1955 Mercedes-Benz Tire Fitment Guide

1955 Mercedes-Benz vehicles use thirteen sizes across five model lines. The 170 uses 550-16; the 180 uses 640-13 and 700-13; the 190 uses 700-13 and 185R13; the 220 uses 175R13, 6.70-13, 175R15, and 640-15; and the 300 uses 205R15, 710-15, 760-15, 185R15, and 670-15. Rim diameters span 13, 15, and 16 inches, so the lineup does not share one universal wheel size.

That means year and make alone are not enough for a confident tire choice on a 1955 Mercedes-Benz. Start by identifying the exact model, then verify whether the car is on 13-inch, 15-inch, or 16-inch wheels before comparing construction type, sidewall style, or brand. Where rim-width guidance is available, it also differs by size, which is another reason to match the tire to the specific wheel rather than assume interchangeability across the full Mercedes range.

On a 1955 Mercedes-Benz, 550-16 is an older numeric bias-ply size. The first number indicates a nominal section width of 5.50 inches, and the second number indicates a 16-inch wheel diameter. In the 1955 Mercedes-Benz range, that size belongs to the 170 and appears only in bias-ply form within the available product mix.

A buyer looking at a 1955 Mercedes-Benz 170 should read 550-16 as a traditional inch-based fitment rather than a modern metric radial code. That matters because replacement choices in this size center on period-style construction and appearance, including blackwall and wide whitewall versions. Matching the actual 16-inch wheel and staying within the listed rim-width range for the chosen product is the right next step before selecting a tire.

On a 1955 Mercedes-Benz, 185R13 is a euro-metric radial size. The 185 identifies the tire's section width in millimeters, the R indicates radial construction, and the 13 is the wheel diameter in inches. In this 1955 Mercedes-Benz application, 185R13 is used on the 190 and appears in Michelin form as a tubeless blackwall radial with an H speed rating.

That code tells you the tire belongs to a more modern radial sizing convention than the older 700-13 numeric bias-ply alternative also used in the 1955 Mercedes-Benz 190 range. Owners comparing those two are not just choosing a number on the sidewall; they are choosing between two different construction families and two different visual characters. Confirming that the car is on a 13-inch wheel remains the first fitment check.

No, 1955 Mercedes-Benz models do not use the same tire size. The smallest cars in the range use 13-inch or 16-inch fitments depending on model, while the larger 220 and 300 series can appear with multiple sizes and, in some cases, both bias-ply and radial alternatives. Even within one model line, there can be more than one valid size path.

The practical takeaway is that a 1955 Mercedes-Benz owner should identify the model before doing anything else. A 170, 180, 190, 220, and 300 do not share one universal fitment, and the 220 especially needs wheel-diameter confirmation because both 13-inch and 15-inch sizes appear in its range. Once the model and wheel diameter are settled, narrowing the tire choice becomes much more straightforward.

For a 1955 Mercedes-Benz 190, the choice between 700-13 and 185R13 is mainly a choice between bias-ply and radial construction on the same 13-inch wheel diameter. The 700-13 option is a traditional numeric bias-ply available here as a Firestone wide whitewall, while 185R13 is a Michelin blackwall radial with an H speed rating. They serve different ownership priorities more than different model applications.

A buyer restoring a 1955 Mercedes-Benz 190 with a strong emphasis on period presentation will usually lean toward the bias-ply route, while a driver who wants the character of a classic European radial will likely look harder at 185R13. Either way, the right decision starts with the intended use of the car rather than assuming one is universally correct. Sidewall appearance may also help break the tie if originality goals are specific.

1955 Mercedes-Benz tires are available in a broad mix of sidewall styles depending on size. Blackwall, wide whitewall, narrow whitewall, and redline all appear in the product range, but they are not offered in every size. Smaller numeric sizes such as 550-16 and 640-13 lean toward blackwall and wide whitewall options, while some 15-inch sizes on the 300 add narrow whitewall or redline radial choices.

For most 1955 Mercedes-Benz restorations, blackwall and tasteful whitewall treatments align more naturally with the era than a redline, especially on formal sedans. The deciding factor is often the specific model and the look you are trying to recreate rather than simple fitment. If show authenticity matters, verify the sidewall style against period photos, sales literature, or a marque specialist before finalizing the tire choice.

