The 1967 Oldsmobile 88 Series sat squarely in the full-size American car market, where comfort, presence, and traditional road manners mattered as much as styling. Buyers restoring or maintaining one today usually want a tire that matches that big Oldsmobile character rather than a generic modern substitute. This model uses 14-inch bias-ply fitments, with 855-14 and H78-14 both applicable to the 1967 Oldsmobile 88 Series Base. That opens the door to different period-style looks, including narrow whitewall and wide whitewall presentations, along with modern radial-equivalent sizing for owners considering a different construction. The key is matching the tire to the car's wheels, appearance goals, and intended use.
Which Tire Size Is Right for The 1967 Oldsmobile 88 Series
The 1967 Oldsmobile 88 Series uses two primary tire sizes, and both are bias-ply fitments on 14-inch rims. Since the covered Base sub-model is associated with both 855-14 and H78-14, the decision is less about rim diameter and more about the tire sizing system, sidewall appearance, and whether a period-style bias-ply or a radial-equivalent path makes the most sense for the car.
An 855-14 numeric bias-ply size uses the first number to express nominal section width, in this case about 8.55 inches, while the final number identifies a 14-inch rim. On a 1967 Oldsmobile 88 Series, this is a traditional full-size car fitment with classic bias-ply construction and the upright sidewall look many restorers expect. Available choices in this size center on BFGoodrich Silvertown Classic Bias Ply tires with narrow whitewall treatments, including different whitewall widths. It is a strong choice for owners aiming to preserve a period-style presentation and a traditional bias-ply driving feel.
H78-14 is a vintage alphanumeric bias-ply size in which the letter identifies the tire's size class, the series number identifies the profile family, and the final number again points to a 14-inch rim. For the 1967 Oldsmobile 88 Series, it remains a bias-ply option with the broad-shouldered look typical of late-1960s American fitments. In this size, the available product uses the Coker Classic Bias Ply series with a wide whitewall sidewall style. That makes H78-14 especially relevant for owners who want a more pronounced whitewall appearance while staying with a traditional bias-ply construction.
Sub-model fitment is straightforward here because the covered 1967 Oldsmobile 88 Series Base is associated with the same two 14-inch bias-ply tire sizes. The important choice is deciding which of those sizes and sidewall presentations best suits the car's wheels, appearance, and driving plans.

1967 Oldsmobile 88 Series Base
The 1967 Oldsmobile 88 Series Base uses the same two primary 14-inch bias-ply fitments found at the model level: 855-14 and H78-14. That gives the owner room to choose between a narrower whitewall presentation or a wider whitewall look, while also comparing the available radial-equivalent sizing before changing construction.
Bias-Ply to Radial Tire Conversion for the 1967 Oldsmobile 88 Series
Both 855-14 and H78-14 have three radial-equivalent options available. For either primary size, 215R14 is the 80-series metric radial equivalent, P225/75R14 is the P-metric 75-series radial equivalent, and P235/70R14 is the P-metric 70-series radial equivalent. These choices move from a traditional Euro-metric radial format to progressively lower-profile P-metric alternatives. A recommended rim-width range of 5 to 7 inches applies to these equivalents, and wheel width, overall dimensions, and vehicle clearance should be checked before any conversion.

Best 1967 Oldsmobile 88 Series Tires for Sale
Available 1967 Oldsmobile 88 Series tires focus on bias-ply 14-inch fitments from BFGoodrich and Coker Classic. The product mix gives buyers a choice between Silvertown Classic Bias Ply and Coker Classic Bias Ply series, with narrow whitewall and wide whitewall sidewall styles.
These 1967 Oldsmobile 88 Series tire FAQs focus on the two primary 14-inch bias-ply sizes, radial-equivalent options, whitewall choices, and the fitment checks that matter before putting a full-size Oldsmobile back on the road.
Tire Size & Fitment
What tire size fits a 1967 Oldsmobile 88 Series?
