1963 Toyota Tire Fitment Guide

1963 Toyota vehicles use four sizes split by model. The Toyota Crown uses either 185R13 in radial construction or 700-13 in bias-ply construction, while the Toyota Tiara uses either 165R13 in radial construction or 590-13 in bias-ply construction. All four sizes fit 13-inch rims, but the rim-width ranges are not the same where that information is available: 700-13 fits 4.00 to 5.00-inch rims, 165R13 fits 4.50 to 6.00-inch rims, and 590-13 fits 3.50 to 4.00-inch rims.

That means year and make alone are not enough to pick a tire for a 1963 Toyota. Start by confirming whether the car is a Crown or a Tiara, then decide whether you want a bias-ply tire for period appearance or a radial for a more modern driving feel. Once you have narrowed it that far, confirm the wheel width on the actual car before making a final size choice.

On a 1963 Toyota, 700-13 is a numeric bias-ply size. The 700 portion is the older nominal section-width code, and the 13 identifies the wheel diameter in inches. For the Toyota Crown, this size is the bias-ply option and is available with a wide whitewall sidewall, fitting 4.00 to 5.00-inch rims in the available fitment range.

Numeric sizes like 700-13 are common on American and import cars from the bias-ply era, so they look familiar and correct on an early-1960s restoration. They do not translate one-for-one to a modern metric size simply by reading the code. If your 1963 Toyota Crown still has its original-style wheels and you want an authentic appearance, 700-13 is the size to compare first.

On a 1963 Toyota, 185R13 and 165R13 are metric radial sizes. The first number is the nominal section width in millimeters, the R denotes radial construction, and the 13 is the rim diameter in inches. The 185R13 fits the Toyota Crown, while the 165R13 fits the Toyota Tiara; both are available as blackwall radials, and the available examples carry H speed ratings with a 130 mph ceiling.

Those sizes appeal to owners who want a radial in the car’s original wheel diameter rather than a bias-ply look. Even though both are 13-inch radial sizes, they are not interchangeable between the Crown and Tiara just because they share the same rim diameter. Width and overall fitment still need to match the specific model and wheel.

For a 1963 Toyota, the choice depends on the model and the character you want from the car. A Toyota Crown can use either 185R13 radial or 700-13 bias-ply, while a Toyota Tiara can use either 165R13 radial or 590-13 bias-ply. The radial options are blackwalls, while the bias-ply options here are wide whitewalls, so the decision affects both driving character and appearance.

Owners restoring a 1963 Toyota for period presentation usually gravitate toward the bias-ply option because it preserves the look and construction style expected for the era. Owners who plan to drive the car more often often prefer the radial route because it keeps the 13-inch fitment while moving to radial construction. Either way, stay with the size that matches your specific Crown or Tiara.

1963 Toyota tires are available in two distinct sidewall styles across these sizes. The radial sizes, 185R13 for the Crown and 165R13 for the Tiara, come as blackwalls. The bias-ply sizes, 700-13 for the Crown and 590-13 for the Tiara, come as wide whitewalls, giving each model a visibly more period-oriented presentation.

That choice matters if you are balancing authenticity, personal taste, and how the car will be displayed. A blackwall radial gives a cleaner, more understated look that suits an owner who values radial construction and regular road use. A wide whitewall bias-ply tire brings the stronger early-1960s visual signature many restorers want on a compact sedan from this period.

Several established brands cover 1963 Toyota sizes. Michelin offers the 185R13 Crown radial and two versions of the 165R13 Tiara radial, Dunlop also offers the 165R13 Tiara radial, Firestone covers the 700-13 Crown bias-ply size, and BFGoodrich covers the 590-13 Tiara bias-ply size. That gives Crown owners one brand path in each construction and Tiara owners a broader radial selection plus one bias-ply choice.

