The 1949 Pontiac reflects the first full postwar wave of American car design, with broader bodies, integrated fenders, and the substantial road presence buyers expected at the end of the 1940s. For collectors and restorers, tire choice on a car from this period has a major effect on stance, appearance, and the way the car presents itself at a glance. This Pontiac uses a 7.10-15/6 bias-ply tire on a 15-inch rim, keeping the fitment squarely in traditional postwar territory. The key decision is usually staying with the proper period-style construction and profile. That makes wheel condition, overall appearance goals, and careful road-use inspection especially important.
Which Tire Size Is Right for The 1949 Pontiac
The 1949 Pontiac uses one primary tire size: 7.10-15/6 in bias-ply construction on a 15-inch rim. The covered Wagon sub-model uses that same fitment, so the main decision is not choosing between multiple factory-type sizes, but selecting the right period-style tire and confirming the wheel and vehicle setup are still consistent with the original fitment pattern.
The 7.10-15/6 size uses a vintage numeric bias-ply format, where 7.10 refers to the tire's nominal section width in inches and 15 identifies the rim diameter. That makes it a traditional postwar American passenger-car size, well suited to the 1949 Pontiac's original-era tire construction and visual proportion. On a vehicle like this, the tire's shape and sidewall presence are part of the car's overall character, not just a basic wear item. Choosing this size keeps the selection centered on authentic-looking fitment, while still making it important to verify the actual wheel and chassis setup before installation.
Sub-model fitment is straightforward for the covered 1949 Pontiac lineup. The Wagon uses the same primary tire size, so the main focus remains choosing the right 7.10-15/6 bias-ply tire and confirming the wheel setup is still correct for the vehicle.

1949 Pontiac Wagon
The 1949 Pontiac Wagon uses the same 7.10-15/6 bias-ply fitment as the core application. That keeps tire selection focused on maintaining the correct vintage sizing and construction, while checking that the wagon still has the proper 15-inch wheels and sufficient clearance for a period-style replacement.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Common questions for the 1949 Pontiac usually center on the 7.10-15/6 tire size, 15-inch rim fitment, period-style bias-ply selection, restoration appearance, and the inspection steps worth taking before putting a postwar collector car back on the road.
Tire Size & Fitment
What tire size fits a 1949 Pontiac?
The 1949 Pontiac uses a 7.10-15/6 tire size in bias-ply construction. That is the primary fitment for this application and it matches a 15-inch rim, keeping the car in the traditional postwar numeric sizing system used on many American vehicles of the period.
Because this Pontiac uses a single primary size, the real task is confirming that the car still has the correct wheel diameter and a stock-style overall setup. Older vehicles are often changed over time, so it is worth checking the wheels already on the car before choosing a replacement tire.
What size rim does a 1949 Pontiac use?
The 1949 Pontiac uses a 15-inch rim with its 7.10-15/6 tire size. That rim diameter is an important part of the fitment, since the tire size is built around a 15-inch wheel and should be matched accordingly.
Rim diameter should be confirmed directly at the wheel, especially on a collector car that may have been altered decades ago. Even when the tire size appears correct, a different wheel diameter or a non-stock wheel setup can change what tire can be mounted safely and how the car sits.
Does the 1949 Pontiac Wagon use the same tire size?
Yes. The 1949 Pontiac Wagon uses the same 7.10-15/6 bias-ply tire size as the covered core fitment. That keeps sub-model selection simple, since there is no second primary size to sort through for the Wagon application.
Even with shared fitment, it still helps to inspect the actual wheels on the vehicle before replacing tires. A wagon that has seen long-term use, restoration work, or aftermarket wheel changes may no longer match its original setup, so wheel diameter and general clearance should still be checked.
Choosing the Right Tire
What should I consider when choosing a 7.10-15/6 tire for a 1949 Pontiac?
Start with the correct size and construction. A 1949 Pontiac uses a 7.10-15/6 bias-ply tire, so the first priority is staying with that vintage fitment pattern rather than treating it like a modern metric application with interchangeable sizing.
