1973 Toyota Corona Tires

The 1973 Toyota Corona uses two primary tire sizes: 165R13 in radial construction and 600-13 in bias-ply construction. Both sizes are built for 13-inch rims, but they represent different tire formats and different approaches to how the car is equipped and driven.

Choosing between them starts with confirming what is on the car now, including wheel width and whether the suspension and steering setup have been kept close to stock. A Corona already running radial tires may point you toward 165R13, while a restoration-minded car seeking a more traditional presentation may keep the 600-13 bias-ply size in view.

The 1973 Toyota Corona uses a 13-inch rim diameter with both of its primary tire sizes, 165R13 and 600-13. Rim diameter is the constant, but the tire formats differ, so matching the tire to the wheel involves more than just confirming the 13-inch measurement.

Wheel width still matters before selecting a tire. The available 165R13 radial products are built around wider 13-inch rim fitments than the 600-13 bias-ply options, so an owner should verify the actual wheel on the car rather than relying only on diameter. That check becomes especially important if the Corona has replacement steel wheels or aftermarket wheels.

On a 1973 Toyota Corona, 600-13 is a vintage numeric bias-ply tire size. The 600 indicates an approximate nominal section width of 6.00 inches, and the 13 refers to the rim diameter in inches. It is a traditional bias-ply format rather than a modern metric radial size.

That matters because a 600-13 tire affects both the look and the fitment path of the car. Buyers considering this size often want a more period-style appearance, especially with whitewall sidewall choices. Before selecting it, confirm that the wheel width and the rest of the vehicle setup still suit a bias-ply tire rather than a later radial conversion.

For the 1973 Toyota Corona, 600-13 is a bias-ply tire size. It uses the older numeric sizing system and appears in available products as a bias-ply construction, including whitewall versions in the Silvertown Classic Bias Ply series.

That makes it the more traditional-looking fitment path for this car. Owners choosing 600-13 should think about the overall goal for the Corona, especially if period-style appearance matters. It is also wise to confirm that the wheel width still matches the bias-ply fitment range, particularly if the car has been updated over the years with different wheels or radial tires.

Radial equivalents for the 1973 Toyota Corona's 600-13 bias-ply size include 165R13 as an 80-series metric radial, P165/75R13 as a P-metric 75-series radial, and P175/70R13 as a P-metric 70-series radial. A bias-look radial equivalent is not part of the available equivalent set for this size.

These sizes are useful comparison points, but they are not automatic substitutes. The recommended rim-width range for the equivalents is 4 to 5 inches, so wheel width should be checked first. After that, compare the actual tire and vehicle setup for clearance around the fenders and steering components before making a construction change.

Start by confirming the original bias-ply size on the car and then compare it with the available radial equivalents for 600-13: 165R13, P165/75R13, and P175/70R13. Wheel diameter remains 13 inches, but wheel width and the tire's overall physical fit still need to be verified before changing constructions.

A conversion also deserves a close look at suspension condition, steering response, and fender clearance, especially on an older compact car that may have seen replacement parts or alignment changes over time. Keep the Corona's intended use in mind as well, because a radial conversion changes the character of the setup even when the tire size remains within the correct fitment family.

The biggest decision is whether the car should stay with the 600-13 bias-ply fitment or use the 165R13 radial fitment. After that, compare the details that actually affect selection, including wheel width, tire construction, sidewall style, tire series, and whether the car is being kept in a more restoration-oriented presentation or driven with radial expectations.

A practical choice starts with the actual wheel and suspension setup on the Corona today, not just what may have been used years ago. A 600-13 bias-ply can support a more traditional look, while 165R13 opens radial choices from Michelin and Dunlop. Matching the tire to the car's current configuration prevents unnecessary compromises in fitment and appearance.

The available sidewall styles for the 1973 Toyota Corona depend on tire size and construction. The 165R13 radial options are blackwall tires, while the 600-13 bias-ply options are offered with either a narrow whitewall or a wide whitewall.

That makes sidewall choice an appearance decision tied closely to construction. A buyer looking for a cleaner radial look will naturally focus on blackwall 165R13 choices, while someone aiming for a more vintage visual presentation may prefer one of the whitewall 600-13 tires. The best match depends on the Corona's overall style, wheel setup, and restoration direction.

Tires for the 1973 Toyota Corona are available from Michelin, Dunlop, and BFGoodrich. Michelin and Dunlop cover the 165R13 radial fitment, while BFGoodrich covers the 600-13 bias-ply fitment with whitewall options in the Silvertown Classic Bias Ply series.

Brand choice should be considered alongside construction, sidewall style, and tire series rather than treated as the only decision. Michelin and Dunlop choices keep the focus on blackwall radial presentation, while BFGoodrich serves the traditional bias-ply side of the fitment. Start with the correct size and wheel compatibility, then compare the brand and series options that remain.

For a period-style 1973 Toyota Corona, the 600-13 bias-ply size is usually the most visually traditional starting point. In the available choices, that size appears in the Silvertown Classic Bias Ply series with whitewall treatments, which gives the car a distinctly vintage presentation compared with the blackwall radial options in 165R13.

That does not automatically make every 600-13 the exact original tire for every car, so owners pursuing strict authenticity should compare the tire choice with marque references and restoration documentation. For many buyers, though, the practical decision is simpler: select the construction and sidewall look that best matches the Corona's era and the level of originality being pursued.

On a restored 1973 Toyota Corona, tire construction changes the visual character of the car as much as the driving setup. The 600-13 bias-ply fitment gives a more traditional vintage impression, especially with narrow or wide whitewall styling, while the 165R13 radial fitment presents a more modernized blackwall look.

That visual difference matters on a compact sedan where wheel and tire proportions are easy to notice. Buyers restoring for a period-style appearance often keep construction and sidewall treatment in the same conversation rather than treating them as separate decisions. The right choice depends on whether the Corona is being finished as a traditional restoration, a preserved driver, or a more updated road car.

Yes, modifications can affect tire fitment on a 1973 Toyota Corona even when the tire size itself falls within the correct family. Wheel changes, altered wheel width, suspension work, ride-height changes, or body modifications can all change how a 165R13 or 600-13 tire sits in the car.

That is why the actual car should be checked before finalizing a tire choice. A Corona with replacement wheels may need closer attention to rim width, and a car with suspension changes may need extra clearance checks at full steering lock and under compression. Older imports often lead varied lives, so present-day setup matters more than assumptions.

Before driving a 1973 Toyota Corona on new tires, inspect the wheels, valve stems, and overall condition of the suspension and steering components. Confirm that the tire size matches the wheel and that there is no obvious interference around the fenders, inner wheelhouses, or steering parts once the tires are mounted.

It also helps to verify tire pressure, look for any uneven ride height, and recheck lug hardware after installation. On an older car that may not be driven every day, a short, careful road test is a smart next step. That lets the owner listen for rubbing, feel for unusual tracking, and make sure the car settles normally on the new tires.

Tires on a collector 1973 Toyota Corona should be checked regularly for air pressure, visible cracking, tread condition, bulges, cuts, and signs of air loss. Low-use cars often age their tires by time and storage conditions rather than by mileage, so appearance alone should not be the only measure of road readiness.

Good storage habits make a real difference. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve both radial and bias-ply tires. It is also worth inspecting the tires before every longer drive, because a Corona that spends most of its time parked can still develop age-related issues between outings.