Brand choice matters most after the model and size are settled, not before. A Crown owner choosing between Michelin radial and Firestone bias-ply is really deciding between two different fitment philosophies, while a Tiara owner comparing Michelin and Dunlop within 165R13 is comparing products within the same radial size. Narrow the car and the size first, then compare brand details within that fitment.

Available rim-width guidance for 1963 Toyota tires varies by size. The 700-13 Crown bias-ply size fits 4.00 to 5.00-inch rims, the 165R13 Tiara radial fits 4.50 to 6.00-inch rims, and the 590-13 Tiara bias-ply fits 3.50 to 4.00-inch rims. Every size here uses a 13-inch rim diameter, but width still matters because it affects how the tire sits and performs on the wheel.

A 13-inch wheel is only part of the fitment picture on a 1963 Toyota. Before mounting tires, measure the actual wheel width rather than assuming all stock-looking steel wheels are the same. That is especially important if the car has had wheel changes over the years or if a previous owner mixed parts from another early Toyota or another small import.

Inner-tube requirements for 1963 Toyota tires depend on the exact size and product. The 185R13 Crown radial and the 165R13 radial products are tubeless, while tube fitment is not stated in the same way for the 700-13 and 590-13 bias-ply products. On an early-1960s car, wheel design and condition can matter just as much as the tire’s construction when deciding whether a tube is appropriate.

The practical move is to inspect the actual wheel before mounting tires on a 1963 Toyota, especially if the car still wears original rims. A tubeless radial may still be paired with a wheel that needs special attention because of age, corrosion, or bead-seat condition. If you are preserving original wheels, it is wise to confirm the setup with a tire professional familiar with older import steel wheels.

Original 1963 Toyota wheels can only be shared within the limits of model-specific size and wheel width, even though all four tire sizes use a 13-inch rim diameter. The Crown’s 185R13 and 700-13 share the same wheel diameter, and the Tiara’s 165R13 and 590-13 do as well, but the available rim-width ranges show that these sizes are not all aimed at the same wheel widths.

That means a 13-inch wheel from one 1963 Toyota model should not be treated as automatically correct for the other model or for both of its available tire types. If you are moving from bias-ply to radial on the same car, confirm wheel width and condition first. Keeping the right wheel under the right size is the cleanest way to avoid clearance and mounting issues.

A 1963 Toyota should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Keep the tires clean, maintain inflation, and move the car periodically if possible. Because 1963 Toyota fitments can be either bias-ply or radial depending on the model and size choice, remember that bias-ply tires tend to flat-spot more readily during long static storage.

That matters most for collector cars that spend more time parked than driven. If the car will sit for months, rolling it occasionally or supporting it in a way that reduces constant load can help preserve the tires’ shape. Good storage habits protect both blackwall radials and wide whitewall bias-ply tires, but the whitewall products also benefit from careful cleaning to avoid staining and discoloration.

Tires on a 1963 Toyota usually age out before they wear out, since collector cars often accumulate limited mileage. A sound rule is to begin close evaluation once tires reach about five to seven years of age and to treat roughly ten years as the point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the tire remains the starting point for determining actual age.

A low-mile Crown or Tiara can still be riding on old rubber that looks presentable at first glance, especially if the car only appears at occasional events. Age-related hardening, cracking, and internal deterioration matter more than odometer reading on a collector tire. If a 1963 Toyota has unknown-age tires, verify the date code before assuming the tires are still suitable for regular road use.

Tires on a 1963 Toyota should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread damage, irregular wear, bulges, pressure loss, and anything unusual around the bead or valve area. On a car that may sit for extended periods, those small checks matter more than they would on a modern daily driver.

Frequent inspection is especially worthwhile on an older Crown or Tiara because the car’s age means the tire is only one part of a larger mechanical picture. If the car runs bias-ply tires, check for flat-spotting after storage; if it uses older wheels, pay close attention to valve stems and sealing surfaces. A five-minute pre-drive look can prevent a roadside problem on a much longer outing.

