Crosley 4 Cyl. Tires
Crosley 4 Cyl. models from 1946 to 1947 belong to a distinctive postwar chapter in American small-car history, when compact dimensions, light weight, and economical operation set them apart from the larger domestic cars of the day. The Crosley 4 Cyl. was built for practical motoring, but today it occupies a very different place as a collector car that depends on correct period-size tires to preserve its character and stance. Tire selection is not difficult here, but it still matters because these small postwar cars use a specialized size that modern shoppers may not recognize at a glance. Before choosing a tire, confirm that the car still carries its correct 12-inch wheels.
Crosley 4 Cyl. Tire Size Guide
Crosley 4 Cyl. models from 1946 to 1947 use one tire size: 450-12. This is a numeric bias-ply size, where 450 indicates the nominal section width with the decimal omitted, or roughly 4.50 inches, and 12 is the rim diameter in inches. Available products for this size use a 12-inch rim and are offered in BFGoodrich Silvertown Classic Bias Ply form. Blackwall and narrow whitewall versions are available for the same size. A tube is required.

Frequently Asked Questions
The FAQ below focuses on the single 450-12 fitment used on the Crosley 4 Cyl., how that numeric size should be read, what bias-ply construction means for use, and how to care for low-mileage collector tires over time.
Size Basics & Fitment
The Crosley 4 Cyl. uses one tire size across the years listed here: 450-12 for both 1946 and 1947. The available products for that size are bias-ply tires built for a 12-inch rim, with blackwall and narrow whitewall versions offered in the same basic size.
That makes selection more straightforward than on many collector cars, but the car should still be checked for its actual wheel diameter before a tire is chosen. A Crosley that has been modified, stored with mismatched parts, or restored from multiple donor cars can end up with something other than its expected wheel, so verifying the wheel itself remains the right first step.
On a Crosley 4 Cyl., 450-12 is a numeric bias-ply tire size. The 450 indicates a nominal section width of about 4.50 inches, with the decimal omitted in older sizing practice, and the 12 identifies the rim diameter in inches.
That older style of sizing is common on mid-century collector vehicles and does not read like a modern metric radial code. When a Crosley owner sees 450-12 on the sidewall or in a parts reference, it should be understood as a period bias-ply size intended for a 12-inch wheel rather than as a modern low-profile or radial equivalent.
The available Crosley 4 Cyl. products in 450-12 are bias-ply tires, and a tube is required. That follows the normal practice for collector-era bias-ply fitments in this size range unless a tire is specifically identified otherwise.
Tube fitment matters because it affects how the tire seals, how the assembly is installed, and what components should be renewed during a restoration. When replacing tires on a Crosley 4 Cyl., the tube and related hardware should be evaluated at the same time so the finished wheel-and-tire assembly matches the intended construction.
Buying the Right Tire
For a 1946 or 1947 Crosley 4 Cyl., the listed tire size is 450-12, used with a 12-inch rim. Since both years share the same size, the main confirmation points are the sidewall marking on the current tire, the wheel diameter, and the car's restoration history.
That matters most on cars that have sat for decades or changed hands several times, because small collector cars are often pieced together with substitute wheels. Matching the year alone is not enough if the wheels have been swapped, so compare the actual wheel and existing tire markings before settling on blackwall or narrow whitewall appearance.
Crosley 4 Cyl. tires in 450-12 are available with two sidewall styles: Blackwall and Narrow Whitewall. Both are offered within the same BFGoodrich Silvertown Classic Bias Ply series, so the construction and basic fitment stay the same while the appearance changes.
That gives a Crosley owner a choice between a simpler utilitarian look and a more dressed-up period presentation. For a restoration, the right sidewall style usually depends on how the car is being finished visually and what reference material supports its intended presentation, especially if the goal is to match a certain showroom or club-judging look.
The Crosley 4 Cyl. products listed here are not identified as made-to-order items. The current 450-12 options are standard bias-ply offerings in the available series and sidewall styles rather than special-run listings carrying that product attribute.
Even so, collector-tire buyers should still focus first on selecting the correct size, construction, and appearance for the car. On a compact postwar vehicle like the Crosley 4 Cyl., getting the correct 12-inch fitment and the preferred sidewall treatment right will matter more than assuming every vintage tire category is handled the same way.
Maintenance & Longevity
A Crosley 4 Cyl. should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large swings in temperature. Bias-ply tires benefit from being kept properly inflated during storage so the casing is not left under-inflated and distorted for long periods.
