The 1959 Austin A 55 sits in the practical heart of postwar British motoring, a family saloon remembered for tidy proportions, straightforward engineering, and the kind of road manners that reward keeping the chassis and tire setup in balance. For this exact model year, the tire decision centers on two 14-inch fitments: a 5.90-14 bias-ply size and a 165R14 radial. That gives owners a meaningful choice between a more traditional construction and a later-style radial format. The right direction depends on whether the goal is a period-style presentation, more modern road use, or a careful blend of appearance and drivability.
Which Tire Size Is Right for The 1959 Austin A 55
The 1959 Austin A 55 uses two primary tire sizes, both on 14-inch rims: 5.90-14 in bias-ply construction and 165R14 in radial construction. Since the Base sub-model uses both fitments, the real decision is not sub-model identification but deciding which construction and tire character best suits the car's wheels, appearance goals, and intended road use.
165R14 is a Euro-metric radial size, with 165 representing the nominal section width in millimeters, R indicating radial construction, and 14 identifying the wheel diameter in inches. On a 1959 Austin A 55, this size reflects a radial fitment path that keeps the car on its correct 14-inch rim diameter. Available choices include blackwall offerings from Pirelli, Michelin, and Vredestein in series such as Cinturato CA67, Michelin XAS, and Sprint Classic. It is a strong size to evaluate when preserving a classic European radial look matters as much as road use and wheel compatibility.
5.90-14 is a numeric bias-ply size, with 5.90 indicating the nominal section width in inches and 14 identifying the wheel diameter. For the 1959 Austin A 55, it represents the traditional bias-ply construction choice and the more vintage sizing convention associated with many cars of this era. Bias-ply fitments are often considered by owners who want a more period-style stance and presentation on a 14-inch wheel. This size is worth considering when maintaining an earlier driving feel and visual character is more important than moving to a radial-format alternative.
Tire fitment is straightforward for the covered 1959 Austin A 55 sub-model. The Base model uses the same two 14-inch fitment paths, so the key choice is construction type rather than trimming the search by sub-model.

1959 Austin A 55 Base
The 1959 Austin A 55 Base uses both the 165R14 radial and the 5.90-14 bias-ply fitments on 14-inch wheels. That means tire selection comes down to whether the car is being kept in a more traditional bias-ply presentation or fitted with a classic radial option for its intended use.
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 1959 Austin A 55 Tires for Sale
Available 165R14 options for the 1959 Austin A 55 focus on blackwall radial choices from Pirelli, Michelin, and Vredestein. The main differences in the product grid are tire series, radial construction details, and rim-width compatibility where that specification is stated.
Owners of a 1959 Austin A 55 usually want clarity on the two 14-inch tire fitments, how bias-ply and radial choices differ, and what to inspect before putting a lightly used collector car back on the road.
Tire Size & Fitment
What tire size fits a 1959 Austin A 55?
A 1959 Austin A 55 uses two primary tire sizes: 165R14 in radial construction and 5.90-14 in bias-ply construction. Both sizes are 14-inch fitments, so the choice is not about changing wheel diameter but about selecting the tire format and construction that best matches the car and its intended use.
The practical next step is confirming which setup is already on the car and whether the wheels are suited to that construction. A restored car may favor the traditional look of 5.90-14, while a road-driven example may be using 165R14 radials. Wheel width, overall clearance, and any prior modifications should be checked before changing from one type to the other.
What size rim does a 1959 Austin A 55 use?
The 1959 Austin A 55 uses a 14-inch rim diameter with both of its primary tire fitments. That applies to the 165R14 radial size and the 5.90-14 bias-ply size, so the wheel diameter remains consistent even though the sizing systems and constructions are different.
That consistency makes wheel-diameter confirmation simpler, but it does not mean every 14-inch wheel is automatically suitable for either tire. Rim width still matters, especially when considering radial options, and an older car may have replacement wheels installed. Checking the wheel stamping or measuring the wheel before ordering helps avoid problems with profile, bead seating, or clearance.
Does the 1959 Austin A 55 Base use the same tire size?
Yes. The 1959 Austin A 55 Base is associated with the same two primary fitments used on this model year: 165R14 radial and 5.90-14 bias-ply. That means sub-model identification is straightforward here, because the tire decision does not change between covered trims.
What still matters is identifying which construction you want to run on the car now. A Base model being kept close to an earlier period-style presentation may lead toward the bias-ply size, while a car used more regularly may be fitted with a radial. Looking at the existing wheels, suspension condition, and tire age can help narrow the right direction.
Choosing the Right Tire
What should I consider when choosing a tire for a 1959 Austin A 55?
