I really only use 1 tire at a time(well 2 technically) so I guess Ill go with what I have since thats what clearly works and I like enough to not swap out.
Panaracer Graveling SS in 43mm.
It rolls fast enough on pavement for me to not be annoyed in the first 6 and last 6 miles of pavement when I ride from my house, and it is wide enough to give me confidence on all unpaved road surfaces I encounter.
My next tire will be a Conti TerraSpeed in 45mm since Ive read it measures narrower, so hopefully the same width as my current tires. The Contis are supposed to roll a bit quicker too.
