Leaking Rear Rim

[prw]

The best method of sealing rim bands is to grease the rim very lightly before putting the band on,this seals the spokes and makes seating the band very easy.As for tyre beaders a cheap alternative to the commercially available type beader is a length of about 15mm dia. foam this is used for filling the gaps round windows etc. before sealing with silicone or mastic on construction works,you don't even have to join it just push it in the gap between tyre and rim and as long as its well lubed with soapy water just pops out when the bead seals.If you are looking to buy some of this foam try a construction supplier who specialises in sealants etc.

I just had a bit of a problem with my rim strip but I've got it licked now with some of the information in this thread.

First off the tire was leaking. No dog turds here, so I installed a rubber patch on the inside of the tire (small little puncture).

Now the second time I mounted the rim strip, I applied tire lube to the rim where the strip goes. I used a small paint brush and got a good amount in there. Then I dunked the strip in the tire lube and the valve. I put the valve through the strip and the rim and attached the nut very loosely only to locate the rim strip. I'll get to why in a moment.

Then I got the rim strip around the tire and in the groove. Next I fitted the rim strip in around the valve stem about 20 cm.

Turned the tire around and worked from opposite the valve to the valve on one side getting the rim strip in the groove, then did the other 1/2 of the wheel towards the rim strip.

Next I did the same thing from opposite the valve to the valve on the other side of the rim strip. The rim strip fitted in very easily with just my fingers because of the lube that was all over.

I work the rim strip towards the valve so that the pressure of my fingers tend to push the rim strip towards the valve so that the hole in the rim strip is not elongated at all. I noticed it was an oval when I removed the strip after the 1st try.

Tightened up the valve and using lube on the tire, installed the tire. The tire almost goes on by hand with the lube. Just one lever action and the tires on.

With a tie-down strap tightened around the circumference of the tire and a shot of compressed air the tire started filing and then, pop - pop, it's beaded.

Took the wheel back to the bathtub for air check. It's good! Release pressure to 4 lbs and test again. It's good.

I can do tubeless tires now!

SILICONE!take the tyre back off and the rim tape and silicone all the way around where the rim tape should go. put extra on where the spokes are and refit the valve and put loads under and around that,then put your rim tape on whilst the silicone is still wet. wipe off any execess. leave it to dry over a couple of days and then refit your tyre. if this does not work try a new valve and re silicone. if this does not work then you probably have a puncture. the silicone trick worked for me only last week, although i fitted a brand new rim tape and valve. to make there is no water coming from around the valve and spoke are spit onto your thumb and finger, not a greeny though as they don't work, just rub it around the spokes and valve but you need quite alot, and just watch for any bubble, if non appear then it's obviously a puncture. hope i've helped chris.
