Tyre Valves not seaing
Discussion
Sorry SEALING can't change the title
Can't get valves to seal well against one wheel after wheel refurbishment.
It was over a year ago so dont think I can go back.
New tyres this week and two valve attempts and still a leak.
Anyone have a magic solution ?
Thanks

Are you sure it's the valve that is leaking and not the tyre bead? If it is the valve, do you mean the valve itself or the joint between the rubber valve base and the metal of the wheel? All tyre fitters have a sealant they can use on the rim and probably also on the joint between the valve and the wheel.
I've actually seen (and successfully repaired this type of leak many times). The following is how I did it:
1. Break the front bead on the tyre (so you don't have to rebalance it), If it is hard or not possible to access the valve with just the front bead broke, dismount the tire from the rim.
2. Remove the valve from the rim (Cut the valve at the butt or inside and tear the remaining part of the valve out, or if you have a sensor, take the nut off and remove the sensor, or with a rubber valve sensor remove the sensor and pull the valve out with a valve puller).
3. Take a wire brush to the inside of the rim where the valve mounts and remove any corrosion.
4. Take a round file to the inside of the hole where the valve mounts and remove any corrosion.
4.5 Inspect the rim for cracks.
4.5 If you have a sensor with a metal stem, inspect the stem for cracks, it is not uncommon for these stems to crack.
5. Install a new valve (or rebuild with new rubber/nut your sensor and reinstall it).
6. Install tyre (if it was dismounted) and seal/seat the beads of the tyre.
7. Dunk or spray the valve to see if it is still leaking.
8. If it continues to leak, disassemble and add bead sealer (or other sealants work as well). You can also just put the sealant in before you assemble the first time, but I do not recommend using sealant on the valve with sensors.
Edit:
A lot of bead sealer will go a long way, I've seen a guy seal a cracked rim with bead sealer, but if the rim is damaged, I recommend replacement.
