I fitted up my wheels to our 03 TJ AWD sports and they fit perfect with no rubbing but the centre bore of the new wheels is bigger than the standard wheels. I need to get a set of centre bore locating rings which are apparently available from most tyre shops. Does anyone know the exact center bore size of the standard wheels, I don't have a set of calipers and measured it with a tape measure but I don't think it will be accurate enough? Thanks in advance.

67.1mm.

Worth double checking, but I think most aftermarket rims are 73.1mm.

I fitted these (http://www.ebay.com.au/itm/Hub-Centric-Rings-OD-73-1mm-ID-67-1mm-Mazda-Hyundai-Kia-/180749359921?pt=AU_Car_Parts_Accessories&hash=item2a15805b31) to my 18" Speedy rims and they've worked a treat.

Go there and ask and they should know but try and go to a place that are specialised with mags (ian diffens ect ect) cause they know more about this stuff than anyone else.

Thanks for that super quick reply guys. The wheels that are going on have a 73.1mm centre bore size (the little sticker was still stuck on one of the locating rings that were fitted to our previous car). I measured the standard wheels at a touch over 66mm with a tape measure so wasn't too far off.

I used the same as Red....had plastic ones previously & they can stuff up after several wheel changes.

Had a lot of that at work but its mostly people who don't take the spacer ring off the hub before putting the factory spare on.

Went to tyre shop and they knew exactly what I was after and the size needed (which was the size suggested). They should be there tomorrow. Thanks again for your help.
