The 1990 Lamborghini Diablo arrived at the start of a new supercar decade, carrying forward the dramatic mid-engine, V12 Lamborghini formula with wider stance, sharper aerodynamics, and the kind of proportions that make tire fitment a central part of the car’s look and behavior. This exact car uses a staggered radial setup, with 245/40R17 in front and 335/35R17 in the rear on 17-inch rims. That means the real decision is less about finding one all-purpose size and more about matching the front and rear correctly while comparing available brands and tire series. For a Diablo, maintaining the intended stance, wheel compatibility, and overall balance matters every bit as much as tread design.
Which Tire Size Is Right for The 1990 Lamborghini Diablo
The 1990 Lamborghini Diablo uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. A 245/40R17 radial is used at the front and a 335/35R17 radial is used at the rear, both on 17-inch rims, so the first step is confirming which end of the car you are replacing before comparing product choices.
245/40R17 is a metric radial size in which 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 1990 Lamborghini Diablo, this is the front tire size and it plays a major role in steering response and visual proportion. Available choices in this size come from BFGoodrich in several g-Force series, all with Blackwall sidewalls. This is the size to evaluate when the goal is preserving the Diablo’s correct front fitment while comparing series character and wheel-width compatibility.
335/35R17 is a wide metric radial size that uses a 335-millimeter nominal section width, a 35-series profile, radial construction, and a 17-inch rim diameter. On the 1990 Lamborghini Diablo, this is the rear tire size, where width and profile are closely tied to the car’s stance and rear-wheel traction. Michelin offers this size in the Pilot Sport PS2 series with a Blackwall sidewall presentation. This is the tire size to review carefully when replacing rear tires, especially if wheel width or past modifications may have changed the car from its intended setup.
The covered Diablo fitment is straightforward, but the front and rear are separated as distinct fitment positions. Checking whether you need the Base Front or Base Rear application matters because the two sizes are not interchangeable even though both use 17-inch rims.

1990 Lamborghini Diablo Base Front
The 1990 Lamborghini Diablo Base Front uses the 245/40R17 radial size on a 17-inch rim. Tire selection at the front centers on keeping the correct fitment position while comparing available BFGoodrich series and confirming wheel-width compatibility before installation.
The 1990 Lamborghini Diablo Base Rear uses the 335/35R17 radial size on a 17-inch rim. Rear tire choice is mainly about preserving the intended staggered setup and making sure the wheel width and overall rear clearance still suit this very wide fitment.
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.

These 1990 Lamborghini Diablo tire FAQs focus on the staggered front-and-rear sizing, 17-inch rim fitment, available radial choices, and the practical checks that matter before mounting tires on a low-clearance exotic car.
Tire Size & Fitment
What tire size fits a 1990 Lamborghini Diablo?
The 1990 Lamborghini Diablo uses a staggered tire setup with two different radial sizes: 245/40R17 in the front and 335/35R17 in the rear. Both sizes mount on 17-inch rims, but they serve different positions on the car and should not be treated as interchangeable fitments.
That means the first step is identifying whether you are replacing front tires, rear tires, or the full set. A Diablo’s stance, clearance, and handling balance depend on keeping the front-to-rear sizing relationship intact, so wheel width and any past wheel or suspension changes should be checked before choosing replacements.
What size rim does a 1990 Lamborghini Diablo use?
The 1990 Lamborghini Diablo uses 17-inch rims with both of its primary tire sizes. The front 245/40R17 and the rear 335/35R17 are both built around a 17-inch wheel diameter, even though the tires differ significantly in width and profile.
Rim diameter is only part of the fitment picture on a Diablo. The front tire options and the rear tire option also call for different wheel-width ranges, so it is important to confirm the actual wheel dimensions on the car before mounting replacement tires, especially if the wheels are not the ones the car wore originally.
Does the 1990 Lamborghini Diablo Base Front use the same tire size as the Base Rear?
No. The 1990 Lamborghini Diablo Base Front uses 245/40R17, while the Base Rear uses 335/35R17. Both are radial tires for 17-inch rims, but the rear tire is much wider and is intended for the back of the car only.
That distinction matters when ordering or rotating tires because the Diablo does not use a square setup. Front and rear fitments have different width and wheel requirements, so replacement should be position-specific, with attention paid to the actual wheel dimensions and to any suspension or body changes that could affect clearance.
Choosing the Right Tire
What should I consider when choosing a 245/40R17 and 335/35R17 tire set for a 1990 Lamborghini Diablo?
