The actual diameter of the two is very close. If the tire markings are exact, 70% of 140mm for sidewall height of the original compared to 60% of 160mm for the Michelin, 98mm sidewall height to 96mm. Total of 4mm difference in diameter or .15". The added width of the 160 makes it appear lower in sidewall height IMO.
