There are a few in the area that have CT's on their X's. There is one that has a CT but will put a MT next tire change. I have a CT on my Wing and will never go back to a MT. Mileage and handling in the rain is greatly improved for me. I have had no issues for 14,500 miles on my Kumho RF. I will put one on my X once the METZ needs changing.
I use Leal Tires on E. Cesar Chavez to change 'em ($12), they also have a shop at Decker and FM969. Also, many small tire shops will change them for you with no questions asked. I take them off and just take the tires to have them changed. There are also a few in Leander that will change them off of Bus. 183, North of FM1431.
