The 1981 Ferrari 308 GTBi sits at an important point in the 308 story, carrying the familiar Pininfarina-shaped wedge profile into the fuel-injected era while preserving the balanced, road-focused character that made the model so memorable. For owners, tire choice matters because the car’s stance, steering feel, and visual presentation are closely tied to its original-size footprint. The 1981 Ferrari 308 GTBi uses a 205/70R14 radial tire on a 14-inch rim. Within that size, choices include blackwall, narrow whitewall, redline, dual-redline, and raised white letter treatments across several classic tire series. The real task is matching the tire to the car’s intended look, wheel setup, and road use.
Which Tire Size Is Right for The 1981 Ferrari 308 GTBi
The 1981 Ferrari 308 GTBi uses one primary tire size: 205/70R14. It is a radial fitment on a 14-inch rim, and the same size applies to the Base sub-model, so the main decision is not between multiple primary sizes but between available tire series, sidewall appearance, and the type of road use or restoration presentation you want from the car.
205/70R14 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1981 Ferrari 308 GTBi, this size keeps the car in its intended radial fitment rather than requiring a bias-ply-versus-radial decision. Available choices in this size include Michelin, BFGoodrich, and Maxxis, with sidewall treatments such as blackwall, narrow whitewall, redline, dual-redline, and raised white letter across series like Michelin XWX, Silvertown Radial, Radial T/A, and Classic Whitewall MA-1. That makes this size straightforward in fitment but meaningful in appearance and product character.
Fitment is straightforward for the covered 1981 Ferrari 308 GTBi sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the car remains on its expected 14-inch wheel setup before comparing available tire styles.

1981 Ferrari 308 GTBi Base
The 1981 Ferrari 308 GTBi Base uses the same 205/70R14 radial tire size as the core model. That keeps selection focused on sidewall style, brand, and tire series rather than sorting through different primary 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 1981 Ferrari 308 GTBi?
The 1981 Ferrari 308 GTBi uses a 205/70R14 radial tire. That is the primary size for this model year and it applies to the Base sub-model as well, so there is no split between multiple factory-size fitments within the covered configuration.
That makes tire selection more about choosing the right version of 205/70R14 than sorting through different sizes. Before replacing tires, confirm that the car still has 14-inch wheels and has not been changed to an aftermarket wheel package or altered suspension setup that could affect clearance and overall fitment.
What size rim does a 1981 Ferrari 308 GTBi use?
The 1981 Ferrari 308 GTBi uses a 14-inch rim with its primary 205/70R14 tire size. Product offerings in this size support that same 14-inch diameter, so the key wheel confirmation is diameter first, then the actual wheel width on the car.
Rim width still matters because available 205/70R14 tires carry different approved width ranges, including 5.00 to 7.00 inches and 5.50 to 7.50 inches. Matching the tire to the wheel already on the car helps avoid mounting a correct-diameter tire on a wheel that is outside the intended width range.
Does the 1981 Ferrari 308 GTBi Base use the same tire size?
Yes. The 1981 Ferrari 308 GTBi Base uses the same 205/70R14 radial tire size as the core 1981 Ferrari 308 GTBi fitment. There is no separate primary size to sort out within the covered sub-model listing.
That consistency simplifies the search, but it still helps to verify the actual wheel and tire setup on the individual car. Collector cars are often changed over time, and a wheel swap, different offset, or nonstandard tire size can leave the car wearing something other than the original-size radial fitment.
Choosing the Right Tire
What should I consider when choosing a 205/70R14 tire for a 1981 Ferrari 308 GTBi?
Start with the correct size and construction: 205/70R14 radial on a 14-inch rim. From there, compare the tire’s sidewall style, tire series, brand, and approved rim-width range so the tire matches both the look of the car and the wheel actually fitted to it.
A blackwall Michelin XWX gives a very different visual impression than a redline, dual-redline, narrow whitewall, or raised white letter option in the same size. It also helps to compare practical details such as load figures where stated and make sure the chosen tire suits the way the car will actually be driven.
