need help mounting tire

[GLoweVA]

I got the new tire on, but it won't fully seat on the bead.
I've tried bouncing it MANY times with about 40psi in it.
Is there a trick or technique that I'm unaware of?

Any idead or help is appreciated.

Thanks,
George

I would lower psi to about 10-15 and run a ratchet strap around the circumference.

Squeezing the bead out.

You can break the bead loose again, apply a slippery substance to the bead, I use liquid laundry soap, when it dries it becomes super tacky. Then inflate as needed, up to 60-65 lbs to fully seat the bead. Don't forget to bleed the air down to desired pressure before riding. I also use a rag with mineral spirits to wipe the tire surface down just in case of the presence of a slippery mold release agent.

Thanks John, i used the strap to get the tire to initially hold air. I got it up to about 20psi and released the strap and the bead mostly popped out. I then inflated to about 40 and tried bouncing it to get the last bit to fully expand.

Thanks Phil, i did use a little soapy water when i was using the tire spoons/irons to get the tire on the rim.

The problem i have have is i don't have a compressor. I have to use the pump at the gas station.

Any other idea to try.

I'm using a bicycle pump I have to say I was excited when I got mine set.

Problem with that is it the soap dries up very quickly and the bead becomes stuck right where it is now. If you are still stuck, take it over to any auto tire shop and the fella over there will set you straight for a few $.

I tried that Sat at firestone, but initially the tire wasn't seating enough to even seal so the air just leaked right by, so they couldn't help me. I went home and put the ratchet strap around it and use the gas station pump and got it inflated, but the bead didn't seat all the way.

Cycle Gear wanted $47 to mount and balance it.
So i did it myself. Now I'm on day 2, maybe i should have gone to them.

Everyone has given excellent advice. Lubricate liberally with soapy water between rim and bead, Work quickly before lubricant dries. If stubborn you need to get a little bit animal with the bounce. I keep bouncing on both sides of the unseated area. Sometimes I have the tire/rim bouncing 2 to 3 feet off the ground, just hang on to it. If no success keep changing pressure. If it's the right size tire it will mount.

I have used a rubber hammer on the area. I used soapy water first. Use a lot of it. I used a spray bottle.
You usually have to take the PSI up very high sometimes.

Good luck.

Success! 65Psi was the magic number.
A couple of bounces and bingo. Deflated back down to 30 and then the balancer.
Just need a little weight opposite the valve stem.

Thanks for the quick responses.

Glad it worked out.

George, next time let most of the air out of the tire, then gently bounce/roll the tire on the floor or lay it on a couple of wooden blocks and work the sidewall with a rubber mallet to get the bead to lift up and seat.

If you're going to mount your own tires at home, don't use salt-laden soap, pick up a jug of stuff that's actually designed for lubricating rubber and mounting tires:-

glad you posted that Scot about Ru-glyde I had asked people around here where to get it and they looked at me like I was crazy. I never thought of Napa. Parts stores did in the past sell it in 4 ounce bottles. Next time George use the ru-glyde its much better than soap.

You're welcome, Ron, I didn't know what I was looking for at first but the stuff's great. I had a similar problem with blank looks at one of the local tire dealerships when I asked them where they bought their tire lube and they told me they just used dish soap. When I asked them how they kept the salt out of their customers' rims I got more blank looks and something mumbled about, "Salt? What salt? We don't use salt, we use dish soap!" so Mom's car isn't going back to that place.

My little brothers worked at NAPA so that ended that round of searching.

Wow cant believe none of youse mentioned the fact that many times after removing an old tire the rim itself is dirty and can use a light sanding with a dremel disc sander that removes any debris that might prevent the new tire from making a good seal onto the rim...also makes getting the tire to set into the bead easier....Mark and I do this everytime a tire is changed...JAT
