Your own placard is the authority. You will find it on the printed on the tire sidewall, next to the pressure range. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this bike
Giant fits its own Crosscut Gravel 2 in 700x57c, wire bead and tubeless ready, on 25 mm eX25 rims; the same size appears on the 2023 E+ 1 GTS and the current Explore E+ 1.
The cheaper Explore E+ 3 GTS uses a 700x50c version of the same tire, so the size depends on the trim level, not just the frame.
Giant gives a combined maximum of 150 kg for the Explore E+ 1, and the current model ships with Giant's on-board tire pressure monitoring.

Common questions
- What size tires does the Giant Explore E+ take?
- It runs 57-622. The exact fitment for your bike is on Printed on the tire sidewall, next to the pressure range.
- Can I fit a cheaper tire to a Giant Explore E+?
- Only at 57-622 or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
