Hi All,

New poster here.

I currently drive a Seat Leon 21 plate. Earlier in the week, my missus drove over something which caused a roadside puncture. We got it to a nearby garage who replaced the tyre. Since then, then - the tyre pressure has dropped every single day (not by much so its not driveable) but I've had the Alert come up on the dash and had to put air it the tyre.

Now, I know square to nothing about cars - but if we've replaced the tyre - does anyone have any suggestions to what is causing the loss of Air?

Thanks,
 
Welcome, that doesn't sound ideal. I'd be taking it back to the garage as it sounds like a slow puncture which I'd be insiting was their issue to resolve and probably not right upon installation.

The answer is probably yes but I'll ask anyway:
Do you reset the tyre pressure monitoring system every time after inflating the tyre again ?

No worries - Yes, I do reset the monitoring system...

My worry is that isn't a tyre issue, its a Wheel/Rim issue? I just wondered if anyone else had a similar issue before I go back to the garage...

Thanks
 
I would go back to them but i have in the past had a slow drain issue and took it to a tyre place, They resealed the tyre and problem went away.

But of course it could be a damaged wheel but I would expect the shop to tell you that when they are doing the balancing.

Yes if you dont reset it is likely to go off again. Also experienced a bit of sun on one side once which messed things up. That settled down. I was off to Ireland kept badgering me. Check, reset etc. Weird one.

Those garage / petrol pump gauges are suppose to be pretty inaccurate. Don't use them but cross check with a Halford gauge, branded, that memories front and back tyre pressures. Pump to above and let down to desired. That device beaps when you hit the range. So if you dont get them in the tolerance limit and reset etc etc. There will be more experts than me on how it sounds the alarm. A sticker in the door tells you the pressures normal. You dont pump to the soggy comfort figure.
