1955 Willys Bermuda Tires

The 1955 Willys Bermuda uses a 640-15 tire size. That is a numeric bias-ply fitment mounted on a 15-inch rim, and it is the primary size used across the covered Base & Custom 6 Cyl. versions.

Once the size is confirmed, the next decision is usually appearance and construction rather than fitment range. In 640-15, the Bermuda owner can compare blackwall, narrow whitewall, and wide whitewall options, or look at radial equivalents separately while confirming wheel width and clearance before changing from the original bias-ply format.

The 1955 Willys Bermuda uses a 15-inch rim with its primary 640-15 tire size. That rim diameter is the critical starting point, because the tire size and the wheel must match at the bead seat before any further fitment questions are addressed.

Rim diameter alone does not settle the whole decision, especially on a collector vehicle that may have had wheel changes over the years. It is still worth confirming the actual wheel width on the car, particularly if a radial equivalent is being considered, since radial alternatives for 640-15 reference a 5-6 inch rim-width range.

Yes. The covered 1955 Willys Bermuda Base & Custom 6 Cyl. sub-models use the same 640-15 bias-ply tire size. That keeps the fitment side of the purchase relatively simple compared with vehicles that split tire sizes by trim or wheel package.

Even with shared sizing, it still pays to look closely at the actual wheels on the vehicle before ordering replacement tires. Many restored wagons have changed hands several times, and aftermarket wheels, old replacements, or mixed tire constructions can alter what is on the car now compared with the size that belongs on the Bermuda.

For the 1955 Willys Bermuda, 640-15 is a bias-ply tire size. That means the original sizing convention for this vehicle is rooted in vintage bias-ply construction rather than a modern radial size format.

Keeping the Bermuda in a 640-15 bias-ply format usually makes sense when the goal is a traditional mid-1950s look and feel. A radial alternative can still be considered, but it should be treated as a conversion decision rather than a simple same-construction replacement, with attention paid to wheel width, dimensions, and overall clearance.

Radial equivalents for 640-15 include 175R15 as the 80-series metric radial option, P175/75R15 as the P-metric 75-series option, and P185/70R15 as the P-metric 70-series option. Each one keeps the 15-inch rim diameter while moving into a modern radial sizing system.

Those equivalents are useful comparison points, but they are not automatic replacements for every Bermuda. The recommended rim-width range for the radial equivalents is 5-6 inches, so the actual wheel width on the car matters, along with checking fender and steering clearance before changing from the original 640-15 bias-ply fitment.

Start by confirming the wheel diameter and the actual rim width on the car, since the 640-15 radial equivalents reference a 5-6 inch rim-width range. It is also important to compare the chosen radial size against available space at the fenders, suspension, and steering range rather than assuming every equivalent behaves the same.

Construction changes can also affect how the Bermuda looks and feels on the road, so the intended use matters. A wagon kept for shows may favor the original bias-ply presentation, while a more regularly driven vehicle may justify a radial alternative after wheel compatibility, tire dimensions, and overall setup have been verified.

The first step is staying with the correct 640-15 size and confirming that the tire suits the wheel actually on the car. From there, the main differences are construction format, brand, sidewall style, tire series, and practical specs such as rim-width guidance, weight, and load capacity where those figures are available.

A Bermuda used for restoration-focused display may point toward a traditional bias-ply with the right visual treatment, while a road-driven wagon may lead you to compare radial equivalents separately. Matching the tire to the vehicle’s purpose usually produces a better result than choosing only by brand name or whitewall width.

The 1955 Willys Bermuda has 640-15 tire options in blackwall, narrow whitewall, and wide whitewall styles. That gives the owner a meaningful appearance choice within the correct primary size rather than forcing a compromise on fitment just to get a certain look.

Sidewall treatment can change the entire visual tone of a mid-1950s wagon. A blackwall keeps the presentation plainer and more utilitarian, while whitewall options add a stronger period-style accent, so it helps to choose the style that matches the vehicle’s trim level, restoration direction, and how original-looking the finished Bermuda needs to feel.

Tires for the 1955 Willys Bermuda in the 640-15 size are available from BFGoodrich, Firestone, Avon, and Excelsior. The assortment includes several vintage-style bias-ply series, giving the owner multiple ways to stay within the correct size while choosing a particular look and specification set.

Brand should be considered alongside sidewall style, tire series, wheel compatibility, and the intended use of the vehicle. Some Bermuda owners will focus on a whitewall presentation, while others may prefer a blackwall tire with a more understated appearance, so comparing the complete combination makes more sense than choosing by brand alone.

A period-style 1955 Willys Bermuda generally starts with the correct 640-15 bias-ply size. From there, the choice usually comes down to whether the wagon looks right with a blackwall, a narrow whitewall, or a wider whitewall, along with the tire series and brand presentation that best match the vehicle’s restoration direction.

Bias-ply construction preserves the original sizing format and visual character more closely than a modern radial conversion. If exact originality matters beyond general period style, it is wise to compare the tire choice against marque-specific photos, build-era references, and restoration documentation rather than assuming any whitewall treatment is automatically correct for every Bermuda.

Tire construction changes more than road feel on a restored 1955 Willys Bermuda; it also changes the vehicle’s visual attitude. A 640-15 bias-ply keeps the traditional vintage sizing format, while a modern radial equivalent introduces a later-style construction even though it still uses a 15-inch rim.

For many restorations, that distinction matters because the tire sidewall shape and overall presentation contribute heavily to the finished look. Owners chasing a more authentic mid-1950s impression often stay with bias-ply, while owners prioritizing road use may accept the visual change of a radial after confirming that the alternative size suits the wheel and body clearances.

Yes. Modifications can absolutely affect tire fitment on a 1955 Willys Bermuda, even when the intended replacement stays close to the original 640-15 sizing. Aftermarket wheels, changed wheel width, altered offset, suspension work, lowering, or body repairs can all change the space a tire has at the fender and during steering movement.

That is why an owner should inspect the actual setup on the car instead of relying only on the model year and nameplate. A Bermuda that still has stock-style wheels presents a different decision from one with later wheels or chassis changes, especially if a radial equivalent is being considered instead of the original bias-ply format.

Before road use, inspect wheel condition, valve stems, and overall clearance at the fenders, suspension, and steering range. The tire itself should be checked for proper inflation, secure seating on the wheel, and any visible issues such as cuts, bulges, or uneven contact that could point to a wheel or chassis problem.

A collector wagon also deserves a broader look at brake condition, steering response, and suspension wear before it sees regular miles. Tires do their job best when the rest of the chassis is in sound shape, so confirming alignment-related wear patterns and watching for rubbing or air loss during the first drives is a sensible final step.

Maintain 640-15 tires on a collector 1955 Willys Bermuda with regular pressure checks, visual inspections, and careful storage habits. Even low-mileage collector tires should be watched for cracking, weathering, flat spotting, cuts, bulges, and slow air loss, because age and storage conditions can matter as much as accumulated road miles.

A Bermuda that sits for long periods benefits from a clean, dry storage area away from prolonged sunlight, heat, and ozone sources. Periodic movement helps reduce long-term flat spotting, and any tire that shows aging or condition concerns should be evaluated before road use, even if the tread still looks serviceable.
