200 ft of driving. Flat tire this am. Is this tube worth patching?

That looks like it was mis-installed. The tube aired up and pulled the tube in two, or it was gouged with a tool during installation.. You can patch it there. Was the tube new? Was this the tire that had to be reversed?
 
Almost sure I didn't hit it with a
tool during install. The tire went
on easy with hardly an issue. Tire
shop guy today said I installed it
wrong and it had a fold in it
which ruined the tube?
 
I would say because of the different levels (near the stem base) that the patch has to lay against, a regular patch/cement application might be tough to get a good seal without leaking. Or a shop with vulcanizing but that might get pricey? Maybe some quality windshield sealant urethane in a tube and a home made rubber patch might work but the regular type of backyard mechanic patch will be difficult I would guess.
 
I would give it a small mushroom patch on the inside to outside of the tube, wiggling the patch into the hole then applying glue then light inflation to hold it in place, and wait 3 days. I would then cut off the stem of the mushroom flush with the surface of the outside of the tube, and patch that with a conventional patch. Google mushroom tire patches. Jim
 
I like Jims idea, never seen that done! What I have done on tough spots is use a c-clamp and 2 blocks of wood so as to put a lot of pressure on the patch area, I've had good luck doing that.
 
Give it a shot with a regular patch, what do you have to lose. If the patch holds when you inflate the tube out of the tire it will probably hold when it is installed in the tire. If not a new tube may be in order. Good luck.
 
I was taught to lightly air the tube, just enough to bring it in contact with the inside of the tire, then let it completely deflate, then put the core in and air it up.

I agree, there was a side pull on the stem that ripped it. One of these might work being the tube is fresh.
Replacment Valve
 

As expensive as tubes are, patching it makes sense. I think a patch cut to fit would work. Make sure you scuff it up good before applying the patch. Even just a round patch will hold in a spot like that.
 
JWA ....... I've never been able to get much pressure in a tube by itself outside the tire/rim assembly. The tube just gets bigger and bigger and then I wonder if the patch would hold very well. Inside the tire/rim, there is space restriction and the pressure can go a lot higher and the patch will press against the rim (in this case, against the rim) or against the tire casing.
 
No mater if the tube was installed backward with the stem to wrong side of rim is the tube was not defective it would not have pulled it apart. like that. Id was stem installed too close to the air hole in tube that made it do that. Tire man just doesent want to honor a warenty on that tube. I don;t know if you can get replacement stems or not. A couple of years ago was told they were not avaible anymore.. But if you can get that would be the way to go.
 
I bought a LARGE patch/valve stem from the Goodyear man years ago to patch a tube like that, costs about $8 I believe. It had about a 4" diameter flange to vulcanize onto the tube.
 
Leroy, the guy I bought tires and tubes from said he would make it good. His family runs a farm and has a tire account to save them money. He had the tires delivered to their farm and sold them to me at cost. He couldn't get a replacement tube until Tuesday. And I needed tractor today. So I took it to a local tire shop. They said I installed it wrong and I was at fault. I was wondering if it could have been a defective tube?!
 
(quoted from post at 20:27:09 07/20/18) That isn't a fold issue, it's a separation issue from the heavy valve form. It's junk.

I vote for defective tube also.
Right where the thicknesses of rubber changes.
Probably made in China and was there when it shipped from China.
 
Bad tube but that's why I always get the place to mount the tire I buy the tube from.Then I say its flat, fix it again on your Dime this time.I've had a couple tractor tires go flat after they were fixed,if I take them to my tire guy I intentionally leave them there a couple days before I pick them up to see if they are still holding air.
 
Tf. You sound exactly like me I always leave the tire there for four or five days if I can I because some of these tire flunkys have an extra hard time working on those big tires and not pinching the tube the one guy I sometimes have do tires almost always pinched the tube at least once the other tire place does a good job and I usually don?t have to worry about the job they do
 
The tire stores don't like to put them in, too much risk of failure, especially on an old rotten tube.

But this being a new tube, it stands a better chance, but still risky.
 
my question... why are you putting an old tube in a new tire??? replace that tube, tubes are cheap!
 
We got 2 new tires. And 2 new tubes. One of which went flat a couple days later. Now we have a 3rd new tube. In an new tire. Uggggggggggghgh.
 
That doesn't look like a defect . It looks like it has been punchered not a tare. Tire shop will not repair and if they would they would not stand behind it.I have tire shop come out to farm and change tires and if something like this happens they come out and repair it free.
 
I was getting new replacement valve stems a few years back and I have one guy that will put em on but none of the tire shops will

Rustred, why are you asking about old tubes when he told us that they were new?
 
When the tire shop said fold caused it, he was referring to a fold on the far side trapping the tube then pulling too much tension on the other side, which tore the weak spot.

If that happened, airing it up a little, then letting air back out, then airing again helps. I do that three times sometimes. Also put lots of baby powder in the tire and on the wheel to help the tube not stick and slide into place.
 

Airing it up then deflating and airing a second to helps position the tube and get any wrinkles out.
We started having problems with tubes splitting several years ago and got away from standard bias tire tubes.
No matter what the tire is we only use the thicker radial tire tubes, they hold up better.
 
Just get a big patch like about 4or 5 inch set over a hole in a steel plate with a carriage head bolt hit with a hammer to make a clean cut hole in center than glue it on ovet the stem and all. Would fix hole and reinforce the whole area.
 
Why I patch old tubes.

I bought a new tube for a 7.60x16 tire. It was made in China. I have to add air to it every couple months. The other side, with the original Goodyear 30 year old tube never needs air added.

Maybe it's just me, but pretty much any junk from China is worse than old American stuff.
