The 1948 Mercedes-Benz 170 comes from the immediate postwar period, when durable engineering and conservative styling mattered more than excess, and surviving examples today are often preserved with a strong eye toward authenticity. On this model, the key tire decision starts with its 550-16 bias-ply fitment on a 16-inch rim, a sizing format that reflects the car’s era. Within that size, there is still room to choose among blackwall and wide whitewall presentations, along with period-style offerings from Excelsior, Avon, BFGoodrich, and Firestone. The right choice depends on whether the car is being kept close to its traditional appearance or prepared for careful road use with proper wheel compatibility in mind.
Which Tire Size Is Right for The 1948 Mercedes-Benz 170
The 1948 Mercedes-Benz 170 uses one primary tire size: 550-16, a bias-ply fitment for a 16-inch rim. That same size is used across the covered 170 V, Va & Vb sub-models, so the main decision is not between multiple primary sizes but between sidewall style, tire series, brand, and how closely the tire’s look and construction match the car’s intended restoration or driving use.
A 550-16 numeric bias-ply size uses a traditional older sizing system in which the 5.50 figure refers to nominal section width in inches, while 16 identifies the rim diameter. For a 1948 Mercedes-Benz 170, that means a period-appropriate bias-ply construction that suits the car’s original-era wheel and overall character. Available choices include blackwall and wide whitewall styles, with tire series such as Excelsior Bias Ply, Tourist Crossply, Silvertown Classic Bias Ply, and Firestone Classic Bias Ply. Choosing within 550-16 usually comes down to appearance goals, rim-width compatibility, and whether the car is being restored for traditional presentation or driven more regularly.
Fitment is straightforward across the covered 1948 Mercedes-Benz 170 sub-models, because they share the same primary tire size and construction. Checking the exact sub-model still helps confirm that the car remains on the expected wheel and tire setup before choosing among the available period-style tire options.

1948 Mercedes-Benz 170 V, Va & Vb
The 1948 Mercedes-Benz 170 V, Va & Vb uses the same 550-16 bias-ply tire fitment, keeping selection centered on one traditional size rather than multiple configurations. That makes it easier to focus on sidewall appearance, tire series, and wheel compatibility when choosing a replacement for restoration-minded use or careful road driving.
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 1948 Mercedes-Benz 170 Tires for Sale
Available 550-16 choices span Excelsior, Avon, BFGoodrich, and Firestone, with both blackwall and wide whitewall presentations. The product grid is most useful for comparing traditional bias-ply series, sidewall appearance, rim-width specifications where stated, and related load or weight details.
Owners of a 1948 Mercedes-Benz 170 usually want clarity on 550-16 sizing, 16-inch rim fitment, bias-ply construction, restoration-oriented appearance, and what to inspect before putting a collector-era car back on the road.
Tire Size & Fitment
What tire size fits a 1948 Mercedes-Benz 170?
The 1948 Mercedes-Benz 170 uses a 550-16 tire size. This is a numeric bias-ply size on a 16-inch rim, and it applies to the covered 170 V, Va & Vb sub-models as the primary fitment.
That means the first step is matching the car to a true 550-16 tire rather than trying to translate it into a different primary size. On a collector vehicle, it is also smart to confirm that the wheels on the car are still the correct diameter and width, especially if the car has had past restoration work or wheel changes.
What size rim does a 1948 Mercedes-Benz 170 use?
The 1948 Mercedes-Benz 170 uses a 16-inch rim with its 550-16 tire size. Product offerings in this fitment also show traditional narrow wheel compatibility, including examples intended for 3.25- to 4.00-inch rim widths.
Rim diameter is the non-negotiable starting point, because a 550-16 tire belongs on a 16-inch wheel. Before choosing among available tires, inspect the actual wheel on the car for diameter, width, and condition so the replacement matches the wheel hardware and preserves proper clearance on a restored or regularly driven 170.
Does the 1948 Mercedes-Benz 170 V, Va & Vb use the same tire size?
Yes. The covered 1948 Mercedes-Benz 170 V, Va & Vb sub-models share the same 550-16 bias-ply tire size. That keeps the fitment question simple, because the sub-model distinction does not introduce a second primary tire size here.
With size settled, the real choice moves to tire presentation and product details. A buyer can compare blackwall versus wide whitewall styling, different tire series, and wheel-width compatibility without needing to sort through multiple original fitment sizes for those covered 170 variants.
Choosing the Right Tire
What should I consider when choosing a 550-16 tire for a 1948 Mercedes-Benz 170?
