This problem started recently. Both of the front tires lose air. I have to check the pressure and put air once every 4-5 days.
When this first started I took the wheels off and took them to a local tire shop, techs found some inner corrosion on both rims. They cleaned the rims with some special compound and I had no problems for 2 weeks. The problem came back yesterday. Any thoughts on this?

Are you parking in somebody's drive-way...around here, that's considered the "friendly" way to wise them up, as opposed to having the City tow 'em!

bad valve stem? damaged bead?

[reaper335]

did you pay for the fix? i'd take it back and make them fix it again.. or take it someplace else for a second opinion

[bumere90]

Valve stems were replaced and the beads were corroded but not damaged.

I wouldn't rule out a cracked rim...

[ollie]

+1 for cracked rim.

[ErvGotti]

+1 one on the cracked or bent rim. A small crack or bend on the rim can be just enough to slowly lose air.

r u over weight like the Garfield in your avatar..jk? My friend civic tire needed air very offen due to his 300+ pound.

Check inside the valve, the actual valve core - you can buy a special tool to tighten it, it's like a normal screw. So I'd check that first.

Otherwise, the rim may be cracked... I say take it to a tire shop with a Hunter GSP9700, they can measure the rollout and other things to determine if the rim is bent/cracked.

no one has mentioned this. possible bent or cracked rim.

This was my first thought.

The other possibility is a small puncture, but that would be unusual to be more than 1 tire.


I'd guess that the corrosion is from a split in the rim somewhere which is causing the leak.

How does a rim crack? Hitting a pot hole?

Can you see a crack if there's a crack?

Most tire shops can test the wheels to see if they are holding air and where they are leaking from....or you can get a huge clear tub or a pool and submerge the wheel in water and see if there are tiny bubbles coming from anywhere on the wheel.

Or get a spray bottle of soapy solution and spray all over the tire/wheel, you should see the little bubbles growing in places where there are leaks.

Thanks Woot335Woot! I learned something new.

I had the same thing happen to me, I would lose a few lbs of pressure a day and the low tire light would come every 3 to 5 days. I took it to the dealership 3 times, the first 2 they said they could not find anything, including submerging it (to look for air bubbles i assume), the 3rd time, they kept it overnight and ...they saw 5 lbs missing. it would up being a pin hole in the rim, needed a new rim, which warranty covered since it was only 1 year in. Not easy to find, they need to keep it a faw days to be sure. good luck.

Learned that one from my Dad, he's been a mechanic for like 40 years! It's a wise old man maneuver!

[SpaceGrayE90]

a leak

[ovaltine224]

are you sure the inside tire tread isnt wearing out? maybe they overlooked this. i had the same problem and an alignment cured that

[deliciousE]

I had this problem recently in one tire (two seems rare); turns out I had a small puncture in the sidewall that was diagnosed by dunking the tire into a water bath as described by woot335. The puncture must've been from a pothole or curb rash while parallel parking.

+1. Just remove the cap, and gob of spit over the end of the valve stem. If it bubbles, it's leaking.

I had a buddy that had a similar leaking tire issue. Turns out it was flashing on the bead of the rubber which wouldn't let it seal properly.