After size is settled, the choice becomes about the kind of presentation and use the car will have. A restoration-oriented car may call for a traditional look, while a regularly driven collector car still needs close attention to wheel condition, tire age, load suitability, and overall chassis clearance.
How do I choose between the available 7.10-15/6 tires for a 1949 Pontiac?
Selection within 7.10-15/6 should focus on matching the tire to the car's intended role. On a 1949 Pontiac, that usually means choosing a bias-ply tire that preserves the period look and the visual proportions expected from a full-size postwar American car.
It helps to think about whether the car is being restored for show, preserved as an original-style survivor, or prepared for regular road use at collector-car speeds. Those goals affect how much emphasis to place on appearance, tire freshness, wheel inspection, and overall consistency with the vehicle's existing setup.
What rim-fitment details matter when choosing tires for a 1949 Pontiac?
The key rim-fitment detail is the 15-inch wheel diameter used with the 7.10-15/6 tire size. A tire can only perform as intended when it is mounted on the proper wheel diameter, and that matters especially on a vehicle from 1949 that uses a traditional bias-ply format.
Wheel condition matters just as much as wheel size on an older collector car. Rust, damage, prior repairs, or mismatched replacement wheels can affect how the tire mounts and how the car tracks on the road, so the wheels should be inspected carefully before a fresh set of tires goes on.
Restoration & Appearance
Which tire should I choose for a period-style 1949 Pontiac?
A period-style 1949 Pontiac should begin with the proper 7.10-15/6 bias-ply size. That keeps the car aligned with the proportions and construction style expected of a late-1940s American Pontiac, which is important for preserving the vehicle's visual character during restoration or sympathetic preservation.
Tire choice affects more than appearance alone, but on a postwar restoration the look of the sidewall and the overall shape of the tire have a strong influence on stance. If exact originality matters, marque references and vehicle-specific historical material are worth checking before making the final decision.
Does correct tire fitment matter for a 1949 Pontiac restoration?
Yes, correct tire fitment matters a great deal on a 1949 Pontiac restoration. The right size and construction help maintain the car's intended proportions, keep the wheel openings visually balanced, and support the kind of traditional presentation that makes a late-1940s American car look right.
A mismatched tire can change the car's stance even if it mounts to the wheel, which is why restorers usually begin with the proper 7.10-15/6 bias-ply fitment. It is also wise to inspect wheel condition, ride height, and any past modifications before assuming the car still matches its original setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1949 Pontiac?
Yes. Modifications can affect tire fitment on a 1949 Pontiac even when the correct tire size is known. Changes such as aftermarket wheels, altered suspension height, brake updates, or body repairs can influence clearance and change how a 7.10-15/6 bias-ply tire sits in the wheel opening.
A collector car should be checked as it exists today rather than assumed to be completely stock. Measuring the installed wheel diameter, inspecting wheel width and condition, and looking at fender and steering clearance can prevent ordering a traditional-size tire for a car that no longer has a traditional setup.
What should I inspect before driving a 1949 Pontiac on new tires?
Before road use, inspect the wheels, lug hardware, valve stems, and general chassis condition along with the new tires themselves. On a 1949 Pontiac, it also makes sense to check for rubbing at full steering travel and confirm that the wheels are the correct 15-inch diameter for the 7.10-15/6 fitment.
Collector cars often spend long periods parked, so fresh tires should be part of a broader safety review. Look over the suspension, wheel bearings, brakes, and alignment-related wear patterns, then confirm tire pressure regularly so the car is not being judged by old chassis issues blamed on new tires.
How should 7.10-15/6 tires on a collector 1949 Pontiac be maintained?
7.10-15/6 tires on a collector 1949 Pontiac should be kept properly inflated, inspected often for cracking or impact damage, and protected from long exposure to sun, heat, moisture, and ozone sources during storage. Regular visual checks matter because collector cars may age their tires long before they wear them out.
Driving the car occasionally and checking for vibration, air loss, or uneven wear can help catch problems early. It also helps to inspect the spare if one is carried, since many older Pontiacs still retain an aged backup tire that looks usable but may no longer be suitable for road service.
