The 1961 Austin A 55 sits squarely in the practical British family-car tradition of the early postwar years, with tidy proportions and a straightforward mechanical character that still appeals to collectors who enjoy usable vintage motoring. Tire choice on this car is more nuanced than it first appears, because both a 5.90-14 bias-ply and a 165R14 radial are used on the same 14-inch rim. That gives owners a real decision between traditional bias-ply sizing and a later-style radial format. Available 165R14 options also bring differences in brand and tire series. The right choice depends on whether the goal is period-style presentation, road manners, or a balanced restoration approach.
Which Tire Size Is Right for The 1961 Austin A 55
The 1961 Austin A 55 uses two primary tire sizes, and the difference comes down mainly to construction rather than wheel diameter. Both sizes fit a 14-inch rim, but one is a vintage 5.90-14 bias-ply and the other is a 165R14 radial, so the first step is deciding whether the car should stay with a traditional bias-ply presentation or move to a radial-style setup.
165R14 is a Euro-metric radial size in which 165 refers to the nominal section width in millimeters, R indicates radial construction, and 14 identifies the wheel diameter in inches. On a 1961 Austin A 55, this size represents the radial fitment path while staying on the correct 14-inch rim. Available choices include Pirelli, Michelin, and Vredestein, all in blackwall form, with series such as Cinturato CA67, XAS, and Sprint Classic. It is a useful size to consider when road use, brand preference, and classic radial character matter as much as vintage appearance.
5.90-14 is a numeric bias-ply size, where 5.90 indicates the tire's nominal section width in inches and 14 is the wheel diameter. This format is closely associated with the way many compact and midsize cars of the period were originally equipped, making it the traditional-construction option for the 1961 Austin A 55. Bias-ply sizing also speaks to a different visual and driving character than a radial tire, even though the rim diameter stays the same. It is the size to evaluate when preserving an earlier tire look and construction style is central to the car's presentation.
Sub-model fitment is straightforward here because the covered Austin A 55 configuration uses the same two tire sizes throughout. Checking the exact sub-model still matters, but the main decision is choosing between the 165R14 radial and the 5.90-14 bias-ply on a 14-inch wheel.

1961 Austin A 55 Base
The 1961 Austin A 55 Base uses the same two-size fitment pattern, with 165R14 in radial construction and 5.90-14 in bias-ply construction. That gives the owner a choice between a more traditional period-style tire format and a classic radial setup while keeping the correct 14-inch rim diameter in view.
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 1961 Austin A 55 Tires for Sale

The product grid is where to compare tire series, construction details, rim-width compatibility, weight, and restoration-minded brand character within this radial fitment.
Austin A 55 owners usually want clarity on the two correct tire sizes, the shared 14-inch rim fitment, and how to choose between bias-ply tradition and radial road use. The questions below focus on size meaning, product selection, appearance, and practical checks before driving.
Tire Size & Fitment
What tire size fits a 1961 Austin A 55?
The 1961 Austin A 55 uses two primary tire sizes: 165R14 in radial construction and 5.90-14 in bias-ply construction. Both sizes are associated with the A 55 on a 14-inch wheel, so the fitment question is less about diameter and more about which construction style suits the car and its intended use.
That means the owner should first confirm the wheel diameter is still 14 inches and then decide whether the car is being kept in a more traditional bias-ply format or set up with a classic radial. If the car has replacement wheels or past modifications, checking wheel width and clearance before choosing either size is a smart next step.
What size rim does a 1961 Austin A 55 use?
The 1961 Austin A 55 uses a 14-inch rim with both of its supported tire sizes. That shared rim diameter is one reason the tire decision centers on the difference between the 5.90-14 bias-ply and the 165R14 radial rather than on changing wheel diameter from one setup to the other.
Rim diameter is only part of the picture, though. Before mounting a tire, it still helps to verify the actual wheel width and inspect the car for aftermarket wheels, brake changes, or suspension work that could affect clearance. A 14-inch wheel is the starting point, but the full wheel and vehicle setup should still be confirmed.
Does the 1961 Austin A 55 Base use the same tire size?
Yes. The 1961 Austin A 55 Base uses the same tire fitment pattern, with both 165R14 radial and 5.90-14 bias-ply sizes associated with it. That makes sub-model identification straightforward here, because the real choice is not between different Base-only sizes but between two different tire construction approaches.
For the owner, that means the next decision is about how the car should look and drive rather than whether the Base requires a separate wheel diameter. A period-style restoration may keep attention on the bias-ply size, while a road-oriented setup may lead toward the 165R14 radial, provided the wheel and clearance setup are still appropriate.
Bias-Ply & Radial Options
Is 5.90-14 a bias-ply or radial tire for the 1961 Austin A 55?
5.90-14 is the bias-ply tire size used on the 1961 Austin A 55. It is a vintage numeric size format, with 5.90 describing the nominal section width and 14 indicating the wheel diameter, and it represents the traditional-construction option for this car rather than a radial fitment.
That matters because a bias-ply tire affects both the car's appearance and the way the tire presents on the wheel compared with a radial alternative like 165R14. Anyone moving away from 5.90-14 should confirm wheel dimensions and vehicle clearance rather than assume that sharing a 14-inch rim automatically makes every alternative equivalent in practice.
Should I use bias-ply or radial tires on a 1961 Austin A 55?
The 1961 Austin A 55 can be set up with either a 5.90-14 bias-ply or a 165R14 radial, so the choice depends on the goal for the car. Bias-ply keeps the tire format rooted in vintage practice, while 165R14 represents the radial route on the same 14-inch rim diameter.
