1963 Willys Tire Fitment Guide

1963 Willys vehicles use two tire sizes: 670-15 and 710-15. The 670-15 fits both the 1963 Willys Universal and the 1963 Willys Wagoneer, while the 710-15 is used on the 1963 Willys Wagoneer only. Both sizes are bias-ply fitments for 15-inch rims. Rim width coverage runs from 4.50 to 6.00 inches for 670-15 products and 5.00 to 5.50 inches for 710-15 products, depending on the tire.

That means a 1963 Willys owner should identify the model first, then confirm which size is already on the vehicle or which wheel width is being used. The Universal has the simpler path because it stays with 670-15, while the Wagoneer needs closer checking because either 670-15 or 710-15 may be appropriate. Matching the size to the actual wheel before choosing a sidewall style helps avoid unnecessary backtracking.

On a 1963 Willys tire, 670-15 is a numeric bias-ply size. The 670 portion is the nominal section-width designation used in period sizing, and the 15 identifies the rim diameter in inches. In the 1963 Willys range, 670-15 is the shared size used by both the Universal and the Wagoneer. Available versions include blackwall and wide whitewall styles from Firestone, US Royal, Coker Classic, and Universal Vintage Tire.

A 1963 Willys owner looking at 670-15 is usually deciding more about appearance and wheel-width compatibility than about construction type, since every option here is bias-ply. It is a useful size for someone restoring a Universal or confirming a common Wagoneer fitment. Checking the tire’s approved rim width range is especially important because some 670-15 options are intended for narrower wheels than others.

No, not all 1963 Willys models use the same tire size. The 1963 Willys Universal uses 670-15, while the 1963 Willys Wagoneer uses 670-15 or 710-15. Both sizes are 15-inch bias-ply fitments, but they are not interchangeable by assumption simply because they share the same rim diameter. The Wagoneer’s broader size range is the reason model identification matters on this year-make page.

That difference becomes important when a buyer knows only the year and make and has not yet narrowed the vehicle down further. A Universal owner can focus directly on 670-15, but a Wagoneer owner should confirm what is already mounted, what wheel width is present, and whether the goal is to preserve an existing stance. Getting the model right first makes the size decision much easier.

1963 Willys tires are available in blackwall and wide whitewall styles. The 670-15 size appears in both blackwall and wide whitewall versions from several brands, and the 710-15 size also comes in both blackwall and wide whitewall form. For a utility-oriented Willys such as the Universal, blackwalls are often the more natural visual choice. On a more upscale or personalized Wagoneer, either blackwall or wide whitewall can make sense depending on the restoration direction.

Sidewall choice affects appearance more than fitment, so it is best treated as the final decision after size and wheel compatibility are confirmed. Owners building a factory-style workhorse usually lean toward blackwalls, while those emphasizing period presentation may prefer a whitewall treatment. If show judging is part of the plan, it is smart to compare your chosen sidewall style with period photos and marque-specific guidance.

1963 Willys vehicles are covered by Firestone, US Royal, Coker Classic, Universal Vintage Tire, and BFGoodrich. In 670-15, the available brands are Firestone, US Royal, Coker Classic, and Universal Vintage Tire. In 710-15, the available brands are BFGoodrich and Firestone. Every option across both sizes is a bias-ply tire, so the brand choice is mainly a matter of preferred styling, sidewall treatment, and the exact wheel-width range each tire supports.

A Universal owner will spend most of the time comparing 670-15 offerings, while a Wagoneer owner may need to compare both the size and the brand roster before deciding. Some buyers gravitate toward a traditional American brand identity, while others focus on the exact sidewall appearance that best suits the vehicle. Narrowing the correct size first keeps the brand comparison much more useful.

For the 1963 Willys in 670-15, Firestone and Coker Classic differ in sidewall treatment, wheel-width range, weight, and rated load figure. The Firestone 670-15 appears as a blackwall tire with a 4.50 to 5.00 inch rim width range, a 1450-pound load rating at 32 psi, and a 23-pound weight. The Coker Classic 670-15 appears as a 2.75-inch whitewall with a 5.00 to 6.00 inch rim width range, a 1550-pound load rating at 32 psi, and a 21-pound weight.

