Willys 75 Sedan Delivery Tires

The 1953 Willys 75 Sedan Delivery uses two listed tire sizes: 6.50-15 and 670-15. Both are 15-inch bias-ply fitments. The 670-15 size has the broadest product support, with most offerings built for 15-inch rims in the 4.50 to 5.00 inch width range, while one heavier-duty 670-15 option is also listed for the same model year.

That means the correct choice depends on more than the badge on the body. Check the size stamped on the tire you are replacing, measure the wheel, and compare against factory literature or a Willys specialist if the vehicle has been restored, modified, or put back into service with different wheels over the years.

A 670-15 tire for the Willys 75 Sedan Delivery uses the older numeric bias-ply sizing system. The 670 portion refers to a nominal section width of roughly 6.70 inches, and the 15 is the rim diameter in inches. On the available Willys-fit products, that size is built as a bias-ply tire and appears in several period-style series and sidewall treatments.

The practical takeaway is that 670-15 is not interchangeable with every other 15-inch tire just because the rim diameter matches. Width, profile, and intended service all matter, so match the size exactly before moving on to cosmetic details such as blackwall, narrow whitewall, or wide whitewall styling.

The 1953 Willys 75 Sedan Delivery appears with both 6.50-15 and 670-15, even though both fit 15-inch wheels. That kind of split usually reflects differences in configuration, replacement practice, or intended use within the same model year rather than a simple year-to-year change. One size may suit a more standard passenger-car style setup, while the other aligns more closely with heavier-duty commercial service.

Because both sizes belong to the same year, the year alone is not enough to choose correctly. Look at the tire size already on the vehicle, inspect the wheel width, and consider whether the vehicle is being restored as a delivery sedan, displayed for judging, or driven with a more work-oriented bias-ply setup.

The listed Willys 75 Sedan Delivery tires are all bias-ply designs in older numeric sizing, and that type of collector tire should be treated as requiring a tube. Nothing in the listed fitments suggests a modern tubeless radial conversion. Tube use is part of the normal installation practice for preserving proper fit and operation on period-style wheels.

That matters during mounting, because the tube, flap choice where applicable, and wheel condition all affect how well the finished assembly performs. Have the wheels checked for corrosion, damage, and correct dimensions before mounting new tires, especially if the sedan delivery has been sitting for long periods or carries original steel wheels.

Start with the three basics on your 1953 Willys 75 Sedan Delivery: the size marked on the old tire, the actual rim diameter, and the wheel width. The listed choices are 6.50-15 and 670-15, both for 15-inch rims, but the 670-15 products commonly call for rims around 4.50 to 5.00 inches wide, with some variation by series. That makes the wheel itself an important part of the decision.

After that, compare the vehicle against period service literature, restoration records, or marque-club knowledge if there is any doubt. Utility vehicles are often altered during their working lives, so a Willys that looks original may still be running replacement wheels or later-service tires that do not reflect the intended fitment.

Willys 75 Sedan Delivery tires in 670-15 are available in blackwall, narrow whitewall, and wide whitewall styles. Blackwalls appear across several brands and suit the commercial, work-oriented character of a sedan delivery very naturally. Narrow and wide whitewalls are also offered in multiple period-style bias-ply lines for owners aiming at a more polished restored appearance.

Choosing between them depends on how the vehicle is being presented. A business-use restoration or more utilitarian interpretation usually leans blackwall, while a show-oriented or dealer-display style restoration may justify a whitewall treatment if it matches the era and presentation of the individual Willys 75 Sedan Delivery.

The Willys 75 Sedan Delivery tire offerings include Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA within the listed 670-15 fitment. Those brands span several period-style bias-ply families, including classic passenger patterns and a heavier-duty truck-oriented option. Brand choice therefore affects both appearance and intended character, not just the name on the sidewall.

For a restoration, many owners choose first by the visual look they want, then by the series that best matches the Willys' role. A blackwall commercial-style presentation, a narrow whitewall driver, and a broader whitewall show vehicle can all point to different brands even when the nominal tire size stays the same.

The Willys 75 Sedan Delivery listings include several distinct series in 670-15, such as Firestone Classic Bias Ply, US Royal Classic Bias Ply, Coker Classic Bias Ply, Universal Classic Bias Ply, Silvertown Classic Bias Ply, Excelsior Bias Ply, Turbospeed Mk4, Super Cushion, Custom Super Cushion, Super Cushion Deluxe, and Super Transport. Most are period-style passenger-car bias-ply lines, while Super Transport points toward a more truck-oriented duty role. The result is a mix of visual and service-character choices within the same nominal size.

That variety gives restorers room to match the tire to the build. A sedan delivery restored as a passenger-derived commercial vehicle may call for one of the classic bias-ply passenger series, while a harder-working interpretation may be better served by the heavier-duty series if its appearance and load character fit the vehicle.

A Willys 75 Sedan Delivery should be stored in a cool, dark, dry space with the tires kept away from direct sunlight, ozone sources, and chemical exposure. Clean the tires before storage, maintain proper inflation, and avoid leaving the full vehicle weight in one position for extended periods if the sedan delivery will sit for months at a time.

