I've kind of ignored this problem for a while but I'm tired of refilling my tires every weekend. Ever since I got my 740 with oem alloy wheels(205 55 r16) the air has slowly leaked from them. Especially the rear tires, if I do not fill once a week they go flat. I've looked the tires over and there are no holes/nails/bends in rims. So what the hell is the problem?????????? Any ideas would be much appreciated.

 

An Audi is infamous for the tyre leaking problem...................I have had two of them. The ONLY way you can solve your problem is to dismount the tyres and use a wire wheel to clean the rim of the wheel where the tyre bead makes contact. Your problem will be solved!

 

I've never heard of that but I will look into it. That is certainly more of an answer than anyone else has provided. Thanks

 

Remove the tire and soak it in soapy water.
There also might be corrosion on the rims.
You can also try a bead sealer and see if it helps.

 

That's correct...........it is the corrosion that is the issue and that is why the wire wheel is necessary. All of the imperfections have to be removed or one will continually have a problem. If proud monkey does any racing or drivers schools he will be mighty disappointed when he either rolls out of a rim or the tyre spins on the rim. I have seen that happen many a time during SCCA racing.
