I suppose you like the look of a wider tire and that's your main motivation here ?

Because besides of looks, I don't think you would gain anything: more expensive, more weight, slower to turn-in.

You can take a guess by adding 5mm on each side of your current tire and see how a 160 would do. First thing subject to rub would be the chain guard.

Also keep in mind the height ratio. If you just take a wider tire while keeping the same 2nd digit in the size, that means the tire would also be "higher". Ex.: Stock is 150/60 R17, if you put a 160/60 R17 the overall tire diameter would be 12mm more than stock, affecting overall geometry of the bike. Might also come close to rubbing the rear wheel hugger. 160/55 R17 would be closer in height to the stock tire.
