JVS-
That was kind of my point. You're half my age, but you have twice my riding miles. The limits I reach in my riding are defined by my own pucker factor, not the tire traction or lean angle limits. So for me, there's nothing wrong with the tires... until there is.
Despite my conservative riding style, I do know that my riding has changed a lot since I started - it naturally would. At some point, probably gradually and unexpected, I'll gain enough riding time and experience, to do something that I and the bike are fine with, but the tires can't handle. Then I'll know that my riding "skill", or at least confidence, has surpassed the traction of the tires. I'm sure I'll appreciate the feeling of satisfaction at this as, at best, I'm sliding on my ass across the pavement.
Just something to think about, I guess...
