The 1986 Lamborghini Countach sits squarely in the era when exotic supercars turned dramatic styling into a defining part of the driving experience. Its low profile, wide stance, and unmistakable wedge shape make tire fitment especially important because the visual balance of the car depends so heavily on front-to-rear proportion. This Countach uses staggered radial sizing, with 225/50R15 in front and an exceptionally wide 345/35R15 in the rear, both on 15-inch rims. The real decision is less about choosing between multiple fitment systems and more about matching the correct front and rear sizes while preserving the car's intended stance, wheel compatibility, and road-ready condition.
Which Tire Size Is Right for The 1986 Lamborghini Countach
The 1986 Lamborghini Countach uses two primary tire sizes, and they are position-specific rather than interchangeable. Both are radial tires on 15-inch rims, with 225/50R15 used at the front and 345/35R15 used at the rear, so the first step is confirming which end of the car you are fitting before selecting a tire.
225/50R15 is a metric radial size in which 225 indicates nominal section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 15 is the rim diameter in inches. On the 1986 Lamborghini Countach, this is the front tire size and it plays a major role in steering feel, clearance, and the car's intended staggered setup. Its lower-profile metric format reflects the Countach's period supercar tire design rather than an older bias-ply convention. Choosing this size means keeping the front fitment aligned with the car's original front-to-rear sizing strategy and verifying wheel condition before road use.
345/35R15 is a very wide metric radial size, with 345 representing nominal section width in millimeters, 35 identifying the aspect ratio, R marking radial construction, and 15 indicating rim diameter. On the 1986 Lamborghini Countach, this size belongs at the rear, where the car's dramatic stance and broad footprint are central to both appearance and proper setup. The unusually wide section is a defining part of Countach fitment, so it should be treated as a dedicated rear specification rather than a general 15-inch tire option. Selecting this size starts with confirming the correct rear wheel and checking clearance on an unaltered or modified car.
Sub-model fitment on the 1986 Lamborghini Countach is straightforward in name but critical in position, because the covered configuration separates front and rear tire sizes. Checking the exact front or rear application matters before choosing a tire, since the Countach uses a staggered setup rather than the same size at all four corners.

Frequently Asked Questions
These FAQs focus on the staggered front and rear tire sizes used on the 1986 Lamborghini Countach, along with rim fitment, product-selection priorities, restoration-minded appearance, and the checks worth making before putting a collector-era supercar back on the road.
Tire Size & Fitment
What tire size fits a 1986 Lamborghini Countach?
The 1986 Lamborghini Countach uses a staggered radial tire setup with 225/50R15 at the front and 345/35R15 at the rear. Both sizes are part of the vehicle's primary fitment and both mount on 15-inch rims, but each size belongs to a specific axle position rather than serving as a universal four-corner size.
That means the first fitment question is whether the tire is for the front or rear of the car. Mixing up the positions can upset the Countach's intended stance and wheel compatibility, so it is smart to confirm the actual wheel size and placement on the vehicle, especially if it has seen wheel changes or other modifications over time.
What size rim does a 1986 Lamborghini Countach use?
The primary tire fitments for the 1986 Lamborghini Countach both use 15-inch rims. The front size is 225/50R15 and the rear size is 345/35R15, so the rim diameter stays the same while the tire width and profile differ significantly between the two ends of the car.
Rim diameter is only one part of the fitment picture on a Countach. Wheel width and overall wheel setup still matter, particularly with the extra-wide rear tire, so confirming the actual front and rear wheels on the car is important before choosing tires. That is especially true if the car has aftermarket wheels or has been stored for long periods.
What does 345/35R15 mean on a 1986 Lamborghini Countach?
345/35R15 is a metric radial tire size used at the rear of the 1986 Lamborghini Countach. The 345 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 15 is the rim diameter in inches.
On this Countach, that size is more than just a specification line because it is a major part of the car's wide rear stance. Understanding the code helps when comparing tires and checking wheel compatibility, but the real next step is making sure the rear wheel, suspension condition, and body clearance still suit the intended tire before the car goes back into regular road use.
Choosing the Right Tire
What should I consider when choosing a 225/50R15 tire for a 1986 Lamborghini Countach?
Choosing a 225/50R15 tire for a 1986 Lamborghini Countach starts with matching the correct front size and retaining radial construction. Because this is the front fitment, the tire needs to suit the 15-inch front wheel and preserve the Countach's staggered relationship with the much wider 345/35R15 rear tire.
