SLow puncture advice

Having a bit of bother with my rear wheel, I'm losing about 10psi a week.

Now i've still got a good few miles left in the rubber so am loathe to change it unless absolutely necessary.

Now I had a nail in this tyre but it didn't burst it and that was more than 2000 miles ago. so i'm suspecting this is unrelated.

Someone on a run yesterday suggested it may be the valve rather than tyre.

I was planning to get a garage to have a look, but was wondering if a can of tyre weld could be used in this instance?

Cheers

possibly worth running some ultra seal/puncturefix or whatever they've renamed it as through it. I wouldn't want it letting go.

KG-i used the slime puncture stuff and it worked ok but when i got the tyre changed they charged extra due to having to clean the wheel and there tyre machine.
Bit of spit on the valve if it is this take it out the inner workings and re do it.

In my experience, garages / tyre dealers hate tyre weld or anything similar to it.

Leave it alone. Then take it to a garage get them to find where the leak is and put a proper plug into it. That'll last till the tyre is dead and is IMHO a better solution than tyre weld and the such like is.

Liz's SV had a slow puncture and it cost IIRC around £15 to get a plug put into it.

I'd get it plugged as well. The tyre gunk is near enough the same price as plugging the tyre!

+1 for avoiding the slime/tyre weld stuff, never liked it for anything with sporty pretentions.

Valves are easy to check, as mentioned, bit of spit on the valve (and around the base of the stem) will show bubbles if leaking, and replacements are about £1.50 from Halfords or any tyre place and can be changed with either the correct tool (found on the top of some valve caps) or a pair of needle nosed pliers (if it's leaking from the stem base, the whole assembly will obviously need changing).

Likewise on your weekly tyre check ( I presume you do one ) a bit of spit on any likely marks on the tyre will tell you if a plug is required.

A slightly "left field" cause can be polished wheels, as they have been know to "Bleed" air slowly, no real solution apart from coating them, so if you have them be aware this could be a cause.

Cheers Mark.

**** I've just found a piece of glass (3 or 4mm wide) embedded in my tyre picked what I could out with long nose pliers (it was beneath the surface, slightly ice berg style). Doesn't seem to be leaking air, anyone know if it's likely to be a problem?

had this waith an 1.1/4 inch nail, if its not leaking when you removed it , it should be ok, check your pressure for the next few days, using the same gauge, and if it doesnt move its fine.

Excellent cheers KG, I was just a bit worried of running on the tyre and the pressure at speed causing a blow out or something. Is it worth trying to delve into the hole deeper to double check or should I just leave it be and see what happens?

thanks

I was worried about mine with the nail and the guy at the tyre pretty much laughed at me, "if it aint burst it aint gonna burst. That was after riding it 300 miles home, the first 10-15 tentatively.

If your concerned, take it to the next bike garage you pass to put your mind at rest.