That makes the comparison less about brand reputation alone and more about what wheel and appearance goal the vehicle actually has. A buyer working with a narrower 15-inch wheel may naturally fall toward the Firestone fitment range, while a buyer using a wider wheel and wanting a whitewall look may be better served by the Coker Classic. The wheel itself should be measured before settling on either one.

1963 Willys tire rim-width requirements depend on the size and the specific product. In 670-15, approved rim widths run from 4.50 to 5.00 inches on some tires and 5.00 to 6.00 inches on others. In 710-15, the available tires use a 5.00 to 5.50 inch rim width range. Both sizes fit 15-inch rims, but width compatibility still needs to be checked carefully.

That is especially important for a 1963 Willys Wagoneer, since it appears with both 670-15 and 710-15 and may not always be wearing its original wheels after decades of service. Measuring the wheel before ordering is the simplest way to avoid sidewall shape issues or mounting problems. Owners comparing several tire brands within the same size should look at width range just as closely as appearance.

The available 1963 Willys tire information does not show tube-type or tubeless markings within the size descriptions, so the practical approach is to verify the sidewall marking on the exact tire and consider the wheel design it will be mounted on. Both 670-15 and 710-15 are bias-ply 15-inch sizes, and older wheel constructions often influence whether tubes are used as much as the tire itself.

A 1963 Willys owner should confirm tube use before mounting rather than assuming every bias-ply product is handled the same way. Original-style steel wheels, wheel condition, and how the tire is marked all matter. If the vehicle is being restored closely to period practice, or if the wheels have seen years of service, a marque specialist or experienced vintage tire installer is the right final checkpoint.

Because both 670-15 and 710-15 are 15-inch sizes, original 1963 Willys wheels of the correct diameter can often accept either size from a diameter standpoint. Width is the deciding factor after that. The 670-15 options span rim widths from 4.50 up to 6.00 inches depending on the product, while 710-15 options are built around a 5.00 to 5.50 inch range.

That means a 1963 Willys Wagoneer owner should not assume every original 15-inch wheel is equally suitable for both sizes without measuring it first. A Universal owner has a more straightforward path because only 670-15 applies. If the vehicle has replacement wheels or a long history of owner changes, checking actual wheel width becomes more important than relying on what should have been there originally.

A 1963 Willys should be stored away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber prematurely. Clean, dry floors are better than damp ground, and inflation pressure should be kept at a stable level during storage. Because 1963 Willys fitments here are bias-ply, they are more prone to temporary flat-spotting during long periods of sitting than a modern radial would be.

Moving the vehicle periodically helps change the tire’s contact patch and reduces the tendency to settle in one position. For longer storage, some owners use stands to reduce static load, but the chassis should still be supported correctly and safely. A short, gentle warm-up drive after storage often smooths out minor flat-spotting if the tires are otherwise in sound condition.

On a 1963 Willys, tire life is usually judged more by age and condition than by mileage, because many collector vehicles are driven infrequently. A good rule is to begin evaluating tires closely once they are around five to seven years old and to consider replacement as they approach ten years, even if tread depth still looks usable. The DOT date code on the tire is the best way to establish age.

That matters because a lightly used 1963 Willys can still be riding on rubber that looks acceptable at first glance but has hardened with time. Sidewall checking, vibration, and reduced flexibility often become more meaningful than tread wear alone. If the vehicle’s age is unknown or the date code reveals older rubber, replacement deserves serious consideration before any regular road use.

Tires on a 1963 Willys should be inspected before every drive and again before any longer outing. Look closely for sidewall cracking, weather checking, cuts, bulges, uneven tread wear, and slow pressure loss. Since these are older-style bias-ply fitments, visual checks are especially important after seasonal storage or long idle periods. The spare should be inspected on the same schedule rather than forgotten until roadside use is needed.

That routine is particularly important on a collector 4x4 or utility vehicle because age, storage conditions, and occasional use can all affect the tire more than mileage does. A quick walkaround catches problems while they are still small and manageable. If the vehicle uses tubes, valve stems and air retention deserve the same attention as the tread and sidewalls.

