I rode the bt23 GT, and I'll never get a BT 23 again, too slick on the sides , fine on straightline or big sweepers. If all one does is ride interstates and Highways, should be fine. But in the tight stuff with slick road, the 23 shows its weakness on the sides. Luckily I didnt have to ride in any real inclement cold rainy weather, it was during the summer.
The bt 21 rear, which I like, stands head a shoulders over a BT23 traction wise and cut in wise. But Bridstone was after a life increase, that did happen, but the tire is not as good performance wise from my experience, not even close.
NOw somebody wanted a BT23gt, cause they do 2 up alot, that situation, would probably work well, cause its a Pure tractor tire, stout son on B, worse tire I ever had to mount!
