Do you like Super Singles or Dually tires better ?

I think it all depends on how good your set up is.
If you have a TPMS then i don't see a issue with singles.
@Korodoch mentioned the 6x2 setup.
Lousy if you can not lift or deflate the dead axle.
Great if it is done the right way.

 

prime is mega bean counters they are the worst in all of the megas for counting beans

 

great point but lets be honest any mega driver wont want to get his flippers dirty

 

I've only driven one truck with super singles, that was the Mack demo I drove last year. Hated it, they felt squirrely to me, in three days of driving the truck, never really got comfortable with them

 

I don't mind wide singles. Softer ride but mushy. Like riding on marshmallows. Better traction on hard ice but worse in slush or standing water.

Wides usually have a narrower stance then duals unless you run offset rims or spec the truck with a wider axle to run singles. Offset rims put more stress on the axle bearings and nobody wants to spec the wider axle as duals are still popular. Easier truck resale.

If you need to throw chains on the highway then duals are nice. You can just chain the outside tires with a single chain and go. With wides you need to throw a double set on each drive axle. Four doubles VS four singles, or even two singles on one axle for duals. With wides they want you to chain both axles no matter what. If you need chains at all, you need to chain both drive axles when running wides. Can't just throw a set of single chains on one axle like duals. Well you can, and it's practically enough, but it isn't "legal"...

 

I tried that single chain an drives once, friggin worthless, especially if you are empty. I will occasionally if in a hurry throw on a set of three railers only on one corner to get me to the top of the hill, but I don't like making a practice of it, as it is hard on the rear. I do carry one single, to throw one on a steer if I need it, but that is very rare.

 

There's pro's and con's with anything out there. I've driven both set ups and there are some real advantages to singles if used on a certain trucks. You look at most of the west coast gasoline haulers and you'll see the singles. That's because they are lighter (more gallons), they lower the center of gravity which means less roll overs, and the cost. However, they are a tire I would not want to leave town on. If you have a flat there's no more running on the other tire to get it fixed. You're stuck where it blows. Plus you have to look at the availability of the tire when you need to replace it. Not all that many companies are running singles so the tire companies just do not stock them. BTW, I've had blow out with the singles and I just pulled the truck over. There's no greater danger with the singles going flat.

 

How can they both be lighter AND lower the center of gravity? Are they just overall shorter?

 

They tell me it's wider. Your see almost all of the gasoline companies out west using them.because of the rollover reduction.

 

Prime is all about fuel economy, but they also run lightweight trucks, trailers, etc for being able to haul weight. Used to frequently haul 47XXX loads for General Mills.

Super singles are bad for traction. My wife jackknifed last year, and I'm positive those tires were partially responsible (she was going 50 in a 75 in moderate rain, empty trailer). The larger culprit is the ###### pavement Texas has been using lately because it lasts longer, but it does not absorb water and creates some seriously slick roads. There's a spot near my house where at least three trucks have jackknifed in rain, also where my wife did. See pickups get squirrelly there all the time too.

Oh yeah, wide based tires. They are bad at traction on mud, ice, and rain. Pain in the butt to chain too. If I was buying my own truck, I personally would avoid.
