1939 Pontiac 25 Tires

The 1939 Pontiac 25 uses a 600-16 tire size. This is a numeric bias-ply format, and it is the primary fitment for the covered vehicle and sub-model here. The size is built for a 16-inch rim and reflects the prewar tire sizing system commonly seen on cars of this period.

Once 600-16 is confirmed, the next step is choosing the version that matches the car’s needs. Options in this size include blackwall, wide whitewall, and double-whitewall styles across several tire series. It is also worth checking the actual wheel width on the car, especially if the wheels have been changed over the years.

The 1939 Pontiac 25 uses a 16-inch rim with its 600-16 tire fitment. That rim diameter is built directly into the tire size itself, with the final number in 600-16 identifying the wheel diameter. The available tire options for this car are centered on that same 16-inch rim size.

Rim diameter is only part of the fitment picture, so it helps to confirm wheel width as well before choosing among available tires. Many 600-16 options in this group are intended for relatively narrow vintage wheels. A car with later replacement wheels, altered brakes, or mixed wheel sets should be inspected carefully before mounting tires.

Yes. The 1939 Pontiac 25 Quality 6 Cyl. uses the same 600-16 bias-ply tire size as the covered 1939 Pontiac 25 fitment overall. That keeps size selection simple and avoids the need to sort through multiple primary tire sizes for this particular sub-model.

With the size staying consistent, the main decision becomes how the tire should look and how the car will be driven. A restoration-oriented car may lean toward a traditional whitewall presentation, while another owner may prefer blackwalls. Wheel condition, rim width, and overall clearance still deserve a check before any new set goes on the car.

Start with the correct primary fitment: 600-16 on a 16-inch rim. From there, compare the available bias-ply options by sidewall style, tire series, rim-width specification, and how closely the tire’s visual character matches the way the Pontiac is being restored, shown, or driven.

Some owners want a formal prewar look with a wide whitewall, while others prefer a simpler blackwall presentation. Product details such as load figures, weight, and wheel-width range can also matter, especially if the car will see regular touring. A careful match between the tire and the actual wheel on the car helps avoid unwanted fitment surprises.

The 1939 Pontiac 25’s 600-16 tire choices include blackwall, wide whitewall, and double-whitewall styles. Those sidewall treatments can change the car’s overall presentation quite a bit, even when the tire size itself remains the same. The construction remains bias-ply across the available options in this fitment group.

A blackwall usually gives the car a more understated look, while whitewall and double-whitewall versions create a stronger period-style visual statement. Appearance should be balanced with the way the Pontiac is actually used, since a frequently driven car may be selected differently than a show-focused restoration. Tire size and wheel compatibility still come first.

The 1939 Pontiac 25’s 600-16 size is available from several brands, including BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those brands appear across multiple classic bias-ply and specialty series, giving buyers more than one approach within the same primary fitment.

Brand alone should not decide the choice. It is more useful to compare each tire’s sidewall style, series character, rim-width specification where given, and whether the tread and visual presentation suit a passenger-car restoration or another type of vintage use. The best comparison starts after the 600-16 size and 16-inch wheel are both confirmed.

A period-style 1939 Pontiac 25 starts with the correct primary fitment, which is 600-16 in a bias-ply construction. From there, the choice usually comes down to the look you want the car to project, with available options ranging from blackwall to wide whitewall and double-whitewall versions in several traditional tire series.

For many restorations, the tire’s visual character matters almost as much as the size itself because it shapes the car’s stance and overall era impression. If exact historical accuracy is the goal, compare the tire style against marque references, period photos, or other vehicle-specific documentation. A road-driven restoration may place more emphasis on practical maintenance and wheel condition.

Yes, correct tire fitment matters on a 1939 Pontiac 25 restoration because the tire is a major visual element and a key part of how the car sits on its wheels. Staying with the proper 600-16 bias-ply size keeps the restoration aligned with the car’s prewar proportions and traditional tire presentation.

Even a visually small change in size, sidewall treatment, or wheel setup can alter the car’s stance more than many owners expect. A restoration-minded buyer should verify the wheel diameter and width already on the car, then choose the sidewall style that best supports the intended finish. That approach keeps appearance and fitment working together rather than competing.

Yes, modifications can affect tire fitment on a 1939 Pontiac 25 even when the intended tire size remains 600-16. Changes such as replacement wheels, altered suspension height, brake conversions, or body repairs around the fender openings can all influence how much clearance the car has for a vintage-style bias-ply tire.

A Pontiac that still carries its original-style wheel setup is usually easier to evaluate than one that has been updated over time. Checking wheel diameter, actual wheel width, and clearance at full steering lock helps prevent problems before mounting new tires. It is also smart to inspect whether all four wheels on the car are the same.

Before driving a 1939 Pontiac 25 on new tires, inspect the wheels, valve hardware, and overall mounting condition, then confirm that the tires are inflated appropriately for the chosen tire and wheel setup. It also helps to check for brake drag, loose steering components, and any suspension wear that could affect how the car tracks.

A short, careful road test is the best first step after installation. Listen for rubbing, feel for pull or vibration, and recheck pressure after the first drive. Vintage cars that have been parked for long periods also deserve a second look at wheel fasteners, bearing condition, and signs of fluid leakage before any longer run on public roads.

Collector-car 600-16 tires should be maintained with regular pressure checks, visual inspections, and careful storage habits. On a 1939 Pontiac 25, that means watching for sidewall cracking, bulges, cuts, uneven wear, and slow air loss, even if the car is driven only occasionally and the tread still looks serviceable.

Long periods of inactivity can be just as hard on vintage tires as road miles. Keeping the Pontiac in a cool, dry space away from prolonged sunlight and ozone sources helps preserve tire condition. A car that sits for extended intervals also benefits from periodic inspection of the contact patch and wheel area before it returns to normal road use.
