1953 AC Typen Tires

The 1953 AC Typen uses two primary tire sizes: 185R16 in radial construction and 670-16 in bias-ply construction. Both are 16-inch fitments, so the real distinction is not wheel diameter but the type of tire construction and the style of setup the car is using.

That matters because a 1953 AC Typen kept in a period-style configuration may call for a different tire choice than one being set up for more modern radial road use. Before selecting a tire, confirm the actual wheels on the car, the wheel width, and whether any earlier owner changed the tire construction or wheel setup.

The 1953 AC Typen uses a 16-inch rim diameter with both of its primary tire sizes, 185R16 and 670-16. Even though the constructions differ, the wheel diameter remains the same, which helps narrow the fitment decision to tire type, wheel width, and the overall setup of the car.

Rim diameter alone does not settle the choice, because radial and bias-ply tires can have different wheel-width needs within the same 16-inch diameter. It is smart to measure the wheels actually on the car and compare their width to the tire being considered, especially if the car has replacement wheels or an older restoration.

670-16 is a numeric bias-ply tire size. The 6.70 identifies the nominal section width in inches with the decimal omitted, and the 16 refers to the wheel diameter in inches. On a 1953 AC Typen, this size represents the traditional bias-ply fitment path rather than the radial 185R16 alternative.

Understanding that format helps when comparing vintage-style tires, because the number system does not read like a modern metric radial size. A buyer choosing 670-16 should focus on preserving the bias-ply construction type, confirming the wheel width suits the tire, and making sure the overall tire choice matches the car’s intended appearance and road use.

670-16 is a bias-ply tire size for the 1953 AC Typen. It uses the older numeric sizing format common to vintage cars, and it is distinct from the radial fitment choice of 185R16, even though both mount on 16-inch rims.

That difference affects more than the lettering on the sidewall. A bias-ply setup suits buyers aiming for a more traditional presentation and vintage driving feel, while a radial setup points in a different direction. Before changing from one construction to the other, check the wheel width, the condition of the suspension and steering components, and the clearance around the fenders and chassis.

Either construction can be appropriate for a 1953 AC Typen, depending on how the car is set up and what the owner wants from it. The bias-ply choice is 670-16, while the radial choice is 185R16, and both are built around a 16-inch rim diameter.

The better decision depends on whether the goal is a traditional period-style presentation or a radial-equipped driving setup. Construction changes should not be treated as automatic substitutions just because the rim diameter matches. Wheel width, tire clearance, and the condition of suspension and steering parts all deserve a careful look before committing to one approach.

A 1953 AC Typen being moved from 670-16 bias-ply tires to 185R16 radial tires should be checked at the wheel, suspension, and clearance level before the change is made. Both sizes use 16-inch rims, but construction changes still affect how the tire works with the car and the wheel.

Start by confirming wheel width and making sure the rims are suitable for the radial tire being considered. Then inspect steering travel, fender clearance, and the overall condition of bushings, springs, and alignment-related components. On an older British car, even small variations in wheel choice or chassis condition can change how comfortably a radial conversion works in practice.

Start with the basic fitment path: 670-16 if the car is being kept on a bias-ply setup, or 185R16 if it is using radial tires. From there, the main factors are wheel compatibility, construction type, tire series, and how closely the tire’s appearance matches the character you want for the car.

For many owners, the choice is as much about presentation as it is about fitment. A traditional bias-ply blackwall gives one look and feel, while a blackwall radial from Michelin, Avon, or Vredestein gives another. Comparing rim-width suitability, load figures where stated, and intended road use helps narrow the decision sensibly.

Tires for the 1953 AC Typen are available from Michelin, Avon, Vredestein, and Firestone. The radial 185R16 fitment includes Michelin X Radial, Avon Turbosteel CR6D, and Vredestein Sprint Classic, while the 670-16 bias-ply fitment includes Firestone Classic Bias Ply and Avon Turbospeed Mk4.

Brand choice should be considered alongside construction and series, not in isolation. Some owners will be comparing vintage-style bias-ply options, while others will be looking at classic radial offerings. It makes sense to narrow the field by deciding first whether the car should stay with 670-16 bias-ply or move forward with the 185R16 radial route.

The 1953 AC Typen has several distinct tire series available depending on size and construction. In 185R16 radial form, choices include Michelin X Radial, Avon Turbosteel CR6D, and Vredestein Sprint Classic. In 670-16 bias-ply form, the available series include Firestone Classic Bias Ply and Avon Turbospeed Mk4.

Those series matter because they help separate a traditional bias-ply approach from a classic radial approach, even when the wheel diameter stays at 16 inches. A good comparison starts with the correct size and construction, then moves to series character, wheel-width suitability where stated, and whether the finished look should lean more vintage or more touring-oriented.

For a period-style 1953 AC Typen, the 670-16 bias-ply size is the natural starting point because it preserves the vintage numeric sizing format and traditional construction type. Available blackwall options in that size support a more historically appropriate visual character than a modern-looking radial presentation.

That does not automatically make every 670-16 the exact same restoration choice, since brand and tire series still affect the final look. If exact originality matters, compare your car against marque references, period photos, and restoration documentation. For many owners, staying with the correct bias-ply size and overall vintage profile is the most important first step.

Tire construction changes the visual impression of a restored 1953 AC Typen even when the rim diameter remains 16 inches. A 670-16 bias-ply carries the older numeric size format and a more traditional vintage presentation, while a 185R16 radial introduces a later-style metric sidewall treatment and overall look.

That difference is often noticeable on a car with narrow body lines and classic postwar proportions. Owners restoring for period character usually begin by deciding whether the car should read as bias-ply traditional or radial updated. Once that choice is settled, blackwall series and wheel compatibility become the next practical details to compare.

Yes, modifications can affect tire fitment on a 1953 AC Typen even when the car still uses a 16-inch wheel. Changes to wheel width, wheel offset, suspension height, spring condition, or body clearance can influence how either a 670-16 bias-ply or 185R16 radial sits and moves within the car’s wheel openings.

That is especially important on older cars that may have gone through multiple restorations or owner changes over the years. If the Typen has replacement wheels, altered suspension, or brake modifications, measure the wheels and inspect clearance at full steering travel and normal ride height before settling on a tire size or construction.

Before driving a 1953 AC Typen on new tires, inspect the wheels for correct diameter and sound condition, then check that the tires are properly seated and inflated for the application. The suspension, steering joints, bushings, and brakes also deserve attention, because an older car can place unusual demands on a fresh set of tires.

A short local drive is the best first test after installation. Watch for rubbing, steering pull, vibration, unusual noise, or signs of contact at the fenders and suspension. It is also wise to recheck pressure and visual condition after the first few outings, especially on a collector car that may not be driven regularly.

Tires on a collector 1953 AC Typen should be checked regularly for air loss, sidewall cracking, tread wear, flat spotting, bulges, and cuts, even if the car is driven only occasionally. Bias-ply and radial tires both age with time, and long storage periods can hide problems until the car is back on the road.

Storage conditions matter almost as much as mileage on a lightly used vintage car. Keep the tires away from prolonged sunlight, moisture, excess heat, and ozone sources such as electric motors when possible. Before any longer drive, confirm pressure, inspect the tread and sidewalls closely, and make sure the spare and jack equipment are also serviceable.
