The 1947 Nash Ambassador 60 arrived in the immediate postwar market, when American buyers wanted comfort, modern styling, and dependable road manners from a full-size family car. Nash built a strong reputation in that era for practical engineering and distinctive design, which makes surviving Ambassador 60 models especially appealing to restorers and preservation-minded owners today. Tire fitment stays straightforward here, with a single 6.50-15 bias-ply size on a 15-inch rim. That keeps the main decision centered on choosing a period-style tire that suits the car’s look and intended use. Before putting the car back on the road, it is worth confirming wheel condition, overall tire age, and the rest of the chassis setup.
Which Tire Size Is Right for The 1947 Nash Ambassador 60
The 1947 Nash Ambassador 60 uses one primary tire size: 6.50-15 in bias-ply construction on a 15-inch rim. The covered 6 Cyl. sub-model uses that same fitment, so the question is less about choosing between sizes and more about selecting the right period-style tire within that size and confirming the wheel and vehicle setup before installation.
6.50-15 is a numeric bias-ply size, with the 6.50 referring to the tire’s nominal section width in inches and the 15 indicating the wheel diameter. On the 1947 Nash Ambassador 60, this is the primary bias-ply fitment and it matches the car’s postwar tire-sizing era and overall presentation. Buyers looking in this size are usually focused on maintaining a traditional side profile and road-going character that suits a restoration-oriented vehicle. The key is selecting a 6.50-15 that matches the car’s intended use while also confirming wheel condition, overall dimensions, and clearance on the actual vehicle.
Tire fitment is simple across the covered 1947 Nash Ambassador 60 sub-models. The 6 Cyl. version uses the same primary size, so the focus stays on choosing the right 6.50-15 bias-ply tire and verifying the condition of the car’s wheels and chassis.

Frequently Asked Questions
Common questions for the 1947 Nash Ambassador 60 usually center on its 6.50-15 fitment, 15-inch rim compatibility, period-style tire selection, and the checks that matter before returning a postwar collector car to regular road use.
Tire Size & Fitment
What tire size fits a 1947 Nash Ambassador 60?
The 1947 Nash Ambassador 60 uses a 6.50-15 tire in bias-ply construction. That is the primary fitment for this vehicle, and the covered 6 Cyl. sub-model uses the same size.
That makes size selection fairly straightforward, but the right choice still depends on the actual wheel and vehicle setup. A collector car may have replacement wheels, older service parts, or long-stored components, so it is smart to confirm the wheel diameter, inspect the rim, and check for adequate clearance before putting fresh tires into service.
What size rim does a 1947 Nash Ambassador 60 use?
The 1947 Nash Ambassador 60 uses a 15-inch rim with its 6.50-15 tire size. The 15 in the size code refers to the wheel diameter, which is the critical measurement for matching tire to rim.
Wheel diameter should be confirmed before ordering tires, especially on an older car that may have seen wheel changes over the years. It also helps to inspect the rim for damage, corrosion, or bead-seat issues, since vintage wheels can look usable while still needing attention before they are paired with new tires.
What does 6.50-15 mean on a 1947 Nash Ambassador 60?
On the 1947 Nash Ambassador 60, 6.50-15 is a numeric bias-ply tire size. The 6.50 refers to the tire’s nominal section width in inches, while 15 indicates the wheel diameter in inches.
This older sizing format is common on postwar American cars and differs from modern metric radial sizing. Understanding that format helps when comparing period-style replacements, because the goal is not just matching the printed size but also confirming that the tire works with the car’s wheel dimensions, body clearance, and intended driving use.
Choosing the Right Tire
What should I consider when choosing a 6.50-15 tire for a 1947 Nash Ambassador 60?
Start with the correct primary size, which is 6.50-15 in bias-ply construction for the 1947 Nash Ambassador 60. For many owners, the choice is about keeping a traditional postwar appearance and staying with a tire that suits the character of the car.
