Nissan 1200 Tires

Nissan 1200 was a compact economy car sold in the early 1970s, a period when small imported cars were becoming a familiar part of American roads and garages. Light weight, simple engineering, and modest wheel-and-tire dimensions are part of what gives Nissan 1200 its character today, especially for owners preserving an honest period driving experience. Tire selection is not entirely straightforward because the same 1971 to 1973 Nissan 1200 listings include both a metric radial size and an older numeric bias-ply size for the same years. The practical first step is to confirm which size format and construction type your particular Nissan 1200 is already set up to use before choosing replacement tires.

Nissan 1200 Tire Size Guide

Nissan 1200 uses 2 distinct tire sizes across the 1971 to 1973 production span. Both sizes share the same model years, which means the key choice is not a year change but the size and construction type that matches the car's current wheel and intended use. One size is a modern-style metric radial code, while the other is an older numeric bias-ply code that reflects an earlier sizing convention.

155R121971-1973Euro-metric radial

155R12 is a radial size used on Nissan 1200 models from 1971 through 1973. The 155 designates section width in millimeters, the R indicates radial construction, and the 12 is the wheel diameter in inches. Choose this size if your Nissan 1200 is set up for radial tires and you want a more modern road feel while still staying within the listed size range.

6.00-121971-1973Numeric bias-ply

6.00-12 is a numeric bias-ply size used on Nissan 1200 models from 1971 through 1973. The 6.00 identifies the nominal section width in inches and the 12 is the wheel diameter in inches, with the dash format indicating bias-ply construction rather than radial. Choose this size if your Nissan 1200 is being kept in a more period-correct bias-ply configuration, and remember that a tube is required.

Nissan 1200 Tires by Year

The year listing for Nissan 1200 shows which sizes apply to each model year and helps narrow the choice between the radial and bias-ply options. All three years list both sizes, so the deciding factor is the specific wheel and tire setup on the car rather than the model year alone. Compare the year entry with the tire already fitted and the wheel diameter stamped or measured on the vehicle before making a final selection.

Frequently Asked Questions

These Nissan 1200 FAQs focus on the two listed size systems, the practical difference between bias-ply and radial construction, and how to identify the right tire for a 1971, 1972, or 1973 car.

Size Basics & Fitment

Nissan 1200 uses two listed tire sizes across the 1971, 1972, and 1973 model years: 155R12 and 6.00-12. The 155R12 size is a radial tire on a 12-inch wheel, while 6.00-12 is a numeric bias-ply size that also fits a 12-inch wheel. There is no year split between them in the listed range, so both sizes appear across all three years.

The practical choice comes down to the car's present configuration and the kind of driving experience you want. A Nissan 1200 already equipped for radial tires should generally stay with the metric radial size, while a restoration aimed at a more period-type bias-ply setup may use the numeric size. Check the existing wheel diameter and compare the current tire markings before changing formats.

On a Nissan 1200, 6.00-12 is a numeric bias-ply size. The 6.00 figure is the nominal section width in inches, and the 12 is the wheel diameter in inches. The dash-style numeric format identifies an older bias-ply sizing system rather than a metric radial designation.

That matters because a 6.00-12 tire is not simply another way of writing 155R12. The two sizes belong to different construction traditions and can give a Nissan 1200 a different look and feel on the road. If your car is a restoration or still carries a traditional bias-ply setup, this is the size format to verify on the sidewall and wheel before replacing tires.

A 1971 Nissan 1200 has 2 tire sizes listed because the same year appears with both 155R12 and 6.00-12. That is a construction and sizing-system split rather than a wheel-diameter change, since both sizes use 12-inch wheels. One is a metric radial size and the other is a numeric bias-ply size.

For an owner, that means the year alone does not settle the choice. You need to identify whether your Nissan 1200 is currently running radial or bias-ply tires and whether the car is being preserved for originality or for more modern road manners. Matching the replacement tire to the wheel, construction type, and intended use will prevent an avoidable fitment mistake.

A Nissan 1200 fitted with the 6.00-12 bias-ply size requires a tube. That tube requirement follows the listed numeric bias-ply construction used for that size. The 155R12 radial size is a separate format and should be matched to the wheel and tire setup already on the car.

Tube fitment is important because tube-type and radial-style applications should not be treated as interchangeable without checking the wheel design and the tire being selected. If your Nissan 1200 is wearing numeric bias-ply tires now, keep the tube requirement in mind when replacing them. This is especially important on a collector car that may see limited use and long storage intervals.

