A: This is a very tough question to answer specifically. There are many variables to include vehicle, tire size, terrain and personal preference on airing down to name a few. Some people prefer not to air down while others will air down aggressively. Those that do air down do so to improve traction by increasing the area of surface contact or for ride comfort on bumpy/washboard or uneven roads. I personally have 35-inch tires and air down to approximately 12-15 PSI(pound per square inch). Please keep in mind when going to a lower PSI there is a chance of breaking the bead/seal and ending up with a flat tire. I would recommend having an air compressor with you and check for function before airing down. Hope this helps.
