Rolling Resistance

I'd say 20,000lbs.

Thanks for the rest of the info everybody.

 

It depends on the state your in...

 

I worked at a trucking company for a few years and the tire man one day came with me on a road test and we went to this remote area, and he had me drive at 60 KM an hour, to the top of this little hill and then take it out of gear and just coast. He did that for every time he changed tires to see if they were a matched set he knew how many telephone pole we passed before it stopped. I did it from then on to check units for low power and after a lot of repairs to be sure there was not something dragging. We ran Michelin tires, buying only new fronts, and recapped them when worn.

 

I was thinking of doing just this .. IF I decide to try some Micro Blue wheel bearings. Just out of curiosity.

 

That's a good idea, it couldn't hurt and is a valid test

 

The nice thing about it if you are an owner operator, is if you find a good spot near where you park you can do it when you come back from a trip and it will tell you if there is a problem.

 

I know it would depend on the tires, but would a tractor with dual aluminum wheels have less rolling resistance/better MPG than a tractor with steel wheels on the inside and aluminum on the outside????

 

20,000 providing your tires and wheels are rated for that kind of weight
