Bought this trike a couple months back & it has these Metzlers on the rear 210/50ZR17..Only seen car tires on a trikes rear before..I'm new to the trike world & have not been able to ride this yet..Trike has a Lehman conversion that was set up for a paraplegic rider..Just been working on it occasionally to spruce it up & change it back to a more stock type of riding controls & configuration.. Now for the questions > Does anyone run motorcycle tires on their trike rear end?? What are the pros/cons between running car or bike tires on rear?? Should I replace the ME880s before I take it out for a ride?? Anyone?? Thanks
