The 1977 Ferrari 308 sits squarely in the era when mid-engine Italian sports cars became a defining part of exotic-car culture, blending compact proportions, sharp styling, and a road-going balance that still appeals to collectors today. Tire choice matters on a car like this because steering response, stance, and period presentation are all part of the ownership experience. The 1977 Ferrari 308 uses a 205/70R14 radial tire on a 14-inch wheel, and both the 308 GT4 and 308 GTB/S share that fitment. Available choices include blackwall, narrow whitewall, redline, dual-redline, and raised white letter styles, so the decision often comes down to appearance, driving use, and wheel compatibility.
Which Tire Size Is Right for The 1977 Ferrari 308
The 1977 Ferrari 308 uses one primary tire size: 205/70R14, a radial tire built for a 14-inch rim. That fitment carries across the covered 308 sub-models, so the main decision is not which size fits, but which tire best matches the car’s intended look, driving style, and wheel setup.
A 205/70R14 tire uses a 205-millimeter section width, a 70-series profile, radial construction, and a 14-inch rim diameter. On the 1977 Ferrari 308, that means a modern metric radial format rather than an older numeric or alphanumeric bias-ply size. Within this size, available choices include Michelin, BFGoodrich, and Maxxis products, with sidewall treatments ranging from blackwall and narrow whitewall to redline, dual-redline, and raised white letter. Selecting among them usually comes down to whether the goal is a more European touring look, a restoration-oriented presentation, or a sportier visual style.
Tire fitment is straightforward across the covered 1977 Ferrari 308 sub-models because both use the same 205/70R14 radial size. Checking the exact sub-model still helps confirm that the car remains on the expected 14-inch wheel setup before choosing among available tire styles.

1977 Ferrari 308 GT4
The 1977 Ferrari 308 GT4 uses the same 205/70R14 radial tire size as the other covered 308 configuration. That keeps size selection simple and shifts the focus toward sidewall appearance, brand preference, and confirming that the wheel width still matches the tire being considered.
The 1977 Ferrari 308 GTB/S also uses a 205/70R14 radial tire on a 14-inch rim. With the primary fitment shared, the key choice becomes whether the car calls for a traditional blackwall look, a more distinctive redline-style presentation, or another period-inspired sidewall treatment.
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 1977 Ferrari 308?
The 1977 Ferrari 308 uses a 205/70R14 radial tire. That same primary size applies to both the 1977 Ferrari 308 GT4 and the 1977 Ferrari 308 GTB/S, keeping fitment straightforward across the covered sub-models.
Even with one primary size, it is still worth confirming that the car remains on 14-inch wheels and has not been changed to a different wheel package over the years. Once the size is verified, the next decision is usually brand, sidewall appearance, and matching the tire’s approved rim-width range to the actual wheel on the car.
What size rim does a 1977 Ferrari 308 use?
The primary tire fitment for the 1977 Ferrari 308 is built around a 14-inch rim diameter. The 205/70R14 size itself confirms that wheel diameter, and the available tire choices in this fitment are all intended for 14-inch wheels.
Rim diameter is only part of the check, because wheel width also matters when comparing available tires. Some 205/70R14 products are suited to 5.00 to 7.00-inch rims, while others call for 5.50 to 7.50 inches, so measuring the actual wheel can help narrow the best options before mounting new tires.
Do all 1977 Ferrari 308 sub-models use the same tire size?
Yes. The covered 1977 Ferrari 308 sub-models share the same primary tire size, 205/70R14 radial. That applies to both the 308 GT4 and the 308 GTB/S, so there is no split fitment between those two versions on this page.
Shared sizing makes replacement simpler, but it does not remove the need to inspect the car itself. A long-owned collector Ferrari may have aftermarket wheels, replacement rims, or suspension changes, and those details can affect how comfortably a given 205/70R14 tire works within the available wheel-width and clearance envelope.
Choosing the Right Tire
What should I consider when choosing a 205/70R14 tire for a 1977 Ferrari 308?
Start with the basics: correct 205/70R14 sizing, radial construction, and a 14-inch wheel. After that, compare the tire’s approved rim-width range, sidewall style, and overall character, since the available choices for the 1977 Ferrari 308 span several visual presentations and series.
