1964 Toyota Tiara Tires

The 1964 Toyota Tiara uses two primary tire sizes: 560-13 and 590-13. Both are vintage numeric bias-ply sizes built for 13-inch rims, and the Tiara 1900 is associated with both fitments rather than just one.

That makes verification important before ordering replacement tires. Check the size already mounted on the car, confirm the actual wheel diameter, and make sure the wheel width suits the tire being considered. A Tiara that has been modified, fitted with replacement wheels, or changed over in the past may no longer match the setup you expect from the model name alone.

The 1964 Toyota Tiara tire fitments here are built around a 13-inch rim diameter. Both 560-13 and 590-13 use that same rim diameter, so the main wheel question is not diameter variation between sizes but whether the car still has the wheel setup that matches the tire you plan to use.

Rim width still matters even when the diameter is correct. The available bias-ply tires in these sizes show different rim-width ranges depending on the product, so it is wise to confirm both wheel diameter and wheel width before choosing among 560-13 and 590-13 options. That becomes especially important if the car has replacement wheels from an earlier restoration.

On a 1964 Toyota Tiara, 560-13 is a numeric bias-ply tire size. The 560 refers to an approximate 5.60-inch nominal section width, while the 13 refers to the wheel diameter in inches. It is a vintage sizing system commonly seen on compact cars from this era.

The practical takeaway is that this older size format does not read like a modern metric radial size. A buyer comparing options should look beyond the code itself and confirm construction type, wheel width, and intended appearance. That helps avoid assuming a modern-looking metric number or a different bias-ply size will behave the same on the Tiara’s existing wheel setup.

For the 1964 Toyota Tiara, 560-13 is a primary bias-ply tire size. It uses a traditional vintage numeric sizing format rather than a modern radial designation, and the available 560-13 products in this fitment are bias-ply tires.

That matters because a buyer may be choosing between preserving the car’s traditional construction or considering a separate radial-equivalent size. Bias-ply selection keeps the original-style format and appearance conversation intact, especially when whitewall style is part of the decision. Any move away from 560-13 bias-ply should be treated as a conversion that deserves a wheel, dimension, and clearance check.

Radial equivalents for 560-13 are 155R13, P155/75R13, and P155/70R13. Radial equivalents for 590-13 are 165R13, P165/75R13, and P175/70R13. In each group, the first is an 80-series metric radial, the second is a 75-series P-metric radial, and the third is a 70-series P-metric radial.

These equivalents give a Tiara owner more than one sizing convention to consider, but they should not be treated as automatic substitutes. The recommended rim-width range is 4-5 inches, and the final choice still needs to be checked against the car’s actual wheel width, overall tire-to-body clearance, and the size currently used on the vehicle. That is especially important when choosing between 560-13 and 590-13 starting points.

Start by identifying whether the car is using 560-13 or 590-13, then compare only the radial-equivalent sizes tied to that primary fitment. For this Tiara, that means staying within the 155R13, P155/75R13, and P155/70R13 group for 560-13, or the 165R13, P165/75R13, and P175/70R13 group for 590-13.

Next, confirm that the wheel falls within the 4-5 inch rim-width range and inspect for adequate clearance at the fenders and steering components. A radial conversion can also expose issues with tired suspension parts, alignment, or prior wheel changes that were less noticeable with old tires. The safer approach is to verify the whole setup before treating a radial equivalent as road-ready.

The first consideration is using the correct primary size for the car’s present setup, since the 1964 Toyota Tiara is associated with both 560-13 and 590-13. After that, the key choices are construction, whitewall style, brand, tire series, and whether the wheel width matches the tire’s requirements.

A restoration-minded owner may focus on traditional bias-ply construction and a whitewall treatment that suits the car’s character, while another owner may be more concerned with evaluating a radial equivalent. Product details such as max load capacity at stated pressure and rim-width range are also useful comparison points. Matching the tire to the actual wheel and intended use matters more than choosing by appearance alone.

