The 1983 Lamborghini Countach belongs to the era when supercar design became sharper, wider, and far more theatrical, and few shapes define that moment more clearly. Its wedge profile and staggered stance make tire fitment a central part of the car’s look as well as its road manners. The 1983 Lamborghini Countach uses two primary radial sizes on 15-inch wheels: 205/50R15 in front and 345/35R15 in the rear. That means the decision is less about choosing between alternate factory-type sizes and more about preserving the Countach’s intended front-to-rear balance, wheel compatibility, and unmistakable visual proportion.
Which Tire Size Is Right for The 1983 Lamborghini Countach
The 1983 Lamborghini Countach uses two primary tire sizes, and they are position-specific rather than interchangeable. Both are radial tires for 15-inch wheels, with 205/50R15 used at the front and 345/35R15 used at the rear. The first step is confirming which end of the car you are fitting, because the Countach’s staggered setup is fundamental to both appearance and fitment.
205/50R15 is a metric radial size in which 205 identifies nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1983 Lamborghini Countach, this is the front tire size and it plays an important role in steering feel, clearance, and the car’s low-slung nose profile. Its comparatively short sidewall is part of the Countach’s distinctly modern-for-its-time tire presentation. Front tire selection should center on maintaining the proper front fitment rather than trying to match the rear size visually.
345/35R15 is a metric radial size with a very wide 345-millimeter nominal section width, a 35-series profile, radial construction, and a 15-inch wheel diameter. On the 1983 Lamborghini Countach, this is the rear tire size and it defines much of the car’s dramatic stance and broad rear footprint. The size is unusually wide by most passenger-car standards, so rear wheel compatibility and body clearance matter immediately. Choosing this size correctly helps preserve the Countach’s intended staggered setup instead of treating the car like a same-size four-corner application.
Fitment on the 1983 Lamborghini Countach is straightforward once the tire position is identified, because the front and rear are treated as separate applications. Checking the exact sub-model naming matters here because the Countach uses a staggered radial setup rather than one shared size at all four corners.

1983 Lamborghini Countach LP500S Front
The 1983 Lamborghini Countach LP500S Front uses a dedicated 205/50R15 radial tire size. Front tire selection should focus on preserving the correct steering-end fitment and confirming that the wheel setup still matches the car’s intended 15-inch front application.
The 1983 Lamborghini Countach LP500S Rear uses a dedicated 345/35R15 radial tire size. Rear tire selection needs to respect the Countach’s wide staggered stance, making wheel width and rear clearance more important than simply matching a metric size code.
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.
Frequently Asked Questions
Owners usually need to confirm the Countach’s staggered front and rear sizing first, then work through wheel fitment, appearance, and road-use checks. The questions below focus on exact tire size, 15-inch rim fitment, selection priorities, and what to inspect before driving.
Tire Size & Fitment
What tire size fits a 1983 Lamborghini Countach?
The 1983 Lamborghini Countach uses a staggered radial tire setup with 205/50R15 in front and 345/35R15 in the rear. Those are two separate primary fitments, not alternate sizes for the same wheel position, and both are built around 15-inch rims.
That means the key question is whether the tire is for the front or rear of the car. A Countach with aftermarket wheels, prior modifications, or replacement bodywork should have its actual wheel dimensions and clearances checked before tire selection, because this car’s unusually wide rear fitment leaves less room for assumptions.
What size rim does a 1983 Lamborghini Countach use?
The 1983 Lamborghini Countach uses 15-inch rims with both of its primary tire sizes. The front 205/50R15 and rear 345/35R15 both share the same rim diameter, even though the tires differ dramatically in width and profile.
Rim diameter is only the first checkpoint on a Countach. The front and rear tire sizes are position-specific, so wheel width and overall wheel setup still need to match the intended tire before mounting, especially at the rear where the tire is exceptionally wide compared with conventional passenger-car fitments.
Why does the 1983 Lamborghini Countach have more than one tire size?
The 1983 Lamborghini Countach has more than one tire size because it uses a staggered setup. The front takes 205/50R15, while the rear uses 345/35R15, giving the car distinctly different tire dimensions at each end.
That layout is part of the Countach’s design and should be treated as a front-versus-rear fitment requirement rather than a menu of interchangeable sizes. Anyone replacing tires should verify which axle is being serviced and confirm the wheel arrangement already on the car, especially if it has seen wheel changes during restoration or earlier ownership.
Choosing the Right Tire
What should I consider when choosing a 205/50R15 and 345/35R15 tire for a 1983 Lamborghini Countach?
