1947 Willys Tire Fitment Guide

1947 Willys vehicles in this guide use two tire sizes: 600-15 and 670-15, and both are listed for the 1947 Willys Wagon. Both are bias-ply fitments that mount on 15-inch wheels. Available rim-width ranges vary by tire, with 600-15 products covering 4.00 to 5.00 inches depending on the version, and 670-15 products covering 4.50 to 6.00 inches where that range is stated.

That means the first thing to verify on a 1947 Willys Wagon is the actual tire size already fitted or the wheel width you plan to use, not simply the make and year. Since both sizes belong to the same Wagon model, the decision usually comes down to preserving the size your vehicle has historically used or selecting the look and stance you prefer while staying within the wheel's compatible width range.

On a 1947 Willys, 600-15 is a traditional numeric bias-ply size. The 600 portion is the nominal section width designation used in older American tire sizing, and the 15 identifies the wheel diameter in inches. It does not read like a modern metric radial size, and it does not include a separate aspect ratio the way a newer P-metric tire would.

That matters because a 1947 Willys Wagon owner should evaluate 600-15 as an era-correct bias-ply fitment rather than trying to interpret it through modern sizing logic. When comparing products in this size, focus on wheel-width compatibility, sidewall style, and the overall look you want on the vehicle. For many restorations, the tire code itself tells you you are working with a period-style specification rather than a later radial convention.

On a 1947 Willys, 670-15 is another numeric bias-ply size. The 670 identifies the nominal section width designation in the older numbering system, while the 15 again refers to a 15-inch wheel diameter. Like 600-15, it is an older American size code and should not be interpreted as a modern metric tire with width and aspect ratio written in millimeters and percentages.

For a 1947 Willys Wagon owner, that means 670-15 is best understood as a larger period-style bias-ply choice within the same 15-inch wheel family. It is also the size with the broader brand and sidewall selection here, which can be helpful if you are tailoring the Wagon toward a more upscale whitewall appearance or a simpler blackwall presentation. The key is confirming that the wheel width suits the specific 670-15 tire you choose.

Both 600-15 and 670-15 are bias-ply options for the 1947 Willys Wagon, so this is not a bias-ply-versus-radial decision. The main difference is the size itself, with both fitting 15-inch wheels but carrying different wheel-width requirements depending on the individual tire. The 600-15 selection is smaller and simpler in range, while 670-15 has more available brand and sidewall choices.

Most owners should start by matching the size already associated with their Wagon or by checking which wheel width they actually have before deciding. If your priority is preserving a specific period look, the sidewall presentation may drive the decision as much as the size code. If your Wagon is being restored with close attention to stance, wheel fill, and overall appearance, choosing between 600-15 and 670-15 should be done before narrowing to a specific brand.

1947 Willys tires are available in both blackwall and wide whitewall styles. In 600-15, BFGoodrich offers a blackwall and a 2.625-inch wide whitewall version. In 670-15, available choices include blackwalls from Firestone and Universal Vintage Tire, plus wide whitewall versions from US Royal and Coker Classic.

That gives a 1947 Willys Wagon owner room to tailor the vehicle's presentation without leaving the correct bias-ply era. Blackwalls usually suit a more utilitarian or work-ready look, which fits the Wagon's practical roots especially well. Wide whitewalls can shift the same vehicle toward a more polished postwar passenger-car appearance, which often appeals to restorers who want the Wagon to read less like a service vehicle and more like a family touring machine.

Several brands cover 1947 Willys fitments. The 600-15 size is available from BFGoodrich, while 670-15 is offered by Firestone, US Royal, Coker Classic, and Universal Vintage Tire. All of the available options for these Willys applications are bias-ply tires built around the period style that suits a 1947 vehicle.

