tire change

What on earth should I do to make a new tire pop in the bead all around the rim when inflating it.

I have now changed 5 tires within the last 1.5 years and none of them has seated without a problem. I am using liquid soap on the beads, but every time I have had to pound the tire with a rubber mallet and what not to make the beads to seat. Perhaps I am too slow and the soap dries up and instead of being slippery is tacky. How much air pressure do I dare to to use?

I used "pledge" when I changed mine. Just sprayed it liberally on the tire and rim and rubbed it in. The bead set just fine.

spray silicone works well too just dont be tempted to use any of the tire pastes they are too slick and take days to absorb i have actually seen the rim spin inside the tire after using the paste.

1. Take a length of rope longer than the circumference of the tire and tie a loop in one end.

2. Lay the rope down the middle of the tread and run the free end of the rope through the loop.

3. Pull on the free end of the rope to compress the tire and push the bead toward the rim.

4. Tie a quick release knot in the rope to hold tension on the tire.

5. Turn the rim vertical.

6. Add air to the tire, and where you have leaks, turn that portion of the tire towards the ground and apply a little pressure.

Hope this helps.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Thank you all for the advice. Leaks are not the problem, it just won't fully seat all the way around. I think I will need to find a better lubricant for the job.

Are you talking about a trademark like in a furniture wax?

I've done that mentally, but do I have to do it aloud?

Once the tire is completely on the rim, I just spray the beads good with Windex. They seat perfectly every time. Anything slippery will work, but I would avoid petroleum based products. They will deteriorate rubber over time. I have used STP Son of a Gun to mount tires with,(damn that stuff is slippery) but still use Windex to seat the beads. Make sure the tire is not touching the ground or floor. Either support the wheel by the axle, or lay it on it's side, so the tire is not touching anything.


If you can't get the bead to seal well enough to hold air, I use a variation of flitecontrol's procedure, which I have never had to use on motorcycle tires, but it works great on car and ATV tires. Instead or rope around the tire, I use a ratchet tie down, like I use to tie down my dirt bike with. You can put a LOT of pressure on the tire tread with one of those, forcing the bead against the rim. Jerry.

This is a long shot, but I have not seen anyone mention scrubbing the wheel bead seating area with a stiff brush or a plastic pot scrubber or steel wool etc. in order to have a clean smooth surface to start with. I have often used a steel wire brush to clean steel auto wheels before mounting a new tire, but would not use a steel wire brush on an aluminum alloy wheel.
