The 1956 Saab Saab 92 comes from Saab’s early postwar years, when the brand’s small, aerodynamic cars were shaped as much by engineering efficiency as by style. For enthusiasts and restorers, that makes tire choice part of the car’s character, not just a maintenance item. This model is associated with both a 500-15 bias-ply fitment and a 135R15 radial fitment, both on 15-inch rims. That opens the door to different approaches, from traditional bias-ply presentation to narrow blackwall radial options from Michelin and Firestone. The right choice depends on whether the priority is period-style appearance, road manners, or staying close to the car’s original visual character.
Which Tire Size Is Right for The 1956 Saab Saab 92
The 1956 Saab Saab 92 uses two tire sizes, and the key difference is construction rather than wheel diameter, since both fit 15-inch rims. The Saab 92 B is associated with both 135R15 radial and 500-15 bias-ply tires, so the real decision is whether to keep a more traditional bias-ply look and feel or move toward a narrow radial setup with the same basic rim diameter.
135R15 is a narrow Euro-metric radial size in which 135 indicates nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1956 Saab Saab 92, this size offers a distinctly European radial format that suits the car’s compact proportions and 15-inch wheels. Available choices include Michelin and Firestone blackwall tires in series such as Michelin X M+S 89, Michelin ZX, and F560 Radial. This size is worth considering when the goal is a narrow radial presentation and a product selection rooted in classic small-car radial sizing.
500-15 is a numeric bias-ply size in which the leading number represents an approximate 5.00-inch nominal section width and the final number identifies a 15-inch rim. For the 1956 Saab Saab 92, it represents the traditional bias-ply fitment path and a more period-style construction choice. Available products include BFGoodrich Silvertown Classic Bias Ply options in blackwall and 2.00 inch whitewall form, along with a Firestone Dirt Track bias-ply offering. This size deserves a closer look when maintaining a vintage visual impression matters as much as simply matching rim diameter.
Sub-model fitment is straightforward here because the covered Saab 92 B is associated with the same two 15-inch tire sizes already tied to the 1956 Saab Saab 92. Checking the exact sub-model still matters, since the main decision is construction choice between radial and bias-ply rather than a different wheel diameter.

1956 Saab Saab 92 B
The 1956 Saab Saab 92 B is associated with both 135R15 radial and 500-15 bias-ply tires on 15-inch wheels. That gives owners two distinct directions to evaluate, with radial selection centered on narrow blackwall classic radials and bias-ply selection focused more on traditional appearance and period-style presentation.
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.

Tire Size & Fitment
What tire size fits a 1956 Saab Saab 92?
The 1956 Saab Saab 92 is associated with two tire sizes: 135R15 in radial construction and 500-15 in bias-ply construction. Both sizes use a 15-inch rim, and the Saab 92 B sub-model is tied to both of these fitment paths rather than to a different wheel diameter.
That means the first decision is not simply wheel size, but which construction approach suits the car and its intended use. A 500-15 bias-ply choice leans toward a more traditional presentation, while 135R15 points to a narrow classic radial. The actual wheel on the car should still be checked for width and condition before making a final selection.
What size rim does a 1956 Saab Saab 92 use?
The tire sizes associated with the 1956 Saab Saab 92 both use a 15-inch rim diameter. That applies to the 135R15 radial fitment and the 500-15 bias-ply fitment, so the vehicle stays within one wheel diameter even though the construction types differ.
Rim diameter is only part of the fitment picture on a small vintage Saab. Wheel width should also be confirmed, especially if the car has replacement wheels or if the owner is moving from bias-ply to radial construction. A 15-inch wheel does not automatically make every 15-inch tire suitable, so width, clearance, and overall setup still deserve attention.
Does the 1956 Saab Saab 92 B use the same tire size?
The 1956 Saab Saab 92 B is associated with the same two tire sizes used on this vehicle line: 135R15 in radial form and 500-15 in bias-ply form. There is no separate rim diameter attached to the 92 B, since both sizes remain 15-inch fitments.
That makes sub-model identification less about finding a different size and more about confirming how the car is equipped today. A restored Saab 92 B may be running a traditional bias-ply setup, while another may already be on narrow radials. Looking at the existing wheel width and the owner’s appearance goals helps narrow the choice between the two constructions.
Choosing the Right Tire
What should I consider when choosing a tire for a 1956 Saab Saab 92?
Start with the two recognized fitment paths for the 1956 Saab Saab 92: 500-15 bias-ply and 135R15 radial, both on 15-inch rims. The main choice is whether the car should keep a more traditional bias-ply presentation or use a narrow radial format that still suits the Saab’s compact proportions.
