15" x 5.5"

The way most people run it is no more than a 42mm offset on a 205 series tire on a 17" rim.

BUT... it is possible to fully tuck a 19" rim with the perfect offset....I just don't know what that offset is and what tire profile went with it.
You also need to have air ride or you will not be able to turn.....lol

Ok...I have a set of GT rims in my basement right now........

They have 15x5.5 stamped right in the back side of one of the spokes.

So...ummm.....I win :lol:

As for offset......I need to find my tape measure..........
