The 1974 Nissan 260 sits at an interesting point in early Z-car history, carrying the long-hood, rear-drive sports car formula that made Nissan's S30 chassis such a favorite with collectors and drivers alike. For owners trying to keep that balanced, lightweight character intact, tire choice matters as much as appearance. The 1974 Nissan 260 uses a 175R14 radial tire on a 14-inch rim, so the decision is less about sorting through multiple factory sizes and more about choosing the right radial within that fitment. Available options include blackwall tires from Michelin and Vredestein in different series, making it important to balance period-style presentation, wheel compatibility, and real road use.
Which Tire Size Is Right for The 1974 Nissan 260
The 1974 Nissan 260 uses one primary tire size: 175R14, a radial fitment for a 14-inch rim. The 260 Z shares that same size, so the key decision is choosing the right tire within that fitment, including brand, tire series, and the kind of period-style road manners and appearance you want from the car.
175R14 is a Euro-metric radial size, meaning the tire is 175 millimeters wide, uses radial construction, and fits a 14-inch wheel; in this format, the aspect ratio is not separately stated and is commonly associated with a taller, traditional profile. That makes it a natural fit for the 1974 Nissan 260's original-era sports car character. Within this size, choices include blackwall tires from Michelin and Vredestein across XAS, Sprint Plus, and Sprint Classic lines. The right selection depends on the wheel setup, intended driving use, and whether the goal leans more toward restoration-minded appearance or regular road use.
Tire fitment is straightforward for the covered 1974 Nissan 260 sub-models because the same primary size is shared. Checking the exact sub-model still helps confirm that the car remains on its expected wheel and tire setup before comparing specific tire choices.

Tire Size & Fitment
What tire size fits a 1974 Nissan 260?
The 1974 Nissan 260 uses a 175R14 radial tire. That same primary size also applies to the 1974 Nissan 260 Z, which keeps fitment simple compared with vehicles that split tire sizes by trim or package.
Using the correct size is only the starting point. It still makes sense to confirm that the car retains 14-inch wheels, that wheel width falls within the tire's approved range, and that no past wheel or suspension changes have altered clearance before choosing among available 175R14 tires.
What size rim does a 1974 Nissan 260 use?
The 1974 Nissan 260 uses a 14-inch rim with its 175R14 tire size. The tire size itself ends in 14, which identifies the wheel diameter the tire is built to mount on.
Wheel diameter should be confirmed before buying tires, especially on an older sports car that may have been changed over the years. A 14-inch tire only matches a 14-inch wheel, and wheel width matters too, since available 175R14 products include approved rim-width ranges that should be checked against the wheels currently on the car.
What does 175R14 mean on a 1974 Nissan 260?
On a 1974 Nissan 260, 175R14 is a Euro-metric radial size. The 175 refers to nominal section width in millimeters, the R indicates radial construction, and the 14 identifies the wheel diameter in inches.
This older metric format does not spell out an aspect ratio in the way a modern size like 195/70R14 would. For the buyer, that means the focus should stay on selecting a proper 175R14 tire, then checking wheel width, vehicle stance, and clearance rather than trying to substitute a modern-looking size by assumption.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1974 Nissan 260?
Start with the correct 175R14 size and radial construction, then compare the available tire series, brand, sidewall treatment, and wheel-compatibility details. For the 1974 Nissan 260, the available choices stay within a blackwall presentation, but they differ by series and some product specifications such as approved rim-width range, weight, and load statement.
The best choice depends on how the car is used and how original-looking the finished stance needs to be. A restoration-minded owner may focus on traditional appearance, while a driver may pay closer attention to wheel-width compatibility and the specific character of the Michelin or Vredestein offerings.
What sidewall styles are available for 1974 Nissan 260 tires?
The available 175R14 tires for the 1974 Nissan 260 are offered in blackwall form. That keeps the appearance understated and in line with the clean, sporting look many owners want on an early Z-car.
Since sidewall treatment is not the main point of variation here, the selection process shifts to tire series, brand, and wheel fit details. Blackwall tires can still look quite different once mounted, so it is worth considering tread presentation, overall stance, and how the tire complements the car's restoration style or driver-oriented setup.
What brands offer tires for the 1974 Nissan 260?
Michelin and Vredestein both offer tires in the 175R14 fitment used by the 1974 Nissan 260. The available product lines include Michelin XAS along with Vredestein Sprint Plus and Vredestein Sprint Classic.
Brand choice should be treated as part of a broader fitment decision rather than a shortcut. Compare the specific series offered in 175R14, check the approved wheel-width range where it is stated, and think about whether the car is being finished for period-style presentation, weekend driving, or more regular road use.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Nissan 260?
A period-style 1974 Nissan 260 starts with the correct 175R14 radial size on a 14-inch wheel. From there, the most relevant choices are among the available blackwall radial tires, including Michelin XAS and Vredestein Sprint series options, all of which keep the car within its proper-era sizing format.
Appearance goals should be balanced with the actual wheel setup and how the car will be driven. For owners pursuing a highly exact restoration, brand and presentation details are worth cross-checking against marque references, period photography, or other vehicle-specific historical sources before making a final tire choice.
Does correct tire fitment matter for a 1974 Nissan 260 restoration?
Correct tire fitment matters because the 1974 Nissan 260's proportions, stance, and steering feel are all influenced by tire size and construction. Staying with the proper 175R14 radial format helps preserve the visual balance and intended wheel-to-tire relationship better than an arbitrary substitute size.
Restoration accuracy is not only about what mounts on the wheel. The car should also be checked for original-style wheel diameter, appropriate wheel width, and any suspension changes that could alter the way the tire sits in the wheel opening, since even a good-looking tire choice can appear wrong on a modified setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Nissan 260?
Yes. A 1974 Nissan 260 may still call for a 175R14 tire, but aftermarket wheels, different wheel widths, suspension lowering, spring changes, or body alterations can all change how that size fits in practice.
That is why the car should be checked as it sits today, not just as it left the factory decades ago. Wheel diameter and width, steering travel, and clearance at the fenders and suspension points are all worth confirming before mounting new tires, especially if the car has been restored, modified, or converted for a different stance.
What should I inspect before driving a 1974 Nissan 260 on new tires?
Before road use, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the new 175R14 tires are seated properly and inflated correctly. It also helps to check suspension bushings, alignment condition, and any signs of rubbing at full steering lock.
A collector-era sports car can hide issues that only appear once it is back on the road. Look over the older spare, verify lug hardware condition, and watch for vibration, pulling, or unusual wear during the first miles so small setup problems can be corrected before they affect the new tires.
How should 175R14 tires on a collector 1974 Nissan 260 be maintained?
175R14 tires on a collector 1974 Nissan 260 should be checked regularly for pressure, uneven wear, cracking, bulges, cuts, and signs of air loss. Cars that spend long periods parked deserve extra attention because tire condition can decline with age even when tread mileage remains low.
Storage habits matter almost as much as miles driven. Keeping the car away from prolonged sunlight, moisture, heat, and ozone sources helps preserve the tires, and occasional movement can reduce flat-spotting. A quick inspection before each outing is a smart routine for any vintage Z that is driven intermittently.
