Willys Universal Tires

Willys Universal models in this 1960 through 1963 group use one listed tire size: 670-15. All available products for that fitment use a 15-inch rim diameter, and the listed rim-width recommendations vary by tire, including examples in the 4.00 to 4.50-inch, 4.50 to 5.00-inch, and 5.00 to 6.00-inch ranges. Every product in this group is a bias-ply tire.

That makes size selection straightforward, but wheel details still matter. A Willys Universal that has been restored, modified, or put back into service over many years may no longer be wearing its original wheels, so measure the rim diameter and width on the vehicle before deciding which 670-15 tire is the best match.

On a Willys Universal, 670-15 is a numeric bias-ply tire size. The 670 refers to a nominal section width of roughly 6.70 inches, and the 15 identifies the wheel diameter in inches. In this Willys Universal range, the available 670-15 tires are all built as bias-ply products for 15-inch rims.

Modern buyers sometimes expect a more detailed metric code, but older American sizing was much simpler. The key practical step is to treat 670-15 as both a size and a construction-era clue: it points you toward period-style bias-ply fitment, so handling feel, appearance, and wheel compatibility should be considered together rather than separately.

Willys Universal tires in this range are all listed in a numeric bias-ply format and all available products are bias ply. A tube is required. That applies across the 670-15 options, regardless of whether you choose a blackwall, narrow whitewall, or wide whitewall version.

Tube fitment is an important part of a correct vintage tire installation, especially on a utility vehicle that may see irregular use and long storage periods. Make sure the tube and flap arrangement, if required by the wheel type, matches the wheel condition and the tire size so the complete assembly is set up properly.

A 1960 Willys Universal in this model group uses 670-15. The same size continues through 1961, 1962, and 1963, and the listed products all fit 15-inch rims. The main variables are not year-specific size changes but the wheel width, the tire series, and the sidewall style offered within the 670-15 range.

Start by reading the size on the tire already mounted, then verify the wheel's actual diameter and width. If the vehicle has replacement wheels or has been adapted for work or trail duty at some point in its life, those changes can matter more than the model year when deciding which 670-15 version is the right one.

Willys Universal tires in 670-15 are available in blackwall, narrow whitewall, and wide whitewall styles. The product range includes plain blackwall utility-style tires as well as narrow and wider whitewall variations from several brands. That gives owners room to choose between a more workmanlike appearance and a more dressed-up period look.

For many Willys Universal restorations, blackwall is the natural visual choice because it suits the model's practical character. Whitewalls can still be appropriate when the goal is a more personalized or era-flavored presentation, so it helps to match the sidewall style to the specific vehicle's history and the way you intend to present it.

The listed Willys Universal tire offerings include Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Goodyear, Avon, and STA. Those products appear across several bias-ply series, including Firestone Classic Bias Ply, US Royal Classic Bias Ply, Coker Classic Bias Ply, Silvertown Classic Bias Ply, Universal Classic Bias Ply, Super Cushion, Custom Super Cushion, Super Cushion Deluxe, Turbospeed Mk4, and Super Transport.

Brand choice should follow your goal for the vehicle. Some Willys Universal owners want a straightforward blackwall utility look, some want a period passenger-car presentation with whitewalls, and others need a heavier-duty visual or functional approach, so compare brand, series, sidewall treatment, and wheel-width compatibility together.

Willys Universal tires in 670-15 are offered in several series, including Firestone Classic Bias Ply, US Royal Classic Bias Ply, Coker Classic Bias Ply, Universal Classic Bias Ply, Silvertown Classic Bias Ply, Excelsior Bias Ply, Goodyear Super Cushion, Goodyear Custom Super Cushion, Goodyear Super Cushion Deluxe, Avon Turbospeed Mk4, and STA Super Transport. All are bias-ply constructions, but they represent different period-style designs, branding families, and visual treatments within the same size.

That means the decision is less about basic fit and more about matching the tire to the character of your Willys Universal. A passenger-car style bias ply, a period performance-flavored bias design, and a truck-oriented Super Transport can all fit the same nominal size while giving the vehicle a noticeably different stance and personality.

A Willys Universal should be stored in a cool, dry, dark space with clean tires and proper inflation for the tire and wheel combination. Keep the vehicle away from direct sunlight, ozone sources such as electric motors and welders, and long-term exposure to moisture or petroleum contamination. Bias-ply collector tires benefit from stable conditions and minimal environmental stress.

If the Willys Universal will sit for extended periods, move it occasionally so the tires are not loaded in one position for months at a time. Owners who store a vehicle seasonally often reduce stress further by using stands appropriately or by rolling the vehicle periodically, while still keeping the tire assembly supported correctly.

