Slow leak in tires - found the reason

Feb 23, 2007 16 Replies

I have a 2000 Dakota Quad 4x4 with the nice rims and over sized tires. Over the last two months the driver side tires have lost about 5# of air per week, it was driving me crazy - I though the valve stems were bad but could never find a leak.



I took it to the place where I bought the tires (2 years ago) and their first comment was Aluminum Rims? yes. Oh, you've got corroded rims - it was shocked, almost didn't believe them, as I've never even read about this.



Sure enough, they took the tires off the rims and the dang bead area was corroded - they used scotchbrite on a wheel and made them smooth and shiney again and now they seem to hold air just fine.



I just thought I would pass this along - they said that 60% of their slow leakers are due to this.


Why yes Virgina, aluminumn does corrode ;-) You just can't see the corrosion. It leaves an invisible film. Just happens a lot slower than steel because the corrosion usually keeps an air tight seal to prevent futher corrosion.

When I had a slow leaker spare tire, I had the tire removed, cleaned up the area where the bead seats, and spraypainted it with several coats of enamel. In several years since, it hasn't leaked a bit. Bryan

Ford had problems with porous Aluminum wheels on Mustangs. They came up with an epoxy paint to cure it. Remove the tire, clean the inside, and paint it.

Rumor has it that some people lazer cut their rims to make a small leak!

Umm..why would fools do that?

To relieve pressure buildup when racing for better traction. I take it you don't follow NA$CAR.

That is what air valve is for.

And no I don't watch that garbage. I have a life than to watch idiots drive in circles.

I suspect there is more to racing than driving in circles. However, that's about what it looks like from my point of view.

They race some road courses too. But still, the road course is just a very large crooked circle. I personally like to watch it. I also like to watch idiots drive in a straight line a 1/4 mile at a time.

Yeah right..I once saw them put NASCAR fools on a Gran Prix track back in '96.

There were more wrecks on that once course than all of NASCAR racing season.

It's obvious you don't understand auto racing. There's more to it then driving in circles.

I bet you watch tennis and the garden network.

Yeah, driving fast in circles.

And drinking beer and speaking with a twang

Don't look now, your ignorance is starting to show.

That was showing when he showed up here.

Personally, my attention to NASCAR tapered off as a few things happened: 1. Richard Petty switched to Pontiacs; 2. They quit driving cars that you could at least buy a version of at the dealer; 3. Richard Petty retired.

But I wouldn't put anyone down for making the choice to watch it or anything else. Personal choice is an important part of being free.
