1958 Austin A 35 Tires

The 1958 Austin A 35 uses two primary tire sizes: 520-13 in bias-ply construction and 145R13 in radial construction. Both sizes are tied to a 13-inch rim, but they represent different tire formats and different approaches to how the car looks and drives.

Choosing between them starts with the wheel and the purpose of the car. A period-style restoration often points buyers toward the 520-13 bias-ply size, while regular road use may lead them to consider the 145R13 radial. On any A 35 with replacement wheels or past modifications, confirm actual wheel width and clearance before settling on either size.

The tire fitments associated with the 1958 Austin A 35 use a 13-inch rim diameter. Both the 520-13 bias-ply size and the 145R13 radial size are built around that same 13-inch wheel diameter, which keeps rim diameter simple even though construction choices differ.

Rim diameter is only one part of the fitment picture. Wheel width should also be checked, especially if the car has been changed from stock-style wheels or if a radial conversion is being considered. A 13-inch wheel that is too narrow, too wide, or shaped differently at the bead can affect how the tire seats and how the car behaves on the road.

The 1958 Austin A 35 Base is associated with the same two primary tire sizes used for this model: 520-13 in bias-ply construction and 145R13 in radial construction. That means the Base does not introduce a separate rim diameter or a unique tire size requirement of its own.

The practical choice still comes down to how the individual car is equipped and how it will be driven. An owner keeping the car visually close to its period presentation may stay with the numeric bias-ply size, while someone favoring radial construction may move toward 145R13. Any car with aftermarket wheels should have the wheel width checked before the final decision.

On the 1958 Austin A 35, 520-13 is a bias-ply tire size. It uses the older numeric sizing format common to many small cars of the era, with 5.20 representing nominal section width in inches and 13 representing the rim diameter.

That matters because a bias-ply tire affects both appearance and tire behavior compared with a radial. Buyers considering 520-13 should focus on period-style presentation, available sidewall treatments, and whether the car is being restored or simply driven casually. If the goal is to switch to a radial alternative, it is better to review the available equivalent sizes and confirm wheel compatibility first.

Radial equivalents for 520-13 include 155R13 as an 80-series metric radial, P155/75R13 as a P-metric 75-series radial, and P155/70R13 as a P-metric 70-series radial. These are alternative radial sizing formats related to the original bias-ply size rather than additional primary factory-style fitments.

Each of those sizes should be checked against the car's actual wheel and body setup before conversion. A recommended rim-width range of 4 to 5 inches applies to those equivalents, which makes wheel width especially important. The buyer should also compare overall dimensions, steering clearance, and the intended use of the Austin before selecting one radial format over another.

Start by confirming the wheel diameter and actual wheel width on the car, since the 1958 Austin A 35 uses 13-inch tires but radial equivalents for 520-13 carry their own rim-width considerations. The available radial alternatives include 155R13, P155/75R13, and P155/70R13, and each should be treated as an option to evaluate rather than an automatic swap.

Clearance at the fenders, steering components, and suspension should be checked with the car at normal ride height. It also helps to inspect the general condition of the front end, because an older vehicle can react differently once tire construction changes. Keeping all four tires matched in size and construction is usually the cleanest path for predictable road manners.

A 520-13 tire for a 1958 Austin A 35 should be chosen first by confirming that a bias-ply tire is the intended direction. From there, the main considerations are sidewall style, tire series, and wheel compatibility, since this size is available in blackwall, narrow whitewall, and wide whitewall versions.

Appearance plays a major role in this size because the sidewall treatment strongly affects how the car presents. Firestone Classic Bias Ply and Premium Sport Lowrider options create different visual impressions even though they share the same basic size. Rim width and load specifications can also differ by product, so those details deserve a close look before making a final selection.

The 1958 Austin A 35 has tire options in several sidewall styles, including blackwall, narrow whitewall, and wide whitewall. Blackwall appears in both radial and bias-ply offerings, while the whitewall choices are tied to the 520-13 bias-ply products.

That gives the buyer a meaningful appearance decision beyond simple size and construction. A blackwall keeps the presentation understated and traditional, while narrow and wide whitewalls move the car toward a more stylized vintage look. Since sidewall style does not change the need for proper fitment, confirm the correct size and wheel dimensions first, then choose the look that best suits the car.

Tires for the 1958 Austin A 35 are available from Michelin, Firestone, and Premium Sport. Michelin and Firestone cover the radial side in 145R13, while Firestone and Premium Sport provide the bias-ply 520-13 choices with different sidewall treatments and series names.

Brand choice should be considered alongside construction type and visual goals rather than as a standalone decision. A buyer comparing these options should look at whether the tire is radial or bias-ply, what sidewall style it carries, and whether the rim-width and load details match the car's needs. That approach leads to a better decision than choosing on brand name alone.

For a period-style 1958 Austin A 35, the 520-13 bias-ply tire is the natural starting point because it preserves the vintage numeric size format and traditional construction associated with small cars of the era. It is also available in blackwall, narrow whitewall, and wide whitewall styles, which helps shape the finished look.

The right version depends on whether the goal is a restrained restoration-oriented appearance or something more visually accented. Buyers seeking exact historical authenticity should compare their choice against marque references, period photos, or vehicle-specific documentation rather than assuming one sidewall treatment is universally correct. That extra step matters more than simply matching the size.

Tire construction changes the visual character of a restored 1958 Austin A 35 as much as it changes the driving feel. A 520-13 bias-ply gives the car a more traditional presentation through its older sizing format and period-style profile, while a 145R13 radial introduces a more modern tire look even though it still fits a 13-inch rim.

That difference becomes especially noticeable on a small British car where the tire is a visible part of the stance. Buyers who value a restoration-oriented appearance often begin with the bias-ply size, then choose between blackwall and whitewall treatments. Owners prioritizing regular road use may still prefer a radial, but should understand that the visual result will be different.

Yes, modifications can affect tire fitment on a 1958 Austin A 35 even when the car still uses a 13-inch wheel. Aftermarket wheels, different wheel widths, suspension changes, ride-height adjustments, or body alterations can all change how a 520-13 bias-ply or 145R13 radial sits in the wheel opening.

A car that has been altered should be checked for steering clearance, fender clearance, and wheel width before a tire is chosen. That matters even more when moving from the original-style bias-ply size toward a radial or a radial equivalent. Looking at the actual vehicle setup prevents assuming that a nominally correct size will behave the same on every A 35.

Before driving a 1958 Austin A 35 on new tires, inspect the wheels for damage or corrosion, confirm that the tire size matches the intended setup, and check that all four tires are inflated properly. It is also wise to look over steering and suspension condition so the new tires are not masking loose or worn components.

A short, careful test drive is the best next step after installation. Listen for rubbing, feel for unusual pull or vibration, and recheck air pressure once the tires have settled. Collector cars that spend long periods parked also deserve a quick inspection for fluid leaks, brake drag, and bearing issues, since those problems can affect how the new tires wear.

520-13 tires on a collector 1958 Austin A 35 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires deserve close attention for sidewall cracking, cuts, bulges, uneven wear, and signs of air loss, especially on a car that is driven infrequently or stored for long periods.

Keeping the car away from prolonged sunlight, moisture, excess heat, and ozone sources helps preserve the rubber. It also helps to move the car periodically or avoid letting it sit on one spot for too long. Before any longer drive, inspect tread and sidewalls closely and verify that the tires still suit the car's current wheel and suspension setup.
