I’ve got wider rims. In the summer on easy weekend rides I’m good to go out the door with my pump telling me I put 50 in the front and 60 in the back, whether it’s Vittoria Corsas or Conti GP5Ks in 28mm. Below 30F outside and in commuting traffic and I jack it up to 85/100 before heading out- no idea what that measures after ten minutes in the cold.
