By 1989, the Lamborghini Countach had evolved from a 1970s wedge-shaped supercar statement into one of the defining exotic performance cars of its era. The final production years carried the same dramatic stance and wide-body presence that made the Countach such a poster-car fixture, and tire fitment is a major part of that look. The 1989 Lamborghini Countach uses a staggered radial setup with 225/50R15 in front and 345/35R15 in the rear. That makes the real decision less about discovering the size and more about preserving the car’s intended stance, confirming front-versus-rear fitment, and keeping wheel and tire specifications aligned before road use.
Which Tire Size Is Right for The 1989 Lamborghini Countach
The 1989 Lamborghini Countach uses two primary tire sizes, and the key is identifying where each one belongs on the car. Both are radial tires built for 15-inch rims, but this is a staggered front-and-rear fitment rather than an interchangeable setup. Before choosing a tire, confirm whether you are replacing the front or rear pair and make sure the car still has the correct wheel arrangement.
Fit(s): 25th Anniversary Front and 5000 quattrovalvole Front
Construction: Radial|Rim: 15 in
225/50R15 is a metric radial size in which 225 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 1989 Lamborghini Countach, this size serves the front position and helps define the car’s staggered handling and visual balance. Because it is part of a front-specific fitment, the decision is less about substitution and more about preserving the intended wheel location, tire proportions, and compatibility with the existing setup. Front tire replacement should always be checked against the actual wheel dimensions on the car.
Fit(s): 25th Anniversary Rear and 5000 quattrovalvole Rear
Construction: Radial|Rim: 15 in
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 rim diameter. On the 1989 Lamborghini Countach, this is the rear tire size and a major part of the car’s unmistakable wide-track supercar stance. Its role is highly specific, so it should be treated as a rear-position fitment rather than a general Countach tire size. Rear tire selection should focus on maintaining the proper staggered layout and verifying that the wheels and body clearance still match the car’s current configuration.
Sub-model fitment on the 1989 Lamborghini Countach is straightforward in size but still requires attention to position. The covered versions share the same staggered radial arrangement, so the main task is confirming whether the tire is for the front or rear of the car.

1989 Lamborghini Countach 25th Anniversary Front
The 1989 Lamborghini Countach 25th Anniversary Front uses the front portion of the Countach staggered radial setup. Tire selection here centers on keeping the correct front size in place and verifying that the wheel on the car still matches the intended front fitment.
The 1989 Lamborghini Countach 25th Anniversary Rear uses the dedicated rear tire size in the Countach’s staggered layout. That makes rear tire choice especially important for preserving the car’s wide rear presentation and checking wheel and clearance compatibility before replacement.
1989 Lamborghini Countach 5000 quattrovalvole Front
The 1989 Lamborghini Countach 5000 quattrovalvole Front uses the same front radial tire size as the other covered Countach configuration. The practical decision is confirming front position fitment and matching the tire to the car’s actual wheel setup if any changes have been made over time.
The 1989 Lamborghini Countach 5000 quattrovalvole Rear uses the same rear radial tire size found on the other covered Countach configuration. Rear replacement should keep the staggered arrangement intact and be checked carefully against the installed wheel width and available clearance.
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 of a 1989 Lamborghini Countach usually need clarity on staggered tire sizing, 15-inch rim fitment, front-versus-rear placement, and what to inspect before putting a collector-era supercar back on the road.
Tire Size & Fitment
What tire size fits a 1989 Lamborghini Countach?
The 1989 Lamborghini Countach uses a staggered radial tire setup with 225/50R15 in front and 345/35R15 in the rear. Those are both 15-inch radial sizes, but they are not the same tire used at all four corners. The front and rear fitments serve different positions on the car.
That means the first step is confirming whether the tire being replaced is on the front or rear axle. A Countach with changed wheels, suspension work, or long-term storage history should also have its actual wheel dimensions and available clearance checked before a replacement tire is chosen.
What size rim does a 1989 Lamborghini Countach use?
The 1989 Lamborghini Countach uses 15-inch rims with both of its primary tire sizes. The 225/50R15 front tire and 345/35R15 rear tire are each built around a 15-inch rim diameter, even though the tires themselves are very different in width and profile.
Rim diameter is only one part of the fitment picture on a staggered exotic like the Countach. Wheel width and the front-versus-rear wheel arrangement still matter, so a 15-inch wheel should not be assumed correct unless its full specifications match the position where the tire will be installed.
Do all 1989 Lamborghini Countach sub-models use the same tire size?
The covered 1989 Lamborghini Countach sub-models share the same staggered tire sizing pattern. Both the 25th Anniversary and 5000 quattrovalvole use 225/50R15 at the front and 345/35R15 at the rear, so the fitment is consistent across those versions.
