The 1977 Rolls Royce Corniche came from an era when handcrafted luxury, restrained styling, and effortless long-distance motoring defined the car’s appeal. As a coachbuilt grand touring convertible or coupe, the Corniche places as much emphasis on ride quality and presentation as it does on road manners. For this model year, the Corniche uses a 235/70R15 radial tire on a 15-inch rim, so the main decision is less about finding the right size and more about choosing the right type of radial within that fitment. Available choices include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles, making it important to match tire appearance to the car’s intended look and use.
Which Tire Size Is Right for The 1977 Rolls Royce Corniche
The 1977 Rolls Royce Corniche uses one primary tire size: 235/70R15, and it is a radial fitment on a 15-inch rim. The Corniche Base uses that same size, so the key decision is choosing the right radial tire style, brand, and sidewall treatment for the way the car is presented and driven.
The size code 235/70R15 identifies a metric radial tire with a 235 millimeter nominal section width, a 70-series profile, and fitment for a 15-inch wheel. On a 1977 Rolls Royce Corniche, this modern metric radial format suits the car’s late-classic luxury touring character and keeps the selection centered on radial construction rather than an old bias-ply conversion question. Available choices include Cooper, Avon, BFGoodrich, and Michelin, with sidewall options such as blackwall, narrow whitewall, wide whitewall, redline, and RWL across several tire series. That gives Corniche owners room to balance traditional appearance, touring style, and wheel compatibility within the correct size.
Sub-model fitment is straightforward for the 1977 Rolls Royce Corniche. The covered Corniche sub-model uses the same primary tire size, so the main task is confirming wheel condition and choosing the radial style that best suits the car’s appearance and road use.

Tire Size & Fitment
What tire size fits a 1977 Rolls Royce Corniche?
The 1977 Rolls Royce Corniche uses a 235/70R15 tire size. This is a radial fitment, and it is the primary size used for the model year, including the Corniche Base sub-model.
That means the size question is fairly simple, but the selection question still matters. Once 235/70R15 has been confirmed on the car, attention should shift to sidewall style, wheel width compatibility, and whether the goal is a more understated touring look or a more distinctive period-style presentation.
What size rim does a 1977 Rolls Royce Corniche use?
The 1977 Rolls Royce Corniche uses a 15-inch rim diameter with its 235/70R15 tire size. That 15-inch dimension is the wheel diameter the tire is built to mount on.
Wheel diameter should be confirmed before replacing tires, especially on collector cars that may have seen wheel changes over time. Rim width also matters, because the available 235/70R15 products are intended for specific width ranges, so the actual wheel should be checked before choosing among the different radial options.
Does the 1977 Rolls Royce Corniche Base use the same tire size?
Yes. The 1977 Rolls Royce Corniche Base uses the same 235/70R15 radial tire size as the core Corniche fitment. There is no separate primary size for the Base sub-model here.
That consistency makes the buying process easier, because the focus stays on selecting the right tire within one established size. Even so, it is still smart to confirm the car’s current wheel setup, since aftermarket wheels, prior restoration work, or long ownership histories can affect what is actually mounted on the vehicle today.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1977 Rolls Royce Corniche?
Start with the correct size and construction: 235/70R15 radial on a 15-inch wheel. From there, the choice comes down to sidewall appearance, rim-width compatibility, brand, tire series, and whether the car is being kept in a restrained luxury presentation or given a more personalized period look.
A Corniche used for touring may call for a different visual character than one restored for shows or casual weekend use. Checking the wheel width, comparing the product specifications, and deciding how prominent the sidewall treatment should be will usually narrow the field much faster than choosing by brand name alone.
What sidewall styles are available for 1977 Rolls Royce Corniche tires?
The 1977 Rolls Royce Corniche has several 235/70R15 sidewall styles available, including blackwall, narrow whitewall, wide whitewall, redline, and RWL. Those choices can change the look of the car dramatically even when the tire size stays the same.
A blackwall or narrow whitewall usually suits a more understated grand touring presentation, while a wider whitewall creates a more formal vintage look. Redline and raised white letter styles are also available, but those should be chosen carefully so the tire’s appearance fits the personality and finish level of the individual Corniche.
What brands offer tires for the 1977 Rolls Royce Corniche?
The 1977 Rolls Royce Corniche has 235/70R15 tire options from Cooper, Avon, BFGoodrich, and Michelin. The available series include Cobra Radial G/T, Turbosteel, Silvertown Radial, Radial T/A, and Michelin XVS.
Those brand and series differences matter because they influence both appearance and specification details. Some products emphasize traditional luxury-car styling with whitewall options, while others lean toward sportier sidewall treatments such as redline or raised white letters, so the best choice depends on the look of the car and the wheel dimensions being used.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Rolls Royce Corniche?
A period-style starting point for a 1977 Rolls Royce Corniche is the correct 235/70R15 radial size paired with a sidewall treatment that suits the car’s formal late-1970s luxury character. Blackwall, narrow whitewall, and wide whitewall choices are all available within that size.
The right visual direction depends on how the Corniche is being restored or preserved. When exact originality matters, marque-specific references and historical vehicle documentation are worth checking, but for many owners the more immediate decision is choosing a tire that keeps the right overall size while supporting the car’s intended presentation.
How does tire construction affect the appearance of a restored 1977 Rolls Royce Corniche?
On a 1977 Rolls Royce Corniche, the primary fitment is already radial, so the appearance question is less about switching construction and more about selecting the right radial design. The construction stays consistent, but the visual effect changes with sidewall treatment and tire series.
That is why two tires in the same 235/70R15 size can give the car very different character. A blackwall can look restrained and formal, while narrow or wide whitewalls create a more traditional luxury presentation, and redline or RWL styles push the car toward a more personalized period impression.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Rolls Royce Corniche?
Yes. A 1977 Rolls Royce Corniche may use the correct 235/70R15 size from the outside, but wheel changes, suspension alterations, ride-height changes, or bodywork differences can still affect actual fitment. Diameter alone does not confirm that the full wheel-and-tire package is correct.
Collector cars often change hands after years of repairs or cosmetic updates, so it is worth checking wheel width, offset, and clearance at the fender and steering components before installing new tires. Even within the proper size, the car should have enough room through full steering movement and normal suspension travel.
What should I inspect before driving a 1977 Rolls Royce Corniche on new tires?
Before road use, inspect wheel condition, valve stems, lug hardware, tire pressure, and the age and condition of any remaining spare. It also helps to look over the suspension and steering for looseness, since a new set of tires cannot compensate for worn front-end components.
A car like the 1977 Rolls Royce Corniche benefits from a careful walk-around after installation. Check for any sign of rubbing, verify that the tires seat properly on the wheels, and recheck inflation after the first drive so the car is ready for smooth local use or a longer touring outing.
How should 235/70R15 tires on a collector 1977 Rolls Royce Corniche be maintained?
Maintain 235/70R15 tires on a collector 1977 Rolls Royce Corniche by keeping inflation consistent, inspecting sidewalls and tread regularly, and watching for cracking, bulges, cuts, or slow air loss. Cars that are driven infrequently deserve closer inspection because tire aging can matter even when tread wear is minimal.
Storage conditions also make a difference. Keeping the car away from prolonged heat, direct sunlight, and ozone sources can help preserve the tires, and periodic checks of wheel alignment and balance support smooth touring behavior. Any unusual vibration or visible wear pattern is a reason to inspect the setup before more road time.
