Ferrari 308

The Ferrari 308 GT/4, GTB & GTS fitted 220/55VR390 Michelin TRX
The Ferrari 308 is not really from the age when Ferrari were fitting wire wheels to their cars- However some people do enjoy the retro-retro look, and the option is there.

The first Ferrari 308 was the Dino 308 GT4 which came out under the Dino badging (The Dino in the name shows it is a non V12 model of Ferrari) At this time Ferrari were often associated with the fantastic Michelin XWX tires, as the highest speed rated tires of the period.
Today Michelin still make the205/70VR14 Michelin XWXthat so many 308 Dino GT4 cars left the factory fitted with and they still maintain the W (170mph) speed rating

Possibly the more famous incarnation of the 308 Ferrari is the one we associate with Magnum PI, the fantastic wedge that was the 308 GTB (Berlinetta) or the 308 GTS (Spider). These cars including the early fiberglass models continued with the 14" wheels and fitted the 205/70VR14 Michelin XWX. However It is worth checking, because the is a possibility that your car is fitted with the later 308 GTBi or 308 GTSi 390mm wheels- In which case it will need to fit 20/55VR390 Michelin TRX tires

Ferrari introduced the fuel injection system to its 308 GTB and GTS cars in 1980, which is shown by the little "i" in there name- By this time Michelin had made an enormous leap forward in tire technology, developing their new TRX range of tires, and the 308 GTBi and 308 GTSi were fitted with the tires 220/55VR390 Michelin TRX
It is worth mentioning that over the years things get changed and it is worth checking that you have 390mm wheels on your car before buying these tires

Ferrari developed the 308 even further by developing the Quatrovalvole or 308 qv with 4 valves per cylinder These cars stuck with the 220/55VR390 TRX Michelin tires- then later cars moved onto 16" wheels
It is worth referencing that when Ferrari did put there 308 GTB qv and 308 GTS qv onto 16" wheels they didn't fit wider tires, they actually fitted thinner front tires. The common thought among people is that bigger is better and so many people with these cars often want to take off there standard wheels and fit wider tires- If this were better Ferrari would have done it.
