The 1939 Chrysler Royal belongs to a late prewar Chrysler era when streamlined styling, full-size comfort, and smooth six-cylinder touring manners shaped the ownership experience. Buyers drawn to one today are often balancing preservation, dependable road use, and the right visual stance. For this exact car, the primary tire fitment is a 6.25-16 bias-ply size, which keeps the vehicle in the sizing language and construction style of its period. The decision is less about sorting through multiple fitments and more about choosing the right period-style tire presentation within that size. That makes wheel confirmation, restoration goals, and real-world driving plans the key factors before moving forward.
Which Tire Size Is Right for The 1939 Chrysler Royal
The 1939 Chrysler Royal uses one primary tire size: 6.25-16. That is a bias-ply fitment for a 16-inch rim, and it carries through to the covered 6 Cyl. sub-model as well. Since the size itself is straightforward, the real choice becomes staying with the traditional bias-ply construction and selecting the tire that best suits the car's appearance, wheel setup, and intended road use.
In a numeric bias-ply size like 6.25-16, the 6.25 refers to the nominal section width in inches and the 16 identifies the rim diameter. This format is part of the traditional sizing system used on many prewar American cars, making it appropriate for the 1939 Chrysler Royal's original-era tire profile and look. Bias-ply construction also plays a major role in how the car presents visually, especially on a restoration-minded vehicle with stock-style wheels. Choosing this size starts with confirming the 16-inch wheel and then selecting a tire that matches the car's intended balance of authenticity, appearance, and use.
Tire fitment is straightforward across the covered 1939 Chrysler Royal sub-models. The key point is simply confirming that the car is the Royal 6 Cyl. configuration and still uses the expected 16-inch wheel before selecting a 6.25-16 tire.

Frequently Asked Questions
These 1939 Chrysler Royal tire FAQs focus on the 6.25-16 fitment, 16-inch rim compatibility, period-style bias-ply selection, restoration appearance, and the checks that matter before putting a prewar Chrysler back on the road.
Tire Size & Fitment
What tire size fits a 1939 Chrysler Royal?
The 1939 Chrysler Royal uses a 6.25-16 tire size. This is a numeric bias-ply fitment and it is the primary size associated with the model, including the covered Royal 6 Cyl. configuration.
That makes the first step fairly simple: confirm that the car still has the expected 16-inch wheels and has not been changed to a different wheel setup over the years. Once the wheel size is verified, the main decision becomes choosing a 6.25-16 tire that suits the car's intended appearance and driving use.
What size rim does a 1939 Chrysler Royal use?
The tire fitment for the 1939 Chrysler Royal is built around a 16-inch rim. The 6.25-16 size uses that 16-inch wheel diameter as the mounting point.
Wheel diameter matters just as much as tire size wording, especially on a prewar car that may have seen wheel changes during restoration or long-term ownership. A buyer should verify the actual wheel on the car before purchasing tires, because a tire sized for a 16-inch rim cannot be mounted correctly on a different wheel diameter.
Does the 1939 Chrysler Royal 6 Cyl. use the same tire size?
Yes. The covered 1939 Chrysler Royal 6 Cyl. uses the same 6.25-16 bias-ply tire size as the model's primary fitment. There is no alternate primary size shown for that sub-model.
That consistency simplifies the fitment search, but it is still worth checking the actual wheels on the car before ordering replacement tires. Many older cars have gone through decades of repairs and restorations, so confirming the wheel diameter and overall condition of the wheels is a smart step even when the original-size fitment is straightforward.
Choosing the Right Tire
What should I consider when choosing a 6.25-16 tire for a 1939 Chrysler Royal?
Start with the fundamentals: the 1939 Chrysler Royal uses a 6.25-16 bias-ply tire on a 16-inch rim. That means the first priority is selecting the correct period-style size and construction rather than substituting a modern-looking fitment without checking the rest of the setup.
After size confirmation, think about how the car will be used and presented. A preservation-minded sedan driven to shows may call for a different visual emphasis than a Chrysler that sees regular touring. Wheel condition, steering clearance, suspension health, and the overall look you want from the finished car should all guide the final choice.
