1947 Pontiac Tire Fitment Guide

1947 Pontiac vehicles use two tire sizes, and they are model-specific rather than shared across the full lineup. The Streamliner uses 650-16, while the Torpedo uses 600-16. Both are bias-ply sizes and both mount on 16-inch rims. Where rim-width guidance is available, 650-16 fits 4.50 to 5.00 inch rims and 600-16 fits 4.00 to 4.50 inch rims.

That makes model identification the first step before choosing a tire for a 1947 Pontiac. A Streamliner owner should begin with 650-16 options, while a Torpedo owner should stay with 600-16. Once the model and size are confirmed, the next decision is usually visual presentation, such as blackwall versus wide whitewall, rather than changing to a different basic fitment.

On a 1947 Pontiac, 650-16 is a traditional numeric bias-ply size. The 650 designates the tire's nominal section width in period numeric sizing, and the 16 identifies the wheel diameter in inches. For 1947 Pontiac applications, that size belongs to the Streamliner. Available examples include both blackwall and wide whitewall bias-ply tires.

A buyer reading 650-16 should think in terms of correct vintage sizing rather than modern metric dimensions. The key practical checks are that the car is in fact a 1947 Pontiac Streamliner and that the wheel falls within the published rim-width range used by the tire being considered. After that, the choice usually comes down to appearance and restoration goals.

No, 1947 Pontiac models do not all use the same tire size. The Streamliner uses 650-16, while the Torpedo uses 600-16. Both sizes are 16-inch bias-ply fitments, but they are not interchangeable as a year-make-wide standard simply because they share the same rim diameter.

That distinction matters because many postwar Pontiacs can look broadly similar at a glance, especially after decades of ownership changes, restoration work, or mixed parts. If the body style is uncertain, checking the actual car's model identification and wheel setup before choosing tires is the right move. Confirming the model first prevents ordering a wider or narrower fitment than the car was meant to use.

1947 Pontiac tires are available in both blackwall and wide whitewall styles across the two correct sizes. The 650-16 Streamliner fitment includes blackwall and wide whitewall offerings, and the 600-16 Torpedo fitment does as well. That gives owners a choice between a plainer service look and the more formal whitewall appearance that suits many postwar American restorations.

For a 1947 Pontiac built as a factory-style restoration or show car, whitewall selection often has a strong effect on the car's visual stance and period impression. Blackwalls can be a sensible choice for a more understated presentation or for owners recreating a less dressy look. The right answer depends less on mechanical fitment than on how original and how era-specific you want the finished car to appear.

Several brands cover 1947 Pontiac fitments. In 650-16 for the Streamliner, available brands include BFGoodrich, Coker Classic, Firestone, and Garfield. In 600-16 for the Torpedo, available brands include BFGoodrich, Coker Classic, Avon, and Firestone. All of the listed options are bias-ply tires for these Pontiac applications.

Brand choice on a 1947 Pontiac usually comes down to the combination of sidewall styling, series identity, and the details published for the individual tire. Some owners favor a familiar American-brand look for a domestic postwar car, while others simply focus on whether the tire delivers the right size and sidewall presentation. Once the proper model-specific size is confirmed, comparing brands becomes much more straightforward.

For 1947 Pontiac Torpedo fitment in 600-16, both BFGoodrich and Firestone offer bias-ply wide whitewall tires. Each carries a maximum load figure of 1400 pounds at 32 psi and fits 4.00 to 4.50 inch rims. The main visible difference between the examples listed is whitewall width: BFGoodrich uses a 3.50-inch whitewall, while Firestone uses a 3.25-inch whitewall.

That means the choice between those two 1947 Pontiac 600-16 options is largely aesthetic when the car is being kept in proper period form. A slightly wider whitewall creates a more prominent postwar dressy look, while a slightly narrower whitewall gives a subtler appearance. Since the core fitment and load specification are closely aligned, owners can focus on the visual balance they want against the car's trim and body color.

