The 1967 American Motors Ambassador sat in AMC’s full-size family-car range at a time when comfort, presence, and traditional American road manners still defined the segment. Whether in 6 & 8 Cyl. form or as a Wagon, this is a car buyers often approach with an eye toward correct stance as much as road use. Tire fitment centers on four 14-inch bias-ply sizes: 735-14, 775-14, 825-14, and 855-14, with size choice tied to the specific body configuration. Available options range from blackwall and narrow whitewall styles to redline, goldline, and blueline treatments, and several modern radial equivalents can also be considered after wheel and clearance checks.
Which Tire Size Is Right for The 1967 American Motors Ambassador
The 1967 American Motors Ambassador uses four primary tire sizes, and the right one depends first on the exact sub-model. All of them are bias-ply tires for 14-inch rims, so the main fitment question is not wheel diameter but whether the car is a 6 & 8 Cyl. model or a Wagon. Once that is settled, the decision shifts to sidewall appearance, brand and tire-series preference, and whether a modern radial equivalent is worth evaluating.
In a numeric bias-ply size like 735-14, the 7.35 portion refers to the tire’s nominal section width in inches, while 14 identifies the wheel diameter. This is a traditional bias-ply fitment for the 1967 American Motors Ambassador, suited to buyers who want to stay with the vehicle’s period tire construction. Available choices in this size include BFGoodrich Silvertown Classic Bias Ply tires in blackwall and narrow whitewall versions. It is a useful size to evaluate when preserving a stock-style look matters, while still confirming the actual wheel setup on the car.
The 775-14 size follows the same vintage numeric bias-ply system, with a nominal 7.75-inch section width and a 14-inch rim diameter. On a 1967 American Motors Ambassador, it represents a traditional bias-ply fitment with the broadest range of appearance choices among the available products. BFGoodrich, Firestone, and US Royal offerings appear in several classic series and sidewall treatments, including narrow whitewall, redline, goldline, and blueline. This size deserves extra attention when appearance is a major part of the decision, especially on a restoration-oriented car.
An 825-14 is another numeric bias-ply size, indicating an approximate 8.25-inch nominal section width for a 14-inch wheel. For the 1967 American Motors Ambassador, this is one of the larger primary bias-ply fitments and is associated with the Wagon range rather than every configuration. Product choices in this size come from BFGoodrich’s Silvertown Classic Bias Ply line in blackwall and narrow whitewall forms. It is the right size to consider when matching the Wagon’s original-style tire format while choosing between a plainer or more dressy sidewall presentation.
The 855-14 code denotes a numeric bias-ply tire with an approximate 8.55-inch nominal section width on a 14-inch rim. This is the largest primary size used within the 1967 American Motors Ambassador range and appears on Wagon applications rather than across the full model line. Available products are BFGoodrich Silvertown Classic Bias Ply tires with narrow whitewall styling in different whitewall widths. This size is worth close comparison when the goal is to keep the fuller, traditional look associated with larger Ambassador Wagon fitments.
Sub-model fitment matters on the 1967 American Motors Ambassador because the covered configurations do not all use the same tire sizes. The first step is confirming whether the car is a 6 & 8 Cyl. model or a Wagon, since that determines which of the four 14-inch bias-ply sizes belongs on it.

1967 American Motors Ambassador 6 & 8 Cyl.
The 1967 American Motors Ambassador 6 & 8 Cyl. uses the smaller pair of primary bias-ply sizes within the model range, both on 14-inch rims. That means tire selection is centered on choosing the correct size first, then narrowing by sidewall style, tire series, or a radial-equivalent path if a construction change is under consideration.
The 1967 American Motors Ambassador Wagon uses the larger pair of primary bias-ply sizes in this lineup, also on 14-inch rims. That makes the Wagon its own fitment case, so owners should confirm the exact wheel setup before comparing blackwall or whitewall bias-ply options or reviewing radial equivalents.
Bias-Ply to Radial Tire Conversion for the 1967 American Motors Ambassador
Each primary tire size for the 1967 American Motors Ambassador has radial-equivalent choices to compare. For 735-14, the options are 185R14 as an 80-series metric radial, P195/75R14 as a 75-series P-metric radial, and P205/70R14 as a 70-series P-metric radial. For 775-14, 825-14, and 855-14, the equivalents progress similarly, with 750R14 and 800R14 serving as bias-look radial options for 775-14 and 825-14. Recommended rim-width ranges run from 4-6 inches or 5-7 inches depending on size, so wheel width, overall dimensions, and clearance should all be checked before converting.

