Ferrari 308 Tires
1973–1980 Ferrari 308 GT4 2+2 Tires
To some, the Ferrari 308 GT4 2+2 will always still be a Ferrari Dino, though it has moved up to having a V8 engine, it is still a small Ferrari, it doesn’t have 12 cylinders. Another similarity with the earlier Dino 246 is that the 308 GT4 2+2 fitted the same tires with 205/70VR14 Michelin XWX tires. Michelin XWX tires are so strongly associated with Ferrari in this period. The other option to consider would be the 205/70WR14 PIRELLI CINTURATO ™ CN36.
308 GTB and 308 GTS Tires 1975–1980
Running along side the 308 GT4 the 308GTB and the Targa top version the 308 GTS epitomised the classic wedge shape of the top-notch sports cars of this period, and continued to fit 14” wheels and the 205/70VR14 Michelin XWX.
Ferrari 308 GTBi, GTSi 1980–1982 and 1982–1985 Ferrari 308 qv Quattrovalvole Tires
Although the Michelin TRX tires of the period had been around for a while it wasn’t until the the fuel injection version of the 308GTB that Ferrari upped the grip levels by fitting 220/55VR390 Michelin TRX tires, of course this was also fitted to the 308GTS and they continued through to the next engine generation with 4 valve per cylinder engine the 308 qv (Quattrovalvole). Michelin TRX tires are extremely specialist and were only fitted to the world's best cars.
16” Ferrari 308 Tires
Though the Michelin TRX or 14” Michelin XWX were standard on the classic Ferrari wedge, the 308 GTB or GTS, in its various guises, the later Ferrari 328 did fit 16” wheels. Through out the production of the Ferrari 308 there was also a 16” wheel option. The tires of choice then, as they are today, is the 205/55YR16 PIRELLI CINTURATO™ P7 N on the front with the 225/50YR16 PIRELLI CINTURATO™ P7 N on the rear. These are still a great option and will handle far better than any other modern 16” tire fitted to these ‘70s and 1980s iconic wedge cars because a modern tire is designed to perform in a very different environment. The Pirelli P7 is designed to be presented to the road in the same manner that the Ferrari 308 chassis behaves.
It is great to have such an excellent 16” classic tire available as the Pirelli Cinturato P7, and like the Michelin XWX, TRX and Pirelli Cinturato these genuine period tires do benefit from top quality modern rubber compounds from 2 of the worlds best tire manufacturers and their improved quality control systems. The Ferrari 308 would have been subtly set adjusted to suit the tires that it left the factory with. So although the 16” Pirelli P7 is the best tire for the Ferrari 308 on 16” wheels, each individual Ferrari 308 will perform at its best, as a road car, on its original wheel and tire set up.
