1957 Willys 226 Tires

The 1957 Willys 226 uses two different primary tire sizes depending on configuration. The 4WD 6 Cyl. uses a 700-16 bias-ply tire, while the 4x2 6 Cyl. uses a 670-15 bias-ply tire. Those are not just alternate sizes for the same setup, because they also correspond to different wheel diameters.

The practical first step is confirming exactly which sub-model is in front of you and then checking the actual wheel diameter on the vehicle. A Willys that has been modified over the years may no longer wear its original wheel setup, so matching the tire to the current wheel and the vehicle’s intended use is more important than assuming every 1957 Willys 226 takes the same size.

A 1957 Willys 226 uses either a 16-inch rim or a 15-inch rim, depending on sub-model. The 700-16 tire is paired with the 4WD 6 Cyl. configuration, and the 670-15 tire is paired with the 4x2 6 Cyl. configuration. Rim diameter is the key separator between the two tire sizes.

That means wheel diameter should be verified before comparing tire options, especially on an older vehicle that may have had wheels changed during its life. Rim width also matters once the diameter is confirmed, since available products within these sizes can carry different rim-width recommendations. Starting with the wheel already on the vehicle helps narrow the correct path quickly.

No, the covered 1957 Willys 226 sub-models do not share one common tire size. The 4WD 6 Cyl. uses 700-16 bias-ply tires, while the 4x2 6 Cyl. uses 670-15 bias-ply tires. Each size belongs to its own wheel-diameter setup, so the difference is more significant than a minor variation within one rim size.

That split affects the entire buying decision, including wheel confirmation, sidewall choices, and whether radial equivalents are even part of the conversation. The 670-15 fitment has radial-equivalent options, while the 700-16 fitment here is centered on bias-ply products. Identifying the exact sub-model prevents ordering a tire that matches the vehicle name but not the actual wheel and configuration.

For the 1957 Willys 226, 670-15 is a primary bias-ply tire size on the 4x2 6 Cyl. configuration. The size itself is a vintage numeric bias-ply designation, and the available primary fitment products in that size are bias-ply tires. Radial choices for this vehicle are treated separately as equivalents rather than as the original primary construction.

That distinction matters if the goal is to keep the vehicle close to its original-type tire construction or period-style appearance. A radial alternative can still be considered, but it should be evaluated as a conversion decision rather than a simple one-for-one swap. Wheel size, wheel width, and clearance around suspension and bodywork should all be confirmed before changing construction.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those options cover several different sizing conventions: 195R15 is a Euro-metric 80-series style radial, P205/75R15 is a 75-series P-metric radial, P215/70R15 is a 70-series P-metric radial, and 670R15 is a bias-look radial.

Each of those sizes should be treated as an alternative to compare rather than an automatic interchange. The recommended rim-width range for these radial equivalents is 5 to 7 inches, which gives a useful starting point, but overall fit still depends on the actual wheel, the vehicle’s present stance, and available clearance at steering lock and through suspension movement.

Start by confirming that the Willys in question is the 4x2 6 Cyl. using 670-15, since that is the fitment with stated radial equivalents. Then verify the actual wheel diameter and width on the vehicle, because radial-equivalent choices such as 195R15, P205/75R15, P215/70R15, and 670R15 still need to match the wheel and work within the vehicle’s space.

A good conversion check also includes looking at steering clearance, fender clearance, suspension condition, and how the vehicle will be driven. Construction changes can alter the overall feel and visual presentation even when the size is in the right range. On a long-owned collector vehicle, it is also worth confirming that no previous owner changed wheels, ride height, or axle setup.

Begin with the exact configuration, because the 1957 Willys 226 does not use one universal tire size. The 4WD 6 Cyl. takes 700-16 bias-ply tires, while the 4x2 6 Cyl. takes 670-15 bias-ply tires. After size and wheel diameter are confirmed, the next decisions are usually construction retention, sidewall appearance, and whether the vehicle is being kept closer to working-truck character or a more dressed period-style look.

Product differences become meaningful once the correct size is fixed. Some options lean toward blackwall utility styling, while others offer narrow or wide whitewalls and more restoration-oriented presentation. Rim-width guidance, load figures where stated, and tire series can also help narrow the field, especially if the Willys is used for regular road driving rather than occasional display.

