1955 Ford Prefect Tires

A 1955 Ford Prefect uses either a 145R13 radial or a 520-13 bias-ply tire. Both sizes are associated with the Prefect 100E and both use a 13-inch rim, so the main difference is construction type and sizing format rather than wheel diameter.

That means the first step is deciding which fitment path matches the car and its intended use. A 520-13 keeps the car in a traditional numeric bias-ply format, while 145R13 moves into a Euro-metric radial format. Checking the actual wheels on the car still matters, especially if it has been altered over the years.

The 1955 Ford Prefect uses a 13-inch rim with both of its supported tire sizes. The 145R13 radial and the 520-13 bias-ply are both built around the same 13-inch wheel diameter, which keeps rim diameter straightforward even though construction choices differ.

Rim diameter is only part of the fitment picture, so it helps to confirm wheel width before making a final tire choice. Some 145R13 and 520-13 products include specific rim-width guidance, and that becomes especially important if the car has replacement wheels or if a radial alternative is being considered.

The 1955 Ford Prefect 100E is associated with the same two fitment paths used on this page: 145R13 in radial construction and 520-13 in bias-ply construction. There is no separate tire-size split within the covered 100E listing that changes the basic fitment picture.

That makes the buying decision more about construction, appearance, and wheel compatibility than about sub-model differences. Owners restoring a more traditional look often start with 520-13, while drivers considering a radial setup look at 145R13 or the radial equivalents tied to 520-13 after confirming wheel width and vehicle clearance.

520-13 is a bias-ply tire size for the 1955 Ford Prefect. It uses the older numeric bias-ply sizing system, where the 5.20 designation refers to nominal section width and the 13 identifies the wheel diameter in inches.

That matters because a 520-13 keeps the car in its traditional construction style and opens up appearance choices such as blackwall, narrow whitewall, and wide whitewall. Anyone moving away from that fitment toward a radial should compare wheel width, overall tire dimensions, and clearance rather than assuming every radial alternative behaves the same.

Radial equivalents for 520-13 include 155R13, P155/75R13, and P155/70R13. Those represent three different radial formats: an 80-series metric radial, a 75-series P-metric radial, and a 70-series P-metric radial.

These sizes give the owner more than one way to compare a radial alternative to the original bias-ply fitment, but they should not be treated as automatic substitutes. A recommended rim-width range of 4 to 5 inches is associated with the equivalents, and final selection should also account for the car's actual wheel width, clearance, and overall setup.

Start by confirming the wheel diameter and width actually on the car, then compare the intended radial size against the original 520-13 fitment. For a 1955 Ford Prefect, the main radial alternatives tied to 520-13 are 155R13, P155/75R13, and P155/70R13, and 145R13 is also a primary radial fitment on a 13-inch rim.

After that, inspect steering and fender clearance, suspension condition, and how the car sits at normal ride height. Cars that have been stored a long time or modified with different wheels can change the result. A radial conversion should be treated as a full fitment check, not just a simple size swap.

Choosing a 520-13 tire starts with confirming that the car is staying with the traditional bias-ply size rather than moving to 145R13 or a radial equivalent. Once that is settled, the main variables are sidewall style, tire series, rim-width compatibility, and whether the car is being restored for appearance or prepared for regular road use.

Within 520-13, the available options include Firestone Classic Bias Ply and Premium Sport Lowrider products, with blackwall, narrow whitewall, and wide whitewall presentations. Some products also include rim-width and load information, which can help narrow the choice. The best match is the one that suits both the wheel and the look you want.

1955 Ford Prefect tires are available in several sidewall styles depending on size and product line. Blackwall appears in both 145R13 radial and 520-13 bias-ply offerings, while 520-13 also includes narrow whitewall and wide whitewall choices for a more vintage visual treatment.

That makes sidewall selection an important part of the decision, especially on a small postwar sedan where tire appearance is highly visible. A blackwall tends to keep the look simple and understated, while narrow and wide whitewalls push the car toward a more restoration-oriented presentation. Appearance should still be considered after the correct size and construction are confirmed.

Tires for the 1955 Ford Prefect are available from Michelin, Firestone, and Premium Sport. Michelin and Firestone appear in the 145R13 radial size, while Firestone and Premium Sport cover the 520-13 bias-ply size with different series and sidewall treatments.

Brand choice is only one part of the comparison, since the more meaningful differences may be construction, sidewall style, and tire series. A buyer deciding between 145R13 and 520-13 should settle the fitment path first, then compare the available brand options within that size instead of trying to compare unlike constructions directly.

A period-style 1955 Ford Prefect usually starts with the 520-13 bias-ply size, because that keeps the car in its traditional numeric sizing format and preserves the vintage construction style. Within that size, there are blackwall, narrow whitewall, and wide whitewall options that can shape the car's finished appearance in noticeably different ways.

The right choice depends on how strictly the car is being restored and what visual character you want it to carry. When exact originality matters, marque references and period photos are worth reviewing before settling on a sidewall treatment. For many owners, 520-13 is the natural foundation for a restoration-oriented look.

Tire construction changes more than the driving feel on a restored 1955 Ford Prefect; it also changes the way the car presents visually. A 520-13 bias-ply gives the car a more traditional small-car stance and opens the door to classic sidewall treatments, while a 145R13 radial introduces a more modern-looking size format.

That difference becomes especially important on a compact sedan where the tires occupy a visible part of the car's overall profile. Owners building a restoration-oriented car often place more weight on the bias-ply look, while owners planning regular road use may accept a radial appearance. The right answer depends on the balance between presentation and practicality.

Yes, modifications can affect tire fitment on a 1955 Ford Prefect even when the nominal size appears correct. Different wheel widths, non-original wheel offsets, suspension changes, lowering, or body alterations can all change how a 145R13, 520-13, or a radial equivalent sits in the wheel opening.

That is why the car should be checked as it actually stands today rather than by model name alone. Turning clearance, fender clearance, and ride-height clearance all matter, especially on a small car with limited space around the tires. Any change in wheel or suspension setup makes a fresh fitment review worthwhile.

Before driving a 1955 Ford Prefect on new tires, inspect wheel condition, valve stems, lug hardware, and the general condition of the suspension and steering components. Tire pressure should be set correctly, and the tires themselves should be checked for proper seating, visible damage, and any signs of interference once the car is on the ground.

A short, careful road test helps confirm that the car tracks properly and that nothing rubs during turns or suspension movement. It also makes sense to recheck pressure and fastener security after the first miles. On a collector-era car, small issues in old wheels or chassis parts can show up quickly once fresh tires are installed.

520-13 tires on a collector 1955 Ford Prefect should be maintained with regular pressure checks, visual inspections, and careful storage habits. Because collector cars often spend long periods parked, the sidewalls and tread deserve close attention for cracking, cuts, bulges, irregular wear, or slow air loss before the car is driven.

Storage conditions matter almost as much as mileage, so it helps to keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources. Moving the vehicle periodically can also reduce long-term flat spotting. Any tire that shows age-related deterioration should be evaluated before road use, even if the tread still looks deep.
