1994 Lamborghini Tire Fitment Guide

1994 Lamborghini vehicles in this fitment range use two tire sizes, both for the Diablo: 245/40R17 at the front and 335/35R17 at the rear. Both are radial sizes for 17-inch wheels, but they are not interchangeable because the car uses a staggered setup with a narrower front tire and a much wider rear tire. The 245/40R17 products fit rims from 7.0 to 9.5 inches wide depending on the tire, while the 335/35R17 fits rims from 11.0 to 13.0 inches wide.

That means year and make alone are not enough if you are replacing only one tire or one axle pair. On a 1994 Lamborghini Diablo, the first step is confirming whether you need the front or rear size, then checking your wheel width against the tire you are considering. Owners replacing a full set should keep the staggered arrangement intact unless the car has been intentionally converted with a different wheel and tire package.

On a 1994 Lamborghini Diablo, 245/40R17 means the tire is 245 millimeters wide, has a 40-series aspect ratio, uses radial construction, and mounts on a 17-inch wheel. In this application, that size serves as the front tire. Available examples in this size carry W and Y speed ratings, so the exact speed capability depends on the tire you choose rather than the size code alone.

For a Diablo owner, the practical takeaway is that this code tells you both the physical format and the axle role. It is the narrower of the two sizes used on the car, so it should not be confused with the rear fitment just because both share the same wheel diameter. When comparing options, pay attention to the approved rim-width range and the speed rating printed on the sidewall.

On a 1994 Lamborghini Diablo, 335/35R17 means the tire is 335 millimeters wide, has a 35-series aspect ratio, uses radial construction, and fits a 17-inch wheel. That makes it the rear size in the car's staggered tire package. This size is substantially wider than the front tire and is designed for much wider wheels, with fitment in the 11.0- to 13.0-inch rim-width range.

That code matters because the rear tire is not just a larger version of the front; it is a separate fitment with its own wheel-width requirements and handling role. If your Diablo needs rear tires, confirm that you are working from the 335/35R17 size and not ordering by wheel diameter alone. On cars with aftermarket wheels, measuring actual wheel width before selection is especially important.

1994 Lamborghini Diablo fitments are covered by BFGoodrich and Michelin in the sizes here. BFGoodrich supplies the 245/40R17 front size through multiple g-Force series options, while Michelin covers the 335/35R17 rear size with Pilot Sport II. All of these are Blackwall radial tires, which suits the modern supercar character of the Diablo.

For most owners, brand choice is really a front-versus-rear conversation because the front and rear sizes do not share the same brand mix. If you are refreshing the whole car, look at the complete combination rather than choosing each axle in isolation. That approach helps preserve the intended visual balance and keeps the tire package aligned with the Diablo's original staggered layout.

1994 Lamborghini Diablo tires in these sizes are available with Blackwall sidewalls. That applies to both the 245/40R17 front fitment and the 335/35R17 rear fitment. For a 1990s Lamborghini supercar, Blackwall styling is the natural look and aligns with the period's emphasis on low-profile, performance-focused radial tires rather than decorative whitewall treatments.

That keeps the decision simple for an owner focused on appearance: the main comparison is tread design, brand, and speed rating rather than sidewall ornament. If your Diablo is being restored to a factory-correct visual presentation, Blackwall tires maintain the sharp, technical look these cars carried when new. Wheel finish, stance, and correct front-to-rear sizing will influence the final appearance more than sidewall styling on this application.

For the 1994 Lamborghini Diablo's 245/40R17 front size, the BFGoodrich g-Force Sport COMP-2 carries a 91W speed rating, fits 7.0- to 8.0-inch rims, weighs 26 pounds, and carries a maximum load figure of 1356 at 51 psi. The BFGoodrich g-Force Phenom T/A in the same size carries a 95Y speed rating, fits 8.0- to 9.5-inch rims, weighs 25.88 pounds, and carries a maximum load figure of 1521 pounds at 50 psi.

