Kumho blowout!

[ShrimpBurrito]

My Toyota does have a factory TPMS, so while I don't check its tires as often, I do check them at least every time we take the TM on a trip. I think the last time I checked them was at home though right before we left, so I doubt that will shed any light on the situation, as you're probably looking for running temps.

While cool, they are pretty steady, however, so I rarely have to add or remove air.....maybe 3 times a year.

I do know that the Kumhos have been running pretty warm on this trip -- very warm during the first blowout, but the rim and hub were very warm then too. Unfortunately, however, while I routinely feel the hubs, I don't really remember ever feeling the Kumhos themselves prior to this trip, so I don't have a baseline reference.

On the second blowout, everything was cooler -- warmer than lukewarm, but not as how as before. That was expected though because the ambient air temp was 10-15 degrees lower (low 80's). The new 15" wheels and tires run slightly cooler (lukewarm) than the Kumhos in the same ambient temp.

Oh man...

Very sorry to hear about the second blow out.

Glad to hear that the 15's fit and that the cage protected the plumbing!

Yes, do post a picture!..

Safe trip to you and hopefully all the bad is behind you now.


WMTIRE - Any ideas why it is that sometimes both tires pop on the same trip so close in time to each other? Seems that if both pop one behind the other, more or less, than what is causing them to pop should be common to both tires. If we as owners are doing all we can to insure a correct operating environment then the tire must be at fault? Or does the TM have something unique to it that makes it a little rougher on tires? Perhaps the axle being placed a bit farther back? Just wondering out loud sort of......

Kinda sorta, but from a different angle........possibly in a low tire and how hot it gets.

I'm just trying to look at several things, but most likely it's going to be the tires themselves.........which I have stated from the beginning that only time would tell how well all of our alternatives held up.

The reason I originally asked about checking air pressure on the trailer (but not posssibly the TV), was the air pressure gauge itself. I have seen many of the air gauges (especially these .99 cent pencil gauges you see on a counter display), actually bend/break/damage the valve core. This is the spring actuated core in the middle of the valve stem that holds the air in the tire, that I'm talking about. When the gauge messes up the core, the tire will slowly leak air.......possibly down to the point where it would overheat and blow depending on the load.

Even the gauges we use here in the shop, do this from time to time....and we have to replace the core.

That's why I was trying to determine if you checked all your tires with this gauge or just the trailer tires. I would have guessed that if this gauge was damaging the cores, it would have damaged some on your TV too.........which you said you don't check near as much on, since they have a TPMS.

The two tires, both going out so close to each other, is what has me concerned.

I downloaded your pics and am going to let another tire dealer look at them tomorrow and see if he has an opinion, on why/if they delaminated.

I just hope you are thru with tires for awhile.

I'm thinking that it is merely a simple case of the tires breaking down due to stress. The 14" tires are fairly maxed out without a WDH. Placing and additional couple hundred pounds from just the tension of the spring bars and possibly several hundred pounds when hitting bumps, dips etc, has to shorten the life of the tires.

I went out this morning and bought 2' of 2" steel tubing. I'll be installing my lift kit this week and new tires & wheels in a few months.

Anyone interested in some 14" tires & wheels? The tires are ~one year old and have about 4,000 miles on them. I've never used a WDH with them.
