I got some 16" rims for free and bought rubber for them only to find the hub is too large to fit the hole. Would a solution to this be to install wheel spacers so the part of the rim that is too small wont even touch the hub?

 

I would take take them to a machine shop and have the hole opened up.

 

What is the difference in the two measurements ?

Is the rubber mounted ?

A lot to be said for test Fitment !

 

Just goes to show that nothing is free. Put the free ones up on CL and use the correct sized wheel. Or...do your homework before you pay good money on a free lunch. (everyone knows there ain't no free lunch)

 

4 wheel rims fits all .
