I've never had a blow-out on my GMC but have talked to many that have had a rear blow out. The general feeling is that the effect on handling is minimal. My question is whether anyone has had a front blow out at highway speeds and how did the coach react? I'm working on a technical paper for my current employer and would like some feedback.

Never had a front. Left rear, rear though. On the way to Estes Park W.S. Rally the Boss made coment her panel was vibrating. I had noticed the dinette was shaking too. Pulled over and took a look. Couldn't find anything. Drove more,,,,,worse. Checked by raising and spinning all RIGHT side tires. POW. 2 grand,,,, 500 deductible. Held air though. 7 y.old Michelin. Ouch. And we looked for it. Just not well enough. Still hurts. We purchased this one for the newer tires (one of the reasons) but one was an oddball,,,,,PL

Not a blow out but I did loose the entire wheel, hub and drum and all,(RH rear, rear)at highway speed ~55mph and I was able to safely and easily find a good place to pull over and stop. I'm sure that it helped that I have he quadra bag system however.

I had my right rear let go just like that, but it was fast and all ofa sudden, I had the vibration for about 30 seconds then what wounded like a shotgun blast from the rea,followed by a painful twhap-twhap-twhap of the treat deporating and damaging the coach, fortunately the damage is light from what others had esperienced and quite reparable for probably less than my dedcuctable. what really pissed me off was that it happened literally 2 days before I was to put all new rubber and wheels on! that damn tire couldnt make it another 48 hours! it was an old tire, a bridgestone. the handeling didnt suffer too much I was able to roll to a stop where I changed the tire. the rear did waffel however, just keep your foot off the brakes until slow, and keep your fingers crossed that it doesnt tear up too much!

We had a blowout , the driver side last tire. Warm, sunny day.
Driving along near Austin, TX on a highway. It was on the way to the Rayne,
La convention. [2006 ?]
No warning, just a gunshot noise and looked out rear view side mirror to see
debris and dust flowing out of rear of coach.
Stopped gradually at road side, It was actually in a grassy field off road
and down a slope.
.
Inspection found some fibreglas had been torn off above wheel well and a
large dent/crease in Onan access door
Dislodged DOT air line to left bag also. Tire was still on rim. Pieces
missing.
I carry a spare but didn't want to get into it on the highway.
Luckily, after a long wait and no show from Good Sam, a fine Texas trooper
passed and stopped.
No one else even slowed down in over an hour !
He assessed the situation and asked me if it was OK with me for him to call
a local truck tire place.
He did, on his cell phone, and within 10 mins. A service truck showed with a
strong guy, an air compressor, a heavy jack [which did not work, AND a brand
new Chinese tire [Brand under recall] of the correct size [245--75-16] ]
Within 20 min we were on our way and paid with plastic card a total of $140.
The guy was magic. And-----
Heckofa deal.
Tire that failed was ~5 y/o, had perhaps 20k miles , very good tread. It was
a Goodyear, AIR
Don't yet know if and when Sam ever showed.
I headed to the nearest Sam's and replaced the other 3 bogie tires which
were Goodyears of the same vintage; the 2 fronts were much newer. The lack
of symptoms on perfectly good looking tires motivated me to upgrade on the
spot.
What price safety?
Moral -blowout gave no advance warning, no handling problems, but left
unwanted damage.
West system did me good as a DIY person. [long story, no pics] Coach is good
as new.
Chinese tire still on coach. Was not one of the recall numbers

Bob,
It's really amazing that there are no front blowout stories here! Nor
do I have one. But don't I remember someone actually losing the left
front wheel a few years back? Seems like it rolled up under the left
side of the coach... Or is CRS working overtime -- creating stuff to
replace that it can't find?
Wouldn't be quite like a blowout, but interesting anyway. :-)
Surely UHaul maintains records of such incidents on the fleet?

What seems to be the consensus on the blow outs? Under inflation?
I mean aside from the obvious old age tires.
And why the rears? It would seem that the fronts could/would be more affected by under inflation since they have more weight upon them.
Maybe it's all the turbulence around the rears?

It is interesting Ken. The main reason I asked is to get some feedback on how the handling is affected front vs rear. We have about 100,000 trucks in operation at any time and we do track tire incidents closely. About 25% of our trucks are 4 wheel vehicles and 75% are 6 wheel (dually rears). Based on handling considerations during a "rapid air loss" we are recommending that when possible tires with the most tread should be placed on the rear of 4 wheel vehicles and on the front for 6 wheel vehicles. I realize the GMC is not a dually per se, but the handling dynamics during a blow-out may be the same.

I don't envy your trying to come to a conclusion about that. Too many
variables.
But for myself, I think I'll continue putting the best tires on the
front. That's based on: 1. Wanting the best tires on the driven
wheels. 2. Expecting those best tires to have been less abused by
road hazards and running with low pressure -- even if only by virtue
of perhaps being newest. 3. Tires in the rear have "someone to share
the load with" all the time as well as during the failure of one.
That's not quite the conclusion you've reached, probably because of
our front wheel drive.

It is the conclusion I've reached at least for vehicles with 4 rear tires. What most people find counter intuitive is that for 4 wheeled vehicles including cars, is that the better tires should go on the rear. Maybe I'll post the paper on the photo site.

Roger,
Sounds like another argument for never running with low pressure --
started the belts separating, don't you think?

I used to drive old junkers with tires that matched in the time before
radials. I have had sudden blowouts on both the front and rear tires of
several front engine/rear drive vehicles. In one case on the freeway at 70
mph a drivers rear tire blew and the car was into the center divider before
I could take my right arm from around the young ladies shoulder and put it
on the steering wheel where it probably belonged anyway. Those concrete
dividers sure tore the heck out of the drivers side of the car, and bruised
the heck out of my teen age ego. Later on, I had a blowout on the passenger
side front in the same car. It was easier to control and I safely brought
the car to a stop with no drama. Several other cars later & each blowout on
the rear resulted in the car being much more difficult to control than the
front. Based on personal experience, on 4 wheel rear drive vehicles, my
preference would be to have the fronts blow out, not the rears. I have not
had blowouts personally on the GMC, but I helped Gary Berry with his and it
tore the heck out of the skirt and surrounding body panels as well as the
air lines & height controller. Just because of that, I probably would want
the best tires on the forward rear, followed by the rear rears, then to the
front. Really is no substitute for new tires, properly inflated and aligned.
At gas stops, put your hands on the tread of all the tires, if you find one
much different in temperature, probably should find out whats going on.

Yup--a rear blow out can cause an oversteer condition. Most drivers have problems controlling oversteer effects. On vehicles with 4 rear tires however, the oversteer tendency is minimal. A front blow out can cause an understeer condition which is usually controllable--I say usually.

Jim,
Think about it for a minute: A. Front wheels steer and react
significantly to differential loading. B. Rear wheels are fixed dead
ahead and hitting something with one of them doesn't affect
directional control very much.
But your experience is that blowing a rear tire is much worse than
blowing a front one. Why? The difference I see between A. and B.
above is in your statement that those were rear-drive vehicles. The
forcing function became skewed by the blowout.
Isn't it then logical that on a front wheel drive vehicle, blowing a
front tire would be worse than a rear? In fact, since they also
steer, I'd expect a front blowout on a front wheel drive vehicle to be
even worse than a rear blowout on a rear wheel drive vehicle -- front
wheels' tendency to follow differential loading being aggravated by a
skewed forcing function.
Just trying to justify my opinion -- or have someone change it before
it's too late. :-)
