I just had a nightmare experience. 175/65/14 barum tires, installed on a spare set of 3spoke rims, so I had the 6 spokes and original shaky kendas as backup. Everything seemed fine going on, but 1/2 mile into the test ride all heck broke loose. All kinds of warnings, and locked into first gear. After getting home, it wouldn’t even go into first. Massive fender support rubbing, to the point of eating the wiring and shorting it out. After fixing the light wires and replacing the fuse, all is well, all alarms off, moves fine, on the original tires.
Lots of shim would be required to make this work, which made no sense. So, on a whim, I measured the wheel backspacing. Both sets of rims are 14x5, but the 3 spoke wheel has 1/2 inch more backspace! To the outside of the rim, the 6 spoke wheels are 3 5/8” backspace. The 3 spoke wheels are 4 1/8-4 1/2” backspace.
Now I see the problem! I picked up the 3 spoke wheels cheap, never imagined they would be a different offset.
