The 1973 Nissan 240 sits in the early Japanese sports-car era that helped establish a strong following for lightweight, driver-focused coupes with European-influenced proportions and everyday usability. For many owners, the appeal is not just the shape of the car, but preserving the balanced character that made it so enjoyable on the road. Tire fitment for the 1973 Nissan 240 centers on a 175R14 radial on a 14-inch rim, keeping the decision focused on selecting the right radial within the correct vintage format. Available choices lean toward blackwall presentation, with Michelin and Vredestein options that suit restoration-minded cars as well as regularly driven examples.
Which Tire Size Is Right for The 1973 Nissan 240
The 1973 Nissan 240 uses one primary tire size: 175R14. It is a radial fitment on a 14-inch rim, and the covered 240 Z sub-model uses that same size, so the main decision is not between multiple fitments but between the available radial tires, their vintage-style character, and the rim-width compatibility that best matches your wheels.
A 175R14 size uses a 175-millimeter nominal section width, radial construction, and a 14-inch rim diameter, with this format commonly associated with an 80-series profile even though the aspect ratio is not stated in the size itself. For the 1973 Nissan 240, that makes it a proper period radial fitment rather than a later low-profile conversion. Available choices include Michelin and Vredestein products in blackwall form, with series such as Michelin XAS, Sprint Plus, and Sprint Classic. The key is choosing a tire that suits the car's intended appearance, road use, and wheel width before mounting.
Sub-model fitment is straightforward for the 1973 Nissan 240 covered here. The 240 Z uses the same primary tire size, so the focus stays on selecting the right radial tire within that fitment rather than sorting through multiple size combinations.

Best 1973 Nissan 240 Tires for Sale
Available 175R14 choices for the 1973 Nissan 240 include Michelin and Vredestein radial tires in blackwall form. The main differences in the product grid come from tire series, rim-width compatibility where stated, and the balance between period-style presentation and road-use priorities.
Common questions for the 1973 Nissan 240 usually center on the 175R14 fitment, 14-inch wheel compatibility, choosing between Michelin and Vredestein offerings, and checking an older sports car carefully before putting fresh tires into regular road use.
Tire Size & Fitment
What tire size fits a 1973 Nissan 240?
The 1973 Nissan 240 uses a 175R14 radial tire. That size is the core fitment for this application and keeps the car in a vintage Euro-metric radial format that suits its early-1970s sports-car character.
The practical decision is choosing the right 175R14 tire rather than sorting through several primary sizes. Before ordering, confirm that the car still has 14-inch wheels and that any past wheel changes have not altered the rim width or overall setup, since an older 240 may no longer be on its original wheel configuration.
What size rim does a 1973 Nissan 240 use?
The 1973 Nissan 240 uses a 14-inch rim with its 175R14 tire fitment. Product specifications in this size also show fitment on 14-inch wheels, which is the rim diameter tied to this application.
Rim diameter is only part of the check. Some 175R14 tires also state rim-width compatibility, including 4.5- to 6.0-inch applications, so it is worth measuring the wheel before choosing between available products. That matters especially on a car that may have had aftermarket wheels installed at some point in its life.
Does the 1973 Nissan 240 Z use the same tire size?
Yes. The 1973 Nissan 240 Z uses the same 175R14 radial tire size. That makes sub-model fitment simple for this vehicle and keeps the tire search focused on selecting the right version of that one size.
Even with shared size fitment, wheel condition and actual wheel dimensions still deserve a close look. A Z that has been restored, modified, or sitting for long periods may have replacement wheels, aged valve stems, or other issues that affect mounting and road readiness, so verifying the wheel setup remains an important step.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1973 Nissan 240?
Start with the correct size, which is 175R14, and then compare the available radial choices by tire series, rim-width compatibility where stated, and the kind of driving the car actually sees. For this fitment, options include Michelin XAS and Vredestein offerings such as Sprint Plus and Sprint Classic.
