Haven't been on much in a while, too much going on. Just in case anyone else is interested, here is my T30 review. I included Pictures of my front and rear Bridgestone 023s with @9k on them. Keep in mind these have 1 OKC trip as well as some Va./ WVa. runs (mostly slab though). I also included a pre-mount picture and a post trip picture of the T30s. There is a rather pronounced visual difference between the two compounds. I never noticed any difference in feel transitioning from 1 compound to the other. After @900 miles on the T30s, I am not disappointed with the tires. It is a bit hard for me making a comparison going from a worn out set to a new set. The carcass feels pretty stiff on the T30s, even from what I remember about the 021 & 023. Temps ranged from @75-87 degrees and warm up times felt fairly quick. Even a quick 5 mile run from my hotel to the gas station yielded some good heat. Tire pressures were 36 front, 38 rear cold. After getting used to the new profile and stiff carcass, feel was very stable and communicative. I never felt any tendency for the bike to want to just fall into a turn. They held a line well and were no trouble to change lines mid corner when needed. Over all, I feel that these tires are every bit as good as I expected. The real test will be in how well they do toward the end of their life, but, as new I felt they were a great match for my mixed mountain/freeway riding. The 023s really fell off in traction toward the end.
