Tire change & twisted tubes

So I decided to install some rim locks & finally had the pleasure of doing a tire change. However, when I went to pump the tires back up using a bicycle floor pump, I noticed alot of resistance in getting air in the tires. My gauge would shoot up to 60-80 psi on every pump, before slowly dropping back down. I'm thinking this doesn't feel right.

Please tell me this is normal??? Did I possibly install the tube with a twist?

You probably don't have the pump's inflator on the valve stem far enough to depress the valve core plunger.

Holy crap! Thank god I'm an f'in moron. I was worried I'd have to spend another couple hours taking the tires off again.

Funny, you'd think I'd know better, after doing about a hundred bicycle tire changes. Anyways, now I can go ride this afternoon. Thanks, and please just ignore this thread

Did you mix up a Presta valve with a Schreader valve??

Keeping this thread alive!

Question Help- I've mucked up my first tire change

Hey Folks, could anyone tell me if I've caused too much damage to the bead on this tire, while trying to lever it on the rim? Thanks in advance for any advice.

6" tire irons should be plenty, or you're doing it wrong...

rim lock in, with 3 threads engaged on the nut
tire between rimlock and rim, one side only
powdered tube in, stem through hole, deflated!
lube, lots of it, on the beads
iron on last side of tire, starting at rimlock
break beads again, apply lube
gently air to 5lbs, break beads, lube again
remove valve stem cherry, air quickly to 50lbs... watch bead seat
remove air source, cherry in while deflating (quick hands)
inflate to desired cold temp pressure
CHECK BEAD WITH FINGERTIPS, all the way around both sides.
you'll feel inconsistancies better than you'll see them.


be careful, its always possible for lube to goop out of the rimlock or valve stem holes in the rim, and coat the tire, at a red light ;-)

if you wet the tires shortly after install, expect to see bubbles and goop coming from the rimlock hole, and valvestem hole, in the rim. should stop after and hour. if not... you might have pinched it !

Thanks!

The date mark on the tire reads: 2512. I'm hoping it is not 4 years old.

Still can't get about a 1/4 of it on the rim. I guess I'll have to take it to the "stealer" tomorrow. I appreciate the response.

how much air pressure are you putting in the rim before you give up ?

What everyone will tell you, and they told me, is that you have to have the 'opposite side' of the tire down in the 'dish' of the rim. Of course, if it was just that easy, we wouldn't be asking why the hell we can't get our tire mounted, right?

What i do to get the tire in the well, is to use a 'C-clamp' on one side to slightly pinch the tire so that it will stay down in the dish of the rim. Once I started using that method, I found it easy to mount just about any tire...tubed or tubeless.

Now, if the side you have already mounted starts to ride back out over the rim, just stick a tire iron in at that spot to hold the bead in place.

I konw this reply is much later than you needed, but if may be helpful for future use or anyone else reading.
