A bit of a physics question here...
I have been roughly restoring a 1998 Honda 300 4x4. Along the way I am putting a front disc brake kit on it so I am more comfortable with him in our woods and on hills. To do this, you need 12" rims. I found a set with tires I like on marketplace and picked them up. The rears require wheel spacers to make them the same width as stock.
The stock rear rim offset is much further inward (closer to the center of the axle), therefor more of the tire and rim is outside the hub, putting more of the tire and rim mass outside the hub.
The offset on the new itp rims is much further outward (further from the center of the axle), therefor more of the tire and rim is inside the hub, putting more tire and rim mass inside the hub.
The wheel spacers set the itp rims at the same overall width as stock tire width. They are also not any closer to the muffler on the inside of the new tires and rims.
If you include the width of the tires and rims into the overall width of the rear axle, both the stock and itp are the same width including spacers, therefor the furthest point of leverage on the rear axle is the same with both set ups.
Am I wrong in thinking that it doesn't matter where the hubs and rims meet, the overall width of the rear end is what will cause stress on the bearings, axle, etc? The new rims and spacers did not make the rear end any wider.
