The 1947 Bentley Mark comes from the immediate postwar period, when British luxury cars balanced formal coachwork, quiet road manners, and long-distance touring character. For many owners, the appeal lies in preserving that refined pre- and postwar transition feel rather than treating the car like a modern sedan. Tire choice reflects that split, because this Bentley Mark uses either a 650-16 bias-ply fitment or a 185R16 radial on a 16-inch rim. That opens the door to traditional blackwall and wide whitewall bias-ply styles, or classic blackwall radial options from Michelin, Avon, and Vredestein. The right choice depends on whether appearance, steering feel, and road use lean more toward restoration presentation or regular touring.
Which Tire Size Is Right for The 1947 Bentley Mark
The 1947 Bentley Mark uses two primary tire sizes, and the choice is tied mainly to construction rather than wheel diameter, since both fitments use a 16-inch rim. The first step is deciding whether the car should stay with a traditional 650-16 bias-ply setup or move to a 185R16 radial, then confirming the actual wheel width and overall vehicle setup before selecting a tire.
185R16 is a Euro-metric radial size in which 185 identifies the nominal section width in millimeters, the R indicates radial construction, and 16 is the rim diameter in inches. On a 1947 Bentley Mark, this size suits owners looking for a classic radial format while staying on a 16-inch wheel. Available choices center on blackwall radials from Michelin, Avon, and Vredestein, with series such as Michelin X Radial, Turbosteel CR6D, and Sprint Classic. It is a useful size to evaluate when touring use and a traditional blackwall presentation both matter.
650-16 is a numeric bias-ply size, with the leading number representing a nominal section width of about 6.50 inches and the 16 identifying the wheel diameter. This is the traditional construction choice for the 1947 Bentley Mark and gives the car a distinctly period-style tire presentation. Within this size, there is broad variety in blackwall and wide whitewall designs across brands including BFGoodrich, Firestone, Goodyear, Coker Classic, Garfield, Lester, and Excelsior, plus several classic bias-ply series. It is the size to study closely when restoration appearance and vintage construction are central to the decision.
Fitment is straightforward here because the covered Bentley Mark sub-model shares the same two tire-size paths. Checking the exact sub-model still matters, since the decision is less about model variation and more about whether the car should run 650-16 bias-ply tires or 185R16 radials.

1947 Bentley Mark VI
The 1947 Bentley Mark VI uses the same 16-inch wheel diameter whether it is equipped with 650-16 bias-ply tires or 185R16 radials. That means the real selection point is choosing the construction and appearance that suit the car, then confirming wheel width and overall clearance before settling on a specific tire.
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.
Best 1947 Bentley Mark Tires for Sale
Available 1947 Bentley Mark tires span two distinct directions: blackwall 185R16 radials from Michelin, Avon, and Vredestein, or a much broader selection of 650-16 bias-ply tires in blackwall and wide whitewall styles across several classic series. Rim-width requirements also vary by tire family.
These FAQs focus on the exact tire choices for the 1947 Bentley Mark, including size meaning, 16-inch rim fitment, bias-ply versus radial selection, appearance considerations, and the wheel, suspension, and condition checks worth making before road use.
Tire Size & Fitment
What tire size fits a 1947 Bentley Mark?
The 1947 Bentley Mark uses two primary tire sizes: 650-16 in bias-ply construction and 185R16 in radial construction. Both sizes are associated with the Bentley Mark VI and both use a 16-inch rim, so the fitment question is really about which construction and tire style suit the car.
A buyer should first confirm whether the car still has wheels suited to the intended tire type, especially if it has been restored or modified over the years. Once that is settled, the choice shifts to appearance, driving character, and whether the goal is a traditional bias-ply presentation or a classic-style radial setup.
What size rim does a 1947 Bentley Mark use?
The 1947 Bentley Mark uses a 16-inch rim with both of its primary tire sizes, 650-16 and 185R16. That shared rim diameter simplifies the first stage of selection because the main difference between the two fitments is construction, not wheel diameter.
Rim diameter is only part of the picture, so wheel width still needs to be checked before choosing a specific tire. Some 650-16 bias-ply options are intended for narrower wheels, while several 185R16 radial products call for a broader rim-width range, making actual wheel measurement an important step.
What does 650-16 mean on a 1947 Bentley Mark?
On a 1947 Bentley Mark, 650-16 is a vintage numeric bias-ply tire size. The 650 portion refers to an approximate nominal section width of 6.50 inches, and the 16 indicates the tire fits a 16-inch rim.
That size format matters because it points to an older bias-ply tire system rather than a modern metric radial one. If the goal is a restoration-oriented look, 650-16 opens up traditional blackwall and wide whitewall choices, but the wheel width and the car's present setup still deserve a careful check before selecting a specific tire.
Bias-Ply & Radial Options
Is 650-16 a bias-ply or radial tire for the 1947 Bentley Mark?
For the 1947 Bentley Mark, 650-16 is a bias-ply tire size. It represents the traditional vintage construction offered for this car, while 185R16 serves as the radial alternative on the same 16-inch rim diameter.
That distinction affects both the car's look and the way an owner approaches tire selection. A 650-16 setup is usually chosen for period-style presentation, while a radial move calls for confirming that the wheel width and overall vehicle setup are appropriate for the different construction and sizing format.
Should I use bias-ply or radial tires on a 1947 Bentley Mark?
