The 1989 Rolls-Royce Silver Spur belongs to an era when Rolls-Royce emphasized long-wheelbase comfort, formal luxury, and quiet road manners over overt flash. Owners tend to value these cars for their composed presence as much as their craftsmanship, so tire choice has a noticeable effect on both stance and driving character. This model uses a 235/70R15 radial tire on a 15-inch rim, keeping the fitment question focused and straightforward. Within that size, the real choices are brand, tire series, and sidewall presentation, including blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles. The best match depends on whether the goal is formal touring appearance, restoration-minded styling, or general collector-car road use.
Which Tire Size Is Right for The 1989 Rolls-Royce Silver Spur
The 1989 Rolls-Royce Silver Spur uses one primary tire size: 235/70R15, and it is a radial fitment for a 15-inch rim. The Silver Spur Base uses the same size, so the decision is less about identifying among multiple fitments and more about choosing the right brand, sidewall style, and tire series for the car’s appearance and intended use.
235/70R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 1989 Rolls-Royce Silver Spur, this is the core fitment and it suits the car’s luxury-touring character. Available choices in this size include Michelin, Avon, BFGoodrich, and Cooper, with sidewall treatments ranging from blackwall and narrow whitewall to wide whitewall, redline, and raised white letter. That gives buyers room to balance a more formal Rolls-Royce presentation against a more personalized period-style look.
Fitment is straightforward for the covered 1989 Rolls-Royce Silver Spur sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the car retains its intended wheel and tire setup before comparing brands or sidewall styles.

Tire Size & Fitment
What tire size fits a 1989 Rolls-Royce Silver Spur?
The 1989 Rolls-Royce Silver Spur uses a 235/70R15 radial tire. That size is the primary fitment for the model and keeps the selection process centered on finding the right tire within one established size rather than sorting through multiple factory fitments.
The practical next step is confirming that the car still carries 15-inch wheels and has not been changed to an aftermarket wheel and tire package over the years. Once wheel size is confirmed, the main comparison points become brand, sidewall style, rim-width compatibility, and whether the tire’s visual character suits a formal luxury sedan.
What size rim does a 1989 Rolls-Royce Silver Spur use?
The 1989 Rolls-Royce Silver Spur uses a 15-inch rim with its 235/70R15 tire fitment. The tire size itself confirms the wheel diameter, since the final number in 235/70R15 refers to a 15-inch wheel.
Wheel diameter is only one part of the fitment picture, so it is still worth checking actual wheel width before choosing among available tires. Several 235/70R15 options are intended for rim widths in the 6.0- to 8.5-inch range, and confirming that measurement helps narrow the field to tires that match the car’s existing wheel setup.
Does the 1989 Rolls-Royce Silver Spur Base use the same tire size?
Yes. The 1989 Rolls-Royce Silver Spur Base uses the same 235/70R15 radial tire size as the overall model fitment. That makes the Base straightforward from a sizing standpoint, with no separate primary tire size to sort out first.
Since the size remains the same, the choice usually comes down to appearance and product style rather than basic fitment differences between trims. Owners can focus on whether a blackwall, whitewall, redline, or raised white letter look makes the most sense for the car’s presentation, while still confirming the existing wheel dimensions before installation.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1989 Rolls-Royce Silver Spur?
Start with the correct size and construction: 235/70R15 radial on a 15-inch rim. From there, the most important differences are brand, tire series, sidewall appearance, and wheel-width compatibility, since this size is available in several distinct versions suited to different visual goals.
A formal, restoration-oriented Silver Spur often leads buyers toward blackwall or whitewall presentations, while redline or raised white letter options create a more personalized period-style look. It also helps to compare rim-width ranges, weight, and load figures where stated so the chosen tire suits both the wheel and the way the car will actually be used.
What sidewall styles are available for 1989 Rolls-Royce Silver Spur tires?
