I have put about 9,000 miles on a set of 205/55/16 T1s on my stock rims. When these wear out, I will replace them with the same.
The car went from vague and soft steering to an alomost razor-sharp kind of response. The tires stick beautifully and do well in the rain. They are horrible in the snow - downright dangerous. I have started to notice some inner tread wear on the fronts and will do a front to rear swap this weekend. That is probably from more aggressive cornering - prompted by the tires' abilities.
On a side note, I drove a WRX this week with the 16" wheels - the handling seemed crappy with the stock tires. Is the car an improvement of the RS -sure. But getting back into my RS with the T1s showed the huge improvement these tires make. When gently nudged, the WRX seemed to easily overpower the abilities of the stock donuts.
