Mega Carriers Vs. Lease Operator; Tread Life Management

Rob D., Prime recommends the proper tire pressure for the tractor is 110 psi on the steers but 100 psi on the drives. I believe the difference is due to the drives being super singles.

And yes, Prime does splurge on their equipment & replacement parts. But not all megas are built the same. At the same time, not all "innovations" deliver on their implied cost benefit. Two examples come to mind, those wheel covers that hid the axle hub seals & those trailer tails. They do try & that's why I'm back with Prime.

That said, all the safety equipment in the world cannot correct stupid or ignorance! What I've learned in the few years of driving is that the way drivers are trained creates both great drivers & dangerously misinformed drivers too.

Example, I noticed a driver pull his brakes while he was on the scale. I went over & politely told his that by him pulling his brakes, his weights will be off. He looked at me like I was crazy & said that's the way he's always done it. I responded by letting him know that he's been very lucky cause that's not the proper way to scale a load & walked away.

I thought just pulling the tractor brake is the proper way to scale? If you sit with your foot on the brake then all of your axles and steers are locked up.

Don't set your brakes when your on a scale. New air ride suspension and some trailers with the anti dock walk WILL bind up a multi platform scale and give bad axle weights, (maybe not so much on a single platform scale) Setting brakes on a scale usually causes heavy steer weights and lite drive weights. When you set your brakes it dumps the air bags, but the brakes set faster than the air being released, so the truck wants to settle but with the brakes set it binds up the suspension also binding up a scale. Truck scales as big and well built as they are are still very sensitive to movement and need to move freely. bound up suspension wont let the scale find its center once the movement settles. Hope I'm making sense here. Older trucks and trailers with spring suspension usually wont cause a problem. If you have to set your brakes, set the trailer brakes only! or turn off your truck and put it in gear. So, next time your fighting your weights, sliding 5th wheel and moving tandems , ask yourself, Did I set my brakes on that scale??

What I posted before was from another website. Let me explain it this way.

You don't pull the brakes or sit on your brakes. You sit there in neutral without using your brakes at all. Every single scale I've pulled onto has been level, except one, the CAT scale in the Atlanta Petro. I went next door to the Blue Beacon & that one was level.
