How do you seal the bead of a newly installed tire

Apr 27, 2014 5 Replies

I managed to manually slip a P255/60R16 tire onto the wheel but when I put compressed air into the Shraeder valve (even with the valve stem removed), all the air leaks out before the bead will seal.



What's the trick to seal the bead so I can fill it up?


Put a rope or cable around the tire then use a large screw driver or piece of pipe to tighten it up. Lube the beads with soap, too.

If you have a nylon packing band or something like it, cinch it around the tire tightly then air it.

OK. I'll try, and report back.

It was hard to get the tire OFF the wheel, even with two people and long tire irons, but it was really easy to get it back on.

Now, I'm just trying to fill it with air!

This is how you do it. People have done it this way for years when they had no better way.

That works but if you overdue the ether you can destroy the tire and rim.

For stubborn ones I like to use an old tire. Set the mounted tire onto the old tire with the larger offset side down. Lube the bead/rim area, Now stand on the rim. You want to try to seat one side as far as possible. Now flip the tire over lube the bead and GENTLY push on the rim enough to bring the other bead ring up onto the rim. Now add air and move the rim around a bit till it seats. Now add air to seat the beads fully.