Start with the two correct fitment paths for the 1959 Austin A 55: 5.90-14 bias-ply or 165R14 radial, both on 14-inch rims. The main decision is whether the car should keep a more traditional bias-ply setup or use a classic radial format, then compare tire construction, wheel compatibility, and the type of driving the car actually sees.
Once the size path is settled, the finer points become appearance and specification. A road-driven car may benefit from a well-matched radial setup, while a restoration-oriented car may prioritize a more vintage visual character. It also helps to compare stated rim-width guidance, load figures where available, and whether the wheels on the car are original-style or later replacements.
What sidewall styles are available for 1959 Austin A 55 tires?
The currently available 165R14 product assortment for the 1959 Austin A 55 uses blackwall sidewalls. Those options include classic European-style radial offerings, so the visible appearance is fairly consistent across the available products even though the brands and tire series differ.
That makes sidewall choice simpler, but it puts more emphasis on selecting the right construction and series for the car. If appearance is the main goal, look closely at tread style and overall tire profile in addition to the sidewall itself. Buyers considering the 5.90-14 bias-ply route should also confirm the visual result they want before making the switch.
What brands offer tires for the 1959 Austin A 55?
For the 165R14 radial size used on the 1959 Austin A 55, available brands include Pirelli, Michelin, and Vredestein. Those options appear in well-known classic radial series such as Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic.
Brand choice should be treated as one part of the decision rather than the whole decision. It still makes sense to compare the tire series, confirm the rim-width range where it is stated, and think about how the car will be used. An Austin A 55 that spends most of its time in shows may be approached differently than one that sees regular secondary-road driving.
Restoration & Appearance
Which tire should I choose for a period-style 1959 Austin A 55?
For a period-style 1959 Austin A 55, the 5.90-14 bias-ply size is the natural starting point because it preserves the older numeric sizing format and traditional construction associated with many cars of the era. The 165R14 radial remains a valid fitment path, but it presents the car through a more modernized classic-tire lens.
The right answer depends on what kind of restoration is being pursued. A driver-focused car may justify the radial path, while a display-oriented or historically styled build may lean toward the bias-ply presentation. When exact originality matters, it is smart to compare the tire choice against marque-club guidance, period photos, and vehicle-specific historical references.
How does tire construction affect the appearance of a restored 1959 Austin A 55?
Tire construction changes more than the way a 1959 Austin A 55 drives; it also affects how the car sits and reads visually. A 5.90-14 bias-ply gives the car a more traditional vintage impression, while a 165R14 radial brings in a later-style classic radial appearance, even though both fit the same 14-inch wheel diameter.
That visual difference can matter on a restored British saloon where proportions are a big part of the car's character. Buyers often notice sidewall shape, tread presentation, and the overall relationship between the tire and the wheel opening. Choosing with the finished look in mind helps avoid ending up with a setup that is mechanically suitable but aesthetically out of step.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1959 Austin A 55?
Yes. Even though the 1959 Austin A 55 uses 14-inch tire fitments, changes to wheels, suspension height, steering components, or body clearances can affect whether a chosen tire setup works well on the car. That applies whether the car remains on 5.90-14 bias-ply tires or has been set up around 165R14 radials.
A car with aftermarket wheels should be checked for actual rim width and offset before changing tire type. Clearance at the fenders and steering lock deserves attention too, especially on older restorations that may not be perfectly symmetrical. Verifying the setup on the car is more reliable than assuming that every Austin A 55 is still configured the same way.
What should I inspect before driving a 1959 Austin A 55 on new tires?
Before driving a 1959 Austin A 55 on new tires, inspect the wheels for damage, confirm the wheel diameter and condition, and make sure the suspension and steering components are sound. It is also wise to look for rubbing points, uneven ride height, and anything that could affect how either a 5.90-14 bias-ply or 165R14 radial sits on the car.
Tire condition checks should continue after installation. Watch for air loss, visible sidewall distress, unusual wear, and signs that the car is out of alignment. Older collector vehicles often reveal long-hidden issues only after fresh tires are fitted, so a short initial road test followed by a second inspection can prevent a small problem from becoming a larger one.
How should tires on a collector 1959 Austin A 55 be maintained?
Tires on a collector 1959 Austin A 55 should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread depth. Cars that are driven infrequently can still develop sidewall cracking, flat spotting, or air loss, whether they are running traditional bias-ply tires or classic radial tires.
Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber over time. It also pays to inspect the tires before every meaningful outing, since a lightly used Austin may spend long periods parked and can hide deterioration that is not obvious until closer examination.
