Mercedes-Benz 170 Tires

Mercedes-Benz 170 models in this range use three listed tire sizes: 550-16 from 1946 through 1955, 175R15 from 1949 through 1953, and 640-15 from 1949 through 1953. The 550-16 size fits 16-inch rims, while both 175R15 and 640-15 fit 15-inch rims. That means the same model name can point to different wheel diameters depending on year and configuration.

The practical takeaway is to start with the wheel on the car rather than the badge on the hood. A Mercedes-Benz 170 with 16-inch wheels belongs in the 550-16 group, while a car on 15-inch wheels falls into the 175R15 or 640-15 range. After that, compare the tire already fitted, any surviving factory paperwork, and the intended use of the car before making a final choice.

On a Mercedes-Benz 170, 550-16 is a traditional numeric bias-ply size. The 550 portion indicates a nominal section width of about 5.50 inches, and the 16 identifies the rim diameter in inches. Every listed product in this size is a bias-ply tire built for 16-inch wheels.

That makes 550-16 the size to look at when the car still carries its 16-inch wheel setup and a period-style driving feel is part of the goal. It is not interchangeable with the 15-inch sizes listed for later overlapping years. Check the wheel diameter directly and match the tire to the rim before deciding among blackwall or whitewall versions.

A 1949 Mercedes-Benz 170 can show 550-16, 175R15, and 640-15 because that year sits in the overlap between earlier 16-inch applications and later 15-inch applications. The split is driven by wheel diameter, not by one size simply replacing another across every car. Two of the listed sizes use 15-inch rims, while one uses a 16-inch rim.

That means year alone is not enough to choose a tire for a 1949 Mercedes-Benz 170. Measure the wheel, read the existing tire if it is trustworthy, and compare the car against restoration records or marque references. Once the wheel diameter is settled, the correct size range becomes much narrower and the bias-ply versus radial-style decision is easier to evaluate.

Mercedes-Benz 170 models in this range use both 16-inch and 15-inch rim diameters. The 16-inch application appears with 550-16 from 1946 through 1955, while 15-inch applications appear with 175R15 and 640-15 from 1949 through 1953. The first year where the 15-inch wheel appears in the listings is 1949.

Rim diameter is the first fitment detail to verify because it immediately separates the correct tire families. A 16-inch wheel cannot use the 15-inch sizes, and a 15-inch wheel cannot use 550-16. Check the stampings on the wheel if present, or measure carefully at the bead seat rather than across the outside edge of the rim.

A 1951 Mercedes-Benz 170 can fall into more than one listed size group, so confirmation starts with the actual wheel diameter on the car. If the car has 16-inch wheels, the listed size is 550-16. If the car has 15-inch wheels, the listed choices are 175R15 and 640-15.

Once wheel diameter is confirmed, compare the tire currently on the car against restoration records and the look you want. A buyer seeking a period bias-ply presentation will usually focus on 550-16 or 640-15 depending on wheel size, while 175R15 points to a radial-format fitment on a 15-inch wheel. Sidewall style is the final visual decision after size is settled.

Mercedes-Benz 170 tires in the listed range are available in blackwall, narrow whitewall, and wide whitewall styles. The 550-16 offerings include blackwall and wide whitewall versions, while 640-15 includes blackwall, narrow whitewall, and wide whitewall choices. That gives restorers room to match either a restrained factory-type look or a more stylized period presentation.

Sidewall style should be chosen after the size and wheel diameter are confirmed. Blackwall is usually the safest visual starting point for a sober postwar European sedan, while whitewall width becomes more of a presentation decision. For a judged restoration, compare photographs, market-specific references, and surviving cars of similar specification before settling on whitewall width.

Four brands appear in the Mercedes-Benz 170 tire offerings: Excelsior, Avon, BFGoodrich, and Firestone. The 550-16 size is represented by all four, and the 640-15 size is also offered across that same group. Within those brands, the available tires span several period-style bias-ply series and sidewall treatments.

Brand choice usually comes down to the look you want, the series construction style you prefer, and whether a certain sidewall treatment is important to the restoration. It is worth comparing the full size, wheel diameter, and sidewall combination first, then narrowing by brand. On a collector car like the Mercedes-Benz 170, the correct fit and visual character matter more than brand loyalty alone.

Mercedes-Benz 170 tire offerings include Excelsior Bias Ply, Tourist Crossply, Silvertown Classic Bias Ply, Firestone Classic Bias Ply, and Super Safety Crossply. All of the listed products for the available sizes are bias-ply tires, but the series names reflect different period-style lines, tread designs, and presentation choices within that construction type. Some series also appear with multiple sidewall options, including blackwall and whitewall versions.

That means the series decision is less about changing the basic construction technology and more about selecting the look and character that best matches the car. A Mercedes-Benz 170 restored toward factory restraint may lean toward a simpler blackwall bias-ply, while a more show-oriented presentation may favor one of the whitewall series. Confirm size and wheel diameter first, then compare the available series within that fitment.

A Mercedes-Benz 170 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, welders, and ozone-producing equipment. Tires on collector cars age more from time, environment, and static load than from mileage alone. Keeping the car clean and the tires properly inflated helps prevent flat spotting and sidewall stress during long periods of inactivity.

