Ford Zephyr Tires

Ford Zephyr was one of Ford of Britain’s defining postwar saloons, and the 1953 to 1956 Ford Zephyr belongs to the years when British family and executive cars were moving from prewar tire conventions toward more modern sizing and road manners. That transition matters here because Ford Zephyr appears with two different size formats across the same production span, one in older numeric bias-ply form and one in later radial-style metric form. Choosing correctly is not just a matter of model year. Anyone fitting tires to a Ford Zephyr should first confirm whether the car is being kept on period-style bias-ply rubber or has been set up around the alternate 13-inch radial-size equivalent.

Ford Zephyr Tire Size Guide

Ford Zephyr uses 2 distinct tire sizes across the 1953 to 1956 production span. Those sizes share a 13-inch rim diameter, but they represent two different sizing conventions: an older numeric bias-ply size and a later radial-style metric equivalent.

175R131953-1956Euro-metric radial

175R13 is the radial-size option listed for Ford Zephyr models from 1953 through 1956. The 175 indicates nominal section width in millimeters, the R identifies radial construction, and the 13 is the rim diameter in inches. Choose this size when the car is set up for a radial-size fitment and confirm overall clearance and wheel suitability before selecting.

640-131953-1956Numeric bias-ply

640-13 is the period-style numeric bias-ply size listed for Ford Zephyr models from 1953 through 1956. The 640 indicates the nominal section width in the older inch-based system with the decimal omitted, and the tire fits a 13-inch rim. Choose this size when maintaining the original bias-ply character of the car; a tube is required, and one product in this size is listed as new-old-stock original period production — contact the supplier for age and condition details before ordering.

Ford Zephyr Tires by Year

The year listing shows which Ford Zephyr tire sizes apply from 1953 through 1956 and helps narrow the choices to the specific car you are working on. Every year in this range carries both listed sizes, so the deciding factor is whether the car is using the period-style numeric bias-ply fitment or the alternate radial-size equivalent.

Frequently Asked Questions

The FAQ below focuses on the two size conventions used on Ford Zephyr from 1953 to 1956, how to distinguish bias-ply from radial sizing, and what to consider when a listed tire is a new-old-stock period item.

Size Basics & Fitment

Ford Zephyr models from 1953 through 1956 use two listed tire sizes: 175R13 and 640-13. The 175R13 is a radial-size format for a 13-inch wheel, while the 640-13 is an older numeric bias-ply size that also fits a 13-inch wheel. The currently listed 640-13 product is built for a 13-inch rim with a 4.00 to 4.50 inch rim-width range.

The practical choice depends on how the individual Ford Zephyr is equipped and what driving character or restoration style you want to preserve. A car kept in period-correct bias-ply form usually points toward 640-13, while a car using the radial-size equivalent may suit 175R13. Check the tires already on the car, measure the wheel, and compare with factory literature or marque references before deciding.

On Ford Zephyr, 640-13 is a numeric bias-ply size rather than a modern metric radial size. The 640 represents the nominal section width in the older inch-based system with the decimal omitted, and the 13 identifies the wheel diameter in inches. It is a period-type size commonly associated with mid-century bias-ply fitments.

That matters because a 640-13 should be matched to the correct style of wheel and to a restoration plan that suits bias-ply construction. The listed product for this size uses a 13-inch rim and a 4.00 to 4.50 inch wheel width range, which gives you a concrete check against the car in your garage. If the goal is factory-era appearance and handling feel, this is the size format most buyers investigate first.

A 1953 Ford Zephyr has both 175R13 and 640-13 listed because the model appears with two different sizing conventions for the same production years. One is an older numeric bias-ply format and the other is a radial-size metric equivalent. Both are tied to 13-inch wheels, so the difference is not wheel diameter but tire type and sizing system.

That split means year alone does not settle the decision on a Ford Zephyr. You need to identify whether the car is being restored to period bias-ply specification or whether it has been set up around the alternate radial-size fitment. Looking at the existing wheel and tire combination, the owner’s literature, and the intended use of the car will usually point you in the right direction.

Ford Zephyr tires in the listed 640-13 bias-ply size require tubes. That requirement follows the construction and style of the available bias-ply product in this size and is typical of many period tire applications. The 175R13 listing is a radial-size format, so tube use depends on the specific tire and wheel combination rather than on the size code alone.