These FAQs focus on the real tire decisions for a 1967 American Motors Ambassador, including sub-model sizing, 14-inch rim fitment, bias-ply versus radial choices, appearance options, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 1967 American Motors Ambassador?
The 1967 American Motors Ambassador uses four primary tire sizes: 735-14, 775-14, 825-14, and 855-14. The 6 & 8 Cyl. models use 735-14 or 775-14, while the Wagon uses 825-14 or 855-14, so there is not one universal size across the full Ambassador range.
The key step is matching the tire to the exact sub-model and the actual wheel setup on the car. Since all four sizes are bias-ply fitments for 14-inch rims, the main variables are the specific Ambassador configuration, the tire’s overall presentation, and whether the car still carries stock-type wheels or has been altered over time.
What size rim does a 1967 American Motors Ambassador use?
The primary tire fitments for the 1967 American Motors Ambassador all use a 14-inch rim diameter. That remains true across 735-14, 775-14, 825-14, and 855-14, so the wheel diameter is consistent even though the tire sizes vary by sub-model.
Rim diameter is only one part of the fitment picture, especially on a collector car that may have seen wheel changes over the years. It is still worth confirming actual wheel width and checking the tire’s approved rim-width range before choosing among bias-ply options or considering a modern radial equivalent.
Do all 1967 American Motors Ambassador sub-models use the same tire size?
No. The 1967 American Motors Ambassador 6 & 8 Cyl. and the 1967 American Motors Ambassador Wagon do not share the same tire-size set. The 6 & 8 Cyl. models use 735-14 or 775-14, while the Wagon uses 825-14 or 855-14.
That difference matters because the larger Wagon sizes change the pool of available tires and radial equivalents you can compare. Before selecting a tire, confirm the exact sub-model and then verify the current wheel dimensions, especially if the car has had replacement wheels, suspension work, or other changes that could affect practical fitment.
Bias-Ply & Radial Options
Is 775-14 a bias-ply or radial tire for the 1967 American Motors Ambassador?
On the 1967 American Motors Ambassador, 775-14 is a primary bias-ply tire size. It uses the vintage numeric sizing system, and the available tires in this fitment are bias-ply products rather than radial primary fitments.
That makes 775-14 the right starting point for owners who want the traditional construction and look associated with the car’s original era. A radial can still be considered through an equivalent size, but wheel width, overall dimensions, and clearance should be reviewed carefully rather than assuming any radial option will behave like a direct substitute.
What radial tire sizes are equivalent to 775-14?
Radial equivalents for 775-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, and P215/70R14 as a 70-series P-metric radial. A 750R14 bias-look radial is also available as an equivalent option for buyers who want a more traditional visual presentation.
Those choices give different sizing formats and profile conventions while staying in the same comparison family. The recommended rim-width range for these equivalents is 4 to 6 inches, and it is smart to check wheel width, fender clearance, and suspension condition before moving from the original-style bias-ply fitment to any radial alternative.
What should I check before converting my 1967 American Motors Ambassador from bias-ply to radial tires?
Start by confirming the original bias-ply size used on the specific Ambassador sub-model, then compare only the radial equivalents tied to that size. Wheel diameter, approved rim-width range, and the available equivalent formats all matter, whether the choice is an 80-series metric radial, a P-metric radial, or a bias-look radial where offered.
A conversion should also account for the car’s actual condition and setup. Check for adequate clearance during steering and suspension travel, inspect wheel width and condition, and make sure no previous modifications have changed the fitment envelope. That approach keeps the decision focused on compatibility rather than on the size label alone.
Choosing the Right Tire
What should I consider when choosing a 775-14 tire for a 1967 American Motors Ambassador?
A 775-14 tire choice starts with making sure that size belongs on the specific 1967 American Motors Ambassador configuration and wheel setup. From there, the main selection factors are bias-ply construction, sidewall appearance, brand, tire series, approved rim-width range, and any load-capacity differences that matter for how the car is used.
