The 1975 Ferrari 308 arrived at a moment when Ferrari’s mid-engine road cars were becoming more usable on real roads without losing their exotic character. In 1975 form, the 308 GT4 paired sharp Bertone styling with the kind of balanced chassis response that makes tire choice especially important today. This Ferrari uses a 205/70R14 radial on a 14-inch rim, so the decision is less about multiple factory fitments and more about selecting the right radial within that size. Available choices include blackwall, narrow whitewall, redline, dual-redline, and raised white letter presentations, giving owners room to balance road use, appearance, and restoration priorities.
Which Tire Size Is Right for The 1975 Ferrari 308
The 1975 Ferrari 308 uses one primary tire size: 205/70R14, a radial fitment on a 14-inch rim. Because the covered sub-model shares that same size, the main choice is not between different fitments, but between tire character, sidewall style, brand, and whether the car is being kept close to a period-style presentation or set up for regular road use.
In 205/70R14, the 205 identifies the tire's nominal section width in millimeters, the 70 is the aspect ratio, the R indicates radial construction, and the 14 is the wheel diameter in inches. That radial format suits the 1975 Ferrari 308's era of increasingly modern handling and highway use. Within this size, there is meaningful variety, including Michelin XWX blackwall, BFGoodrich Radial T/A raised white letter, BFGoodrich Silvertown Radial redline and dual-redline options, and a Maxxis narrow whitewall. Choosing within 205/70R14 comes down to the look you want, the wheel-width range involved, and how closely the tire's appearance matches your plans for the car.
Sub-model fitment is straightforward for the covered 1975 Ferrari 308 application. The listed sub-model uses the same 205/70R14 radial size, so selection centers on tire style and wheel compatibility rather than sorting through multiple primary sizes.

Tire Size & Fitment
What tire size fits a 1975 Ferrari 308?
The 1975 Ferrari 308 uses a 205/70R14 radial tire. For the covered application, that is the primary fitment size, and the listed 1975 Ferrari 308 GT4 uses the same sizing rather than a separate alternate factory-size fitment within this page.
That makes the buying decision much more about choosing the right tire within 205/70R14 than trying to sort through multiple primary sizes. It is still important to confirm that the car remains on 14-inch wheels and has not been changed to aftermarket wheels or a different tire setup over the years.
What size rim does a 1975 Ferrari 308 use?
The primary tire fitment for the 1975 Ferrari 308 is built around a 14-inch rim, as reflected by the 205/70R14 size. Available tires in this size are also matched to 14-inch wheel diameter, with product rim-width ranges that generally fall between 5.00 and 7.50 inches depending on the tire.
Wheel diameter is the first thing to confirm before ordering tires, especially on a collector car that may have changed hands several times. After diameter is verified, compare the wheel's actual width to the tire's approved range so the new tire's shape, clearance, and seating are appropriate for the car's current setup.
Does the 1975 Ferrari 308 GT4 use the same tire size?
Yes. The 1975 Ferrari 308 GT4 uses the same 205/70R14 radial tire size as the covered 1975 Ferrari 308 application on this page. There is no separate primary size shown here for the GT4 that would require a different wheel diameter or a different basic sizing format.
That consistency simplifies replacement, but it does not remove the need to inspect the car itself. A GT4 that has been modified with different wheels, altered ride height, or suspension changes should still be measured and checked before selecting among available 205/70R14 products.
Choosing the Right Tire
What should I consider when choosing a 205/70R14 tire for a 1975 Ferrari 308?
Start with the confirmed 205/70R14 size, then compare tire construction, sidewall appearance, brand, and wheel-width compatibility. For the 1975 Ferrari 308, available choices include blackwall, narrow whitewall, redline, dual-redline, and raised white letter radials from Maxxis, BFGoodrich, and Michelin.
The right choice depends on how the car is used and presented. A more understated road-car look may point toward a blackwall tire, while redline or dual-redline may better suit a period-style presentation. Wheel width matters too, since some 205/70R14 products are approved from 5.00 to 7.00 inches and others from 5.50 to 7.50 inches.