A Michelin XWX blackwall gives a different look from a BFGoodrich redline, dual-redline, or raised white letter tire, and a narrow whitewall creates another distinct appearance again. The right choice depends on whether the car is being presented as a restoration-oriented road car, a period-style driver, or a collector vehicle with a more personalized visual theme.
What sidewall styles are available for 1977 Ferrari 308 tires?
The 1977 Ferrari 308 has 205/70R14 tire choices in several sidewall styles, including blackwall, narrow whitewall, redline, dual-redline, and RWL, or raised white letter. Those options create very different visual effects even though the core size remains the same.
Sidewall style is often one of the biggest appearance decisions on a collector car because it changes the car’s stance and period impression without altering wheel size. Matching the sidewall treatment to the car’s intended look is usually more important than following trends, especially on a Ferrari where subtle visual details can strongly affect the finished presentation.
What brands offer tires for the 1977 Ferrari 308?
Available 205/70R14 tires for the 1977 Ferrari 308 include products from Michelin, BFGoodrich, and Maxxis. Those brands cover several different tire series, including Michelin XWX, BFGoodrich Radial T/A, BFGoodrich Silvertown Radial, and Maxxis Classic Whitewall MA-1.
Brand choice is best treated as part of a larger comparison rather than the only decision. Looking at sidewall treatment, rim-width compatibility, and the overall style of each series will usually tell you more about which tire belongs on your particular 308 than the name on the sidewall alone.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Ferrari 308?
A period-style 1977 Ferrari 308 usually starts with staying in the correct 205/70R14 radial size on the proper 14-inch wheel. From there, a blackwall Michelin XWX offers a very traditional European presentation, while redline, dual-redline, narrow whitewall, and raised white letter options move the look in different directions.
The best visual match depends on the car’s restoration goal and how closely the finished appearance is meant to follow a particular era or delivery style. When exact originality matters, it is wise to compare the car against marque-specific references, period photos, and restoration documentation before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 1977 Ferrari 308?
On a restored 1977 Ferrari 308, construction is less of a visual dividing line than it would be on an earlier bias-ply-era car because the primary fitment is already radial. Appearance is shaped more by the sidewall treatment and tire series than by choosing between bias-ply and radial construction.
That still leaves meaningful visual differences. A blackwall can preserve a restrained sports-car look, while redline, dual-redline, narrow whitewall, or raised white letter tires create a more assertive or personalized presentation. Keeping the proper 205/70R14 size is the key step, because size itself has a major effect on stance and overall visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Ferrari 308?
Yes. Even though the primary fitment for a 1977 Ferrari 308 is 205/70R14 on a 14-inch rim, changes to wheels, suspension height, alignment settings, or body clearance can alter how comfortably that size works on the car. Collector vehicles are often changed over time.
A modified 308 should be checked for actual wheel width, wheel diameter, and clearance at full steering and suspension movement before new tires are selected. Those checks matter just as much as the published tire size, especially when comparing products that share 205/70R14 sizing but have slightly different approved rim-width ranges.
What should I inspect before driving a 1977 Ferrari 308 on new tires?
Inspect the wheels for damage, confirm the wheel size, and make sure the selected 205/70R14 tire matches the wheel’s width range. It is also smart to check alignment condition, valve stems, and whether the suspension and steering components are in healthy shape before putting fresh tires into service.
After installation, keep an eye on inflation pressure, initial air retention, and any signs of rubbing or uneven wear during the first drives. A 1977 Ferrari 308 that has spent long periods parked deserves extra attention, since dormant collector cars can hide age-related issues that only become obvious once the car is back on the road.
How should 205/70R14 tires on a collector 1977 Ferrari 308 be maintained?
Collector-car tires should be maintained with regular pressure checks, visual inspections, and periodic evaluation for age, cracking, cuts, bulges, and irregular wear. On a 1977 Ferrari 308, low annual mileage does not remove the need for inspection, because time and storage conditions matter as much as miles.
Storage practices also play a big role in tire life. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives, and routine checks before road use are especially important if the Ferrari sits for extended periods rather than being driven regularly.
