Pontiac Torpedo Tires

Pontiac Torpedo uses two listed tire sizes across the 1946 to 1948 span: 600-16 and 650-16. The 600-16 size is used on 1946, 1947, and some 1948 applications, while 650-16 appears on 1948 applications only. Both sizes are built for 16-inch rims, but they differ in nominal section width, with 600 representing a narrower bias-ply fitment and 650 representing a larger one.

That means year alone is enough for 1946 and 1947, but 1948 owners need to verify which of the two listed sizes belongs on their specific Pontiac Torpedo. The best approach is to check the tire already on the car, compare the wheel and clearance, and verify against factory literature or a Pontiac marque specialist if the car has been restored or modified in the past.

A 600-16 size on a Pontiac Torpedo is a numeric bias-ply designation. The 600 portion represents a nominal 6.00-inch section width, written without a decimal point, and the 16 identifies the rim diameter in inches. For Pontiac Torpedo applications, that size appears across 1946, 1947, and 1948, and all listed products in that size are bias-ply designs.

Modern buyers sometimes assume a vintage number string works like a contemporary metric size, but it does not. On a Pontiac Torpedo, 600-16 is part of a period-correct sizing system, so the right choice depends on matching the actual wheel and the intended look of the car, especially if you are deciding between blackwall, wide whitewall, or other era-appropriate sidewall treatments.

A 1948 Pontiac Torpedo has two listed tire sizes because that model year includes both 600-16 and 650-16 applications. The split is not a rim diameter change, since both sizes fit 16-inch wheels, and it is not a construction split, since the available products are all bias-ply. The difference is a fitment variation within the 1948 model range, likely tied to configuration rather than wheel diameter.

That makes the specific car more important than the calendar year alone. If you own a 1948 Pontiac Torpedo, confirm the existing tire size, wheel width, and overall stance before replacing tires, and use original literature, restoration records, or experienced Pontiac references to determine whether the car should wear the 600-16 or the larger 650-16 fitment.

Pontiac Torpedo fitments in both 600-16 and 650-16 are bias-ply numeric sizes, and a tube is required for those applications. That applies across the listed year range from 1946 through 1948, since the available passenger-car style products in both sizes are bias-ply constructions associated with period wheel setups. Tube-type fitment is part of how these vintage sizes were intended to be used.

When replacing tires on a Pontiac Torpedo, tube condition matters as much as the tire itself. A fresh tire mounted with an aged or mismatched tube can create avoidable problems, so owners should treat tube replacement, flap condition if applicable, and careful wheel inspection as part of the overall fitment job rather than as secondary details.

A 1948 Pontiac Torpedo can use either 600-16 or 650-16, while 1946 and 1947 use 600-16. Both 1948 sizes are for 16-inch rims, so the decision is not about wheel diameter but about which fitment belongs to the specific configuration of the car. Checking the current tire size, wheel width, and any surviving factory or restoration paperwork is the most direct way to confirm the correct application.

Cars that have changed hands over decades are often fitted with whatever was available at the time, so the tire on the car may not always settle the question by itself. If the Pontiac Torpedo is being judged, restored, or returned to original appearance, compare the current setup against period references and consult a marque specialist before settling on 600-16 or 650-16.

Pontiac Torpedo tires are available with blackwall, wide whitewall, and double-whitewall sidewall styles, although the full range varies by size. The 600-16 offerings include blackwall, wide whitewall, and double-whitewall choices, while 650-16 includes blackwall and wide whitewall options. Those variations let an owner tune the car toward a more understated postwar look or a dressier period presentation.

For a Pontiac Torpedo restoration, sidewall choice should follow the car's intended use and visual target rather than personal preference alone. A blackwall often suits a simpler or utility-minded presentation, while wide whitewalls align with the upscale postwar appearance many owners want, so compare old photos, showroom literature, or club guidance if originality matters.

Pontiac Torpedo tires are offered by BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, Camac, Garfield, and Tornel. Those brands appear across the two listed sizes, with the broadest selection in 600-16 and a still substantial range in 650-16. The available lines include classic passenger-car bias-ply styles as well as some military or truck-oriented tread families in the same nominal sizes.

For most Pontiac Torpedo passenger-car restorations, the right brand choice is usually less important than selecting the correct size, correct type of construction, and a sidewall style that fits the car's era and character. Owners should also separate appearance-focused passenger tires from truck or military-style patterns unless the car has a very specific historic presentation in mind.

Pontiac Torpedo fitments appear in a wide mix of series, including Silvertown Classic Bias Ply, Coker Classic Bias Ply, Turbospeed Mk4, Firestone Classic Bias Ply, Ford Script, Excelsior Bias Ply, Lester Classic Bias Ply, Tourist Crossply, Traction Mileage, Deluxe All-Weather, Firestone Classic Military, Firestone Military NDT, Military NDT, NATO CJ110, Firestone Classic Truck, Garfield Classic Bias Ply, Transport, STA Classic Military, Super Traxion, Transport Highway, and Tornel Classic Truck. The main distinction is between passenger-car bias-ply lines styled for period road cars and more utilitarian military or truck tread families in the same sizes.

That matters because a Pontiac Torpedo restored as a postwar passenger car usually wants a classic road-going bias-ply tire with the right sidewall appearance, not an NDT, truck, or traction tread. The series name helps separate period-correct visual style from more rugged commercial use, so choose with the finished look and driving purpose of the car in mind.

