1952 Plymouth P23 Tires

The 1952 Plymouth P23 uses a 670-15 tire size. This is a vintage numeric bias-ply size mounted on a 15-inch rim, and it is the primary fitment for the covered P23 applications.

That means the first step is choosing the right version of 670-15 rather than sorting through several factory sizes. From there, the real decisions are sidewall style, brand, tire series, and whether the car should stay with bias-ply construction or be compared against a radial equivalent after checking wheel width and overall clearance.

The 1952 Plymouth P23 uses a 15-inch rim with its primary 670-15 tire size. The tire size itself confirms the wheel diameter, and the available products for this fitment are built around that 15-inch wheel.

Rim diameter is only part of the picture on an older Plymouth. Wheel width also matters, especially if the car has replacement wheels, and that becomes even more important when comparing among bias-ply products or considering a radial equivalent. A quick wheel check before ordering can prevent clearance or seating issues later.

Yes. The covered 1952 Plymouth P23 Deluxe and 1952 Plymouth P23 Special both use the same 670-15 bias-ply tire size. There is no primary size split between those two sub-models here.

That keeps fitment straightforward, but it does not make every tire choice identical in practice. Owners still need to decide how they want the car to look, whether a blackwall, narrow whitewall, or wide whitewall suits the build, and whether the current wheels remain correct for the tire being considered.

On the 1952 Plymouth P23, 670-15 is the primary bias-ply tire size. That construction matches the traditional sizing and appearance associated with early 1950s American passenger cars.

Staying with bias-ply keeps the period-style look intact and lets the owner choose among several vintage-style sidewall treatments. If a different driving feel is the goal, radial equivalents exist, but they should be treated as alternatives rather than automatic substitutes and checked against the car's wheels, dimensions, and clearance before changing construction.

Radial equivalents for 670-15 include 195R15 as an 80-series metric radial, P205/75R15 as a 75-series P-metric radial, P215/70R15 as a 70-series P-metric radial, and 670R15 as a bias-look radial. Each one represents a different sizing convention or visual approach.

Those options give a 1952 Plymouth P23 owner several ways to compare a radial alternative without abandoning the 15-inch wheel diameter. The recommended rim-width range for the equivalents is 5 to 7 inches, so wheel width, tire dimensions, and fender and steering clearance all deserve a careful check before choosing one.

Start by confirming the wheel diameter and wheel width on the car, then compare the radial-equivalent size being considered for the 1952 Plymouth P23. The available equivalents for 670-15 share the 15-inch rim diameter, but they still need to be evaluated as alternatives rather than assumed replacements.

A careful conversion also includes looking at clearance at the fenders, steering components, and suspension through the full range of movement. The condition of the wheels matters as much as the tire size, especially on a collector car that may have older rims or later modifications. That check helps avoid surprises after installation.

The main factors are correct 670-15 sizing, bias-ply construction, wheel compatibility, and the appearance you want for the car. For a 1952 Plymouth P23, the available tires range from plain blackwall designs to narrow and wide whitewall versions across several classic series.

That means the right choice often depends on how the Plymouth is used and presented. A restoration-minded car may call for one visual style, while a driver may lean toward a different look or construction approach. It also helps to compare rim-width requirements and load figures where they are given rather than choosing by sidewall style alone.

The 1952 Plymouth P23 has 670-15 tire options in blackwall, narrow whitewall, and wide whitewall styles. Those choices create a noticeable difference in the car's visual character even though the primary tire size remains the same.

A blackwall usually gives the car a more restrained, workmanlike presentation, while whitewalls bring a stronger early-1950s flavor. Because several whitewall widths are offered, the best choice depends on how formal or understated the finished car should look. That decision is often just as important as the brand when the size itself is already settled.

Available 670-15 tires for the 1952 Plymouth P23 include options from Firestone, BFGoodrich, Goodyear, US Royal, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA. Those brands appear across several bias-ply series and sidewall styles.

Brand choice is best treated as one part of a larger fitment decision. Once the correct size is confirmed, compare sidewall presentation, rim-width suitability, load figures where shown, and the overall style of the tire series. That approach helps narrow the field without assuming that every tire in the size serves the same purpose.

A period-style 1952 Plymouth P23 starts with the correct primary size, 670-15, in bias-ply construction. From there, the look can be tailored with blackwall, narrow whitewall, or wide whitewall versions depending on how formal, understated, or distinctly early-1950s the finished car should appear.

For many restorers, the question is less about size than presentation. Different brands and series can deliver the same fitment with a different visual effect, especially in whitewall width. If exact originality matters beyond a general period-style result, compare the tire choice against marque references and vehicle-specific historical material before deciding.

Tire construction has a real effect on how a restored 1952 Plymouth P23 looks. A bias-ply 670-15 maintains the traditional vintage sizing language and visual character associated with the car's era, while a radial alternative can change the presentation even when the wheel diameter stays the same.

That is why many restoration-oriented owners begin with the original-style bias-ply fitment and then choose the sidewall treatment that best suits the project. A bias-look radial can also be worth considering for a more traditional appearance, but it should still be judged carefully against the wheels and overall look of the completed car.

Yes. Even though the 1952 Plymouth P23 has a straightforward 670-15 fitment, later changes can affect whether a tire choice still suits the car. Replacement wheels, altered wheel widths, suspension work, or body changes can all influence real-world tire clearance and compatibility.

That matters most when the Plymouth no longer wears its original-style wheel setup or when a radial alternative is being considered. A quick check of wheel diameter, wheel width, and clearance at full steering lock can prevent problems that would not be obvious from the size code alone. Older cars often deserve that extra verification.

Before road use, inspect the wheel condition, verify the tire is seated properly, and confirm that the 670-15 tire has adequate clearance around the fenders, suspension, and steering components. It is also smart to check inflation, lug hardware, and whether all four tires match the intended setup.

Collector cars often sit for long periods, so the inspection should go beyond the tires alone. Brake condition, steering play, wheel-bearing health, and suspension wear can all affect how the car feels once fresh tires are installed. A short test drive followed by a second visual check is a sensible final step.

670-15 tires on a collector 1952 Plymouth P23 should be kept properly inflated, inspected regularly for cracking, bulges, cuts, uneven wear, and air loss, and stored away from prolonged heat, sunlight, and ozone sources. Those habits matter whether the car is driven often or only occasionally.

Low annual mileage does not eliminate tire aging, especially on a car that spends long periods parked. It helps to look over the sidewalls and tread before each outing and after longer storage. Keeping the wheels clean and the car on a sound suspension setup also supports longer tire life and more predictable road manners.
