The 1967 Ford Thunderbird came at a moment when Ford’s personal luxury coupe had grown into a larger, more formal car, with styling and road manners aimed as much at presence and comfort as outright sport. That character matters when choosing tires, because this Thunderbird uses 15-inch bias-ply fitments and the exact size depends on the specific sub-model. Period-style options center on numeric bias-ply sizes such as 855-15 and 815-15, with available whitewall and whitewall-redline treatments, and there is also a modern radial-equivalent path for 855-15. The right choice comes down to confirming the exact configuration, then balancing appearance, construction, and intended road use.
Which Tire Size Is Right for The 1967 Ford Thunderbird
The 1967 Ford Thunderbird uses four primary tire sizes, and the correct one depends on the sub-model rather than a change in rim diameter or basic construction. All of these fitments are bias-ply tires for 15-inch rims, so the first step is identifying whether the car is an All Other Models configuration or a Tudor Non-Air car before comparing tire choices.
An 8.45-15 numeric bias-ply size uses the first number to indicate approximate nominal section width in inches, while the final number identifies a 15-inch rim. This is a traditional bias-ply fitment for certain 1967 Ford Thunderbird configurations, matching the period sizing system these cars used. Buyers looking at this size should focus on maintaining the proper vintage fitment approach and confirming that the car’s actual wheel setup still matches the original 15-inch application. It is best suited to owners who want to stay with the Thunderbird’s original-style tire format rather than convert to a modern radial equivalent.
The 855-15 size is a numeric bias-ply designation, with 8.55 representing the tire’s nominal width class and 15 indicating the rim diameter. On the 1967 Ford Thunderbird, this size keeps the period-style bias-ply construction while also offering the broadest set of related choices, including BFGoodrich Silvertown Classic Bias Ply tires in narrow whitewall versions. It is also the one primary Thunderbird size here with clearly defined modern radial-equivalent alternatives. That makes 855-15 especially important for owners deciding between a traditional restoration-oriented presentation and a more modern construction path.
An 8.25-15 tire follows the same vintage numeric bias-ply format, with the leading number referring to approximate section width and the 15 identifying the wheel diameter. This size applies to a specific 1967 Ford Thunderbird sub-model grouping, so it should not be treated as universal across every car wearing the Thunderbird name that year. Because the fitment remains bias-ply, the practical goal is preserving the proper tire format and wheel relationship for the vehicle’s configuration. Owners should confirm the exact sub-model and current wheel setup before selecting this narrower numeric size.
The 815-15 designation is another vintage numeric bias-ply size, indicating an approximate 8.15-inch width class on a 15-inch rim. For the 1967 Ford Thunderbird, it belongs to the Tudor Non-Air fitment group and is available in BFGoodrich Silvertown Classic Bias Ply form with either a narrow whitewall or a whitewall-redline appearance. That gives this size more visual choice than some vintage applications even while retaining the same period construction style. It is a strong reference point for owners who want the correct basic fitment first, then want to choose the sidewall presentation that best suits the car.
Sub-model fitment matters on the 1967 Ford Thunderbird because the covered configurations do not all use the same tire size. Every application stays within the same 15-inch bias-ply family, but identifying the exact sub-model is still the key step before comparing appearance options or considering any equivalent route.

1967 Ford Thunderbird All Other Models
The 1967 Ford Thunderbird All Other Models grouping uses the larger numeric bias-ply fitments in this range, centered on 8.45-15 and 855-15. That makes this sub-model especially important to verify if the goal is choosing between traditional bias-ply presentation and the radial-equivalent alternatives associated with 855-15.
The 1967 Ford Thunderbird Tudor Non-Air uses the smaller numeric bias-ply fitments in this application range, including 8.25-15 and 815-15. Tire selection here is mainly about confirming the correct size first, then choosing among the available period-style sidewall treatments within that proper bias-ply format.
Bias-Ply to Radial Tire Conversion for the 1967 Ford Thunderbird
For the original 855-15 tire size, four radial-equivalent options are available. They include 215R15 as an 80-series metric radial, P225/75R15 as a 75-series P-metric radial, P235/70R15 as a 70-series P-metric radial, and 760R15 as a bias-look radial equivalent. These choices differ by sizing convention and profile family, with the bias-look radial aimed at a more traditional visual presentation. A 6-8 inch rim-width range is associated with these equivalents, and wheel compatibility, overall dimensions, and clearance should still be checked before conversion.