For longer storage, move the vehicle occasionally or support it in a way that reduces flat-spotting stress on the tires and suspension. Collector bias-ply tires reward careful storage habits, especially on utility vehicles that may carry more rear weight or have been parked for long intervals between shows and maintenance cycles.

Tires on a Willys 75 Sedan Delivery should be inspected before every drive and more thoroughly at regular service intervals, even if the vehicle covers very few miles. Look for sidewall cracking, uneven wear, tread separation signs, valve stem aging, and any tube-related issues such as gradual pressure loss. Bias-ply collector tires often age out long before they wear out.

That routine matters even more on a commercial-bodied classic because long storage, heavier cargo assumptions, and older wheel hardware can hide problems until the vehicle is moving. Include the spare in the inspection plan, and have any vibration, pull, or unusual ride behavior checked before the next outing.

Tires on a Willys 75 Sedan Delivery should be replaced when age, cracking, hardening, impact damage, irregular wear, or structural concerns appear, even if the tread still looks deep. Collector vehicles frequently accumulate time rather than mileage, so tread depth alone is not a reliable measure of serviceability. Any tire that has sat flat, run underinflated, or shows casing distress deserves immediate attention.

Owners should think in terms of condition, storage history, and inspection results rather than waiting for visible baldness. If the Willys has old tires of uncertain age, especially after long storage or decades-old restoration work, a professional collector-tire inspection is the right next step before returning the vehicle to road use.

The Willys 75 Sedan Delivery is associated here with two 1953 sizes: 6.50-15 and 670-15, both in period-style bias-ply form. The available replacement products for 670-15 span multiple classic series rather than pointing to a single universal original-equipment tire. That means the correct restoration answer depends on how the specific vehicle was equipped and presented when new.

For serious restoration work, use factory literature, period photography, and Willys club knowledge to narrow the exact configuration. Once the size is confirmed, you can choose a replacement tire whose sidewall style and series character match the vehicle's intended finish, whether commercial, showroom-stock, or period accessorized.

Correct tire fitment can absolutely affect both judging and overall presentation of a Willys 75 Sedan Delivery. Judges and knowledgeable enthusiasts notice whether the tire size, sidewall treatment, and general stance suit the vehicle's year and purpose. On a niche commercial-bodied Willys, the wrong tire can change the proportions and visual honesty of the restoration very quickly.

That does not mean every restored Willys must wear the same sidewall style, but it should wear a size and appearance consistent with the car's intended story. If the vehicle is being prepared for marque judging, verify the tire choice with Willys experts before final mounting rather than relying only on broad period trends.

The Willys 75 Sedan Delivery can be restored with blackwall, narrow whitewall, or wide whitewall tires within the listed 670-15 offerings. Blackwall is the most naturally commercial-looking choice for a sedan delivery, while narrow and wide whitewalls create a more dressy period presentation. The right answer depends on whether the vehicle is being restored as a working delivery body, a dealer-display type vehicle, or a personalized period classic.

A good restoration choice starts with the vehicle's trim level, paint treatment, and intended historical character. If the Willys is meant to reflect a practical business vehicle, blackwall usually keeps the look honest; if it is being restored as a polished showpiece, a tasteful whitewall may better suit the finished result.

A properly selected and correctly installed bias-ply tire can be suitable for public-road use on a Willys 75 Sedan Delivery when the entire vehicle is mechanically sound and the tire matches the wheel and intended use. The listed 670-15 products include passenger-style bias-ply options as well as a heavier-duty truck-oriented alternative. Safety depends on the complete package: tire age, wheel condition, tube installation, suspension health, brakes, and steering all matter.

That means a fresh set of correct tires should be viewed as one part of recommissioning, not the whole job. Before regular road use, have the Willys checked for alignment, wheel integrity, braking performance, and proper inflation so the tire can perform as intended on a 1950s utility vehicle.

Before driving a Willys 75 Sedan Delivery, check tire pressure, visible sidewall condition, tread condition, wheel fasteners, and any signs of tube leakage or bead-seat problems. Also inspect the spare, because an old spare on a collector vehicle is often far older than the four tires in use. Since the Willys uses older-style bias-ply fitments, any pull, shake, or repeated pressure loss deserves immediate investigation.

The wider pre-drive check should also include steering play, brake response, and wheel bearing condition. A sedan delivery may spend long stretches parked and then return to service, so even a short local trip is reason enough to make a full walk-around and mechanical check part of the routine.

A Willys 75 Sedan Delivery fitted with period-style bias-ply tires should be driven at moderate speeds that respect the vehicle's age, chassis design, and tire construction. Even when the tires are new, the steering, braking, suspension geometry, and road manners remain those of an early-1950s utility vehicle rather than a modern car. Safe speed is therefore determined by overall condition, tire type, and road environment, not by what modern traffic may encourage.

Owners should build speed gradually after installation and pay attention to tracking, heat, and ride behavior. If the Willys feels unsettled, wanders, or reacts poorly to road grooves, slow down and correct the underlying setup before attempting sustained highway use.
