Super single tires vs dually tires

I have run both. The SS never seemed to have lasted as long as duals on my drives. On a trailer, I didn't see any difference other than the weight reduction.

 

I've owned my tractor and trailer about 2.5 years now. Drives are SS. I like them. Fuel economy is my main reason for choosing SS. I average 6.8 mpg in a 2001 Columbia with average speed around 70-72 with 40k average payload. If I slow down to 67 I get 7.3 MPG average. These are actual tank to tank fill calculations. In 2.5 years I have had 2 flats on the SS. Both times I was not rolling so I did not have to drive and did not damage the rims. With my national tire discount I get the Michelin SS for about $800 plus install etc.

When checking air pressure, 4 less tires to check.

 

Some of the biggest & first users of SuperSingles tried them for saving fuel & used low rolling resistance versions. These are especially unsuited to snow & rain. The poor traction isn't inherent in them, it's from the LRR feature.

 

Super singles are where you save on tires but replace rims at every blow out!
Ever hear a super single making turns?
No reason to run them..except stupidity.

 

Duals and their spacing gives water, ice, and snow somewhere to go besides the tire surface.
I've never driven ss and would never pull a trailer with them.
I've watched them going down the road and laugh..pure junk.

 

I hate them. If you're bobtail wet grass will get you stuck.

 

We tried them on two of our pneumatic trucks. We put SS on both the tractor and the trailer. We ran them for about a year.
There was a small tare weight decrease but it didn't amount to much.
The SS didn't give us the longevity that the makers claimed. On a cost-per-mile basis they were more expensive to run than duals.
We ruined three wheels. All three times a tire blew out at freeway speed on a loaded truck and by the time the driver could get to the shoulder the rim was ruined. I don't remember what the rims cost...I've tried to forget that... but they sure weren't cheap. Rims can be hard to find if you need them in a hurry.

 

I live on a dirt road too and never had problems in the mud with duals. I had a loaner once with SS and got stuck. Cost me $300 to get pulled out.

 

I stay with duals.

If you lose one the other will survive if it is a SS that goes, there goes also a whole bunch of money and then some. They don't do well beyond a certain amount of rain or snow and let's not get into ice I never see them on ice.

At one point years ago everyone got into the SS bandwagon. And apparently got back to duals just as fast from where I sit.

I suppose this being America if you want to put a 18 wheeler onto one wheel and one tire big enough to do it there is a way. But Not me. /sarcastic.
