1946 Crosley Tire Fitment Guide

The 1946 Crosley arrived as America was easing back into civilian production, and Crosley’s appeal centered on compact, economical motoring at a time when most domestic cars were still physically larger and heavier. Small dimensions and light weight made the brand distinctive, and that carries straight into tire selection today. For 1946 Crosley, the choice is unusually straightforward: one model uses one tire size, 450-12, in bias-ply construction on a 12-inch wheel. That simplicity still makes it important to confirm the exact model and decide whether you want a blackwall or narrow whitewall presentation before choosing the tire that matches your car’s look and restoration goals.

Which Tire Size Is Right for Your 1946 Crosley

There is one tire size available for 1946 Crosley, and it is shared across the full model range covered here. That means the main decision is not between different fitment sizes, but between the available bias-ply product styles within the same 12-inch fitment. Understanding that distinction first helps narrow the right tire quickly and keeps the selection aligned with the car’s period character.

450-12Numeric bias-ply

Year(s): 1946Fit(s): 4 Cyl.Construction: Bias PlyRim: 12 in

450-12 is a numeric bias-ply size in which 4.50 refers to the nominal section width and 12 is the wheel diameter in inches. BFGoodrich offers this size with Blackwall and Narrow Whitewall sidewall styles, and the available products are bias-ply throughout. This is the universal 1946 Crosley size rather than a model-specific alternate, so the practical choice comes down to visual style and restoration presentation more than fitment. Buyers aiming to keep the driving feel and appearance in step with the period will usually stay with this bias-ply sizing.

Frequently Asked Questions

These FAQs cover the single 450-12 fitment used on 1946 Crosley models, what that numeric bias-ply size means, how sidewall style affects the car’s look, and what to inspect when a lightly used postwar collector car goes back on the road.

Size Basics & Fitment

What tire sizes fit 1946 Crosley vehicles?

1946 Crosley vehicles covered here use one tire size: 450-12. That size applies to the 1946 Crosley 4 Cyl., and the available tires are bias-ply designs built for a 12-inch wheel. The current product range for this fitment includes blackwall and narrow whitewall versions, both within the same size and construction family.

That makes 1946 Crosley fitment simpler than many postwar cars, because there is no alternate size to sort through at the year-and-make level. The important checks before choosing are the actual wheel diameter on the car, the overall condition of the wheel itself, and whether you want the more understated blackwall look or the more styled narrow whitewall appearance.

What does 450-12 mean on a 1946 Crosley tire?

On a 1946 Crosley tire, 450-12 is a numeric bias-ply size. The 4.50 portion identifies the nominal section width, and the 12 identifies the wheel diameter in inches. Because it is a traditional numeric format rather than a modern metric code, it reflects the sizing language commonly used on small American cars of the period.

Understanding that format helps prevent confusion when comparing reproduction collector tires with newer-looking size systems. A 450-12 should be matched to the correct 12-inch wheel first, then narrowed by sidewall appearance and intended use. If your Crosley still wears period-style wheels, that numeric bias-ply sizing is also part of what keeps the overall stance and visual proportions appropriate to the era.

Do all 1946 Crosley models use the same tire size?

Yes, the 1946 Crosley models covered here use the same tire size: 450-12. There is no split at this year-and-make level between different models or wheel diameters, so the basic fitment path is consistent across the range. All currently listed options in that size are bias-ply tires for 12-inch wheels.

That consistency means the remaining decisions are mostly about presentation and how closely you want to follow period practice. Owners restoring a very stock-looking car may lean toward the sidewall style that best suits the car’s original visual character, while a driver-focused owner still remains within the same size and construction family rather than moving to a different fitment.

Buying the Right Tire

What sidewall styles are available for 1946 Crosley tires?

1946 Crosley tires in 450-12 are available with Blackwall and Narrow Whitewall sidewall styles. Both are offered in the same BFGoodrich bias-ply series, so the underlying fitment and construction remain the same while the visual treatment changes. Blackwall gives the car a simpler, more restrained appearance, while a narrow whitewall adds a little more period flair.

Sidewall choice matters most when the car’s finish level and intended presentation are already set. A modestly trimmed postwar economy car often looks especially natural on blackwalls, but some restorations benefit from the brighter accent of a narrow whitewall. If the Crosley is being built for judged presentation, it is worth checking period photography, club guidance, and the car’s individual history before choosing.

What brands make tires for 1946 Crosley vehicles?

