Hi All,

I seem to have a very slow puncture. It reduces by around 2 to 3 kpa per day. And decreases pressure more when at a standstill than being driven.

Now sorry if this sounds silly but just wnated to understand if repairing the tyre is safe as it is only 1k miles old.
I have a S600 btw.
Not concerned about the money but the tyre shop said they can repair the tyre.

Thanks

It depends on where the leak is coming from...

If you have a screw or nail in the sidewall then they won't repair as the patch can't handle the flexing.

If it's in the tread and over 20-25mm from the edge then they'll repair no problem.

You could also have a porous or cracked alloy or leaking valve

Get the alloy pressure tested, 50psi-ish (not over max of tyre) and dunked into a tank of water. if it is an alloy crack, a good specialist welder can usually repair for much cheaper than a replacement.

That’s a shame it couldn’t be repaired, but at least you have piece of mind now it’s sorted.
