Flat tire..ugh

[Vranes17]

Ended up Using the frame rail slot since my bottle jack was too big to fit under the LCA. Took tire to mavis and they said there was a sidewall puncture(banghead). F#@% ATs gettin sidewall punctures UGH!. 155$ for a new tire, mounted and balanced.

IT was a very rocky trail that this happened on. What did I do wrong if anything? Should i have been lower than 18psi?

Also find it strange that the bolts that hold on the spare to the back are bigger than the lugs on the wheels. How are you suppose to take the spare off with the tire iron, if the bolts are bigger than the iron!?!?

I did tighten the valve stem with a little tool I bought for that. Still leaks. I checked for holes in the tire, none that I can see so yeah I guess it's leaking around the rim.

Anyway, I'll likely change the tire one of these days to match the other 4 on my Jeep.

Sorry for the threadjacked.gif Vranes17

Bead leak is my bet... You have the stock wheels right? If so very common on alloy wheels. I have had that happen on a few vehicles i have owned over the years. Usually pulling off the tire and going around the bead with a scotchbrite pad to clean off any corrosion and buff the surface out a bit, and then put in a new valvestem, i NEVER pull off a tire without replacing the valvestem, costs like two or three bucks and if you got the darn tire off anyway its a good time to put in a new one, and then remount the tire and rebalance.

I was fighting a slow leak an entire summer on the minivan we had, finally got time to work on it and pulled the tire, nothing in it, no signs of damage, polished up the bead on the tire machine, holding scotchbrite pad against bead while spinning the wheel with the machine, then wiping it down with a rag the same way and cleaning the bead on the tire with some soap and water and rag before mounting, no leaks ever after that.

What brand/model of tire are you running??

And they should be same size unless someone changed out something, they are all the same size on mine, even the special socket for the wheel lock on the spare fits the stock lug wrench.

I have the optional chrome clad wheels, but yeah like you said it's probably a bead leak or maybe a valve leak. I have the damn TPMS on there so hopefully I don't need a new sensor...I'm gonna take it to a shop and see what they can do.

A sidewall puncture can happen off-road. Rocks can be tough. My last couple of punctures off-road were from rocks but luckilly they were on the tread and I was able to plug them and pump them back up. You just nudged the wrong rock and it hit the wrong part of the tire. It can happen. Airing down is better for traction sometimes but the more you air down, the more your sidewalls flex too.

As far as the bolts on the spare goes, someone (prior owner??) must have changed them. You should just change them back to the proper ones.

Why would you need a sensor? It's still doing its job.

I don't know...can they just replace the stem? and not the whole damn thingy

 

[ThunderbirdJunkie]

No. But there is a gasket between the stem and the wheel that can be replaced.

Also, don't go tightening those valve cores yourself. You may overtighten, break, and THEN you'll need a new sensor. Let's hope that hasn't already happened.

What size are they? Where can i get them?

I dont know I didnt change them

Stock lugnuts are 3/4" 1/2-20 thread

Rocks will tear a sidewall out of a tire very quickly...remember you have a couple thousand pounds pushing down on those rocks.....


Good note is you got a new tire....

 

[Ry' N Jen]

The only time I have ever used any jack on the KJ is when I removed the
tyres to install the lift. Then I used a floor jack.
So far I haven't needed a ******** road... Yet!
But this weekend an oil change and tire rotation is in order and I'll use a floor
jack for that as well!
I removed the factory scissor jack from beneath the rear seat and don't carry that anymore.
Instead, I bought a dedicated kit with bottle jack, jack stands, and wheel chocks that reside in the rear of the Jeep in their own tool box.
there is also a floor jack back there.

I thought wrong. Was a bottle jack

 

[RageOfFury]

Errmm...if I...ermmm...did break the valve stem by turning it with the little tool too much. Does that mean I need a whole new valve + sensor? If so, I guess that's only available from the dealer?

Never had a sidewall puncture on the rocks or any wheeling unless running BFG's,buy good offroad tires and they will take a beating.

Hahaha BFG's sidewalls soft too?

 

[tjkj2002]

Extremely,I'd say softer then the OEM crapyears that came stock on a KJ,and I'm talking about the AT's and MT's from BFG.

 

[kj924]

Damn, I was thinking BFG MT's next sneaker swap.....#-o
