1991 Lamborghini Diablo Tires

The 1991 Lamborghini Diablo uses a staggered radial tire setup with 245/40R17 at the front and 335/35R17 at the rear. Both sizes are built for 17-inch rims, and each one serves a specific position on the car rather than functioning as an all-around fitment.

That means the first step is identifying whether the tire replacement is for the front or rear axle. A Diablo should be checked carefully for any wheel changes, altered suspension height, or other modifications before ordering, because the correct front and rear pairing matters just as much as the individual size itself.

The 1991 Lamborghini Diablo uses 17-inch rims with both of its primary tire sizes. The front 245/40R17 and rear 335/35R17 share the same rim diameter, even though they differ substantially in width and profile to create the car's staggered setup.

Rim diameter is only part of the fitment picture on a Diablo. Wheel width still needs to match the tire you are considering, especially with such a wide rear fitment, and any aftermarket wheels should be measured rather than assumed to match the original specification simply because they are also 17-inch wheels.

On a 1991 Lamborghini Diablo, 335/35R17 is the rear tire size. The 335 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches.

That code tells you this is an extremely wide low-profile rear tire designed for a 17-inch wheel, not a front fitment and not a universal Diablo size. Owners should still confirm the actual rear wheel width and inspect for suspension, ride-height, or body changes that could alter clearance on a car with such a wide rear tire.

Choosing a 245/40R17 for a 1991 Lamborghini Diablo starts with keeping the correct front size and confirming the wheel width on the car. In this size, available choices come from BFGoodrich in several g-Force series, all in Blackwall radial construction.

Once the front size is confirmed, compare the tire series with the wheel-width range and any other meaningful specifications that affect how the tire suits the car's setup. It also helps to think in pairs, since the Diablo relies on a matched staggered arrangement and the front tire should be selected with the rear fitment in mind.

Tire choices for the 1991 Lamborghini Diablo include BFGoodrich and Michelin. BFGoodrich appears in the 245/40R17 front size with multiple g-Force series, while Michelin covers the 335/35R17 rear fitment with a Pilot Sport PS2 radial.

Brand choice here is closely tied to tire position because the front and rear sizes do not share the same product assortment. Instead of trying to choose one brand in the abstract, it makes more sense to verify which end of the car needs tires first, then compare the relevant series, wheel-width specifications, and overall front-to-rear compatibility.

For the 1991 Lamborghini Diablo, the 245/40R17 front size is available in BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. The 335/35R17 rear size is available in the Michelin Pilot Sport PS2 series.

Those series distinctions matter because the product choices are not simply duplicates in the same size. The practical approach is to match the correct tire series to the front or rear position needed, then review wheel-width compatibility and any specification differences that could matter on a Diablo with its very wide rear fitment.

A period-style 1991 Lamborghini Diablo tire choice starts with preserving the car's staggered 17-inch radial setup: 245/40R17 in front and 335/35R17 in the rear. Since the available options are Blackwall radials, the visual character remains in line with the clean, low-profile exotic presentation expected from an early 1990s supercar.

For a restoration-minded owner, the key is keeping the proper front and rear relationship rather than chasing an unrelated modern size that alters the car's stance. Exact originality questions should be checked against marque-specific references, but from a practical standpoint the correct sizes and proper wheel compatibility are the foundation of a convincing period-style result.

Correct tire fitment matters a great deal on a 1991 Lamborghini Diablo restoration because the car's appearance depends heavily on its staggered proportions. The combination of 245/40R17 front and 335/35R17 rear tires is a major part of the car's visual balance as well as its intended wheel-and-tire relationship.

Restoration-oriented buyers should look beyond tread alone and pay attention to the right size, radial construction, and wheel match at each end of the car. A tire that is close in spirit but wrong in width, profile, or position can change the stance noticeably, so careful confirmation is especially worthwhile on a Diablo.

Yes, modifications can affect tire fitment on a 1991 Lamborghini Diablo even when the tire size appears correct. Aftermarket wheels, suspension changes, altered ride height, brake upgrades, or body adjustments can all change how a 245/40R17 front or 335/35R17 rear tire sits within the available space.

A Diablo should be measured as it currently exists, not as a stock car in theory. Check wheel width, wheel diameter, and clearance at full steering lock and through suspension travel, especially at the front, while the rear should be inspected for inner and outer clearance before assuming the original staggered fitment still works unchanged.

Before driving a 1991 Lamborghini Diablo on new tires, inspect the wheels for damage, confirm that the front and rear sizes are installed in the correct positions, and check inflation pressure carefully. It also makes sense to look at alignment condition, valve stems, and any signs that the car's suspension or steering components need attention.

An early drive should be treated as a verification run rather than a full-speed outing. Watch for rubbing, vibration, pulling, or unusual contact marks, and recheck pressure after the tires have had some use. On a low, wide exotic like the Diablo, small setup issues can become obvious quickly once the car returns to regular road use.

Before a longer drive in a 1991 Lamborghini Diablo, confirm tire pressure, inspect tread and sidewalls for cuts or bulges, and make sure there is no slow air loss. The front and rear tires should also be checked for age-related cracking if the car spends long periods stored between drives.

Collector and exotic cars often accumulate less mileage than their tire condition suggests, so visual inspection matters as much as tread depth. It is also smart to verify lug torque, look for any signs of rubbing, and check that the car still sits correctly after storage, especially when running a very wide 335/35R17 rear tire.
