tire size help... not gs

[Lulu7404]

Did a search on tire size, and got nothing.
I picked up an 07 CB250 for my wife to build her skills on while I build up her GS650G. I am pretty sure the tires are original w/ 7k miles, I would feel better on some new ones. The front is giving me some trouble. It is sized 90/100 18. Any older smaller displacement GS's use that size and found another size that works? Rim size is 18 x 1.85 if that helps. Can I go to 100/100 safely? The original tire was a Bridgestone K300, and doesn't seem to be available, it was hideous anyway.

Thanks in advance.

I believe the right size is a 3.0*18 for a 1.85 wheel.
There is a good guide to tire sizes near the end of the Conti guide you can download here: http://www.conti-online.com/generato...manual_fr.html
