The 1950 Plymouth Wagon came from an era when practical family transportation still carried strong styling cues from the late 1940s, making these wagons especially appealing to restorers who want utility without giving up period character. On a vehicle like this, tire choice affects stance and appearance as much as road manners. The 1950 Plymouth Wagon uses 670-15 and 710-15 bias-ply tires on 15-inch rims, so the first step is confirming which setup is on the car. From there, the choice can move toward blackwall, narrow whitewall, or wide whitewall bias-ply options, or toward modern radial equivalents when a different driving feel is the goal.
Which Tire Size Is Right for The 1950 Plymouth Wagon
The 1950 Plymouth Wagon uses two primary tire sizes, both in bias-ply construction on 15-inch rims. Because the same sub-model can appear with either 670-15 or 710-15, the key step is confirming which tire size is actually on the vehicle now and making sure the wheel width matches the tire being considered. Once size is confirmed, the real choice becomes sidewall style, brand, series, and whether to stay with bias-ply or evaluate a radial equivalent.
A 670-15 is a vintage numeric bias-ply size in which the 6.70 designation refers to the tire's nominal section width in inches, and the 15 identifies the wheel diameter. For a 1950 Plymouth Wagon, this keeps the period-style bias-ply construction that suits a restoration-oriented appearance and traditional fitment. In this size, choices include blackwall, narrow whitewall, and wide whitewall options across brands such as Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA. This size is worth choosing when the wagon's wheels, stance, and appearance goals line up with the narrower 6.70-inch profile family.
A 710-15 is also a vintage numeric bias-ply size, with the 7.10 designation indicating a wider nominal section width than 670-15 while still fitting a 15-inch wheel. On the 1950 Plymouth Wagon, it remains a period-style bias-ply fitment, so the character of the tire stays true to the vehicle's era. Available products include blackwall, narrow whitewall, and wide whitewall designs from brands such as BFGoodrich, Firestone, US Royal, Goodyear, and Universal Vintage Tire. This size deserves a closer look when the wagon already carries the wider wheel and tire setup or when a fuller sidewall presentation is part of the desired finished look.
Tire fitment on the covered 1950 Plymouth Wagon sub-model is straightforward in one sense and still worth checking carefully in another. The Base wagon can use either 670-15 or 710-15, so confirming the actual wheel and tire setup on the vehicle matters before choosing a replacement.

1950 Plymouth Wagon Base
The 1950 Plymouth Wagon Base uses bias-ply tires and may be equipped with either 670-15 or 710-15 on 15-inch rims. That makes wheel confirmation especially important, after which the choice usually comes down to period-style sidewall appearance, brand and series preference, or whether to compare a radial equivalent.
Bias-Ply to Radial Tire Conversion for the 1950 Plymouth Wagon
For the original 670-15 size, four radial-equivalent choices are available: 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. For 710-15, the equivalents are 205R15, P215/75R15, P225/70R15, and 710R15 in the same progression. These options vary by sizing convention and profile, with the bias-look radial aimed at a more traditional appearance. Recommended rim width ranges are 5-7 inches for 670-15 and 6-8 inches for 710-15, and wheel compatibility and clearance should be checked before any conversion.

Best 1950 Plymouth Wagon Tires for Sale
Available 1950 Plymouth Wagon tire choices span 670-15 and 710-15 bias-ply sizes from Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, and others, with blackwall, narrow whitewall, and wide whitewall treatments across several classic tire series.
These 1950 Plymouth Wagon tire FAQs focus on choosing between 670-15 and 710-15, understanding vintage bias-ply sizing, comparing radial equivalents, and checking wheel fitment, appearance, and road-use readiness before the wagon goes back into service.
Tire Size & Fitment
What tire size fits a 1950 Plymouth Wagon?
The 1950 Plymouth Wagon uses either 670-15 or 710-15 tires, and both are primary bias-ply fitments on 15-inch rims. That means there is not just one universal size for every wagon still on the road today, even within the same model year and sub-model coverage.
The practical next step is to confirm which size is actually mounted on the vehicle and whether the wheel width matches that tire. A wagon restored years ago, fitted with different wheels, or changed for appearance may not still carry its earlier setup, so checking the tire sidewall and wheel before ordering helps avoid an incorrect choice.
What size rim does a 1950 Plymouth Wagon use?
The 1950 Plymouth Wagon uses a 15-inch rim with both of its primary tire sizes, 670-15 and 710-15. The final number in each vintage numeric size is the rim diameter, so both fitments belong to the same 15-inch wheel diameter family.
Rim diameter is only part of the fitment picture, because wheel width still matters when choosing between 670-15 and 710-15 or when considering a radial equivalent. It is smart to verify both the wheel diameter and the actual wheel width on the vehicle, especially if the wagon has had replacement wheels or a long-ago restoration.
What does 670-15 mean on a 1950 Plymouth Wagon?
On a 1950 Plymouth Wagon, 670-15 is a vintage numeric bias-ply tire size. The 6.70 number refers to the tire's nominal section width in inches, and the 15 refers to the wheel diameter in inches. It is an older sizing system commonly seen on American vehicles from this period.
Understanding that format helps when comparing modern alternatives, because later radial sizes use different naming conventions. A 670-15 should be treated first as a period bias-ply fitment, and any move to a radial equivalent should include a check of wheel width, clearance, and the wagon's current stance rather than assuming modern size labels behave the same way.
Bias-Ply & Radial Options
Is 670-15 a bias-ply or radial tire for the 1950 Plymouth Wagon?
For the 1950 Plymouth Wagon, 670-15 is a primary bias-ply tire size. It belongs to the vintage numeric bias-ply system and is one of the two original-style fitment families used on this model, both mounted on 15-inch rims.
That matters because a bias-ply tire preserves the period-style look and traditional construction that many restorations aim to keep. A radial can still be considered through an equivalent size, but the decision should be made deliberately after checking wheel width, overall fit on the vehicle, and whether the goal is authentic presentation, different road feel, or a blend of both.
What radial tire sizes are equivalent to 670-15 and 710-15?
For 670-15, radial equivalents include 195R15, P205/75R15, P215/70R15, and the bias-look radial 670R15. For 710-15, the equivalent choices are 205R15, P215/75R15, P225/70R15, and the bias-look radial 710R15. These cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial option for each original size.
Those alternatives are useful comparison points, but they should not be treated as automatic replacements. Wheel width, overall dimensions, and available clearance at the fenders and steering should all be reviewed before switching, and the bias-look radial is the option most clearly aimed at buyers who want a more traditional visual presentation than a standard modern radial.
What should I check before converting my 1950 Plymouth Wagon from bias-ply to radial tires?
Start by confirming the wagon's existing primary size, whether that is 670-15 or 710-15, and then compare it to the correct radial-equivalent options for that size. The wheel diameter remains 15 inches, but wheel width still needs to be appropriate for the radial size under consideration.
A conversion also calls for checking real-world clearance at the front suspension, steering sweep, and rear fender area, especially on an older vehicle that may have had wheel or suspension changes over the years. It is also wise to think about the wagon's intended use, since some owners want a period-style bias-ply presentation while others prioritize a radial alternative.
Choosing the Right Tire
What should I consider when choosing a 670-15 or 710-15 tire for a 1950 Plymouth Wagon?
The first consideration is choosing the correct primary size already matched to the wagon's wheels, since both 670-15 and 710-15 are used on this model. After that, compare construction style, sidewall appearance, and whether the tire is aimed more toward restoration presentation or a different road-use approach through a radial equivalent.
Product details also help narrow the decision. Rim-width specifications, load figures where stated, and differences in tire series can all matter, especially on a wagon that may carry passengers or cargo. A buyer who wants the vehicle to look strongly period-style may focus on bias-ply and whitewall treatment, while a different buyer may begin by evaluating the equivalent radial sizes.
What sidewall styles are available for 1950 Plymouth Wagon tires?
