A 160-80x16 is the widest, without having to replace a sprocket or gain clearence any other way for the belt. Metzlers are just a tad taller then Dunlops, for reference, even though the same printed size.
Metzlers are wider then Dunlops, and Avons run wider then the Metzlers, in my experince.
Even at that......the 3" wide rear rim of the sporty is barely wide enough for a 150mm rear tire, let alone pinching a 160 onto it, for appearence only. You begin to lose contact area due to the crowning of the tire, "making" it fit on a rim that's too narrow.
