i picked up a set of chrome agitators, 19 front, 18 rear, about 9 months ago. the rear tire had a 200/50-18 mounted, while the front had the stock 130. the big difference was that both tires were radials. obviously, they are not stock for the touring bike, but they are stock for a softail. and the rear tires is not the multitread compound so i'm sure that i won't be getting the mileage out of it that the mt tire gets.
i have several misgivings about the tire. since my cvo came with the contrast cut, these wheels ended up on the wife's bike. obviously, i don't want to do anything that would endanger her. i rode the tires for about 6 months, didn't notice any issues (wobble, etc) but am a little nervous after having put them on her bike. not worried so much about the quick wear on these tires as i want to replace them with the stock tires.
