GM actually had to stop making Blazers because their K.Y.L.E. unit had become self aware and knew more than the guys attempting the gen 3 redesign....

Hey peeps,
I have had the same issue for years, Stock alloys will leak over time for sure. Its only b/c the seal is dirty etc, every fall before my winter tires and stock rims go back on I get them cleaned and sealed. I also have them put the nitrogen in the tires to help prevent coming out to a flat tire9s)..again... |

GM has a technical service bulletin on this very topic. It does happen. Porosity in the casting can allow air to leak out of the rim. This can be diagnosed with a dunk tank and is evidenced by tiny bubbles forming on the surface of the rim between the beads. This isn't something that just starts happening one day though unless the rim has been damaged so...

Nitrogen :icon_doh: Nothing like :icon_urinal: your money away! But that's a topic covered in another thread. :icon_wink:

i want to put propane or either in my tires after a local christmas eve tire slasher went through the niegborhood, only got one of my tires but still, if they had been smoking, it would have been worth blowing up the truck, dont know if any flammable gasses are detrimental to rubber though. imagine a actetelne filled tire being knifed by someone smoking, poetic justice right there. never bought into the nitrogen thing.
