1951 AC Typen Tires

The 1951 AC Typen uses two primary 16-inch tire sizes: 670-16 in bias-ply construction and 185R16 in radial construction. Both sizes are associated with the model, including the 2-Liter sub-model, so the fitment question is less about year and model identity and more about which tire construction and wheel setup the car is using.

That makes wheel confirmation especially important before ordering tires. A car that has remained closer to a traditional setup may suit 670-16 bias-ply tires, while a car already running a radial-oriented arrangement may use 185R16. Checking the wheel diameter, wheel width, and available clearance helps narrow the choice without assuming both options belong on every individual car exactly the same way.

The 1951 AC Typen uses a 16-inch rim diameter with both of its primary tire sizes. That shared rim diameter is one reason the tire decision centers more on construction type and wheel suitability than on moving between completely different wheel diameters.

Rim diameter alone is not the whole story, though. Some 185R16 radial products are intended for wider rim ranges than 670-16 bias-ply products, so the actual wheel width should be checked before choosing between them. That is especially useful on collector cars that may have changed wheels over the years or may now be carrying a different setup than expected.

The 1951 AC Typen 2-Liter uses the same two primary tire sizes associated with the model overall: 185R16 in radial form and 670-16 in bias-ply form. In practical terms, the sub-model does not introduce a separate wheel diameter or a completely different fitment family.

That still leaves an important choice for the owner. A 2-Liter set up around a traditional look may remain with 670-16 bias-ply tires, while another car may already be configured for 185R16 radials. Looking at the tires currently on the car, the wheel width, and the intended appearance will usually answer the question more clearly than the sub-model name alone.

Start with the correct size and construction for the car's current setup. The 1951 AC Typen can use either 670-16 bias-ply tires or 185R16 radial tires, both on 16-inch rims, so the key factors are wheel compatibility, construction type, and whether the goal is a more traditional or more radial-oriented driving presentation.

Brand and series choice then become the finer points. Firestone and Avon cover the 670-16 bias-ply side, while Michelin, Avon, and Vredestein offer 185R16 radial choices. Comparing sidewall style, rim-width suitability, load figures where stated, and the car's intended use will help narrow the field without turning a period-style car into something visually out of character.

Tire choices for the 1951 AC Typen come from Michelin, Avon, Vredestein, and Firestone. Michelin, Avon, and Vredestein appear in the 185R16 radial size, while Firestone and Avon are available in the 670-16 bias-ply size.

That mix gives owners a useful spread of vintage-oriented options without forcing one construction type. The practical way to use the brand list is to filter it through the car's actual tire size, wheel dimensions, and intended appearance. Once the correct size and construction are settled, comparing the available tire series within those brands becomes much more meaningful than choosing by brand name alone.

The 1951 AC Typen is served by several distinct tire series. In 185R16 radial form, options include Michelin X Radial, Avon Turbosteel CR6D, and Vredestein Sprint Classic. In 670-16 bias-ply form, available series include Firestone Classic Bias Ply and Avon Turbospeed Mk4.

Series names help separate the choices by construction and presentation more than by outright fitment. A buyer deciding between radial and bias-ply should first settle that larger question, then compare the series available in the chosen size. That approach keeps the selection process focused on wheel compatibility and intended character instead of treating all available series as interchangeable options.

For a period-style 1951 AC Typen, the 670-16 bias-ply fitment is the most traditional starting point. It keeps the car in a vintage numeric bias-ply size and is available in Blackwall form from Firestone and Avon, which suits the restrained presentation many owners want on an early postwar British car.

That does not make every 670-16 automatically the right restoration choice for every car. Owners pursuing higher-level originality should compare the tire selection against marque references, period photos, and restoration goals, while also confirming wheel width and general fit. The point is to match the car's visual character and setup, not just to choose the oldest-looking tire available.

Tire construction changes the visual impression of a restored 1951 AC Typen as much as it changes the driving feel. A 670-16 bias-ply gives the car a more traditional vintage presentation, while a 185R16 radial usually reads as a later-style touring choice even though it still uses the proper 16-inch rim diameter.

Because all of the available products here are Blackwall tires, the appearance difference comes mainly from the tire size format and construction rather than from whitewalls or stripes. That makes the choice fairly clean: stay bias-ply for a more period-oriented look, or move to a radial if road-use priorities outweigh keeping the car as visually traditional as possible.

Yes, modifications can affect tire fitment on a 1951 AC Typen even when the tire size itself is one of the recognized 16-inch options. Wheel changes, altered wheel width, suspension work, ride-height changes, or body clearance differences can all influence whether a 670-16 bias-ply or 185R16 radial is the better match for the car as it sits today.

That matters because a collector car may no longer be wearing its original-style wheels or suspension geometry. Looking at the actual rim width, steering clearance, and fender space before selecting tires is more useful than relying on the year and model alone. Any car with aftermarket wheels deserves that extra check before moving between bias-ply and radial constructions.

Before driving a 1951 AC Typen on new tires, inspect the wheels for the correct 16-inch diameter, confirm the wheel width suits the chosen tire, and make sure the tires are mounted and inflated properly. It is also wise to check valve stems, balance, and basic clearance at the fenders and steering components.

A broader road-use inspection is just as important on an older car. Look over the suspension, steering, wheel bearings, and brake system, then recheck tire pressure after the first drives. Even the correct 670-16 or 185R16 tire cannot compensate for worn chassis parts, and an otherwise proper tire choice should still be treated as one part of getting the car safely back on the road.

Collector-car tire maintenance starts with regular pressure checks and frequent visual inspections. Whether the 1951 AC Typen is running 670-16 bias-ply tires or 185R16 radials, owners should watch for cracking, bulges, cuts, uneven wear, and signs of air loss, especially on cars that spend long periods parked between drives.

Storage conditions matter almost as much as mileage. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires over time, and occasional movement can reduce flat-spotting on low-use vehicles. Any tire that shows age-related deterioration should be evaluated before road use, even if the tread still looks serviceable.