Brands appearing in the 1955 Mercedes-Benz tire range include Excelsior, Avon, BFGoodrich, Firestone, Michelin, Phoenix, Coker Classic, Universal Vintage Tire, and US Royal. Brand choice depends heavily on size: 550-16 spans several makers, 205R15 is offered by Phoenix and Avon, 185R15 includes Coker Classic and Michelin, and larger bias-ply 15-inch sizes on the 300 pull in several traditional American vintage-tire brands.

That variety gives a 1955 Mercedes-Benz owner room to choose not only a size and construction, but also a particular visual or driving character within that size. Some brands focus on classic American-style bias-ply looks, while Michelin and Avon cover more European-flavored radial applications in the Mercedes range. The right comparison is size-specific, since one brand's strengths in a 15-inch radial do not automatically apply to a 13-inch or 16-inch bias-ply fitment.

Rim-width guidance varies by size on 1955 Mercedes-Benz tires. Available ranges include 3.25 to 4.00 inches for 550-16, 4.00 to 4.50 for 640-13, 4.00 to 5.00 for 700-13, 4.00 to 4.50 or 4.50 to 5.00 depending on the 640-15 product, 5.50 to 6.00 for 205R15, 5.00 to 5.50 for 710-15, 5.50 to 6.00 for 760-15, 5.00 to 6.50 or 4.5 to 6 on 185R15 products, and 4.50 to 5.00 or 5.00 to 6.00 on 670-15 products.

Those ranges show why the wheel itself matters just as much as the sidewall code on a 1955 Mercedes-Benz. Some sizes are offered in products with more than one approved rim-width range, so it is wise to match the actual wheel width to the exact tire you are considering instead of treating all versions of a size as identical. That step becomes especially important on larger 15-inch fitments where both narrower and wider wheel pairings appear.

Tube requirements on 1955 Mercedes-Benz tires depend on the exact size and product. The listed 185R13 and 185R15 radial products are tubeless, marked TL, while many bias-ply products are presented without a tube designation in the size line. Because that marking is not consistent across the full 1955 Mercedes-Benz range, tube use should be confirmed against the specific tire and wheel combination you plan to run.

That matters because tube choice is influenced not only by the tire, but also by the wheel's design and condition. A 1955 Mercedes-Benz owner using a tubeless radial on an appropriate wheel can approach the setup differently from someone mounting a traditional bias-ply tire on an older rim. Before installation, confirm the wheel's intended tube or tubeless use, inspect the valve-stem area, and match any tube decision to the product's actual sidewall marking.

A 1955 Mercedes-Benz should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate sidewall aging. Keep the tires properly inflated, roll the car periodically if possible, and avoid leaving one contact patch loaded in the same spot for months at a time. Bias-ply tires tend to flat-spot more readily during static storage than radials, so long idle periods deserve extra attention.

Practical storage habits make a noticeable difference on a collector Mercedes that may sit between events or seasonal drives. Clean floors, stable temperature, and a simple routine of movement or support stands can help reduce stress on both the tires and suspension. If the car is stored for an extended period, inspect for cracking and pressure loss before the first drive rather than assuming the tires are ready just because tread depth still looks good.

Tires on a 1955 Mercedes-Benz are usually judged more by age than by miles. A good rule is to begin evaluating them closely once they are around five to seven years old and to treat roughly ten years as a point where replacement deserves serious consideration, even on a lightly used collector car. The DOT date code on the tire helps establish age, which is often more revealing than outward tread wear on hobby-driven vehicles.

That age-based approach is especially important for a 1955 Mercedes-Benz because these cars are often driven infrequently and stored for long periods. A tire can look presentable yet still harden, crack, or lose confidence on the road simply from time and exposure. If the car has an older spare, include it in the same age review, since a long trip can turn a forgotten spare into the tire you depend on most.

Tires on a 1955 Mercedes-Benz should be inspected before every drive, and given a more deliberate check before any extended outing. Look for sidewall cracking, cuts, bulges, unusual tread wear, and pressure loss, and pay attention to whether the car has been sitting long enough for temporary flat-spotting to develop. If the setup uses tubes, valve stems and any signs of slow leakage deserve the same level of attention as the tread and sidewalls.

A brief inspection routine is one of the easiest ways to avoid interrupting a drive in an older Mercedes. Collector cars often reveal tire issues after storage, during the first few miles, or when highway heat builds in a casing that has not been exercised recently. Catching a pressure problem, cracked valve stem, or fresh sidewall blemish in the garage is far better than finding it after the car is loaded for a tour.