Start with the correct size and construction: 550-16 bias-ply on a 16-inch rim. From there, compare sidewall style, tire series, brand, rim-width compatibility where stated, and product details such as load information or tire weight when those specifications matter to your intended use.
A restoration-minded car may call for a more traditional visual presentation, while a road-driven car may push attention toward wheel compatibility and overall condition. The best approach is to match the tire to the car’s actual wheel setup and to the way the Mercedes-Benz 170 will be displayed, toured, or maintained.
What sidewall styles are available for 1948 Mercedes-Benz 170 tires?
The available 550-16 tires for a 1948 Mercedes-Benz 170 include both blackwall and wide whitewall sidewall styles. That gives owners a clear appearance choice while staying within the correct period-style size and bias-ply construction for the car.
Blackwall tires usually suit a more restrained, utilitarian, or European presentation, while wide whitewalls create a more decorative vintage look. Since sidewall style changes the visual character of the car more than the fitment itself, many buyers choose this detail based on restoration goals, show presentation, and personal taste.
What brands offer tires for the 1948 Mercedes-Benz 170?
Tires in 550-16 for the 1948 Mercedes-Benz 170 are available from Excelsior, Avon, BFGoodrich, and Firestone. The available series include Excelsior Bias Ply, Tourist Crossply, Silvertown Classic Bias Ply, and Firestone Classic Bias Ply.
Brand choice is best used as one part of a broader comparison rather than the only decision point. It helps to look at sidewall style, tire series character, rim-width specification where stated, and whether the look of the tire supports a more understated postwar presentation or a brighter restoration-oriented appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1948 Mercedes-Benz 170?
A period-style 1948 Mercedes-Benz 170 starts with the correct 550-16 bias-ply size on a 16-inch rim. That keeps the car in the traditional sizing and construction family associated with its postwar character, while still allowing a choice among several brands and series within that fitment.
From there, the visual direction matters most. Blackwall tires usually preserve a restrained, formal look, while wide whitewalls create a stronger show-oriented statement. If exact historical originality is important, compare the tire choice against marque references, period photos, or restoration records rather than assuming any current sidewall treatment is exact for every 170.
How does tire construction affect the appearance of a restored 1948 Mercedes-Benz 170?
On a restored 1948 Mercedes-Benz 170, bias-ply construction helps preserve the traditional stance and visual character expected from a late-1940s car. Since 550-16 is offered here in bias-ply form, the available tires stay aligned with the older construction style associated with the car’s original era.
Appearance is not only about sidewall color or whitewall width; the tire’s construction style also shapes how authentic the finished car looks. For owners focused on a restoration-oriented presentation, staying with the correct numeric bias-ply fitment usually supports the overall period impression better than chasing a modernized look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1948 Mercedes-Benz 170?
Yes. Even though the primary size is 550-16, modifications can change whether a tire remains appropriate for the car’s actual setup. Wheel swaps, altered rim widths, suspension changes, brake conversions, or bodywork differences can all affect fitment on a 1948 Mercedes-Benz 170.
That is why the wheel on the car should be measured before replacing tires, especially on an older vehicle with an unknown history. Checking wheel diameter, width, steering clearance, and fender room helps confirm that the intended 550-16 tire still suits the car as it sits today rather than as it left the factory era.
What should I inspect before driving a 1948 Mercedes-Benz 170 on new tires?
Inspect the wheels, valve hardware, lug seating surfaces, and overall wheel condition before mounting new 550-16 tires. It also helps to look over steering and suspension components, since looseness, wear, or alignment issues can affect how a collector-era Mercedes-Benz 170 behaves once fresh tires are installed.
After installation, keep an eye on pressure, initial air retention, and any signs of rubbing or uneven contact. A cautious road test is worthwhile on a car of this age, because old suspension bushings, stored-for-years chassis components, or wheel damage can show up only after the car returns to regular movement.
How should 550-16 tires on a collector 1948 Mercedes-Benz 170 be maintained?
Collector-car tires in 550-16 should be maintained with regular pressure checks, visual inspections, and attention to age-related deterioration. On a 1948 Mercedes-Benz 170 that may spend long periods parked, sidewall cracking, flat spotting, air loss, cuts, and bulges deserve as much attention as tread depth.
Storage conditions matter too. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires between drives. Before any longer outing, inspect each tire closely and confirm the wheels and tires still feel stable and secure, especially if the car is driven only occasionally.