Beyond size, look closely at the condition and dimensions of the wheels already on the car, along with how the vehicle will actually be used. A lightly driven restoration, a preserved survivor, and a car that sees more regular road miles may lead buyers to weigh appearance, ride expectations, and general service readiness a little differently.
How do I choose between the available 6.50-15 tires for a 1947 Nash Ambassador 60?
The best way to compare 6.50-15 tires for a 1947 Nash Ambassador 60 is to keep the fitment fixed and then evaluate the tire’s overall presentation and intended use. Since the size itself is straightforward, the differences usually come down to how closely the tire matches the look and purpose you want.
A restoration-oriented car may call for a more traditional visual style, while a car built mainly for occasional touring may place more emphasis on general road readiness and service condition. Wheel integrity, proper mounting, and basic clearance checks matter just as much as the tire choice itself on a vehicle of this age.
What rim-fitment details should I compare when choosing 1947 Nash Ambassador 60 tires?
The most important rim-fitment detail on a 1947 Nash Ambassador 60 is the 15-inch wheel diameter required by the 6.50-15 tire size. Diameter must match exactly, since the tire cannot be used correctly on the wrong wheel size.
It also helps to inspect the actual wheel for age-related issues such as rust, dents, or damage around the bead area. Even when the wheel diameter is correct, a vintage car can still have service-replacement parts or wear that affects mounting quality, air retention, or overall confidence once the car returns to road use.
Restoration & Appearance
Which tire should I choose for a period-style 1947 Nash Ambassador 60?
A period-style starting point for the 1947 Nash Ambassador 60 is the original fitment type and size relationship: a 6.50-15 bias-ply tire on a 15-inch rim. That preserves the sizing format and construction style associated with the car’s immediate postwar character.
Owners restoring for visual authenticity often place a high value on that traditional bias-ply profile and stance. When exact originality matters beyond size and construction, it is wise to compare the car against marque literature, restoration references, or other reliable historical sources before settling on a final tire appearance.
Does correct tire fitment matter for a 1947 Nash Ambassador 60 restoration?
Correct tire fitment matters a great deal on a 1947 Nash Ambassador 60 because tire size and construction strongly influence the car’s stance, proportions, and overall presentation. Using the proper 6.50-15 bias-ply format keeps the vehicle visually aligned with its era.
Fitment also affects practical concerns such as wheel compatibility and body clearance, which become especially important on a freshly restored car. A well-finished restoration can be undercut by tires that look out of scale or do not suit the wheel properly, so appearance and fit should be considered together rather than separately.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1947 Nash Ambassador 60?
Yes, modifications can affect tire fitment on a 1947 Nash Ambassador 60 even when the intended tire size remains 6.50-15. Changes to wheels, suspension height, steering components, or brake hardware can alter the space available for a tire and how it sits on the car.
That is why the actual vehicle should be checked before installation, especially if the car has been restored, updated, or assembled from long-stored parts. Wheel diameter and condition are the first steps, followed by steering clearance, fender clearance, and a careful look at any changes that might influence tire placement.
What should I inspect before driving a 1947 Nash Ambassador 60 on new tires?
Before driving a 1947 Nash Ambassador 60 on new tires, inspect the wheels for corrosion, dents, cracks, and bead-seat problems, then confirm that the tires are mounted correctly and inflated appropriately for service. A quick visual check of the suspension and steering components is also worthwhile.
Road readiness on a collector car involves more than fresh rubber. Look for rubbing at full steering lock, signs of uneven stance, and any issues with air loss after mounting. A short, cautious initial drive helps reveal vibration, pull, or clearance concerns before the car is asked to handle longer distances.
How should 6.50-15 tires on a collector 1947 Nash Ambassador 60 be maintained?
6.50-15 tires on a collector 1947 Nash Ambassador 60 should be maintained with regular pressure checks, routine visual inspection, and close attention to aging. Because collector cars often sit for extended periods, sidewall cracking, flat spotting, and slow air loss deserve as much attention as tread wear.
Storage conditions matter, too. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition over time. It is also smart to inspect the tires before every meaningful outing, since a car that is driven only occasionally can still develop age-related tire issues.