Even with that consistency, tire selection still depends on position rather than sub-model name alone. Front and rear tires should be matched to the correct axle, and any Countach that no longer has its original-style wheel setup deserves a fresh check of wheel dimensions and surrounding clearance.
Choosing the Right Tire
What should I consider when choosing a 225/50R15 or 345/35R15 tire for a 1989 Lamborghini Countach?
Start with the correct axle position, because the 1989 Lamborghini Countach uses 225/50R15 in front and 345/35R15 in the rear. Both are radial 15-inch sizes, but they are not interchangeable. The front tire supports the narrow leading edge of the staggered setup, while the rear carries the much wider footprint.
After size and position are confirmed, attention should turn to wheel compatibility, overall condition of the wheels, and the car’s present configuration. A Countach that has seen wheel changes, suspension work, or body adjustments should be inspected carefully so the replacement tire suits the way the car actually sits today.
How do I choose between the available 1989 Lamborghini Countach tires if the sizes are already known?
Once the size is established, the real choice is making sure the tire matches the intended front or rear role on the car and the wheel it will be mounted on. On a 1989 Lamborghini Countach, maintaining the staggered relationship between the 225/50R15 front and 345/35R15 rear sizes is essential.
Selection also depends on how the car will be used. A Countach kept primarily for display may place more emphasis on preserving its traditional stance, while a road-driven example still needs close attention to wheel condition, tire age, and any setup changes that could affect clearance or installation.
What rim-width specifications should I compare when choosing 1989 Lamborghini Countach tires?
Rim width matters because the 1989 Lamborghini Countach uses dramatically different front and rear tire widths on the same 15-inch rim diameter. A tire can share the correct diameter and still be unsuitable for the wheel if the wheel width is wrong for that specific tire and axle position.
Checking the actual wheel width on the car is especially important on collector supercars that may have changed hands, seen aftermarket wheel swaps, or been stored for long periods. Matching tire size to the correct wheel width helps preserve proper mounting shape, clearance, and the intended staggered character of the Countach.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Lamborghini Countach?
A period-style approach starts with preserving the Countach’s original-looking staggered layout: 225/50R15 in front and 345/35R15 in the rear. Because the 1989 Lamborghini Countach was defined visually by its extreme width difference between axles, keeping the correct front and rear sizes is central to the car’s overall presentation.
Appearance-led tire selection should still be grounded in fitment discipline. A restoration-oriented owner should confirm that the car retains the proper wheel arrangement and avoid treating any same-diameter tire as automatically appropriate, since the Countach’s stance depends heavily on the exact front-versus-rear size relationship.
Does correct tire fitment matter for a 1989 Lamborghini Countach restoration?
Yes, correct tire fitment matters greatly on a 1989 Lamborghini Countach restoration because the tires are part of the car’s visual identity as much as its road setup. The distinct staggered arrangement, with a much narrower front tire and much wider rear tire, contributes directly to the Countach’s shape and proportion.
A restoration-oriented project should verify wheel diameter, wheel width, and tire position before replacement, especially if the car has been modified or pieced together over time. When exact originality becomes the goal, marque-specific historical references and model-focused documentation are the right next step beyond basic size matching.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Lamborghini Countach?
Yes, modifications can affect tire fitment on a 1989 Lamborghini Countach even when the nominal tire sizes remain 225/50R15 front and 345/35R15 rear. Changes to wheel width, wheel offset, ride height, suspension components, or body clearance can all alter how those tires sit and move within the car.
A Countach with aftermarket wheels or suspension changes deserves a careful inspection before any replacement tire is mounted. Steering clearance at the front, inner and outer clearance at the rear, and the actual wheel specifications should all be confirmed so the staggered setup still works as intended.
What should I inspect before driving a 1989 Lamborghini Countach on new tires?
Before road use, inspect the wheels for condition, confirm the correct front and rear tire placement, and make sure inflation is appropriate for the mounted tires and the car’s setup. It also helps to check for rubbing, uneven ride height, loose suspension concerns, and any signs that the car’s alignment needs attention.
Collector vehicles often sit for long periods, so the rest of the tire system deserves a close look as well. Valve stems, wheel sealing surfaces, and the age and condition of any remaining tires on the car should be reviewed so the Countach returns to service on a matched and stable setup.
How should tires on a collector 1989 Lamborghini Countach be maintained?
Tires on a collector 1989 Lamborghini Countach should be inspected regularly for cracking, bulges, cuts, flat-spotting, air loss, and uneven wear. Proper inflation and periodic visual checks matter even when the car is driven sparingly, because low annual mileage does not prevent tires from aging.
Storage conditions also play a major role in long-term tire health. Keeping the Countach away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the tires, and occasional inspection of clearances and wheel condition makes it easier to catch developing fitment or aging problems early.
