Heres a silly question - what is the absolute lowest a person can safely air down their tires to? for science!
I think in theory it would handle/ride more like a narrower tire on the street while still offering the huge contact patch when aired down for wheeling. Could in theory help with mpg and wet traction.
Depends on the tire, wheel, vehicle weight, max speed, load while cornering, etc. There's no one answer.
Depends on the tire, the weight of the rig, and the width of the wheel. I've run highway speeds at as low as 17psi but the handling is squirmmy and the steering is heavy. Safely like won't come off the bead when aired down? I'll go as low as 10 psi without beadlocks. I've tried 8 psi but in the rocks you'll find the tires burping air and losing pressure. At that point it's only a matter of time before you lose a bead.
It depends…as others who type with more than two fingers have already said. Here’s an article you might find interesting And maybe a ballpark starting point for your question.
depends on what for. for snow wheeling 2psi can be done with bead locks...I run all week in moab at maybe 14psi and that includes running on the highway between trails..once we are there we air down and don't air back up until we head home..I found the 10% rule is a good rule ie if your psi raises 10% from cold to warmed up you are pretty good...ie if cold 20 psi and you go up to 22 psi after 10-15 minutes running down the road you are probably good..Toyo has a great inflation chart on their website...
whats a bead
holy socks 6 psi lol. and here i get nervous when im less than 35
The bead is the inner edge of the tire (the part that touches the wheel). The beads seat onto the wheel pretty tightly, but are ultimately held there by air pressure. 6 psi is enough to keep it there without force applied trying to push it in. Corner on the street and there's a lot of lateral force on those beads. There's also too much sidewall flex at low psi for driving at speed. That flex creates heat and with enough of it you'll damage the tires.
