Pro's and Con's of Super Singles

Some of the local gas buggies have them now. Eagle Transport has them. They also went to single screw and tag axles. I know 1 truck jack knifed 2 days ago damaged itself truck and trailer+paid for a tow. They grounded the fleet and lost revenue. Granted it was a record storm. There'll be more.

 

my pal was sayin, 110 pounds of rolling resistance for each dual, 160 for one super, so less weight/less resistance, a little better fuel mpg

Im on them all the time now in the mud and hills of coppermines...I can say they are 5000% better in the slippery mud, we are all in single screws as well!!!...The duallys get stuck so easy, the extra wideness of the super makes a ton of difference....

Another interesting tidbit, our barn has 100 trucks on supers all the way around, not one blowout yet, lots of flats, but no blowouts!! In 2 years!!!!!
Im thinking luck, but who knows!!

I hear they are recapping now, so , this will get interesting...

 

I had a blew out once and just called the shop. No big thing with me but could be if you're way out in nowhere. They seem to stop better and realize we've been running these things sent the early 1990. Here how the company makes. The axles are wilder but not by much. Maybe 6" but that's about it. That will bring the CG down so that means less rollover, and less product loss, and less money spend out. With the extra shavings in weight each truck the truck can safe up to a figure like this: with the singles the truck would load an extra gallon. If gas was a 1:00 that would mean that truck alone would save $6 a shift Make it $12 for the night shift running too. Now if we have another 3 trucks you could add $48 dollars a day in just buying the type of tires.

 

Your wrong...flat out wrong...they save fuel!!

 

Now if one were to convert over to SS's from duals, do you need to change hubs as well? I've heard that SS's wear out wheel bearings faster. Also will they narrow the overall width of the axle from either 96" or 102"?

 

If they are mounted on a 0" off set it will measure 96" across. What the large majority of carriers do is mount them on 2" off set wheels to maintain the 102" profile. I have heard about the wheel bearing and wheel seal issue but it doesn't seem to happen to everyone. Mine are mounted on 2" offset wheels. I have heard you can have a "marriage bracket" installed adding additional support to ensure the issue does not come up.

 

With a 0" offset, the track will be slightly narrower but it will put no additional load on the wheel bearings. You can always put these on with no mechanical problems.

With a 2" offset wheel, the track remains the same but it does put more torque on the axle. Some axles can handle it, others can't.

 

I'm a company driver so could care less, but this is what I know. I F up a LOT of tires! I drive a flatbed and wind up on a LOT of construction sites and off road drops. I see the invoices every time I leave the tire shop getting patched, recapped and replaced. I can only imagine the costs of those things. The whole idea of better pressure is fine, but you can put that hose across the dual tires to equalize them and same thing accomplished.

 

Today's singles are way tougher than the past

Good year is lining the inside with a gel that seals up punctures. I use liquitube and any nails or screws I just leave in. Most of the time with good tread the nail or screw doesn't even get past the plys

Michelin says they put 1/4 of street in the tire!

Almost like having solid tires

 

Is there a way to prevent the wheel from getting damaged during a blowout? Did you have PSI sensors on your tires? What was the increase in MPG? 6.5 to 6.8?
