I just bought a ASA JH8 19x9 and 19x8 from the Z and I installed to my 8 but they recommanded me to buy a Center Hub cause the center ring of that rims is too big or something is that True??? need help please

 

Not necessary but some people recommend them.

 

yea but whhen i jack my car up, put the rim on, lugs and tight up everything then i spin the wheel by hand n it squirling and when i look at center hub...the center on the rim is bigger than in the car..it not fit perfectly

 

What is squirling? Almost all aftermarket rims have a bigger hub than on the rx8. It is so that the wheels will fit on more cars. The people didn't tell you to buy a center hub, they told you to get hub rings (preferably metal) that go inside the wheels hub to fill in the difference. I don't have any on my wheels and I haven't had a problem, though I'm sure someone out there had vibrations or something.

 

bcuz when i put them in n spin they not roll straight....so u dont have a hub ring on ur?

 

I don't have hub rings on mine.

 

hubcentric ring would be a good idea.
I have them on my Advans.

 

If you torque the wheels correctly they are not needed...

 

I use the hub rings because they are pretty

 

i'm sure others know better, but from pers experience i would recommend them. my gf's mazda 3 had aftermarket wheels when we bought it, everything was fine until we hit 65mph...major vibration in the steering wheel. ended up getting oem wheels for her car, and when the peeps were mounting them, they found 3 wheels with hub rings and one (in the front) without a ring...like whoever installed them missed one or something! i can't say that IS what caused the vibration, but w/ the oem wheels we don't have it anymore, so, take that for whatever it's worth i guess...

 

correct: having the rings will help against vibration.

 

yea thanks for sharing opinion....that help me a lot i already order the hub rings it should be come in Wednesday....i hope they gave me the exact size

 

lets hope so.
if not, many tire installation companies can help you figure out the size and order them for you. (then just return the ones you already bought if they are the wrong size)

 

oh i got those of from the Z...
