what is the correct pcd and offset plus size of wheels

[badboy]

probably an age old topic but the car we have bought has sh*te after-market wheels so looking for others but need to know correct original steel size for a 1991 watercooled and what size can you go upto 5.5" 6" width 13" 14" 15" inch etc

I don't mean to be rude but did you even bother trying to search? There are literally hundreds of threads on this topic.
PCD = 4x98
Centre Bore = 58.1mm
Offset = Around 35
Can take anything up to 14"x6J with 195/45 tyres
Good options are Cinq, Sei, Uno, Punto etc alloys or even steelies if you're struggling to get original 126 stuff. There is a nice set of 4 spoke 13"x5.5J alloys on FiatForum at the moment in the Classifieds.

The perfect combination is 165/55 R13 over 5,5J13 or 5J13

Optional front 165/55 R13 over 5J13, rear 175/50 R13 over 5,5J13 - mmm, nice...

All 4 175/50 R13 over 5,5J13 beautiful but not on wet...

It's good not to forget the crappy suspension So 165 is good enough and rims as light as possible.

Original 135/80 R12 and 135/70 R13 (for Bis) are 52cm high, so if you don't mind one more cm, you can try some exotic and hard to find sizes:

155/55 R14 over 5J14 - 52,61cm high

165/50 R14 over 5,5J14 - 52,06cm high

165/45 R15 over 5,5J15 - 52,95cm high
