Weird Question on Hub Size

[SVTBob]

I’m a newbie so forgive me if this question is silly. I have a pair of Rota Titans in 17 x 8 with what I believe are 73 mm hubs and therefore required concentric hub rings on the ST. (I am away from home and the wheels and the car are there). Since the wheels are seemingly out of production, I’d like to buy another pair to have a full set before they disappear rather than junk them (and I would think I cannot sell just an pair of them). I have found some at various online dealers but most available are 17 x 7.5, not 17 x 8. The ones I’ve found that are 17 x 8 are only available in two hub sizes, 63.3 and 67.1. On the early pages of thisn thread, the hub size of the stock wheels is listed as 63.4. So, it that rounded up ? Would wheels with 63.3 hubs actually fit ? Or do I need to buy a pair of wheels with 67.1 hubs and buy rings to match to get them to fit ?

I would guess that the wheels would fit perfectly, maybe even a little bit tighter than stock. It could be a rounding error and the site has it listed wrong. You could email the company to check the actual wheel hub ID before purchasing. Either way .004" isn't a huge amount. But if you already need rings for the wheels you already have, it wouldn't be too much of a headache to get 2 more spacers. Plus if you're selling them, the larger hubs (with spacers) will fit on a larger variety of cars, more potential buyers.

Thanks for the feedback. I decided to follow your advice and bought 2 more with a 73mm center bore so that they we all the same. Found that the actual is 63.35.

63.4 is the hub size. ... I have Motegi wheels and the rings are 73 mm x 63.4. It took me about a week of checking and double checking to find the correct numbers. .. 63.35 as above is good.
