The 1939 Oldsmobile G39 comes from the final prewar years, when American cars blended streamlined styling with comfortable road manners and substantial 16-inch wheel fitments. For many owners, tire choice on a car like this is as much about preserving the right visual character as it is about getting the car back on the road safely. The primary fitment is a 600-16 bias-ply tire, which keeps the G39 in its proper period sizing tradition. Within that size, choices include blackwall, wide whitewall, and double-whitewall styles across several classic tire series. The real decision is matching appearance, intended use, and wheel compatibility to the way the car is being restored or driven.
Which Tire Size Is Right for The 1939 Oldsmobile G39
The 1939 Oldsmobile G39 uses one primary tire size: 600-16 on a 16-inch rim, and that fitment carries through the covered sub-model. Since the size itself is straightforward, the main decision becomes choosing the right bias-ply tire style, brand, and tread character for the car's restoration goals, road use, and wheel setup.
A 600-16 is a numeric bias-ply size in which the 600 indicates an approximate 6.00-inch nominal section width and the 16 identifies the wheel diameter in inches. On a 1939 Oldsmobile G39, this is a traditional bias-ply fitment that suits the car's prewar sizing and appearance. Available choices in this size include blackwall, wide whitewall, and double-whitewall treatments from brands such as BFGoodrich, Firestone, Coker Classic, Goodyear, Avon, Lester, Excelsior, STA, Camac, and Ford Script across several vintage-style series. It is the size to evaluate when the goal is keeping the car in its proper period format while selecting the tread and sidewall presentation that best suits the vehicle.
Sub-model fitment is straightforward for the 1939 Oldsmobile G39. The covered sub-model uses the same primary tire size, so the focus stays on selecting the right bias-ply tire style and confirming the wheel setup rather than sorting through multiple fitment sizes.

Tire Size & Fitment
What tire size fits a 1939 Oldsmobile G39?
The 1939 Oldsmobile G39 uses a 600-16 tire size. That is a traditional numeric bias-ply fitment and the covered G39 Base sub-model uses the same size, so the starting point is straightforward for most owners working with a stock wheel diameter.
Once the 600-16 size is confirmed, the next step is choosing the right version within that size. Sidewall style, tread character, and rim-width compatibility can vary by product, so it is worth checking the actual wheel on the car before selecting a blackwall, wide whitewall, or double-whitewall tire.
What size rim does a 1939 Oldsmobile G39 use?
The primary tire fitment for the 1939 Oldsmobile G39 is built for a 16-inch rim. The 600-16 sizing format also confirms that the tire is intended for a 16-inch wheel, which matches the vehicle's main fitment for this page.
Rim diameter is only part of the check on a prewar car. Wheel width and the actual wheel currently installed still matter, especially if the car has had replacement wheels fitted over the years. Verifying both the 16-inch diameter and the wheel's usable width helps narrow the correct tire options within the 600-16 range.
Does the 1939 Oldsmobile G39 Base use the same tire size?
Yes. The 1939 Oldsmobile G39 Base uses the same 600-16 bias-ply tire size as the model covered here. There is no separate primary size to sort through for that sub-model, which simplifies the basic fitment question.
That shared size does not mean every 600-16 tire looks or behaves the same. Owners can still choose between different brands, sidewall presentations, and tire series depending on whether the goal is a more formal restoration-oriented appearance, a plainer blackwall look, or a specialty tread style for a specific type of use.
Choosing the Right Tire
What should I consider when choosing a 600-16 tire for a 1939 Oldsmobile G39?
Start with the correct 600-16 size and bias-ply construction, since that is the primary fitment for the 1939 Oldsmobile G39. From there, compare sidewall style, tire series, brand, and any rim-width guidance that applies to the specific tire being considered.
A prewar Oldsmobile often calls for a tire that supports both the car's look and its real use. A blackwall can create a simpler presentation, while wide whitewall or double-whitewall options create a more dressy period-style appearance. It also helps to compare load figures and confirm that the wheel dimensions on the car suit the chosen tire.