How do I choose between available 6.25-16 tires for a 1939 Chrysler Royal?
Selection within 6.25-16 usually comes down to appearance, construction style, and how closely the tire suits the character of a late-1930s Chrysler. Since the primary fitment is already established, the comparison is less about finding a size and more about picking the right version of that size.
Look closely at how the tire complements the car's restoration direction and intended use. A formal sedan with stock-style wheels often benefits from a traditional presentation, while a more road-driven car may put added emphasis on general service readiness. Confirming wheel diameter and checking for any previous modifications should remain part of the decision.
Why does choosing the correct 6.25-16 fitment matter on a 1939 Chrysler Royal?
Using the correct 6.25-16 fitment matters because tire size affects how a 1939 Chrysler Royal sits, looks, and operates on its intended 16-inch wheels. On a prewar car, the wrong size can also change the overall visual balance in a way that stands out immediately.
Correct fitment also helps avoid practical mounting and clearance issues. Even when a car appears stock, it is wise to inspect the wheels, suspension condition, and space around the fenders before replacing old tires. Matching the car to its proper-size tire is one of the simplest ways to keep restoration character and road manners aligned.
Restoration & Appearance
Which tire should I choose for a period-style 1939 Chrysler Royal?
A period-style starting point for the 1939 Chrysler Royal is the original-format 6.25-16 bias-ply tire size. That keeps the car in the same general sizing system and construction type associated with its prewar design and helps preserve the tall, traditional tire presentation these cars are known for.
For many restorations, appearance is just as important as fitment. The exact brand or sidewall treatment should be matched to the level of historical accuracy you want, especially on a detail-focused build. Owners pursuing strict originality should compare tire choices with marque references, restoration photos, and other Chrysler-specific historical material.
Does correct tire fitment matter for a 1939 Chrysler Royal restoration?
Yes, correct tire fitment plays an important role in a 1939 Chrysler Royal restoration. The proper 6.25-16 bias-ply size supports the car's intended prewar stance and helps the finished vehicle look appropriate for its body proportions and wheel openings.
Fitment also affects how convincingly the restoration comes together as a whole. Wheels, hubcaps, ride height, and tire profile all work together visually on a full-size Chrysler of this era. Even on a driver-level restoration, checking the actual wheel size and avoiding mismatched modern substitutes can make a noticeable difference in the final result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1939 Chrysler Royal?
Yes. Even though the primary fitment is 6.25-16 on a 16-inch rim, modifications can change what needs to be checked on a 1939 Chrysler Royal. Wheel swaps, altered ride height, brake changes, or suspension work can all affect clearance and overall compatibility.
A car that appears original may still have different wheels or chassis parts than it left with decades ago. Measuring the actual wheel diameter, checking wheel width, and inspecting space at the fenders and steering components can prevent expensive mistakes. Those checks matter most before mounting new tires on any long-restored or newly acquired car.
What should I inspect before driving a 1939 Chrysler Royal on new tires?
Before putting a 1939 Chrysler Royal back into service on new tires, inspect the wheels, valve hardware, and general suspension and steering condition. Tire replacement is also a good time to check for cracked wheels, loose hardware, uneven wear patterns, and any signs that the previous tires were contacting surrounding components.
A prewar car often spends long periods parked, so road-readiness goes beyond tread depth alone. Check inflation, confirm that the tires seat properly on the 16-inch rims, and inspect for clearance through steering travel. A cautious test drive at low speed is a sensible way to confirm that the car feels settled before longer use.
How should 6.25-16 tires on a collector 1939 Chrysler Royal be maintained?
Collector-car tires in 6.25-16 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. On a 1939 Chrysler Royal that may not be driven often, sidewall cracking, flat spotting, air loss, and age-related deterioration can become more important than tread wear.
A good routine is to inspect the tires before each drive and again after long storage periods. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources can help protect the rubber over time. It also helps to move the vehicle periodically so the tires are not left carrying weight in one position for months.
