Interesting article on tire pressure

[GoldOxide_imp]

Adventure motorcycle sites significantly lower their tire pressures when off roading. 18 psi is not unusual, however, they would be also travelling at much reduced velocities and commonly traversing through mud and river streams - all which serve to minimize tire heating. I am sure if they hit the open road that the tires would heat up quickly and handle dangerously.

Nothing here is profound.

Same thing for vehicles when rock crawling. Most drop their pressure to about 15-20 psi on their tires. This allows the tires to deform more and grip the rocks while also giving them a bigger contact patch. If you are going any distance or speeds over 10 mph though you would typically air back up. Most folks carry a compressor or have an onboard unit installed.
