1957 Austin A 35 Tires

The 1957 Austin A 35 uses two primary tire sizes: 520-13 in bias-ply construction and 145R13 in radial construction. Both sizes are associated with the A 35 and both use a 13-inch rim, so the main difference is not wheel diameter but the tire format and construction style.

That means the real choice is whether the car should stay with a traditional numeric bias-ply tire or use the narrow Euro-metric radial option. Before selecting either one, confirm the wheel diameter and take a close look at the car's current wheel width and overall setup, especially if the car has been altered from stock over the years.

The tire sizes associated with the 1957 Austin A 35 use a 13-inch rim diameter. That applies to both the 520-13 bias-ply size and the 145R13 radial size, so rim diameter stays consistent even though the construction and sizing system change.

Rim diameter is only part of the fitment picture on a small car like the A 35. Wheel width still matters, particularly when comparing a vintage bias-ply setup with radial alternatives, so it is smart to confirm the actual wheel dimensions on the car before choosing between the available tire families.

Yes. The 1957 Austin A 35 Base uses the same core fitment choices as the model overall, with 520-13 bias-ply and 145R13 radial sizes both associated with the car. In practical terms, the Base model does not introduce a separate wheel diameter or a unique tire-size family.

That keeps the selection process simpler, but it does not remove the need to inspect the individual car. An older A 35 may have replacement wheels or a non-original stance, so the most useful next step is confirming what is actually mounted now before moving into sidewall style, brand, or radial-equivalent decisions.

520-13 is a bias-ply tire size on the 1957 Austin A 35. It uses the vintage numeric bias-ply sizing system, where the 5.20 designation refers to nominal section width and the 13 identifies the rim diameter, making it the traditional construction choice among the A 35's primary fitments.

Choosing 520-13 keeps the car in a period-style construction and opens up blackwall, narrow whitewall, and wide whitewall appearance options. A move away from that size family should be approached carefully, with attention to wheel width, overall tire dimensions, and the amount of room available in the wheelwell and steering range.

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. Those three sizes give the 1957 Austin A 35 owner several radial-format alternatives while staying in the same general fitment conversation.

Each equivalent uses a different sizing convention, so the decision is not only about construction but also about profile family and wheel compatibility. A recommended rim-width range of 4 to 5 inches applies here, and the final choice should still be checked against the car's actual wheel width, tire clearance, and intended use.

Start by confirming the wheel diameter, wheel width, and the exact size you plan to use, since the 1957 Austin A 35 can be found with both 520-13 bias-ply and radial-format alternatives. The car should also be checked for enough clearance at the fenders and through the steering range before a radial conversion is treated as workable.

Construction changes can alter the overall character of a small vintage car, so the decision should match how the A 35 will actually be driven. It also helps to inspect suspension wear, alignment condition, and the age of any existing wheels, since those details become more important once the car is asked to run on a different tire type.

Begin with the two correct size families for the 1957 Austin A 35: 520-13 in bias-ply form and 145R13 in radial form. From there, the main decision becomes construction, because both use 13-inch rims but they deliver a different ownership experience in terms of appearance, period character, and the type of tire available.

After construction, compare the details that matter for your car and goals: sidewall style, brand, tire series, and any rim-width guidance attached to the product. A restoration-focused A 35 may lean toward a traditional bias-ply look, while a car meant for regular road use may call for closer evaluation of the radial choices.

Sidewall choices for the 1957 Austin A 35 include blackwall, narrow whitewall, and wide whitewall styles. The 145R13 radial options are blackwall, while the 520-13 bias-ply selection adds both narrow whitewall and wide whitewall presentations for owners who want a more stylized or restoration-oriented look.

That split matters because sidewall style is tied closely to construction in this application. A buyer looking for a cleaner, understated appearance may focus on blackwall, while someone shaping a stronger vintage presentation may prefer one of the whitewall bias-ply options after confirming the tire size and wheel setup on the car.

Tires for the 1957 Austin A 35 are available from Michelin, Firestone, and Premium Sport. Michelin and Firestone appear in the 145R13 radial category, while Firestone and Premium Sport cover the 520-13 bias-ply size with several sidewall treatments and series distinctions.

Brand is only one part of the decision on a car like the A 35. It still makes sense to compare the exact size, construction, sidewall style, and any stated rim-width or load details that come with the individual tire, since those factors do more to shape fitment and overall suitability than brand name alone.

For a period-style 1957 Austin A 35, the 520-13 bias-ply fitment is the most natural starting point because it keeps the car in a vintage numeric size and traditional construction. That choice also opens up blackwall, narrow whitewall, and wide whitewall presentations, which can shape the car's finished look in very different ways.

Appearance goals should be balanced against how closely the car is being restored and how it will be driven afterward. If exact originality matters, compare your tire choice against marque references or period photography, since a correct size alone does not automatically establish the exact brand or sidewall treatment used when the car was new.

Tire construction changes more than ride feel on a restored 1957 Austin A 35; it also changes the visual character of the car. A 520-13 bias-ply preserves a more traditional small-car presentation, while a 145R13 radial gives the car a later-style tire format even though it stays within an appropriate narrow 13-inch size family.

That difference becomes especially noticeable on a compact saloon where the tires are a visible part of the stance. Owners pursuing a restoration-oriented result often start with construction first, then narrow the decision by sidewall style, because the overall look can shift significantly before any brand or series preference even enters the discussion.

Yes. Modifications can change tire fitment on a 1957 Austin A 35 even when the correct tire size is chosen on paper. Aftermarket wheels, altered wheel width, suspension changes, lowering, or bodywork repairs can all affect how a 520-13 or 145R13 tire sits in the wheel opening and how it clears during steering.

A small vintage car has less room to hide fitment changes, so even modest alterations deserve a closer look. Measuring the actual wheel, checking sidewall clearance, and turning the front wheels lock to lock before regular road use can prevent surprises that a catalog size alone will not catch.

Before driving a 1957 Austin A 35 on new tires, inspect the wheels for correct diameter and condition, confirm that the tires are seated properly, and verify that inflation is appropriate for the tire being used. It also helps to look over the steering and suspension for worn parts that could affect how the car tracks.

A short, careful shakedown drive is smart on any collector vehicle after tire installation. During that first outing, pay attention to clearance, unusual rubbing, vibration, and how the car responds at low and moderate speed, then recheck air retention and wheel hardware once the tires have had an initial run.

Collector-car tires on a 1957 Austin A 35 should be maintained with regular pressure checks, routine visual inspection, and clean storage conditions when the car is not being used often. Both 520-13 bias-ply and 145R13 radial tires deserve close attention to cracking, cuts, bulges, uneven wear, and any signs of persistent air loss.

Low annual mileage can hide tire aging, so condition matters at least as much as tread depth on an older Austin. Parking away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber, and periodic inspection becomes even more important if the car spends long stretches sitting between drives.
