when checking air pressures yesterday noticed the back passenger tyre was reading just 17psi!. So filled it up to 32psi.
Decided to get it checked at kwik fit this morning and a nail was the culprit:(

Anyway thing is i doing 80miles a day and never noticed any imbalance with the steering of the car, is this usual or what should i have noticed with a tyre running at half pressure?

You should have noticed oversteer. However most drivers are so numb to what their car is telling them that I've known people drive with completely flat tyres and not have a clue.

I don't trust repairs. My life is worth more than patching up knackered tyres.

I take it you don't have a clue how they are repaired. A puncture by a nail is repaired as follows:

1) Tyre taken off rim.
2) Nail pulled out and a clean hole is drilled.
3) A plug shaped like a wide flat topped mushroom is then placed into the hole with the flat bit on the inside of the tyre and glued into place.
4) Tyre refitted, reinflated and rebalanced.

There is no way the plug can fail. The air pressure alone holds it in place.

If the tyre was half flat, does that mean it was only flat at the bottom.

£10 for a puncture repair at my local. Kwik Fit quoted over £20 last time I asked. Halfords Autocentre are about £12 if I remember correctly.

It's a good idea to glance at the tyres before setting off (as well as regular checks with a pressure gauge), especially if you're doing more than just city centre driving.

You do not want a rear tyre to give up on a motorway:

A front 1 is worse, rears are simply good fun, ;)

you are still dependant on the tyre repairer knowing what he is doing though
things like how many cords were broken in the original puncture
did the alien object scratch the sidewall
how long has this tyre been run at 17lbs prior to poster spotting it and is there beads inside the tyre casing suggesting it had overheated at some stage but not blown
same with scrappie tyres you have no idea how many patches they might have inside
for the £20 repair charge i might too have gone the new tyre route

Not really for the main tread. Sidewall definitely, tread area, no.

Utter nonsense, no one will repair the sidewall.

Tyre repairs have to be carried out to :-

BSAU159f is the British Standard to which repairs must be carried out.

All tyre fitters sales and repairers have copies of this and MUST and DO work to it. How does it become a matter of utter confusion amongst you ?
