Finally someone who can explain this properly! This has been a huge debate at our company with the mechanics.

Makes perfect sense to me. I wish 100 percent of people could understand this. I’ve been at 115 in my steers and 110 in my drives for years after hearing you explain this on Kevin’s show.

Very good, thanks!

Great video guys I learned a lot about tire pressures for steer and duals . Can you make a video about tire pressures for wide base (super singles) as this too is a weird topic as some manufacturers are saying 80 psi which I think is way too under inflated.

I am running a 1974 International 2070a Fleetstar that I turned into a 5 ton pickup and pull a 14ft dump trailer with it. Max load 29,000 total and my truck only has 1 rear axle. What tire pressures should I run? Essentially it is like deadheadding all the time. I figured decreasing my fronts to 90 lbs and rears to 50-60 was a good idea, after watching this, I am rethinking that. I hardly ever drive over 60 mph.

Is there anyplace that inflation information like this can be gotten in writing?

Has anyone ever told you guys that your knowledge is invaluable? BUT... can I expect to see a gain in mpg running that much over inflated?

I heard you say 1:15 for the stairs but what did you say for the drives?