What sidewall styles are available for 1975 Ferrari 308 tires?
The 1975 Ferrari 308's 205/70R14 fitment is available with several distinct sidewall styles. Choices include blackwall, narrow whitewall, redline, dual-redline, and RWL, which is the raised white letter style seen on some BFGoodrich Radial T/A tires.
That range gives the car very different visual personalities even when the size stays the same. A blackwall keeps the presentation restrained and European in character, while redline or dual-redline adds more vintage visual emphasis. Sidewall style should be chosen alongside brand, tire series, and wheel compatibility rather than as an appearance-only decision.
What brands offer tires for the 1975 Ferrari 308?
Tires for the 1975 Ferrari 308 in 205/70R14 are available from Maxxis, BFGoodrich, and Michelin. Those brands cover several different tire series, including Classic Whitewall MA-1, Radial T/A, Silvertown Radial, and Michelin XWX, all within the same basic fitment size.
Brand choice should be considered together with the tire's series and sidewall treatment, since those details shape the look and intended character of the car. It also helps to compare each tire's approved rim-width range before choosing, because the available 205/70R14 options do not all share the exact same wheel-width specification.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Ferrari 308?
A period-style 1975 Ferrari 308 still begins with the correct primary size, 205/70R14. From there, the decision shifts to which radial best matches the look you want, with blackwall, redline, dual-redline, narrow whitewall, and raised white letter options all available in that same basic fitment.
For a restoration-minded owner, appearance should be weighed alongside wheel-width compatibility and intended use. If exact originality matters, it is wise to compare the car against marque references, period photographs, or ownership history before settling on a sidewall style, since period-style and factory-delivered appearance are not always the same thing.
How does tire construction affect the appearance of a restored 1975 Ferrari 308?
On this application, construction choice is straightforward because the primary fitment is already a radial: 205/70R14. That means the visual differences for a restored 1975 Ferrari 308 come less from switching between bias-ply and radial construction, and more from the tire series and sidewall treatment chosen within the radial category.
A blackwall Michelin XWX creates a very different impression from a redline or raised white letter tire even though all share the same basic size. Owners restoring for judged presentation or marque-specific authenticity should look beyond size alone and consider how tread style, lettering, and sidewall accenting influence the finished stance of the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Ferrari 308?
Yes. Even though the primary size for a 1975 Ferrari 308 is 205/70R14, modifications can change what actually works on the car. Aftermarket wheels, altered wheel widths, suspension changes, brake conversions, or ride-height adjustments can all affect clearance and how a tire sits on the rim.
A car that still carries its original-style wheel and suspension layout is much easier to match to the available 205/70R14 options. Once the setup has been changed, confirm wheel diameter first, then check wheel width and inspect turning and fender clearance before choosing among the available radial tires.
What should I inspect before driving a 1975 Ferrari 308 on new tires?
Before road use, inspect the wheels for correct diameter and condition, make sure the tires are mounted in the proper 205/70R14 size, and verify inflation pressure appropriate to the tire and vehicle setup. It also helps to look over valve stems, balance, tread seating, and any signs of rubbing at full steering lock.
A collector Ferrari deserves a broader check before its first serious drive. Examine suspension bushings, shocks, alignment condition, and brake operation, then recheck the tires after a short run for air loss or contact marks. That extra inspection is especially worthwhile if the car has spent long periods stored or lightly used.
How should 205/70R14 tires on a collector 1975 Ferrari 308 be maintained?
Maintain 205/70R14 tires on a collector 1975 Ferrari 308 by checking pressure regularly, watching for sidewall cracking, cuts, bulges, uneven tread wear, and any sign of slow air loss. Low-mileage collector cars can age their tires before they wear them out, so condition matters as much as remaining tread depth.
Storage habits also influence tire life. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources, and inspect the tires before each drive if the Ferrari is used only occasionally. Any vibration, pulling, or visible aging should be addressed before extended road use rather than after the next outing.
