Hub Centric Rings
I initially installed the new Cragar Soft 8 wheels straight onto the X5 to see if I really needed hub centric rings. Hub centric rings are designed to fill in the gap between the hub of the car and the center bore of the wheel. Most aftermarket wheel manufacturers design their wheels with a centerbore large enough to fit a wide variety of cars. These wheels have a larger center bore diameter than the hubs of most the vehicles they are made to fit onto. As such, the wheels are mounted "lug centric" as the wheel lugs are the only thing keeping the wheel centered on the hub whereas stock BMW wheels will always have a very close fit between the center bore of the wheel and the diameter of the hub to more accurately center the wheel. The concern is that a lug centric installation can result in wheel vibration because the wheel is not accurately centered on the hub. Which is exactly what I found. With the lug centric installation, I would feel a vibration most pronounced at around 50-60mph. It felt exactly like a wheel out of balance. Then I installed a set of hub centric rings to fill the gap between the wheel and the hub. This provided a very snug fit and centered the wheel to the hub. The result was that the vibration disappeared and the wheels/tires drove perfectly. Hub centric rings come in sizes to meet almost every application. In the my case, I needed rings with a outer diameter of 83.82mm to fit the wheel and an inner diameter of 72.5mm to fit the X5 hub. I was able to order a set in this size from Amazon at a cost of less than $10. The rings are constructed of a very hard plastic material. Installation is easy, they simply install over the hub and the wheel goes outside of that. Here is a pic of the hub centric rings installed: |

I got some 285/75/18 General Grabbers installed yesterday. Very tight in the back so put on a small slip on spacer. Will check the turning clearance in the front!

To get wheels to work without hubcentric rings, you have to have wheels made for either conical or sleeved lug nuts/bolts. Flat lug bolts or nuts won't center the wheel with the adequate tolerance to avoid vibration. It looks like your wheels aren't made to work in a lugcentric installation at all.

I’ve told my wife that I’m keeping my E53 forever so that I can lift it and put mudders on it when I finally get my E70 5.0i

* First Trip *
Took a trip from LA to visit a friend in Northern Arizona for a 5 days. We did about 1,200 miles total with around 50 of those miles off road on primary and secondary forest roads. Nothing too difficult. The X5 ran great cruising at 80mph on the freeway with the temp gauge normal even in 105F temps while crossing the California and Arizona deserts. The General Grabber ATX's drive perfectly straight and are as quiet as a street tire on the freeway. The freeway ride is very nice without any bumping or jarring (my sports cars ride harsher than the X5 with the all-terrain tires). We spent most of one day driving the X5 on Forest Road 300 which follows the edge of the Mongolian Rim for about 20 miles. We had lunch at one of the many campsites. The views are absolutely beautiful. Off road, the X5 worked fantastic but the front tires did rub on the fender wells when I hit large bumps. I have a 1.5" lift ready to install as soon as I get some time. Otherwise, the X5 performed perfectly on the forest roads. The only problem that arose was when the passenger rear window got stuck in the down position. We simply removed the door panel and used a wood stake to prop the window up for a quiet and cool drive home. When I got home, I replaced the window motor and slide mechanism and it works great. |
