have 5 on 41/2 rims the old rims were 21/2 center hole diameter the new ones are 3 inch diameter i have bolt lug instead of lug nuts should the diameter be the same for rims as the axle hub
asked by: Steve
Before choosing a trailer wheel it is important to determine whether your wheels are hub-centric or lug-centric. This is important to know because the wheel will either center itself on the hub or with the wheel bolts.
The easiest way to determine if your wheels are hub-centric or lug-centric is to look at your wheel bolts. If the head of the wheel bolts are coned, then your wheels are lug-centric and the diameter of the center pilot hole on the wheel will just need to be larger than the diameter of the hub. If this is the case then your new wheels with the 3 inch center diameter will work fine on your hubs.
If the head of the wheel bolts are flat, then your wheels are hub-centric and the diameter of the pilot hole on the wheel will need to match the diameter of the hub.
I have attached a photo showing the difference between cone head and flat head wheel bolts.