The 1967 Oldsmobile 88 Series uses two primary tire sizes: 855-14 and H78-14. Both are bias-ply fitments for 14-inch wheels, and the covered Base sub-model is associated with both sizes rather than with a separate sub-model-specific tire choice.
That means the main decision is not wheel diameter but which sizing system and visual presentation best suits the car. Before choosing between them, confirm the actual wheel setup on the vehicle, especially if it has been changed over the years, then compare the available whitewall styles, construction goals, and any planned move to a radial-equivalent size.
What size rim does a 1967 Oldsmobile 88 Series use?
Both primary tire sizes for the 1967 Oldsmobile 88 Series are built around a 14-inch rim diameter. That applies to the 855-14 numeric bias-ply size and the H78-14 alphanumeric bias-ply size used on the covered Base model.
Rim diameter is only part of the fitment picture, especially on an older full-size car that may no longer have its original wheels. It is worth checking the wheel's actual width as well, since the available bias-ply products and the radial-equivalent sizes each have their own rim-width considerations before a tire is selected.
What does 855-14 mean on a 1967 Oldsmobile 88 Series?
855-14 is a numeric bias-ply tire size. The 855 portion refers to the tire's nominal section width, approximately 8.55 inches, and the 14 identifies the rim diameter in inches.
For a 1967 Oldsmobile 88 Series, that size points to a traditional bias-ply fitment rather than a modern metric radial format. Buyers who see 855-14 on the car should use it as a starting point for choosing a period-style replacement, then compare sidewall appearance, wheel-width compatibility, and any radial-equivalent alternatives before making a change.
Bias-Ply & Radial Options
Is 855-14 a bias-ply or radial tire for the 1967 Oldsmobile 88 Series?
855-14 is a bias-ply tire size on the 1967 Oldsmobile 88 Series. It is one of the two primary fitments used on 14-inch rims, and the available products in that size follow the traditional bias-ply construction associated with late-1960s full-size American cars.
That matters because a bias-ply tire affects both the car's appearance and its on-road character. Owners who want to keep a period-style presentation often stay with that construction, while anyone considering a radial alternative should compare the equivalent sizes carefully and verify wheel width, tire dimensions, and clearance before changing over.
What radial tire sizes are equivalent to 855-14?
Radial equivalents for 855-14 include 215R14 as the 80-series metric radial option, P225/75R14 as the 75-series P-metric radial option, and P235/70R14 as the 70-series P-metric radial option. These are alternative sizing formats rather than additional primary factory-style fitments.
Each equivalent gives a different way to approach a radial conversion while staying on a 14-inch rim. The recommended rim-width range for these equivalents is 5 to 7 inches, and the owner should still confirm wheel width, overall tire dimensions, and steering or fender clearance before treating any of them as a workable substitute.
What should I check before converting my 1967 Oldsmobile 88 Series from bias-ply to radial tires?
Start by confirming the exact primary size on the car, then compare it with the available radial equivalents: 215R14, P225/75R14, or P235/70R14 for either 855-14 or H78-14. The wheel must remain a 14-inch rim, and the recommended rim-width range for those equivalents is 5 to 7 inches.
A conversion also calls for practical checks beyond size labels. Measure the actual wheel width, inspect front and rear clearance through steering and suspension travel, and consider whether the car's current setup, ride height, or wheel choice has changed from stock over time.
Choosing the Right Tire
What should I consider when choosing a 855-14 tire for a 1967 Oldsmobile 88 Series?
A 855-14 tire choice starts with keeping the correct 14-inch bias-ply fitment, then narrowing the decision by sidewall appearance and wheel compatibility. In this size, the available BFGoodrich Silvertown Classic Bias Ply options use narrow whitewall styling and a rim-width range of 5.50 to 6.00 inches.
That makes 855-14 a strong fitment for owners who want a traditional bias-ply look without moving to a wider whitewall treatment. It also helps to compare load capacity, product weight, and the car's intended use, especially if the Oldsmobile is driven regularly rather than shown or stored most of the time.
