Q. I need to know the cost factor between starting and stopping 19 times as apposed to starting and stopping 4 times in the same amount of miles.

I am doing a cost analysis on braking a semi - We haul 98,000lb on six axle tractor trailer rigs.

A. There is not enough information to calculate a precise dollar amount, however, you can make a reasonable estimate that your cost of operation performing (19) start/stop cycles VS. (4) would be (19 divided by 4) or 4+ times.

Q. You released Aeris by STEMCO, your Automatic Tire Inflation System (ATIS) two years ago. What makes it different from an engineering and maintenance perspective?

March 17, 2014

A. At STEMCO, we’re wheel end experts, and over the years, we have observed a real problem with wheel ends getting pressurized, seals failing, and lubricants being discharged, due to faulty inflation systems releasing air into the hub. We designed Aeris on the principle of never, ever pressurizing the wheel end.

Q. Does STEMCO make a metric valve stem that is common on Asian and Euro brand trucks?

This metric size refers to a smaller hole in the wheel to fit a smaller valve stem. In searching around the US market, I have been unable to find this dimension or able to gauge how common or standard this size is. Ken-Tool makes a slide hammer valve remover for Domestic wheels we're looking to adapt to fit these international wheels.

A. Yes, Europe uses a smaller size valve stem hole (10mm) with an o-ring seal vs a rubber bushing, same as used in typical North American aluminum wheels (not steel).
