The 1984 Lamborghini Countach belongs to the era when exotic supercars became sharper, wider, and more visually dramatic, and few cars express that better than this low, wedge-shaped Lamborghini. Its stance is a major part of the experience, which makes tire fitment especially important on a Countach. The 1984 Lamborghini Countach uses staggered radial sizes, with 205/50R15 at the front and 345/35R15 at the rear, both on 15-inch rims. That means the real tire decision centers on preserving the car’s intended front-to-rear balance, confirming wheel fitment, and maintaining the unmistakable wide-rear look that defines this generation.
Which Tire Size Is Right for The 1984 Lamborghini Countach
The 1984 Lamborghini Countach uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. Both are radial tires for 15-inch rims, but the first step is confirming whether you are selecting a front or rear tire, because the Countach’s staggered setup is central to its fitment and appearance.
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 rim diameter in inches. On the 1984 Lamborghini Countach, this is the front tire size and it plays a major role in steering response, clearance, and overall front-end proportion. Because the Countach uses a staggered arrangement, this size should be evaluated as part of the complete front-to-rear setup rather than in isolation. Wheel width, suspension condition, and any previous modifications should be checked before replacement.
345/35R15 is a metric radial size with a very wide 345-millimeter section width, a 35-series profile, radial construction, and a 15-inch rim diameter. On the 1984 Lamborghini Countach, this is the rear tire size and a defining part of the car’s visual stance and road-going setup. Its width makes proper wheel compatibility and rear clearance especially important, particularly on a collector car that may have had wheel or suspension changes over time. This is the size to focus on when preserving the Countach’s dramatic wide-rear presentation.
Fitment on the 1984 Lamborghini Countach is straightforward once the tire position is identified. The covered Countach LP500S front and rear applications use different sizes, so selecting the correct tire depends on matching the tire to the proper end of the car.

1984 Lamborghini Countach LP500S Front
The 1984 Lamborghini Countach LP500S Front uses a 205/50R15 radial tire on a 15-inch rim. For tire selection, the focus should be on preserving the intended front fitment while confirming wheel compatibility, steering clearance, and any changes made to the suspension or ride height.
The 1984 Lamborghini Countach LP500S Rear uses a 345/35R15 radial tire on a 15-inch rim. That makes rear tire selection especially important for maintaining the car’s staggered setup, wide-body visual balance, and the clearance needed around the wheel, suspension, and bodywork.
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
Common 1984 Lamborghini Countach tire questions usually come down to front versus rear sizing, 15-inch wheel fitment, preserving the staggered radial setup, and checking wheel, suspension, and clearance details before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 1984 Lamborghini Countach?
The 1984 Lamborghini Countach uses a staggered tire setup with 205/50R15 at the front and 345/35R15 at the rear. Both are radial tire sizes, and both are designed for 15-inch rims. These are position-specific sizes, so the front and rear are not interchangeable.
That staggered arrangement is a major part of Countach fitment, appearance, and balance. The first step is identifying whether the tire is for the front or rear of the car, then confirming the actual wheel dimensions on the vehicle. Any aftermarket wheel changes, suspension work, or body modifications should be checked before replacing tires.
What size rim does a 1984 Lamborghini Countach use?
The 1984 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 tire widths and profiles are very different between the front and rear positions.
Matching rim diameter is only the starting point on a staggered exotic-car setup. Wheel width and overall wheel configuration still need to suit the specific front or rear tire being installed. On a Countach, it is smart to inspect the wheel itself and verify the current setup on the car before assuming any 15-inch wheel will accept the tire properly.
Why does the 1984 Lamborghini Countach have more than one tire size?
The 1984 Lamborghini Countach has more than one tire size because it uses a staggered setup. The front position takes a 205/50R15 tire, while the rear position uses a much wider 345/35R15 tire. That is not a trim-level difference; it is how the car is configured front to rear.
For tire selection, that means the correct question is not which single size fits the Countach, but which position you are buying for. The front and rear tires serve different fitment roles, so buyers should verify wheel placement, wheel dimensions, and surrounding clearance before replacing one axle set or the entire set.
Choosing the Right Tire
What should I consider when choosing 1984 Lamborghini Countach tires?
Start with the basic Countach fitment: 205/50R15 in front and 345/35R15 in the rear, both in radial construction. Because the car uses a staggered layout, the most important selection point is matching the correct size to the correct end of the vehicle rather than treating the fitment like a uniform four-tire setup.