Sidewall choices for the 1957 Willys 226 include blackwall, narrow whitewall, and wide whitewall, depending on tire size and product selection. The 700-16 fitment is offered mainly in blackwall and wide whitewall forms, while the 670-15 fitment has the broadest spread of blackwall, narrow whitewall, and wide whitewall designs across multiple series and brands.

That makes sidewall selection as much an appearance decision as a fitment decision once the correct size is established. A blackwall tire tends to suit a more functional or truck-oriented presentation, while whitewall treatments move the look toward a more finished late-1950s style. Sidewall style should be chosen after confirming size, wheel diameter, and the overall direction of the vehicle.

Brands available across the 1957 Willys 226 tire sizes include Firestone, BFGoodrich, Goodyear, US Royal, Universal Vintage Tire, Lester, Avon, Excelsior, Coker Classic, Tornel, and STA. Not every brand appears in both sizes, so the exact brand pool depends on whether the vehicle uses 700-16 or 670-15.

Brand choice is only one part of the decision. It should be considered alongside the correct tire size, the intended look, the tire series, and whether the Willys is meant to present as a work-focused vehicle or a more restoration-oriented build. Looking at the brand within the context of sidewall style, rim-width fit, and stated load characteristics is more useful than choosing by name alone.

A period-style choice starts with the correct primary size for the specific 1957 Willys 226 configuration: 700-16 for the 4WD 6 Cyl. and 670-15 for the 4x2 6 Cyl. From there, a bias-ply tire keeps the vehicle closer to the construction type associated with its original era, while the sidewall treatment helps shape whether the finished look feels work-oriented or more polished.

Blackwall tires usually support a simpler utility presentation, especially on the 700-16 setup, while narrow and wide whitewalls create a more styled late-1950s look on 670-15. Exact originality can vary by vehicle history and equipment, so owners pursuing a strict restoration standard should compare tire choices against marque references, historical photos, or other vehicle-specific documentation before finalizing appearance details.

Tire construction changes more than road feel on a restored 1957 Willys 226; it also changes the vehicle’s visual character. A bias-ply tire preserves the traditional shape and presentation associated with the period, while a radial equivalent on the 670-15 setup can shift the look slightly even when the overall intent remains vintage. That difference becomes more noticeable on a carefully detailed restoration.

The practical question is how closely the owner wants to stay with an era-consistent appearance versus a more modernized road-use setup. A bias-look radial such as 670R15 can be useful when a radial is being considered without abandoning a traditional visual theme. Even then, wheel width, vehicle stance, and surrounding details should be reviewed so the finished appearance stays cohesive.

Yes, modifications can affect tire fitment on a 1957 Willys 226, even when the tire size itself is correct for the original configuration. Changes to wheels, ride height, springs, steering components, or body clearance can all influence how a 700-16 or 670-15 tire sits and moves on the vehicle. That becomes especially important on older Willys models that may have been altered for utility use or restoration.

The safest approach is to inspect the actual wheel diameter and width already on the vehicle, then check clearance at full steering lock and through suspension movement. A Willys that has aftermarket wheels or a changed stance may need a closer fitment review before choosing among available products or considering a 670-15 radial equivalent. Small setup changes can matter on a vintage chassis.

Before road use, inspect the wheels for correct diameter, condition, and secure mounting, then verify that the new tires match the vehicle’s actual setup. It is also worth checking for clearance around fenders, suspension parts, and steering components, especially if the Willys has been modified or has not been driven regularly. New tires deserve the same attention as the rest of the rolling chassis.

A broader pre-drive inspection should include air pressure, lug torque, visible sidewall condition, and any signs of rubbing during slow steering movement. On a collector vehicle, wheel bearings, brakes, and steering linkage condition are just as important as the tires themselves. A short local drive followed by a second visual check is a smart way to confirm everything has settled properly.

Collector-car tire care for a 1957 Willys 226 starts with regular pressure checks, visual inspections, and attention to age-related condition even when tread still looks usable. Bias-ply tires on a low-mileage vehicle can spend long periods sitting, so sidewall cracking, flat spotting, bulges, and slow air loss deserve close attention. Clean, dry storage conditions also help protect the tires between drives.

Periodic movement of the vehicle can help reduce long-term stress from sitting in one position, and keeping it away from prolonged sunlight, moisture, and ozone sources is beneficial. The wheels should also be checked occasionally for corrosion or damage that could affect sealing or mounting. A tire that looks presentable on a collector Willys still needs routine inspection before being trusted on the road.
