how many kinds of 56.1-73.1 hub centric rings
 

So I am about to my hub centric rings for my 7th gen and now I dunno if there are different kinds of the same sized rings for my civic. DoI have to bring my car/rims to local dealer for them to look at? Or I can just buy from ebay which is cheaper because I already know my size. 56.1mm to 73.1mm (some say 73, some say 73.1 and my rims are exel rh5). I assumed there is only 1 kind of 56.1mm x 73.1mm hub centric rings, it's just either polycarb plastic or alum. please correct me if i'm wrong.

well if you bought the rims thier i would ask them to get the centric rings.....

i know i got mine free from discount tire where i bought my new rims at.....
they looked up the size of the rings for the rim and for the car. and luckely had a set laying around...

nope i bought the rims from a private seller used. so he said he din't have to use hub centric rings and had no problems. i'm thinking maybe it's also my oem lug nuts. their seat is rounded unlike aftermarket rims and aftermarket nuts that are coned seat. i gotta try those tapered or coned seat lug nuts to try to 'lug centrify' the rim.
