18 inch wheel question

The front wheels were 1.85, the rear 2.15. This makes sense now as for all this time I thought it was 2.15F and 2.50R. I knew a 120/90 tire never fit or looked right on the rear but they were rated OK on a 2.50 rim. Well *not* rated for use on a 2.15 where I've been fitting them. A KZ400 would have a 2.15x18 rear wheel also I'm betting, so the wheel size is quickly working it's way down. Down from 3.5 to 2.15 currently.

It will probably change next week when the rim shows up. :laugh: I should probably hold off buying a tire uptil I get the rim.. :laugh:
