Thread: Airing down tires for beach driving

    Default Airing down tires for beach driving

    Dipped south side Kenai last year for the first time. White knuckle driving in the soft sand with my heavy diesel truck. Anyone ever lower the psi in their tires to help with the sand? I've heard it helps but I've never tried it.

    Yes. Helps tons. Going down to around 30psi makes a huge difference. Less hopping and chattering. I run my beach trucks at about 20-30psi and highway trucks at about 30-40 depending on loading. If you go under about 20 you risk spinning the tire on the rim and breaking the bead!

    Yes do it, it certainly helps especially if your truck is having a hard time.

    I guess that you need a compressor prior to getting back off of the beach??

    Costco sells a cheap battery jumper/ air compressor for 70bucks, I keep it in the truck all the time.

    I drop my one ton 4WD van tires from 80 psi to 50 psi, makes a huge difference.
    I just drive them at 50 psi to the Tesoro station near Fred Meyer (they have a free air pump that will reach 80 psi).
    without deflation the high pressure tires dig and hop in the sand.
    I have read that some people go down as low as 5 psi if they are stuck and trying to get out.

    I might try 40. Got a compressor today from Amazon and it got my trailer tire from 36 to 50 in no time flat.

    Most tires can air down to 15 without any problems. Especially just running down the beach. We do it all the time in our jeep when off roading. Lower than that you risk spinning a tire or breaking the bead.

    Have to be careful with sharp turns when airing down low?

    Never mind. Did some research and got the answer.
