Gravel Tire Pressure Guide

Gravel tire pressure is a compromise between comfort, grip, rolling speed, and rim protection. The useful number changes with rider weight, tire width, setup, surface, and load.

Pressure direction by tire width

35-38 mmFirmer

Mixed road and light gravel usually need more support.

40-45 mmAll-round

The common gravel range for comfort, grip, and speed.

47-50 mmSofter

More useful on rough gravel, light trail, and loaded rides.

LoadedHigher rear

Bags and seated climbing usually push rear pressure up.

Rider weight

Heavier rider-and-bike systems need more casing support. Do not copy another rider's PSI without matching weight and tire size.

Tubeless

Tubeless can run lower than tubes, but too low still causes burping, vague cornering, and rim strikes.

Surface

Smooth hardpack can feel better firmer. Loose stones and washboard usually reward slightly lower pressure.

Gauge repeatability

Use one reliable gauge so 1 PSI changes are real. Pump gauges are often too rough for fine tuning.

How to tune after one ride

Safety checks before riding

Do not use any result above the lower maximum listed by your tire or rim maker. Hookless rims need extra care because pressure and tire-compatibility rules vary by system.
