Couple of months ago, one of my front wheels developed a leak, and I had it repaired. Now, the other front wheel has developed a leak... Taking it to be repaired this week.

The wheels are 7 years old.... wonder if the rear wheels will start leaking pretty soon...

Why are they leaking Phil ? How did they fix it ?

993RS

Don't know why they are leaking... the other one was fixed by dismantling it, applying a special silicone, replacing the intermediate ring and new screws... that should hold. They will do the same with the other wheel... Takes 24 hours to dry the silicone, apply a bit more and then another 6 hours to dry...

Sorry to head that Phil. I just purchased a set of used BBS e88 wheels. They look great, but we'll see if they keep the pressure. A "quick fix" would be to empty one of those 997 emergency tire sealant compound containers into the wheel just "as is". Then drive it around for a while and all that sealant will settle and the leak will hopefully go away. Before the guys at tire shops used to swear at all the mess that the sealant made when it's time to change the tire, but nowadays what's left over from the newer sealants when the tire is removed can be rinsed off with plain water. Just a thought.

That's just as they are. Happen to my E88 too. I couldn't believe it as they were brand new. But you need to seal them with silicon. Didn't do the new screws - just the silicon. They holding now the air since the last 5 month perfectly. Oh yes - I did it at all 4 at one time.

Jack,
Does that mean that they were not originally sealed with silicone? That would explain it, which would be good news, because then there is a chance they will hold now...

Might I suggest :

That's correct. They just got the rubber seal at the joint and that's it. The silicon truly does the job and this should be the way from the factory in the first place.

nice Bart, but I like deep wells...

@ Phil,

is it a problem to be streetlegal with the E88 in CH? In Germany it seems that hey do not have the certivicate from TUV and are not street legal. In the US nobody cares ....

Jack,
Mine are street legal because the middle piece is aluminum and not magnesium. Got them registered properly and accepted in my car's vehicle control papers... They are BBS wheels made for a company called Inden, from which I bought them. This version is street legal in Germany, has the TUV papers...

Hi Phil,

FWIW,..not a modular wheel leaves here without being sealed with silicone seal all the way around.

No leaky wheels in 25+ years.

tropheus

Can you send me a copy of the TUV papers? This would be great. Mine too have the aluminum centers as they are the E88 and not the E28.

Thx Jack

It's correct that they are not sealed with silicone when new. Silicone probably seals the wheel from leaking air but it's a real PITA to clean up once you need to change rimhalves. There must be another compound like Sikaflex or something that is less messy..

Jack, I have been looking around in my papers, but unfortunately must have disposed of them, because they are not recognized here in Switzerland. Sorry...

Here is the site where I bought them:
