1949 Plymouth Wagon Tires

The 1949 Plymouth Wagon uses two primary tire sizes: 670-15 and 710-15. Both are vintage numeric bias-ply sizes built for 15-inch rims, and both apply to the Wagon Base. The difference between them centers on section width, with 710-15 being the larger of the two primary fitments.

Choosing between them starts with the wheel already on the vehicle and the wagon’s present setup rather than appearance alone. A surviving original-style wheel, a replacement wheel, or an older restoration may point you toward one size over the other, so wheel width and clearance should be confirmed before selecting a tire.

The primary tire sizes for a 1949 Plymouth Wagon, 670-15 and 710-15, are both designed for 15-inch rims. That means the wheel diameter is consistent even though the wagon has more than one period tire size available. The rim diameter itself is not the part that changes between these two fitments.

Wheel width still matters, especially when comparing the smaller and larger primary sizes or when considering a radial equivalent. A wagon that has had wheels changed over the years should be measured rather than assumed, because diameter alone does not answer whether the rim and tire combination suits the vehicle’s current setup.

The 1949 Plymouth Wagon Base shares the same overall fitment pattern as the model coverage here, using 670-15 and 710-15 bias-ply tires. There is not a separate sub-model-only size to sort through. The main fitment question is which of those two 15-inch sizes belongs on the particular wagon being serviced.

That makes the Base model fairly simple from a cataloging standpoint, but the actual vehicle should still be checked carefully. Older wagons often pass through several owners, and wheel replacements, restoration choices, or long-ago tire substitutions can affect what size makes the most sense to keep on the vehicle today.

On the 1949 Plymouth Wagon, 670-15 is a primary bias-ply tire size. That original-style construction is part of why the size appeals to restoration-oriented owners who want a traditional stance and period presentation. It is not a radial size by itself, even though modern radial equivalents are available for buyers considering an alternative.

Keeping a bias-ply tire preserves the original-style sizing format and the classic sidewall choices available in that size. Moving to a radial equivalent changes the construction, so wheel width, overall dimensions, and clearance should be reviewed before making that change, especially on a collector vehicle that may not still have its original wheel setup.

For 670-15, radial equivalents include 195R15, P205/75R15, P215/70R15, and the bias-look radial 670R15. For 710-15, the radial equivalents are 205R15, P215/75R15, P225/70R15, and the bias-look radial 710R15. Those choices cover an 80-series metric radial, a 75-series P-metric radial, a lower-profile 70-series P-metric radial, and a bias-look radial option for each primary size.

Each equivalent should be treated as an alternative rather than an automatic substitute. The 670-15 group is associated with a 5-7 inch rim-width range, while the 710-15 group is associated with 6-8 inches, and the final choice should still account for wheel compatibility, vehicle dimensions, and clearance at the fenders and steering components.

Start by matching the wagon’s primary bias-ply size to the correct radial-equivalent family, then verify the actual wheel diameter and wheel width on the vehicle. For a 670-15 fitment, the radial-equivalent rim-width range is 5-7 inches, and for a 710-15 fitment it is 6-8 inches. That wheel check comes before any appearance or brand decision.

A conversion also deserves a close look at overall vehicle condition and available space around the tires. Steering clearance, fender clearance, suspension condition, and any non-original wheel or ride-height changes can affect whether an equivalent works well, so the wagon should be inspected as it sits rather than judged only by the original tire designation.

Start with the correct primary size for the wagon’s present wheel setup, then compare the construction and appearance choices available in that size. Both 670-15 and 710-15 are bias-ply fitments on 15-inch rims, but the available products differ by brand, tire series, sidewall treatment, rim-width specification, weight, and in some cases load-capacity figures.

A period-style restoration may point toward a traditional bias-ply with the whitewall or blackwall look you want, while a road-use-focused owner may also compare the radial-equivalent path separately. Once the size is confirmed, narrowing the field by wheel compatibility and visual style usually makes the product decision much easier.

Tires for a 1949 Plymouth Wagon are available in blackwall, narrow whitewall, and wide whitewall styles. Those appearance choices show up across both 670-15 and 710-15 fitments, though the exact combinations vary by brand and tire series. The result is a broad range of visual options while staying within a vintage tire format.

Sidewall choice has a major effect on how the wagon presents, especially on a late-1940s body style where whitewall treatment becomes part of the vehicle’s personality. A blackwall can give a more restrained utility look, while narrow and wide whitewalls push the tire toward a more restoration-oriented or dressier period appearance.

The 1949 Plymouth Wagon has tire options from Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA, depending on size. Those brands appear across several classic bias-ply series, with blackwall and whitewall variations available in the primary 670-15 and 710-15 fitments.

Brand choice is best used as one part of the decision rather than the whole decision. Once the correct size is confirmed, compare the series, sidewall treatment, wheel-width suitability, and any load-capacity information that matters for how the wagon will be used, whether that means show presentation, occasional driving, or utility-minded touring.

A period-style 1949 Plymouth Wagon usually starts with one of its primary bias-ply sizes, 670-15 or 710-15, on a 15-inch rim. That keeps the sizing format and construction in line with the wagon’s late-1940s character. From there, the strongest visual differences come from brand-specific classic series and the choice between blackwall, narrow whitewall, and wide whitewall sidewalls.

The right pick depends on whether the wagon is being preserved as a practical postwar hauler, a dressier restoration, or a road car with traditional looks. When exact originality matters beyond a period-style appearance, the final choice should be checked against marque references, restoration photos, or other vehicle-specific historical documentation.

Construction changes more than driving feel on a restored 1949 Plymouth Wagon; it also changes the tire’s visual character. A bias-ply tire keeps the original-style numeric sizing format and the traditional presentation associated with late-1940s vehicles. A radial equivalent can alter the look, even when it uses the same rim diameter or a bias-look radial approach.

That matters because the tire is one of the first details seen on a wagon with tall body sides and broad fender openings. Owners who want a restoration-oriented appearance often begin with the primary bias-ply size, while those considering a radial should compare the visual result as carefully as the wheel and clearance requirements.

Yes. Modifications can change how either 670-15 or 710-15 works on a 1949 Plymouth Wagon, even though both are proper primary sizes for the model. Aftermarket wheels, altered wheel width, ride-height changes, brake conversions, or body and suspension work can all affect the space available for the tire and what size makes practical sense.

A wagon that looks stock may still have decades-old changes hidden underneath, so measuring the actual wheel and checking clearance is important before ordering tires. That becomes even more important when evaluating radial equivalents, since construction changes do not erase the need to verify steering travel, fender clearance, and overall compatibility.

Before putting a 1949 Plymouth Wagon back on the road with new tires, inspect the wheels for correct diameter and sound condition, and make sure the tire size matches the wheel and the wagon’s setup. The suspension, steering components, and alignment should also be checked so the new tires are not being asked to compensate for worn mechanical parts.

A collector wagon deserves the same close look after installation. Confirm inflation, watch for any signs of rubbing at full steering lock, and recheck the tires after the first drives for air loss or unusual wear. Catching those issues early helps protect both the tires and the road manners of an older vehicle.

Collector-car tire care starts with regular pressure checks, visual inspections, and clean storage conditions. On a 1949 Plymouth Wagon, 670-15 and 710-15 tires should be examined for cracking, bulges, cuts, flat spotting, and uneven tread wear, especially if the wagon sees only occasional use. Long periods of sitting can hide problems until the car is driven again.

Storage habits matter almost as much as mileage on a vehicle from this era. Keeping the wagon away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition, and a quick walk-around before every drive is worthwhile. Any sign of persistent air loss or structural damage deserves professional inspection before road use.
