Although I don't have experience with that brand of tire, if they're 3k street miles, I'd ride on them w/o any qualms whatsoever.
Most cases won't be a problem. But, there is a big difference in how some people ride. Some riders are pretty aggressive on the tires, some only lean to a certain angle, and they tires can take a "set" to them. If registered for the school, you have the option to take advantage of the student-only tire deal, pretty good price on tires.
Thanks everyone for their replies. I signed up 6/13 and 6/14 for the level 3 and 4 using the kawis. As much as I want to use my own bike, I figured I'll have to rent a trailer, bring gas, and so on. Sounds a lot of trouble and I'm pretty much going alone. So maybe next time when I retake some of the levels, I'll use my own bike.
DMX: I also have a honda but a 07 600RR. I'll c ya there!
Cobie: Is the 20 dollar fee including putting the tire back to the bike or do I have to do that myself?