What sidewall styles are available for 1981 Ferrari 308 GTBi tires?
The 1981 Ferrari 308 GTBi has several sidewall styles available in 205/70R14, including blackwall, narrow whitewall, redline, dual-redline, and raised white letter. Those options all stay within the same primary tire size while changing the car’s visual character quite a bit.
Choosing among them depends on whether the goal is a restrained European-looking presentation, a more restoration-oriented period style, or a sportier custom look. Sidewall style does not change the need to match the tire to the correct 14-inch wheel diameter and an approved wheel-width range.
What brands offer tires for the 1981 Ferrari 308 GTBi?
Available 205/70R14 tires for the 1981 Ferrari 308 GTBi come from Michelin, BFGoodrich, and Maxxis. Those brands appear across different series and sidewall treatments, so the brand choice also tends to shape the tire’s appearance and character rather than just its name on the sidewall.
A helpful way to compare them is to look at the combination of brand, series, sidewall treatment, and wheel-width compatibility instead of focusing on one factor alone. That approach is especially useful on a car like the 308 GTBi, where appearance and fitment both play a big role in the final decision.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Ferrari 308 GTBi?
A period-style approach for a 1981 Ferrari 308 GTBi starts with the correct 205/70R14 radial size and then focuses on the visual character of the tire. In this size, choices include blackwall, redline, dual-redline, narrow whitewall, and raised white letter treatments across several classic-oriented tire series.
The right choice depends on whether the car is being presented with a restrained European flavor or a more personalized period look. When exact originality matters, the safest approach is to compare the tire style against marque references, period photos, and restoration documentation before making a final selection.
How does tire construction affect the appearance of a restored 1981 Ferrari 308 GTBi?
On the 1981 Ferrari 308 GTBi, construction is already straightforward because the car’s primary fitment is radial. That means the visual difference is driven less by a bias-ply-versus-radial decision and more by sidewall treatment, tread presentation, and the overall character of the tire series chosen.
A blackwall radial can keep the look understated, while redline, dual-redline, narrow whitewall, or raised white letter designs shift the car toward a stronger period-style statement. Keeping the correct 205/70R14 size and proper wheel compatibility intact helps preserve the car’s proportions while refining its finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Ferrari 308 GTBi?
Yes. Even though the primary fitment is a straightforward 205/70R14 radial on a 14-inch rim, modifications can change whether that size still works as expected on an individual 1981 Ferrari 308 GTBi. Wheel swaps, altered offsets, suspension changes, or body modifications can all affect clearance.
A car that has been lowered or fitted with aftermarket wheels should be checked at full steering lock and through suspension travel before settling on a tire. Confirming actual wheel width is also important, since available 205/70R14 products do not all share the same approved rim-width range.
What should I inspect before driving a 1981 Ferrari 308 GTBi on new tires?
Before road use, inspect the wheel condition, valve stems, lug hardware, and overall tire seating, then confirm cold inflation pressure according to the vehicle’s needs and the tire’s condition. It is also smart to check for any rubbing at the front or rear once the new 205/70R14 tires are mounted.
Collector cars often sit for long periods, so a broader inspection matters too. Look over suspension bushings, steering components, brake operation, and any signs of fluid leakage that could affect safe road use, then recheck tire pressure and wheel fastener tightness after the first short drive.
How should 205/70R14 tires on a collector 1981 Ferrari 308 GTBi be maintained?
Maintain 205/70R14 tires on a collector 1981 Ferrari 308 GTBi by checking pressure regularly, watching for uneven wear, and inspecting the sidewalls and tread for cracking, bulges, cuts, or repeated air loss. Cars that see limited mileage still need routine tire attention because age and storage conditions matter.
Good storage habits help preserve the tires between drives. Keep the car away from prolonged sunlight, moisture, and ozone sources, move it occasionally to avoid long-term flat spotting, and inspect the tires before each outing rather than assuming low mileage means they are still road-ready.
