The 1974 Saab Saab 99 came from an era when Saab had fully established its reputation for practical engineering, front-wheel-drive road manners, and distinctly European design. For owners today, that makes tire choice less about chasing a broad modern substitute and more about matching the car’s original character and wheel setup. This model uses 15-inch radial fitments, with 165R15 serving as the core size and 175/70R15 also appearing on certain EMS applications. Available choices range from blackwall to narrow and wide whitewall styles, along with several classic radial series. The real decision is choosing the size and presentation that suit your exact sub-model, wheel, and restoration goals.
Which Tire Size Is Right for The 1974 Saab Saab 99
The 1974 Saab Saab 99 uses two radial tire sizes, both 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 that is settled, the choice shifts to tire profile, sidewall appearance, and the specific radial series that best matches how the car will look and be driven.
A 165R15 uses a 165-millimeter nominal section width, radial construction, and a 15-inch rim diameter. In this older Euro-metric format, the aspect ratio is not stated in the size itself and is commonly treated as an 80-series style radial. On the 1974 Saab Saab 99, this size supports a very broad selection that includes blackwall, narrow whitewall, and wide whitewall treatments from brands such as Michelin, Firestone, BFGoodrich, Coker Classic, American Classic, and Vredestein. It is the key size for owners focused on preserving the Saab’s original European radial character while still choosing among several visual styles and tire series.
A 175/70R15 is a metric radial with a 175-millimeter section width, a 70-series aspect ratio, and a 15-inch rim diameter. Compared with older Euro-metric sizing, this format states the profile directly, which helps buyers understand that it is a lower-profile radial style. For the 1974 Saab Saab 99, it appears on EMS applications and is offered here in blackwall form through Avon and Vredestein series. This size deserves a closer look when the car is an EMS and the owner wants a radial selection tied to that specific setup rather than assuming the Base-model fitment applies.
Sub-model fitment matters on the 1974 Saab Saab 99 because tire sizing is not completely uniform across the lineup. The Base stays with one radial size, while the EMS is the version that requires a closer check before selecting a tire.

1974 Saab Saab 99 Base
The 1974 Saab Saab 99 Base uses the 165R15 radial size on a 15-inch wheel. That keeps tire selection straightforward, with the main decision centered on blackwall versus whitewall appearance and the particular classic radial series that best suits the car’s intended look and use.
The 1974 Saab Saab 99 EMS can use either 165R15 or 175/70R15 radial tires, so confirming the wheel and existing setup is especially important. That makes the EMS the sub-model where profile choice, wheel compatibility, and the actual tire already on the car should be checked before moving ahead.
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 1974 Saab Saab 99 Tires for sale
Available 1974 Saab Saab 99 tire choices center on radial 15-inch fitments, with the widest selection in 165R15. Buyers can compare brands such as Michelin, Firestone, BFGoodrich, Coker Classic, American Classic, Vredestein, and Avon, along with blackwall, narrow whitewall, and wide whitewall sidewall treatments across several classic tire series.
Common questions for the 1974 Saab Saab 99 usually come down to the correct tire size by sub-model, how 165R15 differs from 175/70R15, and how to choose among the available radial styles, brands, and period-minded appearances.
Tire Size & Fitment
What tire size fits a 1974 Saab Saab 99?
The 1974 Saab Saab 99 uses two 15-inch radial tire sizes: 165R15 and 175/70R15. The Base model uses 165R15, while the EMS is associated with both 165R15 and 175/70R15, so the exact sub-model and current wheel setup matter before choosing a tire.
That means the first step is not simply picking a radial tire with a 15-inch diameter. The owner should confirm whether the car is a Base or EMS, then verify the wheels actually on the car and compare the existing tire size before replacement, especially if the Saab has been changed from its earlier setup over the years.
What size rim does a 1974 Saab Saab 99 use?
Both tire sizes used on the 1974 Saab Saab 99 are built for 15-inch rims. That applies to the 165R15 fitment and to the 175/70R15 fitment used on certain EMS applications, so rim diameter remains consistent even though the tire profile can differ.
Rim diameter is only part of the fitment picture, however. Before selecting a tire, it still makes sense to confirm the wheel width and the actual wheels on the car, because some available 165R15 products cover different rim-width ranges and the EMS may need a closer look if wheel or suspension changes have been made.
Do all 1974 Saab Saab 99 sub-models use the same tire size?
No. The 1974 Saab Saab 99 Base uses 165R15, while the EMS is associated with both 165R15 and 175/70R15. Both are radial sizes for 15-inch wheels, but the EMS is the sub-model where tire choice is less straightforward.
That difference matters because a buyer should not assume every Saab 99 from 1974 takes the same tire just because the wheel diameter matches. On an EMS, checking the exact wheel and tire combination already on the car can prevent confusion and helps narrow the selection to the right profile and product style.
