I'm going to need tires soon and considering going wider. Is there a noticeable difference in ride quality between 28 and 30 or 32? And will I pay a price in rolling resistance going wider? My main use of the bike is rides in the 70-100 mile range on the weekends. Speed is not important but I don't want to feel like I've ridden an extra 10 miles at the end of a ride. Currently riding GP5000 TT but open to other suggestions as long as it's something that isn't super easy to puncture.