235/70R15 tires for the 1989 Rolls-Royce Silver Spur are available in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, redline, and raised white letter. That range gives the car owner considerable freedom to shape the car’s finished appearance without changing the basic tire size.
For a conservative luxury presentation, blackwall or whitewall styles usually look more at home on a Silver Spur than performance-oriented lettering. Redline and raised white letter options can still appeal when the goal is a period-style custom touch, but sidewall choice should be made with the car’s paint, wheel treatment, and restoration direction in mind.
What brands offer tires for the 1989 Rolls-Royce Silver Spur?
The 1989 Rolls-Royce Silver Spur’s 235/70R15 fitment is available from Michelin, Avon, BFGoodrich, and Cooper. Those brands appear across several tire series, giving owners a mix of touring-oriented and appearance-driven options within the same basic size.
Brand choice works best when paired with the details that actually affect the finished result, such as sidewall treatment, series styling, rim-width specification, and load information where stated. Instead of treating brand alone as the answer, compare the full tire package against the Silver Spur’s wheel setup and the look you want the car to carry.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Rolls-Royce Silver Spur?
A period-style choice for a 1989 Rolls-Royce Silver Spur usually starts with staying in the correct 235/70R15 radial size and then selecting a sidewall treatment that suits the car’s formal luxury character. Blackwall, narrow whitewall, and wide whitewall options are all available and each creates a different visual impression.
The right answer depends on whether the car is being preserved as a restrained luxury sedan or finished with a more noticeable collector-car presentation. When exact originality matters, it is wise to compare the chosen look against marque references, period photos, or vehicle-specific restoration documentation rather than assuming any current sidewall style is automatically exact.
How does tire construction affect the appearance of a restored 1989 Rolls-Royce Silver Spur?
On the 1989 Rolls-Royce Silver Spur, construction is less of a debate than it is on earlier collector cars because the primary fitment is already radial. That means the appearance difference comes more from the tire series and sidewall style than from choosing between bias-ply and radial construction.
A restored Silver Spur can look notably different depending on whether it wears blackwalls, narrow whitewalls, wider whitewalls, or a more stylized sidewall such as redline. Keeping the proper 235/70R15 size helps preserve proportion, while the final sidewall choice should support the car’s trim level, wheel finish, and restoration objective.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Rolls-Royce Silver Spur?
Yes. Even though the primary fitment is straightforward at 235/70R15 on a 15-inch wheel, changes to wheels, suspension height, alignment settings, or body clearance can alter what works on a particular 1989 Rolls-Royce Silver Spur. Collector cars often pick up non-original parts over time, even when they appear stock at a glance.
The safest approach is to verify actual wheel diameter and width on the car before choosing among available 235/70R15 tires. It also helps to inspect clearance at full steering lock and under normal suspension load, especially if the Silver Spur has aftermarket wheels, replacement springs, or any prior body and suspension work.
What should I inspect before driving a 1989 Rolls-Royce Silver Spur on new tires?
Before putting a 1989 Rolls-Royce Silver Spur back on the road with new tires, inspect the wheels for damage, confirm proper wheel size, and check that the suspension and steering components are in sound condition. Tire age on the removed set can also reveal whether the car has been sitting for long periods.
Once the new tires are installed, keep an eye on air pressure, look for any rubbing during turns, and make sure the car tracks evenly without vibration. A careful first road test is worthwhile on a large luxury sedan like the Silver Spur, since alignment condition and wheel balance strongly influence how composed the car feels.
How should 235/70R15 tires on a collector 1989 Rolls-Royce Silver Spur be maintained?
235/70R15 tires on a collector-driven 1989 Rolls-Royce Silver Spur should be inspected regularly for air loss, sidewall cracking, tread wear, cuts, and bulges, even if the car covers very few miles. Low annual mileage does not stop tires from aging, and long storage periods can hide developing condition issues.
Routine pressure checks and occasional visual inspection of the full tread and sidewall are especially important on a heavy luxury car. Storage conditions matter as well, so keeping the Silver Spur away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition between drives and show outings.