Choosing the Right Tire
What should I consider when choosing a 165R15 tire for a 1974 Saab Saab 99?
Start with the fact that 165R15 is the core fitment for the 1974 Saab Saab 99 and the sole size used on the Base model. Within that size, choices vary by radial series, sidewall treatment, rim-width specification, load specification where stated, and whether the goal is a blackwall European look or a whitewall presentation.
A practical selection comes from matching the tire to the car’s actual use and appearance plan. Some owners want a period-style blackwall from Michelin, Firestone, or Vredestein, while others prefer a narrow or wide whitewall from American Classic, BFGoodrich, or Coker Classic, so wheel width and visual style should be reviewed together.
What sidewall styles are available for 1974 Saab Saab 99 tires?
The 1974 Saab Saab 99 has meaningful sidewall variety in 165R15. Available styles include blackwall, narrow whitewall, and wide whitewall, while the 175/70R15 choices shown here are blackwall tires. That gives buyers a broader appearance range in the main 165R15 fitment than in the EMS-specific lower-profile option.
Sidewall style changes the car’s presentation more than many owners expect. A blackwall usually preserves a restrained European look, while narrow and wide whitewalls create a more restoration-oriented visual statement, so the right choice depends on whether the Saab is being kept understated, displayed, or tailored to a personal period-inspired style.
What brands offer tires for the 1974 Saab Saab 99?
The 1974 Saab Saab 99 is served by several brands across its two tire sizes. In 165R15, choices include Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein. In 175/70R15, the available brands are Avon and Vredestein, both in blackwall radial form.
Brand choice should be considered alongside size, series, and sidewall style rather than as a stand-alone decision. Some brands concentrate on traditional blackwall European-style radials, while others add narrow or wide whitewall versions, so the best comparison is the one that keeps the tire visually and dimensionally appropriate for the specific Saab 99 configuration.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Saab Saab 99?
A period-style 1974 Saab Saab 99 usually starts with the correct sub-model fitment and wheel diameter, then narrows to a radial that suits the car’s character. For many cars, that means 165R15, especially on the Base, while an EMS owner should confirm whether the car is set up for 165R15 or 175/70R15 before focusing on appearance.
Once the size is confirmed, the visual decision becomes blackwall versus whitewall and the type of classic radial series desired. Owners pursuing exact originality should compare the chosen tire against marque-specific historical references, because a period-style option can look right on the car without necessarily matching every detail of an earlier delivery configuration.
How does tire construction affect the appearance of a restored 1974 Saab Saab 99?
On the 1974 Saab Saab 99, the primary fitments are radial, so the construction itself already aligns with the car’s era and European road-car character. Appearance differences come less from choosing between bias-ply and radial and more from choosing the tire’s profile format, sidewall treatment, and the overall styling of the radial series.
That means a restored Saab 99 can look noticeably different even when the tire size is correct. A blackwall 165R15 tends to keep a clean, understated presentation, while narrow or wide whitewalls create a very different impression, and the EMS-specific 175/70R15 can also change the visual stance because it is a stated-profile metric radial.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Saab Saab 99?
Yes. Even though the 1974 Saab Saab 99 uses 15-inch radial fitments, aftermarket wheels, altered wheel widths, suspension changes, or body clearance differences can affect which tire works best on the car. That matters most on the EMS, where both 165R15 and 175/70R15 enter the conversation.
A modified Saab should be checked as an individual car rather than treated like an untouched factory example. Wheel width, tire-to-fender clearance, steering clearance, and the actual tire size already mounted are all worth confirming before replacement, especially if the car sits lower, uses non-stock wheels, or has seen earlier fitment changes.
What should I inspect before driving a 1974 Saab Saab 99 on new tires?
Before putting a 1974 Saab Saab 99 back into regular road use, inspect the wheel condition, confirm the chosen tire size matches the car’s setup, and make sure each tire is properly inflated. It is also wise to look over the valve stems, check for any rubbing at full steering lock, and verify even seating on the rim.
A collector-era car often needs more than a quick tire swap before it is truly road-ready. Brake condition, suspension wear, alignment, and the age or condition of the spare should all be reviewed, because a fresh set of tires will only deliver proper service if the rest of the Saab’s running gear is equally sound.
How should 165R15 tires on a collector 1974 Saab Saab 99 be maintained?
165R15 tires on a collector 1974 Saab Saab 99 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Look for cracking, bulges, cuts, irregular tread wear, or signs of slow air loss, and keep the car away from prolonged heat, direct sunlight, excess moisture, and ozone sources when stored.
Low-use collector cars can age tires out long before they wear them out. Occasional movement to avoid long-term flat spotting, periodic inspection of wheel condition, and attention to alignment or suspension issues will help protect the tires and preserve the way the Saab feels on the road when it is brought back into service.
