idk why everybody says this, in vehicles designed from the factory to be hubcentric, the main load of the car should be on the hubs and the studs should do nothing but keep the wheel on the hub. that’s how it’s designed, and it’s designed like that for a reason.
even if you DO manage to get wheels with the incorrect hub diameter perfectly centered, you’re still putting an improper load on the studs. I’ve used wheels with both a slightly smaller, and a slightly larger hub diameter than the ‘correct’ diameter before, and either way it makes for some nasty side effects. the slightly smaller hub (72.5 instead of 72.56, yes, .6mm too small) resulted in 18/20 broken or cracked wheel bolts. slightly larger hub (74.1mm instead of required 72.56mm) resulted in SEVERE vibrations at several speed ranges, despite proper torquing and re-torquing several times…this is what led to my learning about the whole hubcentric thing.
I know, plenty of people put the wrong hub diameter wheels on hubcentric hubs “all the time” and have “no ill effects”.
Well, plenty of people shoot up heroin every day and don’t die, so maybe i should do that as well? The $10 shipped I pay for a set of centering rings is worth the peace of mind it gives me.
