Large center radius and flat shoulder parts make unwieldy, but bring bearing surface when driving straight ahead and thus mileage (touring tires). Sports tires, on the other hand, have a more pointed contour, which considerably increases the handling.
Even with the tire width, attention should not only be paid to the numbers on the flank, because if you measure it, the tires often turn out very differently. Thus, a 180 / he can only be insignificantly narrower than a 190 / and thus will be in the handling hardly a difference to remember, yes it can even improve if one of a 180 / he touring converts to a 190 / er sports tire. The joy of better handling but tarnished the lower mileage.
