1961 Singer Gazelle Tires

The 1961 Singer Gazelle is associated with two tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both are 15-inch fitments, so the choice is not about changing wheel diameter first, but about selecting the construction and appearance that best suits the car.

For a more traditional presentation, 560-15 keeps the vintage numeric bias-ply format. For owners considering radial construction, 155R15 is the relevant fitment. Before choosing either one, confirm the wheel width, check whether the car still has its original wheel setup, and make sure the intended tire works with the Gazelle’s current clearance and suspension condition.

The 1961 Singer Gazelle uses a 15-inch rim with both of its associated tire sizes. That applies to the 560-15 bias-ply fitment and the 155R15 radial fitment, so wheel diameter remains consistent even though the tire construction and sizing format differ.

Rim diameter is only part of the fitment picture. Wheel width still matters, especially when comparing vintage bias-ply tires with radial alternatives. A Gazelle that has replacement wheels, altered suspension, or a long service history may no longer match its original wheel setup, so measuring the actual wheel on the car is a smart step before selecting a new set of tires.

560-15 is a vintage numeric bias-ply tire size. The 560 indicates an approximate 5.60-inch nominal section width, and the 15 identifies the wheel diameter in inches. On a 1961 Singer Gazelle, it represents the traditional bias-ply sizing system used on many cars of the period.

That size matters not just for fitment, but for how the car looks and feels on the road. A 560-15 bias-ply tire keeps the Gazelle in a period-style format and also opens up sidewall choices such as blackwall, narrow whitewall, and wide whitewall. Any switch away from that format should include a careful look at wheel width, tire dimensions, and vehicle clearance.

On the 1961 Singer Gazelle, 560-15 is the bias-ply tire size. It uses the vintage numeric bias-ply sizing system and remains the traditional construction choice for owners who want a tire format that matches the car’s period character more closely than a modern radial layout.

Choosing 560-15 usually means the decision shifts to brand, sidewall style, and the overall presentation you want from the car. It is available in blackwall, narrow whitewall, and wide whitewall forms. If the Gazelle is being converted away from bias-ply construction, the wheel width and the car’s current setup should be checked rather than assuming any radial alternative will behave the same.

Two radial-equivalent sizes are associated with 560-15. The first is 155R15, which is an equivalent 80-series metric radial. The second is 560R15, which is a bias-look radial equivalent intended to retain a more traditional visual style while using radial construction.

Those options give the 1961 Singer Gazelle owner two different paths: a Euro-metric radial format or a radial that keeps a vintage-style appearance. The recommended rim-width range for these equivalents is 4 to 5 inches. Even with the same 15-inch wheel diameter, the final choice should be checked against the actual wheel, the car’s clearance, and the overall dimensions being introduced.

That depends on how the 1961 Singer Gazelle is being used and presented. A 560-15 bias-ply tire suits an owner who wants a period-style construction and appearance, while 155R15 gives the car a radial fitment in a size associated with the same 15-inch wheel diameter.

The better choice is usually the one that matches the car’s purpose. Restoration-oriented cars often stay with bias-ply for a more traditional look, while regular road use may lead an owner to consider a radial alternative. Either direction deserves a quick check of wheel width, tire clearance, and the condition of steering and suspension parts before making the change.

Start with the fact that 560-15 is the Gazelle’s bias-ply fitment, then narrow the choice by sidewall style, brand, and intended appearance. Firestone, US Royal, Coker Classic, and Pro-Trac all appear in this size, and the available styles include blackwall, narrow whitewall, and wide whitewall.

The right pick depends on how the car is being presented and driven. A traditional restoration-oriented car may call for a classic bias-ply look, while another owner may simply want a clean blackwall presentation on the correct 15-inch fitment. Rim-width compatibility and the tire’s general role on the car should be compared before settling on one specific 560-15 option.

The 1961 Singer Gazelle has several sidewall style choices depending on tire size and construction. In 560-15 bias-ply, available styles include blackwall, narrow whitewall, and wide whitewall. In 155R15 radial, the available products are blackwall tires, which keeps the radial side of the fitment more understated in appearance.

Sidewall style influences the car’s visual character as much as the tire size itself. Whitewalls can push the Gazelle toward a more formal, period-style presentation, while blackwalls usually look simpler and more restrained. The key is to choose a sidewall treatment that matches the intended appearance without losing sight of the underlying fitment requirements for size, construction, and wheel compatibility.

Tires for the 1961 Singer Gazelle are available from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. The radial side of the fitment includes Firestone, Michelin, Avon, and Vredestein in 155R15, while the bias-ply 560-15 size includes Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand is only one part of the decision. The more useful comparison is how each brand’s offering lines up with the desired construction, sidewall style, tire series, and wheel-width requirements. A Gazelle owner choosing between bias-ply and radial tires should first settle the construction direction, then compare the brands that serve that format rather than trying to compare every product at once.

For a period-style 1961 Singer Gazelle, the 560-15 bias-ply size is the natural starting point. It preserves the vintage numeric sizing format and is available in several visual treatments, including blackwall, narrow whitewall, and wide whitewall, which gives the owner room to shape the car’s final presentation.

The best appearance choice depends on the style of restoration being pursued. Some cars look most convincing on a simple blackwall, while others benefit from a whitewall treatment that suits the era. When exact originality matters, the final sidewall and brand decision should be cross-checked against marque references, period photography, or other vehicle-specific historical sources rather than assumed from size alone.

Tire construction changes the visual character of a restored 1961 Singer Gazelle in noticeable ways. A 560-15 bias-ply tire keeps the car in a traditional vintage format, while a 155R15 radial introduces a more modern tire construction even though it stays within the same 15-inch wheel diameter.

For many restorations, that difference matters as much as the tread or sidewall color. Bias-ply tires usually support a more period-style presentation, especially when paired with the available whitewall options, while blackwall radials tend to look more contemporary and road-oriented. A bias-look radial can also be worth considering when the goal is to balance radial construction with a more traditional appearance.

Yes. A 1961 Singer Gazelle that has aftermarket wheels, suspension changes, altered ride height, or body modifications may no longer accept tire choices in the same way as a stock example. Even though both associated sizes use a 15-inch rim, wheel width and available clearance can still change the fitment picture.

That matters most when moving between 560-15 bias-ply and 155R15 radial construction, or when considering a radial equivalent. Modified cars should be checked for steering clearance, fender clearance, and the actual wheel dimensions on the vehicle. It is also wise to inspect whether suspension wear, alignment issues, or brake and steering changes could affect how the new tire sits and operates.

Before driving a 1961 Singer Gazelle on new tires, inspect the wheels for correct diameter and width, make sure the tires are seated properly, and verify there is no interference at the fenders, suspension, or steering components. Tire pressure should also be set appropriately, and the tires should be checked for any obvious shipping or mounting damage.

A collector-era car deserves a broader pre-drive inspection as well. Look at wheel hardware, brake condition, steering play, and suspension wear, since older components can affect how a fresh set of tires behaves on the road. A short local test drive followed by another clearance and pressure check is a smart way to confirm that the Gazelle is ready for regular use.

Collector-car tires on a 1961 Singer Gazelle should be inspected regularly for cracking, flat spotting, bulges, cuts, uneven wear, and slow air loss. That applies whether the car is running 560-15 bias-ply tires or 155R15 radials. Cars that spend long periods parked need extra attention because age and storage conditions matter as much as mileage.

Proper storage helps preserve both appearance and service life. Keep the Gazelle away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or generators, and check pressure before each outing rather than assuming it has held. Low-use collector cars should also have their tires inspected by condition and age, not just by remaining tread depth.