A 1963 Toyota Crown would originally have been associated with bias-ply construction in period, which aligns with the 700-13 bias-ply fitment offered here. The 185R13 size is the radial alternative for the same model and suits owners who want to keep the 13-inch wheel diameter while moving away from a period-correct construction style. No original-equipment brand should be assumed without checking factory literature or marque-specific references.

For a restoration, that makes the first question less about brand and more about whether the car is being judged for authenticity or prepared for regular driving. If originality is the priority, start with the 700-13 fitment and confirm sidewall expectations through Toyota club resources or period brochures. If the goal is road use with a more modern tire design, the 185R13 radial becomes the more practical branch to explore.

Correct tire fitment matters on a shown 1963 Toyota because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style quickly. A Crown wearing a radial blackwall presents differently from a bias-ply wide whitewall, and the same is true of the Tiara’s 165R13 radial versus 590-13 bias-ply fitment. On an originality-focused car, those differences can change the overall visual and historical impression.

That does not mean every event judges the same way, but it does mean tire choice should match the level of authenticity you want the car to project. A local driver-quality show may be more forgiving than a marque-specific judged event. Before finalizing a 1963 Toyota restoration, compare your chosen size and sidewall style with period photos and event guidance from Toyota collector groups.

A 1963 Toyota Tiara would have belonged to the bias-ply era, making the 590-13 bias-ply size the most natural historical reference point among the available fitments. The 165R13 size is the radial alternative and keeps the car on a 13-inch wheel while shifting to radial construction and a blackwall presentation. Original-equipment branding can vary by market and should be confirmed through period Toyota sources rather than assumed.

That distinction helps separate restoration choices from driver-oriented choices on a Tiara. If the car is being returned to an early-1960s appearance, the 590-13 wide whitewall better supports that goal. If the Tiara will be exercised more often and authenticity is not the only concern, the 165R13 radial gives you a modern construction in a size intended for that model.

1963 Toyota tires can be suitable for highway use when the size, condition, inflation, and overall vehicle condition are all right for the car. The available radial sizes, 185R13 and 165R13, carry H speed ratings with a 130 mph ceiling, while the 590-13 bias-ply carries an S rating with a 112 mph ceiling. Those figures are well above ordinary highway speeds, but tire age and condition remain more important than the rating itself on a collector car.

A 1963 Toyota Crown or Tiara also brings its own era-specific braking, suspension, and chassis limitations, so the car’s mechanical state matters as much as the tire. A fresh, properly matched tire does not override worn steering parts, old shocks, or poor alignment. If the car is prepared correctly, either construction can serve highway driving within the vehicle’s realistic operating envelope.

Inflation pressure on a 1963 Toyota should follow the vehicle manufacturer’s recommendation first, then be checked against the tire’s own load-and-pressure information where it is available. Among these sizes, 700-13 carries 1,270 pounds at 32 psi and 590-13 carries 970 pounds at 32 psi. Those figures describe rated load at a given pressure for those specific tires; they are not universal settings for every 1963 Toyota size.

Use that information carefully, because the Crown and Tiara do not share the same sizes and the radial products are different designs from the bias-ply options. Avoid borrowing a pressure number from one size and applying it to another just because both fit a 13-inch wheel. The owner’s manual, period factory guidance, and the tire maker’s specifications should agree before you settle on a running pressure.

Before a longer drive in a 1963 Toyota, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, and stable inflation pressure. Confirm that the tires match the car’s actual model, since Crown and Tiara use different sizes, and make sure the valve stems and wheel sealing surfaces are in good shape. A collector car’s spare is often overlooked, yet it may be the oldest tire on the vehicle.

That tire inspection should happen alongside a broader pre-drive mechanical check that suits an early-1960s car. Wheel bearings, brakes, coolant hoses, fuel hoses, and charging-system condition can matter just as much on a longer outing. Starting with the right tire size and a careful walk-around gives a 1963 Toyota a much better chance of completing the trip without drama.
