Broken Cord on Michelin Tire

[Randy Merrill]

Hi Everyone,

The left front tire on my coach has a broken cord. The tread is uneven.
I am getting the tire replaced next week before I head out on a 1,500
mile trip. The tire only has 27,000 miles on it. Does anyone know if
Michelin has a warranty on tires? Has anyone else had a problem with
cord breakage on Michelins?

Thanks,

Randy,

What is the date of manufacture on your tire? Michelin has a warranty on tires, but has probably expired on yours due to age. If your tires are original on the WL, they probably are around 6 years old. Tires on an RV seldom wear out, but routinely have to be replaced due to age. That could be the case here.

Great that you caught this before a major problem. As it its a tire
failure, perhaps you should report it. See the link in this

Hi,
Just a note about reporting the "failure". The request by the NHTSA
(national highway traffic safety assoc.) is for all failures, not just
blow-outs. In the requested information, there is a line
"Nature of the reported failure (slow leak,blow-out, worn etc)" This
can be important for the safety of all BlueBirds and all RV's
(especially those using 315 tires)

you guys should find a trucker or trucking company to buy your tires
prior to 3 or 4 years of age. rotating out a set every year or so
will put new one on the front of your bus and run the tread off the
used tires. its a green thing to do because the tread will be used up
and the casing will be good for a retread. Tire Jobbers, can set you
up with good credit for rotating out your used tires. I screw cords
up jumping curbs and potholes, kinda doubt it is a Mfg prorate thing.

I agree that the 'broken belt' thing is likely a result of a road
hazard. While I haven't had any problems with my Toyo tires on my
coach, over the years, I've had a several tires on my automobile(s)
ruined by construction -- Indeed, a few years ago, when BART was
being built in the SF Bay Area, I lost several tires due to hitting
pavement from a gravel stretch where a subway was being built using
the cut-and-cover method. While I certainly tried to drive carefully
through the extensive construction zones, at night there were times
you just didn't see a transition until you hit it with that sickening
thud. Often the tires don't actually display any problems until days
(or weeks) after the damaging event. The damage occurs, then the
flexing of the tire causes the damage to spread until the tire-cord
is compromised.

Michelin makes generally good, tough tires. It's always possible that
a manufacturing defect was involved, but it's unlikely. More likely
there was a road hazard event that let to the failure. In that case,
most tire companies don't cover the damage (but some companies may
cover road hazard damage), so you'll need to enquire with a Michelin
dealer.

Question. I know that it is recommended to not run tires older then 8
to 10 years maximum. Approximately how many miles are these tires
good for? I haven't heard that mentioned. If a guy runs about 10K
per year can he expect to run out of tread long before the years add
up? I don't typically get more then 35k on car tires I have no idea
what to expect on the MH. I of course understand there are all kinds
of variables to consider but as compared to a car what do you figure
for tread life on the tires you run on your BB'ds?

Are highly inflated tires more prone to these failures? The recall
for the 450LXi specifies running tires at 130 psi. If the tire is at
max inflation then it is less able to deflect to road discontinuities.
Seems like you'll likely have more "broken belt" issues at max
inflation???

Good question David, I know that blow outs are more likely when the
tire is under inflated because the side walls are flexing and causing
heat buildup which weakens the tire. There is some logic however to
the thought that a maximally inflated tire might not handle the road
hazard because of the inability to flex. On the other hand an under
inflated tire might flex too much and result in a stretched or torn
belt(right?). The air pressure does afford a cushion. So my
suspicion is that a properly inflated tire (even if its maximum
inflation) is the way to go. You would hope all this is factored
into the tire design by the engineers who build the darned things.
Just my logic which could easily be wrong. You would not want to
inflate a tire over its max because I think your logic would
certainly apply at that point. Another way to think of this is you
have pressure pushing out from the inside (inflation pressure) vs
forces from the out side which have to be kept in balance.

This is possibly one of the reasons for the mandatory reporting to NHTSA. The newer Wanderlodge has to be inflated to 130 psi for the load. All of them are very close to or over 17,000lbs. Inflating the tire to under 125 leaves it in an overloaded state. Throw in alignment issues-- failure. NHTSA has directed Blue Bird to supply a higher pressure auxillary air pump to allow 130 psi maintanence.