The 1963 Willys Universal uses 670-15 in this year-make range, and bias-ply construction is the era-correct type for a utility-focused American vehicle of this period. That matches what enthusiasts would expect on an early-1960s Willys product, especially one rooted in Jeep’s traditional design language. Original-equipment brand choice could vary by market, distributor, and service replacement history, so the most reliable confirmation path is still period literature and marque-club guidance.

For restoration purposes, the key pieces are the correct size, the correct bias-ply construction, and a sidewall style that suits the way the vehicle was originally presented. A blackwall usually aligns naturally with a working Universal, while some restorations may still choose a whitewall for a particular look or local-market flavor. Owners building toward judging standards should compare against factory photos and club references before making the final call.

Correct tire fitment matters a great deal when showing a 1963 Willys, especially in classes that emphasize authenticity. Judges and knowledgeable enthusiasts often notice tire size, construction type, sidewall treatment, and overall stance before they ever look at finer details. On a vehicle from 1963, an obviously modern construction or an incorrect sidewall style can stand out quickly, even if the tire physically fits the wheel.

That does not mean every event applies the same standard, but it does mean tire choice affects the vehicle’s visual credibility. A Universal built as a utility restoration may call for a different look than a Wagoneer restored with more upscale presentation in mind. Marque clubs and show-rule books are the best sources for event-specific expectations if points judging is part of the goal.

For the 1963 Willys in 710-15, BFGoodrich and Firestone share the same basic fitment envelope but differ in styling choices and weight. Both brands carry a 1550-pound load capacity at 32 psi and fit 15-inch rims in the 5.00 to 5.50 inch width range. Firestone appears as a blackwall at 24 pounds, while BFGoodrich appears in both blackwall and wide whitewall versions at roughly 21 to 23 pounds depending on sidewall treatment.

A restorer comparing these two 710-15 options is usually choosing the visual personality of the vehicle as much as the tire itself. Firestone offers a straightforward blackwall look, while BFGoodrich gives the Wagoneer owner the choice of either blackwall restraint or a more pronounced whitewall presentation. Since the fitment specs align closely, appearance and wheel-correct styling become the main deciding points.

1963 Willys tires can be suitable for highway driving when they are in sound condition, correctly sized, properly inflated, and used within the limits of their design. The available 670-15 and 710-15 choices here are bias-ply tires, and no speed-rating markings appear in the size descriptions. On a vehicle of this age, tire condition is only one part of the highway equation, because steering, brakes, suspension, and the vehicle’s overall state matter just as much.

A driver should think of highway use in terms of the entire 1963 Willys package rather than the tire alone. Bias-ply construction delivers an authentic period feel, but it does not behave like a modern passenger radial in tracking and response. A careful pre-drive inspection, realistic cruising expectations, and confidence in the vehicle’s mechanical condition are the keys before planning sustained road miles.

Pressure on a 1963 Willys should be matched to the exact tire size and product, then checked against the vehicle’s original recommendations. In the available range here, 670-15 products show load figures of 1450 pounds at 32 psi and 1550 pounds at 32 psi depending on the tire, while 710-15 products show 1550 pounds at 32 psi. Those figures describe the tire’s rated load at a given pressure, not necessarily the vehicle’s ideal operating pressure in every condition.

The best practice is to use the original owner’s literature as the baseline for vehicle setup and the tire manufacturer’s marking as the tire’s maximum rated reference. A 1963 Willys owner should avoid transferring a pressure assumption from 670-15 to 710-15 or from one brand to another without checking the actual sidewall. Consistent pressure checks matter more on a collector vehicle that may sit between drives.

Before a longer drive in a 1963 Willys, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, and correct cold inflation pressure. Make sure the sidewalls are free from serious weather checking and that the tires are holding air consistently. If the vehicle uses older wheels or tube-type setup practices, valve-stem condition deserves the same attention. Wheel fastener security and general steering feel should also be checked before departure.

That tire inspection should be part of a wider once-over that suits any early-1960s utility vehicle or wagon. Fluids, brakes, lights, charging system health, and cooling condition are all worth confirming before adding distance. A 1963 Willys that has spent much of its life as a hobby vehicle may need more careful preparation than its appearance suggests, and the tires are one of the easiest places to start.
