02Tires & rims

Tire size is printed on the sidewall. Rim width is usually on a rim sticker or the wheel maker's spec page.
Pick your tire to set the casing and see its sizes. Not listed? Fill in the fields below.
The number before the dash: 40-622 = 40 mm
Internal (inner) width, not the outer width. Most gravel wheels are 23–25 mm.
Hookless rims have a flat inner edge and often say "hookless" or "TSS". Not sure? Leave it on Hookless: it keeps the pressure under the 5 bar limit.
Reinforced = sidewall protection, e.g. Super Ground, EXO, ProWall, SG2. Not sure? Pick Standard.

Fine-tune after a ride

This is a starting point. Change it in steps of 0.1 bar (about 4%) and ride the same loop again.

↓ Go lower if…
  • it feels harsh or the bike bounces
  • the rear slips on loose climbs
  • you lose grip in loose corners
↑ Go higher if…
  • you feel or hear the rim hit
  • the tire squirms or folds in corners
  • sealant burps out at the rim
  • you carry heavy bags

Method & limits

The numbers land in the middle of six well-known gravel pressure calculators, usually within a few percent. More weight means more pressure. Wider tires and wider rims mean less. Paved roads add pressure, rough trails take some off. The front gets a little less than the rear. Your own adjustment is added last.

A route's surface mix is a best guess. The tool only knows what Komoot, Ride with GPS or OpenStreetMap report, and they don't always agree. OpenStreetMap labels many of its paths as dirt or ground, so the GPX file comes out mostly rough. Komoot calls most of the same paths "unpaved", which counts as loose gravel. For a typical rider that's about 0.35 bar less on the rear via the GPX file than via the Komoot link. Know the route? Set the sliders to what you'd expect.

Use the result as a starting point. On a loop you know, let out 0.1 bar at a time until the tire feels vague in corners or you hit the rim. Then add 0.1 bar back. Check with a good digital gauge: pump gauges are often 0.2–0.3 bar off.

Never go above the maximum printed on your tire or rim. Most hookless rims allow 5 bar (72 psi) at most.
