1971 Renault Tire Fitment Guide

1971 Renault vehicles use four sizes: 155R13, 560-13, 155R14, and 520-14. The 155R13 and 560-13 sizes fit 13-inch wheels, while 155R14 and 520-14 fit 14-inch wheels. Radial choices are the two 155R metric sizes, and bias-ply choices are the two numeric sizes. Rim width guidance appears on several products, including 4.00 to 5.50 inches for 155R13, 3.50 to 4.50 inches across 560-13 products, 4.00 to 5.50 inches for 155R14, and 3.50 to 4.00 inches for 520-14 products.

That means year and make alone are not enough to choose a tire for a 1971 Renault. You need to verify whether the car has 13-inch or 14-inch wheels before narrowing the construction type. Once wheel diameter is confirmed, the decision becomes simpler: pick the metric radial if you want a later-style radial layout, or the numeric bias-ply if you are keeping a more traditional period presentation.

On a 1971 Renault, 560-13 is a numeric bias-ply size. The 5.60 figure refers to the tire’s nominal section width in inches, written without a decimal point in the code, and the 13 refers to the wheel diameter in inches. Because there is no R in the size, it is a bias-ply rather than a radial. In the available 560-13 range, sidewall choices include narrow whitewall and wide whitewall styles.

That size code matters because it points you toward a traditional construction and a distinctly vintage look. A 1971 Renault on 560-13 tires will present differently than the same car on a blackwall metric radial, even when the wheel diameter is still 13 inches. If your goal is visual authenticity or a classic whitewall treatment, 560-13 is the size family to examine more closely.

On a 1971 Renault, 155R13 and 155R14 are metric radial sizes. The 155 identifies a nominal section width of 155 millimeters, the R indicates radial construction, and the final number is the rim diameter in inches: 13 or 14. Because no aspect ratio is printed in the code, these sizes are conventionally understood as euro-metric 80-series radials. The 1971 Renault radial options are offered in blackwall form.

This code tells you two important things right away: the tire is radial, and it is tied to a specific wheel diameter. A 155R13 cannot replace a 155R14 without changing wheels, even though the section width is the same. For a driver trying to keep a 1971 Renault in an era-appropriate imported-car format while using radial construction, these metric sizes are usually the most recognizable starting point.

For a 1971 Renault with 13-inch wheels, the choice between 560-13 and 155R13 is primarily a choice between bias-ply and radial construction. The 560-13 is a traditional numeric bias-ply size and is available with whitewall styling, while the 155R13 is a metric radial offered as a blackwall. The radial products in 155R13 include H-rated versions with a 130 mph ceiling, which helps define the tire’s intended road use without changing the wheel diameter.

Owners usually make this choice based on how they want the car to look and feel. A 560-13 suits a more period-style presentation, especially if whitewall appearance matters, while a 155R13 keeps the car in a metric radial format that aligns with the era when many European cars were transitioning to radials. Confirm your existing wheel width before making the final call, since the supported rim-width ranges are not identical.

1971 Renault tire choices include both blackwall and whitewall sidewall styles, but the style depends on the size. The radial metric sizes, 155R13 and 155R14, are blackwall offerings. The 560-13 bias-ply size comes in narrow whitewall and wide whitewall form, while the 520-14 bias-ply size is offered in narrow whitewall form. That split lines up with the period distinction between European-style radial blackwalls and more traditional bias-ply whitewall presentations.

For most restorations, sidewall style is just as visible as the size code itself. A blackwall radial often looks right on a practical European car, while a whitewall bias-ply can push the appearance toward a more period-custom or show-oriented finish. If your 1971 Renault will be judged for authenticity, confirm what is correct for your market and configuration before choosing a whitewall width purely for style.

1971 Renault tire options come from Michelin, Dunlop, BFGoodrich, Firestone, and Premium Sport, depending on size. Michelin and Dunlop cover 155R13, Michelin and Firestone cover 155R14, BFGoodrich and Firestone cover 560-13, and Premium Sport covers 520-14. The brand mix also follows the construction split, with Michelin and Dunlop appearing in the metric radial sizes and BFGoodrich, Firestone, and Premium Sport appearing in the bias-ply sizes.

