Will these work?

Post by bigbadbob » Thu Jan 30, 2014 1:43 pm

Much that I'd love a set of the year one deep dish rally IIs, I haven't that sort of money. But I've got a set of 5 spoke revolution alloys which came as spares with my car when I bought it - I was told they should fit my 1980 Trans am. Stud pattern looks about right.

Using a ruler they measure 16" across the front face (inner face seems slightly smaller?) edge to edge.
Width edge to edge looks just about 8 and 3/4".

Does that make them 15" or 16" rims? and 8.5" or 9" width?

I've no idea how to measure if the offset (distance from hub to outer rim?) is correct. Anyone know?

Also, if I was to use these apart from needing a bit of a refurb, I'd need to get some of those long revolution wheel nuts - so what length, width, thread would I need to look for?

Or... should I just flog them and stick to the snowflakes?

it is the inside edge, where the tyre bead rests that you measure to give tyre diameter
as for offsets and pattern Im sure Jon will be on later and will know the correct offset etc.

they sound like 15x8 , to measure the back space put a straight edge across the inner face and then measure how deep it is to the hub.
i run that size with a 4" back space all round
