1950 Willys 4-63 & 6-63 Wagon Tires

The primary tire size for a 1950 Willys 4-63 & 6-63 Wagon is 670-15. That is a vintage numeric bias-ply size used on a 15-inch rim, and it is the core fitment to start with when replacing tires on this model.

Because this wagon uses one main size, the next step is choosing the right version of 670-15 rather than sorting through multiple primary fitments. Check the actual wheel diameter, compare the tire’s rim-width requirement to your wheel, and confirm that any older wheel, hubcap, or brake setup has not been changed over the years.

The 1950 Willys 4-63 & 6-63 Wagon uses a 15-inch rim with its primary 670-15 tire fitment. That rim diameter is central to both traditional bias-ply replacement and any radial-equivalent comparison for this vehicle.

Rim diameter alone does not settle the fitment question, especially on an older vehicle. Wheel width should also match the tire being considered, and that matters because available 670-15 products do not all share the same rim-width specification. A wagon with replacement wheels should be measured before choosing a tire by appearance alone.

Yes. The 1950 Willys 4-63 & 6-63 Wagon Base uses the same 670-15 bias-ply tire size as the overall model fitment. That keeps the basic replacement path simple for owners working with a stock-type wheel and tire setup.

Even with shared size fitment, tire choice can still vary depending on the look and use of the wagon. A blackwall keeps a more utilitarian presentation, while narrow and wide whitewalls create a more restoration-oriented appearance. It is still worth confirming wheel width and overall clearance if the wagon has seen wheel, brake, or suspension changes.

For the 1950 Willys 4-63 & 6-63 Wagon, 670-15 is the primary bias-ply tire size. In this vintage numeric format, the size refers to a traditional bias-ply fitment rather than a modern radial construction.

That matters because tire construction affects both appearance and how the wagon feels on the road. Owners aiming for a period-style presentation often stay with bias-ply, while others compare radial alternatives for road use. Either way, the wheel’s diameter and width should match the tire being considered before any change in construction is made.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial that keeps a more traditional visual style.

These sizes are useful alternatives, but they should be evaluated rather than assumed. The recommended rim-width range for the equivalents is 5 to 7 inches, and actual fit should also account for wheel condition, vehicle clearance, and how closely the owner wants to stay to a period-style stance and sidewall appearance.

Start with the wheel itself. A 1950 Willys 4-63 & 6-63 Wagon uses a 15-inch rim with its 670-15 bias-ply tire, and radial equivalents should be checked against wheel diameter, wheel width, and the vehicle’s available clearance before making the switch.

Road-use goals matter just as much as fitment. A bias-look radial such as 670R15 keeps a more traditional presentation, while 195R15, P205/75R15, and P215/70R15 move into modern sizing conventions. Any wagon with replacement wheels, suspension work, or age-related steering and suspension wear should be inspected carefully before changing construction.

Start with the correct primary size, which is 670-15, then compare the tire’s construction, sidewall treatment, and rim-width specification. For this Willys wagon, the main decision is whether the goal is a traditional bias-ply setup with a utility look or a more restoration-oriented whitewall presentation.

Brand and series differences also matter because the available 670-15 assortment spans several classic lines. Some tires are blackwall, some use narrow whitewalls, and others use wide whitewalls, so the finished appearance can change significantly. Wheel width, intended road use, and the overall look of the wagon should guide the final choice.

The available 670-15 tires for a 1950 Willys 4-63 & 6-63 Wagon include blackwall, narrow whitewall, and wide whitewall sidewall styles. That gives the owner a broad range of visual options while staying within the wagon’s primary tire size.

A blackwall generally suits a more work-oriented or understated postwar appearance, while whitewall choices create a more dressed, restoration-minded look. Whitewall width also varies, so the final impression can shift from subtle to very prominent. It helps to match the sidewall style to the wagon’s trim level, wheel treatment, and intended finish rather than choosing by size alone.

The 1950 Willys 4-63 & 6-63 Wagon has 670-15 tire options from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several classic bias-ply series and sidewall treatments.

The most useful comparison is not brand name alone, but how each tire is configured. Some focus on blackwall utility style, some on narrow or wide whitewall appearance, and some differ in rim-width guidance or load specification. Choosing the right one means comparing the wheel you have, the look you want, and how the wagon will actually be driven.

A period-style starting point for a 1950 Willys 4-63 & 6-63 Wagon is the primary 670-15 bias-ply size on a 15-inch rim. Staying with that construction preserves the traditional profile and visual character associated with a postwar utility wagon.

The final look depends on sidewall treatment. Blackwall tires keep a more functional, work-ready appearance, while narrow and wide whitewalls give the wagon a more restored and dressier presentation. When exact originality matters, it is smart to compare the tire choice against surviving photographs, marque-club references, or other vehicle-specific historical guidance.

Tire construction changes the visual impression of a restored 1950 Willys 4-63 & 6-63 Wagon more than many owners expect. A 670-15 bias-ply keeps the wagon in its original-era sizing language, while a radial alternative can shift the look even if the wheel diameter remains the same.

That difference matters most when the goal is a restoration-oriented finish. A bias-look radial such as 670R15 can help preserve a more traditional presentation, while metric and P-metric radials look more modern in format. The best choice depends on whether the priority is historic appearance, road use, or a balance between the two.

Yes. Modifications can change tire fitment on a 1950 Willys 4-63 & 6-63 Wagon even when the tire size being considered is still 670-15 or one of its radial equivalents. Replacement wheels, brake changes, altered ride height, or steering and suspension work can all affect the available space and wheel compatibility.

An older wagon often has decades of changes behind it, so the actual setup should be checked before selecting by size alone. Measure the wheel diameter and width, inspect clearance at full steering lock, and look for contact points near springs, fenders, and inner wheel housings. That matters especially when comparing bias-ply and radial alternatives.

Before road use, inspect the wheels, valve stems, lug hardware, and overall wheel condition, then confirm tire pressure and look over the tire for any mounting damage or irregular seating. On a 1950 Willys 4-63 & 6-63 Wagon, it also makes sense to verify steering and suspension condition before the first drive.

A short, careful test drive is the best next step. Listen for rubbing, feel for pull or vibration, and recheck clearance after the suspension has settled. Older vehicles can reveal worn tie-rod ends, loose bearings, or alignment issues only once they are back on the road, so the first miles should be treated as a setup check.

Collector-use 670-15 tires on a 1950 Willys 4-63 & 6-63 Wagon should be inspected regularly for air loss, cracking, cuts, tread wear, and any bulges or flat spotting from long storage. Tire pressure should be checked before use, especially on a vehicle that spends more time parked than driven.

Storage habits matter as much as mileage. Keeping the wagon away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires over time. It also helps to move the vehicle periodically or drive it enough to avoid long-term flat spotting, then inspect the tires again before any longer outing or highway use.
