Tire width; 28 vs. 30 or 32.
My Roubaix came with 28 tires but will fit up to 32 safely. I ride on notoriously bad roads so always looking to improve the ride quality. My old bike (09 Roubaix) had 25's and the new bike is noticeably more comfortable but not sure how much of that is the tires vs. the bike itself.
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.
