You're situation with tires sounds exactly what I experienced. I bought my 2000 GZ250 in December. It had around 2000 miles on it and the tires looked OK, except they were cracking on the sidewalls. I felt it would be wise to go ahead and replace the tires instead of taking chances that one might blow. I bought the Cheng Shin tires and I think they're great! I've put about 300 miles on them so far and I'm very happy with them. They seem to handle well in the curves. I purchased mine from a local bike shop and then had them install the tires. I thought about doing it myself, but it seemed like more trouble than it was worth. The install cost was around $25/tire.
