Stumped by a Tire Problem

stampchez · 02-09-2011, 09:40 AM

My right rear tire is losing pressure after extended periods of freeway driving. It is a 255 RE-11 on the stock rim. I had the tire replaced after three different shops were unable to find a problem. The problem is continuing with the new tire. I took it to the BMW dealership yesterday and they too were unable to find a problem. I'm running out of options. Any ideas?

2 tires same problem? It's probably your rim.

That would make sense.

I wish somebody would tell me that.

Rim or valve stem.

supposedly no bubbles from the old or the new tire

have you hit any hard potholes with that rim? i'm pretty sure it's the integrity of the rim and not the tire if it isn't holding air.

Use an 11 mm. to tighten up the valve stem into the rim,

If its 2 tires and the same problem is occurring, it sounds to be a rim issue or a valve stem leak. I would double check the valve stem rubber o-ring for any leaks first then move onto diagnosing the wheel itself. The rim could possibly have a crack or slight bend, or even a pin hole leak. Dunk testing would be the easiest route.
