1973 Toyota Tire Fitment Guide

1973 Toyota vehicles use eight sizes across six model lines. Carina, Celica, Corona, and Mark II use either 165R13 radial or 600-13 bias-ply on 13-inch rims. Corolla uses 155R12 or 6.00-12 on 12-inch rims, or 155R13 or 6.15-13 on 13-inch rims. Land Cruiser uses 760-15 or H78-15, both on 15-inch rims. Rim-width guidance appears on some sizes as well: 165R13 fits 4.50 to 6.00-inch rims, 600-13 fits 4.00 to 4.50-inch rims, 155R13 fits 4.00 to 5.50-inch rims, 760-15 fits 5.50 to 6.00-inch rims, and H78-15 fits 5.50 to 7.00-inch rims.

That means year and make alone are not enough for a confident tire choice on a 1973 Toyota. Start by identifying the model, then confirm whether it uses a 12-inch, 13-inch, or 15-inch wheel before narrowing the size. On Carina, Celica, Corona, and Mark II, the main choice is between radial and bias-ply construction on the same 13-inch diameter. On Corolla and Land Cruiser, the model and wheel package determine the correct size family first, and only then does sidewall style or brand become the next decision.

On a 1973 Toyota, 600-13 is a numeric bias-ply tire size. The 6.00 figure refers to nominal section width in inches, and the 13 refers to the wheel diameter in inches. In the 1973 Toyota range, 600-13 belongs to Carina, Celica, Corona, and Mark II applications. BFGoodrich offers that size with whitewall variations, which suits the early-1970s passenger-car appearance associated with bias-ply fitments.

Numeric bias-ply sizing reads differently from modern metric sizes, so it helps to think of 600-13 as a classic format rather than a direct modern equivalent. If your 1973 Toyota still has its original-style 13-inch wheels and you are aiming for period presentation, this is the traditional route to investigate. It is still wise to verify the wheel width before final selection, because the available 600-13 products are intended for narrower 13-inch rims than the radial 165R13 alternatives.

On a 1973 Toyota, 165R13 is a metric radial size. The 165 is the section width in millimeters, the R indicates radial construction, and the 13 is the wheel diameter in inches. Because no aspect ratio is printed in the size itself, it is conventionally understood as an 80-series style radial. Carina, Celica, Corona, and Mark II use this size, and available versions appear from Michelin and Dunlop in blackwall form.

That format matters because it places 165R13 in a different era of tire design than 600-13, even though both fit the same 13-inch diameter family on those Toyota passenger models. Owners often compare the two when deciding how they want the car to feel and present. Before settling on 165R13, confirm the actual wheel width and check the tire's full sidewall marking, since tube notation and complete speed marking are not identical across every product in that size.

For a 1973 Toyota Carina, Celica, Corona, or Mark II, the choice between 165R13 and 600-13 is mainly a choice between radial and bias-ply construction on a 13-inch rim. 165R13 is a radial blackwall size from Michelin and Dunlop, while 600-13 is a bias-ply BFGoodrich size with whitewall styling. The radial path generally appeals to owners who want a later tire format, while the bias-ply path is closer to the driving character and appearance many restorers associate with the period.

The best choice depends on what role your 1973 Toyota serves. A show-oriented car or a restoration that emphasizes original-era presentation often points toward 600-13, especially if whitewall styling matters to the finished look. A regularly driven car may push the decision toward 165R13 because it keeps the correct 13-inch fitment while using radial construction. Whichever direction you take, verify the wheel width before ordering, because the supported rim-width ranges are not the same between those two size families.

1973 Toyota tire choices span blackwall, narrow whitewall, and wide whitewall sidewall styles, but the options depend heavily on size. The radial passenger-car sizes 165R13 and 155R13 come in blackwall form. The 600-13 bias-ply size comes in narrow and wide whitewall versions, while 760-15 spans narrow whitewall and wide whitewall choices. H78-15 gives Land Cruiser owners a mix of wide whitewall and blackwall options.

For most 1973 Toyota passenger cars, blackwall radials look more like a later practical driving update, while whitewall bias-ply tires create a stronger period visual statement. Land Cruiser is the outlier, because its truck and utility character can suit either a plain blackwall or a more stylized whitewall depending on the restoration direction. If authenticity matters for show judging, sidewall style can matter nearly as much as size and construction, so compare the finished look you want before narrowing the brand or series.

1973 Toyota fitments are covered by Michelin, Dunlop, BFGoodrich, Coker Classic, Universal Vintage Tire, and STA. Michelin and Dunlop cover the radial passenger-car sizes 165R13 and 155R13. BFGoodrich covers 600-13 and also offers 760-15, while Coker Classic appears on 760-15 and H78-15. Universal Vintage Tire also offers 760-15, and STA covers H78-15 with a blackwall truck-style option.

Brand choice on a 1973 Toyota usually follows the size family first and the visual style second. If you own a Carina, Celica, Corona, or Mark II, your brand choice changes depending on whether you choose radial or bias-ply construction. Corolla owners face the same pattern once the 12-inch or 13-inch wheel diameter is confirmed. Land Cruiser owners have the broadest variety within bias-ply construction, especially if they are comparing more passenger-style whitewall presentation against a more utility-oriented blackwall tire.

