The 1985 Lamborghini Countach sits in the era when exotic supercars became sharply wedged, visually dramatic, and unmistakably tied to high-speed European performance. By this point, the Countach had evolved into a wide-body, poster-car machine whose tire stance is a major part of its identity. The 1985 Lamborghini Countach uses radial tires in two distinct sizes, with 225/50R15 at the front and 345/35R15 at the rear, both on 15-inch rims. That staggered setup makes tire selection as much about preserving the car’s proportions as matching fitment. Owners should approach replacement tires with close attention to front-versus-rear sizing, wheel confirmation, and the appearance the car presents from every angle.
Which Tire Size Is Right for The 1985 Lamborghini Countach
The 1985 Lamborghini Countach uses two primary tire sizes rather than one shared fitment. Both are radial tires on 15-inch rims, but the front and rear positions use very different dimensions, so the first step is confirming which axle you are replacing for and whether the car still has its proper wheel setup. Once that is settled, the decision becomes choosing the right tire within the correct front or rear size.
225/50R15 is a metric radial size in which 225 represents nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1985 Lamborghini Countach, this is the front tire size and it plays a major role in maintaining the car’s intended staggered stance. Its lower-profile metric format reflects the Countach’s performance-era fitment rather than an older bias-ply convention. Choosing this size correctly matters because the front axle sets steering response, visual balance, and clearance within a setup that is very different from the car’s much wider rear tires.
345/35R15 is a metric radial size where 345 indicates a very wide nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 15 is the rim diameter in inches. On the 1985 Lamborghini Countach, this is the rear tire size and it defines much of the car’s unmistakable wide-track appearance. The unusually broad rear fitment is a key part of the Countach tire story, not just a dimensional detail. Selecting this size calls for careful wheel confirmation and attention to the rear-specific setup rather than treating it as interchangeable with more common 15-inch radial sizes.
The covered Countach fitment is straightforward in one sense and highly specific in another. The 5000 quattrovalvole uses a dedicated front-and-rear staggered setup, so identifying the axle position matters just as much as confirming the vehicle itself.

1985 Lamborghini Countach 5000 quattrovalvole Front
The 1985 Lamborghini Countach 5000 quattrovalvole Front uses the narrower front radial fitment within the car’s staggered 15-inch setup. Tire selection here should focus on preserving the proper front application rather than trying to match the dramatic rear size or treating all Countach tires as the same.
The 1985 Lamborghini Countach 5000 quattrovalvole Rear uses the car’s exceptionally wide rear radial fitment on a 15-inch wheel. That makes rear tire selection a distinct decision, especially for owners who want to retain the Countach’s characteristic stance and verify wheel compatibility before replacement.
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
Questions about 1985 Lamborghini Countach tires usually come down to the staggered front and rear sizes, 15-inch rim fitment, construction, and what to inspect before putting a low-use exotic back on the road.
Tire Size & Fitment
What tire size fits a 1985 Lamborghini Countach?
The 1985 Lamborghini Countach uses two different tire sizes: 225/50R15 at the front and 345/35R15 at the rear. Both are radial tires and both mount on 15-inch rims, but they are not the same size front to rear.
That staggered arrangement means the first question is not simply whether a tire is 15-inch, but whether it belongs on the front or rear axle. Before ordering replacements, confirm the wheel setup on the car and make sure any prior wheel or suspension changes have not altered the original front-and-rear fitment layout.
What size rim does a 1985 Lamborghini Countach use?
The 1985 Lamborghini Countach uses 15-inch rims with both of its primary tire sizes. The front 225/50R15 and rear 345/35R15 share the same rim diameter even though the tires differ dramatically in width and profile.
Rim diameter is only one part of the fitment picture on a Countach. Wheel width and the actual front-versus-rear wheel pairing should also be checked, especially on a collector car that may have seen aftermarket wheel changes or prior restoration work. Matching the 15-inch diameter alone does not confirm the full setup.
Why does the 1985 Lamborghini Countach have more than one tire size?
The 1985 Lamborghini Countach has more than one tire size because it uses a staggered setup, with 225/50R15 in front and 345/35R15 in the rear. This was part of the car’s performance-focused layout and also a major part of its visual character.
For the owner, that means tire selection depends on axle position rather than a single all-around size. Front and rear tires should be treated as separate fitment decisions, and the car should be checked for its actual wheel arrangement before replacement. That helps preserve both proper fitment and the Countach’s distinctive stance.
Choosing the Right Tire
What should I consider when choosing a 225/50R15 tire for a 1985 Lamborghini Countach?
