Perfect! That means a 180 is approx 10mm narrower than a 200 which should mean that a 200 is approx 5 mm wider than 190. 5mm = about 1/4 of an inch. Of course THAT means that anyone saying my bike looks stupid because of the "wider" tire is full of shit and being a How you gonna see 1/4 tire difference in a photo?
