The 1977 Saab Saab 99 came from an era when Saab had firmly established its reputation for practical engineering, front-wheel-drive confidence, and a distinctly Scandinavian approach to everyday performance. Whether kept as a clean driver or preserved as a restoration-minded survivor, the 99 rewards careful attention to details that suit its original character. Tire fitment centers on 15-inch radial sizes, with 165R15 serving as the main fitment and 175/70R15 appearing on certain EMS applications. Available choices range from blackwall and whitewall presentations to touring- and performance-oriented radial series. The real decision is matching the correct size and visual style to the car's exact setup and intended use.
Which Tire Size Is Right for The 1977 Saab Saab 99
The 1977 Saab Saab 99 uses two primary tire sizes, both built for 15-inch rims and both radial in construction. 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 that is settled, the choice usually comes down to tire character, sidewall style, and how closely the tire matches the car's intended appearance and road use.
175/70R15 is a metric radial size with a 175-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 15-inch rim diameter. Compared with older Euro-metric sizing conventions, this format gives the buyer a more explicit profile number right in the size code. For the 1977 Saab Saab 99, this size appears on certain EMS applications and is offered in blackwall form through series such as Avon CR6ZZ and Vredestein Sprint Classic. It is the size to evaluate when the car specifically calls for it and the goal is a more defined metric radial fitment.
Sub-model fitment matters on the 1977 Saab Saab 99 because tire sizing is not identical across the lineup. The Base stays with one radial size, while the EMS introduces an additional 15-inch radial option, so identifying the exact version comes before comparing tires.

1977 Saab Saab 99 Base
The 1977 Saab Saab 99 Base uses the 165R15 radial size. That keeps tire selection focused on choosing among available brands, sidewall treatments, and tire series rather than sorting through multiple primary fitments.
The 1977 Saab Saab 99 EMS can use either 165R15 or 175/70R15 radial tires. That makes wheel and current vehicle setup worth confirming first, then narrowing the choice by the kind of appearance and road character you want from the car.
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 focus on the tire sizes used on the 1977 Saab Saab 99, how Base and EMS fitments differ, and how to sort through radial size, sidewall, brand, appearance, and maintenance decisions before road use.
Tire Size & Fitment
What tire size fits a 1977 Saab Saab 99?
The 1977 Saab Saab 99 uses two radial tire sizes: 165R15 and 175/70R15. Fitment depends on sub-model, with the Base using 165R15 and the EMS using 165R15 or 175/70R15, all on 15-inch rims.
The practical step is confirming whether the car is a Base or EMS and then checking which wheels are actually on the car today. On older Saabs, wheel changes over time are common, so matching the tire to the actual rim diameter and the car's current setup matters more than assuming every 99 uses the same size.
What size rim does a 1977 Saab Saab 99 use?
The tire sizes used on the 1977 Saab Saab 99 are built around a 15-inch rim diameter. That applies to both 165R15 and 175/70R15, so the key wheel measurement here is 15 inches rather than a change in diameter between sizes.
Rim diameter is only part of the fitment picture, especially on a car that may have seen replacement wheels over the years. It still helps to verify wheel width as well, because individual tire options within these sizes have their own approved rim-width ranges and should be matched to the wheel before installation.
Do all 1977 Saab Saab 99 sub-models use the same tire size?
No. The 1977 Saab Saab 99 Base uses 165R15, while the EMS can use either 165R15 or 175/70R15. That means tire fitment is not fully uniform across all versions of the car, even though both sizes share the same 15-inch rim diameter.
That distinction matters because the right starting point is the exact sub-model and current wheel setup, not the model name alone. If the car is an EMS, checking the existing tire size and wheel dimensions before choosing replacements helps avoid selecting a tire that matches the year and model but not the specific configuration.
Choosing the Right Tire
What should I consider when choosing a 165R15 tire for a 1977 Saab Saab 99?
A 165R15 tire for a 1977 Saab Saab 99 should first match the car's required size and wheel setup, then the choice can shift to tire character and appearance. This size is offered across several radial series, with blackwall, narrow whitewall, and wide whitewall options from multiple brands.