Several 1973 Toyota sizes have clear rim-width guidance. 165R13 fits 4.50 to 6.00-inch rims, 600-13 fits 4.00 to 4.50-inch rims, and 155R13 fits 4.00 to 5.50-inch rims. On the Land Cruiser side, 760-15 fits 5.50 to 6.00-inch rims and H78-15 fits 5.50 to 7.00-inch rims. Those ranges show that two tires sharing the same rim diameter do not automatically share the same ideal wheel width.

That distinction matters most on the 13-inch Toyota passenger cars, where a radial and a bias-ply option may both fit the same diameter wheel but expect different width windows. It also matters on Land Cruiser, where H78-15 accepts a broader span than 760-15. Before choosing a tire, measure the wheel or verify its stamped width if possible. Matching diameter alone is not enough, especially when switching between classic numeric bias-ply sizing and later-style radial sizing on the same 1973 Toyota model.

Inner-tube status varies across 1973 Toyota tire choices rather than staying uniform across the range. The 165R13 Michelin products are marked TL, while the Dunlop 165R13 is not marked the same way in its size description. The 155R13 Michelin product is also marked TL, while the Dunlop 155R13 differs in how the sidewall marking is presented. The bias-ply sizes shown here do not carry a universal tube notation across every product name, so tube use should be confirmed on the specific tire you are considering.

The practical takeaway is to avoid assuming that every radial or every bias-ply tire for a 1973 Toyota is automatically tube-type or tubeless. Wheel design, tire construction, and the exact sidewall marking all matter. If your car still wears original wheels, inspect the wheel condition and verify whether the tire is intended to run with or without a tube before mounting. That extra check is especially worthwhile on collector vehicles that may have older wheels, infrequent use, or a mix of replacement parts accumulated over time.

On several 1973 Toyota passenger models, the answer is often yes in terms of rim diameter, but not automatically yes in terms of wheel width. Carina, Celica, Corona, and Mark II can use either 165R13 or 600-13, and both are 13-inch sizes. Corolla can also have both radial and bias-ply alternatives within a given diameter group, either 12-inch or 13-inch depending on the application. The wheel must still fall within the rim-width range suited to the chosen tire.

That means original wheels can sometimes support more than one tire path, but only after you confirm the wheel's actual width. A narrow wheel that is right for a classic bias-ply tire may not be the ideal match for a radial alternative, even though the diameter is correct. If you are converting from one construction type to another on a 1973 Toyota, treat wheel measurement as part of the project rather than an afterthought. It is the simplest way to avoid choosing a size that fits the rim diameter but not the wheel correctly.

A 1973 Toyota should be stored away from direct sunlight, standing moisture, and ozone-producing equipment such as electric motors, welders, or battery chargers. Clean, dry concrete is better than bare ground, and proper inflation should be maintained during storage rather than letting the tires sit soft. Bias-ply tires are more prone to flat-spotting during long static periods, while any collector tire can suffer sidewall aging if the car sits near heat and ozone sources for months at a time.

For a low-use Corolla, Celica, Corona, Carina, Mark II, or Land Cruiser, periodic movement helps distribute the load and reduce one-spot stress on the casing. If the vehicle will be parked for an extended season, some owners use stands or at least roll the vehicle occasionally to change the contact patch. A breathable cover and a stable indoor climate also help. The goal is to preserve both the structure and appearance of the tire so the car is ready to drive without developing avoidable aging damage.

On a 1973 Toyota collector vehicle, tire life is usually governed more by age than by mileage. A reasonable practice is to begin close inspection and professional evaluation around five to seven years of service, then treat the ten-year point as a serious replacement consideration even if tread depth still looks healthy. The DOT date code on the tire sidewall is the key age reference, and it matters whether the car has seen regular use or long inactive storage.

That age-based approach is especially important on vintage Toyotas because many survive as hobby cars that do not wear tires out in the modern commuter sense. A Land Cruiser used occasionally on rough roads and a Celica driven to weekend events may both age their tires more than they consume tread. Cracking, hardening, repeated air loss, or impact damage should shorten the timeline. When in doubt, judge the tire by calendar age, storage history, and condition rather than by miles alone.

Tires on a 1973 Toyota should be inspected before every drive and more carefully before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, embedded debris, and signs that the tire is not holding pressure consistently. On a vehicle with tube-type fitments or uncertain tube usage, valve stems and any signs of slow leakage deserve extra attention. Land Cruiser owners should also watch for casing damage from off-pavement use or long periods at heavy load.

A quick walk-around catches many of the problems that strand collector cars or make them unpleasant to drive. If the car has been parked for weeks, check pressure cold and feel for flat-spotting in the first miles. On a 1973 Toyota that sees infrequent use, annual professional inspection is a smart baseline even when the tires look good at home. It is much easier to address an aging sidewall or damaged valve stem in the garage than on the shoulder of the road.