A restoration-minded owner may lean toward the bias-ply size for a more traditional presentation, while a driver who plans regular road use may prefer to evaluate the radial options available in 165R14. Either way, the decision should include a check of wheel width, clearance, and the car's current setup instead of focusing on size code alone.
What should I check before converting my 1961 Austin A 55 from bias-ply to radial tires?
A conversion from the 5.90-14 bias-ply size to the 165R14 radial starts with confirming that the car still has the correct 14-inch wheels and that the wheel width suits the radial being considered. It also helps to inspect suspension condition and steering components, since older collector cars often have age-related wear that becomes more noticeable with new tires.
Clearance should be checked at the fenders and through the steering range, especially if the car has replacement wheels or any chassis changes. The owner should also compare the selected radial's specifications carefully rather than treating it as an automatic substitute, because construction changes can alter how a tire works with the car even on the same rim diameter.
Choosing the Right Tire
What should I consider when choosing a tire for a 1961 Austin A 55?
Start with the correct size and construction choice: 5.90-14 for bias-ply or 165R14 for radial. From there, selection should focus on the car's intended role, whether that is a more traditional presentation, regular road use, or a compromise between vintage appearance and practical drivability on a 14-inch wheel.
Once the construction decision is made, compare details that actually affect the setup, such as wheel compatibility, load figures where available, and the visual character of the tire. On this car, choosing carefully matters more than simply picking any tire with a matching diameter, especially if the wheels, suspension, or ride height have changed over time.
What brands offer tires for the 1961 Austin A 55?
The 165R14 radial fitment for the 1961 Austin A 55 is available from Pirelli, Michelin, and Vredestein. Those brands appear in classic radial offerings that stay within the proper 14-inch format while giving the owner a choice among different long-established tire lines aimed at vintage and collector vehicles.
Brand choice should be considered alongside tire series, construction, and wheel compatibility rather than as a stand-alone decision. Since the available 165R14 products are all blackwall radials, the comparison becomes more about the character of each classic tire line and whether the chosen tire matches the car's use, wheel dimensions, and restoration priorities.
What tire series are available for the 1961 Austin A 55?
In the 165R14 radial size, the 1961 Austin A 55 has access to the Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic series. Those series give the owner distinct classic-tire choices within the same general radial fitment rather than forcing the decision down to size alone.
Comparing series is useful because it helps narrow the tire by intended character and specification details, including wheel-width guidance where available and overall product presentation. The smartest approach is to keep the series comparison grounded in the correct size and wheel setup first, then use brand and series differences to refine the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 1961 Austin A 55?
For a period-style 1961 Austin A 55, the 5.90-14 bias-ply size is the most natural starting point because it preserves the vintage numeric sizing format and traditional construction associated with the era. That makes it especially relevant when the goal is to maintain an older visual character rather than move the car toward a later radial-style presentation.
Owners pursuing a highly exact restoration should still confirm details through marque references, period photography, or other vehicle-specific documentation before treating any one tire as exact-original. For many collector cars, though, staying with the proper bias-ply size is the clearest way to support a restoration-oriented appearance while keeping the wheel diameter correct.
How does tire construction affect the appearance of a restored 1961 Austin A 55?
Tire construction changes the visual tone of a restored 1961 Austin A 55 even when the wheel diameter remains 14 inches. A 5.90-14 bias-ply keeps the car in a more traditional vintage sizing language, while a 165R14 radial introduces a later-style metric format that can subtly change how the tire looks in relation to the body and wheel.
That does not make one choice universally right. A restoration focused on period-style presentation may favor the bias-ply route, while a driver-restoration may accept the radial appearance in exchange for a different ownership experience. Looking at the tire on the actual wheel, and in the context of the car's trim and stance, helps settle the decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1961 Austin A 55?
Yes, modifications can affect tire fitment on a 1961 Austin A 55 even when the nominal tire size appears correct. Aftermarket wheels, suspension alterations, brake changes, or bodywork repairs can all influence how a 5.90-14 bias-ply or 165R14 radial sits within the wheel opening and how much clearance remains during steering and suspension movement.
That is why the actual car should be checked before settling on a tire choice. Wheel diameter is only one part of fitment, and older cars often carry changes made over decades of use. Measuring the current wheels and inspecting for rubbing points is a far safer approach than assuming every A 55 still matches its original wheel and suspension setup.
What should I inspect before driving a 1961 Austin A 55 on new tires?
Before driving a 1961 Austin A 55 on new tires, inspect the wheels for damage or corrosion, confirm the tires are seated properly, and verify inflation is set appropriately for the chosen tire. It also makes sense to check steering joints, suspension bushings, and wheel bearings, since worn front-end parts can quickly affect how a fresh set of tires behaves.
A short local test drive is a smart first step before longer use. During that drive, watch for vibration, pulling, rubbing, or uneven clearance when turning. Rechecking air pressure and visually inspecting the sidewalls and tread after the first miles can catch setup issues early, especially on a collector car that may have spent long periods parked.
How should tires on a collector 1961 Austin A 55 be maintained?
Tires on a collector 1961 Austin A 55 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Low-use vintage cars can age tires long before they wear them out, so sidewall cracking, bulges, cuts, and gradual air loss deserve just as much attention as tread condition on either the 5.90-14 bias-ply or 165R14 radial setup.
Storage matters almost as much as road use. Keeping the car away from prolonged sunlight, standing moisture, and ozone-producing equipment helps protect the tires over time, and moving the vehicle periodically can reduce prolonged flat spotting. A quick inspection before each drive is worthwhile because collector cars often spend enough time parked for small problems to grow unnoticed.