Within 775-14, the buyer has more visual variety than in some of the other Ambassador sizes. Narrow whitewall, redline, goldline, and blueline treatments are all available, so the final decision often comes down to whether the car is being kept plain, dressed for a period-style restoration, or balanced between traditional appearance and personal preference.
What sidewall styles are available for 1967 American Motors Ambassador tires?
Sidewall choices for the 1967 American Motors Ambassador include blackwall, narrow whitewall, redline, goldline, and blueline, depending on the tire size. The broadest assortment appears in 775-14, while the other sizes are offered in a narrower mix, especially blackwall and narrow whitewall combinations.
That means sidewall style is not just an appearance choice; it can also narrow the correct size and product options. Once the right Ambassador sub-model and tire size are confirmed, compare the available sidewall treatments in that exact size rather than assuming the same visual options carry across all four fitments.
What brands offer tires for the 1967 American Motors Ambassador?
BFGoodrich, Firestone, and US Royal all appear in the available tire range for the 1967 American Motors Ambassador, although not every brand is offered in every size. BFGoodrich covers all four primary sizes, while Firestone and US Royal are present in the 775-14 portion of the fitment range.
Brand choice should be weighed alongside size, tire series, and sidewall style rather than treated as a separate decision. Some Ambassador owners will be focused on a certain visual treatment, while others will simply want the correct bias-ply fitment in a traditional blackwall or narrow whitewall, so compare the exact size-specific offerings first.
Restoration & Appearance
Which tire should I choose for a period-style 1967 American Motors Ambassador?
A period-style 1967 American Motors Ambassador starts with the correct primary bias-ply size for the exact sub-model. For 6 & 8 Cyl. cars that means choosing between the applicable 735-14 or 775-14 fitment, while Wagons center on 825-14 or 855-14, all in traditional 14-inch bias-ply form.
After size is settled, the visual decision becomes sidewall treatment and series selection. Blackwall gives a simpler presentation, while narrow whitewall, redline, goldline, or blueline can shift the car’s character noticeably. If exact originality matters, compare the finished look against marque references and period photos rather than relying only on general era style.
How does tire construction affect the appearance of a restored 1967 American Motors Ambassador?
Tire construction changes the look of a restored 1967 American Motors Ambassador in ways enthusiasts notice quickly. The car’s primary fitments are bias-ply sizes, so staying with bias-ply construction helps preserve the traditional profile and visual character associated with a mid-1960s full-size American car.
A radial equivalent can still be a reasonable choice, but it may present the car differently even when the tire remains in the same general fitment family. Owners balancing restoration appearance with road use often compare the original-style bias-ply option first, then evaluate whether a radial alternative changes the stance or sidewall impression more than desired.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 American Motors Ambassador?
Yes. A 1967 American Motors Ambassador may have the correct nominal tire size on paper and still run into fitment issues if the wheels, ride height, suspension, or body clearances have changed. That is especially important on a car with multiple primary sizes tied to different sub-models.
Aftermarket wheels can alter width and positioning even when the rim diameter remains 14 inches. Suspension work, lowering, or worn components can also change clearance during turns and full travel. Before choosing a replacement tire or radial equivalent, inspect the actual wheel setup and check for rubbing at the fender, frame, and steering components.
What should I inspect before driving a 1967 American Motors Ambassador on new tires?
Before putting a 1967 American Motors Ambassador back on the road, inspect wheel condition, lug hardware, valve stems, and general suspension condition along with the new tires themselves. The tires should be checked for proper inflation, even tread seating, and any signs that the selected size is too close to body or steering components.
A short, careful road test is a smart follow-up, especially on a collector car that may not be driven often. Listen for rubbing, confirm the steering returns smoothly, and watch for vibration or pull that could point to alignment or wheel issues. Those checks matter whether the car stays on bias-ply tires or moves to a radial equivalent.
How should 775-14 tires on a collector 1967 American Motors Ambassador be maintained?
Collector-car tires such as 775-14 fitments on a 1967 American Motors Ambassador should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Look for cracking, bulges, cuts, flat spotting from long storage, and slow air loss, even if the tread still appears strong.
Storage habits matter almost as much as mileage on a low-use car. Keep the Ambassador away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or compressors. A periodic inspection schedule and occasional exercise of the car can help catch condition changes before they become a road-use problem.