A restoration-minded car may call for a tire with a more traditional presentation, while a regularly driven 240 may lead you toward a particular series based on construction details and wheel compatibility. Looking at weight and load specifications can also help narrow the choices without turning the decision into a simple brand comparison.
What sidewall styles are available for 1973 Nissan 240 tires?
The available 175R14 products for the 1973 Nissan 240 use a blackwall sidewall style. That keeps the visual presentation clean and restrained, which suits the car's early sports-car look without introducing whitewall or raised-letter styling.
Since the sidewall treatment is consistent across the available products, the real visual differences come more from the tire series and overall tread-and-profile character than from decorative sidewall elements. That can simplify the selection process for owners who want a period-style appearance without sorting through multiple sidewall treatments.
What brands offer tires for the 1973 Nissan 240?
Michelin and Vredestein both offer tires in the 175R14 fitment for the 1973 Nissan 240. Within those brands, the available series include Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic.
The better way to compare those choices is by the type of tire each series represents, the stated wheel-width range where available, and how the finished look suits the car. Brand alone does not answer the whole fitment question, especially on a collector-oriented sports car where appearance and wheel compatibility both matter.
Restoration & Appearance
Which tire should I choose for a period-style 1973 Nissan 240?
A period-style approach starts with the correct 175R14 radial size. That preserves the proper sizing format for the 1973 Nissan 240 and keeps the car closer to the kind of tire presentation an early-1970s sports coupe would have worn than a later low-profile substitute.
From there, the decision comes down to the available blackwall radial series and how closely their overall character matches your restoration goals. Owners pursuing exact historical authenticity should still compare their car against marque-club guidance or other vehicle-specific references, since period-style appearance is not the same thing as a proven factory-original tire specification.
Does correct tire fitment matter for a 1973 Nissan 240 restoration?
Yes, correct tire fitment matters because the tire size strongly affects the stance and overall visual balance of a 1973 Nissan 240. Staying with the 175R14 radial format helps preserve the car's intended look far better than substituting a noticeably different modern profile.
Fitment also affects how believable the finished restoration feels. Even when the car is not being judged at a high level, the wrong diameter, wheel match, or sidewall presentation can make an otherwise carefully restored 240 look out of character. Confirming wheel size and choosing a suitable blackwall radial keeps the result more cohesive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 Nissan 240?
Yes. A 1973 Nissan 240 may no longer be on its original wheel and suspension setup, and changes to wheel width, wheel offset, ride height, springs, or fender clearance can all affect how a 175R14 tire sits and operates on the car.
That is why the actual wheel dimensions should be confirmed before choosing among the available tires, especially where a product specifies a rim-width range. Steering clearance at full lock and space around the fender openings also deserve attention, since an older sports car can vary quite a bit from one example to another.
What should I inspect before driving a 1973 Nissan 240 on new tires?
Before road use, inspect the wheels for damage or corrosion, verify valve stem condition, and make sure the tires are mounted in the correct 175R14 fitment on proper 14-inch rims. It also helps to look over suspension and steering components on a car that may have spent long periods parked.
Fresh tires cannot compensate for worn tie-rod ends, loose wheel bearings, poor alignment, or old shocks. Check inflation carefully, watch for any rubbing during the first miles, and recheck lug torque after installation. A short local drive is a sensible first step before asking a vintage 240 to handle highway speeds or a longer trip.
How should 175R14 tires on a collector 1973 Nissan 240 be maintained?
175R14 tires on a collector 1973 Nissan 240 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and irregular wear, and protected from long exposure to sunlight, moisture, and ozone sources. Low-use cars still need tire checks even when tread depth looks excellent.
Collector vehicles often age their tires out before they wear them out. Rolling the car occasionally, keeping the wheels clean, and checking for slow air loss can help preserve the tires between drives. Before any seasonal return to the road, give the sidewalls and tread a close inspection and confirm that the tires still match the car's current wheel setup.
