The 1938 Oldsmobile 8 Cyl. came from a period when American cars were growing more streamlined, more refined, and more comfortable on longer roads. For many collectors, that makes this Oldsmobile as much about proper stance and road manners as it is about prewar styling. This car uses a 700-16 bias-ply tire on a 16-inch rim, so the main fitment decision is less about size choice and more about selecting the right period-style tire within that format. Available options include blackwall and wide whitewall presentations across several classic bias-ply series. The right choice depends on whether the goal is restoration-minded appearance, traditional construction, or careful road use preparation.
Which Tire Size Is Right for The 1938 Oldsmobile 8 Cyl.
The 1938 Oldsmobile 8 Cyl. uses one primary tire size: 700-16. That means the fitment question is straightforward, with a bias-ply tire mounted on a 16-inch rim, including the covered Base sub-model. The real decision is choosing the right version of that size for the car's appearance, intended use, and wheel compatibility.
In a numeric bias-ply size such as 700-16, the 700 designates an approximate 7.00-inch nominal section width and the 16 identifies the wheel diameter in inches. This is a traditional bias-ply fitment that suits the prewar character and visual proportions of the 1938 Oldsmobile 8 Cyl. Within this size, there are blackwall and wide whitewall choices from brands including BFGoodrich, Firestone, Lester, Avon, Tornel, and STA, with series ranging from classic passenger designs to military and truck-style patterns. Selecting among them comes down to the look you want, the wheel specification you have, and how the car will actually be driven.
Sub-model fitment is simple for the 1938 Oldsmobile 8 Cyl., because the covered configuration uses the same primary tire size. Checking the exact sub-model still matters so the tire choice matches the car's wheel setup and the appearance you want to preserve.

1938 Oldsmobile 8 Cyl. Base
The 1938 Oldsmobile 8 Cyl. Base uses the same 700-16 bias-ply tire format as the main model fitment. That makes selection more about choosing between blackwall, wide whitewall, and the available tire series while confirming the wheel remains a 16-inch setup.
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.
Best 1938 Oldsmobile 8 Cyl. Tires for Sale

These FAQs for the 1938 Oldsmobile 8 Cyl. focus on the 700-16 tire size, 16-inch rim fitment, bias-ply construction, appearance choices such as blackwall or wide whitewall, and the checks that matter before putting a prewar car back on the road.
Tire Size & Fitment
What tire size fits a 1938 Oldsmobile 8 Cyl.?
The 1938 Oldsmobile 8 Cyl. uses a 700-16 tire size. This is a numeric bias-ply fitment on a 16-inch rim, and the covered Base sub-model uses that same primary size as well.
That makes size selection fairly direct, but the car still needs the correct wheel setup to match. Once 700-16 is confirmed, the choice shifts to tire style and purpose, such as blackwall or wide whitewall appearance, plus whether the car is being kept in a restoration-oriented presentation or prepared for regular collector road use.
What size rim does a 1938 Oldsmobile 8 Cyl. use?
The 1938 Oldsmobile 8 Cyl. uses a 16-inch rim with its 700-16 tire size. Several of the available 700-16 tire options are built around a 4.50 to 5.50 inch rim-width range, which is a useful reference when checking the wheel already on the car.
Rim diameter is the first point to confirm, especially on an older vehicle that may have seen wheel changes over the years. After that, inspect actual wheel width and condition so the tire matches the wheel properly and maintains the intended stance without creating unnecessary mounting or clearance issues.
Does the 1938 Oldsmobile 8 Cyl. Base use the same tire size?
Yes. The 1938 Oldsmobile 8 Cyl. Base uses the same 700-16 bias-ply tire size as the covered model core. There is no separate primary size change between the Base fitment and the main listing here.
That consistency keeps the fitment process simple, but it does not remove the need to verify the actual wheels on the car. A restoration-minded owner may focus on sidewall presentation, while a driver may compare series, load figures where stated, and wheel-width suitability within the same 700-16 size.
Choosing the Right Tire
What should I consider when choosing a 700-16 tire for a 1938 Oldsmobile 8 Cyl.?
Start with the basics: the 1938 Oldsmobile 8 Cyl. uses a 700-16 bias-ply tire on a 16-inch rim. From there, compare the tire's intended character, whether it is a classic passenger design or a more specialized military or truck-style pattern, along with any stated rim-width and load specifications.
