3 of my tires lose air. about 5 lbs every 2 weeks. i have factory alloy wheels. Do some of the sealants work? any suggestions? thanks

 

What year is your truck?

The reason I'm asking is because I remember something about a preliminary query being done on the valve stems on '07 trucks for leaking. I have not heard of a recall yet. My '07 does seem to lose a pound of pressure every two weeks.

 

my truck is a '98. but the wheels are the 5 spoke '02 - '04.

 

with it being on 3 out of 4 wheels. I bet its the valve stems.

The last tire change you had did they replace them?

Go get some soapy water and squirt it on the valve stem see if it bubbles.

 

valve stems don't seem to be leaking, using the soapy water test

 

did you take the cover off? and get around the hole that the stem comes though?

another thing id do is go all the way around the rim of the tire on both sides, this will be easiest takin the tire off.

 

Have the tires been on the wheels for awhile or did you just recently put them on? If you just recently put them on, where the rims 100% clean or did they have some rubber residue or sealant on them?

Where do you live? Accelerated corrosion on the bead/rim due to salt on the roads around this area isn't unheard of.

 

x2 thats why you see the guys clean inside the wheel,

now on the salt factor i live in Florida i dont know anything about that, but you could probably run your finger around the lip and see if its corroded any.

Ive had salt water in my bed trying to get my flats boat off the trailer, and it didnt rust, or corrod anything, but i did clean everything.

 

I don't mind the salt as long as it's on my mashed potatoes but salt from the road gets everywhere . After a few good rains in the spring to wash the roads down, I like to go drive in the heavy rains on the highways. Get all that salt out of the nooks and cranies. Then a good wash and detail.

But back on topic. When I used to work in the garges and did tire work, there would be salt around the bead of the tire when you took it off. I'm not sure if you can really wipe that off without dismounting the tire. Of course tire technology has come a long way in 20 yrs too.

 

you could have corrosion on the beads, have a tire shop pop the bead and see if they are dirty.

 

Are they by any chance goodyear tires? I have seen alot of goodyears loose air like that. Ive had 2 sets of goodyear and both of them did it, put some michelins on it and never lost a pound at all.

 

4.2trimble, i took the stem cap off and sprayed the outside side of the rim.
johnnyd, i just bought the truck a couple months ago. friend got it at an auction for me, so dont really know the history. they've leaked since i've had it

 

So did you see any bubbles?

 

nope

 

Huh, the soapy water didn't show any leaks?!?! Weird! Do you have anything big enough to submerge the tire or part of the tire under water? Tire dunk tank.

Good luck
