The 1955 Rolls Royce Phantom belongs to a rarefied postwar luxury tradition, built for formal coachwork, ceremonial use, and the kind of road presence that depends as much on stance as on craftsmanship. On a car of this character, tire choice is not a minor detail, because the tire helps define both appearance and the measured driving feel expected from a large mid-century Rolls-Royce. The 1955 Rolls Royce Phantom uses an 8.00-17 bias-ply tire on a 17-inch rim. That keeps the decision centered on selecting the right period-style bias-ply presentation rather than sorting through multiple primary fitments. For restoration, touring, or careful road use, wheel condition and overall tire age deserve as much attention as size.
Which Tire Size Is Right for The 1955 Rolls Royce Phantom
The 1955 Rolls Royce Phantom uses one primary tire size: 8.00-17. It is a bias-ply fitment for a 17-inch rim, and the covered Phantom IV sub-model uses that same size. That means the main decision is not choosing between multiple original sizes, but selecting an 8.00-17 tire that suits the car's appearance, restoration direction, and intended road use while confirming the actual wheel setup on the vehicle.
An 8.00-17 size uses the traditional numeric bias-ply system, where 8.00 refers to the nominal section width in inches and 17 identifies the wheel diameter. On a 1955 Rolls Royce Phantom, that sizing format matches the period character of a large formal luxury car that was designed around bias-ply construction. The practical focus with this size is preserving the proper visual proportion and traditional tire presentation expected on a mid-1950s Rolls-Royce. Before choosing an 8.00-17 tire, confirm that the wheels on the car are still 17-inch originals or correct replacements and inspect for age, condition, and clearance.
Tire fitment for the covered 1955 Rolls Royce Phantom sub-model is straightforward. The Phantom IV uses the same primary size, so the emphasis stays on selecting the right 8.00-17 bias-ply tire and confirming that the car still carries the proper 17-inch wheel setup.

Frequently Asked Questions
Tire questions for a 1955 Rolls Royce Phantom usually center on the 8.00-17 size, 17-inch wheel fitment, bias-ply construction, restoration-minded appearance, and the condition checks that matter before putting a seldom-driven collector car back on the road.
Tire Size & Fitment
What tire size fits a 1955 Rolls Royce Phantom?
The 1955 Rolls Royce Phantom uses an 8.00-17 tire. This is a bias-ply fitment sized for a 17-inch wheel, and it is the primary tire size associated with the covered vehicle.
That makes the first step fairly simple: confirm that the car still has 17-inch wheels and then focus on choosing the right 8.00-17 tire for the vehicle's condition and intended use. On a collector Rolls-Royce, actual wheel configuration matters because older cars may have had wheel replacements, long-term storage issues, or restoration changes over time.
What size rim does a 1955 Rolls Royce Phantom use?
The 1955 Rolls Royce Phantom uses a 17-inch rim with its 8.00-17 tire size. The tire size itself ends in 17, and the applicable wheel diameter for this fitment is 17 inches.
Rim diameter should be confirmed before any tire purchase, especially on a restored or seldom-driven luxury car. A tire may have the correct overall style for the period, but it still needs to match the wheel diameter actually on the car. Checking the wheel itself also helps catch issues such as damage, corrosion, or replacement wheels that do not match the original setup.
Does the 1955 Rolls Royce Phantom IV use the same tire size?
Yes. The 1955 Rolls Royce Phantom IV uses the same 8.00-17 bias-ply tire size as the covered 1955 Rolls Royce Phantom fitment. That keeps sub-model tire selection straightforward rather than splitting it across multiple original sizes.
Even with shared fitment, it is still worth checking the actual wheels and the car's restoration status before replacing tires. A vehicle in this class may have seen coachbuilt bodywork, long periods of storage, or wheel service over the years. Matching the tire size is essential, but so is confirming wheel condition, usable clearance, and the overall state of the running gear.
Choosing the Right Tire
What should I consider when choosing an 8.00-17 tire for a 1955 Rolls Royce Phantom?
Start with the correct primary size and construction. The 1955 Rolls Royce Phantom uses an 8.00-17 bias-ply tire, so the selection process should begin with maintaining that period-appropriate sizing system and confirming the 17-inch wheel diameter.
From there, the real considerations are the car's restoration direction, expected road use, and the condition of the wheels and suspension. A formal mid-century Rolls-Royce usually benefits from a tire that preserves the proper visual proportion and traditional presentation. Tire age, sidewall condition, and overall wheel integrity matter just as much as choosing the right size code.
