The 1956 Rolls Royce Phantom belongs to a very exclusive postwar British luxury tradition, where formal coachbuilt presentation mattered as much as quiet road manners. Vehicles in this class are often approached as preservation pieces as much as transportation, so tire choice affects stance, authenticity of appearance, and confidence on limited road use. The 1956 Rolls Royce Phantom uses an 8.00-17 bias-ply tire on a 17-inch rim. That keeps the decision focused on selecting the right period-style construction and presentation within the correct size. For a restoration-oriented owner, matching the proper fitment and carefully verifying wheel condition before road service are just as important as tread choice.
Which Tire Size Is Right for The 1956 Rolls Royce Phantom
The 1956 Rolls Royce Phantom uses one primary tire size: 8.00-17. It is a bias-ply fitment on a 17-inch rim, and the covered Phantom IV application uses that same size, so the main decision is not choosing between multiple fitments but selecting the right period-style tire within the proper size and construction.
An 8.00-17 size is a numeric bias-ply designation in which 8.00 refers to the nominal section width in inches and 17 identifies the wheel diameter. For a 1956 Rolls Royce Phantom, that sizing points to a traditional bias-ply construction suited to the vehicle’s formal mid-century character and original-era tire profile. Buyers looking at this size are usually balancing correct visual proportion, appropriate rim compatibility, and the kind of road use the car will actually see. It is the right size to evaluate when the goal is to preserve the Phantom’s traditional presentation rather than modernize the overall look.
Fitment is straightforward for the covered 1956 Rolls Royce Phantom sub-model. The Phantom IV uses the same primary tire size, so sub-model identification is mainly a confirmation step before choosing the right bias-ply tire and checking the car’s existing wheel setup.

1956 Rolls Royce Phantom IV
The 1956 Rolls Royce Phantom IV uses the same 8.00-17 bias-ply fitment as the core vehicle application. That keeps the choice centered on selecting an appropriate period-style tire in the correct size and confirming that the rims and overall chassis setup still match the original-style specification.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Owners of a 1956 Rolls Royce Phantom usually have questions about the 8.00-17 tire size, 17-inch rim fitment, bias-ply construction, restoration appearance, and the checks that matter before putting a rarely driven collector car back on the road.
Tire Size & Fitment
What tire size fits a 1956 Rolls Royce Phantom?
The 1956 Rolls Royce Phantom uses an 8.00-17 tire size. That is a traditional numeric bias-ply size and it fits a 17-inch rim, which aligns with the formal, period-correct style expected on a large coachbuilt luxury car of this era.
The practical step is confirming that the car still has the proper 17-inch wheels and has not been changed to a different rim diameter during earlier restoration or service work. On a collector vehicle, wheel condition, tire age, and overall clearance should be checked before road use, even when the size code itself is correct.
What size rim does a 1956 Rolls Royce Phantom use?
The 1956 Rolls Royce Phantom uses a 17-inch rim with its 8.00-17 tire fitment. The rim diameter is the last number in the tire size, so the tire and wheel must both match that 17-inch specification.
Measuring the wheel before ordering tires is worthwhile, especially on a hand-built or restored vehicle where wheels may have been changed decades ago. The diameter must match the tire, but condition matters too, so inspect the rims for corrosion, damage, bead-seat issues, and any signs that long-term storage may have affected safe tire mounting.
Does the 1956 Rolls Royce Phantom IV use the same tire size?
Yes. The 1956 Rolls Royce Phantom IV uses the same 8.00-17 bias-ply tire size as the covered 1956 Rolls Royce Phantom application. That means the sub-model does not introduce a different primary size or a different rim diameter within this fitment range.
That consistency simplifies the search, but it does not remove the need to verify the actual wheels on the car. Collector vehicles can accumulate older replacement rims, mixed tires, or long-standing restoration choices, so checking the mounted wheel diameter and the overall condition of the existing setup remains an important final step.
Choosing the Right Tire
What should I consider when choosing a 8.00-17 tire for a 1956 Rolls Royce Phantom?
Start with the correct size and construction. For a 1956 Rolls Royce Phantom, that means an 8.00-17 bias-ply tire on a 17-inch rim, which preserves the traditional proportions and presentation associated with a formal luxury vehicle of the mid-1950s.