Brand choice on a 1947 Willys Wagon often comes down to the sidewall appearance you want and the exact size you need rather than a completely different type of fitment. If you already know you need 600-15, your choices are narrower and centered on BFGoodrich styling options. If your Wagon uses 670-15, you have a broader mix of blackwall and wide whitewall offerings, which can make it easier to match the vehicle's restoration theme.

Rim width depends on the tire size and, in some cases, the specific product chosen for a 1947 Willys. For 600-15, listed fitments cover 4.00 to 4.50 inches on one version and 4.50 to 5.00 inches on another. For 670-15, listed ranges include 4.50 to 5.00 inches and 5.00 to 6.00 inches, depending on the tire.

That variation is important because two tires with the same nominal size can still call for slightly different wheel widths. Before fitting a tire to a 1947 Willys Wagon, measure the wheel or confirm its width through the wheel itself or trusted vehicle records. Once the wheel width is known, you can narrow the tire choice confidently and avoid selecting a product that is correct in diameter but mismatched to the rim.

Both 600-15 and 670-15 for the 1947 Willys Wagon mount on 15-inch wheels, so they share the same wheel diameter. That means the original 15-inch Willys wheel can be diameter-compatible with either size. The limiting factor is wheel width, because the available products span different recommended rim-width ranges within the same 15-inch family.

A Wagon owner should treat wheel diameter and wheel width as two separate checks before moving between sizes. If the wheel falls within the approved width range for the specific 600-15 or 670-15 tire you are considering, the size may be workable on the original wheel. If the wheel is too narrow or too wide for that product, the size code alone is not enough to confirm suitability.

A 1947 Willys should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Because the available tires for 1947 Willys are bias-ply, long stationary periods can encourage flat-spotting more readily than many later radial designs. Clean floors, stable temperature, and protection from moisture all help preserve the casing and sidewall finish.

Moving the vehicle periodically or taking weight off the tires during longer storage can help the tires keep their shape. Keep inflation pressure checked during the off-season, and avoid leaving the Wagon parked for months with underinflated tires. If the vehicle is stored with a wide whitewall set, routine gentle cleaning also helps preserve the cosmetic edge that is often central to the look of a restored postwar Willys.

Tire life on a 1947 Willys is usually judged more by age and condition than by mileage, because collector vehicles often see limited annual use. A good working rule is to begin close inspection by about five to seven years of service and to treat roughly ten years as a point where replacement deserves serious consideration, even if tread depth still looks serviceable. The DOT date code on the tire helps establish age.

That approach matters on a 1947 Willys Wagon because a lightly driven vehicle can still age its tires through time, heat cycles, and storage conditions. A tire that looks presentable at a glance may still be too old for confident road use, especially if it has sidewall cracking or persistent vibration. Regular age tracking is more useful than waiting for visible wear alone on a low-mileage collector vehicle.

Tires on a 1947 Willys should be inspected before every drive, and they deserve an extra-thorough check before any extended outing. Look for cracks in the sidewall, tread separation, cuts, bulges, irregular wear, and any sign that the tire is losing pressure between uses. Since these are older-style bias-ply fitments, changes in shape or ride feel should be taken seriously rather than dismissed as normal vintage behavior.

A quick routine inspection can prevent a small issue from turning into a roadside problem on a postwar Wagon. Check the spare as well, because many collector vehicles still carry an aged spare that matches the car visually but not necessarily in usable condition. If your Willys has been sitting, inspect each tire after the first few miles too, since long storage can reveal flat spots or age-related issues once the vehicle is back in motion.

A 1947 Willys Wagon would have originally belonged to the bias-ply era, and the available fitments here reflect that with 600-15 and 670-15 bias-ply offerings. That aligns with what a buyer would expect for an American utility wagon in the immediate postwar period. Original-equipment branding could vary by market, dealer, and replacement history, so the most reliable starting point is the correct size and construction type rather than assuming one universal brand.