A 1955 Mercedes-Benz 170 would have been associated with a bias-ply tire in the 550-16 range, which fits the period and the car's traditional engineering background. Within the available choices, 550-16 appears only as a bias-ply size, which aligns with what a mid-1950s Mercedes of that lineage would be expected to use. Original-equipment brand selection can vary by market and delivery history, so construction type and size are the more reliable starting points.

For restoration work, the most important step is to preserve the correct relationship between the 170 and its 16-inch bias-ply fitment rather than assume a modern radial substitute is automatically equivalent. Sidewall treatment then becomes part of the authenticity decision, especially if the car is being prepared for judging or period presentation. If the car has an unusual export-market history, a Mercedes marque club can help refine the final sidewall and presentation details.

Correct tire fitment matters on a 1955 Mercedes-Benz because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A car shown for originality can lose credibility if it wears a visibly modern radial where a period bias-ply presentation is expected, or if the sidewall treatment clashes with the era and market position of the model. Even among valid fitments, the visual impression of the tire can change how authentic the whole car feels.

That does not mean every 1955 Mercedes-Benz must use the same type of tire for every purpose, but it does mean the intended role of the car should guide the choice. A tour car and a concours car may reasonably wear different constructions, while still staying within known size families for the model. Event-specific standards vary, so serious show preparation should include checking with the hosting club or a Mercedes specialist before finalizing tires.

For a 1955 Mercedes-Benz 300 using 185R15, Michelin XVS and Coker Classic radial offerings differ in sidewall presentation, speed rating range, and approved rim widths. Michelin appears in blackwall and narrow whitewall form with H and V-rated versions, while Coker Classic appears as a redline radial with a listed load figure of 1355 pounds at 35 psi. Michelin products list rim-width ranges from 4.5 to 6 inches or 5.00 to 6.50 inches, while the Coker Classic version lists 5.00 to 6.50 inches.

A restorer choosing between them should think first about the visual target for the car and second about how the car will be driven. The Michelin options lean toward a European radial presentation with more than one speed-rating choice, while the Coker Classic redline creates a distinctly different appearance despite sharing the same base size. Wheel width should be checked against the exact version being considered, since the approved ranges are not identical across the products.

1955 Mercedes-Benz tires can be suitable for highway driving when the tire size, construction, age, and condition all match the intended use. The radial options in this range include H-rated products at 130 mph and V-rated products at 149 mph in certain sizes, while bias-ply offerings are more about period construction than posted speed-letter comparisons. On many mid-1950s Mercedes, the car's own braking, steering, suspension, and maintenance condition may matter as much as the tire itself at normal highway speeds.

For real-world use, the safest approach is to match the tire to how the 1955 Mercedes-Benz will actually be driven rather than selecting by appearance alone. A fresh, properly mounted tire in the correct size is only part of the equation; wheel condition, alignment, and mechanical health also shape confidence at speed. Before any sustained highway outing, make sure the tires are correctly inflated, evenly wearing, and free from age-related cracking or bulging.

Inflation pressure on a 1955 Mercedes-Benz depends on the exact tire size and the specific product chosen. Several available products list rated load and pressure pairings, such as 840 pounds at 32 psi on one 550-16, 1045 at 32 psi on 640-13, 1270 at 32 psi on 700-13, 1190 at 32 psi on some 640-15 tires, 1609 at 34 psi on 205R15, 1550 at 32 psi on 710-15, 1710 at 32 psi on some 760-15 tires, and 1355 at 35 psi on one 185R15 radial.

Those figures are tire ratings, not universal set-it-and-forget-it running pressures for every 1955 Mercedes-Benz. Use the factory owner's manual or marque literature for the car's starting pressure recommendations, then compare that guidance with the tire manufacturer's limits for the exact reproduction or radial product you are using. Pressure should never be transferred from one size to another simply because the tires happen to share a wheel diameter.

Before a longer drive in a 1955 Mercedes-Benz, inspect each tire for visible cracking, cuts, bulges, irregular wear, and proper inflation, and include the spare in the same check. If the car uses a tube-type setup, examine valve stems and be alert for slow leaks that may not show up on a short local outing. Tire age is worth checking as well, especially on collector cars that may have seen little mileage over many years.

That tire inspection should be part of a broader pre-trip routine appropriate to a mid-1950s Mercedes rather than an isolated step. Wheel security, brakes, steering feel, fluid levels, and lights all deserve attention before the car is asked to sustain speed and heat for an extended period. A well-prepared 1955 Mercedes-Benz is far more enjoyable to drive, and tire condition is one of the simplest early warnings that something needs attention before the trip begins.
