Probably depends on the bike (year/model)

it's usually best to stick with the stock tire. Unless you plan on going fast in a straight line. then again it does all depend what bike your putting it on.

On my Yamaha 600 I stick to factory size, but on my Honda 929 & 964 I drop the 190 for the 180 width as it gives me better cornering.

Another downfall, of not cornering well, with a larger width can be the rim size might be at the max or possibly width of the swinging arm might be rubbed. Because in some situations if he bike is a 'used' bike he prior owner might have put on a broader tyre so you could be looking at two sizes larger. So check your MOM & if you do not have one, then check with a m/c shop.

Lastly a 160 to a 180 is one 'ell of a change unless you are going for appearance. I had a bike with stock 160 & needing a new rear tyre, but only having a 170 in stock I put on the latter & sold it at a reduced price to a customer once we got in some proper tyres----to go back to the 160.

I read an excellent article on this a few years back in SportRider. Making a big jump like that will not work well with the rim and one side of the tire will bulge on one side. Pretty much mushroom cap.

It's Tire not Tyre. Unless you ride a ducati.
