No
not at all, while towing a trailer it actually gives better stability and better braking with rear which is estential while towing to settle weight transfer entering twisty stuff especially if going down a Mtn pass, at 47,000km I am about half way thru my second set of rear pads and three quarters thru the original front pads well over 20,000km of that was towing and most of my slowing is done with engine braking before I get to the corner, then a decent jab (if not Towing) of front brakes to correct entry speed.
I have just put a Brigdestone on rear to see if it is as good as some say.... If not it will back to a CarTyre for me. Only have done 200km on it, it feel much better than the Metz ever did on the Mtn but time will tell
