Super Singles on spread flat......

You will get all the advantages of singles on any other trailer. No real difference to spread. If you dont have a dump valve they will wear out quicker just like duals would. Only concern is what psi you fill them to. Duals can carry more weight so if your going to put up to 40,000 on them instead of the normal 34,000 you will need to max out their psi.

 

Why can duals pull more weight? I just wish people would read the 1000 other posts about spread axles and super singles

 

Some folks prefer talking to listening. I never learned anything but my own lack of knowledge by talking.

 

Wide base or super singles perform better at everything than duals.

 

Work great to float on top of snow… thus reducing traction in the winter months. We no longer spec our trucks with singles for that reason.

 

Look at the inflation tables. In most cases 2 thin tires can hold more weight at max psi then one single. That being said, in most cases we don't use the max weight of the tire.

The Michelin X Line Energy T can hold 23,360 pounds per axle at 105 psi.

The X One XTA (super single) Can hold 20,400 pounds per axle at 120 psi.

As you can see at max psi, the single can hold 3,260 less then the dual. Now if your running split axle, your axle weight shouldn't exceed 20,000 pound unless you run illegal and over loaded, so either would be fine. You just have a bit more margin on duals. Now in a split axle config you will have a lot of scrubbing around turns. The X One XTE is designed for high scrub situations. Just make sure you fill to nearly 120 PSI if you are planning on putting 40k on your trailer.

 

Why do you add stuff like this? It just shows that you are a know-it-all that knows nothing at all. A few states give you more than 20k without a permit and A HUGE majority give them to you permitted, including your home state (permitted)

 

My neighbor has it. He is very happy to see 100k miles on a set of tires. He just added a lift axle to minimize scrub and wear on light loads to hopefully give longer tire life.

 

In most cases, you need more axles for more weight. The Op is talking about a 2 axle split and it doesn't sound like he is getting weight permits. In his case he doesnt need over 20k per axle so it makes no difference.
