Pontiac 27 Tires

Pontiac 27 uses one tire size across the years covered here: 600-16 for both 1941 and 1942. The products offered in that size are built around a 16-inch rim diameter, and many of the passenger-car options list recommended rim widths in the 4.00 to 4.50-inch range. Every listed Pontiac 27 tire is a bias-ply design, with choices that include blackwall, wide whitewall, double-whitewall, and several military-style tread patterns.

That makes fitment identification simpler than on many collector cars, but it still helps to check the wheel on the car before making a final choice. The most important decision is usually whether the Pontiac 27 is being restored to a period passenger-car appearance or fitted for a more specialized military or utility-style look, since all of those options appear within the same 600-16 size.

On Pontiac 27, 600-16 is a traditional numeric bias-ply size. The 600 indicates a nominal 6.00-inch section width, and the 16 identifies the wheel diameter in inches. Unlike modern metric sizing, it does not spell out an aspect ratio in the code, because that older bias-ply sizing system used a different way of describing tire proportions.

That older format matters because a modern buyer might assume the code works like a contemporary passenger tire size, and it does not. When choosing a 600-16 for Pontiac 27, treat the size code as the starting point, then compare the rim width recommendation, sidewall style, and tread type so the final tire matches the way the car is built and how it will actually be used.

Pontiac 27 uses a 16-inch rim diameter for both 1941 and 1942. The 600-16 size itself includes that wheel diameter in the code, and the available products consistently match a 16-inch rim. Several passenger-car options list recommended rim widths of 4.00 to 4.50 inches, while some specialty products broaden that usable width range slightly.

Rim diameter is the first measurement to confirm because a 16-inch tire cannot safely substitute for a different wheel size. Once that is settled, compare the wheel width and the intended look of the car, since a restored Pontiac 27 on wide whitewalls calls for a different product choice than one being set up with military NDT or truck-style tread.

Pontiac 27 tires in the sizes offered here are all bias-ply products in a traditional 600-16 format, and a tube is required. That applies across the blackwall, whitewall, double-whitewall, and military-style options listed for the Pontiac 27. Tube-type fitment is consistent with the prewar era and the construction style represented in these products.

Inner tubes are not just an accessory item on a Pontiac 27; they are part of the correct tire setup. When refreshing an older car that has been sitting, it is wise to inspect the wheels carefully for rust, sharp edges, or surface damage that could affect the tube, then pair the tires with the appropriate tube and flap arrangement if the wheel design calls for it.

For a 1941 or 1942 Pontiac 27, the listed tire size is 600-16. That means the main fitment question is usually not size variation by year, but whether the car still wears its correct 16-inch wheels and whether the chosen tire matches the intended appearance and use. The available 600-16 options include standard passenger-car bias-ply tires as well as military and truck-style tread patterns.

Start by checking the sidewall of any existing tire, measuring the wheel diameter, and comparing the wheel width to the tire’s recommended range where given. If the car is a restoration, period photos, factory literature, and marque expertise can help sort out whether a blackwall, wide whitewall, or another visual treatment is the best match for the way the Pontiac 27 is being presented.

Pontiac 27 tires are available in several sidewall styles within the 600-16 size, including blackwall, wide whitewall, and double-whitewall. Blackwall is the most common style across the offerings, while wide whitewall and double-whitewall choices are also present in passenger-car bias-ply lines. Military-style products in this size are presented as blackwall tires.

That range gives a Pontiac 27 owner some flexibility depending on whether the goal is a restrained original-style appearance or a more dressy period look. Sidewall choice also changes the visual stance of the whole car, so it is worth deciding early whether the project is aimed at formal restoration, touring presentation, or a more utilitarian setup.

Pontiac 27 tires in 600-16 are offered by BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands cover a broad mix of classic passenger-car bias-ply tires along with military and specialty tread designs. The range also includes several distinct tire series rather than a single one-brand solution.

Brand choice matters less than getting the correct size and construction, then choosing a series that suits the car’s purpose. A Pontiac 27 built for show presentation may point toward a traditional passenger-car line with the preferred sidewall styling, while a more specialized project may steer toward a military NDT or truck-oriented tread in the same 600-16 size.

Pontiac 27 tires in 600-16 are available in several series, including Silvertown Classic Bias Ply, Coker Classic Bias Ply, Firestone Classic Bias Ply, Ford Script, Excelsior Bias Ply, Lester Classic Bias Ply, Turbospeed Mk4, Tourist Crossply, Traction Mileage, Goodyear Military NDT, Deluxe All-Weather, Firestone Classic Military, Firestone Military NDT, Military NDT, NATO CJ110, and Firestone Classic Truck. All are bias-ply constructions, but they differ in styling, tread character, and intended use. Some are traditional passenger-car lines, while others are military or utility-focused patterns.

For Pontiac 27 buyers, the practical choice comes down to the role of the car. A restoration aimed at a polished prewar passenger-car look usually points toward one of the classic bias-ply passenger series, especially if whitewall styling is important, while military NDT, NATO, or truck-tread lines are better suited to specialized applications where appearance and tread character matter more than strict passenger-car presentation.

Pontiac 27 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and wide temperature swings when the tires are fitted. Keeping the tires properly inflated helps the casing hold its shape, and a prewar car benefits from being moved slightly from time to time so one section of the tire is not loaded in the same place for months on end. Long stationary storage can encourage flat spotting and stress older tube-type assemblies.

