tight wheel centerbore

[Tom239]

My '95 NSX came with (chromed) OEM 7-spoke 16"/17" wheels.
I recently replaced them with earlier OEM 5-spoke 15"/16" wheels.

All model years of NSX wheels have the same centerbore specs,
but for whatever reason these 15" front wheels have a tight fit,
tight enough that it's quite a pain to get the wheels off. The
16" 7-spoke front wheels I have fit easily.

There's a little rust on the hubs where they contact the wheel
centerbores; I tried cleaning that up with emery cloth, but I didn't
remove enough material to make a difference.

What's a good way to improve a tight hub-to-centerbore fit?

Take a wire brush to both the hub and centerbore, then smear on a bit of antiseize compound on the hub contact surface.

could the stock 15 inchers be bent?If you clean up the contact points well enough try finding another local nsxer to lend you a 15 incher to compare.The rust is likely the issue,but the wheel could have issues as well.

The 15s look fine; there's no wobble visible at the lip when I turn
them by hand. And the left and right front wheels fit equally tightly.

About finding local nsxers: I'm in a sparsely populated area.
Sports teams at the high school in town play against teams
from schools as far as 150 miles away. But I do know of
another NSX owner only 50 miles from me.
