“We treat shock preload like rocket science, but tire pressure is still just a number we feel looks right.”
The Science of Tire Pressure:
Mastering Grip, Performance, and Safety in Adventure Riding
Tire pressure is not a static number you “set and forget”. It’s a living, breathing variable. Mastering it transforms you from a passenger to a pilot.
Experienced riders “hear” the pressure before they see it on a gauge. They feel it in the bars. A front end that wanders on gravel, a rear that squats too much under power, a tire that skips across sand instead of biting in—these are all physical cues, a language telling you the air isn’t right for the conditions.
Your numbers are your guide, but your feel is what teaches you. Learn to listen. Learn to experiment in 1–2 PSI increments. Keep a log. Over time, that guesswork will become instinct.
Mastering tire pressure isn’t about perfection. It’s about respecting the physics at play. When you understand how that invisible cushion of air shapes grip, comfort, and stability, your confidence grows. The bike becomes an extension of your intent, and you gain the freedom to explore, from desert highways to alpine passes, without hesitation.

I’m reinflating my front tyre for about the 6th time today. I punched a stone through it, plugged it, but it was still leaking. I rode each time from 2.5 bar to 1.1 bar, then stopped to reinflate. The tyre started to delaminate around the plug, so I fitted a new tyre the next day. Luckily, we took tyres along on the accompanying 4WDs. Near Anna Creek, outback South Australia.