Tires for the 1950 Plymouth Wagon are available in blackwall, narrow whitewall, and wide whitewall styles. Those choices appear across both 670-15 and 710-15 fitments, although the exact sidewall treatment varies by brand and tire series within each size.
Sidewall style has a big effect on how the wagon presents, especially on a 1950 body where the tire is a visible part of the overall profile. Blackwall gives a simpler utility look, while whitewall options push the appearance more toward a dressed, restoration-oriented finish. The right choice depends on the look of the vehicle, not just the tire size itself.
What brands offer tires for the 1950 Plymouth Wagon?
The 1950 Plymouth Wagon has tire options from Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA, depending on size and series. Most of the assortment centers on classic-style bias-ply tires in 670-15 and 710-15, with sidewall treatments varying by product line.
Brand choice should be treated as one part of a broader fitment decision rather than the starting point by itself. It helps to first confirm whether the wagon needs 670-15 or 710-15, then compare which brands offer the sidewall style, rim-width compatibility, and overall presentation that suit the vehicle's wheels, restoration direction, and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1950 Plymouth Wagon?
A period-style 1950 Plymouth Wagon usually starts with the correct primary bias-ply size already on the vehicle, either 670-15 or 710-15. From there, the appearance decision often centers on blackwall versus whitewall treatment and on choosing a classic bias-ply series that matches the wagon's overall restoration character.
Because surviving wagons and restored cars do not always wear the same wheel and tire setup, it helps to verify the existing fitment before focusing on appearance details. Buyers seeking strict originality should compare their choice against marque references, photos, or restoration documentation, while others may simply want a convincing period-style look that suits the finished vehicle.
How does tire construction affect the appearance of a restored 1950 Plymouth Wagon?
On a restored 1950 Plymouth Wagon, bias-ply construction usually supports the most traditional visual impression because the tire belongs to the same style family the vehicle originally used. The available 670-15 and 710-15 bias-ply options also give access to blackwall, narrow whitewall, and wide whitewall presentations.
A radial equivalent can change that visual character, even when the rim diameter remains the same. Buyers who want a modern radial but still prefer an older look may want to consider the bias-look radial equivalents, then judge the result against the wagon's wheels, ride height, and restoration goals rather than viewing construction choice as only a mechanical decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1950 Plymouth Wagon?
Yes, modifications can affect tire fitment on a 1950 Plymouth Wagon even when the vehicle still uses a 15-inch wheel. Changes such as aftermarket wheels, different wheel widths, altered ride height, suspension work, or body and fender repairs can all influence whether a 670-15, 710-15, or radial equivalent has adequate space.
That is why it is important to inspect the vehicle as it sits today instead of assuming every wagon matches stock dimensions. A quick check of wheel width, steering clearance, and space at the outer fender and inner suspension points can prevent trouble, especially when moving from one primary size to the other or considering a radial alternative.
What should I inspect before driving a 1950 Plymouth Wagon on new tires?
Before driving a 1950 Plymouth Wagon on new tires, inspect the wheels, valve stems, lug hardware, and basic clearances with the vehicle at rest and with the steering turned through its range. It is also smart to confirm inflation, look for any contact points, and make sure the selected size matches the wheel actually installed.
An older wagon deserves a broader once-over before road use, especially if it has been stored or driven infrequently. Check for steering looseness, suspension wear, brake condition, and any sign that the body or chassis sits unevenly, since those issues can affect how the new tires behave even when the chosen size itself is correct.
How should 670-15 or 710-15 tires on a collector 1950 Plymouth Wagon be maintained?
Collector-car tires in 670-15 or 710-15 size should be maintained with regular pressure checks, routine visual inspection, and attention to how the wagon is stored. Even when tread wear is low, a vehicle that sits for long periods can develop age-related concerns that matter just as much as mileage.
Keep the Plymouth in a cool, dry place away from prolonged sunlight and ozone sources, and inspect the tires for cracking, bulges, cuts, uneven wear, and persistent air loss before each driving season. Short, periodic inspections are valuable on low-use collector vehicles because storage time can hide problems that would be obvious on a regularly driven car.