How do I choose between the available 8.00-17 tires for a 1955 Rolls Royce Phantom?
The key is to compare tires within the correct 8.00-17 bias-ply size rather than looking for a different primary fitment. For this vehicle, the meaningful differences usually come down to how closely the tire suits the car's period look, the condition of the existing wheels, and the way the car will actually be driven.
A Phantom intended for judged display may call for a more restoration-oriented presentation, while a car used for occasional road exercise still needs the same careful sizing discipline with close attention to condition and compatibility. It is also wise to inspect wheel runout, valve hardware, and any signs of prior repairs before mounting fresh tires on an older collector chassis.
What rim-fitment details should I compare when choosing 1955 Rolls Royce Phantom tires?
The most important rim-fitment detail is wheel diameter, since the 1955 Rolls Royce Phantom uses an 8.00-17 tire on a 17-inch rim. Beyond diameter, the wheel itself should be appropriate for the tire and in sound condition, especially on a large, heavy luxury vehicle from the 1950s.
Wheel width, bead-seat condition, and overall wheel integrity all deserve attention before fitting new tires. Cars that have been restored or stored for long periods may also have rust, distortion, or old repairs that affect mounting and use. Verifying the actual wheel setup on the car helps avoid selecting a tire that is correct in size but mismatched to the wheel condition.
Restoration & Appearance
Which tire should I choose for a period-style 1955 Rolls Royce Phantom?
A period-style approach starts with the original-type sizing format and construction. For the 1955 Rolls Royce Phantom, that means an 8.00-17 bias-ply tire, which preserves the traditional proportions and visual character expected on a formal postwar Rolls-Royce.
That does not automatically make every tire in the size equally suitable for every restoration goal. Some owners prioritize authenticity of presentation, while others need a roadworthy tire for careful touring and event use. When exact originality matters, it is worth comparing the car against marque-specific references, historical photos, and restoration documentation before making a final appearance choice.
Does correct tire fitment matter for a 1955 Rolls Royce Phantom restoration?
Yes, correct tire fitment matters a great deal on a 1955 Rolls Royce Phantom. The tire size, construction type, and overall visual proportion all influence how the car sits, how the wheel openings are filled, and whether the finished restoration looks coherent with the vehicle's era.
Using the proper 8.00-17 bias-ply format helps preserve the car's period presentation, but restoration fitment is not only about appearance. Wheel condition, age-related deterioration, and the actual setup on the chassis also affect whether the car is ready for display or road use. A careful fitment check keeps the restoration from being undermined by avoidable tire or wheel mismatches.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1955 Rolls Royce Phantom?
Yes. Even though the primary fitment is straightforward at 8.00-17 on a 17-inch rim, modifications can still affect tire selection on a 1955 Rolls Royce Phantom. Replacement wheels, brake work, suspension changes, or body restoration can all alter the space and hardware around the tire.
A collector car should never be evaluated by size code alone if it has been changed over the years. Wheel diameter still needs to match, but clearance at the fender, steering components, and suspension should also be checked. Taking measurements from the actual vehicle helps avoid problems that may not be obvious until the tires are mounted and the car is moving.
What should I inspect before driving a 1955 Rolls Royce Phantom on new tires?
Inspect the wheels, valve hardware, and the overall condition of the suspension and steering before putting a 1955 Rolls Royce Phantom back on the road. New tires are only one part of the system, and an older luxury car can still have issues with wheel condition, alignment, or long-stored mechanical components.
A close look at clearances, fasteners, and signs of rubbing is worthwhile once the tires are mounted. Tire pressure should be monitored carefully during initial use, and the car should be driven gently enough to confirm that it tracks properly and shows no vibration or interference. Rechecking the tires after the first miles can catch developing issues early.
How should 8.00-17 tires on a collector 1955 Rolls Royce Phantom be maintained?
Collector-car tires should be maintained with regular pressure checks, visual inspections, and careful storage practices. On a 1955 Rolls Royce Phantom using 8.00-17 bias-ply tires, that means watching for cracking, bulges, cuts, uneven wear, and any signs of air loss even if the car is driven only occasionally.
Low annual mileage does not prevent tire aging, so time and storage conditions matter as much as tread depth. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help protect the tires while the vehicle is parked. It also helps to inspect the sidewalls and tread before every outing rather than assuming a stored tire is still road-ready.