For a more traditional presentation, whitewall options can change the car's visual tone significantly, while blackwall tires keep a more understated look. It also helps to compare each tire's approved rim-width range and load specification so the selected product suits both the wheel and the kind of driving the car will actually see.
What sidewall styles are available for 1977 Saab Saab 99 tires?
The 1977 Saab Saab 99 has several sidewall presentations available, depending on size and product. In 165R15, choices include blackwall, narrow whitewall, and wide whitewall, while 175/70R15 options shown here are blackwall.
That makes sidewall choice an important part of the buying decision, especially if the car is being restored with a certain period-style look in mind. A whitewall can give the car a more formal or classic presentation, while blackwall options usually suit a cleaner and more understated appearance on a late-1970s European sedan.
What brands offer tires for the 1977 Saab Saab 99?
Tires for the 1977 Saab Saab 99 are available from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, Vredestein, and Avon. Brand availability depends on size, with 165R15 having the broadest selection and 175/70R15 offered in a smaller blackwall-only group.
Brand choice should be considered alongside size, sidewall style, and tire series rather than in isolation. Some options lean toward traditional whitewall presentation, while others keep a more European blackwall look, so the best comparison is how each tire fits the car's size requirement, wheel width, and visual direction.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Saab Saab 99?
For a period-style 1977 Saab Saab 99, the first priority is using the correct primary size for the car's exact sub-model and wheel setup. The 165R15 size offers the strongest range of traditional-looking radial choices, including blackwall, narrow whitewall, and wide whitewall versions.
A restoration-minded owner should decide whether the goal is a European-style blackwall presentation or a more custom vintage look with whitewalls. When exact originality matters, checking period photos, marque-club guidance, or other vehicle-specific references is worthwhile, because a correct size alone does not automatically confirm the historically appropriate sidewall treatment.
How does tire construction affect the appearance of a restored 1977 Saab Saab 99?
On the 1977 Saab Saab 99, the primary fitments are radial, so construction choice is not a bias-ply-versus-radial question here as it is on many older cars. The visible difference comes more from the tire's profile, sidewall treatment, and series styling than from a change in basic construction type.
That means appearance decisions usually center on whether the car should wear blackwall rubber in a more restrained European style or a whitewall treatment that shifts the visual character. Even within the same 165R15 size, those sidewall choices can make the car look more formal, more custom, or more driver-oriented.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Saab Saab 99?
Yes. A 1977 Saab Saab 99 can be affected by aftermarket wheels, changes in wheel width, suspension alterations, or body modifications just like any other older vehicle. Even when the tire size is correct on paper, those changes can alter clearance at the fender, steering, or suspension.
That is especially important on the EMS, since more than one primary size may be encountered. Checking actual rim diameter, wheel width, and space around the tire before replacement helps avoid choosing a tire that matches the model year but does not suit the car's present-day configuration.
What should I inspect before driving a 1977 Saab Saab 99 on new tires?
Before driving a 1977 Saab Saab 99 on new tires, inspect the wheels for damage, confirm the wheel dimensions match the tire, and make sure the tires are inflated properly for the intended setup. It also helps to verify that the tires clear the fenders and suspension through steering travel.
A broader road-use check is smart on any collector-era Saab. Look over suspension and steering components, recheck lug torque after installation, and watch for any signs of rubbing or uneven contact once the car is driven. Catching those issues early protects both the new tires and the rest of the car.
How should 165R15 tires on a collector 1977 Saab Saab 99 be maintained?
165R15 tires on a collector 1977 Saab Saab 99 should be kept at the proper pressure for the specific tire and vehicle setup, inspected regularly for cracking, cuts, bulges, and uneven wear, and checked for air loss if the car sits for long periods. Storage conditions also matter.
A low-use Saab often ages its tires before it wears them out, so tread depth alone should not decide roadworthiness. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber, and periodic inspections remain important even when the car is driven only occasionally.
