>>2073598>Maybe not but if you go much fatter it's going to feel very sluggish on pavement.Honestly I don't feel this way at all. I ride 35mm road tires and wouldn't have it any other way.
I can turn so much better than when I used to use 28mm tires, and go much faster on turns too.
My ride is so much more comfortable, and a more comfortable ride is a faster ride.
I can ride at lower tire pressures for more comfort on bad roads where I live.
Hasn't impacted my speed much if at all either, rolling resistance is higher yes but it's only a few watts and unless you're like an actual amateur athlete it won't matter at all.
The lowest tire size I'd use now even for a road bike are 32mm, it's just more comfortable especially if you're riding longer distances.
>>2073603A Trek Domane Aluminum was my first road bike ever about a decade ago. I now ride a Domane carbon frame with 35mm tires on it. Just make sure you replace the shitty tires Trek puts on their bike, they are no good and very puncture prone. Get some quality Pirelli cinturato velo / evo and you will basically never get punctures.
