Air pressure singles vs duals

[Sledheadxp800r]

Just went to duals on my puller and I'm looking for any input on rear tire pressures.

 

[slipclutchms]

twice the tire....half the pressure.

I would try 30psi or so pending track on the rears

 

[Sledheadxp800r]

I ran way less than 60psi in the rear with singles

I would also like to hear some input, but this is super secret sled puller stuff also...

I tried less than singles and truck always bit hard and loaded an unloaded causing hop issues, that being said we air up to give up some bite and maintain hitch height. Not sure if we are right or wrong

Depends on the track with my sts duals. I run as high as 40 psi on the real tight clay tracks and as low as 20psi on sandy tracks.

Looks SICK !!!!:thumb::thumb: How Wide Are The Back Rims ?

 

[Sledheadxp800r]

The front wheels are 10s
The outer rear wheels are 8s
The inner rear wheels are 6 1/2s I think. They're off an 07 GM dually.

I'm not running any rear brakes or leaf springs so I was able to mount the inner dually wheel with no spacer. The outer wheels have 2" backspacing I needed a 4 1/2" spacer between them but made a 4" spacer work

I'd like some psi numbers from tight track guys. I run 40 in both rears but it's only my 2nd time hooking with duallys

 

[chevytuf01]

Gotcha we have to run rear brakes ... ill have to see what i can come up with this winter ... im gonna run duratracs like Rich on the other woman

[DieselmafiaLLY]

Thats a pretty safe place to start. If you fine they are hooking too hard and pulling you off the charger add some more air.

 

[Sledheadxp800r]

I have 25 psi in mine

I usually ran about 35 in the rear with singles

 

[CurtisEmery]

if it works go with it. i very rarely run more than 30psi out back.

I've never pulled with duals before so I have no idea what to run