Start with the Countach’s exact staggered sizing: 205/50R15 for the front and 345/35R15 for the rear, both in radial construction on 15-inch rims. The main selection factors are using the correct axle-specific size, confirming wheel compatibility, and preserving the car’s intended front-to-rear visual and dimensional relationship.
Collector use matters as much as pure fitment on a Countach. A car aimed at display may emphasize authentic-looking proportion, while a road-driven example needs equal attention to tire condition, age, and clearance under steering and suspension movement, particularly if ride height, wheel width, or alignment settings have changed over time.
How do I choose between the available 1983 Lamborghini Countach tires?
Choosing tires for a 1983 Lamborghini Countach begins with separating the front and rear applications rather than comparing unrelated sizes. The front 205/50R15 and rear 345/35R15 serve different roles, so the right choice depends first on position, then on the wheel setup and the kind of use the car will see.
A restoration-oriented owner may place more emphasis on preserving the Countach’s signature stance, while a regularly driven car may call for extra scrutiny of tire age and current condition. It also helps to inspect the car for non-original wheels or suspension changes, since even small setup differences can matter on a low, wide exotic.
What rim-fitment details should I compare when choosing 1983 Lamborghini Countach tires?
The first rim-fitment detail is diameter, and the 1983 Lamborghini Countach uses 15-inch rims front and rear. After that, the important comparison is whether each wheel is appropriate for its intended axle, because the front 205/50R15 and rear 345/35R15 are dramatically different in width and should not be treated as interchangeable.
Wheel width and physical clearance become especially important at the rear of the car. Any Countach that has aftermarket wheels, changed offset, altered suspension height, or bodywork variations should be measured carefully before mounting tires, since the correct size code alone does not confirm that the complete wheel-and-tire package is suitable.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Lamborghini Countach?
A period-style 1983 Lamborghini Countach tire choice starts with keeping the correct staggered radial sizing in place: 205/50R15 at the front and 345/35R15 at the rear. Because the Countach’s visual identity depends heavily on its low front profile and wide rear stance, preserving that size relationship is the foundation of an authentic-looking presentation.
Beyond the size itself, restoration-minded owners should compare the overall look each tire creates on the car rather than focusing only on basic compatibility. When exact historical presentation matters, marque references and vehicle-specific documentation are worth consulting so the finished tire choice suits the Countach’s era and intended appearance.
Does correct tire fitment matter for a 1983 Lamborghini Countach restoration?
Correct tire fitment matters greatly on a 1983 Lamborghini Countach restoration because the car’s stance is inseparable from its design. The front 205/50R15 and rear 345/35R15 combination is not just a technical detail; it shapes the car’s side profile, wheel opening relationship, and the visual balance that makes a Countach look right.
A restoration can lose much of its character if the front-to-rear proportion changes, even when the tires appear close at a glance. That is why wheel diameter, tire width, and axle position should all be verified carefully, particularly on cars that may have received replacement wheels or suspension changes years before restoration work began.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Lamborghini Countach?
Modifications can absolutely affect tire fitment on a 1983 Lamborghini Countach. Even though the correct primary sizes are 205/50R15 front and 345/35R15 rear, wheel changes, altered ride height, suspension work, alignment changes, or body modifications can change how much space is available around the tire.
That matters more on a Countach than on many ordinary cars because its rear fitment is exceptionally wide and the body is very low. A modified example should have front steering clearance and rear body and suspension clearance checked carefully before road use, rather than assuming that the original size code settles the whole fitment question.
What should I inspect before driving a 1983 Lamborghini Countach on new tires?
Before driving a 1983 Lamborghini Countach on new tires, inspect the wheels for the correct 15-inch diameter and suitable condition, then confirm that the front 205/50R15 and rear 345/35R15 tires are mounted in the proper positions. Tire pressure, valve condition, and visible clearance at both ends of the car should also be checked.
A slow first road test is wise on a collector car with fresh tires. Pay attention to any rubbing during steering input, suspension compression, or reversing, and recheck pressures after the first drive, since a low, staggered exotic can reveal fitment issues quickly if wheel specs or suspension settings are no longer as intended.
How should tires on a collector 1983 Lamborghini Countach be maintained?
Tires on a collector 1983 Lamborghini Countach should be maintained with regular pressure checks, visual inspections, and attention to age as well as tread. A car that sees limited mileage can still develop sidewall cracking, flat spotting, air loss, or general deterioration simply from time, storage conditions, and infrequent use.
Storage habits matter on a Countach because many examples spend long periods parked. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and occasional inspection of both front and rear clearances is useful too, especially after any wheel, suspension, or alignment work.
