The 1941 Pontiac 25 comes from a transitional prewar moment, when American cars balanced streamlined styling with durable road manners suited to everyday driving. For owners restoring one today, tire choice plays a major role in preserving that substantial 1940s character. This Pontiac 25 uses a 600-16 bias-ply tire on a 16-inch rim, keeping the fitment firmly in vintage territory. Within that size, there is still meaningful choice in blackwall, wide whitewall, and double-whitewall presentations across several classic tire series and brands. The real decision is matching the right 600-16 tire to the car’s intended appearance, wheel setup, and road use.
Which Tire Size Is Right for The 1941 Pontiac 25
The 1941 Pontiac 25 uses one primary tire size: 600-16. That is a bias-ply fitment for a 16-inch rim, and the covered Deluxe 6 Cyl. sub-model uses the same size, so the main choice is not between multiple primary sizes but between period-style tread, sidewall appearance, brand, and how closely you want to stay with traditional bias-ply construction.
A 600-16 size uses the older numeric bias-ply system, where the leading number represents an approximate 6.00-inch nominal section width and the final number identifies a 16-inch rim. On a 1941 Pontiac 25, this size keeps the car in its original-era bias-ply fitment style, which matters for both stance and overall visual character. Available choices include blackwall, wide whitewall, and double-whitewall versions from brands such as BFGoodrich, Firestone, Coker Classic, Goodyear, Avon, Lester, and others across several tire series. Choosing within 600-16 comes down to the look you want, the wheel width in use, and whether the car is being restored, shown, or driven regularly.
Sub-model fitment is straightforward for the covered 1941 Pontiac 25 range. The Deluxe 6 Cyl. uses the same primary tire size, so checking the sub-model mainly helps confirm that you can focus on tire style, sidewall treatment, and wheel compatibility rather than sorting through multiple fitment sizes.

1941 Pontiac 25 Deluxe 6 Cyl.
The 1941 Pontiac 25 Deluxe 6 Cyl. uses the same 600-16 bias-ply tire fitment as the core vehicle listing. That keeps tire selection centered on period-style appearance, tread character, and confirming that the existing 16-inch wheels match the tire’s intended rim-width range.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1941 Pontiac 25?
The 1941 Pontiac 25 uses a 600-16 tire size. This is a numeric bias-ply size mounted on a 16-inch rim, and the covered Deluxe 6 Cyl. sub-model uses the same primary fitment.
That makes the main decision less about finding the correct size and more about choosing the right version within 600-16. Sidewall style, tread character, and wheel-width compatibility all matter, especially if the car has been restored, stored for long periods, or fitted with replacement wheels at some point in its life.
What size rim does a 1941 Pontiac 25 use?
The primary tire fitment for the 1941 Pontiac 25 is built around a 16-inch rim. The 600-16 tire size confirms that wheel diameter, and available products in this size are designed for 16-inch applications.
Wheel diameter is only one part of the fitment picture on a prewar car. It is still important to confirm the actual wheel on the vehicle, especially if the Pontiac has replacement rims or later service parts, and to compare the wheel width with the rim-width range shown for the tire you are considering.
What does 600-16 mean on a 1941 Pontiac 25?
In 600-16, the 600 portion is the vintage numeric bias-ply size designation and corresponds to an approximate 6.00-inch nominal section width. The 16 identifies the rim diameter in inches, so the tire is intended for a 16-inch wheel.
This older sizing system does not read like a modern metric radial size, which is why it often causes confusion during restoration work. For a 1941 Pontiac 25, understanding that 600-16 is a traditional bias-ply fitment helps keep the search focused on the right construction, correct wheel diameter, and period-appropriate appearance.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1941 Pontiac 25?
Start with the basics: the 1941 Pontiac 25 uses a 600-16 bias-ply tire on a 16-inch rim. From there, the key differences are sidewall style, tire series, rim-width compatibility, load figures where shown, and whether the tire is aimed more at passenger-car presentation or military and truck-style use.
