Ferrari Testarossa Tires
On the first edition Ferrari Testarossa, 240/45VR415 Michelin TRX GT and 280/45R415 Michelin TRX tires were mounted on centre lock wheels. Unfortunately, although Michelin still manufactures TRX tires, the 280/45R415 TRX is no longer available. The 280/45VR415 Michelin TRX has not been available since 2011. Instead, we recommend installing 16-inch wheels.
Later iterations of the Ferrari Testarossa featured the same knock off wheels but in 16" in 1986. The wheels were then changed to the more standard Ferrari 5 bolt configuration in 1988. They were outfitted with Michelin MXX or Goodyear Gatorback tires in 225/50ZR16 front and 255/50ZR16 rear sizes.
These are no longer produced; however, Michelin does produce these same dimensions in the Pilot Sport directional tread pattern 225/50ZR16 Michelin Pilot Sport and 255/50ZR16 Michelin Pilote Sport, which are ideal for the Ferrari Testarossa. Pirelli also manufactures the P-Zero system, which was used on Pirelli's Testarossa tires during this time period. The front tires were 225/50R16 P-Zero Directionale, while the rear tires were 255/50R16 P-Zero Asimmetrico.

TRX Testarossa Tires
The 240/45VR415 Michelin TRX GT is still in production, but the 280/45VR415 TRX is not. The Michelin tire 280/45VR415 TRX was designed specifically for the rear of Ferrari's Testarossa. TRX tires are among the most difficult high-quality tires to manufacture. There is only a small amount of machinery capable of producing such an exceptional 280/45YR415 tire size left, and demand was extremely low. Michelin has been unable to justify the continued production of the 280/45 VR 415 TRX Ferrari Testarossa tire, which has been out of production since 2011.

In 1986, Pirelli created the P-Zero Asimmetrico. Its tread compounds were developed on the racetrack, and the P-Zero Asimmetrico carcass is a complex structure that includes Kevlar reinforcement. And, of course, there's the well-known P-Zero Asimmetrico tread pattern, which features an asymmetric series of different tread patterns across the foot print, each performing a different function depending on where they are on the tread. All of this contributes to the 255/50 YR 16 Pirelli P-Zero Asimmetrico being a fantastic tire.

History of the Ferrari Testarossa
Ferrari Testarossa in Italy
The Testarossa was unveiled in September 1984 at the Paris Motor Show as the successor to the Ferrari 512 Berlinetta Boxer. The Testarossa, designed by the famed Pininfarina, was not Ferrari's first car to bear the name. The Testarossa name was given to a number of race-bred Ferraris in 1950. The name is derived from the distinguishable red cam covers (Testarossa meaning red-head). The Ferrari Testarossa of the 1980s was designed primarily for the US market and first appeared in showrooms in 1985.
The Ferrari Testarossa uses a double-wishbone suspension with coil-over springs at the rear to help with the increase in weight. The body of the car was made up of aluminium with steel doors and roof. The engine was a modified version of the one found in the 512 Berlinetta Boxer, with 4 valves per cylinder, Marelli electronic ignition; K-Jetronic fuel injection and was capable of producing 390 bhp from the 4943cc horizontally mounted 12 cylinder engine, capable of 0 to 60mph in just over 5 seconds and won't stop pulling until it hits an impressive 180mph!Probably the Ferrari Testarossa's most easily recognisable trait was its sculpted side vents that gave the impression that the car was travelling at 100mph even when it was standing still, necessitated by the twin radiators at the rear. At 6ft 6in wide the Ferrari Testarossa was a large car, to say the least, however, it still managed to be extremely light and agile to drive. The Testarossa's acceleration and road holding were tremendous and more than capable of passing anything else on the road (if the road was wide enough!). Almost 7200 examples of the Ferrari Testarossa had been built when production ended in 1992.
