The 1971 Nissan 240 sits at the beginning of Nissan’s early Z-car story, blending sports-car proportions, responsive road manners, and the kind of straightforward mechanical character that still appeals to drivers and restorers. Tire choice on this car is refreshingly focused, because the 1971 Nissan 240 uses a single primary radial size, 175R14, on a 14-inch rim. That keeps the fitment question simple and shifts attention toward the type of radial you want, including differences in brand, tire series, and period-appropriate blackwall presentation. For a car valued both for driving enjoyment and careful preservation, the right choice comes down to matching the size, wheel fit, and visual character to the way the car is actually used.
Which Tire Size Is Right for The 1971 Nissan 240
The 1971 Nissan 240 uses one primary tire size: 175R14 radial on a 14-inch rim. The 1971 Nissan 240 Z shares that same fitment, so the main decision is not between multiple original sizes, but between the available 175R14-style radials, their brand character, and how closely you want the tire’s appearance and feel to suit a period-minded sports car.
A 175R14 size uses a nominal section width of 175 millimeters, radial construction, and a 14-inch rim diameter, with this format commonly associated with an 80-series profile. On the 1971 Nissan 240, that makes it a classic radial fitment rather than a later low-profile conversion. Available choices include blackwall options from Michelin and Vredestein across XAS, Sprint Plus, and Sprint Classic series, giving the size some meaningful variation in brand character and product details. For most owners, the real task is choosing the 175R14 that best matches the car’s wheel width, intended road use, and desired period-style presentation.
Fitment is straightforward for the covered 1971 Nissan 240 sub-model. The main value in checking the sub-model is simply confirming that the car is a 240 Z and then selecting the right 175R14 radial within the available product choices.

1971 Nissan 240 Z
The 1971 Nissan 240 Z uses the same 175R14 radial fitment found on the model core, so there is no split in primary tire size within the covered setup. That keeps selection focused on choosing the right blackwall radial by brand, tire series, and wheel compatibility rather than sorting through multiple original fitments.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1971 Nissan 240?
The 1971 Nissan 240 uses a 175R14 radial tire. That is the primary fitment for the covered 240 Z application, so the size question is fairly direct compared with vehicles that split fitment by trim or wheel package.
A 175R14 uses a 14-inch rim, so the next step is confirming that the car still has the correct wheel diameter and an appropriate wheel width for the tire being considered. If the car has aftermarket wheels or a modified suspension, check clearance at the fenders and steering stops before settling on any replacement tire.
What size rim does a 1971 Nissan 240 use?
The 1971 Nissan 240 uses a 14-inch rim with its 175R14 tire fitment. Product offerings in this size also reflect 14-inch wheel use, which keeps the basic diameter match straightforward when replacing worn tires with another tire in the same size family.
Rim diameter alone is not the whole fitment story, so it is still worth checking actual wheel width before choosing among available 175R14 radials. Some products in this size call for a wheel width range of 4.5 to 6.0 inches, which matters when the car has replacement wheels or wheels that may not match original dimensions.
Does the 1971 Nissan 240 Z use the same tire size?
Yes. The 1971 Nissan 240 Z uses the same 175R14 radial size as the model core, so there is no separate primary tire size to sort out within the covered sub-model fitment. That makes the search simpler than on vehicles where trim or package changes alter tire size.
Since the size stays the same, the real choice is which 175R14 radial best suits the car’s intended use and presentation. Owners restoring a period-style street car may pay closer attention to tire series and visual character, while a driver-focused car may place more emphasis on wheel-width compatibility, tire age, and overall condition.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1971 Nissan 240?
Start with the correct 175R14 size, radial construction, and 14-inch wheel diameter, then compare the details that separate one product from another. For this car, available choices differ by brand, tire series, weight, and in some cases rim-width guidance and load specification.
That means the best comparison is practical rather than promotional. Match the tire to the wheel already on the car, think about whether the car is driven regularly or preserved as a collector vehicle, and decide how important a period-style sports-car look is. A careful choice balances correct size, wheel compatibility, and the visual tone you want the car to carry.
