The 1979 Saab 99 came from a period when Saab’s practical engineering and distinctive Scandinavian design had already earned the model a loyal following. Known for its solid road manners and everyday usability, the 99 remains a thoughtful choice for enthusiasts who appreciate unusual but highly usable late-classic European cars. Tire fitment for the 1979 Saab 99 is straightforward, centered on a 165R15 radial on a 15-inch rim. Within that size, there is still room to choose among blackwall, narrow whitewall, and wide whitewall styles, along with touring-oriented classic radial series. The real decision is matching the tire’s look, construction details, and wheel compatibility to the way the car is restored and driven.
Which Tire Size Is Right for The 1979 Saab 99
The 1979 Saab 99 uses one primary tire size: 165R15, a radial tire for a 15-inch rim. The covered Base sub-model uses that same size, so the main decision is not choosing between primary fitments, but selecting the right 165R15 tire by sidewall style, tire series, intended road use, and wheel-width compatibility.
A 165R15 size uses a nominal section width of 165 millimeters, radial construction, and a 15-inch rim diameter. In this format, the aspect ratio is not stated in the size code and is commonly associated with an 80-series profile, which suits the 1979 Saab 99’s original-era tire character. Available choices include blackwall, narrow whitewall, and wide whitewall options from brands such as Michelin, Firestone, BFGoodrich, American Classic, Coker Classic, and Vredestein across several radial series. This size works best when the wheel width and the car’s actual setup are confirmed before choosing among appearance-focused or road-use-focused versions.
Fitment is simple across the covered 1979 Saab 99 sub-model range. The Base model uses the same primary tire size, so selection comes down to the type of 165R15 radial you want rather than sorting through multiple factory fitments.

Tire Size & Fitment
What tire size fits a 1979 Saab 99?
The 1979 Saab 99 uses a 165R15 radial tire. That is the primary fitment for this model year and it matches a 15-inch rim, giving the car the tall-profile Euro-metric radial look typical of many imported cars from the period.
Because there is one primary size, the next step is choosing the right version of 165R15 rather than choosing between multiple fitments. Sidewall style, tire series, and wheel-width compatibility are the details that matter most, especially if the car has non-original wheels or has been restored with appearance goals in mind.
What size rim does a 1979 Saab 99 use?
The 1979 Saab 99 uses a 15-inch rim with its 165R15 tire size. Product options in this size cover several approved rim-width ranges, generally starting around 4 inches or 4.5 inches and extending to 5.5, 6, or in one case 7 inches depending on the tire.
Rim diameter is the first non-negotiable detail, but rim width still affects which 165R15 tire makes sense. Measuring the actual wheel before ordering is worthwhile, particularly on a car that may have had replacement wheels installed over the years or that is being set up for a particular period-style appearance.
Does the 1979 Saab 99 Base use the same tire size?
Yes. The 1979 Saab 99 Base uses the same 165R15 radial tire size as the core fitment for this model. That keeps selection relatively straightforward, since there is no separate primary size to sort out for the covered sub-model.
Even with shared fitment, the right tire still depends on how the car is equipped today. Whitewall versus blackwall appearance, brand preference, and wheel-width compatibility can all influence the final choice, so it helps to confirm the wheel setup and decide whether the priority is a stock-looking presentation or a simple road-use replacement.
Choosing the Right Tire
What should I consider when choosing a 165R15 tire for a 1979 Saab 99?
Start with the basics: the tire should be a 165R15 radial for a 15-inch rim, and the selected product should suit the wheel width on the car. Beyond that, the main differences are sidewall style, tire series, and brand, since this size is offered in several classic radial lines.
A blackwall tire usually gives the Saab a cleaner European-driver look, while narrow or wide whitewalls create a more styled presentation. It also helps to compare rim-width compatibility and load figures where they are given, especially if the car sees regular road use rather than occasional display or light seasonal driving.
What sidewall styles are available for 1979 Saab 99 tires?
The 1979 Saab 99 has 165R15 tire options in blackwall, narrow whitewall, and wide whitewall styles. Those choices appear across multiple classic radial series, so the sidewall treatment can change the car’s presentation even when the tire size remains the same.
For a restrained imported-car look, blackwall is often the simplest visual match. Whitewall options move the car toward a more stylized period presentation, so the right choice depends on how the Saab is being restored and what appearance suits its trim, wheels, and overall stance without assuming any one sidewall was universal.
What brands offer tires for the 1979 Saab 99?
The 165R15 size for the 1979 Saab 99 is available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein. Those brands cover several distinct tire series, including blackwall and whitewall options within the same basic size and radial construction.
Brand choice should be part of a broader comparison rather than the only factor. Looking at sidewall style, rim-width range, and the character of the tire series usually gives a clearer path to the right fit for the car, especially when balancing road use, period-style appearance, and the wheel setup currently on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1979 Saab 99?
A 165R15 radial is the proper starting point for a period-style 1979 Saab 99 because it preserves the car’s original-era sizing format and 15-inch rim fitment. From there, the decision usually comes down to whether the car looks most appropriate with a blackwall, narrow whitewall, or wide whitewall presentation.
For many Saab restorations, blackwall keeps the look closer to the understated European character the car is known for. If exact originality matters, compare the tire choice against period photos, marque-club guidance, and the specific car’s history, since sidewall treatment and brand preference can vary among restored examples.
How does tire construction affect the appearance of a restored 1979 Saab 99?
On a 1979 Saab 99, construction is straightforward because the primary fitment is already radial. That means the visual difference usually comes less from bias-ply-versus-radial questions and more from the specific radial selected, especially the sidewall treatment and the overall character of the tire series.
A blackwall radial tends to preserve a more restrained, European look, while whitewall versions create a more customized or display-oriented presentation. Since all of the primary choices remain within the 165R15 radial format, restoration appearance is shaped mainly by visual details and wheel compatibility rather than by changing tire construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1979 Saab 99?
Yes. Even though the standard fitment is a 165R15 radial on a 15-inch rim, modifications can change what works safely and cleanly on the car. Aftermarket wheels, changes in rim width, suspension work, or body and steering adjustments can all affect clearance and the way the tire sits on the wheel.
Checking the actual wheel diameter and width is especially important on an older Saab that may have changed hands several times. A tire in the correct size still needs to suit the wheel and clear the car through full steering travel and normal suspension movement before it is treated as a practical road-use choice.
What should I inspect before driving a 1979 Saab 99 on new tires?
Start by confirming that the tires are the correct 165R15 size and that each tire is mounted on a compatible 15-inch wheel. Then inspect air pressure, valve stems, wheel condition, lug hardware, and basic clearance at the fenders and suspension so the car is ready for initial road use.
A short shakedown drive is wise before any longer trip. Pay attention to rubbing, pulling, vibration, or unusual steering feel, and recheck pressure after the first outing. On collector cars that spend time parked, it also makes sense to look over the rest of the chassis for age-related issues before expecting the new tires to solve everything.
How should 165R15 tires on a collector 1979 Saab 99 be maintained?
165R15 tires on a collector-era 1979 Saab 99 should be checked regularly for pressure, tread wear, cracking, cuts, bulges, and slow air loss. Low-mileage collector cars often age their tires by time and storage conditions rather than by mileage alone, so visual inspection matters as much as tread depth.
Storage habits also affect tire life. Keeping the Saab away from prolonged sunlight, excess heat, standing moisture, and ozone sources such as electric motors helps preserve the rubber, and moving or driving the car periodically can help prevent long-term flat spotting. Any sign of age-related deterioration deserves attention before regular road use.