After confirming fitment, the real choice is how closely the tire should support the car’s restoration goals and intended use. A Phantom kept for shows or preservation may call for a strongly period-style appearance, while a car used for occasional touring still needs careful attention to wheel condition, tire age, and overall road readiness.
How do I choose between the available 8.00-17 tires for a 1956 Rolls Royce Phantom?
The first filter is always size and construction, since the 1956 Rolls Royce Phantom uses an 8.00-17 bias-ply fitment. Within that size, the most useful comparison points are overall appearance, how well the tire suits a restoration-oriented build, and whether the vehicle is mainly shown, preserved, or driven occasionally.
A large formal car places extra importance on visual proportion, so the tire should look appropriate on the wheel and complement the body’s stance. It also helps to consider the age and condition of the car’s suspension, steering, and wheels, since a carefully chosen tire still depends on a sound mechanical foundation.
What rim-fitment details matter when choosing tires for a 1956 Rolls Royce Phantom?
The key rim-fitment detail is matching the 8.00-17 tire to the correct 17-inch wheel diameter used on the 1956 Rolls Royce Phantom. Beyond diameter, the wheel itself should be structurally sound and appropriate for the tire being mounted.
Older collector cars deserve a closer look at wheel condition before any new tire goes on. Check for rust, bent flanges, previous repairs, and anything that could affect bead seating or balance. A car that has been off the road for long periods may also need its wheels cleaned and inspected before regular driving resumes.
Restoration & Appearance
Which tire should I choose for a period-style 1956 Rolls Royce Phantom?
A period-style 1956 Rolls Royce Phantom should start with the correct 8.00-17 size and a bias-ply construction. That combination maintains the visual character expected of a large mid-century Rolls-Royce and keeps the tire profile aligned with the car’s original-era stance and formal presence.
Appearance matters more on a vehicle like this than on many ordinary collector cars, because the tire is part of the overall coachbuilt impression. Buyers pursuing exact historical authenticity should compare the tire’s presentation with marque literature, restoration records, and club guidance rather than assuming every correct-size tire reflects the same original specification.
Does correct tire fitment matter for a 1956 Rolls Royce Phantom restoration?
Yes, correct tire fitment matters a great deal on a 1956 Rolls Royce Phantom restoration. Using the proper 8.00-17 bias-ply size helps preserve the car’s proportions, wheel-to-body relationship, and the restrained visual balance that defines a formal luxury car from this period.
Tire choice also affects how believable the finished restoration looks when viewed as a complete car rather than as an isolated component. Even if the vehicle is driven sparingly, the right size and construction support both presentation and function, while incorrect diameter or profile can change the stance enough to look visibly out of character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1956 Rolls Royce Phantom?
Yes. Modifications can affect tire fitment on a 1956 Rolls Royce Phantom, even when the intended tire size remains 8.00-17. Wheel changes, brake conversions, suspension work, or earlier restoration decisions can alter the actual space available around the tire and the way it sits on the car.
A Phantom that has aftermarket wheels or altered suspension should be checked carefully before any tire decision is finalized. Verify wheel diameter, wheel condition, and clearance at full steering lock and normal ride height. On a low-use collector car, it is also wise to inspect for uneven settling or age-related suspension changes.
What should I inspect before driving a 1956 Rolls Royce Phantom on new tires?
Before driving a 1956 Rolls Royce Phantom on new tires, inspect the wheels, valve hardware, and the general condition of the suspension and steering components. The tires themselves should also be checked after mounting for proper seating, stable air retention, and any visible issues before the car is put back into service.
A long-stored collector car deserves extra attention beyond the tires alone. Look for cracked rubber components, worn shocks, brake concerns, and anything that could affect how the car tracks or stops. A careful road-readiness check matters because even the correct 8.00-17 fitment cannot compensate for neglected chassis or wheel problems.
How should 8.00-17 tires on a collector 1956 Rolls Royce Phantom be maintained?
8.00-17 tires on a collector 1956 Rolls Royce Phantom should be maintained with regular pressure checks, visual inspections, and careful storage habits. Because collector cars may sit for extended periods, sidewall condition, tread integrity, and any signs of air loss deserve attention even when the car sees very few miles.
Storage environment has a real effect on tire life, especially on vehicles preserved more than they are driven. Keep the car away from prolonged sunlight, excessive heat, moisture, and ozone sources, and inspect the tires before each outing. An older luxury car should never be assumed road-ready simply because the tread still looks good.
