I am a fan of both Michelin and Bridgstone.
I went from stock Michelin to RE11's Back to Michelin. RE11 are quieter, incredibly sticky, fun with a short life span.
Positives: Sticky like nothing else. Almost impossible to get them to slide (when properly warmed up). Surprisingly good in the rain. I thought they were better in the rain than both michelin super sport. Although the sidewalls seem stiff when mounting them, this does not translate into a rough ride. Surprisingly supple for such an aggressive tire. Althought not the quietest tires, again, surprisingly low noise. These tires will have you looking for long sweeping turns just to push them. Seriously fun.
Negatives: The wear. This is no surprise if you understand the rating of 140. Also, on cold mornings, Rubber gets harder and the tires have flat spots for the first mile or so. Vs the micheline super sport, noticeably less rolling efficiancy. This would translate into higher gas costs. However, the demographic after these probably don't care about these last three points.
I was curious as to why Michelin super sport rubber was rated on Tire rack as being stickier than the RE11 but yet, the feeling is the opposit. The RE11 is MUCH more sticky. Then I measured the tire width. RE11 seems to be 3/4 inch wider on the width of the contact surface.
As a summary, if you can afford such a price for a short life, do it. You will not believe how a tire can be so good.