What sidewall styles are available for 1971 Nissan 240 tires?
The available 175R14 options for the 1971 Nissan 240 use a blackwall sidewall style. That suits the car’s clean early-1970s sports-car character and keeps the appearance understated rather than adding whitewalls, stripes, or raised-letter treatments.
For many owners, that makes sidewall choice simple and shifts the decision toward brand and tire series instead. Blackwall tires can still vary in overall look through tread design, shoulder shape, and casing profile, so appearance-minded buyers should compare the available 175R14 offerings closely if the goal is a more period-style presentation.
What brands offer tires for the 1971 Nissan 240?
Michelin and Vredestein both offer tires in the 175R14 fitment used on the 1971 Nissan 240. Within those brands, the available series include Michelin XAS plus Vredestein Sprint Plus and Sprint Classic, all in blackwall radial form.
Brand alone should not be the only deciding factor. Compare the specific series, check whether the wheel width on the car matches the tire’s fitment requirements, and look at details such as load specification where available. On a vintage sports car, the right choice is usually the one that keeps the correct size while matching the car’s intended use and visual style.
Restoration & Appearance
Which tire should I choose for a period-style 1971 Nissan 240?
A period-style 1971 Nissan 240 should begin with the correct 175R14 radial size on a 14-inch rim. From there, the most appropriate choice usually comes down to selecting a radial that maintains a traditional sports-car look rather than moving away from the original sizing theme.
Michelin XAS and Vredestein Sprint Classic are the kinds of series that often appeal to restoration-minded buyers because they keep the vintage-size approach intact. When exact originality matters, it is wise to compare against marque references, period photography, or build-specific documentation so appearance decisions support the car’s history rather than just its dimensions.
How does tire construction affect the appearance of a restored 1971 Nissan 240?
On the 1971 Nissan 240, radial construction is part of the vehicle’s primary tire fitment story, so staying with a 175R14 radial preserves the overall visual proportion intended by that size. The available blackwall presentation also keeps the car’s look clean, restrained, and appropriately sporting.
Appearance is influenced by more than the word radial on the sidewall. Tire series, shoulder shape, and the way the tire fills the wheel opening all affect how authentic or out-of-place the finished car feels. Keeping the correct size and avoiding a modern low-profile look usually does more for restoration character than chasing a more aggressive stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 Nissan 240?
Yes. Even though the primary fitment is a straightforward 175R14 on a 14-inch rim, modifications can change whether that size works the same way on a particular car. Aftermarket wheels, altered wheel width, suspension changes, or body modifications can all affect practical tire fitment.
A modified car should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before new tires are mounted. Ride height changes can also alter how the tire sits in the wheel opening. On a vintage sports car, a small change in wheel setup can matter, so it pays to confirm the actual hardware on the car instead of assuming stock dimensions.
What should I inspect before driving a 1971 Nissan 240 on new tires?
Before driving a 1971 Nissan 240 on new tires, inspect the wheels for damage, confirm lug hardware condition, and make sure the tire size matches the car’s 175R14 fitment. It is also smart to check inflation, valve stems, and whether the tires seat properly on the wheels being used.
The rest of the car deserves attention as well, especially on a collector vehicle that may sit for long periods. Look over suspension wear, steering play, brake condition, and any signs of rubbing once the car is back on the ground. A short, careful test drive followed by a recheck for clearance and air retention helps catch problems before regular road use.
How should 175R14 tires on a collector 1971 Nissan 240 be maintained?
175R14 tires on a collector 1971 Nissan 240 should be maintained with regular pressure checks, periodic visual inspections, and attention to age as well as tread depth. Cars that are driven infrequently can develop tire issues from sitting, even when the tread still looks usable.
Storage conditions matter on an older sports car. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect for cracking, bulges, cuts, or air loss before each outing. Rotating use, keeping the car on proper inflation, and checking the tires before longer drives will do more to preserve safe road manners than mileage alone.
