Rolls Royce Corniche Tires

Rolls Royce Corniche uses two tire sizes across the 1971 through 1979 range. Cars from 1971, 1972, and 1973 use 205R15 on 15-inch rims, while cars from 1974 through 1979 use 235/70R15 on 15-inch rims. Both are radial-type fitments, but they represent different section widths and overall profile styles within the same wheel diameter.

The practical step is to identify the model year first, then confirm the tire size already fitted to the car or listed on service records and wheel information. Because both sizes mount on 15-inch wheels, it is easy to assume they interchange, but the later size is visibly wider and lower in profile. Matching the tire to the correct production period helps preserve the intended stance, steering feel, and appearance of the Rolls Royce Corniche.

On a Rolls Royce Corniche, 205R15 is an older Euro-metric radial size used on 1971 through 1973 cars. The 205 refers to section width in millimeters, the R identifies radial construction, and the 15 gives the wheel diameter in inches. Unlike later metric sizes such as 235/70R15, this format does not spell out the aspect ratio in the size code.

That older format matters because many owners mistake 205R15 for a simpler modern metric size when it is really a period radial designation with its own proportions. If your Rolls Royce Corniche is an early car, use the wheel diameter and year together rather than substituting by width alone. Preserving the correct early size keeps the car closer to its original visual balance and avoids guesswork between early and later production fitments.

Rolls Royce Corniche uses a 15-inch rim diameter throughout the 1971 to 1979 range covered here. The early 205R15 fitment and the later 235/70R15 fitment both mount on 15-inch wheels, so the change in 1974 is a tire size change rather than a wheel diameter change. That makes the wheel diameter straightforward even though the tire dimensions differ by year.

The main fitment question is not whether the wheel is 15 inches, but which of the two 15-inch tire sizes belongs on the specific Rolls Royce Corniche. A quick check of the existing tires, the wheel stamping, and the car’s production year usually settles the matter. If the car has been restored or modified in the past, verify the installed size carefully instead of assuming the current tires reflect original-era fitment.

A 1974 Rolls Royce Corniche falls into the later size group and uses 235/70R15 rather than the earlier 205R15 fitment. The production break in this range occurs after 1973, with 1971-1973 cars using 205R15 and 1974-1979 cars using 235/70R15. Both sizes fit 15-inch rims, so the key identifier is the model year together with the tire size already fitted to the car.

For a 1974 Rolls Royce Corniche, confirm that the car has not been retrofitted with earlier wheels or maintained on an older size out of habit. Check the sidewall markings on the current tires and compare the overall width and profile to the later specification. Once the size is settled, you can choose among period-appropriate blackwall, whitewall, or other sidewall treatments depending on how original or personalized you want the car to appear.

Rolls Royce Corniche tires are offered here in several sidewall styles, including blackwall, wide whitewall, narrow whitewall, redline, and raised white letter designs. The early 205R15 options include blackwall and wide whitewall, while the later 235/70R15 group adds blackwall, wide whitewall, narrow whitewall, redline, and RWL choices. That gives owners a broad range of visual treatments within the correct size families.

A conservative restoration or formal touring presentation usually leans toward blackwall or whitewall depending on the car’s look and trim, while redline and raised white letter styles create a more assertive custom effect. The best approach is to decide first on the correct size for the year, then choose the sidewall that suits the character of your Rolls Royce Corniche. Sidewall style changes the car’s visual impression more than many owners expect.

Rolls Royce Corniche tires in these sizes are available from Phoenix, Avon, Cooper, BFGoodrich, and Michelin. The early 205R15 size is represented by Phoenix and Avon, while the later 235/70R15 size adds Cooper, BFGoodrich, and Michelin alongside Avon. Those brands cover a mix of touring-oriented radial offerings and more style-driven sidewall presentations.

Brand choice should come after you have matched the correct size to the production year of your Rolls Royce Corniche. Once that is settled, compare sidewall appearance, tread style, and the general character you want from the car, whether formal, understated, or more personalized. Owners pursuing a factory-like look often narrow the field by appearance first, then refine the choice by construction details and the tire’s visual proportion on the wheel.

Rolls Royce Corniche tires here appear in several series, including European Passenger, Textile, Cobra Radial G/T, Silvertown Radial, Turbosteel 70 CR11B, Michelin XVS, and Radial TA. All of them are radial constructions, but they differ in period character, sidewall presentation, and intended visual style. Some series are more formal touring tires, while others emphasize whitewall, redline, or raised white letter appearance.

That distinction matters because a Rolls Royce Corniche can look noticeably different depending on the tire series chosen, even when the size is correct. A formal luxury presentation usually favors the more restrained touring-style series, while enthusiast-oriented raised letter or redline series create a more personalized statement. Narrow your choice by first selecting the correct year-specific size, then choosing the series that best matches the car’s restoration philosophy and intended use.

A Rolls Royce Corniche should be stored on a clean, dry surface away from direct sunlight, electric motors, ozone sources, and wide temperature swings. Keep the tires properly inflated, and if the car will sit for long periods, move it periodically or support it in a way that reduces flat-spotting. Collector cars with heavy curb weight benefit from regular position changes during storage.

Good storage habits matter because even high-quality radial tires can age unevenly when a luxury grand tourer remains stationary for months at a time. Keeping the Rolls Royce Corniche clean, covered, and out of harsh light helps preserve both sidewall appearance and carcass condition. If the car is driven only seasonally, make tire inspection part of the routine before each return to service rather than assuming the tires are unchanged from last year.

