Tyre dip advice

I have had a bit of a nightmare tonight I thought I would add a little more air to the back tyre as when checking it before the ride it seemed a touch soft but when doing so the side of the tube by the valve went and tore very very slightly so I changed the tube.
15 miles in I took a bend and it went again on inspection it looked like the tyre had rubbed the side by the valve and caused a tiny hole.
I changed the tube which was a bit tricky as I am a newbee but got there in the end as some difficultly getting the valve end of the tyre to sit right.

On inspection at home the tyre seems to have a little dip in it when you run your finger over it, again above the valve? It is on the top of the tyre.

Any ideas guys. I may go and see my LBS tomorrow and see.

    Have you got rim tape?

    Whats rim tape? The inside of the rim is green and all intact?

    rim tape sits inside the wheel and covers the spoke ends to prevent punctures. It obviously has a hole where the valve goes through too.

    Deflate the tube and check the valve is seated inside the tyre properly. When you inflate the tyre make sure that the valve isn't pulled down against the rim - it should be fully inside the tyre and will naturally find its position against the rim as it's inflated.

    Will the tightening nut that comes with the valve not pull the tube towards the rim? Would you recomend not using the nuts?

    The nut is just there to stop the valve rattling in the hole. Put the nut on after the tyre is fully inflated or just leave it off.

    You need to ensure that the valve is radial (points towards the hub) and the valve retaining nut is useful for this when mounting the tyre.
    You also need to ensure that the tyre beads are seated and the inner tube is not trapped beneath. You can back off the nut and push the valve in about 1cm to ensure correct seating, then do the nut up again to prevent the valve wobbling or shifting.
    The nut is not essential but can be useful.

    If you tighten the nut down before installing the tube it helps take the pressure off the join hence preventing tearing at the join( I.e. between tube and rim)

    Is it opposite day or something? You are more likely to get a pinch flat if you tighten it down before installing and inflating the tube

    The nut is not a necessity, it's just there to stop the valve rattling. It serves no other purpose.

    I have had the tube replaced as it was misshapen which is unusual so got a new one and a couple of back ups. Back out Thursday for a stress free ride hopefully
