Tire change & twisted tubes

[StG]

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

Oh no, this thread will stay alive!!! others must learn from your mistake

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

learned a few new tricks while working with the guys at my work.. (eww hardley guys) ....
baby powder in the tire
put the tube in the tire before you mount it
pump the tube up till its just round
put the tire valve thru hole and thread nut on a couple threads
use lots of lube on bead
i use 16" tire irons if i dont use the machine at work...

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 !

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.

.......and should be thrown away anyway just because it is a deathwing. Save yourself some crashing.

to each their own.... i do tires (dirt/street) couple times a week at work and have my own tricks of the trade for dirt tires..... street tires are done on the machine always.. one minute process there.... oh and i like working SMARTER NOT HARDER so thats why i use 16" irons.... leverage is your friend :p

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.
