Hub Centric rings, what size are my hubs?
 

I'm having trouble finding what size of hub centric rings to get for my 1986 base model. I know the outer size for the ring is 73MM but the inner I'm getting mixed information on...

On Ebay it says 67.1 will fit my car but I'm pretty sure this is WAY too big.. Kal-tire said 59.6 will fit my car because they had a 60.6 or something on there and it was a bit too big. But I just had my mechanic measure the hub and it came out to 59.36...now this measurement could be a little bit off because we couldn't QUITE get the caliper around the studs very easily.

Does anyone know offhand what the stock hub size is? I'm guessing it is probably the 59.6 but I don't want to go ahead and order these rings and find out they don't fit properly. Just want to know 100% for sure. Thanks.

59.6 for sure. Same as 88-92 Mx6 which I also own.

59.6 is right. However, since 99% of us use tapered lugs the rings are completely unneccessary. The clamping friction is what keeps the wheel in place (hence why plastic rings work fine) so rings are just an add on to help things be a hair easier to get lined up in the first place. I just wiggle the wheel on install and I've never had an issue without.

I was reading a HCR manufacturer's website where they claimed that the weight of the wheel could move the wheel/tire eccentricity out of round by 0.002". I bought their rings only to find that the rings themselves were out of round by 0.010".

Now if you run EVO lancer wheels or something with mag style lug nuts, that's a different story all together.

my lugs are tapered yet ive had these wheels balanced and rebalanced and there is still a horrible vibration and ive had every other possible cause ruled out. this is the only thing it could be
