SRW vs DRW driving in sand.

I camped at Pismo a couple of week ago with my SRW Ram towing a 21' TH.
I aired all tires down to 20 psi and had no problems.
I noticed numerous DRW also pulling trailers seemed to be doing ok.
I know the idea is to spread the weight as much as possible and a DRW would provide a much wider footprint.
Besides the tires rubbing against each other does a dually do better in the sand when aired down?

  • It depends on the width of tires and the air pressure. Some SRW trucks have tires the same width as DRW trucks. Other SRW trucks have wider tires.
  • Yep they suck. While duallies may have a larger contact patch on paper the reality is two smaller contact patches are worse than a single larger contact pad you get with SRW.
  • Duallys suck in the sand. I really gotta keep my speed up or I bury myself.
  • Duallies have a disadvantage that the outer rears are pushing more sand. SRW trucks only have to push sand with the front end, then the rear has a nice compacted track to follow.

    And X2 on M/T tires being terrible with sand. I watched two identical Dodge Rams do a hill climb at the dunes one day. The one with M/Ts and lockers couldn't make it to the top. The other dodge had A/Ts, and only factory limited slip, and still made it to the top without even spinning its tires.

    Look at the cement trucks in areas with sand... running super singles that can be aired down. A smooth tread will go better than a mud tread in sand because it does not dig you into a hole as fast.

    Dually 's are the worse in sand, your lucky cause you aired down so much, and you did all the rears. Depends on tire you run also.

    Pin it to win it, pismo has blow fine grain sand, that will get ya, has me before. If I'm in the groove I can tow no problem in the deeper sand and I make myself proud.

    You did great!!!
  • The duallies generally are worse off than the SRW's. Not that you shouldn't bring one out there, because plenty of people do. Just depends on what the sand conditions are and what you're pulling. Sometimes everything is getting stuck no matter what and sometimes 2WD cars are driving all over the place.
