Tire blows - great reason to have a dually

[azdryheat]

We were returning from San Diego this afternoon when the inside dually let go on Interstate 8. Wife was driving and didn't realize it was a tire issue; she only heard a loud rumbling. She said the truck handled fine with the blown tire.

All the truck and trailer tires looked fine and I didn't find the blown tire until I thumped on each one. At this point I haven't examined the tire but did see a large slice of sidewall missing from the inside-facing side.

Glad we have a dually as things could have been drastically different with a SRW. I imagine the blown tire would have dropped onto the rim and perhaps a handling issue would have ensued with 18k of trailer (3,500 on the pin).

My point about the TPMS is you stand a chance of knowing that one of your duals is low/flat and you're running on just one overloaded tire. With a SRW, you can see/feel when the tire is low.

Obviously TPMS cannot prevent instantaneous blowouts no matter how many tires you have.

As I noted earlier, I'll take a single super wide over duals any day of the week. Only advantage to duals as drivers brain! Otherwise, traction, braking, mpg's etc, is better with a single!

I agree that TPMS is not a panacea and I have had several tires come apart that I know were full of air. I am just hoping that my problem rate will be reduced with TPMS. So far I can't really say that it has told me of any problems but at least it saves me from having to check the air manually which takes about 20 minutes on my motorhome and I have some peace of mind knowing that there is air in all of the tires, including the trailer which I cannot see while traveling.

I don't get it. Since I don't even have an "inside tire", I don't have to worry about the "inside tire" blowing out. So in theory, having a dually just increases your chances of having a blowout by 50%.

Probably increases the chances by lot more than that since it is much harder to spot a low or flat tire if another one is carrying its weight. I had both inside tires go flat once and the only way I noticed was that I only left one tire track on some soft dirt. Also, the only reason that it went flat was the extenders to make the inside wheels easier to fill let all of the air out. Fortunatly, I had not driven far or fast so all I had to do was get the tires inflated, remove the valve stem extenders and put on a TPMS.

Exactly.

Last year I was hauling a load of freshly picked walnuts with a Freightliner. The trailer had a set of tandem duals. As a rolled into a small town, I heard a large bang and checked my mirror to see a dust cloud coming from the trailer. I pulled off and checked. One outside tire was blown open and the inside one was whole but completely off the rim. The inside tire was likely very low on air for who knows how long. This left the outside tire carrying 8500 lbs by itself (34k on the axles). Now there were two tires to replace.

Many years ago I was a couple cars back from a large dust cloud that formed on interstate 5 in Washington. The dust cloud ended up being a large motor home and toad. The motor home was facing 90 degrees to the travel direction with its tail up on the Jersey barricade. The toad was past it facing backward with a severed hitch. Both of the rear tires on one side of the dually motor home were blown.

My point? Dual tires are there for load capacity, not redundancy. Don't count on them keeping you safe from a blowout, unless you have a TPMS.

Another thing to consider is the fact that a heavier fiver WILL put a SRW truck over it's GVWR. Here in BC, DOT has been known to do roadside weight checks of RV's and they do enforce the GVWR of the truck. If you are over the GVWR of the truck, you drop the trailer on the side of the road, likely get a ticket, and can pick up your trailer from the towing compound with a truck that's rated for the load. I am well under the ratings of my truck and have nothing to worry about in this regard.

At the end of the day to each his own. I have owned both; my last two trucks have been duallies and I will own one as long as I have a heavy fiver. I noticed a considerable difference when I upgraded to one.

You got that right....to each his own.

But why on earth would a dually have higher GVWR and GAWR's than a SRW if there was no difference or benefit????? :h :B

Simple,to carry a heavier load. I'm not saying that a SRW will carry the same weight as a drw.

Yep this


This comes up along with a chime that goes off about every thrity seconds for about ten minutes :M

What was the pressures on your outer duals?

I have a 1500 so no duals 😉

My combined is over 33K.

Dually's are not NEEDED for everyone but it's those extreme situations that make having a Dually well worth it.

Exactly word for word that I told my wife before we bought our 2001 dually. Later she decided my story was the truth.

Really it's simple. If you keep your load light, use a single rear wheel truck. If you roll heavy, use a dually. I've owned several of each... the dually definitely has the advantage in flat tire events.
The notion that a tire is ruined if you ever drive on it overloaded is a ridiculous myth.
Ask anyone who has a dually about what happens when they get a rear flat - generally you can hardly even tell!
Even so, I don't think I I'd drive a dually just for that reason. It's just an extra bonus if you do happen to have one.