If your Ford Zephyr is running the 640-13 period-style bias-ply fitment, plan the tire, tube, and wheel as one system rather than treating the tube as an afterthought. Tube condition, flap requirements where applicable, and the inner surface of the wheel all affect reliability. A Zephyr fitted with the radial-size option should be checked carefully for wheel compatibility before assuming tubeless or tube-type use.

Buying the Right Tire

A 1955 Ford Zephyr can use either 175R13 or 640-13, so the correct choice comes from the actual setup of the car rather than from the year alone. Both sizes are listed across the full 1953 to 1956 span, and both correspond to 13-inch wheels. The key distinction is whether the car is using period-style numeric bias-ply sizing or the alternate radial-size fitment.

Start by reading the sidewall on the existing tires, then verify wheel diameter and wheel width before replacing anything. If the car is a restoration, compare those findings against period literature and club knowledge to decide whether preserving authenticity or selecting a different driving feel matters more. That process is especially important on a Ford Zephyr because the two listed sizes represent different tire conventions, not just interchangeable labels.

The listed Ford Zephyr product in 640-13 is offered with a wide whitewall sidewall style. That gives restorers and period-minded owners a distinctly mid-century appearance that suits many postwar sedans and saloons. No additional sidewall style is listed here for the available Zephyr product.

Sidewall style affects the look of a Ford Zephyr almost as much as wheel finish or hubcaps, so it should match the visual direction of the car. A wide whitewall tends to emphasize a formal restoration or a U.S.-market period aesthetic, while some owners may prefer to verify whether their particular Zephyr originally carried a plainer presentation. Check period photos of the specific car style before making the final call.

Made-to-order is a product characteristic used on some collector tire listings to indicate that the tire is produced to fulfill demand rather than treated like a routine shelf item. For Ford Zephyr, that matters most when comparing available products across older specialty sizes. It is simply a note about how the tire is supplied, not about whether the size itself is correct for the car.

From a buyer’s standpoint, the more important issue is still fitment accuracy on the Ford Zephyr. Confirm the size code, wheel diameter, and whether you are staying with bias-ply character or using the alternate radial-size equivalent before focusing on how a tire is supplied. Specialty collector tires are often chosen for authenticity and proper proportions, so getting the specification right remains the first priority.

One listed Ford Zephyr tire in 640-13 is identified as new-old-stock original period production. New-old-stock, or NOS, means an older tire that was manufactured in the period and remained unused rather than a newly made reproduction. That gives it authenticity appeal, but age matters even when tread depth and appearance still look excellent.

An NOS tire for a Ford Zephyr should be treated as a specialist item, with condition, storage history, and intended use all considered before road service. Many collectors reserve period tires for display, concours, or limited demonstration use rather than regular driving. If the car will be driven with any frequency, a newly manufactured tire in the correct size is usually the more practical path.

Maintenance & Longevity

A stored Ford Zephyr should be kept in a cool, dry, dark space with the tires protected from direct sunlight, ozone sources, and petroleum contamination. Clean concrete is acceptable, but long-term storage is improved if the tires are isolated from moisture and the car is kept away from electric motors or welders that generate ozone. Tire pressure should be maintained so the sidewalls are not carrying unnecessary deformation.

If the Ford Zephyr will sit for months at a time, move it periodically or place it on cradles so one section of the tread is not loaded continuously. Bias-ply tires are especially prone to flat spotting after storage, and any older collector tire benefits from reducing sustained weight on one contact patch. Storage habits have a direct effect on ride quality, casing life, and sidewall appearance.

Tires on a Ford Zephyr should be inspected before each meaningful drive and more thoroughly at regular intervals through the season. Look for sidewall cracking, tread separation, air loss, irregular wear, bead issues, and signs that the wheel itself may be damaging the tire or tube. On a collector car, long periods of inactivity make visual inspection just as important as mileage.

A Ford Zephyr running bias-ply tires deserves especially careful checks because age and storage can affect serviceability long before the tread looks worn out. Include valve stems, tube condition where applicable, and the inside of the wheel in the inspection routine. Catching a problem in the garage is far better than discovering it after the car is already at road speed.

