Don't know what to do - car tyre

[Tyredofallthis1]

This may be utterly bleeding obvious to you guys, but I have no idea, I don't know where to start and I don't really know anyone in real life to help.

Yesterday my tyre pressure warning went off for the third time in two months. The two previous times I've got in touch with garages who did the 'you're worrying about nothing, love' and gave me some free air.

I can' t work out how to check tyre pressure and I've never seen anyone add air to their tyres. I think I know which one it is, rear driver's side, because it feels a little off when driving when the warning light goes off.

I think it may be a slow puncture rather than an oversensitive warning light. I have no idea how to check this or what to do if it is. Do I try and get it mended? Or should I just get a new tyre?

Any help really gratefully recieved (also, please be kind. I am doing my best to be a safe driver)

Do you have to reset your tyre sensor system when you have checked / inflated your tyre ? Are you doing this?

Just wanted to give a quick update for all those who were kind enough to give advice.

I went to Kwik Fit who said that they couldn't find anything, but they had brought all the tyres up to pressure and reset the pressure alarm (which I had done in the past). I was told that I should come back next time the alarm went off and then they could check and see what happened. They didn't charge me for this.

I went back two days later after the alarm went off again and they found a very tiny screw in the rear passenger side tyre, so the other side to the one I had been telling them. They seemed a bit embarrassed that they hadn't found it the first time, so were very clear that it was tiny but I understood. It must have been small if it wasn't registering on the sensor for days. They repaired the tyre and charged me £25.

They were really nice as well. I was worried about being ripped off as it must be obvious that I hadn't a clue, but they were lovely. I'm going back there for my services now.

Thank you again to everyone for your help. I am so glad I can come here and ask for help.

Glad you got it sorted OP.

Glad to hear its fixed now OP
