    rim not centering on rear tire

    I've just remounted this wheel. It's got a tube in it. I can't seem to get the rim to sit in the middle of the tire. If you look at the side wall you can see what I'm saying. It's definitely not going to balance right. The tube was a bitch to get in there. Maybe the tubes twisted? This happen to anyone? Anyone got any ideas? I've deflated the wheel and tried to reinflate, but I keeps getting out of wack.

    lots of lube, so it slides into place....

      Slowly air it up. Take the valve stem out so it won't hold air, and inflate it, and let the air out, and do it 2 or 3 times. It looks like the tire itself hasn't completely seated on the rim.
      If you have made sure the tube is in there and not pinched it should pop the tire onto the bead. I had to do that with a few bikes over the years. Sometimes you have to give it a bit more air to get them on there.

        Use a ratcheting strap around tire -tighten it and inflate tube

          Agree with the lube comment. How much air pressure you using? It often takes a little extra to get the tire to seat.

            Tried lubing it. Still the same. Maybe needs to setup. I'm going to try the ratchet straps. Got it up to around 40psi and the sidewall looked like it was going to pop out on one side.

              +1....lots of lube. Also, try removing the valve stem from the tube to allow air to enter more quickly. You mention deflating the tire and re-filling but did you break the beads on both sides before re-filling? Try this as well.

              Yes, it can take significant pressure to seat the bead but be CAREFUL doing this. I wouldn't go higher than about 60 psi. If that doesn't seat the beads, break them again, re-lube, and try again. I once worked in a tire store where a co-worker had a trailer tire blow while trying to seat the bead. It was NOT a pretty sight.

              Thanks,

                All good advice above plus is the rim clean and smooth (no rust)?

                  Finally got to to pop over. Just put more air in it. I think the lube helped too.

                  Thanks All