From there, compare wheel width, construction type, and the kind of use the car sees. Product details also matter, including sidewall style, tire series, and load figures where they are stated. A lightly driven restoration may prioritize appearance, while a car that sees more regular road time may lead the owner to look more closely at radial options.
What sidewall styles are available for 1956 Saab Saab 92 tires?
The available sidewall styles for the 1956 Saab Saab 92 include blackwall choices in both 135R15 radial and 500-15 bias-ply sizes, plus a 2.00 inch wide whitewall in the 500-15 bias-ply range. That means sidewall appearance can be part of the decision without changing the 15-inch wheel diameter.
A blackwall tire usually gives the car a simpler, more restrained small-European look, while a wide whitewall shifts the visual tone toward a more decorative period-style presentation. Sidewall style should be chosen after the correct size and construction are settled, since the radial and bias-ply options create different visual and driving-character impressions even before appearance details are considered.
What brands offer tires for the 1956 Saab Saab 92?
Tires for the 1956 Saab Saab 92 are available from Michelin, Firestone, and BFGoodrich. Michelin and Firestone appear in the 135R15 radial category, while BFGoodrich and Firestone appear in the 500-15 bias-ply category across different series and sidewall treatments.
Brand is only one part of the decision on a vintage Saab. It helps to compare each offering by construction, sidewall style, tire series, and any stated rim-width or load details rather than choosing by name alone. On a car like the Saab 92, the better question is usually which tire best matches the car’s appearance goal and wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 1956 Saab Saab 92?
For a period-style 1956 Saab Saab 92, the 500-15 bias-ply size is the most traditional-looking starting point because it keeps the vintage numeric sizing format and bias-ply construction associated with early collector-car presentation. Blackwall and 2.00 inch wide whitewall versions are both available within that size.
The final appearance choice depends on how strictly the restoration is being interpreted and how the car is meant to be shown or driven. Owners seeking the closest visual tie to a mid-1950s tire presentation often begin with bias-ply construction, while those balancing vintage style with a radial format may still prefer the narrow 135R15 size after checking wheel suitability.
How does tire construction affect the appearance of a restored 1956 Saab Saab 92?
Tire construction changes more than ride behavior on a restored 1956 Saab Saab 92; it also changes the car’s stance and visual character. A 500-15 bias-ply tire gives the car a more traditional collector-car look, while a 135R15 radial presents a narrower classic European radial appearance in blackwall form.
That difference matters on a small, early Saab because the tires are visually prominent against the body’s rounded shape and modest scale. Restoration-minded owners should decide whether the goal is a vintage bias-ply impression or a classic radial look before focusing on brand and sidewall details. Checking period photos and marque-specific references can help when originality is especially important.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1956 Saab Saab 92?
Yes, modifications can affect tire fitment on a 1956 Saab Saab 92 even when the tire size appears correct. Changes such as replacement wheels, altered wheel width, suspension work, ride-height changes, or body repairs can influence whether a 135R15 radial or 500-15 bias-ply setup works as intended on the car.
A vintage Saab has less margin for casual tire substitution than a larger domestic car, so the actual wheel and chassis setup should be checked before installation. Steering clearance, fender room, and the condition of suspension components all matter. That is especially true when moving between bias-ply and radial construction, since the wheel on the car may not match the intended tire.
What should I inspect before driving a 1956 Saab Saab 92 on new tires?
Before driving a 1956 Saab Saab 92 on new tires, inspect the wheels for correct diameter, width, and overall condition, then confirm that the tires are seated properly and inflated to the pressure appropriate for the tire itself. It also helps to look closely at valve stems, wheel hardware, and basic brake and suspension condition.
A short, careful initial drive is a smart way to check for rubbing, steering pull, vibration, or any sign that clearance is tighter than expected. Early collector cars can reveal setup issues only once they are rolling and turning under load. Rechecking pressure after the first drive and watching for any unusual wear helps catch fitment problems early.
How should tires on a collector 1956 Saab Saab 92 be maintained?
Tires on a collector 1956 Saab Saab 92 should be kept clean, properly inflated, and inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss. Because these cars are often driven infrequently, age and storage conditions can matter just as much as tread depth when judging whether the tires remain roadworthy.
Storage habits make a real difference on a low-use vintage Saab. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the rubber over time. It is also wise to inspect the tires before any longer outing rather than assuming they are ready because the car has been parked indoors and driven only occasionally.
