The 1975 Saab 99
Two tire sizes apply to the 1975 Saab 99, and both are radial tires built for 15-inch wheels. The first step is confirming the exact sub-model, because the Base uses 165R15 while the EMS can use either 165R15 or 175/70R15. Once the correct size is identified, the decision shifts to sidewall appearance, tire series, and the kind of road use or restoration style that best matches the car.
165R15 is a Euro-metric radial size that uses a 165-millimeter nominal section width and a 15-inch rim, with no aspect ratio stated in the size itself. On the 1975 Saab 99, it is a primary radial fitment and represents the more traditional sizing format found on many European cars of the period. This size has the broadest product variety, including blackwall, narrow whitewall, and wide whitewall options from brands such as Michelin, Firestone, BFGoodrich, Coker Classic, American Classic, and Vredestein. It is the size to evaluate when preserving a period-style presentation or comparing among the widest range of available radial choices.
175/70R15 is a metric radial size that uses a 175-millimeter section width, a 70-series aspect ratio, and a 15-inch rim. On the 1975 Saab 99, this size is associated with certain EMS applications rather than the full model range, so it should be chosen only after confirming the exact setup. Product selection in this size centers on blackwall radials, including Avon and Vredestein offerings in established performance-oriented classic radial lines. It is a useful fitment to review when the car calls for the EMS-specific size and the goal is a proper 15-inch radial in that modern metric format.
Sub-model fitment matters on the 1975 Saab 99 because tire size is not identical across the range. The Base stays with one primary size, while the EMS can use two radial fitments, so confirming the exact version of the car is the first step before comparing tires.

1975 Saab 99 Base
The 1975 Saab 99 Base uses the 165R15 radial size. That makes tire selection more straightforward, with the main decision centered on blackwall versus whitewall appearance, brand preference, and whether the car is being kept in a more traditional road-going presentation.
The 1975 Saab 99 EMS uses either 165R15 or 175/70R15, so size confirmation matters before any tire is selected. Once the exact fitment is established, the choice becomes a comparison of available blackwall classic radials or, where applicable, a broader period-style selection in 165R15.
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.

Owners of a 1975 Saab 99 usually need to sort out the correct size first, then compare radial formats, sidewall styles, and product choices. The questions below focus on fitment, selection, appearance, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 1975 Saab 99?
The 1975 Saab 99 uses two 15-inch radial tire sizes: 165R15 and 175/70R15. The Base model uses 165R15, while the EMS can use either 165R15 or 175/70R15 depending on the specific setup. Both sizes are radial fitments rather than bias-ply sizes.
That means the most important step is identifying whether the car is a Base or EMS and then confirming which size is actually on the vehicle. A 15-inch wheel is common to both, but the tire size itself still needs to match the car’s configuration and wheel setup before comparing brands, sidewall styles, or tire series.
What size rim does a 1975 Saab 99 use?
The 1975 Saab 99 uses a 15-inch rim diameter with both of its primary tire sizes. That applies to 165R15 and 175/70R15, so the wheel diameter stays consistent even though the tire sizing format differs between the two fitments.
Rim diameter is only part of the fitment picture, so it is worth checking wheel width as well before choosing a tire. Product options in these sizes cover different approved rim-width ranges, and that matters if the car has replacement wheels, restored original wheels, or any wheel change from its earlier service life.
Do all 1975 Saab 99 sub-models use the same tire size?
No. The 1975 Saab 99 Base uses 165R15, while the EMS can use either 165R15 or 175/70R15. Both are radial tires for 15-inch wheels, but the EMS introduces a second fitment that the Base does not share.
That difference makes the sub-model important when ordering tires or evaluating what is already on the car. An EMS owner should verify the current wheel and tire setup rather than assume every 99 uses the same size, especially if the car has seen past maintenance changes, aftermarket wheels, or a long restoration history.
Choosing the Right Tire
What should I consider when choosing a 165R15 tire for a 1975 Saab 99?
A 165R15 tire for a 1975 Saab 99 should first match the correct vehicle application, then be compared by sidewall style, tire series, and wheel compatibility. In this size, choices include blackwall, narrow whitewall, and wide whitewall radials across several classic product lines.