Owners who store a Pontiac 27 for a season or longer often do best with a regular inspection routine and occasional rolling movement rather than simply parking the car and forgetting it. If the car will sit for an extended period, clean the tires, keep petroleum products away from the sidewalls, and pay special attention to cracking, weathering, and wheel condition when bringing it back into use.

Tires on a Pontiac 27 should be inspected before each drive and more thoroughly at regular intervals even if the car sees very little mileage. A collector car from the early 1940s often spends long periods parked, which means age, storage conditions, tube condition, and wheel condition can matter as much as tread wear. Bias-ply tires especially deserve close attention to sidewalls, bead areas, inflation, and any signs of casing distortion.

A practical routine is to check pressure and visible condition before every outing, then perform a fuller inspection at least seasonally. On a Pontiac 27, that fuller inspection should include the spare, valve stems, wheel surfaces, and any vibration or pulling that appears when driving, because those signs can point to tire, tube, balance, or wheel issues that deserve attention before the next trip.

Tires on a Pontiac 27 should be replaced when age, cracking, hardening, impact damage, irregular wear, persistent air loss, or casing distortion appear, even if tread depth still looks usable. Collector tires often age out before they wear out, particularly on low-mileage prewar cars. Tube-type assemblies also need attention when the tire is dismounted, since a fresh outer tire does not cancel the importance of the tube and wheel condition behind it.

Tread alone is never the whole story on a Pontiac 27, especially if the car is driven only occasionally. If there is any question about sidewall integrity or long-term aging, have the tires evaluated by a specialist familiar with collector vehicles, and treat any older stored tire with extra caution before putting the car back into regular touring or event use.

The fitment covered for Pontiac 27 in 1941 and 1942 is 600-16, and the available offerings in that size include several passenger-car bias-ply series along with more specialized military-style tread options. The presence of multiple series means there is more than one period-style path within the same size. Exact original presentation for a specific Pontiac 27 can depend on how the car was configured and restored over time.

A buyer trying to match the original look of a Pontiac 27 should start with the 600-16 size, then use period photos, factory literature, and marque knowledge to sort out details such as sidewall treatment and tread style. That is especially important when choosing between a standard passenger-car tire and a more specialized military or truck-pattern alternative that may fit the wheel but present the car very differently.

Correct tire fitment can absolutely affect both the presentation and judged authenticity of a Pontiac 27. On a prewar American car, the right size, proper overall style, and an era-appropriate sidewall treatment all contribute to whether the finished car looks convincing. A technically correct 600-16 that carries the wrong visual character for the restoration can still change how the car is perceived.

That does not mean every Pontiac 27 must wear the same tire to be worthwhile, but restoration goals should guide the choice. If the car is being prepared for serious judging, compare the selected 600-16 tire against period references and club standards; if it is being built for touring, many owners accept a choice that preserves the right size while prioritizing the look they want and the use they expect.

Pontiac 27 tires in 600-16 are available as blackwall, wide whitewall, and double-whitewall depending on the product line. Any of those styles can create a period look, but they do not present the car the same way. Blackwall tends toward a more restrained factory-style appearance, while wide whitewall and double-whitewall give a more formal and visually prominent look.

The right choice depends on the exact restoration goal for the Pontiac 27 rather than on size alone. Owners usually get the best result by matching the sidewall style to period photographs, surviving unrestored examples, and the trim level or presentation style they want, because the sidewall is one of the first details people notice on a completed prewar restoration.

A properly fitted, properly maintained 600-16 bias-ply tire can be appropriate for road use on a Pontiac 27, but safety depends on the entire condition of the car, not the tire alone. Wheel integrity, tube condition, alignment, braking, steering play, and inflation all matter on an early 1940s vehicle. The specialty military-style options in this size may also drive differently from a passenger-car tread even though they share the same basic dimensions.

Road use decisions for a Pontiac 27 should reflect how the car is prepared and how it will be driven. A careful owner will treat any newly fitted set as part of a full mechanical review, then begin with shorter, slower outings to evaluate ride, tracking, vibration, and heat buildup before expecting the car to handle longer tours with confidence.

Before driving a Pontiac 27, check tire inflation, visible sidewall condition, valve stems, wheel fasteners, and any signs of tube-related air loss. On a bias-ply, tube-type setup, it is also wise to look for bulges, cuts, irregular tread wear, or a tire that appears to have shifted on the rim. Because Pontiac 27 is a prewar-era design, steering and braking condition are just as important as the tire itself.

A good pre-drive routine keeps a small tire issue from becoming a larger one on the road. Walk around the Pontiac 27 after it has moved a few feet, listen for anything unusual, and pay attention during the first miles of driving, since wandering, vibration, or pull can signal inflation, balance, alignment, or wheel problems that should be corrected before regular use.

A Pontiac 27 fitted with period-style 600-16 bias-ply tires should be driven at moderate speeds that respect the age and design of both the tire type and the car itself. Even with newly manufactured collector tires, bias-ply construction, older suspension geometry, and tube-type assemblies call for a more conservative pace than a modern car. A smooth, measured driving style is far more appropriate than sustained high-speed use.

The sensible approach is to treat a Pontiac 27 as a touring or show car, not as a highway-speed modern commuter. If the car has not been recently sorted, begin with shorter local drives and increase distance only after confirming stable temperatures, good steering response, and consistent behavior from the tires, brakes, and chassis as a complete system.
