Question for you sled pullers...
I've seen a couple competitions where a dually won, yet it seems like most guys pulling sleds are using SRW trucks. Is there an advantage/disadvantage to hooking with a dually?

id figure more grip in the rear

You might be surprised though. On softer surfaces, like sand, a dually has a big disadvantage. I've never pulled a sled so I'm wondering about the "track"... Is it soft enough where a dually would be a disadvantage?

why the disadvantage? i figured more surface area more grip is it that they have so much grip they dig down. so instead of just pulling there fighting to get out? i jave never pulled before either.

Neither have I, but in places like mud or sand, the dually's have a disadvantage. I know you have more overall surface area in the rear, but it's really two thinner contact points. When the surface is soft, you don't have a large enough contact point to keep the pressure under the tire, and a softer surface will move out from under the tire... either to the outer edge or up between the dualls. With a wider single, you have one contact patch where you can trap the softer surface under the tire and keep on top of it. (one of the reasons you need to air down on sand) Dually tires individually, are typically not as wide as a SRW tire.

thats why i am gettin 2" freds spacers :thumb: more meat for the rear HA HA <-----(nobody get perverted now) but i spose if you ever really wanted to pull with a dually then just take 2 of them really wide rims for 8-lug and slap some good rubber on there with floaters on the front. :confuzeld:just throwin ideas around seein if they stick:confuzeld:

Dave what you have to be careful with is, some organizations only allow dually tires up to a certain size. Then, it might be alittle more fair however there are some places that will let you run as big of a dually tire as you want/can.
I just do not buy it when people say dually do not have a advantage in pulling. Ask any farmer why they put duals on in the spring and take them off in the summer. It all boils down to traction. I also have a hard time buying it because if you watch some of the high hp trucks you will see they are running a conventional rear end on a fleetside truck but add duals. Then, they stick out wayyyy past the box....so the question is, did they buy 2 more wheels, spacers, and 2 more tires because it makes thier truck look good-:t or......

If it wasn't then single rear wheel boys would not be adding duals to a conventional truck...plain and simple:Handshake:
In my honest oppinion I believe it will hurt you in some cases and in others it will help you. Thats why we voted in a rule stating the size max on the dual tire. Would I run duals to sled pull.... NO Do i think on some tracks its worth a few ft. .... YES You have to have some serious power to turn that extra wheel at the same time. I have seen it help the Dodge crew more then the Dmax crew. Gearing???? Wheel Speed????? Trq???? Not sure. but it always seems like the Dodge can carry the trq at the end to turn those tires while the dmax cant. Especially on a short track.

look at how much Paul and I go back and forth. One pull I spank him, next pull he schools me. It depends on the track. Like I tell everyone.... pay attention folks: the rule of thirds, 1/3 of the time duals HELP, 1/3 of the time they HURT, and 1/3 of the time it makes absolutely NO DIFFERENCE!!! Plain and simple.
And the farmers also use duals to prevent compaction and sometimes provide floatation, not always for traction. Pulling tillage equipment in the field with varying soil types, moisture (mud) content, etc. is a different scenario than pulling a sled. It's close, but still different.
I know I hate, hate having the duals on soft spongy tracks where I'm running in SRW ruts. On a good hard, hard biting track - The duals will be an advantage. But like Chad said it's totally different, they don't seem to "spin out" like SRW trucks do.

Almost every 3.0 truck runs dual 35x12.5 tires...It all comes down to having enough power to turn them and enough money to make the driveline last or keep replacing parts...It takes some "serious" power, I think...

Looks like you've been here a little while, but that was your first post so...
:welcome:

Dual 35X12.5's? That's a lot of tire! What would you need for that, a 4" spacer?
