Tyre Pressure Drops

[Hactus]

I need some advice on a little problem where the pressure in one tyre (front left) drops over a couple of weeks. I first became aware when the TPMS alerted on the dash, checking the pressure with a gauge it was 10psi lower than it should have been, so I topped it up and reset the TPMS.

Almost two weeks later the same thing happened, so off to the tyre fitters. They checked for leaks in a water bath and when they couldn't locate a leak they refitted the tyre along with a new valve.

After a further couple of weeks and 300 miles the TPMS has triggered again today. I have again checked and the pressure is 10psi lower than the other front tyre which had dropped 0.5psi over the same period.

Do I have a problem or do I just ignore and keep topping up every couple of weeks? Should I get the tyre replaced?

I would top it up another once or twice and if it keeps dropping you would have to start suspecting a cracked rim or something ??
What wheels are you running ?

17" Devonports. Had thought about a crack and was dreading that :-(

Surely if an OEM wheel has cracked it's warranty work?

I've just gone through all this over the last few weeks.
Pressure drops every week or so, light comes on, and I had to blow back up.
My guys couldn't find a leak after 2 seperate attempts, then finally fitted a new set of tyres on Thursday and all cured.

Thanks for the advice. Will see if it drops again over the next couple of weeks and then see if a new tyre solves the issue.

Before buying a new tyre, might be worth getting a couple swapped over to see if the fault moves with the tyre or stays with the wheel??

Cracking idea, will definitely try this. Could save me wasting money on a tyre. Thankyou.
