Hey I purchased fuel boost 16x8 Black 6x5.5 +20
But the manufacture told
Me that the wheel center bore is 108 and I believe the hummer is 100 if I am correct? So the wheels are little later than the store center bore and it causes vibration at speed which I hate! Anyway to fix this issue or can I get something to cover that extra gap?

Thanks

 

If I got a ring that is 100
To 108 would that work?

 

What did you end up doing? I am having the same issue here - I purchased a preowned with American Racing ATX rims and there is no center ring. They were shaking all over the place on my 350 mile trip home. I am now looking for original rims or the correct rings - did you find any that worked?

 

 

I ordered what I needed on ebay, $5.99 a set (I got an extra set because it was only 6 bucks)and now it is a lot smoother, but still not perfect... and away we go. By the way i have american racing wheels and looking them up I found they were 108mm so I bought 100 to 108 rings and they fit perfectly according to the guy at the tire store that put them on - for free!