Crossply vs Radial

Nissan 1200 is listed with both a bias-ply option, 6.00-12, and a radial option, 155R12, for the 1971 to 1973 years. That means either construction can be appropriate depending on how the specific car is set up and what the owner wants from it. Bias-ply tires support a more period-style presentation, while radial tires generally align with a more modern driving feel.

The right choice depends on your priorities. A show-oriented Nissan 1200 or one being restored to an earlier appearance may favor the numeric bias-ply size, while a driver intended for regular road use may favor the radial listing. Keep the car consistent rather than switching casually, and confirm the wheel and current tire format before changing construction type.

A Nissan 1200 fitted with 155R12 radial tires can feel different from one running 6.00-12 bias-ply tires because the two constructions behave differently in steering response, tracking, and general ride character. The listed radial size uses a modern construction style, while the numeric size reflects a traditional bias-ply approach. Even when both fit the same 12-inch wheel diameter, they do not deliver the same driving impression.

That change in feel matters most if you know the car well or are trying to preserve a specific period character. An owner moving from bias-ply to radial tires on a Nissan 1200 should expect the car to feel less vintage in its road manners. If originality and era-correct response are the priority, stay with the bias-ply setup rather than changing simply because both sizes are listed.

A Nissan 1200 is listed with both bias-ply and radial fitments, but that does not make mixed construction a good practice on the same car. The 6.00-12 and 155R12 options represent different tire behaviors, and combining them can produce uneven response. Collector vehicles benefit from consistent tire construction across the set.

The safer and more predictable approach is to equip your Nissan 1200 with a matched set of either bias-ply tires or radial tires, depending on the configuration you choose. That keeps steering and handling more uniform and makes the car easier to evaluate during driving and inspection. If the car currently has a mixed set, treat that as a temporary condition to correct rather than a preferred arrangement.

Buying the Right Tire

A 1972 Nissan 1200 can use either 155R12 or 6.00-12, so the correct tire is identified by the car's existing wheel-and-tire setup rather than the year alone. Both sizes use a 12-inch wheel, but one is a radial metric size and the other is a bias-ply numeric size. Reading the sidewall on the current tires is usually the fastest way to see which system the car already uses.

You should also look at the purpose of the car before replacing anything. A Nissan 1200 restored for a period look may call for the bias-ply format, while a regularly driven example may already be configured around the radial size. If the tires on the car do not match front to rear or appear to be a later substitution, compare against original paperwork or a marque specialist's guidance.

No products are listed here by brand for Nissan 1200, so the page's key value is the size guidance rather than a brand comparison. The listed fitments establish that the Nissan 1200 uses either 155R12 or 6.00-12 across the 1971 to 1973 years. Those size and construction details are the first things to settle before evaluating brand choices.

For a buyer, that means the priority is matching the correct format to the car before worrying about nameplates. A Nissan 1200 set up for radial tires should stay within the 155R12 radial category, while a period-style bias-ply car should stay within 6.00-12. Once the size and construction are confirmed, brand selection becomes a narrower and more useful discussion.

The listed Nissan 1200 fitments show two different sizing and construction approaches rather than a long list of series names: 155R12 as a radial format and 6.00-12 as a bias-ply format. That distinction matters more than a series label because it affects how the tire is built and how the car presents. The radial size represents a more modern construction style, while the numeric size preserves a more traditional bias-ply character.

When choosing between them, think about whether your Nissan 1200 is a road car, a preservation car, or a judged restoration. Construction style changes both appearance and feel, even when wheel diameter stays the same. Treat the listed sizes as two different approaches to the same model rather than as minor variations of one interchangeable tire type.

Maintenance & Longevity

A Nissan 1200 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, heaters, and petroleum contamination. Whether the car wears 155R12 radials or 6.00-12 bias-ply tires, long static storage is harder on collector tires than regular moderate use. Clean tires and stable inflation matter more than cosmetic dressings.

If the Nissan 1200 will sit for extended periods, move it occasionally or support it in a way that reduces flat-spotting and casing stress. Check inflation before and after storage, and avoid parking for months on damp concrete if possible. Good storage habits protect both appearance and service life, especially on a light classic that may spend much of the year parked.

Tires on a Nissan 1200 should be inspected regularly, not just at annual driving season startup. Look for cracking, tread separation, sidewall damage, irregular wear, and air loss on both 155R12 radial tires and 6.00-12 bias-ply tires. A collector car that sees short drives and long idle periods can develop tire problems even when tread still looks good.

