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?
You are absolutely right-Though It is dependant on how critical the tolerances are on a given part, or piece of machinery. It two lug nuts are exactly adjacent from each other, that translates to about 14 thousandths of an inch, that the lug nut will be off center towards the edge of the rim.
I can't speak for the wheels and your experience with them because I don't know the difference in their tolerances and dimentions. One reason had to be the lack of hub centric rings. The nuts may have initially centered the rim, but your lug nuts probably loosened more to the fact that the lug nuts and studs were also serving as a load bearing assembly for the wheel. That is the hub's job, and the hubs job alone. the lugs and studs are there to keep the wheel in place laterally, as their designed for tensile strength and not made to withstand the sheering forces from the weight of the vehicle and they will loosen with absolute certainty eventually if made to carry the vehicle's weight and forces.
You felt the vibration, because as soon as the nuts were loose enough, your wheel became de-centered, which would not be the case if the wheel's center bore was mated perfectly with the hub, even via a hubcentric ring or hubcentric spacer.
All being said, yes proper wheels should always be used for a particular application. Can you get away with 114.3 on LX vehicles? I don't know,some seem to have, but Personally I would avoid it, as I want to cruise at over 100mph with confidence, and not be thinking "what if"?
I'm in complete agreement with you and I may have been misunderstood in my previous post.- I would never recommend mounting an aftermarket wheel on a vehicle, unless it's fitment was within proper specs. Our safety rides on our wheels as they are the only contact point between the car and the road.