Those differences matter most if your Diablo has a wheel width near the edge of the approved range or if you want to match a higher speed rating at the front axle. The two tires share the same nominal size, but they are not interchangeable in every setup because their approved wheel-width ranges differ. Checking the actual front wheel width before choosing between them is the smart first step.

Rim width requirements on 1994 Lamborghini Diablo tires vary by size and, in the front size, by product. In 245/40R17, approved front-wheel widths range from 7.0 to 9.5 inches depending on the specific tire. In 335/35R17, the rear tire fits 11.0- to 13.0-inch rims. Both sizes use 17-inch wheel diameters, but wheel width still has to match the tire you choose.

That is especially important on a Diablo because many cars have seen wheel changes over the years. A tire that is correct in diameter may still be wrong for the wheel if the rim is too narrow or too wide for that product's approved range. Verifying wheel width before ordering is the best way to avoid fitment issues, particularly on the front axle where the available 245/40R17 tires do not all share the same range.

A 1994 Lamborghini Diablo uses 17-inch wheels front and rear, so both tire sizes share the same wheel diameter. That means the original wheels can remain part of the package so long as each tire is matched to its correct axle and the wheel width falls within the approved range for that specific tire. The front 245/40R17 and rear 335/35R17 are companion sizes, not alternate choices for the same wheel position.

For an owner keeping original wheels, the main checks are front-versus-rear placement and exact rim width. For an owner with aftermarket wheels, diameter alone is not enough; the wheel must also suit the tire's approved width window. Treat the shared 17-inch diameter as only one part of the fitment equation, especially on a car with as pronounced a stagger as the Diablo.

A 1994 Lamborghini should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Tire pressures should be checked before storage and again before the car goes back on the road. Because the Diablo uses low-profile radial tires, prolonged sitting can still create temporary flat-spotting even though radials generally recover better than older bias-ply designs.

Owners who store the car for long periods should move it slightly from time to time or support it in a way that reduces constant load on one contact patch. That is especially worthwhile on an exotic car that may spend more time displayed than driven. A clean floor, stable temperature, and regular pressure checks do more for tire life than occasional polishing or cosmetic care.

On a low-mile collector car such as a 1994 Lamborghini Diablo, tire age usually matters more than tread wear. A good rule is to begin close inspection once tires are around five to seven years old and to treat the ten-year mark as a serious replacement point even if the tread still looks strong. The DOT date code on the sidewall tells you when each tire was manufactured.

That matters because a lightly driven Diablo can age its tires out long before it wears them out. Heat cycles, storage conditions, and simple calendar time all affect the rubber's condition. If the car still carries older tires, especially on the rear where the size is specialized, replacing them can be as much a safety decision as a maintenance one before any spirited road use.

Tires on a 1994 Lamborghini should be inspected before every drive and again before any longer trip. Look for sidewall cracking, cuts, bulges, punctures, uneven wear, and pressure loss, and pay special attention to the inside sidewall if wheel design limits visibility from the outside. On a staggered car like the Diablo, compare front and rear condition separately because each axle works under different loads and tire widths.

A quick walkaround is useful, but a periodic hands-on inspection is better. Check pressure with an accurate gauge when the tires are cold, and inspect the spare as well if the car carries one. If the car has been parked for an extended time, include a short low-speed test for vibration or flat-spot sensation before committing to a longer highway drive.

A 1994 Lamborghini Diablo belongs to an era when low-profile radial tires were standard on high-performance exotic cars, and the fitment here reflects that with 245/40R17 fronts and 335/35R17 rears. Blackwall sidewalls are also appropriate to the period and the Diablo's design language. The exact brand fitted when new could vary by market, production timing, or wheel package, so confirming factory-delivery detail often requires original literature or a Lamborghini marque specialist.

For most restorations, getting the construction type, size, stagger, and sidewall look right will matter more than chasing a brand assumption. If the car is headed for marque judging, verify any market-specific tire details before final selection. The Diablo sits in a period where authenticity is tied closely to modern performance styling, so an obviously incorrect sidewall treatment or non-staggered setup would stand out quickly.