That matters because brand choice on a 1971 Renault is closely tied to the kind of tire you want, not just the badge on the sidewall. If you are focused on a European-style radial format, you will likely spend your time comparing Michelin, Dunlop, and Firestone depending on wheel diameter. If you are chasing bias-ply stance and whitewall presentation, the comparison shifts toward BFGoodrich, Firestone, or Premium Sport.

Rim-width guidance for 1971 Renault tires varies by size. The 155R13 radial fits 4.00 to 5.50-inch rims on products that carry width guidance, while 560-13 bias-ply products span 3.50 to 4.50 inches depending on brand. The 155R14 radial uses 4.00 to 5.50-inch rims where width guidance is stated, and 520-14 bias-ply products with full fitment detail use 3.50 to 4.00-inch rims.

Those ranges are the reason wheel diameter alone is not the whole story on a 1971 Renault. A tire may mount to the correct 13-inch or 14-inch rim and still not be the best match for your wheel width. Measuring the wheel before ordering is especially worthwhile if the car has been restored, modified, or converted from one construction type to another at some point in its life.

Inner-tube status on 1971 Renault tires varies by product. Michelin’s 155HR13 and Michelin’s 155R14 carry TL markings, which identify them as tubeless tires, while other products in those same sizes do not present the marking the same way. The bias-ply sizes do not carry a uniform tube marking across the range either, so there is no single rule that covers every 1971 Renault tire choice.

The practical answer is to check the exact sidewall marking and the wheel itself before installation. Even when a tire is tubeless in design, an original wheel’s condition and bead-seat design still matter on an older car. If your 1971 Renault retains older wheels or has any question about airtight sealing, that is the moment to involve an installer who is comfortable with vintage import applications.

A 1971 Renault stores best in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, and other ozone sources that accelerate sidewall aging. Keep the tires properly inflated, avoid long-term contact with standing moisture, and move the car periodically so one patch of tread is not carrying the load for months at a time. Bias-ply tires are especially prone to temporary flat-spotting during storage compared with radials.

Storage habits affect how a collector car feels the next time it goes back on the road. If your 1971 Renault sits for extended periods, short monthly movement or the careful use of stands can help reduce stress on the carcass and sidewalls. A breathable car cover, clean floor, and stable temperatures do more for tire life than occasional driving after long neglect.

Tire life on a 1971 Renault is usually better judged by age than by miles. Collector-car tires often age out before they wear out, so a sensible rule is to inspect them closely once they reach five to seven years of service and to treat about ten years as the point for serious replacement consideration regardless of remaining tread. The DOT date code on the tire helps establish when the tire was made.

That age-based approach matters because a lightly used 1971 Renault can still be riding on tires that look decent at a glance but have begun to harden, crack, or lose structural resilience. Storage conditions, inflation habits, and exposure to heat all influence how fast that happens. If the car has recently changed hands, confirming tire age is one of the smartest first checks you can make.

Tires on a 1971 Renault should be inspected before every drive and again before any longer outing. Check inflation, tread wear, embedded debris, sidewall cracking, cuts, bulges, and any sign that the tire has been rubbing the wheelhouse or suspension. If your Renault uses a tube-type setup or older wheel hardware, valve stems and slow pressure loss deserve extra attention as part of the routine.

Frequent inspection is especially important on an older import because the car may spend more time parked than driven. Problems that start small, such as minor cracking or a weak valve stem, often show themselves only after the first miles of use or after the car warms up at road speed. A two-minute walkaround can prevent a much larger interruption once the trip is underway.

A 1971 Renault sat in a transitional period when both bias-ply and radial fitments could appear depending on market, model configuration, and wheel package. The sizes associated with 1971 Renault applications here include both numeric bias-ply sizes, 560-13 and 520-14, and metric radial sizes, 155R13 and 155R14. That broad mix fits what enthusiasts expect from early-1970s European small cars, which were moving decisively into radial territory while still overlapping with older bias-ply practice.

