The keyword is ST1100 style bikes. Compared to the ST13, FJR, GW, etc., you'll find that very few ST1100 riders have gone to a car tire because you need a GW1500 rim and a custom spacer. AFAIK, there are no CTs that fit the ST11s rim. I ride 20-25k miles/year on my ST11, so long lasting tires are important to me. I run a Michelin Commander II on the rear and get 20-25k miles out of it. I run a BT45 rear tire on the front and get about the same, 20-25k miles/year out of it. The tires are better than I am, so no issued with spirited handling.I have some more wear left on my 98 ST1100 and my plans are to take it to the Darkside with a car tire, I have seen rave reviews from those already using car tires and on ST1100 style bikes and along with more foot print on the pavement you get a longer wear mileage, so safety is important so longer wear, more footprint contact This seems like a changing attitude for the regular riders except those who enjoy the Tail of the Dragon lifestyle.
