Super singles (yes or no)

there is guy ij germany who run 385/65 on all axles with120 9fset rim scania aproved this he say 5% save om fuel

 

also mercedes have miksers with 385 ondrive axles not sure wvich rims i think 135

 

I did a pretty good survey around my place a while ago, theres a few guys who run SS on tandem axle trailer, a few on trucks, but very few on spread axle trailer......... I was in the market of buying a brand new spread axles reefer, but couldn't decide on duals or SS.......... As a matter of fact, i went and see a company few miles down the road from my place, that ran SS on 10foot spread flat bed....... they removed all of them on spread axles trailer, but said they were excellent on trucks and tandem trailer..... I also called the michelin sales rep for my area, had a pretty good discussion for 30 min with the guy..... Michelin doesn't reccomend putting SS on spread axles trailer At all, and doesn't honor the warranty on them if you do...... Personnaly that was enough for me to order the new trailer with Lo-pro 22.5 dually .....

 

What was the reason for removing the SS from all their flatbeds? Did the Michelin rep tell you why they don't recommend running SS on spread axles?

 

I am curious why flatbed outfits like Kiem still use wide based on their trailers. They were one of the first and they still spec wide based on all their trailers. They must know something and have any negative aspects worked out. And all the trailers of theirs I have seen are spread axles.

 

They're monitored electronically, so I'm pretty sure inflation wasn't the issue.

As far as duals in that situation? The 4 trucks sitting in the lot on HOS break had duals, so....

 

Just a thought. Just because there singles don't mean there going to improve your fuel mileage. U have to look at the rolling resistance to what you are taking off and putting on. The lower the number the better for mpg's. I've had the Xone line energy d's on for about 55000 miles. I run central PA 4 hours and back usually 2-3 loads a day. And I didn't get stuck at all this year. Excepted for the time there was ice and used kitty litter to get traction. I had averaged 7.2 for this winter. Home almost every day. The trailers I pull change all the time some have new Goodyear g316 on them and my mileage is very good with them and others have old retreads and mileage goes down. Plus I've check some of these trailers and they only have 75 - 90 psi in them. They only want 90 in them because they say they wear better.
But that's my operation. I like them. And if I was to have my own van trailer or a flat bed spread with a lift axle then I would have the Xone line energy t's on them.

Rolling resistance Xone line energy T is 74
Rolling resistance Xone line energy D is 89
I believe they are the lowest rolling resistance tires and don't forget quality tires you can buy.

 

When those bad boys go, they go big! East out of Fargo, got passed by a side dump with singles on the tractor. He got a good half mile ahead of me when one of them blew. Wasn't aware it was him at the time, but the sound of the explosion reached my truck. I thought I had lost one of my tires.

Huge cloud of dust ahead told me what happened. Whole tread lying in the road, traffic brought to a near stand still.

 

Super singles should be run at 65 mph or below. Such a big tire was not designed to be run at faster speeds as with duals.

 

There is not much input from people who actually made the switch. Has anyone actually seen a significant increase in mpg by switching to super singles?