Beyond the size itself, the key considerations are the actual wheel setup, the car's condition, and how closely the tire supports the intended appearance and road use of the vehicle. A Countach that still carries its original-style wheel arrangement calls for careful front-to-rear matching, while a modified car deserves an extra check of wheel width, steering clearance, and suspension condition.
What should I consider when choosing a 345/35R15 tire for a 1986 Lamborghini Countach?
Selecting a 345/35R15 tire for a 1986 Lamborghini Countach means preserving the dedicated rear fitment that gives the car its distinctive wide-back stance. This is a radial size for a 15-inch rear rim, and it should be treated as a position-specific rear tire rather than a general replacement based only on diameter.
The practical considerations go beyond reading the sidewall code. Rear wheel condition, actual wheel width, suspension health, and body clearance should all be checked before installation, particularly on a collector car that may have been altered or stored. Keeping the rear tire properly matched to the front 225/50R15 size is also important for maintaining the Countach's intended visual and fitment balance.
How do I choose between the available 1986 Lamborghini Countach tires?
The main choice for a 1986 Lamborghini Countach is not between several primary fitment families, but between the correct front and rear sizes and the condition of the wheels they mount on. The car uses 225/50R15 in front and 345/35R15 in the rear, both in radial construction on 15-inch rims.
A good selection process begins with confirming axle position, then checking whether the car remains on its intended wheel setup. After that, focus on fitment integrity, collector-car appearance goals, and how the car will actually be used. A Countach prepared for occasional display and short drives may call for different priorities than one being readied for more regular road miles.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Lamborghini Countach?
A period-style 1986 Lamborghini Countach should retain its staggered radial layout, using 225/50R15 at the front and 345/35R15 at the rear. Those sizes are central to the car's visual character, especially the pronounced rear width that defines the Countach's late-era supercar stance.
For a restoration-oriented result, the goal is usually to preserve the car's intended front-to-rear proportion rather than simply finding any 15-inch tire. Owners pursuing exact historical originality should compare their car against marque documentation and restoration references, while also confirming that the wheels currently on the car still match the fitment needed for those position-specific sizes.
Does correct tire fitment matter for a 1986 Lamborghini Countach restoration?
Correct tire fitment matters a great deal on a 1986 Lamborghini Countach restoration because the car's appearance depends heavily on its staggered proportions. The front 225/50R15 and rear 345/35R15 sizes are not cosmetic afterthoughts; they shape how the car sits, fills the arches, and presents its characteristic wedge-and-wide-rear profile.
Restoration-minded buyers should look at tire fitment as both a mechanical and visual decision. A mismatched size can alter the car's stance even before the car turns a wheel, so it pays to confirm the actual front and rear wheel arrangement, inspect the wheels for age-related issues, and choose tires that respect the Countach's original-style size relationship.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Lamborghini Countach?
Yes, modifications can affect tire fitment on a 1986 Lamborghini Countach, even when the intended tire sizes remain 225/50R15 in front and 345/35R15 in the rear. Changes to wheels, suspension height, alignment settings, bodywork, or steering components can all influence how those tires sit and clear the car.
That is why a modified Countach should be measured and inspected rather than treated like a stock example. The front fitment needs enough steering and suspension clearance, while the rear fitment needs proper wheel support and body clearance for its extra width. Even small setup changes can matter on a low, tightly packaged exotic with a staggered tire arrangement.
What should I inspect before driving a 1986 Lamborghini Countach on new tires?
Before driving a 1986 Lamborghini Countach on new tires, inspect the wheels, valve stems, and mounting surfaces, then verify that 225/50R15 is installed at the front and 345/35R15 at the rear. It is also wise to check tire pressure, look for any obvious interference, and make sure the suspension and steering components are in sound condition.
Collector cars can hide age-related issues even when tread looks fine, so the inspection should include signs of cracking, cuts, bulges, uneven wear, or air loss on any existing tires being evaluated. A short, careful road test after installation helps confirm that the Countach tracks properly and that no clearance issue appears once the car is under load.
How should tires on a collector 1986 Lamborghini Countach be maintained?
Tires on a collector 1986 Lamborghini Countach should be maintained with regular pressure checks, routine visual inspection, and attention to storage conditions. Because the car uses a staggered setup with 225/50R15 front and 345/35R15 rear tires, each axle should be checked individually for wear pattern, condition, and proper mounting position.
Long periods of inactivity can be as important as mileage on a collector car, so storage away from prolonged sunlight, heat, moisture, and ozone sources is worthwhile. Occasional inspection for sidewall cracking, flat spotting, bulges, and air loss helps catch problems early, and any Countach returning to the road after long storage deserves a close wheel and suspension check as well.