BFGoodrich is the brand represented for 1946 Crosley in the available 450-12 fitment. The options fall within the Silvertown Classic Bias Ply line and include both blackwall and narrow whitewall versions. That gives owners a single brand path within the correct period-style construction rather than multiple brands in competing constructions.

A one-brand selection simplifies the decision because the focus shifts away from comparing competing manufacturers and toward choosing the sidewall appearance that best suits your car. It also keeps the comparison centered on details that matter to collector buyers, such as visual authenticity and expected bias-ply behavior, instead of forcing a tradeoff between radically different tire types.

What is the difference between the BFGoodrich blackwall and whitewall tires for the 1946 Crosley?

For a 1946 Crosley, the BFGoodrich blackwall and BFGoodrich 1.00 Inch Whitewall share the same 450-12 size, the same bias-ply construction, the same 12-inch rim diameter, and the same listed weight. The meaningful difference is the sidewall presentation: one is a plain blackwall and the other adds a narrow white stripe for a more dressed-up period look.

That means the choice is mainly aesthetic rather than a change in size or basic fitment. If you want a simpler, utility-oriented appearance that fits Crosley’s economical character, blackwall is the natural direction. If your goal is a slightly more formal postwar look without changing the tire size itself, the 1.00-inch whitewall gives that visual effect while staying within the same overall specification.

Fitting & Setup

Do 1946 Crosley tires require inner tubes?

The available 1946 Crosley 450-12 products are not marked here with tube-type or tubeless notation. They are bias-ply tires in a collector-vehicle fitment, so the practical question is less about assumption and more about the wheel being used, its design, and its condition. On many vintage applications, tube decisions are tied closely to the wheel itself rather than the sidewall look.

Before fitting new tires, inspect the original wheels carefully for surface condition, sealing surfaces, and any age-related issues that affect air retention. If the car still uses original-style wheels, it is wise to confirm the correct setup with the tire manufacturer or a Crosley specialist before final installation. That is especially important on a small, lightweight postwar car where wheel condition has an outsized effect on confidence and drivability.

Can the original 1946 Crosley wheels be used with all 1946 Crosley tire sizes?

1946 Crosley fitment is straightforward because only one tire size is used here: 450-12. That size mounts on a 12-inch wheel, so there is no year-and-make alternate size requiring a different wheel diameter. The original wheel question is therefore about confirming condition and true wheel diameter rather than sorting between multiple tire diameters.

If your Crosley still has its original wheels, check for straightness, corrosion, bead-seat condition, and any past repairs before mounting fresh tires. Collector cars that have sat for long periods often need wheel attention even when the tire size itself is simple. Verifying the wheel first helps avoid chasing ride or sealing issues that are really wheel-related rather than tire-related.

Maintenance, Storage & Longevity

How should I store a 1946 Crosley when the tires are fitted?

A 1946 Crosley should be stored away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can accelerate sidewall aging. Keep the car in a cool, dry space, maintain proper inflation, and move it periodically so the tires are not loaded in one spot for months at a time. Bias-ply tires are especially prone to flat-spotting during long static storage.

For a car that will sit through a season, many owners either roll it occasionally or support it in a way that reduces continuous load while still keeping the suspension appropriately settled. The smaller tire size used on a Crosley makes good storage practice even more important, because any pressure loss or flat-spotting tends to show up quickly once the car goes back into use.

How long do tires on a 1946 Crosley typically last?

Tires on a 1946 Crosley are better judged by age and condition than by miles alone, because collector cars often see very limited annual use. A sound rule is to evaluate them closely once they reach the five- to seven-year range and to treat roughly ten years as a point where replacement deserves serious consideration, even if the tread still looks good. The tire’s date code helps establish actual age.

That approach matters on lightly driven postwar cars because rubber compounds can age out long before the tire appears worn in the usual sense. Sidewall checking, hardening, and long-term storage damage can all affect a tire that still has ample tread depth. If the Crosley’s service history is unclear, age-based replacement is usually the safer path than trusting appearance alone.

How often should tires on a 1946 Crosley be inspected?

Tires on a 1946 Crosley should be inspected before every drive and again before any longer outing. Look for visible sidewall cracking, tread separation, bulges, punctures, uneven wear, and pressure loss. On a collector car, it is also smart to inspect the spare, because a decades-old spare can look untouched while still being too old for dependable road use.

Frequent inspection is especially worthwhile on vintage small cars because they are often driven only occasionally, and long intervals between outings can hide slow changes in condition. A short walk-around before departure catches the common problems that develop in storage. If the car uses tubes or older valve hardware, make those components part of the routine inspection as well rather than focusing only on the tread.

