Center Bore Size - What If Its Not Right ?


Recommended Posts

- if this thread really must be moved to maint. or cosmetic please do so Mod.s , thanks

i put this in the performance section because i figured it would get the most input and i figure if the center bore is off i might rip off a wheel or something with hard cornering hahahaha

ok i'm used to cars where there are plenty of wheel options to choose from so i dont know what the difference in center bore will make

so i'm looking at a 5x108 bolt pattern and i BELIEVE the center bore is 67.1

i think that a center bore on a rim that is too small wont fit , but what if its to big ??? wheel options seem pretty limited with our cars so i really want to know what every possible option is - i WANT 18" / 7.5-8" wheels for my s60 - i realize i might have to do some tweaking to keep em from rubbing - but the main question is : can i use rims with a center bore that is larger then 67.1 (or whatever it is) ? thanks guys

if the bore is too big you can buy centering rings to make it the correct size, wont be too bad to drive on wheels that are too big of a center bore. the reason our euro cars use lug bolts and not lug nuts is to help center the wheel better, i have xc90 18" atlantis wheels on my 855 and i didnt run centering rings for a while, i got a vibration at about 65 but it went away and any higher or lower speed. but centering rings are cheap enough just buy them.

i take it the centering rings are basically a washer to bring the center bore down to size ? will ANY difference in center bore do the same thing ? meaning if i found wheels that were 70 CB is that better then 75 CB or are they equally as bad ?

its like a plastic(sometimes metal) ring that goes inside the wheel hub to drop it down to the correct bore size. im not sure about how bad it would be having a bigger bore you really shouldnt even think about it, just take 2 measurements and get some rings. Generally the lugs center the wheels fairly well though.

equally as bad. Anything bigger than the correct size is the same.

i'm not sure i completely understand , are they the same as regular wheel spacer kits ?

like these (for example) - http://www.eurosporttuning.ca/mm5/merchant.mvc?Screen=PROD&Store_Code=EST02&Product_Code=VLS-762-202&Category_Code=VL-S60-su

i see they have a central taper , which i assume is to center the wheel (hubcentric?) , if so , would i be able to use a standard 5mm spacer kit ?

(for a 5x108 obviously)

I'm no expert or anything but the new wheels/tires I just recently bought from Tirerack needed centering rings and clips, which were installed when they got here......obviously the CB is more than what a stock Volvo wheel has but none the less they securely fit over each hub and ride like a dream at highway speeds. :D
