1966 Toyota Crown Tires

The 1966 Toyota Crown uses two tire sizes: 185R13 in radial construction and 700-13 in bias-ply construction. Both sizes are associated with the Crown and both are built around a 13-inch rim diameter, so the fitment question is more about construction and presentation than wheel diameter alone.

That means the next step is confirming which direction matches the car and its intended use. A 700-13 keeps a more traditional bias-ply look, while 185R13 follows a radial format. If the car has been modified with different wheels or suspension changes, verify the actual wheel width and available clearance before choosing between the two.

The 1966 Toyota Crown tire fitments here are built for a 13-inch rim. Both the 185R13 radial and the 700-13 bias-ply size share that same rim diameter, which simplifies the first stage of fitment compared with vehicles that changed wheel diameter across trims.

Rim diameter is only one part of the check, especially when comparing bias-ply and radial choices. Wheel width still matters, and the radial equivalents tied to 700-13 call for a 4- to 6-inch rim width range. It is also smart to confirm the actual wheels on the car, since older restorations sometimes wear non-original replacements.

On a 1966 Toyota Crown, 700-13 is a numeric bias-ply tire size. The 700 designation represents a nominal section width with the decimal omitted, and the 13 indicates the wheel diameter in inches. It is the vintage-style sizing format many owners associate with period passenger-car tires.

Understanding that format helps when comparing it with a radial like 185R13, because the numbers are expressed in different systems. A buyer considering a change from 700-13 to a radial alternative should compare the wheel setup, the intended appearance of the car, and the available tire choices rather than assuming every 13-inch tire behaves the same way.

For the 1966 Toyota Crown, 700-13 is a bias-ply tire size. It represents the traditional construction option for this car, while 185R13 is the radial-format fitment associated with the same 13-inch wheel diameter.

That distinction matters because construction affects both presentation and selection. A 700-13 bias-ply keeps a stronger vintage character, especially with a Wide Whitewall offering, while the radial path uses a different sizing format. Before changing from one construction type to the other, confirm the wheel width and make sure the car’s current setup has the clearance needed for the tire you are considering.

Radial equivalents for 700-13 include 185R13 as an 80-series metric radial, P185/75R13 as a P-metric 75-series radial, and P205/70R13 as a P-metric 70-series radial. These are equivalent-size alternatives tied to the original 700-13 fitment rather than additional primary factory-style sizes.

Each option keeps the 13-inch rim relationship but uses a different sizing convention, so selection should not stop at the size code alone. The recommended rim width range attached to these equivalents is 4 to 6 inches. Wheel width, tire clearance, and the car’s intended look should all be checked before settling on a radial conversion.

That depends on what matters most for the car. A 700-13 bias-ply tire suits an owner who wants a more traditional period-style appearance, while 185R13 follows a radial format that many buyers consider when they want a more modern tire construction on the same 13-inch rim diameter.

The best choice starts with the condition and configuration of the car rather than a blanket rule. A restoration-focused Crown may favor the visual character of a bias-ply whitewall, while a driver-oriented car may point toward the radial path. Wheel width, overall fit on the car, and any previous changes to suspension or wheels should be reviewed before changing constructions.

Start with the role of the tire on the car. On a 1966 Toyota Crown, 700-13 is the bias-ply choice, so the decision centers on maintaining a traditional construction and appearance rather than moving into radial sizing. Sidewall style is especially important here because the available Firestone option uses a Wide Whitewall.

Selection should also include practical details such as wheel width and the car’s intended use. The available 700-13 product carries a 4.00 to 5.00 inch rim width specification, so that should match the wheel on the car. It also helps to think about whether the Crown is being restored for shows, weekend driving, or a broader touring role.

The available sidewall styles for 1966 Toyota Crown tires here are Blackwall and Wide Whitewall. The 185R13 Michelin radial uses a Blackwall presentation, while the 700-13 Firestone bias-ply tire is offered with a 5/8 inch Wide Whitewall.

That difference has a big effect on the car’s overall look, especially on a mid-1960s sedan where the tire is part of the visual profile. A Blackwall tends to look more restrained and functional, while a Wide Whitewall leans harder into vintage character. The right choice depends on whether the Crown is being kept understated, restored in period style, or balanced between the two.

Michelin and Firestone both offer relevant tire choices for the 1966 Toyota Crown. Michelin covers the 185R13 radial fitment with the XAS-FF series, while Firestone covers the 700-13 bias-ply fitment with the Classic Bias Ply series.

Those brands matter mainly because they line up with different construction and appearance goals rather than because one should automatically be preferred. A buyer comparing them should look at the correct size first, then compare sidewall treatment, tire series, rim-width compatibility where stated, and how each tire suits the intended role of the car on the road.

For a period-style 1966 Toyota Crown, the 700-13 bias-ply fitment is the natural starting point because it retains the vintage sizing system and construction associated with the car’s era. In the available choices, that also opens the door to a Wide Whitewall presentation that can strongly influence the car’s restored appearance.

A restoration-focused choice still deserves a little homework, especially if exact originality matters. Tire brand, sidewall treatment, and visual details should be compared against marque-specific photos, period literature, or club guidance if the car is being finished to a very precise standard. For many owners, though, the correct size and era-appropriate construction are the key first decisions.

On a restored 1966 Toyota Crown, tire construction affects the visual impression almost immediately. A 700-13 bias-ply tire gives the car a more traditional mid-1960s presentation, while a 185R13 radial introduces a later-style metric sizing format and, in the available product choice, a Blackwall appearance.

The visual result is not just about the sidewall color. Construction, size format, and sidewall styling work together to shape how authentic or updated the car feels at a glance. Owners building a show-oriented Crown often weigh that carefully, while those planning regular road use may accept a less traditional look in exchange for a radial-format tire.

Yes. Even though the 1966 Toyota Crown uses 13-inch tire fitments, changes such as aftermarket wheels, altered wheel width, suspension work, or body modifications can change which tire setup works comfortably on the car. That matters whether the choice is the original-style 700-13 bias-ply path or a radial-format alternative.

The safest approach is to inspect the car as it sits today instead of assuming it still matches a stock wheel package. Check wheel diameter and width, then look at steering clearance, fender clearance, and the space around suspension components. Those checks become especially important when converting from bias-ply sizing to one of the radial-equivalent formats.

Before driving a 1966 Toyota Crown on new tires, inspect the wheels for the correct diameter and sound condition, then look over the suspension, steering components, and alignment-related wear points. It also helps to confirm that the chosen tire size matches the car’s intended setup, especially when deciding between 700-13 bias-ply and 185R13 radial construction.

A quick road-use check should also include tire pressure, valve condition, lug-nut torque, and visual clearance at full steering lock. On collector cars that spend long periods parked, pay close attention to old cracking, bulges, or other signs of age on any tire being replaced or kept as a reference. A careful inspection makes the first drive much less uncertain.

700-13 tires on a collector 1966 Toyota Crown should be maintained with regular pressure checks, visual inspections, and careful storage habits. Because collector cars are often driven infrequently, the tire’s condition can change with age even when tread wear stays minimal. Sidewall cracking, cuts, bulges, and slow air loss deserve attention before every meaningful outing.

Storage environment matters almost as much as mileage. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber over time. It is also worth checking that the tires are wearing evenly and that the car rolls and steers smoothly, since long periods of inactivity can mask alignment or suspension issues.
