1960 Mercedes-Benz 180 Tires

The 1960 Mercedes-Benz 180 uses two primary tire sizes: 640-13 and 700-13. Both are vintage numeric bias-ply sizes built for 13-inch rims, so the car does not have a single universal fitment across every setup represented here.

The practical question is which of those two sizes your car is actually using now. Checking the existing tire size, the wheel width, and the overall wheel-and-tire setup is especially important before replacing tires, because both sizes share the same rim diameter but do not represent the same fitment choice.

The primary tire fitments for a 1960 Mercedes-Benz 180 are built around a 13-inch rim diameter. Both 640-13 and 700-13 use that same 13-inch wheel diameter, even though they represent different bias-ply tire sizes.

That means wheel diameter is consistent, but size selection still matters. It is wise to confirm the actual wheel width on the car, especially if the wheels may have been changed over the years, because the available products for these sizes do not share exactly the same rim-width specification.

On a 1960 Mercedes-Benz 180, 640-13 is a numeric bias-ply tire size. The 640 refers to an approximate 6.40-inch nominal section width, and the 13 refers to the rim diameter in inches.

This older sizing format does not read like a modern metric radial size, so it helps to think of it as a period tire measurement rather than a current passenger-car code. Anyone moving from 640-13 to a radial equivalent should also compare wheel compatibility and vehicle clearance instead of relying on the naming convention alone.

For the 1960 Mercedes-Benz 180, 640-13 is a bias-ply primary tire size. It is one of the original-style fitment types used on this car and keeps the vintage numeric sizing format associated with the period.

That matters because a bias-ply tire and a radial equivalent are different construction choices even when they are intended to fill a similar size role. Owners who want to preserve traditional appearance and construction usually stay with 640-13 bias-ply, while those considering a radial should verify wheel width and clearances first.

Radial equivalents for 640-13 include 175R13 as an 80-series metric radial, P175/75R13 as a 75-series P-metric radial, P185/70R13 as a 70-series P-metric radial, and 650R13 as a bias-look radial. Each option reflects a different way of translating the original bias-ply size into a radial format.

Those choices are useful because they give different profile and appearance directions while staying within the same general fitment conversation. The recommended rim-width range associated with these equivalents is 4 to 6 inches, but overall dimensions, wheel condition, and fender or steering clearance still need to be checked on the car itself.

Start by confirming the car's present primary size, either 640-13 or 700-13, and then match it to the appropriate radial-equivalent group. For 640-13, the options include 175R13, P175/75R13, P185/70R13, and 650R13, while 700-13 corresponds to 185R13, P185/75R13, and P205/70R13.

After that, inspect wheel width, wheel condition, and available clearance at the fenders and steering components. A radial equivalent is an alternative size path, not an automatic swap, so the car's actual wheel setup, suspension condition, and intended road use should all be reviewed before changing construction.

Begin with the correct primary size for the car, because the 1960 Mercedes-Benz 180 uses either 640-13 or 700-13, not a single universal fitment. Both are 13-inch bias-ply sizes, but they differ in nominal section width and in the product specifications available within each size.

Once the size is confirmed, compare construction, rim-width compatibility, load figure at the stated pressure, and the appearance you want the car to have. A buyer deciding between the two size families should focus first on matching the existing wheel-and-tire setup rather than choosing by brand or whitewall style alone.

The available products for the 1960 Mercedes-Benz 180 use a wide whitewall sidewall style. That applies to both of the covered bias-ply sizes, so the car's current choices stay rooted in a traditional whitewall presentation rather than a blackwall or redline alternative.

A wide whitewall can strongly influence the car's finished look, especially on a restoration-oriented sedan from this era. Even with the same general sidewall treatment, the final decision should still come back to the correct primary size, since 640-13 and 700-13 are different fitments and not interchangeable by appearance alone.

BFGoodrich and Firestone both offer tires for the 1960 Mercedes-Benz 180 within the available primary fitments. BFGoodrich is represented in 640-13 through the Silvertown Classic Bias Ply line, while Firestone is represented in 700-13 through the Firestone Classic Bias Ply line.

That means brand choice is tied directly to the size your car uses rather than being a simple side-by-side comparison within one fitment. The better approach is to confirm whether the car takes 640-13 or 700-13 first, then compare the product details that matter within that correct size family.

A period-style 1960 Mercedes-Benz 180 usually starts with the correct primary bias-ply size for the car, either 640-13 or 700-13. Staying with the original-style bias-ply construction preserves the vintage sizing format and the more traditional visual character associated with this sedan's era.

The next decision is how closely the finished car should reflect a restoration-oriented presentation versus a driver-oriented setup. Wide whitewall bias-ply options support the period look, while a radial equivalent may be worth considering if the goal includes more modern construction, provided the wheel and clearance checks are handled carefully.

Correct tire fitment matters because tire size, construction, and sidewall style all affect how a restored 1960 Mercedes-Benz 180 looks and sits. Using the proper 13-inch bias-ply size family helps keep the car visually aligned with its period rather than introducing a noticeably modern tire treatment.

For many restorations, that means confirming whether the car belongs on 640-13 or 700-13 before focusing on brand or whitewall choice. When exact originality is the goal, it is smart to compare the tire decision against marque-specific historical references, since period-style and exact factory delivery are not always the same thing.

Yes, modifications can affect tire fitment on a 1960 Mercedes-Benz 180. Even though the primary sizes here are 640-13 and 700-13 on 13-inch rims, aftermarket wheels, suspension changes, altered ride height, or brake and hub changes can all influence what fits safely and cleanly.

That is especially important when a car has been changed over time and no longer matches its earlier wheel setup. A good check includes wheel diameter, wheel width, tire clearance at full steering lock, and any signs that the body or suspension geometry has been altered from its more traditional configuration.

Before driving a 1960 Mercedes-Benz 180 on new tires, inspect the wheels for damage, confirm the tire size matches the intended setup, and make sure each tire is mounted correctly for the wheel in use. It also helps to verify inflation, valve condition, and clearances around the suspension and fenders.

A short, careful road test is a sensible next step after installation. Pay attention to rubbing, unusual vibration, steering pull, or signs that the tires are not centered properly on the car, especially if the Mercedes-Benz has older wheels, long-stored components, or a wheel-and-tire setup that has been changed in the past.

Collector-car tires on a 1960 Mercedes-Benz 180 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is minimal, older low-use tires can develop cracking, flat spotting, air loss, bulges, or other age-related issues that are easy to miss.

Routine inspection is especially important on a car that spends long periods parked. Keeping the Mercedes-Benz in a dry space away from prolonged sunlight and ozone sources, and checking the tires before each drive, helps catch condition problems early and protects both the tire investment and the car's roadworthiness.
