1990 Ferrari F40 Spare Tire
The Ferrari F40, unlike many modern supercars, came equipped with a spare tire to help maintain performance even in the event of a puncture or other tire damage. This spare tire is an inflatable unit known as a "space saver," which is smaller than the vehicle's standard tires and designed to be used for temporary, emergency purposes. The space saver spare tire fits under the front hood of the vehicle, alongside the tool kit. The size of the F40's spare tire is 135/80R18, which is significantly narrower than its standard 245/35ZR19 front and 335/35ZR19 rear tires, but it shares the same 18-inch rim size. It's crucial to remember that this type of spare tire should only be used for driving short distances at reduced speeds, ideally to get to the nearest auto repair facility to have the damaged tire replaced or repaired.
1990 Ferrari F40 comes with 2 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Ferrari dealership to confirm the correct 1990 Ferrari F40 spare tire size.
