Thanks for the reply, Frank. I did weigh my RV five years ago and all was
proper. We usually have about  120 to 150 pounds of food and clothing on
that side and about 50 pounds of tools & misc in storage compartment. My
wife and I weigh about 320 pounds together and we usually run with half tank
of fresh water and dump our tanks after the second half tank refill. The
fresh tank and black tank are on the driver side. All this comes to 800
pounds with the second water reload (650 before the reload). The tires are
not even near max loads. And the motor home is allowed to carry 1050 pounds.
I have been told by others, and read on this NG, that everyone is running
overloaded almost always but they are not blowing out tires.  I blow them
out not being overloaded and only at one tire location! I will try to get
each wheel weight soon and with the RV loaded like we travel. The lawyer bit
is a possiblity but as a last resort.

Thanks, Ed, about the very interesting data you sent, but my spare lasted
longer than the tire on the RV. I blew the first one out at about 900 miles
and it was brand new. My spare got me 600 more miles to Arkansas and back to
California and 18,000 miles more before it blew out 20 miles east of Indio
in the desert at 10 PM. Half hour later I was back on the road, tho. I
brought my RV new and was never notified about this recall. But now that you
mentioned it, THAT spare tire did blow out and all that was left was about 5
inches of sidewall on both sides. So it could have been a weaker tire but we
will never know now. But it could explain blowout Number 2. Thanks.

My tires are not overloaded or underflated. And the tire pressure has always
been proper and checked before and during trips. We usually go on trips
about a couple 100# below max but have been as low as 500# below and
have a tire blow. But as I mentioned in another email to the NG, I have
heard and read on thie group that almost everyone is almost always
overloaded and I don't hear of tires being blown as I do. I will be trying
to
get separate wheel weights as we are loaded soon to check this. Front and
rear wheel weights were proper and below the tire loading factors,
especially with the 235/85s.

The RV came with 225/75 type E tires made by Firestone at the time Firestone
had tire troubles. The first blown one was replaced with no questions asked
by the dealership. After blowing out two more, I changed to 235/85 type E 10
ply tires which were just a little bigger but fit fine and recommended by a
truck tire company here. Blew one of these out 20,000 miles later and then
one at only 1090 miles. In case you are wondering, yes, I changed the gear
to make the speedometer read properly so I was not driving 10 percent
faster. Picked up over 1 MPG more with this change and by using middle
octane fuel. These tires do have a very slight sign of touching the wheel
well but only when going over road dips or body sway and only on the
passenger side. But this does not even wear out the piece of duct tape I put
on the wheel well edge to monitor this so I know it is not causing this
problem.

The 500# below max weight was the total weight for the vehicle. I had 225/75
tires on the RV when brought new so the figures would be higher so I had
plenty or room for weight differences. Why did not the inner tires blow
which theoretically carry more weight? Or a tire on the driver side? Or,
heaven forbid, a front tire?

I think this could be some of the problem but can not prove it. One mechanic
thought he heard that the wrong rims were put on some of the Ford chassis in
1999 and even seen a memo on it but they could never find it again. I do
know that when I put the front tire on the rear it makes my dual tires
closer together. They are only about half inch apart at the bulge by the
road surface with 78-79# pressure cold and these are the Bridgestone tires.
The 225s were the same. I was told by tire people that they could be rubbing
near the road surface but I think these tires are two hard with 95# pressure
in them from running and are both turning at the same rate in the same
direction to be of concern. I have had a tire blow in 60 degree weather
also.

I measured all areas below the frame to the floor and they are within .250
inch. Nothing is broke or seems wrong. I have not checked for an off angle
axle flange or the distance from front to rear axles but I doubt this could
be off. Will check this soon. The body is one inch to the left of center tho
and the wheels are the same distance from the frame. I keep it parked on a
flat concrete floor and have made many measurements.

It was new when I got it but the passenger side tire had a 1/8" groove cut
into the tire sidewall and no one knew how it got there and even noticed it.
They replaced the tire but I think that in haste they replaced all four rear
rims because they are different from the two front rims. That could be
causing this and I have been trying to figure it out for over 50,000 miles
with no help from anyone.

I wish it was an over-weight problem because that would be easily solvable.
Even overrated
tires did not change things. But I still do wonder why Fleetwood changed the
design of the rear tire wheel wells in later models!! I may be doing this
myself soon and that should fix things. But if it was an original design
defect or the body is mounted wrong, I think Fleetwood should fix it. But
there rep told the dealership here not to EVEN TOUCH IT as was told to be by
there body manager. Thanks again.
