Since the frame pivots on the axle at same point of a DRW and SRW pickups, I think the stability comes more from sidewall stiffness and higher rated springs. Until you start picking up a rear wheel I do not feel the width plays a role.

Believe whatever you like…as I stated, not from pontification but from actual real back to back experience from having two identical trucks differing ONLY in SRW vs DRW, there IS an outrigger effect, but honestly I almost feel like I’m barking at the moon, so for those doubting Thomas’s enjoy your comfort providing paradigm and feel free to disregard…![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")

Tire pressure monitoring systems ,available on Amazon work.set up properly will sound alarm when tire is below a specified PSI. Always know your tire pressures.Set to alarm below 50 psi,might give time to pull over. Side note- camper manufacturers sticker campers with an advertised weight.That weight is what you tell your insurance company or show the highway patrol in the case of an unfortunate event..Choose to tell your "HOST" really weighs 6K that is on you. Think about the non coverage and liability. In short ,cheap annoying TP monitors can save your A__ and possibly someone else's. Here's to cheap stuff from..

YES it does happen...caught it (this) before it came apart.

A little closer....

This is why I feel a tad bit safer having 4 rather than 2 under the rear load.
Yes, I personally do know of a fatal rollover caused by a front tire failure and I was lucky when I had a front tire give out (only once). I have had multiple rear tire failures. I will blame it on the brand and have since replaced what I was using. Due diligence...If you don't have a TPM system always check every stop, and obviously if something does not feel right, stop and check, do a full walk around. BTW...always check your spare tire pressure too!...I guarantee most people forget to do this.

Except Bedlam is right. Until the springs flex enough to put the C of G out past the edge of a srw tire, both chassis’s react the same if they have the same spring rate. However 6klbs of tire capacity vs 3500-4000lbs best case is a minimum of 50% greater carrying capacity and subsequently less tire flex.
The outrigger effect is due to the stiffness of the tires and it’s real. It’s just not due to the width until the above happens.
Just like the “dooleys stop faster” theory. Only true once you reach the threshold of traction on the srw tire.
All other things equal, a Dooley weighs more and has more rotating mass to control. Therefore the same brake pressure has slightly less net effect on a dually.

That tread separation is pretty strange. I agree that it's time to change brands.
Of course, you have an extra safety margin with 19.5 Gs on a F450 or similar. The tire structure is much stronger. Sure, you pay for it in ride quality.

Absolutely the brand.
A few years ago I put 6 new Toyo H/T Touring (same as shown in the above pics) on my dually. A few months after installation I got a recall notice, told me to bring the truck back to the dealer so they could check the batch numbers because certain batches were have tread separation issues. Which I did; dealer told me my tires were not covered by the recall and I was good to go.
Since then I've had tread separations on two of the Toyos. I had to pay for the replacements - no warranty coverage at all. Dealer and Toyo refuse to replace the other four tires even though they have barely 20,000 miles on them, and I expect they will fail also.
But it is just this particular model of Toyo tire. I've run Toyo Open Country Mud Terrains for years now on my very heavy 4x4 van; they are all chewed up now because of rocks but I've never even had a flat on one.

Not to beat a dead horse her e but I do agree sidewall stiffness makes a difference.
I am running the Toyo MT's 35 x 12.5 x 18 tires at 80psi when loaded up and around 65 around town so I don't get beat up.
I think they have an "F" load rating.
Unfortunately no warranty comes with these tires and at about 5 bills each that sucks.
I have a little over 20k miles on them and the trad depth started off at 21/32" and I measured a couple of days ago and their averaging about 10/32" so their probably 2/3 gone at this point.
Im guessing I will be replacing in about a year or so with only about 30k miles on them.
For my piece of mind I'm ok with that trade off.

Now lower the “around town” pressure. Betting you’re at 10/32 center of tread and more on the outer lugs. That’s 10-15psi too high on the front of a diesel and 30+psi too high on an unloaded rear axle.
And your kidneys and ball joints will also thank you for it.

You nailed it...I'm not a basher but those are the Toyo HT. Just bad tires. Good call deserteagle56. You know the brand and type to avoid. We have been down that road on bad tires. I was already leary after two other gave outs and it was definitely time to change it up. They were at about 50% anyway so it was a no-brainer.