Correct tire fitment matters on a 1994 Lamborghini because judges and knowledgeable enthusiasts notice size, stance, sidewall appearance, and whether the car retains an era-appropriate staggered radial setup. A Diablo wearing mismatched front and rear proportions, an incorrect wheel diameter, or a sidewall style that looks out of period can distract from an otherwise strong restoration. On a 1990s supercar, visual correctness and mechanical correctness are closely linked.

For a show-focused owner, the safest route is to keep the 245/40R17 front and 335/35R17 rear relationship intact and use Blackwall radials that preserve the car's original character. Event standards can differ, especially between concours judging and marque-only gatherings, so it is wise to check with the sponsoring club before finalizing details. That extra step helps avoid losing points over something as visible as tire choice.

In the 1994 Lamborghini Diablo's 245/40R17 front size, the BFGoodrich g-Force COMP-2 A/S and g-Force Sport COMP-2 share a 91W speed rating and a 26-pound weight, but they differ in wheel-width range and load information. The COMP-2 A/S fits 8.0- to 9.5-inch rims, while the Sport COMP-2 fits 7.0- to 8.0-inch rims. The Sport COMP-2 also carries a maximum load figure of 1356 at 51 psi.

That makes the choice less about appearance and more about matching the actual front wheel and the intended use of the car. If your Diablo has a wider front wheel, the COMP-2 A/S aligns with that setup; if the wheel is narrower, the Sport COMP-2 may be the more appropriate match. Measuring the wheel and checking the sidewall marking on the tire before installation keeps the fitment process straightforward.

Yes, 1994 Lamborghini Diablo tires in these sizes can be suitable for highway driving when they are in good condition, correctly inflated, and matched to the proper wheel. The available 245/40R17 front tires carry W and Y speed ratings, which correspond to 168 mph and 186+ mph ceilings, while the rear 335/35R17 product uses a ZR-designated performance format. In normal highway use, the condition of the tire and the overall health of the car are usually more important than the raw speed capability printed on the sidewall.

A Diablo's brakes, suspension condition, alignment, and age-related mechanical condition all deserve as much attention as the tires before sustained road use. High speed ratings are reassuring, but they are not a substitute for a sound chassis and fresh rubber. If the car has sat for long periods, give the tires a careful inspection and a short shakedown drive before relying on them for extended interstate travel.

Inflation pressure on 1994 Lamborghini Diablo tires should follow the vehicle's factory recommendation for normal use, while still respecting the tire's own maximum load-and-pressure marking. In the 245/40R17 front size, one tire carries a maximum load of 1356 at 51 psi and another carries 1521 pounds at 50 psi. Those figures are not blanket running-pressure recommendations; they are the upper rated values for those specific tires.

The practical approach is to begin with the Lamborghini specification for the car and then confirm that your chosen tire is suitable for that use. Do not transfer a pressure figure from one front tire model to another, and do not apply front-tire pressure assumptions to the much wider rear size. On an exotic with low-profile tires, even a small pressure error can affect ride, wear, and steering feel.

Before taking a 1994 Lamborghini Diablo on a longer drive, inspect each tire for cracking, cuts, bulges, punctures, and abnormal wear, then verify cold pressure on all four corners. Confirm that the front 245/40R17 and rear 335/35R17 positions have not been mixed during prior service, and check the spare if the car carries one. A collector exotic should also have its wheels, valve stems, and wheel fasteners examined as part of the same pre-drive routine.

That tire check should happen alongside a broader mechanical inspection appropriate to a 1990s supercar, including fluids, belts, brakes, and cooling-system condition. A Diablo can cover distance well when prepared properly, but age-related issues rarely appear in just one system. Giving the tires and the rest of the car equal attention is the best way to turn a long drive into an enjoyable one instead of a recovery situation.
