What pressure should I run in plus tires?

Most riders find the sweet spot between 12–18 psi, depending on rider weight, terrain, and tire casing. Start at 14 psi front / 15 psi rear for a 75kg rider and adjust from there. Too low (below 10 psi) risks rim damage and tire burping. Too high (above 20 psi) negates the traction and comfort benefits. Use a digital gauge—plus tires are so volume-rich that squeezing them is unreliable for pressure estimation. Front tire can typically run 1–2 psi lower than rear.