What sidewall styles are available for 1967 Oldsmobile 88 Series tires?
The available sidewall styles for the 1967 Oldsmobile 88 Series are narrow whitewall and wide whitewall. Narrow whitewall appears in the 855-14 BFGoodrich Silvertown Classic Bias Ply offerings, while wide whitewall appears in the H78-14 Coker Classic Bias Ply option.
That difference can shape the car's finished look as much as the size itself. A narrower stripe usually gives a restrained late-1960s presentation, while a wider whitewall creates a more formal traditional appearance, so the final choice should match the vehicle's restoration direction and the look of its wheels and trim.
What brands offer tires for the 1967 Oldsmobile 88 Series?
The available brands for the 1967 Oldsmobile 88 Series are BFGoodrich and Coker Classic. BFGoodrich appears in the 855-14 size through the Silvertown Classic Bias Ply series, while Coker Classic appears in H78-14 through the Coker Classic Bias Ply series.
Choosing between them is less about ranking brands and more about matching the tire to the size and look you want on the car. Since each brand is tied here to a different size and whitewall presentation, the better comparison is fitment, sidewall style, and wheel-width suitability rather than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Oldsmobile 88 Series?
For a period-style 1967 Oldsmobile 88 Series, the starting point is one of the two primary bias-ply sizes: 855-14 or H78-14. Staying with a bias-ply construction preserves the traditional sizing format and visual character that suit a late-1960s full-size Oldsmobile.
From there, the better choice depends on the look you want the car to carry. The available 855-14 options use narrow whitewalls, while H78-14 is offered with a wide whitewall, so the final decision often comes down to restoration theme, wheel appearance, and whether the car is meant to lean more formal or understated.
How does tire construction affect the appearance of a restored 1967 Oldsmobile 88 Series?
Tire construction changes more than ride feel on a restored 1967 Oldsmobile 88 Series; it also changes visual character. A bias-ply tire keeps the vintage sizing format and profile associated with the car's era, while a radial alternative introduces a more modern tire presentation even when the rim diameter stays the same.
That is why many restoration-oriented owners begin with the original-style bias-ply sizes and then decide whether appearance or road-use priorities matter more. When exact originality is important, the safest approach is to compare the car against marque-specific historical references before settling on a particular size, whitewall treatment, or construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Oldsmobile 88 Series?
Yes, modifications can affect tire fitment on a 1967 Oldsmobile 88 Series even when the car still uses one of its correct 14-inch tire sizes. Aftermarket wheels, changes in wheel width, altered ride height, suspension work, or body and brake updates can all change the space available around the tire.
That is especially important when moving from a primary bias-ply size to a radial equivalent. A car that has been lowered or fitted with different wheels should have its steering clearance, fender clearance, and actual wheel dimensions checked before new tires are chosen simply by size code alone.
What should I inspect before driving a 1967 Oldsmobile 88 Series on new tires?
Before driving a 1967 Oldsmobile 88 Series on new tires, inspect the wheels, valve stems, and the surrounding suspension and steering components. It also helps to confirm that all four tires match the intended size and construction, and that inflation is set appropriately for the tire being used.
A brief road-use check should follow once the tires are mounted. Look for any rubbing at full steering lock, confirm that the tires seat and run evenly, and recheck air pressure after the first drives so the car is not being judged on an installation issue instead of the tire itself.
How should 855-14 tires on a collector 1967 Oldsmobile 88 Series be maintained?
855-14 tires on a collector 1967 Oldsmobile 88 Series should be maintained with regular pressure checks, routine visual inspections, and attention to age as well as tread. A low-mileage collector car can still develop sidewall cracking, flat spotting, air loss, or general deterioration if it sits for long periods.
Storage conditions matter just as much as driving habits. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and occasional inspections of tread, sidewalls, and overall condition make it easier to catch problems before the Oldsmobile returns to regular road use.
