Pontiac 28 Tires

Pontiac 28 uses 650-16 across the listed model years 1939, 1940, 1942, and 1948. All available products for Pontiac 28 in this group are built around a 16-inch rim diameter, with most passenger-car tires suited to 4.50 to 5.00 inch rim widths and one Excelsior option also covering 4.00 to 4.50 inch rims.

That makes Pontiac 28 simpler than many collector applications because the core size does not change by year in this set. The real decision is whether the car needs a traditional passenger-car bias-ply with the sidewall look you want, or a heavier-duty tire in the same size that was designed for truck or utility use.

On a Pontiac 28, 650-16 is a numeric bias-ply size. The 650 portion represents a nominal section width of about 6.50 inches, and the 16 identifies the wheel diameter in inches. In this application, the available tires are bias-ply constructions rather than modern metric radials.

That older size format matters because it points you toward period-correct casing shape and handling characteristics. If the goal is authentic stance and appearance, stay with a true 650-16 bias-ply. It is also wise to inspect the wheel width before final selection, since some products are matched to slightly different rim-width ranges within the same nominal size.

Pontiac 28 uses a 16-inch rim diameter throughout the listed years in this group. Every 650-16 product here is built for a 16-inch wheel, and most of the passenger-car tires are intended for rims in the 4.50 to 5.00 inch width range, with one listing extending down to 4.00 inches.

Even with only one rim diameter in play, it is still worth physically checking the wheels on the car. Collector cars are often restored over decades, and replacement wheels do not always match original specifications. A quick confirmation of rim diameter and width helps narrow the field between the available bias-ply passenger tires and the heavier-duty alternatives.

Pontiac 28 is served primarily by bias-ply tires in the 650-16 size, and a tube is generally required with that style of vintage fitment. One heavier-duty 650-16 listing is specifically identified as tubeless, but the broader selection for Pontiac 28 is built around traditional bias-ply construction.

That means tube choice should be part of the tire decision, not an afterthought. If the car retains original-style wheels, tube-and-flap requirements should be reviewed at the same time as the tire itself. Matching the tube arrangement to the wheel design is especially important on low-use collector cars where age, storage, and long service intervals can hide problems.

A 1939 Pontiac 28 in this group uses 650-16. Since the listed years all share that same size, confirmation is less about sorting through alternate diameters and more about making sure the car still has 16-inch wheels and choosing the product style that matches how the car will be used.

Start with the wheel stamping or a direct measurement, then compare the tire to the car's restoration goals. A blackwall or wide whitewall passenger tire will suit most stock restorations, while the military and truck-type patterns belong only on special-purpose builds or vehicles that genuinely need that tougher tread and casing style.

Pontiac 28 tires are available in both blackwall and wide whitewall sidewall styles within the 650-16 size. The available whitewall choices include several different whitewall widths, while blackwall options span both passenger-car bias-ply tires and heavier-duty truck-oriented products.

That gives a restorer room to match the finished look of the car rather than settling for a one-style-fits-all replacement. A blackwall presentation generally suits a more understated factory appearance, while a wide whitewall can shift the visual character toward a more formal or later-restored look. Check period photos of the specific car before making the final call.

Pontiac 28 tires in 650-16 are offered under BFGoodrich, Coker Classic, Firestone, Garfield, Excelsior, Lester, Goodyear, STA, and Tornel lines. Those brands cover both passenger-car bias-ply products and heavier-duty military or truck-style tires in the same nominal size.

Brand choice on a Pontiac 28 usually comes down to restoration preference, tread style, and sidewall appearance rather than fitment differences alone. If authenticity matters, compare the brand and series to period photographs, judging standards, or marque-club guidance. If road use matters more, focus on selecting the casing style that matches the car's weight and intended driving conditions.

Pontiac 28 is offered in several series families within 650-16, including Silvertown Classic Bias Ply, Coker Classic Bias Ply, Firestone Classic Bias Ply, Garfield Classic Bias Ply, Lester Classic Bias Ply, Deluxe All-Weather, Excelsior Bias Ply, Transport, STA Classic Military, Super Traxion, Transport Highway, Tornel Classic Truck, and Firestone Classic Truck. Some are traditional passenger-car bias-ply lines, while others are truck, highway, military, or traction-oriented casings.

The practical difference is use case. A classic passenger-car series is the natural choice for stock Pontiac 28 appearance and ride character, while Transport, Military, Truck, and Traxion types are more specialized and visually different. Matching the series to the car's purpose will usually matter more than simply matching the nominal 650-16 size.

A Pontiac 28 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and wide temperature swings. Keep the tires properly inflated for the chosen casing, avoid long-term contact with petroleum products, and move the car occasionally so one section of the tread is not carrying the load for months at a time.

