The 1966 Austin A 110 comes from the era when British saloons balanced formal styling, roomy accommodations, and smooth road manners with practical everyday use. As part of Austin’s larger family-car tradition, the A 110 still appeals to owners who value a distinctly mid-century British look and feel. Tire selection for this car starts with one primary fitment, a 7.50-13 bias-ply on a 13-inch rim, which keeps the vehicle in its proper vintage sizing language. The focus is less about choosing between multiple fitment sizes and more about preserving period-style character while confirming wheel condition, overall compatibility, and readiness for regular road use.
Which Tire Size Is Right for The 1966 Austin A 110
The 1966 Austin A 110 uses one primary tire size: 7.50-13, a bias-ply fitment for a 13-inch rim. On this car, the key decision is not sorting through multiple factory fitments, but choosing a tire that preserves the right vintage look and construction while also matching the actual wheel setup and the car’s intended road use.
The 7.50-13 size uses the older numeric bias-ply system, where 7.50 refers to the tire’s nominal section width in inches and 13 refers to the wheel diameter in inches. On a 1966 Austin A 110, that means a traditional bias-ply construction that suits the car’s original-era tire format and overall appearance. Buyers familiar only with modern metric radials will notice that this is a vintage sizing convention rather than a current passenger-car designation. Choosing this size keeps the tire selection centered on proper period-style fitment, wheel compatibility, and the driving character expected from a classic British saloon.
Fitment is straightforward for the covered 1966 Austin A 110 sub-models. The Westminster uses the same primary tire size, so the main task is confirming the actual wheel and selecting the right bias-ply tire for the car’s condition and intended use.

Frequently Asked Questions
Owners of a 1966 Austin A 110 usually want clear answers on 7.50-13 fitment, 13-inch wheel compatibility, bias-ply construction, restoration-minded tire choice, and the checks that matter before putting a vintage saloon back on the road.
Tire Size & Fitment
What tire size fits a 1966 Austin A 110?
The 1966 Austin A 110 uses a 7.50-13 tire size. This is a bias-ply fitment in a vintage numeric sizing format, and it is the primary size associated with the car.
That means the first step is confirming that the car still has the correct 13-inch wheels and has not been changed to another wheel and tire package over the years. On a collector vehicle, actual wheel condition, body clearance, and any past modifications matter just as much as the size printed on the sidewall.
What size rim does a 1966 Austin A 110 use?
The 1966 Austin A 110 uses a 13-inch rim with its 7.50-13 tire fitment. The wheel diameter is an important part of the tire size, so a 13-inch tire belongs on a 13-inch wheel.
Wheel diameter should be confirmed before ordering replacement tires, especially on older cars that may have had wheels swapped at some point in their lives. It is also wise to inspect the wheel itself for rust, damage, or bead-seat issues before mounting new tires on a vintage Austin.
What does 7.50-13 mean on a 1966 Austin A 110?
A 7.50-13 tire uses a vintage numeric bias-ply size format. The 7.50 refers to the tire’s nominal section width in inches, while 13 refers to the wheel diameter in inches.
This older numbering system differs from modern metric radial sizes, so it helps to treat it as its own fitment language rather than trying to compare it casually to newer passenger-car sizes. For the Austin A 110, keeping that format in mind helps preserve the proper vintage look and avoids confusion when selecting replacement tires.
Choosing the Right Tire
What should I consider when choosing a 7.50-13 tire for a 1966 Austin A 110?
Start with the correct primary size and construction: 7.50-13 in bias-ply form. On a 1966 Austin A 110, that keeps the selection aligned with the car’s original-era tire format and the appearance most owners expect from a mid-1960s British saloon.
After that, attention should shift to the actual wheel condition, the car’s current setup, and how it will be used. A lightly driven show car may place more emphasis on traditional presentation, while a road-driven car still needs proper mounting surfaces, sound suspension, and enough clearance throughout steering and suspension travel.
How do I choose between the available 7.50-13 tires for a 1966 Austin A 110?
When several tires share the same 7.50-13 size, the main comparison points are construction style, appearance, and how closely the tire suits the car’s intended character. For a 1966 Austin A 110, the decision usually centers on maintaining a proper vintage presentation rather than chasing modern sizing trends.
It helps to look beyond the size alone and inspect the rest of the setup before making a final choice. Wheel condition, how the car sits, the state of the steering and suspension, and the kind of use planned for the car all influence which 7.50-13 tire makes the most sense.
Why is the correct tire size so important on a 1966 Austin A 110?
The correct tire size matters because it keeps the 1966 Austin A 110 within the wheel diameter and overall fitment pattern intended for the car. Using the proper 7.50-13 size also preserves the visual proportions that suit a mid-century British saloon.
Moving away from the original-size fitment without careful measurement can create problems with wheel compatibility, clearance, or overall stance. On an older car, even small changes in size format can affect how the tire looks in the wheel opening, so it is worth confirming dimensions and the actual wheel setup before changing course.
Restoration & Appearance
Which tire should I choose for a period-style 1966 Austin A 110?
A period-style approach for a 1966 Austin A 110 starts with the proper 7.50-13 bias-ply fitment. That keeps the car in the vintage size format and construction type that match the era of the Westminster and similar mid-1960s British saloons.
Owners focused on restoration appearance usually want the tire to support the car’s proportions as much as its drivability. Exact originality claims should be checked against marque references, surviving examples, or historical documentation, but staying with the correct numeric bias-ply size is the clearest foundation for a restoration-minded selection.
Does correct tire fitment matter for a 1966 Austin A 110 restoration?
Correct tire fitment matters on a 1966 Austin A 110 because tire size and construction strongly influence how the car sits and how authentic its overall presentation feels. A 7.50-13 bias-ply maintains the vintage fitment language associated with this model.
Restoration work often gives close attention to paint, trim, and interior details, but the wrong tire can change the car’s visual balance immediately. Beyond appearance, proper fitment also helps avoid clearance surprises and wheel mismatches, which is especially important when a restored car returns to regular driving after years of limited use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1966 Austin A 110?
Yes, modifications can affect tire fitment on a 1966 Austin A 110. Changes such as aftermarket wheels, altered ride height, brake conversions, suspension work, or body repairs can all influence how a 7.50-13 tire sits and clears the car.
That is why the actual wheel diameter and overall setup should be checked before replacing tires on any older Austin. Even when the car is supposed to use the standard 13-inch fitment, clearance at full steering lock and through suspension movement is worth confirming on a vehicle that may have changed over time.
What should I inspect before driving a 1966 Austin A 110 on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and the general condition of the steering and suspension. It also makes sense to look over the new tires themselves for proper seating, correct inflation, and any signs of interference once the car is back on the ground.
A vintage Austin that has spent long periods parked deserves an especially careful once-over. Brake condition, wheel-bearing play, alignment concerns, and old suspension bushings can all affect how the car feels on fresh tires, so a short local test drive is a smart step before a longer outing.
How should 7.50-13 tires on a collector 1966 Austin A 110 be maintained?
Collector-car tires should be checked regularly for inflation, tread wear, sidewall cracking, cuts, bulges, and signs of slow air loss. On a 1966 Austin A 110, low annual mileage does not eliminate the need for inspection, because age and storage conditions matter as much as miles.
Storage plays a big role in tire life on a seldom-driven car. Keeping the Austin away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and periodic inspections remain important even when the car is used mainly for shows, local drives, or seasonal events.