Best 1967 Ford Thunderbird Tires for Sale
Available 1967 Ford Thunderbird tire options center on BFGoodrich Silvertown Classic Bias Ply selections in 855-15 and 815-15. The main comparison points are sidewall treatment, including narrow whitewall and whitewall-redline styling, along with the rim-width and load specifications tied to each size.
Common 1967 Ford Thunderbird tire questions usually come down to identifying the right sub-model size, understanding the older numeric bias-ply format, and deciding whether to stay period-style or evaluate the 855-15 radial-equivalent options.
Tire Size & Fitment
What tire size fits a 1967 Ford Thunderbird?
A 1967 Ford Thunderbird can use 8.45-15, 855-15, 8.25-15, or 815-15, and all four are bias-ply sizes for 15-inch rims. The correct size depends on the specific sub-model, with All Other Models using 8.45-15 or 855-15 and Tudor Non-Air using 8.25-15 or 815-15.
That means the first job is identifying the car’s exact configuration before choosing a tire. Once the proper size is confirmed, the next decision is usually whether to stay with a traditional bias-ply presentation or, in the case of 855-15, look at a modern radial-equivalent alternative after checking wheel compatibility and clearance.
What size rim does a 1967 Ford Thunderbird use?
The 1967 Ford Thunderbird tire sizes covered here are all built for 15-inch rims. That applies across 8.45-15, 855-15, 8.25-15, and 815-15, so the wheel diameter remains consistent even though the tire width classes vary by sub-model.
Rim diameter is only part of the fitment picture on a vintage Thunderbird. Wheel width still matters, especially if the car has replacement wheels, and a tire conversion should never be chosen by diameter alone. Verifying the actual wheel dimensions on the car helps prevent mismatches when moving between available bias-ply options or considering a radial equivalent for 855-15.
Do all 1967 Ford Thunderbird sub-models use the same tire size?
No. The 1967 Ford Thunderbird uses different primary tire sizes depending on the sub-model. All Other Models use 8.45-15 or 855-15, while Tudor Non-Air uses 8.25-15 or 815-15, even though all of them remain within the same 15-inch bias-ply family.
That difference matters because vintage numeric sizes are not interchangeable just because they share the same wheel diameter. The buyer should confirm the exact sub-model first, then compare the actual tire options available in that size. This is especially important if the car has been modified over the years or if the goal is to preserve a restoration-oriented stance and appearance.
Bias-Ply & Radial Options
Is 855-15 a bias-ply or radial tire for the 1967 Ford Thunderbird?
For the 1967 Ford Thunderbird, 855-15 is a primary bias-ply tire size. It uses the older numeric bias-ply sizing system and belongs to the traditional 15-inch fitment family used on certain Thunderbird configurations that year.
That distinction matters because a radial equivalent and a bias-ply tire are not the same thing, even when they are considered comparable in size. Owners who want period-style construction and appearance will stay within the 855-15 bias-ply format, while anyone considering a radial alternative should also confirm wheel width, overall fit, and clearance before changing construction.
What radial tire sizes are equivalent to 855-15?
Radial equivalents for 855-15 include 215R15, P225/75R15, P235/70R15, and 760R15. Those cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial equivalent that keeps a more traditional visual character.
The practical difference is that these options follow different sizing conventions and may suit different goals for appearance and road use. A 6-8 inch rim-width range is associated with the equivalent fitment path, but diameter match alone is not enough. Clearance, wheel width, and the car’s actual setup should be checked before treating any one of these sizes as the right conversion.
What should I check before converting my 1967 Ford Thunderbird from bias-ply to radial tires?
A 1967 Ford Thunderbird owner considering a conversion should start by confirming the original tire size on the car, then match that size to the correct radial-equivalent path where one exists, such as the 855-15 equivalents. Wheel diameter, wheel width, and the specific tire size being considered all need to be part of that decision.
The next checks are practical vehicle-fitment items rather than just size labels. Inspect steering and fender clearance, look at suspension condition, and make sure the wheels are appropriate for the radial being considered. On an older car, it also helps to verify that previous wheel or ride-height changes have not altered the space available around the tire.
Choosing the Right Tire
What should I consider when choosing a 855-15 tire for a 1967 Ford Thunderbird?
Choosing a 855-15 tire for a 1967 Ford Thunderbird starts with confirming that the car falls within the sub-model group that uses that size. From there, the key factors are whether the goal is a traditional bias-ply tire, a particular sidewall presentation, or a move toward one of the radial-equivalent options tied to 855-15.
