Nissan 240 Tires

Nissan 240 uses one tire size across the 1971, 1972, and 1973 model years: 175R14. The available products in that fitment include 175R14 and 175HR14 radial tires, all built for 14-inch rims. In practical terms, the size family remains the same across the full production span covered here, with no year-to-year rim diameter change shown.

That makes year identification easier, but the car should still be checked in the garage before choosing a tire. Confirm that the wheels are still 14-inch units and compare wheel width against the tire’s approved range, especially if the car has been restored or modified over time. On an early Nissan sports car, those details matter as much as the size printed on the sidewall.

On Nissan 240, 175R14 is a metric radial size. The 175 refers to nominal section width in millimeters, the R indicates radial construction, and the 14 means the tire fits a 14-inch wheel. Listings shown as 175HR14 add a speed rating designation while keeping the same basic size and 14-inch rim fitment.

That means a buyer should focus first on matching the 14-inch wheel and the 175-width size family, then compare the individual tire’s construction details and wheel-width suitability. If the goal is a period-correct appearance with modern radial road manners, the 175R14 and 175HR14 offerings are the right place to concentrate rather than trying to translate the car into a later low-profile metric size.

Nissan 240 uses a 14-inch rim diameter throughout the 1971 to 1973 range covered here. Every available tire listed for the model fits a 14-inch wheel, and there is no separate wheel-diameter split within these years. That consistency is helpful because it narrows the fitment question to size family and wheel width rather than a year-based rim change.

Even with a single rim diameter, it is worth checking the actual wheels on the car before fitting new tires. Collector cars often pick up replacement wheels during their lives, and a Nissan 240 with aftermarket or later wheels may need a different fitment strategy altogether. The safest approach is to verify the stamping or measurement on the wheel and compare it with the tire’s approved fitment range.

A 1971 Nissan 240 uses 175R14, with available radial products also listed in 175HR14 form on the same 14-inch rim diameter. The main confirmation points are the wheel diameter and the wheel width, since some listings specify approved rim widths from 4.5 to 6.0 inches. Because the model uses one size family across all three years shown, the verification process is more about the actual wheels on the car than about year-specific tire changes.

Start by reading the wheel size on the rim or measuring it if necessary, then compare the car’s existing tire and wheel combination with the new tire’s stated dimensions. If the car has aftermarket wheels, suspension changes, or a restoration history you do not fully know, verify those details before settling on one of the available radials. That extra step helps preserve steering feel and visual balance on an early Nissan 240.

Nissan 240 tires in this fitment are available from Michelin and Vredestein. The current choices shown include the Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic, all in the 175R14 or 175HR14 size family for 14-inch wheels. All of the listed options are radial blackwall tires, which suits the character of a 1970s sports coupe.

Brand choice on Nissan 240 often comes down to how closely the buyer wants to match period appearance, road feel, and sidewall presentation within the available radial offerings. A touring-focused owner may prioritize one series, while a preservation-minded enthusiast may prefer another with a more classic visual profile. Once the size and wheel dimensions are confirmed, comparing the available series is the useful next step.

Nissan 240 has three tire series available in this fitment: Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic. All three are radial tires for 14-inch wheels, but they represent different product families within the collector and classic road-tire space. The XAS and Sprint Classic are often chosen by owners who want a more period-sympathetic look, while Sprint Plus sits as a separate Vredestein radial series in the same size family.

For a Nissan 240 owner, the practical difference is less about basic fit and more about how closely the tire’s design aligns with the car’s intended character. One buyer may want a distinctly vintage visual feel, while another may simply want a quality radial in the correct size family. Once wheel width and 14-inch diameter are confirmed, series selection becomes a matter of appearance and use rather than core compatibility.

A Nissan 240 should be stored in a cool, dry, dark environment with the tires protected from sunlight, ozone sources, and wide temperature swings. Keep the tires inflated to appropriate pressure for storage and avoid letting the car sit for long periods on a dirty or damp surface. Radial tires on collector cars benefit from the same careful storage practices as the rest of the vehicle.

If the Nissan 240 will be parked for an extended season, rolling the car occasionally or supporting it appropriately can help reduce flat spotting and casing stress. Clean tires with mild soap and water only, and avoid dressings that can accelerate drying or cracking. Good storage habits preserve both ride quality and the visual presentation that matters on an early Japanese classic.

Tires on a Nissan 240 should be inspected before every meaningful drive and more thoroughly several times during the year, even if the car covers very few miles. Look for pressure loss, sidewall cracking, tread separation, puncture damage, uneven wear, and any sign that the tire is aging out. Collector cars often spend more time parked than driven, which makes regular visual inspection especially important.