For a factory-correct restoration, the safest path is to confirm the wheel diameter on the car and then compare surviving placards, manuals, or marque-club references for your exact market version. Original-equipment brand assumptions can be misleading, so it is better to match the correct size, construction, and sidewall character first. A Renault club or French-car specialist can help settle details when authenticity standards are strict.

Correct tire fitment absolutely matters when a 1971 Renault is judged for originality. Judges and informed enthusiasts notice the size family, whether the tire is bias-ply or radial, and whether the sidewall treatment looks appropriate for the car’s era and market character. A blackwall metric radial and a whitewall bias-ply can create very different impressions even if both fit the same general vehicle family.

That does not mean every event uses the same standard. Some local shows reward overall presentation, while stricter marque or concours events can scrutinize construction and sidewall style much more closely. If your 1971 Renault is being prepared for judged competition, confirm the expected tire appearance in advance so the car’s stance and sidewall treatment support the restoration rather than distracting from it.

For a 1971 Renault in 155R13, Michelin XAS and Dunlop SP Sport Aquajet are both blackwall radial choices with H speed ratings, which carry a 130 mph ceiling. The Michelin uses the 155HR13 78H TL marking and fits 4.00 to 5.50-inch rims, while the Dunlop appears as 155R13 78H and carries a 937-pound load figure. Both weigh 20 pounds, so the main differences are in series design, sidewall marking details, and the way fitment information is presented.

That makes this comparison less about raw category changes and more about choosing the particular radial character you want within the same size. If tube marking, brand heritage, or wheel-width compatibility is a deciding factor for your 1971 Renault, those details are worth checking before installation. It is also wise to compare the exact sidewall wording if you care about how the tire will look on a show-oriented car.

1971 Renault tires can be suitable for highway driving when the size, construction, age, and condition all match the car’s intended use. The radial options include H-rated 155R13 products with a 130 mph ceiling and a T-rated 155R14 product with a 118 mph ceiling. Bias-ply options are also viable when properly fitted and maintained, but they deliver an older driving feel than radial construction, which is worth remembering on a small early-1970s car.

In real use, the vehicle’s own mechanical condition usually matters at least as much as the tire’s published speed capability. Brakes, steering, wheel bearings, alignment, and suspension condition all influence whether a 1971 Renault feels composed on modern roads. If the car is newly restored or recently awakened from storage, treat the first longer highway outing as a shakedown rather than assuming the tires are the only concern.

Inflation pressure on a 1971 Renault should follow the car’s factory recommendation first, then be checked against the tire’s own construction and rated limits. Several sizes carry load-and-pressure figures on the tire side: 560-13 reaches 850 pounds at 30 psi, 155R14 reaches 990 pounds at 44 psi on one product, and 520-14 reaches 1,230 pounds at 60 psi on products that include full load information. Those figures are tire capacities, not a universal instruction to inflate every Renault tire to the maximum value shown.

The best practice is to use the owner’s manual or door-jamb guidance for baseline pressure, then confirm the tire manufacturer’s recommendations if you are changing construction type or moving to a reproduction tire. A radial conversion and a bias-ply setup may not want the same running pressure even on the same car. Keep all four tires matched side to side and recheck them when the seasons change.

Before a longer drive in a 1971 Renault, inspect the tires for sidewall cracking, cuts, bulges, tread separation, irregular wear, and proper cold inflation pressure. Look closely at valve stems, and if the car uses a tube-type arrangement, make sure any history of slow leaks has been addressed. The spare tire deserves the same attention, since a decades-old spare can be unusable even when it has never touched the road.

Tires are only one part of the pre-trip checklist on a vintage Renault. Wheel fastener torque, brake feel, steering play, fluid levels, and charging-system behavior all matter before the car is asked to run at sustained speed. Taking ten extra minutes in the garage can reveal a problem while it is still easy to solve, instead of turning a pleasant drive into a roadside repair.