Collector-car storage habits have a direct effect on sidewall life and ride quality, especially with bias-ply tires. If the Pontiac 28 will sit for a season, many owners reduce stress by using jack stands correctly or by rolling the car periodically. The goal is to prevent flat spotting, sidewall strain, and age-related cracking from appearing before tread wear is even relevant.

Tires on a Pontiac 28 should be inspected before each drive and more thoroughly at regular intervals even if the car sees little mileage. Look for sidewall cracking, tread separation, punctures, irregular wear, valve-stem issues, and any sign that the tire has begun to distort from age or storage.

Low annual mileage can fool owners into thinking the tires are still fresh when time, not distance, is the real aging factor. A close inspection is especially important on a bias-ply collector tire because handling changes, tube problems, and casing fatigue can develop long before the tread looks worn. A seasonal inspection by a vintage-tire specialist is good practice.

Pontiac 28 tires should be replaced when they show age cracking, hardening, bulges, separations, repeated air loss, or any structural change, even if the tread still looks deep. Collector tires often age out before they wear out, and that is particularly true for vehicles that spend much of their lives parked, trailered, or displayed.

The safest approach is to treat appearance as only one part of the evaluation. A tire that looks usable can still have age-related weakness in the casing or tube area. If the Pontiac 28 has been sitting for years, a full assessment of the tires, tubes, and wheels should come before regular driving resumes.

Pontiac 28 is represented here by the 650-16 size and by period-style bias-ply tire families rather than a single original-equipment brand callout. The available lines include several classic passenger-car series in blackwall and wide whitewall form, which is consistent with the kind of tire presentation restorers usually seek for late 1930s and 1940s American cars.

If originality matters down to brand, tread pattern, or sidewall width, the next step is to compare the car against factory literature, period photos, and Pontiac club references. That research helps determine whether the goal is a strict factory-style restoration or a period-accessory look that still feels at home on a Pontiac 28.

Correct tire fitment can absolutely affect how a Pontiac 28 is judged and how convincingly it presents as a restoration. Size, sidewall treatment, brand family, and tread style all contribute to whether the car looks authentically finished or visibly updated in ways that stand out to knowledgeable judges and marque enthusiasts.

That does not mean every Pontiac 28 needs the same presentation. A touring car may reasonably prioritize drivability and a durable period-style casing, while a concours restoration may need closer attention to sidewall width and brand appearance. Marque clubs and event judging manuals are the best references when points or resale value are part of the equation.

Pontiac 28 restoration tires are available in both blackwall and wide whitewall form in the correct 650-16 size. Either can look period-appropriate depending on the exact year, trim presentation, and the visual character the restorer is trying to recreate, since late prewar and postwar American cars can present differently.

The best choice is the one that matches the car's original appearance rather than modern taste. A blackwall usually gives Pontiac 28 a more restrained factory look, while a wide whitewall creates a dressier presentation. Original photographs, surviving unrestored examples, and Pontiac reference materials are the strongest guides when authenticity is the priority.

A correctly selected and properly maintained 650-16 tire can be suitable for public-road use on a Pontiac 28, provided the tire matches the wheel, the car is mechanically sound, and the intended use fits the casing type. Passenger-car bias-ply tires are the natural match for normal vintage driving, while truck or military patterns should be chosen only when their tread and load style are truly appropriate.

Road safety on a Pontiac 28 depends on the whole system, not the size alone. Brake condition, steering wear, wheel integrity, alignment, inflation, and tube condition all matter. Before regular use, make sure the car has been inspected as a complete vintage vehicle rather than assuming a fresh-looking tire solves every roadworthiness issue.

Before driving a Pontiac 28, check tire inflation, visible sidewall condition, tread condition, valve stems, wheel fasteners, and any sign of rubbing or uneven wear. Because Pontiac 28 uses vintage-style 650-16 tires, it is also wise to confirm that the wheel itself is sound and that any tube-equipped assemblies are holding pressure properly.

Those checks should happen alongside a broader pre-drive inspection of brakes, steering, suspension, and wheel bearings. A collector car that has been sitting can look ready while still hiding age-related problems. A short local test at modest speed after service work is a better first outing than immediately taking the Pontiac 28 onto faster roads.

Appropriate speed for a Pontiac 28 on period-style 650-16 bias-ply tires should be conservative and matched to the age of the car, the condition of the tires, and the overall state of the chassis. Even when the tire is new, a bias-ply collector tire is intended to preserve vintage driving character rather than to behave like a modern high-speed radial.

In practice, that means driving within the comfort zone of the car and avoiding sustained high-speed operation unless the entire vehicle has been thoroughly evaluated for it. Smooth inputs, moderate cruising, and extra following distance suit Pontiac 28 far better than aggressive lane changes or modern traffic pace pushed beyond the car's original character.