Start with the correct staggered fitment: 245/40R17 for the front and 335/35R17 for the rear. From there, compare radial construction, wheel-width compatibility, tire series, and the intended use of the car, whether that means occasional road use, longer drives, or maintaining a more original-looking overall presentation.
A good Diablo tire choice is one that preserves the front-to-rear balance of the car without forcing a mismatch in wheel width or profile. Looking at the complete set rather than buying one size in isolation helps maintain visual proportion and avoids mounting a tire that suits the size code but not the actual wheel or chassis setup.
What brands offer tires for the 1990 Lamborghini Diablo?
BFGoodrich and Michelin both have applicable tires for the 1990 Lamborghini Diablo. BFGoodrich covers the 245/40R17 front size, while Michelin offers the 335/35R17 rear size, so brand selection is tied to the car’s staggered front and rear fitment rather than one brand supplying every position.
That makes it important to think in terms of axle position first and brand second. A Diablo owner comparing tires should look at which brand serves the front or rear application needed, then review tire series, wheel-width compatibility, and the role each tire will play in keeping the car’s overall setup consistent.
What tire series are available for the 1990 Lamborghini Diablo?
For the 1990 Lamborghini Diablo, the front 245/40R17 size is available in BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. The rear 335/35R17 size is available in the Michelin Pilot Sport PS2 series.
Series choice matters because it helps distinguish the available products beyond size alone. Once the correct front or rear position is confirmed, compare the series alongside wheel-width requirements and any load details shown for that specific tire, especially on an exotic car where width, profile, and chassis clearance all work closely together.
Restoration & Appearance
Which tire should I choose for a period-style 1990 Lamborghini Diablo?
A period-style 1990 Lamborghini Diablo should keep its staggered 17-inch radial fitment, using 245/40R17 in front and 335/35R17 in the rear. Since the available tires here are all modern radial designs with Blackwall sidewalls, the appearance decision is mostly about preserving the correct proportions and overall stance rather than choosing between vintage sidewall treatments.
For a restoration-oriented car, maintaining the intended front-to-rear relationship usually matters more than chasing unnecessary visual variation. The best next step is to confirm the car’s current wheel dimensions and compare the available tire series with the level of road use planned, especially if the Diablo has changed hands or has seen aftermarket wheel updates.
Does correct tire fitment matter for a 1990 Lamborghini Diablo restoration?
Yes, correct tire fitment matters a great deal on a 1990 Lamborghini Diablo restoration because the car relies on a very specific staggered radial arrangement. The front 245/40R17 and rear 335/35R17 sizes contribute to the Diablo’s visual balance, wheel fill, and intended relationship between steering and rear-drive traction.
Even on a car aimed more at display than regular mileage, tire size still affects how authentic the finished restoration looks in profile. Owners focused on originality should verify the actual wheel setup on the car and compare it with marque-specific historical references before making any change that alters the established front-and-rear tire proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1990 Lamborghini Diablo?
Yes. Modifications can change how well 245/40R17 front and 335/35R17 rear tires suit a 1990 Lamborghini Diablo, even when the nominal size remains the same. Aftermarket wheels, altered wheel widths, suspension changes, ride-height adjustments, or body modifications can all influence clearance and how the tire sits in the wheel opening.
That is especially important on a low, wide exotic with limited room around the tire. Before mounting new tires, confirm the actual wheel diameter and width on the car, then check steering clearance in front and body or suspension clearance at the rear so the replacement matches the setup currently on the vehicle.
What should I inspect before driving a 1990 Lamborghini Diablo on new tires?
Before driving a 1990 Lamborghini Diablo on new tires, inspect wheel condition, tire pressure, valve stems, and the basic clearance around both front and rear fitments. It also helps to confirm that the front 245/40R17 and rear 335/35R17 tires are mounted in the correct positions and that there is no interference at full steering lock.
A brief post-installation check is just as important. After the first miles, recheck pressure, look for any signs of rubbing, and confirm that the car tracks normally. On a vehicle with wide rear tires and very low bodywork, small wheel or alignment issues can become noticeable quickly once the new tires are on the road.
How should 245/40R17 and 335/35R17 tires on a collector 1990 Lamborghini Diablo be maintained?
Collector-use tires on a 1990 Lamborghini Diablo should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Look over both the 245/40R17 front tires and 335/35R17 rear tires for cracking, cuts, bulges, unusual wear, or slow air loss, especially if the car spends long periods parked.
Storage conditions matter because low-use exotics often age their tires before they wear them out. Keeping the Diablo away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and occasional inspections of wheel condition and tread surface can catch problems early before the car is taken back out for road use.