A blackwall can suit a restrained driver-quality look, while wide whitewall and double-whitewall options create a much stronger prewar visual statement. It also helps to check the actual wheels on the car, because some 600-16 products call out specific rim-width ranges such as 4.00 to 4.50 inches or 4.0 to 5.0 inches.
What sidewall styles are available for 1941 Pontiac 25 tires?
The 600-16 fitment for a 1941 Pontiac 25 is available in blackwall, wide whitewall, and double-whitewall styles. Those appearance choices span several brands and tire series, so the visual character of the car can change quite a bit even while staying within the same primary size.
Choosing a sidewall style depends on how the Pontiac is being presented. A restoration-oriented build may lean toward a traditional whitewall treatment, while a simpler blackwall can suit a more understated driver. When appearance matters, compare the sidewall treatment alongside tread pattern and overall tire series rather than selecting by size alone.
What brands offer tires for the 1941 Pontiac 25?
The 600-16 size for a 1941 Pontiac 25 is available from BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, and Camac. Those options cover a broad mix of classic passenger-style tires along with military and truck-oriented bias-ply offerings.
Brand choice should be tied to the kind of car you are building and the look you want, not just the name on the sidewall. Compare each option by sidewall style, tire series, intended use, stated rim-width fitment, and any load specification shown for the version you are considering.
Restoration & Appearance
Which tire should I choose for a period-style 1941 Pontiac 25?
A period-style 1941 Pontiac 25 starts with the correct primary size and construction, which here means a 600-16 bias-ply tire. From there, the choice usually comes down to whether the car looks right to you with a blackwall, wide whitewall, or double-whitewall presentation and which classic tire series best matches the build.
For many prewar restorations, tire appearance has a major effect on the car’s stance and personality. If exact historical presentation matters, compare your preferred tire against marque references, period photos, and restoration documentation, because the right-looking tire is not always the same as a universally correct one.
Does correct tire fitment matter for a 1941 Pontiac 25 restoration?
Correct tire fitment matters a great deal on a 1941 Pontiac 25 because tire size and construction strongly influence the car’s visual balance. Staying with the 600-16 bias-ply format keeps the wheel diameter, sidewall shape, and overall presentation in line with what buyers expect from a prewar Pontiac.
Restoration decisions are not only about appearance. The actual wheel width, the tire’s intended rim range, and the condition of the wheels themselves also deserve attention before mounting new tires. Even a well-restored car can lose authenticity and drivability if the tire profile or wheel match is overlooked.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1941 Pontiac 25?
Yes, modifications can affect tire fitment on a 1941 Pontiac 25 even when the intended size remains 600-16. Replacement wheels, brake conversions, altered ride height, suspension repairs, or bodywork changes can all influence how a vintage bias-ply tire sits and clears on the car.
A Pontiac that still wears original-style wheels is usually easier to size correctly than one with later parts mixed in. Check wheel diameter and width first, then inspect steering clearance, fender clearance, and tire-to-suspension spacing before assuming a new 600-16 will suit the car exactly as expected.
What should I inspect before driving a 1941 Pontiac 25 on new tires?
Before driving a 1941 Pontiac 25 on new tires, inspect the wheels, valve stems, wheel hardware, and overall condition of the suspension and steering. The tires themselves should be checked for proper inflation, secure mounting, and any signs of interference once the car is back on the ground.
A short, careful test drive is worthwhile after installation, especially on a collector car that may have sat for long periods. Listen for rubbing in turns, recheck air pressure after the first miles, and look for uneven contact that might point to alignment, brake drag, or wheel-condition issues.
How should 600-16 tires on a collector 1941 Pontiac 25 be maintained?
Collector-car 600-16 tires should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to heat, sunlight, and ozone sources. On a 1941 Pontiac 25 that is driven only occasionally, age and storage condition matter as much as tread depth.
Regular movement helps prevent flat spotting and keeps the car from sitting on one section of the casing for too long. It also helps to inspect the spare, check for slow air loss between drives, and look over the wheels and tubes where applicable before taking the Pontiac on a longer outing.