Restoration & Authenticity

What tires were originally fitted to the 1946 Crosley 4 Cyl.?

A 1946 Crosley 4 Cyl. would have been fitted in period with bias-ply tires, and the year-and-make fitment used here is 450-12. That aligns with what buyers would expect from an immediate postwar American compact, when bias-ply construction was still the standard across the market. Original-equipment branding could vary by market and production details, so the key authenticity points are the correct size, period construction, and appropriate sidewall style.

For most restorations, getting those fundamentals right matters more than chasing a brand name that may not be verifiable for every individual car. If you are preparing a highly judged Crosley, compare factory literature, period photos, and marque-club guidance before finalizing the sidewall presentation. That extra step helps ensure the tire complements the car’s trim level and intended historical presentation.

Does correct tire fitment matter for showing a 1946 Crosley?

Correct tire fitment does matter when showing a 1946 Crosley, especially in events where authenticity is judged closely. Size, construction type, and sidewall style all contribute to whether the car looks era-appropriate. A modern-looking fitment or an overly broad sidewall treatment can stand out on a small postwar economy car even when the overall restoration is otherwise strong.

On a Crosley, tires are visually important because the car’s compact proportions make them easy to notice. Staying with the proper 450-12 bias-ply format keeps the wheel opening and stance in character, while the blackwall-versus-narrow-whitewall choice should match the way the rest of the car is presented. If you are building toward judging standards, check club or event rules before making the final call.

What is the difference between blackwall and narrow whitewall tires for a 1946 Crosley restoration?

For a 1946 Crosley restoration, the blackwall and narrow whitewall versions of 450-12 share the same basic fitment and bias-ply construction. The difference is visual authenticity and presentation. Blackwall tends to emphasize Crosley’s economical, practical personality, while a narrow whitewall adds a slightly more polished postwar look without moving outside the period-style bias-ply format.

Choosing between them depends on the story you want the finished car to tell. A straightforward, factory-minded restoration often looks very natural on blackwalls, while a more accessorized or presentation-focused build may benefit from the extra contrast of the whitewall. Reviewing period advertisements and surviving original cars can be helpful, because subtle sidewall decisions often influence the finished impression more than owners expect.

Safety & Road Use

Are 1946 Crosley tires safe for highway driving?

1946 Crosley tires in the listed 450-12 fitment are period-style bias-ply tires, and highway use depends on the tire’s condition, age, inflation, and proper installation as much as the basic size itself. A sound, fresh tire in the correct fitment can certainly be used on public roads, but a 1946 Crosley is still a very small postwar car whose brakes, suspension design, and overall driving character deserve equal respect.

That means the road-speed question should be considered as a whole-vehicle issue rather than a tire-only issue. Even with fresh tires, drivers should leave room, avoid overdriving the car, and remember that a lightweight 1940s compact does not behave like a modern vehicle in crosswinds, braking, or emergency maneuvers. Tire safety starts with the right fitment, but it ends with realistic expectations behind the wheel.

What inflation pressure should I use for 1946 Crosley tires?

Inflation pressure for 1946 Crosley tires should be set by the vehicle’s factory recommendations and then checked against the tire manufacturer’s guidance for the specific 450-12 product you are using. The available fitment here is 450-12 bias-ply, but pressure should not be guessed from size alone or copied from an unrelated vintage car. Correct pressure is part of both handling feel and tread life on a lightweight vehicle.

Using too little pressure can make a small bias-ply tire run hotter and feel less stable, while too much can affect ride quality and footprint. Start with the owner’s manual or marque literature for the vehicle side of the equation, then confirm that the chosen reproduction tire is being used within its intended operating range. Keeping a regular pressure check schedule matters more than making one adjustment and forgetting about it.

What should I check before taking a 1946 Crosley on a longer drive?

Before taking a 1946 Crosley on a longer drive, inspect all tires for cracking, cuts, bulges, irregular wear, proper inflation, and secure valve hardware. Include the spare in that inspection, because an old spare is often the weak link on collector cars. Look over the wheels as well, especially if the car has spent long periods in storage or has recently returned to service.

A longer trip in a postwar compact also calls for a broader mechanical check beyond the tires. Brakes, steering, wheel bearings, lights, fluids, and cooling system condition all matter on a car of this age. When the tire fitment is already simple, as it is on a 1946 Crosley, reliability on the road usually comes down to careful overall preparation rather than choosing among multiple tire sizes.