A 1973 Toyota Celica would have been associated with bias-ply construction as the traditional factory-era standard, although radial fitments were becoming increasingly relevant in the market during the early 1970s. Within the fitments used on 1973 Toyota passenger cars, Celica uses either 600-13 bias-ply or 165R13 radial on 13-inch wheels. That means both constructions belong to the correct period conversation, but the bias-ply size aligns more directly with an original-style presentation for many restorations.

If your goal is strict authenticity, start with the exact model version, market, and surviving wheel details before choosing a tire. A marque club, factory literature, or long-time Toyota specialist can help confirm whether your specific Celica should lean bias-ply or radial for the way it was delivered. The safest restoration approach is to treat construction type, sidewall style, and wheel diameter as a package. That keeps the finished car visually coherent and avoids pairing an authentic-looking wheel with a tire style that feels out of period.

Correct tire fitment absolutely matters when showing a 1973 Toyota, especially at events that judge authenticity rather than just overall condition. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall style match the vehicle's era and intended presentation. A blackwall radial on a restored early-1970s passenger car can create a different impression than a whitewall bias-ply, while a Land Cruiser shown as a utility vehicle may call for a different visual approach again.

The more serious the event, the more important those details become. Even when a tire is mechanically compatible, the wrong sidewall treatment or an obviously later construction can stand out against otherwise accurate paint, trim, and wheel choices. For a 1973 Toyota destined for judged shows, verify the expected standard with a club or event rule set before making the final choice. That small step can prevent expensive rework and helps the vehicle look intentional rather than merely assembled from available parts.

For a 1973 Toyota using 165R13 or 155R13 radial sizes, Michelin XAS-family products and the Dunlop SP Sport Aquajet share the same overall size category and H-speed-rating ceiling of 130 mph where marked, but they are not identical in presentation details. The Michelin entries are marked TL in their full size descriptions and include a defined rim-width range on the products shown here, while the Dunlop entries are blackwall radials with load figures shown on the 165R13 and 155R13 applications. On 165R13, the Dunlop carries a 1,047-pound load figure; on 155R13, it carries 937 pounds.

In practical terms, this is less about one tire being universally better and more about matching the exact product characteristics to your car and priorities. If you are comparing radial options for a Carina, Celica, Corona, Mark II, or applicable Corolla, check the full sidewall marking, intended wheel width, and whether load information matters for how the car is used. For many owners, the decision comes down to brand preference, period look within a radial format, and the details of the specific product rather than a dramatic fitment difference.

1973 Toyota tires can be suitable for highway driving when the correct size is chosen, the tires are in sound condition, and the speed rating is respected. The radial 165R13 and 155R13 products shown here include H-rated examples, which carry a 130 mph ceiling. The bias-ply Land Cruiser H78-15 products also include substantial load capacity figures, though speed ratings are not presented in the same way on those products. On a vintage Toyota, the condition of the car itself often matters as much as the tire's theoretical limit.

A healthy tire cannot overcome tired suspension, worn steering parts, weak brakes, or decades-old wheel issues. For most real-world driving in a 1973 Toyota, normal highway use falls well below the speed capability of the H-rated radial offerings, but that does not remove the need for mechanical inspection. Bias-ply tires also drive differently from radials, especially on crowned roads and in crosswinds, so the driver should expect period behavior rather than modern-car responses. Safe road use starts with a complete, vehicle-wide readiness check, not tire size alone.

Inflation pressure for a 1973 Toyota should follow the vehicle's factory guidance first, then be checked against the tire maker's rated pressure information for the exact tire you are using. Several size families here include maximum load and pressure figures rather than blanket operating recommendations: 600-13 is shown at 1,010 pounds at 32 psi, 760-15 at 1,710 pounds at 32 psi, H78-15 at 1,770 pounds at 32 psi in some versions and 1,830 pounds at 45 psi in the STA version. Those numbers are capacity references, not one universal setting for every Toyota.

That distinction matters because a passenger Corolla, a sporty Celica, and a heavy Land Cruiser do not ask the same thing of a tire, even when two products share a broad vintage format. Do not transfer a pressure figure from one size to another simply because the wheel diameter is similar. Use the owner's manual or factory placard for baseline inflation, then confirm that your chosen reproduction or specialty tire is being used within its allowed range. Pressure should always be checked cold and revisited after long storage.

Before a longer drive in a 1973 Toyota, inspect each tire for cracking, cuts, bulges, tread separation, foreign objects, and uneven wear. Check cold inflation pressure, confirm the spare is usable, and make sure the valve stems are in good condition. If your Toyota runs tube-type tires or a tire with uncertain tube status, verify that any recent service addressed the correct tube and flap requirements. Land Cruiser owners should also look for bruising or impact damage from previous trail or utility use.

That tire inspection should be part of a broader vintage-car check that includes brakes, wheel bearings, steering play, fluid leaks, lights, and cooling-system readiness. A classic Toyota can feel fine around town yet reveal weaknesses once it is asked to run longer and hotter at sustained road speeds. Planning a longer outing also means carrying proper inflation equipment and checking the date code on older spare tires. Good preparation protects the tire investment and makes the drive more enjoyable and far less stressful.