1947 Pontiac tire rim width depends on the model-specific size. The 650-16 tires used on the Streamliner fit 4.50 to 5.00 inch rims where published specifications are available. The 600-16 tires used on the Torpedo fit 4.00 to 4.50 inch rims on products that publish rim-width guidance. Both sizes mount on 16-inch wheels.

Rim width matters because a tire can share the correct wheel diameter yet still be mismatched to the wheel if the width falls outside the intended range. Before fitting a new set on a 1947 Pontiac, it is wise to verify the actual wheel width on the car rather than relying only on appearance. That extra step is especially helpful on cars that may have had wheel changes during earlier restoration work.

1947 Pontiac tires in these original-style sizes are bias-ply products, but tube status should be confirmed on the exact tire being considered rather than assumed from size alone. The available fitments are offered in vintage-style constructions and sidewall styles that may be used on wheels originally designed around tube-type practice. The safest approach is to check the specific sidewall marking and wheel condition before final installation.

A 1947 Pontiac owner should also consider the condition of the wheel itself, especially the bead seat and valve-stem area on older steel wheels. If tubes are required or recommended for the exact tire-wheel combination, the tube, flap if applicable, and valve hardware should all be chosen as part of the setup rather than as afterthoughts. That is particularly important on collector cars that sit for long periods between drives.

Original 1947 Pontiac wheels can share the same 16-inch rim diameter in principle because both correct tire sizes, 600-16 and 650-16, mount on 16-inch rims. That does not make the two sizes interchangeable across all 1947 Pontiac models, because the published rim-width ranges differ between them. The Torpedo's 600-16 fitment uses a narrower rim-width range than the Streamliner's 650-16 fitment.

The practical takeaway is that wheel diameter alone is not enough when comparing tires for a 1947 Pontiac. A car may have 16-inch wheels and still need the model-correct width range to support the intended tire properly. If the wheels have ever been swapped, measured wheel width should be part of the confirmation process before using one size in place of another.

A stored 1947 Pontiac should be kept out of direct sunlight and away from electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Dry, cool conditions are better than damp floors or hot sheds, and the car should be moved periodically so one part of each tire is not carrying the load continuously. Bias-ply tires are more prone to temporary flat-spotting during long static storage than modern radials.

If a 1947 Pontiac will sit for months, many owners slightly reduce sustained load by using stands placed correctly under the chassis while keeping the suspension supported as appropriate for the storage plan. Tire covers can also help shield the sidewalls from light. The goal is to preserve sidewall flexibility and shape so the car returns to service without avoidable cracking, spotting, or pressure loss.

On a 1947 Pontiac, tire age usually matters more than mileage because many collector cars are driven lightly. A reasonable rule is to evaluate tires closely once they reach the five-to-seven-year range and to treat around ten years as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code and the tire's storage history are often more revealing than the odometer on the car.

That age-based approach is especially important on a 1947 Pontiac because old-looking tires may still appear cosmetically acceptable while the casing and sidewall rubber have hardened over time. A car that attends shows, club tours, or seasonal drives should not rely on appearance alone. If there is any doubt about age, cracking, or prior storage conditions, replacement is usually the wiser course than stretching service life.

Tires on a 1947 Pontiac should be inspected before every drive and again before any longer outing. The key checks are pressure retention, visible cracking, cuts, bulges, unusual tread wear, and signs of impact damage from prior use or storage. On a vintage wheel and tire package, the valve-stem area also deserves attention, especially if the setup uses tube-type components.

Frequent inspection matters because collector cars often spend more time parked than moving, and problems can develop quietly between outings. A 1947 Pontiac that feels fine on a short neighborhood loop can still reveal age-related issues once speed, heat, and distance increase. Making tire inspection part of the same routine as checking fluids and brakes helps catch small issues before they become roadside problems.

A 1947 Pontiac Streamliner would have been fitted in bias-ply construction, not radial, because bias-ply was standard practice for American passenger cars in that period. The model-specific size used here is 650-16, mounted on a 16-inch wheel. Modern replacement choices in that size stay within the same general vintage construction approach while offering blackwall and wide whitewall styling depending on the restoration direction.