If the Mercedes-Benz 170 will sit for extended periods, move it occasionally or support the vehicle in a way that reduces continuous load on one contact patch. Avoid parking on bare concrete if possible, and keep petroleum products off the rubber. A simple storage routine preserves both the appearance and service life of specialty collector tires.

Tires on a Mercedes-Benz 170 should be inspected before regular driving and again after long storage periods. Look for sidewall cracking, tread separation, irregular wear, cuts, embedded debris, and any sign that the tire has gone out of shape. On a low-use collector car, age-related issues can appear long before the tread is worn down.

An annual hands-on inspection by a shop familiar with vintage tires is a sensible baseline, even if the car is driven only occasionally. If the Mercedes-Benz 170 uses bias-ply tires, pay close attention to tube condition, valve stems, and any vibration that develops after storage. Catching those issues early is far easier than dealing with a roadside failure in a collector car.

Tires on a Mercedes-Benz 170 should be replaced when they show age cracking, separation, repeated air-loss issues, impact damage, or any visible structural deterioration, even if the tread still looks usable. Collector tires often age out before they wear out. A car that sees little mileage can still be riding on rubber that is no longer trustworthy for road use.

Replacement decisions should be driven by condition and age as much as by tread depth. If the Mercedes-Benz 170 has spent years parked, have the tires removed and inspected internally as well as externally, especially on tube-type bias-ply applications. That approach helps preserve the car and avoids placing too much confidence in old rubber that merely looks presentable.

The listed Mercedes-Benz 170 sizes across 1946 to 1955 are 550-16, 175R15, and 640-15, with several bias-ply series available in the replacement market including Excelsior Bias Ply, Tourist Crossply, Silvertown Classic Bias Ply, Firestone Classic Bias Ply, and Super Safety Crossply. Because more than one size appears in the overlap years, original fitment is tied closely to wheel diameter and configuration rather than to model name alone. No single replacement series should be assumed correct for every car in the range.

For an accurate restoration, start by establishing whether the car retains its original wheels and then compare that with period photos, factory literature, and marque-club guidance. A Mercedes-Benz 170 on 16-inch wheels points toward one fitment family, while a 15-inch-wheel car belongs to another. The closer the restoration goal is to formal judging, the more important that verification becomes.

Correct tire fitment can affect both presentation value and judging outcomes on a Mercedes-Benz 170. Judges and knowledgeable buyers notice whether the wheel diameter, tire profile, sidewall style, and overall stance suit the period and configuration of the car. A mismatched rim diameter or an obviously inappropriate sidewall treatment can distract from otherwise good restoration work.

That does not mean every Mercedes-Benz 170 must wear the same tire, because the year range includes more than one valid fitment path. It does mean the chosen tire should make sense for the specific car being restored. Marque clubs, period brochures, and surviving unrestored examples are the best references when authenticity carries real weight.

Mercedes-Benz 170 tire options in the listed sizes include blackwall, narrow whitewall, and wide whitewall styles. Blackwall appears in both 550-16 and 640-15 offerings, while 640-15 also includes narrow and wide whitewall choices. That gives restorers a range from understated to more decorative period presentation.

For many Mercedes-Benz 170 restorations, blackwall is the most conservative and historically comfortable place to start. Whitewalls may suit certain presentation goals, but the width should be chosen carefully so the car still looks balanced and era-appropriate. Compare period photographs of similar cars and decide whether the restoration is aiming for factory sobriety, export-market flair, or personal preference within period style.

A Mercedes-Benz 170 can be driven on public roads when the tires are the correct size for the wheel, are in sound condition, and are paired with a vehicle that has been mechanically sorted as a whole. The listed replacement offerings for 550-16 and 640-15 are modern-manufactured vintage-style tires, which is different from relying on aged original rubber. Safe road use still depends on the entire car, not the tire alone.

Before regular driving, inspect steering, brakes, wheel bearings, alignment, and tire age in addition to tread and inflation. A Mercedes-Benz 170 is a postwar collector car with handling and braking characteristics far removed from modern traffic expectations. Drive with generous margins, avoid sustained high-speed use, and match the pace to the car's design and condition.

Before driving a Mercedes-Benz 170, check tire pressure, visible sidewall condition, valve stems, wheel fasteners, and any signs of rubbing or uneven wear. On bias-ply applications such as 550-16 and 640-15, it is also wise to pay attention to tube integrity and any vibration that suggests flat spotting or internal trouble. A quick pre-drive walkaround matters more on a low-use collector car than many owners realize.

The goal is to catch age-related issues before they become failures on the road. If the Mercedes-Benz 170 has been sitting, begin with a short, cautious drive and reassess how the tires feel once they have rolled and warmed slightly. Any pull, thump, wobble, or recurring air loss deserves immediate attention before the car is used further.

A Mercedes-Benz 170 should be driven at moderate speeds that respect both the age of the car and the construction style of the tires fitted to it. Period-style bias-ply tires do not behave like modern touring radials, and the car's chassis, steering, and braking were designed for an earlier motoring environment. Smooth, unhurried road use is a better match than sustained fast highway travel.

The sensible approach is to let the condition of the car, the condition of the tires, and the road environment set the pace. Even when the tires are new, a Mercedes-Benz 170 remains a collector automobile that rewards conservative driving. Leave extra stopping distance, slow down for crowned roads and grooves, and treat maximum speed as far less important than stability and mechanical sympathy.
