Hi Team Could i ask for some help clrifying original equipment tyres 348tb & 348tbs 1987 - 1993 215/50R17 front 35psi 255/45R17 Rear 38psi 348GTB, 348GTBS 1993 - 1994 215/50R17 front 35psi 255/45R17 Rear 38psi 348 Spider 1993 - 1995 215/50R17 front 35psi 255/45R17 Rear 34psi In my period fitment guides by tyre manufacturers it lists 17" tyres not 18". However Pirelli do have some 18" tyres that they list as 348 tyres as well as listing the 17" ones 225/40R18 P-Zero front 265/40R18 P-Zero Rear These tyres are also listed as 355 tyres. can you guys clarify what happened? could you specify 18" wheels at the factory gate? If so is there any period data about that such as those window stickers, because i would like to get some tyre pressure dat as well so i can build an accurate web page about the 348. What tyres are best. I'm a big Pirelli fan and they still make the P-Zero, but what are you guys fitting and why?
