1957 Singer Gazelle Tires

The 1957 Singer Gazelle uses two established tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both fitment paths use a 15-inch rim, so the size decision is tied closely to the type of tire construction and the look you want the car to have.

That means the first step is deciding whether the Gazelle is staying with a traditional bias-ply setup or moving to a radial-format tire. After that, confirm the actual wheel width on the car, especially if the wheels have been changed over the years, because rim-width compatibility can vary between the available products.

The 1957 Singer Gazelle uses a 15-inch rim with both of its recognized tire sizes. The bias-ply 560-15 and the radial 155R15 are both built around that same 15-inch wheel diameter, which simplifies the basic wheel-size question for most owners.

Even with the same diameter, wheel width still matters before selecting a tire. A radial and a bias-ply in these sizes may not share the same recommended rim-width range, so it is smart to measure the wheel already on the car and verify that it matches the specifications of the tire style being considered.

The 1957 Singer Gazelle Base can use the same two tire sizes associated with this model: 560-15 as a bias-ply option and 155R15 as a radial option. The fitment is not split into different Base-specific sizes, so the decision centers on construction and tire type rather than trim variation.

That makes selection more straightforward, but it does not remove the need to inspect the car itself. A Gazelle that has different wheels, altered suspension height, or long-ago replacement rims may need closer checking before changing from one construction type to the other, even though the basic 15-inch diameter remains the same.

560-15 is the bias-ply tire size used on the 1957 Singer Gazelle. It is the traditional numeric sizing format for the car and represents the more period-appropriate construction if the goal is to keep a distinctly mid-1950s tire appearance and character.

Bias-ply selection within 560-15 still leaves room for different looks, including blackwall, narrow whitewall, and wide whitewall styles. Since the Gazelle can also use a radial alternative, the practical question is whether the car is being kept closer to its original-era presentation or being set up for a different road-use preference.

Radial equivalents for 560-15 include 155R15 and 560R15. The 155R15 size is an 80-series metric radial equivalent, while 560R15 is a bias-look radial equivalent intended to preserve a more traditional visual profile than a modern-looking radial size might.

Those options should be treated as alternatives, not automatic substitutions. A recommended rim-width range of 4 to 5 inches applies to the equivalent setup, and the car's wheel width, overall tire dimensions, and body or steering clearance should all be checked before replacing a 560-15 bias-ply with a radial construction tire.

A 560R15 bias-look radial can be considered for a 1957 Singer Gazelle as the radial equivalent tied to the original 560-15 bias-ply size. Its role is to offer radial construction while keeping a more traditional appearance than a purely modern radial sizing presentation.

That makes it especially relevant for owners who want to soften the visual change that often comes with a radial conversion. It is still important to confirm wheel width, tire clearance, and the condition of the suspension and steering components so the conversion works with the car's actual setup rather than just the nominal tire size.

Start with the two approved fitment paths for the 1957 Singer Gazelle: 560-15 in bias-ply construction or 155R15 in radial construction. That choice shapes nearly everything else, including the car's visual presentation, the available brands and tire series, and whether sidewall styling becomes part of the decision.

After settling on construction, compare the product details that actually affect use on your car, such as rim-width compatibility, sidewall treatment, and load figures where stated. A Gazelle used mainly for restoration display may point one way, while a car intended for regular road miles may lead you to evaluate the radial-format choices more closely.

Sidewall choices for the 1957 Singer Gazelle vary by tire size and construction. The 155R15 radial options are blackwall, while the 560-15 bias-ply options include blackwall, narrow whitewall, and wide whitewall styles depending on the brand and series selected.

That gives the Gazelle owner a real appearance decision beyond simple fitment. A blackwall usually creates a more restrained presentation, while whitewall widths can shift the car toward a more overt period-style look. Choosing among them comes down to how the car is restored, how original-looking you want it to appear, and which construction you plan to use.

The 1957 Singer Gazelle has tire options from several brands across its two fitment sizes. Radial choices in 155R15 include Firestone, Michelin, Avon, and Vredestein, while bias-ply 560-15 options include Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand alone should not be the only filter. It helps more to compare each tire's size, construction, sidewall style, and series character within the kind of Gazelle you want to build or drive. That approach keeps the decision focused on fitment and presentation instead of assuming every tire in the same diameter serves the same purpose.

For a period-style 1957 Singer Gazelle, the 560-15 bias-ply size is the natural starting point because it matches the car's traditional tire format and opens the door to blackwall, narrow whitewall, or wide whitewall presentation. That combination usually aligns better with a mid-1950s visual character than a modern radial-format appearance.

The final choice depends on how closely the car is being restored and what look suits its trim and stance. If exact originality matters, confirm period appearance details through marque references or historical photos. If the goal is simply the right overall impression, the available 560-15 bias-ply styles provide several restoration-oriented directions.

Tire construction changes the appearance of a restored 1957 Singer Gazelle more than many owners expect. A 560-15 bias-ply gives the car a more traditional visual stance and sidewall profile, while a 155R15 radial introduces a later-style sizing format and a cleaner blackwall-only presentation among the available choices.

That difference matters because tires sit at the edge of every exterior view of the car. Owners who want the Gazelle to read as distinctly 1950s often lean toward the bias-ply route, while those prioritizing a radial setup may accept the visual shift. The right answer depends on whether restoration appearance or updated construction carries more weight.

Modifications can absolutely affect tire fitment on a 1957 Singer Gazelle, even when the tire size itself is appropriate. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs around the fender openings can all influence how a 560-15 or 155R15 tire sits and clears.

That is why the actual car should be checked before settling on a tire, especially when changing from bias-ply to radial construction. Wheel diameter may remain 15 inches, but steering clearance, sidewall room, and wheel-width suitability can still vary enough to matter once the vehicle has drifted from its original wheel and suspension setup.

Before driving a 1957 Singer Gazelle on new tires, inspect the wheels for the correct 15-inch diameter, verify wheel condition, and make sure the selected tire matches the wheel width being used. It is also smart to look over the steering and suspension so worn components do not mask themselves as a tire problem.

A close walkaround should include checking for adequate fender and steering clearance at full lock and through suspension movement. Once the tires are installed, monitor inflation pressure, bead seating, and any signs of rubbing or uneven wear during the first miles, because early inspection often catches fitment issues before they become expensive.

Tires on a collector 1957 Singer Gazelle should be inspected regularly for air loss, cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low annual mileage does not stop rubber from aging, so visual condition matters just as much as tread depth on an older collector vehicle.

Storage conditions also play a big part in tire life. Keeping the Gazelle away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve both bias-ply and radial tires. Periodic pressure checks and short test drives can reveal early issues, especially after seasonal storage or long stretches when the car has not been used.
