New Tires and Stem lost air in the rear

[WylieGibbs]

I was just coming up on 40 miles on the new tires and stems and lost air in the rear. Just had it towed in so I don't know the culprit yet. I suspect a stem was not put in right. Do you think I did any damage to a new Avon?

When my buddy Henry's bike slowly lost front pressure over 30 or so miles, and
then we came to an intersection where he could feel "something was not right",
we pulled over and started checking his tire, it was pretty warm. Depending on
how long you ran on low air, your tire might have gotten real hot - did you check
it when you stopped?

Hope your tire is OK...

If you rode it with no air pressure, you might have damaged the sidewalls.  Sounds like an installation problem.  Check to make sure the bead was seated and the stem has the brace.

I had a blowout at 70 coming back from a Yosemite run. Had it towed to the Honda shop. Turns out the valve stem had cracked off. Went sideways 5 times but managed to stay up. Anyway, they checked the tire and put it back on the bike. Got another 12000 miles out it.

Big screw in middle of tire. Ouch 40 miles and no one here repairs them.

Reordered another one.

For $200. (the cost of another new tire plus labor) I'd take the tire off the rim and take it to any automotive/tire shop for an "inside" repair (read as Patch) and put it back on the bike!!  It will hold and at least you'd only be in for the additional labor.

I agree with Earl. If hole is in the center try and find a plug/patch and do the repair and ride it. I did a rear avon and ran it'll it wore out.

I worked at a service station in HS. Hot patching is not rocket science.  
Buff the spot with a small wire brush.
Should be an area just bigger than patch you are putting on.
Brush off all the dust and wipe with clean cloth.  They make a chemical cleaner that you can use.
Have the patch ready with the backing ready to come off.
Apply a thin layer of patch cement to the spot.  
Light it off with a match or lighter.
While pulling the backing off the patch, count to 5. One, one thousand. Two, one thousand.....
Blow out the flame and CAREFULLY put the patch centered over the hole.  NO it does not have to be exact.  
Roll it over with a small wheel or smooth tool.  This makes sure there is no air pockets left under the patch, also pushes a small amount of material into the hole. Warning, just lite rubbing, you don't want to cause it to lift off.

Ta Da,, you have just Vulcanized a tire patch.

I ran a Stop-n-Go plug in the rear of my wing and towed a trailer for 2500 miles in '09. Continued till it wore out. Never lost air and didn't have to remove the tire. Maybe I got lucky but it worked just fine.

patch it or plug it,,,and you'll be good to go...save that other new tire for the next time.

Put a metal stem valve in there.  Get rid of the OEM style with rubber.  See above about cracking off.
