Tyre seal issue - slow pressure loss

Post by mikeyscott » Wed Mar 14, 2018 6:18 pm

Got a from tyre that regularly losses air, had it checked and tyre is fine, but corrosion or something on the wheel. Anyone else this, never had this on any other car?

Solution, refirb / replace wheel?

Don’t drive the 135i much atm. Prob 100 miles per month as daily Volvo C30.

Who said it was the wheel?

Most likely cause would be the valve; my local place would change one for a fiver. Migt be a cracked or distorted alloy, but I wouldnt do anything unless I was certain it wasnt the valve first.
E87 118d, stock, plus PDC control unit drain, Parrot, debadged, Mothercare baby shades (but no babies), and occassionally a good layer of wax. Instantly forgettable, and thats the way I like it.

Local tyre place.

Planning on getting down to Protyre at the weekend to get it all checked.

Has the wheel been placed in a tub of water to check for air bubbles around the alloy edge, with the cold weather the tyre bead can break and cause the tiniest air leak. Could be a case of just deflating the tyre, breaking the bead, rotating the tyre, and re-applying the bead and inflating.

Just get the tyre taken off, clean the head on the tyre and rim, 're seat and fit new valve.

Should be £10 at a garage. £15 at most.

I thought it was just me that had this problem ! I have had three very very slow air leaks over the year I have owned my 135i ..one was a leaking valve , another was an old puncture repair that was still leaking and the third was a very very tiny air leak that only just released the tiniest of bubbles underwater.
I have just bought a plasterers mixing trough off Amazon to dunk wheels in to find these elusive leaks.