What sidewall styles are available for 1939 Oldsmobile G39 tires?
The 1939 Oldsmobile G39's 600-16 fitment is available in several sidewall styles, including blackwall, wide whitewall, and double-whitewall. Those choices all stay within the same basic size while giving the car a noticeably different visual presentation.
Sidewall style is one of the biggest appearance decisions on a prewar car. A blackwall keeps the look restrained and utilitarian, while whitewall and double-whitewall treatments add more visual emphasis around the wheel opening. The right choice usually depends on how the car is being restored and how closely the owner wants to match a period-style presentation.
What brands offer tires for the 1939 Oldsmobile G39?
Brands available in the 1939 Oldsmobile G39's 600-16 size include BFGoodrich, Firestone, Coker Classic, Goodyear, Avon, Lester, Excelsior, STA, Camac, and Ford Script. Those options cover several bias-ply series, from traditional passenger-car styles to more specialized tread patterns.
Brand alone is only one part of the decision. It helps to compare the tire series, sidewall treatment, and any stated rim-width or load specifications before narrowing the choice. On a car like the G39, visual character matters, but so does selecting a tire that suits the wheel setup and the way the car will actually be driven.
Restoration & Appearance
Which tire should I choose for a period-style 1939 Oldsmobile G39?
A period-style 1939 Oldsmobile G39 begins with the correct 600-16 bias-ply format. That keeps the tire in the same traditional sizing and construction family associated with prewar fitment, which is usually the right foundation for owners focused on visual authenticity and era-appropriate stance.
After that, the choice comes down to presentation. Blackwall, wide whitewall, and double-whitewall versions create different looks even within the same size. When exact originality matters, marque literature, period photos, and restoration references can help narrow the most appropriate sidewall treatment without assuming every 600-16 option matches the way the car originally left the factory.
Does correct tire fitment matter for a 1939 Oldsmobile G39 restoration?
Yes, correct tire fitment matters because it affects both the appearance and the overall stance of a 1939 Oldsmobile G39. Staying with the proper 600-16 bias-ply fitment keeps the car in the right sizing family for a prewar restoration-oriented presentation.
Fitment accuracy also influences practical details such as wheel compatibility and body clearance. A restoration can look visually off if the tire profile, sidewall treatment, or tread style does not suit the car's era. Even when the goal is a driver rather than a show car, choosing the right size and general construction helps preserve the G39's character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1939 Oldsmobile G39?
Yes. Even though the primary fitment is 600-16, modifications can change what works on a 1939 Oldsmobile G39. Replacement wheels, altered wheel width, brake changes, suspension work, or body repairs can all affect clearance and the way a tire sits on the car.
A car that has been lowered, fitted with non-original wheels, or rebuilt with different components should be measured rather than assumed. Checking wheel diameter, wheel width, steering clearance, and fender space before installing new tires helps prevent surprises, especially on older vehicles that may have seen decades of repairs or updates.
What should I inspect before driving a 1939 Oldsmobile G39 on new tires?
Before road use, inspect the wheels, valve hardware, and overall wheel condition, then confirm the tires are seated properly and inflated appropriately for their intended use. On a 1939 Oldsmobile G39, it also makes sense to look over the suspension, steering components, and brake system before treating new tires as the final step.
Collector cars often sit for long periods, so a broader safety check matters. Look for looseness in the front end, uneven ride height, rubbing points, and any signs that the wheels are out of true. A careful short test drive, followed by another visual inspection, helps catch clearance or air-retention issues before longer trips.
How should 600-16 tires on a collector 1939 Oldsmobile G39 be maintained?
600-16 tires on a collector 1939 Oldsmobile G39 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long exposure to sunlight, moisture, and ozone sources. Low annual mileage does not remove the need for routine checks on an older collector vehicle.
Storage habits make a difference on cars that are not driven often. Keeping the car in a stable environment and checking for air loss before each outing helps preserve the tires and supports better road manners. It is also wise to inspect the spare and recheck the wheel hardware anytime the tires are removed or rotated.
