I currently have 23c tires that need to be replaced and was thinking about trying 25c. I'm a recreationally rider, 6'4" 210lbs, and was wondering if switching from a 23c to a 25c might give me a *noticeably* smoother ride with minimal hit on performance? I've read some previous posts suggesting that big guys might want to try 25's but it seems like most of you ride 23's. Have any of you who are 200lbs+ ridden both and noticed a significant difference between the two sizes?