Tires on a Rolls Royce Corniche should be visually inspected before regular road use and given a more thorough inspection several times during the driving season. Look for cracking, bulges, irregular wear, punctures, and signs of age around the bead and sidewall, especially on a collector car that may spend long periods parked. Inflation pressure should also be checked routinely because low-use cars often lose pressure gradually.

Frequent inspection is especially important on a Rolls Royce Corniche because these cars are often driven less than modern daily transportation, which means age can become a bigger issue than tread wear. Any change in ride quality, vibration, or steering feel deserves immediate attention. A scheduled inspection pattern also helps catch alignment or suspension issues early, before they spoil an expensive set of tires.

Tires on a Rolls Royce Corniche should be replaced when age, cracking, hardening, bulging, impact damage, or structural deterioration appears, even if the tread still looks usable. Collector cars often age out tires before they wear them out, particularly when they are stored for long periods and driven occasionally. A tire that looks presentable can still be well past its best service life.

The right approach is to treat condition and age as seriously as tread depth on a Rolls Royce Corniche. If there is any doubt about the integrity of an older tire, have it inspected by a professional familiar with collector vehicles and low-mileage use patterns. Replacement intervals are often driven by calendar age and storage history rather than mileage, which is why periodic expert review is part of responsible ownership.

Rolls Royce Corniche used two period fitment groups across the years covered here: 205R15 for 1971 through 1973 and 235/70R15 for 1974 through 1979. The available tire series include European Passenger, Textile, Turbosteel 70 CR11B, Michelin XVS, Silvertown Radial, Cobra Radial G/T, and Radial TA. That means the important original-era starting point is the correct year-specific size first, then the most appropriate style and series for the car’s intended presentation.

For restoration work, begin with the production year of the Rolls Royce Corniche and then compare the car against period photos, service records, and marque club guidance. Sidewall style can matter almost as much as the size itself when the goal is authenticity. A car restored for formal concours presentation may call for a different visual treatment than one restored for regular touring, even within the same correct size range.

Correct tire fitment can absolutely affect how a Rolls Royce Corniche is judged and how seriously a restoration is taken. Judges and knowledgeable buyers notice size, sidewall style, overall proportion, and whether the tire suits the car’s year and character. A visibly incorrect profile or an overly modern appearance can distract from otherwise strong restoration work.

For that reason, owners should think of tires as a visible restoration component rather than a simple maintenance item. Matching the correct year-specific Rolls Royce Corniche size and choosing a sidewall style that complements the car’s era helps preserve both visual credibility and presentation value. Marque clubs, period photography, and restoration references are the best final check when the goal is judged authenticity.

Rolls Royce Corniche tires are available here in blackwall, wide whitewall, narrow whitewall, redline, and raised white letter forms. For a traditional luxury presentation, blackwall and whitewall styles generally align more naturally with the formal character of the model than redline or raised white letter designs. The early 205R15 range is more limited, while the later 235/70R15 size offers a wider spread of visual options.

The right choice depends on whether the Rolls Royce Corniche is being restored to a restrained factory-style look or presented with a more personalized period flavor. Whitewall width can noticeably change the visual weight of the car, especially on a large luxury grand tourer. When authenticity matters, compare your intended sidewall style to period images and the specific trim and color combination of the car.

These radial tires are intended for road use on a Rolls Royce Corniche when they are correctly sized, properly mounted on the right 15-inch wheels, and in sound condition. The available offerings include modern radial constructions in both the early 205R15 and later 235/70R15 fitments. Safety depends on selecting the correct year-specific size and ensuring the tires themselves are healthy and professionally installed.

Before any public-road driving, treat the tire choice as one part of the overall condition of the Rolls Royce Corniche. A proper inspection should include tire age, inflation pressure, wheel condition, suspension wear, and brake performance, especially on a collector car that may not be exercised regularly. Even the correct size cannot compensate for an undermaintained chassis or an aged tire that has spent years in storage.

Before driving a Rolls Royce Corniche, check that the tire size matches the car’s production period, confirm inflation pressure, inspect sidewalls and tread for visible deterioration, and verify that the tires are seated on 15-inch rims in good condition. A 1971-1973 car should be on 205R15, while a 1974-1979 car should be on 235/70R15. Any vibration, visible cracking, or uneven wear deserves attention before the car goes out on the road.

That walkaround is especially important on a Rolls Royce Corniche because many examples are driven infrequently and can develop age-related issues without accumulating many miles. Include a quick look at valve stems, wheel balance history, and any signs that the car has been sitting under load for long periods. A few careful minutes in the garage can prevent preventable problems once the car is at speed.

A Rolls Royce Corniche should only be driven at speeds appropriate to the exact tire fitted, its condition, and the overall mechanical state of the car. The tires listed here are radial constructions, and some include service descriptions such as 97V, 101V, 101H, and 102S, but those markings do not override age, storage history, or the need for a healthy chassis. Real-world safe speed is always lower when the tire is old or the car has not been recently inspected.

The sensible approach is to build speed gradually after inspection and use, not to assume that a luxury grand tourer can be driven hard simply because the size is correct. On a Rolls Royce Corniche, smooth touring use is far more appropriate than aggressive driving unless the entire car has been sorted accordingly. If there is any uncertainty about tire age or condition, keep speeds conservative until the setup has been professionally evaluated.
