Tires losing air for no reason

For some reason my stock tire was deflating (16k miles) It went from 35psi to 20psi in about an hour so I filled it back up to 35psi to it off the truck and used soapy water and soaked it and no leaks but was losing air. Soaked steam beads and side walls the whole tire. Deflated over night so changed to spare tire and same damn thing. I'm stumped and no leaks in any of the tires. Any advice?

 

There’s a leak.

 

i just had the same thing happen last week, for me it was pitting on the rim at the bead. it wouldn’t leak without the weight of the truck on it, had a fun time finding that one.

 

That's why I changed out the tire that iv never used

 

How'd you fix that? Might have that issue because it deflated a lot

 

bead sealer, just unbeaded the tire and brushed some where the pits were. mine was going flat every few hours

 

Or the valve in the stem

 

and the core, that will get you sometimes too.

 

Tighten up on the valve (gently). If that doesn’t work try some “Slime”.

 

Take the leaky tire to a professional.

 

Naw

 

Yes it's snug no play

 

Closed. Until Tuesday

 

Do you have a way to submerge perhaps 1/3rd of the tire and watch for bubbles?

 

Bathtub works great for finding leaks. It also has the added bonus of usually pissing the wife off. lol

 

I'm in!

 

Ha! You've been there, no doubt!

 

Yep. The first time I wheeled a 35 through the house I got a lecture. The second time I got a look. Now, she just thinks it's normal. lol

 

That's awesome!