The available sidewall styles for 1964 Toyota Tiara tires include narrow whitewall and wide whitewall options. In 560-13, both narrow and wide whitewall choices are available, while 590-13 is represented by a wide whitewall offering.

That makes sidewall style an appearance decision as much as a fitment decision. A narrow whitewall gives a more restrained presentation, while a wide whitewall creates a more pronounced period-style look on a small 1960s sedan. Since sidewall style does not change the need for correct size and wheel compatibility, it should be selected only after the proper 13-inch tire size has been confirmed.

BFGoodrich and Firestone offer tires in the sizes used by the 1964 Toyota Tiara. BFGoodrich appears in both 560-13 and 590-13, while Firestone is available in 560-13, giving buyers a mix of classic brand presentation within the Tiara’s vintage bias-ply fitment range.

Brand choice should be weighed alongside tire series, whitewall style, and wheel-width compatibility rather than treated as a stand-alone decision. In this application, BFGoodrich includes Silvertown Classic Bias Ply options, while Firestone offers a Firestone Classic Bias Ply alternative. The more useful comparison is how each product aligns with the car’s current size, desired appearance, and wheel setup.

A period-style 1964 Toyota Tiara generally starts with one of its primary bias-ply sizes, 560-13 or 590-13, rather than jumping straight to a modern radial format. That preserves the vintage numeric sizing language and the traditional construction style most buyers expect to see on an early 1960s compact sedan.

The next decision is appearance within the correct size, especially whitewall treatment and brand presentation. Because the Tiara is associated with two primary sizes, the car’s actual wheel-and-tire setup should be confirmed before focusing on looks. For owners pursuing strict originality, marque references and period photos can help narrow down which size and sidewall presentation best suit a specific restoration direction.

Both narrow whitewall and wide whitewall treatments can create a period-style look on a 1964 Toyota Tiara, depending on the visual result you want. Narrow whitewall appears in 560-13, while wide whitewall is available in both 560-13 and 590-13 fitments.

A narrow whitewall usually reads more restrained, while a wide whitewall has a stronger vintage presence on a compact sedan. The right choice should still follow the confirmed tire size on the car rather than the sidewall style you prefer. Appearance matters, but a restoration-oriented tire only works well when the base fitment, wheel dimensions, and overall stance of the Tiara are consistent.

Yes, modifications can affect tire fitment on a 1964 Toyota Tiara even when the car uses one of the correct 13-inch tire sizes. Aftermarket wheels, changes in wheel width, suspension work, or altered ride height can change how a 560-13, 590-13, or any radial equivalent sits in the wheel opening.

That is why a modified Tiara should be measured rather than assumed correct by model year alone. Check wheel diameter and width first, then look at steering travel, fender clearance, and any signs of rubbing. Cars restored over many decades sometimes carry mixed parts, so a quick physical inspection is often more valuable than relying on the car’s badge or trim name.

Before driving a 1964 Toyota Tiara on new tires, inspect the wheels for correct diameter and condition, confirm proper air pressure, and make sure the tires clear the body and steering components through their full range of motion. Lug hardware, valve stems, and general suspension condition also deserve attention.

A freshly mounted set of tires cannot compensate for cracked wheels, loose steering parts, or poor alignment. On an older compact car, it is also smart to recheck pressure after the first few drives and look for uneven wear or contact marks that suggest the setup needs adjustment. That kind of early inspection helps catch small fitment issues before they become road-use problems.

Collector-car tires on a 1964 Toyota Tiara should be maintained with regular pressure checks, visual inspection, and clean, dry storage conditions. Whether the car runs 560-13 or 590-13, watch for sidewall cracking, cuts, bulges, flat spotting from long storage, and signs of air loss before routine driving.

A lightly used car often ages its tires long before it wears them out, so tread depth alone is not enough. Keeping the Tiara away from prolonged sunlight, moisture, and ozone sources can help preserve tire condition between outings. It is also wise to inspect the spare and review the tires before any longer drive, especially after the car has been parked for an extended period.
