#!markdown To get the tires onto the rim, start opposite of the valve and work your way there. Keep the tire in the middle of the bed (more precisely, in the lowest part of the rim), then you should be able to get the tires on without tools. If you get stuck, go around the rim and check that the tire is in the lowest part. Once again start opposite from the valve, and go in both directions at the same time. If it still does not want to jump over, try using your thumbs to push it right at the spot where it is stuck. If you use a tire lever, don't put it where the tire stil has to cross, rather go from the seated part towards the valve. (the valve should always be the last place to go, as the tire can't sit as low as elsewhere) To get the tire seated correctly, put a few PSI into them, and then roll the wheel with some weight on it so that the tire looks like it is completely flat. This will help the tire to "roll" into the seat. If that doesn't help, repeat with a bit more pressure - but don't go overboard, too much pressure will making seating the tire more difficult as it increases friction. Sometimes pulling the tire upwards at the spot where it is stuck also helps. If you don't succeed with all of this, try high pressure, but watch for the max pressure the rim can take.
