<< actually they measure from the outside of one tire to the inside of the
other, then do the reverse and average the two measurements. >>
I guess that this is what I better try to comply with, rather than risk
wasting money on another set of rims and not be able to use them. I would like
thank everyone who responded to my question.
The front of a TR-3 may be able to accommodate zero offset rims, if the front
suspension has not been widen or a TR-4 frame has not been installed. I have
been using one inch spacer plates on the front and am still under the
allowable width. If a TR-4 rear axle housing is installed, the rear track
greater than the allowable width using zero offset rims.
If I remember correctly, Jack Wheeler was using Centerline Wheels with a
three inch offset for his IRS TR-4. He was using only 1/4 inch spacer plates
reach the maximum allowable track.