The practical decision usually comes down to how the car will be used and how traditional you want it to look. A road-driven Saab may call for one type of classic radial presentation, while a restoration-oriented car may lean toward a whitewall treatment, provided the wheel width and overall setup suit the tire being considered.
What sidewall styles are available for 1975 Saab 99 tires?
Sidewall choices for the 1975 Saab 99 include blackwall, narrow whitewall, and wide whitewall, depending on tire size and series. The broadest appearance range is in 165R15, where traditional whitewall treatments sit alongside more understated blackwall options.
That gives owners room to tailor the car’s presentation without changing the primary fitment itself. A blackwall usually keeps the look more restrained and European, while narrow or wide whitewalls create a more pronounced vintage visual effect, so the right choice depends on the style of restoration or road-use appearance you want.
What brands offer tires for the 1975 Saab 99?
Tires for the 1975 Saab 99 are available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, Vredestein, and Avon. Most of that brand variety appears in 165R15, while 175/70R15 is represented by Avon and Vredestein in blackwall radial offerings.
Brand choice should be considered alongside size, tire series, sidewall treatment, and wheel fitment rather than by name alone. Some buyers are looking for a traditional whitewall presentation, while others want a blackwall classic radial, so the better comparison is which product best matches the car’s intended use and visual character.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Saab 99?
For a period-style 1975 Saab 99, the starting point is the correct original fitment size for the exact sub-model, with 165R15 serving as the most traditional-looking option in the range. That size is available in several classic radial series and in blackwall, narrow whitewall, and wide whitewall forms.
The best choice depends on whether the goal is a restrained European sedan look or a more stylized restoration presentation. Exact originality claims should be checked against marque-specific historical references, but staying with the proper size and a classic radial design is the most reliable way to keep the car visually aligned with its era.
How does tire construction affect the appearance of a restored 1975 Saab 99?
On a restored 1975 Saab 99, tire construction affects the appearance less dramatically than on earlier bias-ply-era cars because the primary fitments here are already radial. The visible difference usually comes more from sidewall treatment and tread presentation than from a bias-ply-versus-radial decision.
That makes size and sidewall style especially important when shaping the finished look. A blackwall radial tends to preserve a clean, understated character, while narrow or wide whitewalls create a more noticeable vintage accent, so the appearance decision often comes down to the restoration style rather than a construction change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Saab 99?
Yes. Modifications can affect tire fitment on a 1975 Saab 99 even when the tire size itself is otherwise correct. Aftermarket wheels, wheel-width changes, suspension alterations, ride-height changes, or bodywork differences can all influence how a 165R15 or 175/70R15 tire sits and clears the car.
That is why the wheel and tire setup should be verified on the actual vehicle before making a final choice. Clearance at the fenders and steering components matters, and any non-original wheel should be checked for both diameter and width so the selected radial works with the car’s current configuration rather than an assumed stock one.
What should I inspect before driving a 1975 Saab 99 on new tires?
Before driving a 1975 Saab 99 on new tires, inspect the wheels for condition and correct size, confirm proper inflation, and look over the suspension and steering for anything that could affect tracking or clearance. It also helps to recheck lug hardware and make sure the tire seats correctly on the wheel.
A collector-era Saab may also have issues unrelated to the tire itself, such as aged rubber components, alignment drift, or long periods of storage that changed how the car sits. A short initial road test followed by a second pressure and visual check is a sensible way to catch rubbing, settling, or air loss early.
How should tires on a collector 1975 Saab 99 be maintained?
Tires on a collector 1975 Saab 99 should be kept at appropriate pressure, inspected regularly for cracks, bulges, cuts, and uneven wear, and protected from long exposure to heat, sunlight, and ozone sources. Cars that are driven infrequently still need routine tire checks because age and storage can affect condition even with low mileage.
Regular visual inspections matter just as much as tread depth on an older hobby car. Moving the car periodically, storing it on a clean dry surface, and checking for slow air loss can help preserve the tires between drives, while any vibration or handling change should prompt a fresh inspection of both the tires and the wheel setup.
