What I did to my GZ250 today thread

Cathy, have you come across this post?
If a 120/80-16 can work, then a 120/90 should. Worst case, just raise the front fender a little bit.

Modifying the GZ - What's Available?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~

There aren't many tire options for our bike that come in a matching set. There are, however, many options if you don't mind mixing up tire brands and/or going to a slightly smaller tire up front.

The factory tires sizes are: 110/90-16 (F) & 130/90-15 (R)

The rim width for the front wheel is 2.5" and the rear wheel width is 3.0"
That being the case, a size 100/90-16 front tire will work on this bike. It does have an overall diameter decrease of 9mm over the 110/90-16 but that isn't really very drastic.

Samato has verified that alternate tire size 100/90-16 will mount up with no problem.

As well, the 120/80-16 alternate tire size is another choice for the front tire and has been successfully mounted by MRLMD1.
