The 1-1/4 tires you have are the same breadth as 32, the former being inches and the latter in millimeters. These tires should do fine on any part of the KATY Trail, being in the larger cross-sectional size range. The type of tread can make a difference though. On the trail you don't need knobby tires and they will slow you down. It would be worth changing to a smoother tread in the same 1-1/4 size. I'm not familiar with the trailer you're carrying, but the tire size on it isn't as important as it is on the bicycle, which is carrying the load and providing steering and maneuvering. Have a great ride!
