    water in my tires - closed cell foam for erbe ?

    Hi guys,

    As I have major problems with water in my badlands i was looking for some closed cell foam.
    I also want one for my new trencherx ... use desperado for both...
    Anyway, i could not find any closed cell foams for that size of weehls.
    Does anybody use these kind a foams on the erbe ?

    What do you do against water ?

    Thanks

    three 1/8 inch holes around the middle of your tires will keep water from staying in your tires. Nice round holes, not triangles or squares made with a hobby knife. Use a carbide bit in a Dremel or a hole punch.
    It's been fun. See ya.

    By in the middle you mean the inside of the rim or in the middle of the tread?

    Tread... kind of hard to spin water against centrifugal force.
    Whatever it is I just typed... could be wrong.

    hm ... so nobody is using closed cell foam ???
    I mean if the more holes the more water is going in.
    the foam is sucking it up and, as in my case, holding it for month now ...
    are you sure this is the solution ?

    thanks

    i bored the holes out Sunday and ran it for about 10 min and it cleared 95% of the water out. by the time the batts were dead all water was gone. so centrifucal force worked great. Also have not seen any closed cell foam for the 3.8s maybe im looking in the wrong places too.

    Closed cell foam will not prevent water or crud from getting in the tires, it will just not absorb the water but it will still be in the tire. Using centrifugal force with holes in the tire to automatically fling the water and crud out is the simple solution that has proven to work for years. So unless you're an engineer, you will accept this and not complicate things
    It's been fun. See ya.

    Thank you stereodrejeck for the 6 minute video on how to stick a couple pieces of tape to block the holes inside the rims. Remember to replace those holes with the same amount in the tread of your tires or else your truck will bounce on four balloons when landing jumps. The air needs to get out.
    It's been fun. See ya.

    Ha ha ha... Clinical... Anyway I actually used clear scotch tape to tape the holes and it held up pretty well.

    The Bouncyness might be a problem in many cases but I have no problems at all so far. Thanks for your feedback.

    Many people (especially beginners) does have a problem with water in the tires and I just wanna show these people my solution.

    No one has said anything about the longevity of the tires after drilling holes..... Seems like it would work great, but how do the tires hold up??? I'd hate to drill holes to rid water but wouldn't like my tires shredding in return.....

    If the hole was cut cleanly the tires usually go bald before anything else happens.
    If the hole is not cut cleanly, the tire can rip.

    Use an old soldering iron... get it hot and then poke the holes while outside so the fumes don't linger.

    I put my holes in as stated above and have not had any ripping issues. I buddy of mine cut his first set with a drill and bit... they tore. Whether or not the drill bit method was the reason for the tear or not is hard to say... just stating the experiences I have witnessed.

    I also think he twisted up some of the foam within the tire when he was drilling the rubber. After his hole-making procedure the tire was always unbalanced after that.
    Whatever it is I just typed... could be wrong.

    So you leave the rubber in while pushing the soldiering tip through?

    I do not disassemble the tire at all.
