155 wheels

Hello all!!!
Please, can you put series 2 155 wheels on a series 1? I know they are the same stud pattern, but.......

You canbut the offset would be 9 mm different, I'm unsure of what affest the at would have.
Here you can see a table with the original off-set sizes:

Giulia (4-d) 42 mm
Bertone (63-76) 38 mm
Spider (66-93) 38 mm
AR Berlina 38 mm
Montreal 25 mm
Alfasud Serie 1 45 mm
Alfasud Super 45 mm
Alfasud ti Ser2 39 mm
Alfasud Serie 3 39 mm
Sprint (Sud) 39 mm
Alfetta, all 45 mm
Giulietta, all 45 mm
Alfa 33, all 39 mm
Alfa 75 1.6-2.0 45 mm
Alfa 75 2.5 40 mm
Alfa 75 TS/Turb 30 mm
Alfa 75 3.0 30 mm
Alfa 90 2.0 45 mm
Alfa 90 2.5 40 mm
Alfa 145/146
1.4/1.6/1.7 16V 43 mm
Alfa 145/146
T. Spark/Q/ti 50 mm
Alfa 155, Serie 1
(first model) 50 mm
Alfa 155, Serie 2
(wide aches) 41 mm
Alfa 156 41 mm
Alfa 164 TS/V6 40 mm
Alfa 164 24V 32 mm
Alfa 166 41 mm
Alfetta GT/GTV 45 mm
GTV 2.0 45 mm
GTV6 2.5 40 mm
Spider T.S./V6 35 mm
Spider V6 24V 31 mm
GTV T. Spark 35 mm
GTV V6 24V 31 mm

But then there is the additional thing about bolt circle.

Old Alfas have 4x108 mm.
Alfasud/33/75/90/145/146 have 4x98 mm
Big engine (TS, Turbo, V6) 75/90 have 5x98 mm
147/156 have 5x98 mm
166 has 5x108 mm

The center hole has a diameter of 58,6 mm, but from the starting of the Fiat aera (1987) this size changed on new models to 58,1 mm.

If you find a new wheel which fits on a new Alfa, and you would like to use it on your Alfa 33, then you have to enlarge the center hole by 0,5 mm.

2x 145, 4x 75, 4x Sprints,a 156, 146 now a 155

Thanks for that. I am wondering which way the offset is - in or out, and can you space the wheels with a spacer

Nice one Toad! Where did you get that list from? Don't want to picky but i do know a couple of them are wrong though.
155 16" black speedlines are 40mm
155 15" wide body are 37.5mm and will fit an 8V even with 205 tyres (if you trim the plastic bits on the doors a little bit)I know, because i did it before i fitted the 17" rims on my 8V.
The greater the offset, the more the wheel goes inwards. Hope that helps.

Some of the different wheel style's had different offset's, so that explain's some of the mistakes.
I found the list on a 33 site.
Oliver, Spacers should be ok if they a good ones.

Hi all.
OK, it seems as if the BLACK 5 spoke 'Q4' type wheels are not the correct offset for the series 1 cars. (I don't know about the charcoal coloured wheels from the series 2s.) Is this a correct assumption? Is there a 'correct' offset that must be used or is there a tollerance that is acceptable. Presently I have 15" wheels (Alfa) and 205 tyres. I don't know what the offset on these is.
This is an ongoing curiosity
