The 1974 Rolls Royce Corniche sits firmly in the era of hand-built grand touring luxury, blending formal coachwork, substantial road presence, and the kind of effortless cruising character buyers still expect from a Rolls-Royce convertible or coupe. Tire choice matters here because the car’s look and road manners depend heavily on maintaining the proper stance and profile. The 1974 Rolls Royce Corniche uses a 235/70R15 radial tire on a 15-inch rim. Within that size, there are meaningful choices in blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles across several premium touring and classic-oriented series. The right selection depends on whether the goal is refined road use, a more traditional presentation, or restoration-minded appearance.
Which Tire Size Is Right for The 1974 Rolls Royce Corniche
The 1974 Rolls Royce Corniche uses one primary tire size: 235/70R15, a radial fitment on a 15-inch rim. The Corniche Base uses that same size, so the main decision is not which primary size fits, but which version of that size best matches the car’s appearance, wheel specifications, and intended road use.
235/70R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On a 1974 Rolls Royce Corniche, this size supports the proper grand-touring profile expected from a large luxury car of the period. Available choices include Avon, BFGoodrich, Cooper, and Michelin products, with sidewall treatments ranging from blackwall and narrow whitewall to wide whitewall, redline, and raised white letter. This is the size to evaluate when preserving the Corniche’s intended stance while choosing a tire appearance that suits either formal restoration character or regular road use.
Fitment is straightforward for the covered 1974 Rolls Royce Corniche sub-models. The key point is simply confirming the vehicle as a Corniche Base, since tire sizing remains consistent and the real choice shifts to sidewall style, tire series, and wheel compatibility within the same size.

Tire Size & Fitment
What tire size fits a 1974 Rolls Royce Corniche?
The 1974 Rolls Royce Corniche uses a 235/70R15 radial tire. That is the primary fitment for this model, and the covered Corniche Base application uses the same size on a 15-inch rim.
Using the correct size helps preserve the car’s proportions and keeps product selection focused where it belongs: sidewall style, series, and wheel compatibility. Before choosing a tire, it is still worth confirming that the car has its expected 15-inch wheels and has not been changed to a different wheel or suspension setup over the years.
What size rim does a 1974 Rolls Royce Corniche use?
The 1974 Rolls Royce Corniche uses a 15-inch rim with its 235/70R15 tire fitment. Product offerings in this size also show rim-width compatibility that generally falls in the 6.0- to 8.5-inch range, depending on the specific tire.
Rim diameter is the first confirmation point, especially on a collector car that may have seen wheel changes during its life. After verifying the 15-inch diameter, compare the actual wheel width against the tire’s approved range so the selected radial has the right foundation for safe mounting and the intended visual profile.
Does the 1974 Rolls Royce Corniche Base use the same tire size?
Yes. The 1974 Rolls Royce Corniche Base uses the same 235/70R15 radial tire size as this application. There is no separate primary tire size to sort through at the sub-model level here.
That makes the buying decision much simpler, because the focus moves away from fitment differences between trims and toward selecting the right tire style. Owners can compare blackwall, whitewall, redline, or raised white letter options, while still checking the car’s actual wheels for correct diameter and width before mounting.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1974 Rolls Royce Corniche?
Start with the confirmed 235/70R15 size and the car’s 15-inch wheels, then compare the character of the available radial tires. This application includes touring-oriented and classic-style choices from Avon, BFGoodrich, Cooper, and Michelin, along with differences in sidewall treatment and approved rim-width ranges.
A Corniche owner usually ends up balancing appearance and use. A formal restoration-minded presentation may lean toward whitewall styles, while a different look might point to blackwall, redline, or raised white letters. Matching the tire’s rim-width specification to the actual wheel is just as important as selecting the visual style.
What sidewall styles are available for 1974 Rolls Royce Corniche tires?
The 1974 Rolls Royce Corniche has 235/70R15 tire options in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, redline, and RWL, which is raised white letter. Those choices create very different visual results even though the tire size itself stays the same.
Sidewall style matters on a car with the Corniche’s strong visual presence because the tire contributes heavily to the finished stance. Whitewall treatments usually support a more formal luxury presentation, while blackwall, redline, or RWL can shift the look noticeably. Choosing the sidewall should come after confirming the correct size and wheel dimensions.
What brands offer tires for the 1974 Rolls Royce Corniche?
Tires for the 1974 Rolls Royce Corniche in 235/70R15 are available from Avon, BFGoodrich, Cooper, and Michelin. The available series include Turbosteel 70 CR11B, Silvertown Radial, Cobra Radial G/T, Radial T/A, and Michelin XVS.
Brand choice is only part of the decision, since each series brings its own visual character and specification details. A useful comparison includes sidewall style, approved rim-width range, and whether the tire’s overall presentation matches the way the Corniche is being used, whether that means regular road miles or a more restoration-oriented approach.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Rolls Royce Corniche?
A period-style 1974 Rolls Royce Corniche starts with the correct 235/70R15 radial size and then narrows the choice by appearance. In this application, blackwall, narrow whitewall, and wide whitewall options create the most obvious visual differences, while the tire series itself can also influence the overall presentation.
For many Corniche owners, the tire should support the car’s formal luxury character rather than overpower it. Whitewall options often suit that goal well, but exact originality should be checked against marque-specific references, historic photos, or restoration documentation if authenticity matters more than general period style.
Does correct tire fitment matter for a 1974 Rolls Royce Corniche restoration?
Yes. Correct tire fitment matters on a 1974 Rolls Royce Corniche restoration because tire size, construction, and sidewall style all affect the car’s stance and overall visual balance. Using the proper 235/70R15 radial size keeps the restoration grounded in the correct proportions for the car.
Appearance is only part of the equation. The selected tire also needs to suit the wheel diameter and width actually on the car, especially if wheels have been changed during an older restoration. Getting those details right helps avoid a finished look that appears too modern, too aggressive, or simply out of scale.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Rolls Royce Corniche?
Yes. Modifications can affect tire fitment on a 1974 Rolls Royce Corniche even when the intended tire size remains 235/70R15. Aftermarket wheels, altered wheel width, suspension changes, or body and steering adjustments can all change the clearance picture around the tire.
That is why the car should be checked as it sits today rather than treated as untouched. Confirm the wheel diameter, measure wheel width, and inspect clearance at full steering lock and through suspension travel. Those steps matter most when the car no longer carries its original-style wheel and suspension layout.
What should I inspect before driving a 1974 Rolls Royce Corniche on new tires?
Before driving a 1974 Rolls Royce Corniche on new tires, inspect the wheels for correct diameter and condition, verify valve stems, and make sure each tire is mounted in the proper 235/70R15 application. Tire pressure should be set correctly, and the car should be checked for any obvious alignment or suspension issues.
A short shakedown drive is a smart next step on a collector car, especially one that may have spent time stored. Watch for vibration, pulling, rubbing, or uneven response, then recheck air pressure after the initial drive. It is also wise to inspect older spare tires and any wheel hardware before longer road use.
How should 235/70R15 tires on a collector 1974 Rolls Royce Corniche be maintained?
235/70R15 tires on a collector 1974 Rolls Royce Corniche should be inspected regularly for air loss, tread wear, sidewall cracking, bulges, and cuts. Even on a low-mileage car, age and storage conditions can matter as much as mileage, particularly when the vehicle spends long periods parked.
Consistent inflation, clean storage conditions, and protection from prolonged sun, heat, and ozone sources help preserve the tires between drives. Moving the car periodically can also help avoid flat spotting during long storage. A close visual inspection before each outing is good practice for a large, luxury collector car that may not be driven often.