BFGoodrich Silvertown Classic Bias Ply choices in 855-15 focus on a narrow whitewall look, while the equivalent path expands the construction decision beyond bias-ply. Wheel width, intended driving style, and the visual character desired for the car should shape the final choice. A restoration-oriented Thunderbird often calls for different priorities than one being prepared for more regular road use.
What sidewall styles are available for 1967 Ford Thunderbird tires?
The available sidewall styles for 1967 Ford Thunderbird tires here include narrow whitewall and whitewall-redline treatments. Those appearance options are tied to specific sizes, with narrow whitewall offered in both 855-15 and 815-15, and whitewall-redline available in 815-15.
Sidewall style can change the car’s visual character significantly even when the size and construction stay the same. The best approach is to confirm the correct tire size first, then choose the sidewall treatment that suits the Thunderbird’s presentation. A buyer focused on a restrained luxury look may choose differently than someone leaning toward a more period-performance-inspired appearance.
What brands offer tires for the 1967 Ford Thunderbird?
BFGoodrich offers the available 1967 Ford Thunderbird tires in the product range shown here, specifically through the Silvertown Classic Bias Ply series. Those products cover 855-15 and 815-15 applications and focus on traditional bias-ply construction with vintage-style sidewall treatments.
That means brand comparison is less important here than size, construction, and sidewall choice. A buyer should first confirm whether the car uses 855-15 or 815-15, then compare the visual treatment and wheel-fit details attached to that exact size. For a vintage Thunderbird, choosing the correct fitment usually matters more than chasing unnecessary variation.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Ford Thunderbird?
A period-style 1967 Ford Thunderbird tire choice starts with the correct numeric bias-ply size for the car’s sub-model. That means staying within the original-style 15-inch bias-ply fitment family, such as 855-15 for certain cars or 815-15 for Tudor Non-Air, rather than choosing by appearance alone.
Once the proper size is confirmed, sidewall treatment becomes the main appearance decision. Narrow whitewall and whitewall-redline options create different presentations while keeping the vintage bias-ply format intact. When exact historical originality matters, it is wise to compare the tire choice against marque literature, restoration references, or other vehicle-specific documentation before settling on the final look.
How does tire construction affect the appearance of a restored 1967 Ford Thunderbird?
Tire construction influences both the stance and the visual character of a restored 1967 Ford Thunderbird. A bias-ply tire preserves the older sizing format and traditional presentation associated with the car’s original era, while a radial alternative can change the way the tire looks even when it serves as an equivalent size option.
That is why restoration-minded buyers often decide on construction before narrowing down sidewall style. An owner focused on period appearance may prefer to remain with the Thunderbird’s primary bias-ply fitment, while someone prioritizing road use may still want a radial that keeps a more traditional look. Either way, the visual effect should be weighed alongside proper fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Ford Thunderbird?
Yes. Modifications can affect tire fitment on a 1967 Ford Thunderbird even when the car still uses a 15-inch wheel. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs can all influence how a vintage-size tire sits and clears the car.
That is especially important when choosing among multiple primary sizes or considering a radial equivalent for 855-15. A Thunderbird that no longer has its original wheel and suspension relationship may need extra measurement before a tire is selected. Checking side clearance, steering travel, and visible fender space helps avoid choosing a size simply because it seems close on paper.
What should I inspect before driving a 1967 Ford Thunderbird on new tires?
Before driving a 1967 Ford Thunderbird on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware is appropriate, and make sure each tire is mounted in the proper size for the sub-model. It also helps to look over the suspension and steering components so the new tires are not being asked to compensate for worn chassis parts.
After installation, check inflation, look for any rubbing at full steering lock, and recheck the car after a short drive for unusual wear or air loss. On a collector car, it is smart to stay alert for issues that do not show up immediately, especially if the Thunderbird has spent long periods off the road before receiving fresh tires.
How should 855-15 tires on a collector 1967 Ford Thunderbird be maintained?
855-15 tires on a collector 1967 Ford Thunderbird should be maintained with regular pressure checks, visual inspections, and careful storage habits. Look for cracking, bulges, cuts, uneven wear, and signs of slow air loss, especially on a car that is driven infrequently and may sit for extended periods.
Storage conditions matter almost as much as mileage on an older collector vehicle. Keeping the Thunderbird away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition between drives. It is also a good idea to inspect the tires before any longer outing rather than assuming low annual mileage means they are automatically road ready.
