What messes up the traction control systems is not the tire width, it's the overall diameter. If the front tire takes 77 inches to roll out and the rear tire takes 85 inches to roll out, now your tires are rotating at two different speeds and the traction control freaks out. So if you want to run staggered, you try to keep the overall diameters very similar. Usually this means jumping three tread width sizes. 215/40-18 (24.77 OD) on the front, 245/35-18 (24.75 OD) on the rear. That kind of thing. 225f/255r is very common; 235f/265r is somewhat common. Or you keep the sizes square and not worry about it.