A practical routine is to inspect the Nissan 1200 before every meaningful drive and to do a more careful check several times during the year. Include the spare if the car carries one, and pay attention to valve stems and tube-related issues on bias-ply applications. Catching small changes early is especially important on older small cars that may feel stable until a problem becomes advanced.

A Nissan 1200 tire should be replaced when age, cracking, casing condition, or structural concerns make the tire questionable, even if tread depth still appears usable. Collector tires often age out before they wear out, particularly on cars driven occasionally. That applies to both radial and bias-ply fitments, although bias-ply and tube-type setups deserve especially close attention.

The key point is not to judge a Nissan 1200 tire by tread alone. If the rubber has hardened, the sidewalls show visible age, or the car has been sitting on the same tires for many years, replacement is usually the wiser course. An experienced vintage tire specialist or restoration shop can help evaluate age-related condition when the answer is not obvious at first glance.

Restoration & Authenticity

Nissan 1200 is listed with both 155R12 and 6.00-12 across the 1971 to 1973 years, so there is more than one period-appropriate direction represented in the size range. One reflects a radial metric format and the other a traditional numeric bias-ply format. That means original-equipment style should be confirmed against the specific car rather than assumed from the model name alone.

For restoration work, the best approach is to compare your Nissan 1200 with factory literature, surviving original tires, and marque-club knowledge before choosing between the two. Owners often find that details such as market, trim, and previous restoration decisions affect what is on the car today. Getting that choice right improves both presentation and historical consistency.

Correct tire fitment can affect both the presentation and judged credibility of a Nissan 1200, especially when the car is restored to a period standard. Judges and knowledgeable enthusiasts notice whether a car wears a radial metric size or a traditional bias-ply numeric size, because the visual and historical impression is different. Tire choice is part of the overall story the car tells.

For a Nissan 1200 being prepared for shows or marque events, choose the tire format that best matches the car's restoration objective rather than selecting purely on convenience. If the goal is authenticity, compare the car with period photos, factory references, and club guidance. A well-matched tire size and construction can sharpen the final result without altering the character of the car.

A correct sidewall style for a Nissan 1200 restoration should match the era and the specific restoration goal, but the key first decision is still the tire format itself: 155R12 radial or 6.00-12 bias-ply. Sidewall appearance and construction work together to shape the finished look of the car. A tire can be dimensionally suitable yet still look out of place if the sidewall style does not suit the build.

The most reliable approach is to evaluate surviving originals, period images, and Nissan 1200 enthusiast references before making a final visual choice. Owners aiming for authenticity usually get better results when they decide on size, construction, and sidewall appearance as one package. That keeps the restoration visually coherent instead of mixing a period body style with a noticeably mismatched tire presentation.

Safety & Road Use

A Nissan 1200 can be driven on public roads when the tires are the correct size, in sound condition, properly inflated, and matched to the wheel and construction type the car is using. The listed choices include both 155R12 radial and 6.00-12 bias-ply tires, and each can be appropriate when fitted correctly. Safety depends as much on condition, age, and consistency as on nominal size.

Before road use, make sure your Nissan 1200 is on a matched set rather than a mixture of radial and bias-ply tires. Also inspect the brakes, steering, suspension, and wheel hardware, since an older small car places noticeable demands on every chassis system. Tire choice is only one part of making the car roadworthy, but it is one of the most visible and easiest to overlook.

Before driving a Nissan 1200, check tire pressure, visible sidewall condition, tread condition, and whether all four tires are the same size and construction type. Confirm that the car is consistently fitted with either the 155R12 radial size or the 6.00-12 bias-ply size, rather than a mix. On a bias-ply setup, tube-related condition also deserves attention.

A short walk-around catches many of the problems that develop on collector cars between drives. Look for cracking, bulges, low inflation, and signs that the car has been sitting on one spot too long. If the Nissan 1200 has been stored for an extended period, give it a more thorough inspection before normal road use instead of assuming the tires are ready simply because they still hold air.

A sensible speed for a Nissan 1200 on period-type tires is one that respects the age, construction, and overall condition of both the tires and the car. A 6.00-12 bias-ply setup should be driven with more caution than a modern-feeling radial setup, even though both sizes are listed for the same years. Condition matters more than appearance, especially on a collector car that may not be used regularly.

The practical rule is to let the car tell you what it is comfortable doing and to avoid sustained high-speed driving unless the entire Nissan 1200 has been carefully prepared for it. Smooth roads, moderate speeds, and conservative use are kinder to older tires and older mechanical systems alike. If there is any doubt about age or structural condition, keep speeds down until the tires have been professionally evaluated.