A 225/50R15 for a 1985 Lamborghini Countach should first be chosen as the correct front tire size, not simply as a generic 15-inch radial. The size itself sets the baseline, and then the focus shifts to matching the tire to the car’s front-wheel application and overall staggered setup.
The practical checks include confirming that the front wheels are the proper diameter and width, and making sure the car still carries its intended front-versus-rear pairing. On a low-production exotic, previous wheel changes can complicate replacement, so the safest approach is to verify the current wheel dimensions and front clearance before installing new tires.
What should I consider when choosing a 345/35R15 tire for a 1985 Lamborghini Countach?
A 345/35R15 for a 1985 Lamborghini Countach should be chosen with the understanding that it is the rear tire size in a highly specialized staggered fitment. This is not just a large 15-inch radial; it is a defining rear application that shapes both the car’s appearance and its intended setup.
Rear wheel confirmation matters as much as the tire size itself. The owner should verify the actual rear wheel dimensions, inspect for suspension or body changes, and make sure the replacement tire suits the car’s rear-specific clearance requirements. On a Countach, getting the rear tire choice right is central to preserving the car’s characteristic stance.
How do I choose between the available 1985 Lamborghini Countach tires?
Choosing between 1985 Lamborghini Countach tires starts with identifying whether the tire is for the front or rear axle, since the car uses 225/50R15 in front and 345/35R15 in the rear. Once axle position is clear, the correct metric radial size becomes the primary selection point.
After that, compare the tire against the wheel setup actually on the car rather than assuming every Countach remains untouched. Collector vehicles are often fitted with replacement wheels or altered suspension over time, so the best comparison points are wheel dimensions, clearance, and whether the tire preserves the car’s intended staggered visual balance.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Lamborghini Countach?
A period-style 1985 Lamborghini Countach tire choice starts with keeping the car’s correct staggered metric radial sizing intact: 225/50R15 at the front and 345/35R15 at the rear. Those dimensions are a major part of the Countach’s 1980s exotic presentation and should frame any restoration-oriented decision.
Appearance matters on a Countach because the tire-to-body relationship is so visually dramatic. Owners pursuing a more authentic look should verify wheel dimensions and study marque-specific historical references before finalizing a setup, especially if the car has changed hands, been modified, or no longer wears the wheel and tire arrangement it had earlier in life.
Does correct tire fitment matter for a 1985 Lamborghini Countach restoration?
Correct tire fitment matters greatly on a 1985 Lamborghini Countach restoration because the car’s shape, ride height impression, and wide rear stance all depend on maintaining the proper front and rear sizing relationship. Using the right 15-inch radial sizes helps preserve the proportions that define the model.
Restoration-minded owners should think beyond simple diameter and focus on the complete presentation of the car. A mismatched front-to-rear setup can change the visual balance quickly, so checking actual wheel dimensions, axle position, and any prior modifications is an important part of getting the restored car to look coherent and properly sorted.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Lamborghini Countach?
Yes, modifications can affect tire fitment on a 1985 Lamborghini Countach even when the car still appears to use 15-inch wheels. Changes to wheel width, wheel offset, suspension height, alignment settings, or bodywork can alter how the 225/50R15 front and 345/35R15 rear tires sit in the car.
That is especially important on a Countach because the rear tire is unusually wide and the overall setup is highly specific. Any owner dealing with an imported, restored, or previously customized car should inspect wheel dimensions and tire clearance carefully before replacement. A staggered exotic fitment leaves less room for assumptions than a more conventional classic-car setup.
What should I inspect before driving a 1985 Lamborghini Countach on new tires?
Before driving a 1985 Lamborghini Countach on new tires, inspect the wheels for correct front and rear placement, look over the suspension and steering components, and make sure the tires are seated properly and inflated appropriately. It also helps to check that the car rolls and steers without any obvious interference.
Collector exotics often spend long periods parked, so the surrounding condition matters as much as the fresh tires. Brake operation, alignment condition, wheel fastener security, and any signs of rubbing should be reviewed before regular road use. A short, careful test drive is a sensible way to confirm that the staggered setup behaves as expected.
How should tires on a collector 1985 Lamborghini Countach be maintained?
Tires on a collector 1985 Lamborghini Countach should be maintained with regular pressure checks, routine visual inspection, and close attention to age-related condition. Sidewall cracking, bulges, cuts, uneven wear, and persistent air loss all deserve attention, especially on a car that may see limited seasonal use.
Storage conditions matter because infrequent use can be harder on tires than steady driving. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires over time. It is also wise to inspect both the front 225/50R15 and rear 345/35R15 positions separately, since each axle carries a very different tire application.
