The tires on my tag axle were replaced today. I did so because the DOT
dates on them were 1994 (not 2004, 1994, as in 13 yers old). They
showed no signs of age, cracking, anything, just old age. When they
came off, the insides looked absolutely fine. The tire guys said that
while they agreed that changing them out based on age was the "right"
thing to do, if they viewed the tires without knowing the date, they
would approve them for use without pause. Maybe the tags just don't
get as much abuse and wear.

Hello Scott,
I replaced our FC tires at 11-12 years old and they looked fine inside and out.
Everyone
tells me I was lucky not to have a failure on the road. Don't think I'll wait
that long next
time, but it is painful to throw away tires that still look like they have life
in them!

As you probably know, conventional wisdom is maximum use of 7-8 years before
replacement. We had a tire and wheel seminar at the Schulenburg rally and the
expert
said we could extend the usable life by running nitrogen rather than air in the
tires, but
wouldn't state any numbers. His logic for extending life was tires running
cooler and
reduced corrosion of the steel belts since oxygen isn't percolating out through
the tire
structure.

Scott when I replaced my tires they were perfect but had a dot date
of 1989. When I had them removed they showed no sign of wear on the
outside or on the inside as well.

So what did you do with your old ones? I bet the tire guy just sold
them to a re-treader and now they will be recycled to run down the
road on a big rig.

Maybe someday they will have some non destructive testing done on our
expensive tires to see whether or not they are need of replacement.
But for now most us try to play it safe and replace our rubber with
new when the magic date comes up at seven years old.

I left them there. Interestingly enough, they were not the regular
highway treads, but rather the deeper square "drive" treads like one
might find on a dump truck. Don't know why the previous owner had
those on there, he must have got a deal at some point. Frankly, I
don't care what they do with them, I just want to forget about the
cost of replacing them.

Scott,
Why didn't you ask the tire dealer to buy them off you??? When I replaced the
tires on my coach, I asked them before I made the purchase, what would you give
me for the carcass??? They told me they would give me $50 each, I said sold!!!

I find this tire subject interesting and at the same time rather
puzzling as well. How is it that some ten year old tires show "no"
sign of age and weather deterioration and others are described
as "cottage cheese" at about the same age. (And on the inside of the
tire while the outside shows no problem) Now I wouldn't expect them
all to be identical but its difficult for me to understand what the
variables are. It would be helpful to know because obviously then
perhaps action could be taken to preserve them as much as possible.
Obviously covers and proper inflation etc are important. Then there
is the question, can you really visually see what is going on. Could
you have a situation were the tires looks good on all visible
surfaces inside and out and have issues deeper within the tire? I
have to go with the prevailing wisdom on this and trust that I am
doing the right thing and not wasting money. It seems to me there is
not as much science and more religion on this then I am comfortable
with. However, certainly better safe then sorry. I have seen guys
driving tires which I swear you could see the air inside. But it is
extremely hard to throw out tires which look new isn't it?

When you replace good tires, oil and tweak adjustments that are close
to spec, you are performing PREVENTIVE MAINTENANCE (PM). Changing
these things at failure, you are performing MAJOR REPAIR or, in the
case of testing a tire's true life, RECOVERY.

Hello John,

Let me first say, I'm no tire expert, but I can share what we learned from an
expert at the
recent Lone Star Birds Schulenburg rally seminar:

1. Exposure to sun (UV) ages tires and may show up as cracks on the tire
exterior.

2. Low inflation pressures age a tire from excessive sidewall flexing and heat
buildup.
This may show up as cracks on the tire interior and/or exterior. Blue Bird
recommended
tire pressures tend to be low to give a good ride. Generally speaking, tires
inflated to
90-110 psig will have better life than tires run at 60-80 psig.

3. An invisible form of tire aging occurs when the steel belts within the tire
corrode and
loose strength. Exposure to oxygen and moisture are the primary causes of belt
aging.
Improper tire repairs can promote moisture infiltration and corrosion. When the
belts
loose enough strength, catastrophic failure (blowout or disintegration) can
occur.

4. Using pure nitrogen in tires reduces the oxygen exposure and corrosion of
the belts.
Tires also run cooler and this helps slow the effects in item 2 above. The
benefit is
extended tire life. Nitrogen has been used for years in aircraft and mining
industry tires
and is now being used more in commercial and private vehicle tires.

5. There is currently no economically viable method to check the condition of
the internal
tire structure for corrosion or delamination. The useful life guideline remains
at 7-8
years. We can push it another 4 or 5 years, but we are taking a chance when we
do.

Thanks Eric, All this vehicle stuff is open to debate. I was just
thinking it's like changing oil on cars. I tend to go with a
conservative approach in this as well. Better too often rather then
not often enough, so why would I do differently with tires? Consider
that a neglected oil change wouldn't result in a injury or God forbid
a death where a bad tire could? Thanks again for the help. I needed
to vent a little. John