Appearance is a major part of the decision on a prewar Oldsmobile. A wide whitewall creates a very different presentation than a blackwall, and the tire series can influence both the look and the way the car suits a restoration plan, touring use, or a more utility-oriented setup.
What sidewall styles are available for 1938 Oldsmobile 8 Cyl. tires?
The available 700-16 tires for the 1938 Oldsmobile 8 Cyl. include blackwall and wide whitewall sidewall styles. Both are offered within bias-ply construction, so the choice is mainly about appearance rather than changing the tire's fundamental period-style construction.
Wide whitewalls generally suit a more formal prewar presentation, while blackwalls give the car a plainer and more understated look. The best choice depends on how the Oldsmobile is being finished, the visual balance of the wheel and trim, and whether the goal is show presentation or practical road use.
What brands offer tires for the 1938 Oldsmobile 8 Cyl.?
700-16 tire options for the 1938 Oldsmobile 8 Cyl. are available from Lester, Avon, BFGoodrich, Firestone, Tornel, and STA. Those choices include classic bias-ply passenger tires as well as some military and truck-style patterns within the same general size family.
Brand alone is only part of the decision. It helps to compare sidewall style, tire series, stated rim-width compatibility, and load figures where they are shown, then match those details to the way the Oldsmobile will be presented and driven rather than assuming every 700-16 serves the same purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1938 Oldsmobile 8 Cyl.?
A period-style starting point for a 1938 Oldsmobile 8 Cyl. is a 700-16 bias-ply tire, since that is the primary fitment for the car. Within that size, the choice usually comes down to whether the car looks more appropriate with a blackwall or a wide whitewall presentation.
For many restorations, overall visual balance matters as much as the tire size itself. Owners chasing exact historical authenticity should compare the tire choice with marque references, surviving photos, or other vehicle-specific documentation, while owners building a roadable collector car may simply focus on a traditional prewar look.
Does correct tire fitment matter for a 1938 Oldsmobile 8 Cyl. restoration?
Yes, correct tire fitment has a strong effect on the finished look of a 1938 Oldsmobile 8 Cyl. The proper 700-16 bias-ply size helps preserve the car's stance, fills the wheel opening in the right way, and supports the visual character expected from a late-1930s American car.
Even small changes in tire type can alter how a restored car sits and presents. That is why owners often pay close attention to sidewall treatment, wheel dimensions, and the overall style of the tire, not just whether it mounts on the rim and holds air.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1938 Oldsmobile 8 Cyl.?
Yes. A 1938 Oldsmobile 8 Cyl. may have the correct 700-16 tire size on paper, but aftermarket wheels, changed wheel widths, brake conversions, suspension work, or body alterations can all affect how that tire actually sits and clears.
Older cars often pass through several owners, so it is worth measuring what is on the vehicle rather than assuming it remains stock. Confirm the 16-inch wheel diameter, inspect wheel width, and check steering and fender clearance before mounting a new set, especially if the car has been modified at any point.
What should I inspect before driving a 1938 Oldsmobile 8 Cyl. on new tires?
Before driving, inspect the wheels, valve hardware, and overall mounting condition along with the tires themselves. The 1938 Oldsmobile 8 Cyl. should also be checked for proper inflation, secure lug hardware, visible sidewall damage, and enough clearance at full steering lock and through suspension movement.
A prewar car benefits from a broader road-readiness check as well. Look at steering play, brake function, wheel bearing condition, and any signs that the car has been sitting for long periods, because new tires perform best when the surrounding chassis and wheel components are equally ready for use.
How should 700-16 tires on a collector 1938 Oldsmobile 8 Cyl. be maintained?
Collector-car 700-16 tires should be inspected regularly for pressure loss, tread wear, sidewall cracking, cuts, bulges, and changes in how the car sits after storage. Bias-ply tires on a lightly used 1938 Oldsmobile 8 Cyl. also deserve periodic checks even when tread wear is minimal.
Storage conditions matter almost as much as mileage on a prewar vehicle. Keeping the car away from prolonged sun, heat, moisture, and ozone sources helps preserve the tires, and routine inspection before each drive is a smart habit when the Oldsmobile is used only occasionally rather than every week.
