Turning a fixed tandem axle to a spread axle

Just to give ya a heads up. If you go to a spread axle setup you will go through tires a lot faster then with a standard setup (especially the front axle). At least that has been my experience. If you still want to and can get your axle set up to a spread axle I recommend putting a dump valve on the rear axle. It will help with wear on the tires a little.

 

Do you find using the dump function on the front axle makes the tires last longer on both axels. I have always been curious about this. I just got a trailer last week with a spread and haven't decided what axle to put the dump function on.[/QUOTE]

The dump should be on the rear axle, not the front. And if used religiously it practically eliminates the excess tire wear.

 

Does that apply with a forward spread as well? Also, how do you run it to a switch in the cab?

 

My reefer has a separate pigtail with dumps on both axles.

I want to do a 53' with the spread the whole way at the back, 13' spread.

My current trailer is a 48' with a 10'2" spread.

Pulled open decks since I started grabbing gears, I'm more comfortable with a spread than a closed tandem.

 

Run a toggle switch to a separate pig tail. Do yourself a favor and add at least 2 more toggles and worrying oin the truck side in case you evet want to write I bank up lights/strobes/ whatever.

What do you mean by forward spread? Are you talking about a cali legal on a trailer longer than 48? Doesnt matter. You always want the rear axle to dump, not the front.

 

My rear axle sits forward of the rear of trailer about feet.
What's the purpose of having a dump on each axle?

 

How long is your trailer?