For a highly exact 1947 Pontiac Streamliner restoration, size, construction type, and sidewall appearance should all be checked against factory literature, surviving original photos, and marque-club guidance. Sidewall branding and whitewall treatment can vary by market, trim, and owner preference over the car's life. If the goal is judged authenticity, confirming those details before final selection is worth the effort.

Correct tire fitment does matter when showing a 1947 Pontiac, especially in judged classes that reward factory-style presentation. Judges and knowledgeable enthusiasts will notice whether the size matches the correct model, whether the tire uses period-appropriate bias-ply construction, and whether the sidewall treatment suits the era. A Streamliner on 600-16 tires or a Torpedo on 650-16 tires would stand out as a visible mismatch.

The effect is not only technical but visual, because the wrong size or sidewall style can alter the car's stance and the way the wheel opening is filled. Owners building a 1947 Pontiac for concours or marque events should compare their chosen tire against event standards and club expectations before mounting a full set. That extra research helps avoid otherwise strong restorations being marked down over tire presentation.

For 1947 Pontiac Streamliner fitment in 650-16, BFGoodrich and Firestone both offer bias-ply options with the same published maximum load of 1580 pounds at 32 psi and the same 4.50 to 5.00 inch rim-width range. The visible distinction in the examples listed comes down to sidewall treatment, since BFGoodrich appears in a 3.75-inch whitewall version while Firestone is represented in blackwall form.

That makes the decision useful for restoration planning because the two tires can support different visual goals on the same 1947 Pontiac Streamliner fitment. A wide whitewall leans into the dressed-up late-1940s American look, while a blackwall gives a more restrained appearance. If the car is being judged, the right choice should be guided by the exact presentation you are trying to recreate.

1947 Pontiac tires can be suitable for highway use when they are the correct size, properly installed, correctly inflated, and in sound condition. The available fitments for this year are bias-ply tires, and one 600-16 offering carries an H speed rating, which corresponds to a 130 mph ceiling. In ordinary collector-car driving, the tire's published rating is only part of the picture because the car's brakes, steering, suspension, and overall condition matter just as much.

A well-sorted 1947 Pontiac used at sensible speeds is a different situation from sustained modern high-speed travel. Owners should think in terms of the entire car rather than the tire alone, especially on a postwar chassis that was engineered for a very different road environment. Good highway manners start with fresh tires, proper pressure, sound wheels, and realistic expectations about how a 1947 car behaves.

Inflation pressure for a 1947 Pontiac should follow the vehicle's original factory guidance for normal service while staying within the tire maker's published limits for the exact product selected. Among the available examples, 650-16 tires are listed with a maximum load of 1580 pounds at 32 psi, and 600-16 tires appear with maximum load figures of 1400 pounds at 32 psi, with another 600H16 example listed at 1,433 pounds. Those figures are tire ratings, not universal instructions for every driving condition.

The best approach is to start with the factory recommendation for the model and then confirm the selected tire's limits before putting the car into regular use. A 1947 Pontiac used for solo local driving may want a different operating pressure feel than one carrying passengers on a tour, but pressure should never be guessed from appearance alone. Consistency side to side is just as important as the chosen number.

Before a longer drive in a 1947 Pontiac, inspect each tire for cracking, embedded debris, sidewall bulges, uneven wear, and any loss of pressure since the last outing. Check the valve stems, and if the tire setup uses tubes, make sure the entire assembly has been installed and maintained with tube-compatible hardware. The spare should be inspected as carefully as the four road tires, since a long-stored spare often ages out unnoticed.

Tires are only one part of the pre-drive routine on a 1947 Pontiac, but they are the only part touching the road. A longer trip also calls for a broader mechanical check that includes brakes, wheel bearings, steering response, and fluid levels, because an older car asks more of the owner than a modern commuter does. Taking those steps beforehand makes the drive more enjoyable and far less stressful.
