The difference between 115mm (factory) and 114.3mm is 0.028".
In machinery, that is a huge difference. On the wheels on my car that would be totally unacceptable. Even with hub-centric wheels, I would be concerned with vibration, and if bolt circles don't match the lug nuts won't seat evenly. This could cause galling between the nut and wheel or possible loosening during driving.
This may be a slightly paranoid viewpoint from someone who had wheels come off his car because of (now discontinued) universal-mount wheels.
More than once. Actually, they never came all the way off, I was able to stop quickly enough when they began to vibrate. The lug nuts would slowly work loose during driving.
I also had major problems with some Breyton wheels Discount Tires mounted on my BMW without installing the hub-centric spacer rings. Although the lug nuts were tapered and should have centered the wheels, vibration was terrible no matter how they installed them.
I will never again install wheels on a car that aren't specifically designed to fit THAT car.
I used to care a lot more about getting the best deal. Now I care most about getting the best equipment.
I wonder if anyone else out there watching have had similar problems with non-specific wheels?
