... No need deflate tires around here...No rock crawling, only mud dirt and sand.
Hey Wainha..
I know everyone has a different perspective on "traction".
Back in '92 I was visiting a 4-wheel drive club in SoCal for first time and on one of their runs in Truck Haven.
There were about 8 other vehicles. We pulled of the highway and I got out to lock hubs and air down.
As I was airing down, I noticed several of the club members staring at me. I looked around and noticed no one was airing down their tires!!??
I thought they were just playing some kind of joke on me. It turned out they were not, and they did NOT air down!!
Not only was I dumbfounded, I was literally without comment during the trail run.
That was the last time I saw that club or any members.
I have been on a good number of runs where at least one wheeler did not air down their tires, and it was obvious watching them trash and bash that either liked it that way, or they just didn't grasp the concept of traction.
In my experience for over 20 years in just about every terrain - airing down my tires was automatic at the beginning of the trail and my normal PSI is 10 lbs.
If there was a run where we had to get back onto a highway for more than a few miles, I aired down to 15.
In mud, snow, and sand - I air down to 5 lbs.
Airing down for me is just physics - more traction. And secondly - less ride discomfort.
Gnarls.