For a restoration-minded owner, the most important first step is confirming which size is appropriate for the specific Wagon and wheel set you are recreating. Once size and construction are right, sidewall treatment becomes the next authenticity choice, especially if you are aiming for a work-oriented blackwall look or a more dressed-up wide whitewall presentation. Marque specialists and Willys clubs can help refine those finer historical details for a particular vehicle.

Correct tire fitment matters on a 1947 Willys because show judging often considers size, construction type, and sidewall appearance as part of the vehicle's overall authenticity. On a postwar Wagon, a period-style bias-ply tire supports the visual stance and era-correct sidewall profile expected from the vehicle. A mismatched size or a sidewall style that does not suit the restoration theme can stand out even to casual observers.

That does not mean every event uses the same standard, but it does mean your tire choice should match the level of authenticity you want the vehicle to present. If the Wagon is being judged for originality, staying with a proper bias-ply size and an era-appropriate sidewall style is the safer path. For event-specific rules, consult the club or judging body involved, since they may weigh blackwall versus whitewall presentation differently.

The 670-15 offerings for the 1947 Willys differ by brand, sidewall style, and in some cases rated load and wheel-width compatibility. Firestone and Universal Vintage Tire offer blackwall versions, while US Royal and Coker Classic provide wide whitewall alternatives. Listed load ratings in this size include 1450 pounds at 32 psi and 1550 pounds at 32 psi where specified, and wheel-width fitment ranges span from 4.50 to 6.00 inches depending on the tire.

That means a 1947 Willys Wagon owner should compare 670-15 choices on more than appearance alone. A wide whitewall may suit a polished restoration, while a blackwall can better reinforce the Wagon's functional roots. At the same time, the wheel width on the vehicle has to line up with the tire's approved range, so the most visually appealing 670-15 option is only the right choice if it also matches the wheel you plan to run.

1947 Willys tires can be suitable for normal road use when they are the correct size, in sound condition, and properly fitted to compatible wheels. The available fitments here are bias-ply tires, which deliver the period-style driving feel expected from a postwar Wagon rather than the response characteristics of a modern radial. On a vehicle of this age, overall mechanical condition often matters at least as much as the tire itself when planning highway use.

A 1947 Willys Wagon headed onto faster roads should have its tires, alignment, steering components, suspension, and brakes evaluated as a system. Even a properly selected bias-ply tire cannot compensate for worn kingpins, loose steering, or neglected brake hardware. If the Wagon feels unsettled at speed, the answer is to inspect the chassis and the tire setup together rather than assuming the size alone is the cause.

Several available 1947 Willys tires list rated load and pressure figures that provide an upper reference for the tire itself. In 600-15, available products carry 1150 pounds at 32 psi. In 670-15, listed products carry 1450 pounds at 32 psi or 1550 pounds at 32 psi depending on the tire. Those figures describe the tire's rated load at that pressure, not necessarily the factory operating pressure Willys originally recommended for the Wagon.

For actual on-vehicle use, start with the original Willys guidance if you have it, then make sure your chosen tire's own rating is respected. Do not transfer one pressure assumption from 600-15 to 670-15 or from one brand to another just because the wheel diameter is the same. Inflation should match the vehicle's intended use, weight, and the specific tire fitted, with pressure checked cold before driving.

Before a longer drive in a 1947 Willys, inspect each tire for cracking, cuts, bulges, uneven wear, and any sign of age-related hardening. Confirm cold inflation pressure, make sure the valve stems are in good shape, and look over the spare as carefully as the four road tires. Because these are vintage-style bias-ply fitments, any persistent shimmy, pull, or thump deserves attention before the trip begins.

A longer outing in a 1947 Willys Wagon should also include a broader mechanical check of steering, brakes, wheel bearings, and suspension condition. Vintage vehicles place more demand on the driver's preparation than modern cars, and tires are only one part of that picture. When the tire size is correct, the wheel width is appropriate, and the vehicle has been inspected as a whole, the Wagon is in a much better position for dependable road use.