Ford Zephyr tires should be replaced when age, cracking, casing stiffness, vibration, repeated air loss, or visible structural deterioration appears, even if the tread still looks usable. Collector tires often age out before they wear out. That is particularly true of older bias-ply constructions and absolutely true of any period new-old-stock tire whose calendar age is already substantial.

Waiting for tread wear alone is the wrong standard on a Ford Zephyr that sees occasional use. A tire can retain deep tread and still be unsuitable because the rubber and internal structure have hardened or degraded over time. If there is any doubt about an older tire, especially an NOS example, specialist inspection is wise before the car returns to regular road use.

Restoration & Authenticity

Ford Zephyr is listed with both 640-13 and 175R13 across the 1953 to 1956 model span, so there is more than one period-relevant size convention associated with the model. The available product tied to the period-style fitment is a BFGoodrich Silvertown Classic Bias Ply in 640-13 with a wide whitewall. That points restorers toward the older bias-ply presentation when authenticity is the main goal.

Original fitment on an individual Ford Zephyr should still be matched against period manuals, factory literature, and marque-club references, especially if the car has been altered over the years. A restored car aimed at strict authenticity often follows the bias-ply route, while a driver-oriented car may be compared against the radial-size equivalent. The important part is choosing deliberately rather than assuming one size suits every surviving Zephyr.

Correct tire fitment can affect both presentation and judging on a Ford Zephyr because tire size, construction, and sidewall style strongly influence stance and period character. Judges and experienced collectors often notice whether a car sits on a period-appropriate bias-ply size or on a later-looking alternative. On many restorations, tires are one of the first visual cues that signal authenticity or compromise.

That does not mean every Ford Zephyr must be restored the same way, but it does mean the tire choice should match the car’s intended role. A concours or preservation car usually benefits from the most era-appropriate fitment, while a touring car may prioritize a different feel. Marque clubs and photos of well-restored examples are useful references when balancing value, judging standards, and real-world use.

The listed Ford Zephyr product in 640-13 is available with a wide whitewall, which gives the car a strong mid-1950s period presentation. Whitewall styling was widely associated with upscale postwar passenger cars, and it can look very natural on a Zephyr restored in a formal or export-market style. No other sidewall style is listed here for the available Zephyr product.

The right sidewall for a Ford Zephyr restoration depends on how strictly you are matching a specific car and market presentation. Period photos, dealer literature, and marque expertise can help determine whether a wide whitewall suits the exact car you are restoring. If appearance and judging matter, sidewall style should be chosen with the same care as paint color, trim, and wheel finish.

Safety & Road Use

A properly sized, properly mounted tire can be suitable for driving a Ford Zephyr on public roads, but safety depends on far more than the size code alone. Construction type, age, wheel condition, inflation, alignment, and the overall mechanical state of the car all matter. A newly manufactured collector tire and an older new-old-stock tire should never be judged by sidewall appearance alone.

A Ford Zephyr that is driven regularly should have every tire inspected as part of a broader roadworthiness check rather than treated as a cosmetic accessory. If the car is running older bias-ply tires, expect handling and braking feel to differ from modern cars and drive accordingly. Conservative speeds and careful pre-drive inspection are part of safe use on any mid-century collector car.

Before driving a Ford Zephyr, check tire pressure, sidewall condition, tread condition, wheel security, valve stems, and any sign of tube-related air loss if the car is on bias-ply 640-13 tires. Look for flat spotting after storage and inspect for cracking or bulges that can appear on older collector rubber. Make sure the spare is also usable and correctly sized.

The point of that routine is to catch age-related issues before they turn into a roadside problem. A Ford Zephyr often spends long periods parked, and inactivity can be just as hard on tires as mileage. Add a quick check of steering feel and brake response in the first few moments of driving, especially if the car has not been used recently.

A Ford Zephyr on period-style tires should be driven at moderate speeds that respect the age, construction, and overall condition of the tire as well as the chassis itself. Bias-ply tires do not deliver the same straight-line stability, braking feel, or heat tolerance most drivers expect from modern passenger tires. If the tire is an older period item, caution matters even more.

The sensible approach with a Ford Zephyr is to let tire condition and vehicle preparation set the pace rather than the engine’s capability. A well-sorted car on fresh collector tires can be enjoyed on ordinary roads, but it still deserves measured driving and extra following distance. If the car is fitted with any tire of uncertain age, restrict use until it has been professionally evaluated.
