Slow puncture & tyre sealant

sillygoose

One of my tyres has a very slow leak, it goes from 32psi to 28psi over 2 weeks. I therefore have reservations that a repair place will find the leak reliably.

I know that tyre sealant stuff for punctures is only meant to be a temporary fix but wonder how long it would be effective on such a slow leak?

Anyone tried it? tempted to as not much to lose and I would still keep a check on the pressure. There is still some useful life in the tyre so not ready to replace it quite yet.

Take it in get them to have a look and if nothing found get them to put sealer around the bead. That should fix it if not then you probably have to live with it, but it does sound like a leak from the rim.

I bought an old set of rims and tyres and 3 out of 4 leaked at the rim.

The issue is once you use it they may refuse to repair the tyre.

Hi,

unless there is a nail sticking out of tyre, which is usually a good clue,

the first thing to check is the valve core,



remove the dust cap, spit on your finger and put a film of saliva over the valve head, watch to see if it bubbles and bursts,

next, the valve,



maybe you have knocked this when cleaning the wheel and caused a wee crack.

What you have to do to check the tyre yourself is get the wheel off, get it to a bit over pressure and immerse in a tub of water to find the leak.

No different from finding a puncture in a bicycle tube.

My old mechanic claims to have gotten another year out of a tyre repaired with tyre weld.

I've seen how he drives too. That tyre will not have been treated kindly within that year.

Disclaimer: Those things are sold as a temporary repair for a reason, though it's possible that the reason is so that they don't get sued when two year old tyre weld finally gives way and then you crash.

Do what? shhh! I told the wife its illegal to clean cars, drought order still in place!

Well I suppose the tyre sealant could fail but I suppose as the leak is so slow would I be any worse off as I would be back to a slow leak again?

I am thinking the rim leak is likely, it did have a nail in it and it was repaired so its been off and on a bit and possibly driven a bit on flat. In which case I might just replace a bit sooner. I have trained my 10 year old to do inflation duty meanwhile.

Cheers.