A Nissan 240 that feels fine on a short trip can still have tire issues developing from age, storage, or alignment drift. Check the spare as well, and inspect the valve stems whenever the wheels are off. If anything about the tire’s condition or behavior seems questionable, have the tire and wheel assembly evaluated before putting the car back into normal road use.

Tires on a Nissan 240 should be replaced when age, cracking, hardening, impact damage, persistent air loss, or structural concerns appear, even if the tread still looks usable. Collector-car tires often age out long before they wear out, especially on cars driven only occasionally. Tread depth alone is not a reliable measure of serviceability on a low-mileage classic.

The practical rule is to treat the tire as a safety component, not just a cosmetic one. If the Nissan 240 has sat for years, has visible weathering, or still wears old tires from a prior restoration, replacement should be part of the recommissioning process. A fresh set in the correct 175R14 size family can transform confidence, braking feel, and steering consistency without altering the car’s period character.

Nissan 240 is represented here by a single 175R14 fitment across the 1971 to 1973 years covered, with current replacement choices including Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic. All are radial blackwall tires for 14-inch rims. That establishes the basic size family and construction style used for replacement, but individual cars may still deserve comparison against factory literature, surviving original wheels, and marque references.

For restoration work, the important point is to match the car’s period appearance and wheel dimensions rather than assuming any modern 14-inch tire will look right. The correct section width, sidewall shape, and overall visual proportion are central to how a Nissan 240 sits. Enthusiast clubs and unrestored reference cars can help settle finer originality questions once the correct size family has been identified.

Correct tire fitment can affect both the judged presentation and the market perception of a Nissan 240. On a well-restored early Japanese sports car, the wrong overall size, sidewall profile, or wheel fitment can noticeably change stance and visual authenticity. Staying with the proper 175R14 size family on 14-inch wheels supports the car’s original character in a way oversized or overly modern alternatives do not.

For a driver-quality Nissan 240, that may be mainly a matter of aesthetics and balance. For a high-level restoration, judges and knowledgeable buyers tend to notice whether the tire looks era-appropriate and proportionally correct. If authenticity is a priority, use the tire size as the foundation and then compare available series for the appearance that best suits the level of restoration.

Michelin XAS and Vredestein Sprint Classic are both available for Nissan 240 in the 175HR14 size family, and both are radial blackwall tires for 14-inch wheels. They are separate tire series with different design identities, but each stays within the correct general fitment envelope for the car. The key common ground is that both preserve the proper basic sizing without moving into an obviously later wheel diameter.

For a Nissan 240 owner, the choice usually comes down to which series better matches the desired combination of visual authenticity and road-going character. One restoration may lean toward a particular period presentation, while another may simply want a quality radial from a well-known vintage-focused line. Once the wheel width is confirmed, comparing the look and intent of the two series is the right next step.

Properly fitted modern radial collector tires in the 175R14 or 175HR14 size family can be appropriate for driving a Nissan 240 on public roads when the tires are in sound condition and the rest of the car is equally roadworthy. The available options here are all radial designs for 14-inch rims, which suits normal use of a classic 1970s sports coupe better than aged or mismatched tires. Safety depends on condition, fitment, inflation, and the mechanical state of the car as a whole.

A Nissan 240 should still be treated like a vintage car rather than a modern commuter, especially if it is newly acquired or freshly returned to service. Before regular road use, inspect the brakes, steering, suspension, wheel bearings, and alignment along with the tires. Even the correct tire size cannot compensate for degraded chassis components or decades-old maintenance history.

Before driving a Nissan 240, check tire pressure, sidewall and tread condition, lug security, and any signs of rubbing or uneven wear. Since the correct fitment uses 14-inch radial tires, it also makes sense to verify that all four wheels match and that the tire size family is consistent across the car. A quick walkaround can reveal issues that are easy to miss on a collector vehicle that is not driven every day.

Beyond the tires, look at brake feel, steering response, fluid leaks, and suspension behavior during the first few miles. If the Nissan 240 has been parked for an extended period, treat the first drive as a recommissioning exercise rather than a normal outing. Small problems tend to show up quickly once the car is moving again, and catching them early helps protect both the tires and the car.

A Nissan 240 should be driven at speeds appropriate to the condition of its tires, wheels, suspension, brakes, and overall mechanical health rather than by age alone. The listed replacements are modern radial tires in the correct size family, which are better suited to normal classic-car road use than old, hardened, or unknown-age tires. Even so, the car remains an early-1970s sports coupe with vintage chassis behavior and should be driven accordingly.

The practical approach is to build speed gradually after confirming balance, alignment, and stable road manners. If the Nissan 240 is on newly fitted tires, use the first drives to evaluate steering feel, straight-line tracking, and brake response before attempting extended highway use. A classic car that feels composed at moderate speeds is giving you useful information about whether the whole package is ready for more.
