1965 Toyota Tiara Tires

The 1965 Toyota Tiara uses two primary bias-ply tire sizes: 560-13 and 590-13. Both sizes fit 13-inch rims, and the Tiara 1900 is associated with both, so this is not a case where one size automatically applies to every car without checking the existing wheel-and-tire setup.

The practical next step is to inspect the tires already on the car and confirm the wheel diameter before selecting a replacement. If originality in appearance matters, the choice may also come down to which size best matches the car’s current stance and whether a narrow or wide whitewall presentation is preferred.

The 1965 Toyota Tiara uses a 13-inch rim with both of its primary tire sizes, 560-13 and 590-13. Even though there are two tire sizes associated with the car, they share the same rim diameter, so the main fitment question is not wheel diameter alone but which size and wheel width combination is actually on the vehicle.

That matters because a correct 13-inch rim diameter does not eliminate the need to confirm wheel width and overall tire fitment. A Tiara that has been changed over the years may have different wheels than it left with, and that can influence which bias-ply size or radial-equivalent path makes the most sense.

On a 1965 Toyota Tiara, 560-13 is a vintage numeric bias-ply tire size. The 5.60 figure refers to the nominal section width in inches, and the 13 identifies the wheel diameter in inches. It is a traditional sizing format commonly seen on compact cars from this period.

Understanding that format helps when comparing it with modern radial equivalents, which use metric sizing instead of vintage numeric sizing. It also helps explain why a car can use a correct 13-inch wheel and still require careful size checking, especially if the goal is to preserve period-style proportions rather than simply match rim diameter.

For the 1965 Toyota Tiara, 560-13 is a bias-ply primary tire size. It uses the vintage numeric sizing format rather than a modern metric radial format, which makes it a natural choice for owners who want to keep the car in a traditional construction and period-style presentation.

That distinction matters because switching from bias-ply to radial changes more than just the lettering on the sidewall. Before making that move, it is smart to confirm wheel width, compare the intended radial-equivalent size carefully, and check fender and suspension clearance on the actual car rather than assuming the same rim diameter settles everything.

For 560-13, radial equivalents include 155R13, P155/75R13, and P155/70R13. For 590-13, radial equivalents include 165R13, P165/75R13, and P175/70R13. The first size in each group is an 80-series metric radial, followed by a 75-series P-metric option and then a 70-series P-metric option.

Those choices give the owner several ways to compare a modern radial format against the original bias-ply size, but they should still be treated as alternatives rather than automatic replacements. The 4-5 inch recommended rim-width range is useful, and it is worth verifying wheel width, overall package dimensions, and clearance before making a change.

Start by confirming which primary bias-ply size the car uses now, either 560-13 or 590-13, and then match that size to its appropriate radial-equivalent options. The wheel should be checked for the correct 13-inch diameter and for width suitability, since the radial-equivalent recommendations are tied to a 4-5 inch rim-width range.

Beyond the wheel itself, the smart checks are steering clearance, fender clearance, suspension condition, and the actual stance of the car. A Tiara that has been altered with different wheels or ride height may need closer review, and even an otherwise stock car benefits from checking fitment before changing both construction type and sizing convention.

The first decision is whether the car should use 560-13 or 590-13, since both sizes are associated with the 1965 Toyota Tiara and both are bias-ply fitments on 13-inch rims. After that, the choice becomes more specific: sidewall style, brand, tire series, and whether the goal is traditional bias-ply appearance or a carefully checked radial-equivalent alternative.

A restoration-oriented car may call for a period-style whitewall presentation, while a driver-focused car may lead the owner to compare radial-equivalent sizing. It also helps to verify wheel width and compare product details such as load rating and intended rim range so the selected tire suits both the vehicle setup and the way the car will be used.

Available sidewall styles for the 1965 Toyota Tiara include narrow whitewall and wide whitewall treatments, depending on the tire size and product selected. In 560-13, both styles are available, while 590-13 is represented by a wide whitewall option. Those choices can noticeably change the visual character of a small 1960s import.

Sidewall style should be chosen with the car’s intended appearance in mind rather than as an afterthought. A narrower whitewall can give a more restrained period feel, while a wider whitewall creates a stronger vintage statement. Matching the sidewall to the tire size already used on the car helps keep the overall look balanced.

BFGoodrich and Firestone both offer applicable tires for the 1965 Toyota Tiara. BFGoodrich appears in both 560-13 and 590-13 sizes through the Silvertown Classic Bias Ply line, while Firestone is available in 560-13 through the Firestone Classic Bias Ply line.

Brand choice is only part of the decision, since the available tires also vary by sidewall treatment and rim-width specification. The better comparison is to start with the correct size for the car, then look at the sidewall appearance, series character, and wheel compatibility so the final choice fits the Tiara’s setup and intended presentation.

For a period-style 1965 Toyota Tiara, the starting point is one of the original bias-ply fitment sizes, either 560-13 or 590-13, depending on the wheel-and-tire setup on the car. Staying with bias-ply construction keeps the vintage sizing format and supports the kind of appearance many restoration-oriented owners want from an early Toyota sedan.

From there, the appearance choice often comes down to proportion and sidewall treatment rather than brand alone. Narrow whitewall and wide whitewall options create different visual effects, and owners pursuing exact originality should compare those details against marque references, period photos, or other vehicle-specific historical sources before making a final decision.

Tire construction has a noticeable effect on the look of a restored 1965 Toyota Tiara because the car was fitted with bias-ply sizes such as 560-13 and 590-13. A bias-ply tire preserves the vintage sizing language and traditional sidewall profile that many collectors associate with a mid-1960s compact import.

A radial-equivalent tire can still be a useful alternative, but it presents the car differently because the size format and visual character are more modern. For owners balancing appearance and road use, construction becomes part of the restoration decision, not just a technical choice about what can mount on a 13-inch wheel.

Yes, modifications can affect tire fitment on a 1965 Toyota Tiara even when the tire still uses a 13-inch rim. Changes such as aftermarket wheels, different wheel widths, suspension alterations, or body and fender work can influence whether a 560-13, 590-13, or radial-equivalent size has the clearance and proportions the car needs.

That is why the actual vehicle should be checked instead of relying only on year and model. A Tiara that sits lower, uses nonstock wheels, or has aged suspension components may behave differently than expected, so steering clearance and tire-to-body clearance deserve attention before putting the car back into regular road use.

Before driving a 1965 Toyota Tiara on new tires, inspect wheel condition, verify proper air pressure, and make sure the chosen tire size matches the wheel diameter and width. It is also wise to check lug hardware, valve stems, and visible clearance around the fenders, steering components, and suspension once the tires are mounted.

Collector cars often spend long periods parked, so the rest of the car deserves attention too. Look for cracked rubber components, loose steering feel, uneven ride height, fluid leaks, and any sign that the old tires masked an underlying chassis issue. A careful short test drive helps confirm that the new setup is behaving normally.

Tires on a collector 1965 Toyota Tiara should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car uses 560-13 or 590-13 tires, watch for sidewall cracking, bulges, cuts, uneven wear, and slow air loss, especially if the car is only driven occasionally.

Storage conditions matter almost as much as mileage on a lightly used car. Keeping the Tiara away from prolonged sunlight, heat, moisture, and ozone sources can help preserve tire condition over time. It is also smart to inspect the tires before each outing rather than assuming low annual mileage means the tires are road-ready.