A 1947 Bentley Mark can be equipped with either 650-16 bias-ply tires or 185R16 radial tires. Bias-ply suits owners who want a more traditional vintage presentation, while 185R16 radials appeal to owners looking for a classic radial format on a 16-inch wheel.
The right choice depends on how the car is used and how closely the tire should reflect a period-style appearance. Wheel width, tire clearance, and the condition of steering and suspension components should all be reviewed before changing construction, especially on a collector car that may have gone through decades of repairs or updates.
What should I check before converting my 1947 Bentley Mark from bias-ply to radial tires?
Moving a 1947 Bentley Mark from 650-16 bias-ply tires to 185R16 radials starts with confirming the 16-inch wheel setup and measuring the wheel width. The car should also be checked for adequate clearance at the fenders and steering range because a radial uses a different size convention and construction.
A conversion is also a good time to inspect suspension wear, steering play, and general wheel condition so the car is working with the new tire type rather than against it. Owners should compare the chosen radial's rim-width requirements with the actual wheels on the car before making the switch.
Choosing the Right Tire
What should I consider when choosing a 1947 Bentley Mark tire?
Start with the correct primary fitment path: 650-16 if the goal is a traditional bias-ply setup, or 185R16 if the car is being equipped with a radial. From there, compare wheel compatibility, sidewall appearance, brand, tire series, and whether the car is being prepared for show-focused presentation or regular touring use.
A narrow decision based only on size can miss important details, especially on an older Bentley with a long service history. The wheel width, the condition of the chassis, and the car's present stance all deserve attention so the selected tire matches both the vehicle and the owner's intended use.
What sidewall styles are available for 1947 Bentley Mark tires?
The 1947 Bentley Mark has two main sidewall directions. The 185R16 radial options are blackwall, while the 650-16 bias-ply range includes both blackwall and wide whitewall styles.
That makes sidewall choice one of the biggest appearance decisions on this page, particularly for owners aiming for a specific restoration flavor. A blackwall usually keeps the presentation restrained and formal, while a wide whitewall creates a more decorative period-style look, so the tire should match the car's trim, finish, and intended character.
What brands offer tires for the 1947 Bentley Mark?
Brand choice depends on the size and construction selected for the 1947 Bentley Mark. In 185R16 radial form, available brands include Michelin, Avon, and Vredestein, while 650-16 bias-ply tires are offered by BFGoodrich, Coker Classic, Firestone, Garfield, Lester, Goodyear, Excelsior, STA, and Tornel.
The practical next step is not picking a brand by name alone, but comparing what each brand offers within the intended tire category. Sidewall treatment, tire series, rim-width suitability, and whether the tire is aimed at passenger-car styling or more utility-oriented use can matter just as much as the brand label.
Restoration & Appearance
Which tire should I choose for a period-style 1947 Bentley Mark?
For a period-style 1947 Bentley Mark, the 650-16 bias-ply fitment is the natural starting point because it preserves the vintage size format and traditional construction associated with the car's era. That size is available in several classic bias-ply series and in both blackwall and wide whitewall treatments.
The best visual match depends on how the individual car has been restored and how formal or understated the finished presentation should be. When exact originality matters, marque references and restoration history should guide the final appearance choice rather than assuming any one brand or sidewall treatment is automatically correct.
How does tire construction affect the appearance of a restored 1947 Bentley Mark?
Tire construction changes the look of a restored 1947 Bentley Mark as much as the size itself. A 650-16 bias-ply tire gives the car a more traditional visual character, while a 185R16 radial introduces a later-style sizing format and is only offered here as a blackwall.
That difference matters on a postwar luxury car where stance and sidewall presentation contribute strongly to the finished impression. Owners restoring for authenticity-minded display often begin with the bias-ply route, while owners prioritizing driving use may accept the radial's different look in exchange for a classic touring-oriented setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1947 Bentley Mark?
Yes, modifications can affect tire fitment on a 1947 Bentley Mark even when the nominal size appears correct. Aftermarket wheels, altered wheel width, suspension work, brake updates, or body changes can all influence whether a 650-16 bias-ply tire or a 185R16 radial has the clearance and wheel support it needs.
A Bentley that has passed through several owners may not still match its earlier setup, so physical inspection matters more than assumptions. Checking lock-to-lock steering clearance, fender space, and the actual wheel dimensions is especially important before changing construction or choosing a wider- or differently-profiled tire family.
What should I inspect before driving a 1947 Bentley Mark on new tires?
Before driving a 1947 Bentley Mark on new tires, inspect the wheels, valve hardware, and the surrounding suspension and steering components. The tires themselves should be checked for correct mounting, proper air retention, and clearances at full steering travel so the car is ready for cautious initial road use.
A collector car also deserves a look at brake function, alignment condition, and any signs of rubbing after the first miles. Early road testing should be gradual, with pressure rechecked afterward, because long-stored cars often reveal wheel, chassis, or balance issues only once they are back in motion.
How should 650-16 or 185R16 tires on a collector 1947 Bentley Mark be maintained?
Collector-car tires on a 1947 Bentley Mark should be inspected regularly for cracking, flat spotting, bulges, cuts, uneven wear, and slow air loss, whether the car runs 650-16 bias-ply tires or 185R16 radials. Pressure should be monitored consistently, especially on a vehicle that spends long periods parked between drives.
Storage conditions matter just as much as mileage on a low-use Bentley. Keeping the car away from prolonged heat, direct sunlight, excess moisture, and ozone sources helps preserve the tires, and occasional movement can reduce set-in flat spotting during long indoor storage periods.
