    Tire pressure in sand: Too low or too high?

    When I ride in the sand it feels bouncy which I would like to limit if possible. does that mean I need to fill the tire or let some air out. Which tire would affect that bouncy feeling more, front or back? Thanks

    I find bounce comes from the back when pressure is low. I'm 175 lbs and run 5 psi rear and 4 psi front.

    Good thing you asked in the forum first.
    Would have been awful to make the wrong choice

    As we all know the beach is not a consistent surface so you are always either to hard or too soft. You will also find that if your pedalling technique and your gear selection will be a big factor in the pedal bounce , pedal a bigger gear and don't stab the pedals, rather a complete revolution for reduced bounce.

    When you hit a nice stretch of hardpacked sand you could be running 12psi no worries, 3 strokes later there's underlying seaweed and you'll sink.

    Ive found riding on the beach is all about a happy medium that you can put up with, you will soon get fed up deflating and inflating tyres 3-4 times every ride. I even ride the 3km road home with 4-5psi in my tyres after a beachy.

    generally i am riding when the sand is at low tight so it is more of a hard pack and bouncy. Does that mean then that I would want to inflate a little or is it just bouncy because it is sand?

    If you are riding on hardpacked sand, definitely try increasing pressure to find your happy place.

    +1 - you will go crazy if you try to optimize your tire pressure for all conditions. I can adjust pressure a couple times a day if I really think it will be beneficial, but on my trips to Baja I just set it and forget it for weeks at a time.

    For sure the ride on rocks and pavement is not ideal and in really deep loose sand it's harder than it could be, but I can usually vary the sand firmness to match my tire pressure by choosing which part of the beach I ride on. It's way firm by the water [especially if the tide is going out] and really fluffy up high on the beach.

    It's sort of the beach equivalent of finding the right line on a techy dirt trail.
    Safe riding,