From there, verify the actual wheels on the car and inspect whether the suspension, ride height, or bodywork has been changed over time. On a collector supercar, even small setup differences can matter. Tire choice should support the Countach’s intended stance, maintain proper front and rear proportions, and leave enough operating clearance around the wheel openings and suspension.
How do I choose between the available 205/50R15 and 345/35R15 tires for a 1984 Lamborghini Countach?
Choosing between the Countach’s tire sizes is really a matter of position, not preference. The 205/50R15 belongs at the front and the 345/35R15 belongs at the rear. Each size fills a different fitment role, so they should be selected as part of the car’s staggered design rather than compared as alternatives to one another.
A good selection process starts by confirming whether you are replacing front tires, rear tires, or the full set. It also helps to inspect the current wheels and compare the existing setup against the intended tire position. That keeps the Countach’s visual balance intact and reduces the chance of ordering a tire that does not suit the car’s current wheel package.
What rim-fitment details matter when choosing tires for a 1984 Lamborghini Countach?
Rim diameter matters first, and the 1984 Lamborghini Countach uses 15-inch rims at both ends. After that, position-specific wheel fitment becomes critical because the front 205/50R15 and rear 345/35R15 are dramatically different in width and profile, even though they share the same nominal rim diameter.
A tire for this car should be evaluated against the actual wheel it will be mounted on, not just the size stamped on the sidewall. The owner should confirm wheel width, inspect for previous wheel changes, and look closely at steering and body clearance. That is especially important on the rear, where the Countach’s extra-wide tire is central to fitment.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Lamborghini Countach?
A period-style approach starts with preserving the Countach’s staggered radial sizing: 205/50R15 in front and 345/35R15 in the rear. Those sizes are a major part of the car’s visual identity, especially the very wide rear tire that gives the 1984 Lamborghini Countach its unmistakable planted stance.
For a restoration-oriented result, keeping the correct front-to-rear relationship matters as much as choosing the right individual sizes. The actual wheels on the car should be checked carefully, especially if the car has changed hands or seen previous cosmetic work. Buyers focused on strict originality may also want to compare their setup with marque-specific historical references.
Does correct tire fitment matter for a 1984 Lamborghini Countach restoration?
Correct tire fitment matters a great deal on a 1984 Lamborghini Countach restoration because the car’s visual character depends heavily on its low nose, staggered proportions, and wide rear footprint. Using the proper front 205/50R15 and rear 345/35R15 sizes helps preserve the stance that defines this generation of Countach.
Fitment also affects how convincingly the finished car presents as a cohesive whole. A restoration-minded owner should look beyond simple rim diameter and verify the actual wheel setup, tire positioning, and surrounding clearance. On a Countach, tires are not just routine service parts; they are an important part of the restored car’s overall presence.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Lamborghini Countach?
Yes, modifications can affect tire fitment on a 1984 Lamborghini Countach, especially because the car uses a very specific staggered radial setup. Changes to wheels, ride height, suspension settings, brake components, or bodywork can alter the space available for the front 205/50R15 and rear 345/35R15 tires.
That means any Countach with aftermarket wheels or suspension work should be checked carefully before replacement tires are chosen. Clearance at full steering lock, wheelhouse spacing, and rear fitment all matter. Even when the tire size itself is correct, the current vehicle setup may differ from an unmodified example and should be verified in person.
What should I inspect before driving a 1984 Lamborghini Countach on new tires?
Before driving a 1984 Lamborghini Countach on new tires, inspect the wheels, valve stems, mounting condition, and inflation pressure, then make sure the front and rear tires are installed in their correct positions. It is also wise to look over suspension components and check that nothing is rubbing or sitting unusually close to the tire.
A short, careful road test is the best next step after installation. Watch for steering interference, vibration, unusual noises, or any sign of contact under load or while turning. On a low-production collector car, it also makes sense to recheck pressure and visible clearance after the first few miles rather than assuming everything has settled correctly.
What should I check before a longer drive in a 1984 Lamborghini Countach?
Before a longer drive in a 1984 Lamborghini Countach, confirm that the front 205/50R15 and rear 345/35R15 tires are in good condition, properly inflated, and free from cracking, bulges, cuts, or unusual wear. A collector car that spends long periods parked deserves extra attention before being asked to cover real road miles.
It also helps to inspect the wheels, look for slow air loss, and make sure the suspension and steering feel stable at low speed before heading farther out. Storage-aged tires can look usable at a glance, so condition matters as much as tread depth. A careful pre-drive inspection is part of responsible Countach ownership.