Tires on a Willys Universal should be inspected before driving and given a more careful check several times خلال the year even if the vehicle sees very little mileage. Look for cracking, uneven wear, sidewall damage, tread separation signs, valve issues, and any change in how the vehicle sits or steers. Bias-ply tires on older utility vehicles deserve regular attention because age and storage conditions matter as much as miles.

A hands-on inspection routine is especially useful on a Willys Universal that spends time parked between events or occasional road use. Check pressure when cold, inspect the spare as well as the road tires, and pay attention to any vibration or pull that appears after storage, since those clues often show up before obvious visual damage.

Tires on a Willys Universal should be replaced when age, cracking, impact damage, deformation, or internal deterioration make continued use questionable, even if tread depth still looks acceptable. Collector vehicles often age out tires before they wear them out. A bias-ply tire can appear serviceable at a glance while still needing replacement because of time, storage history, or casing condition.

That is why replacement decisions should be tied to inspection results rather than tread alone. If a Willys Universal has sat for long stretches, carries older tires of uncertain history, or shows any structural concern, a specialist tire inspection is the prudent next step before putting the vehicle back into regular road or trail service.

The Willys Universal listings for 1960 through 1963 center on 670-15 sizing, with available products offered in multiple bias-ply series and sidewall styles. The range includes blackwall, narrow whitewall, and wide whitewall choices, along with several brand families. That means the size itself is consistent here, while appearance and series selection vary within that fitment.

For a restoration aimed at factory-style accuracy, the most important step is confirming how your specific Willys Universal was equipped when new. Period photos, original sales literature, surviving examples, and marque specialists can help determine whether a simple blackwall utility presentation or a more styled passenger-car look is the best historical match.

Correct tire fitment can influence both the value and the judged authenticity of a Willys Universal. Judges and knowledgeable buyers notice whether the tire size, sidewall treatment, and overall stance suit the vehicle's year and intended character. Even when the listed size is straightforward, the visual difference between blackwall and whitewall choices can change how faithful the finished vehicle appears.

For a driver-quality Willys Universal, the goal may be a practical bias-ply that looks right and works with the existing wheels. For a show or points restoration, it is worth aligning size, sidewall style, and brand character with the standard used by the club, event, or restoration philosophy guiding the project.

Willys Universal tires are available here in blackwall, narrow whitewall, and wide whitewall forms. Blackwall is usually the most natural restoration direction for a utility-focused Willys Universal, while narrow and wide whitewalls create a more stylized period appearance. The correct choice depends on how the individual vehicle was delivered, used, and later restored.

If authenticity is the goal, compare your Willys Universal against original photos, trim level cues, and period literature before choosing a sidewall style. If the vehicle is being restored as a personalized 1960s-era truck or Jeep-based utility vehicle, a whitewall may suit the look, but a blackwall generally preserves the most straightforward work-vehicle character.

A properly installed, correctly sized 670-15 bias-ply tire can be suitable for public-road use on a Willys Universal when the entire vehicle is mechanically sound and the tires are in healthy condition. Safety depends on more than size alone: wheel condition, tube installation, alignment, brakes, steering components, and the tire's age all matter. Collector tires should always be judged as part of the complete vehicle system.

That means a roadworthy Willys Universal starts with inspection, not assumption. Before regular driving, evaluate the wheels, confirm pressures appropriate to the tire and load, and make sure the vehicle tracks and brakes correctly, because an older utility vehicle on bias-ply tires will communicate problems differently than a modern vehicle on radial rubber.

Before driving a Willys Universal, check cold tire pressure, visible sidewall condition, tread condition, valve stems, wheel security, and any signs of tube-related air loss. Also inspect the spare, because older utility vehicles often depend on it more than modern cars do. Since all listed tires here are bias ply, expect them to respond differently to underinflation, uneven loading, and long storage than modern radials would.

A short walkaround is not enough if the Willys Universal has been sitting. Drive only after confirming brakes, steering play, wheel-bearing feel, and overall mechanical readiness, then begin with a cautious low-speed test so any pull, vibration, or heat buildup in the tires can be noticed before the vehicle is used normally.

A Willys Universal on period-style bias-ply tires should be driven at sensible, moderate speeds that match the vehicle's age, design, condition, and road environment. Even when the tire size is correct, a vintage utility vehicle on bias plies will not feel or respond like a modern SUV or truck on radial tires. Stability, braking feel, and steering correction all require more driver attention.

The practical rule is to let the vehicle set the pace. Keep speeds conservative, especially on rough pavement, in crosswinds, or after long storage, and increase only when the Willys Universal has proven stable, properly inflated, and mechanically sorted in real driving conditions.