If the car will sit for extended stretches, moving it occasionally can help avoid flat spotting, and many owners reduce long-term stress by using stands placed correctly under the vehicle. Good storage habits matter on a light collector car because long idle periods often age tires out well before tread is used up.
Tires on a Crosley 4 Cyl. should be inspected before regular driving and again after any long storage period. A collector bias-ply tire should be checked for cracking, sidewall damage, irregular wear, embedded debris, valve condition, and any sign that the tube or bead area may need attention.
Frequent inspection is especially worthwhile on a car that sees limited mileage, because age-related issues often appear before major tread wear does. A quick pre-drive look at inflation, visible condition, and how the tire is sitting on the wheel can catch problems early and help prevent damage to hard-to-replace vintage components.
Tires on a Crosley 4 Cyl. should be replaced when age, cracking, casing deterioration, persistent air loss, or physical damage becomes evident, even if the tread still looks usable. Collector-car tires often age out long before they wear out, particularly on lightly driven vehicles that spend most of their lives parked.
That rule is important with bias-ply construction because outward appearance alone does not always reveal the full condition of the tire and tube assembly. If the car has been stored for years or its tire age is uncertain, replacement should be considered part of recommissioning rather than postponed until the tread looks visibly worn.
Restoration & Authenticity
The listed fitment for the Crosley 4 Cyl. in 1946 and 1947 is 450-12, which places the car in a small numeric bias-ply size on a 12-inch rim. The currently available products in that size are BFGoodrich Silvertown Classic Bias Ply tires offered in blackwall and narrow whitewall form.
A restorer who wants to match the car as closely as possible should treat the size as the first requirement and then verify appearance details against period photos, factory literature, or marque references. Sidewall treatment can influence the final look of the car even when the fitment and construction remain the same.
Correct tire fitment can absolutely affect how a Crosley 4 Cyl. is judged and how convincing the finished restoration appears. The right overall size, proper 12-inch rim fitment, bias-ply construction, and an era-appropriate sidewall style all contribute to whether the car looks settled and proportioned the way enthusiasts expect.
For a show-oriented restoration, tire choice is more than a maintenance item because judges and knowledgeable marque enthusiasts often notice stance and sidewall treatment immediately. A Crosley 4 Cyl. restored with the proper size and a carefully chosen visual style generally presents more accurately than one fitted with a convenient but non-period substitute.
Crosley 4 Cyl. tires are available here in Blackwall and Narrow Whitewall versions, both in 450-12 bias-ply form. Either can suit a period-style restoration depending on the look being pursued, since sidewall treatment on postwar compact American cars could range from plain functional presentation to a more dressed finish.
The best choice depends on the exact restoration goal rather than on fitment, because both options share the same basic size and rim diameter. Owners aiming for a stricter historical presentation should compare the tire appearance to surviving photos, factory imagery, and club guidance so the sidewall style supports the car's intended character.
Safety & Road Use
New production bias-ply tires in the correct 450-12 size can be appropriate for public-road use on a Crosley 4 Cyl. when they are properly fitted to sound 12-inch wheels and the rest of the vehicle is mechanically roadworthy. Safe use depends on the whole car, not just the tire, especially on a small postwar collector vehicle with modest size and vintage chassis behavior.
A careful owner should think in terms of conservative use, steady speeds, and realistic expectations rather than modern-car capability. Tire condition, tube condition, wheel integrity, steering play, brakes, and alignment should all be checked together before regular road driving becomes part of the car's routine.
Before driving a Crosley 4 Cyl., check tire inflation, visible sidewall and tread condition, valve stems, wheel fasteners, and whether the tires are seated correctly on the rims. Since the listed fitment is a bias-ply 450-12 on a 12-inch wheel, the driver should also be confident that the car is carrying matched tires and serviceable tubes.
That basic inspection should be paired with a broader look at the car's brakes, steering, wheel bearings, and suspension, because a tire can only perform as well as the surrounding hardware allows. On a collector Crosley, a slow and methodical walkaround before each drive is part of responsible use rather than an optional extra.
A Crosley 4 Cyl. fitted with period-style bias-ply tires should be driven at conservative speeds that respect the age and design of the vehicle as a whole. Even with correct new production tires, the car's compact postwar engineering, light weight, and vintage handling characteristics call for measured road use rather than sustained modern-highway pace.
The practical approach is to treat smooth secondary-road driving as the benchmark and to build speed only within the car's mechanical comfort zone. If the Crosley has not been recently sorted, start with short drives, recheck the tires afterward, and let the condition of the entire car determine how far and how fast it should be used.
