Flat tire woes

[Punisher666]

So I got home tonight from the last demo derby of the season to find my Deuce leaning to the left. Upon closer inspection I found that my left front tire is going flat. I'm running 395/85 Michelin XML's and for some reason its losing air. I jacked the truck up and checked the tread and sidewalls and found nothing out of the ordinary. Any advice would be greatly appreciated at this point because I cant figure out a reason for it to go flat unless its a faulty tube.

have you tried soapy water mixture to try and locate the leak?

 

[Punisher666]

I havent broken the tire and rim down to get to the tube.

Did you check the valve core?

Best to find it before you break it down IMO. I fill it with air and "borrow" one of my wife's spray bottles. 1 teaspoon detergent, rest water and start at the valve core, next tire beads then tread. It is coming out somewhere.

Once you find it mark it so you know where to work.

straight windex will also work. check the schrader valve first it might just be loose. they loosen up on my tractor trailer all the time.in a pinch or if i'm lazy i put some spit right on the end of the valve stem to check it.

Will do ill let everyone know what I turn up with. Thanks for the possible back saving tips.

Yep, I would go with the schrader valve, Yesterday I needed to brake down some 9X20 to put some 11X20 XL's on and used the stem cap off my spare to pull the schrader valves out of the wheels I was doing. Spent a few hours went back to put the cap back on and found my spare had gone flat. The cap had been the only thing keeping air in the tire could get the schrader to seat so replaced it.

I just got done replacing the valve core and inflated it to 50psi so we shall see if it holds but their was no air leaks at the stem so I should be good to go. Update to come later on or in the AM.

Updates?

 

[Punisher666]

Shes still leaking about 5lbs a day with the new valve core so will be breaking down the tire to find the pinhole in the tube as soon as the weather breaks.

How about putting a little slime in the tire? I figure a pinhole it could seal.

 

[Tlauden]

Going to need a whole lotta slime!! That stuff works great though, IMHO, never used it for any major leaks though

 

[Jtspendy]

wally world has the home slime kit which is intended to do several normal vehicles, should be fine to do yours

 

[Punisher666]

Sounds like im going to be playing with slimer in the near future, if i need help "who am i gonna call?".......

 

[Punisher666]

I put about 40oz. of slime in it today then it started pouring outside so details in the AM.

 

[Punisher666]

Even with the slime it is still leaking, but on the upside she passed inspection with flying colors. Now the fun begins, anyone want to help break down a 395 anytime soon?