A Pontiac Torpedo should be stored on a clean, dry surface away from direct sunlight, ozone sources, and wide temperature swings. Bias-ply tires tend to flat-spot more readily than modern radials when they sit for long periods, especially on a heavy postwar car. Keeping the tires properly inflated and the storage area free from solvents, electric motor ozone, and moisture helps preserve both casing shape and sidewall appearance.

If the Pontiac Torpedo will sit for months at a time, move it periodically or take some weight off the tires with proper support under the chassis as part of a planned storage routine. Owners who care about whitewall appearance should also keep the sidewalls clean and avoid harsh dressings that can stain or dry the rubber over time.

Tires on a Pontiac Torpedo should be inspected before each drive and more thoroughly at regular intervals during the season. On a collector car with bias-ply tires, that means checking inflation, tread condition, sidewall cracking, bead area condition, and any signs of tube or valve stem trouble. Because these cars are often driven infrequently, age-related deterioration can matter more than mileage.

A practical routine is to give the Pontiac Torpedo a walk-around before every outing, then perform a closer inspection during seasonal maintenance or whenever the car comes out of storage. If the car feels different on the road, develops a pull, or has been parked on old tires for years, a professional inspection is wise before any longer drive.

Tires on a Pontiac Torpedo should be replaced when age, cracking, casing stiffness, impact damage, uneven wear, or prolonged storage history raises concern, even if tread depth still looks usable. Collector-car tires often age out long before they wear out, and bias-ply construction can hide deterioration until the tire is closely examined. Tread alone is never the full story on a low-mileage vintage car.

Owners should think in terms of condition and service history rather than miles traveled. If a Pontiac Torpedo is still riding on older tires of uncertain age, replacement is usually a safer path than trying to stretch their life, particularly before touring use, and any period-used or long-stored tire deserves a careful specialist evaluation before it remains in service.

Pontiac Torpedo fitment in the 1946 to 1948 span centers on 600-16, with 650-16 also appearing for 1948 applications. The available replacement lines are all bias-ply in period-style formats, which aligns well with the car's postwar design era. Multiple series and sidewall treatments are available today, but the exact original brand and presentation for a specific Pontiac Torpedo depend on the year and individual configuration.

For an owner restoring a Pontiac Torpedo to factory-style appearance, size is the first authenticity decision and sidewall treatment is the second. Original literature, surviving photos, and Pontiac club references remain the best way to narrow whether the car should wear a blackwall or a whitewall presentation and whether the 1948 car belongs with 600-16 or 650-16.

Correct tire fitment can absolutely affect how a Pontiac Torpedo is judged and how convincing the finished restoration looks. Size, sidewall style, and the overall stance created by the tire all influence whether the car presents as properly restored for its period. On a postwar American car, an obviously incorrect tire can stand out even to casual observers, and to judges it can be a meaningful detail.

That is especially important for 1948 Pontiac Torpedo models because there are two listed sizes and the wrong one can change the car's proportions. Owners pursuing show judging or top-tier restoration work should match the tire not only to the year but to the specific configuration of the car, using marque clubs and period references as the final authority.

Pontiac Torpedo tire offerings include blackwall, wide whitewall, and, in 600-16, double-whitewall choices. All are period-style presentations, but they create different visual results on a late-1940s Pontiac. Blackwalls give a more restrained postwar look, while wide whitewalls emphasize the dressier styling that many restorers associate with upscale late-1940s American cars.

The correct choice for a Pontiac Torpedo restoration depends on the exact character you are trying to recreate. If authenticity matters, compare the car against period advertising, family photos, or club guidance rather than choosing by appearance alone, because the sidewall treatment has a strong effect on how accurately the car reads from the curb.

Properly fitted new bias-ply tires in the correct Pontiac Torpedo size can be suitable for public-road use when the rest of the car is equally roadworthy. The listed 600-16 and 650-16 options are period-style bias-ply constructions, so they should be judged as vintage-type tires intended for a vintage-type driving experience rather than as direct equivalents to modern touring radials.

Safe road use depends on the whole car, not just the rubber. Before driving a Pontiac Torpedo in traffic, owners should make sure the wheels, brakes, steering, suspension, alignment, and tubes are in sound condition and should expect the car to feel and respond like a late-1940s automobile, especially in braking distance and lane stability.

Before driving a Pontiac Torpedo, check tire inflation, visible sidewall condition, tread condition, valve stems, and any signs of tube leakage or bead disturbance. Because both listed Pontiac Torpedo sizes are 16-inch bias-ply fitments, the car should also be checked for steering play, brake performance, and wheel condition before regular road use. A tire that looks usable at a glance can still be unsuitable if the casing or tube condition is poor.

A sensible pre-drive routine helps catch problems before they turn into roadside issues. On a Pontiac Torpedo that has been sitting, owners should also watch for flat-spotting, vibration, or wandering on the first miles and stop to recheck the car if anything feels unusual rather than assuming the old-car driving experience is supposed to feel that way.

A Pontiac Torpedo on period-style bias-ply tires should be driven at moderate speeds that respect the car's age, construction, and handling characteristics. Even when the tires are fresh, a late-1940s full-size car on bias-ply tires will not track, steer, or stop like a modern vehicle on modern radials. The right speed is the one that stays well within the limits of the car, the tires, and current road and weather conditions.

In practice, that means treating a Pontiac Torpedo as a vintage touring car rather than a modern highway cruiser. Conservative speed, longer following distance, smooth steering inputs, and extra caution on wet pavement all help the car work with its tire design instead of against it, which is especially important if originality is part of the goal.
