Rob,
It was a poor attempt at a joke.  But actually, when I read reports of blowouts
and tread separations, I don't see any obvious correlation with age.  there
probably is, but it is less than obvious.  And there might be just a smidge of
truth in the idea that if they haven't blown by now they might not.  Only a
smidge, though.

Gary,

It's Sunday morning here in Orlando and I haven't had my coffee yet so I
don't get what you are saying below.

Are you saying it's OK to run tires longer than Michelin's recommendations?

Regards,
Rob

ahhhh yes

the real correlation is the damage caused by blowouts, about $2000 for the
fender wells / paint and propane and Onan doors.

makes a $100 tire seem cheap......

especially since the tire manufacturers say change them every 5 years and
state that as their warranty...

I would not run them much over the Michelin 10 year recommendation for RV tires.

www.michelinrvtires.com/assets/.../TB-Service-Life-for-RV-Tires.pdf

If you are going to run them much longer, inspect them thoroughly, and check them at every stop for temperature differences. Also be especially vigilant for vibrations that feel like tire balance problems no matter how old the tire is. This is usually the first indication of a tire starting to bulge or separate. You are on your own after 10 years.

My removed 12 year old Michelins continued in service on a music company daily delivery van. I think that makes them 15 years old now. The owner drives the van home every night and back to the store in the morning.

Note: Some people like to replace tires after the warranty runs out (usually around 5 or 6 years). I use things all the time where the warranty has run out including every vehicle that I own and the laptop I am using to make this posting.

If you have the money, then replace them every time the warranty runs out.

Come to think about hasn't the warranty run out on your GMC?

Ken, remember that tires maintain their flexibility (and their ability not
to break down in the presence of heat from hysteresis) through the use of
chemicals that release as the rubber is exercised. I will run tires into
deep old age if they are driven daily, such as on the delivery van you
mentioned. The tires on the coach get asked to run a marathon a couple times
a year, but with no training in between.

There are two other points to remember, also. 1.) when a tire on the GMC
blows out, it often does considerable additional damage, and 2.) we aren't
driving GMC's around town for deliveries. We are driving them on the
highway, often quite distant from help.

The last thing I want to worry about as I'm driving the GMC is tires.

On the subject of trends, I can't correlate blowouts based on age, EXCEPT
that nearly all the non-road-hazard blowouts reported on GMCnet have
involved tires that were six or more years old.

That is exactly why Michelin came out with their 10 year recommendation on RV tires. If you look closely they say this only applies to RVs and not to tires if they are used on trucks.

Does anyone know what these chemicals are? Seems to me that it would be good to have it in some kind of "tire dressing" that could be applied to the sidewalls (and treads?). Something like boot grease or shoe polish (paste or liquid)... what ever would give a carrier medium for "these chemicals." It wouldn't replace the benefits of actual use of the tire, but it should slow down the "drying" of the surface rubber.

I figure there would be a market for this type of product especially in hot dry areas, where the high ozone levels dry out tires and other rubber products very quickly.

If there is already a product like this on the market... I haven't heard of it. (Don't even bring up Armor All and all the "silly-cone" based "tire shining" products.)

Mike,

I'm not sure, but a product called Ruglyde is a rubber lubricant. It's what
most tire installers use to lubricate the tire/rim. I first came across it
back in the 60's working at my uncle's service station. We used it for
soaking rubber parts before installation. Shock absorber bushings, front
end bushings etc. When applied to rubber it makes the rubber very
slippery.

I believe it comes in quarts, gallons and assorted size drums. It is
available at NAPA as part number 765-1338 (gallon). When I went to purchase
it last year at the huge NAPA warehouse - the counter guys never heard of
it. It mostly sells out the back door to the tire stores. IIRC it's in
the NAPA book under tire accessories.

The jug states it is a three way product, tire mount & demount, rubber lube
and rubber cleaner and dressing.

I've never tried it as a dressing, but I know it is safe to use.

I may just go find an old tire out back and test it.

Mike,

I don't think a tire dressing would do any good. The chemicals used in tiremanufacture are mixed in the rubber compound and are designed to come to the surface continuously as the tire flexes. Just coating the surface with something that would go away quickly would not do much good. and I would not be too sure you would want to handle them anyway.

I use this stuff:
http://www.303products.com/

I clean the tires with Castrol Super Clean. It does such a good job of
removing dirt that you gotta wonder if it's really good for the tires.
I slather on the 303 after that. I do this at least once a year.
Sometimes more.

I have 7 year old tires on the middle axles on my coach. About to
replace them because, once again, reading the GMCList has me running
scared. They look absolutely great. No checks whatsoever. One side of
my coach only sees sun for maybe 20 minutes a day and I keep tire covers
on the side facing West. I'm guessing the tires have a lot of life left
in them but it's not worth the risk.

Besides, I try to replace one axle's worth every 2 years. A $330 tire
bill instead of a $1000 tire bill. More likely to
replace them two at a time than spend that big money all at once.

I think the biggest variable here is sun damage. I ran my Michelins for 12 years, sold them two years ago and I believe they are still in service. The coach is garaged and out of the sun. I have seen the same type tire crack and blow out in as little as 4 years when parked in the sun constantly. The O zone and sun damage is the biggest tire killer other than alignment and improper inflation. I measure the time factor based on sun exposure and sidewall condition, especially where the sidewall meets the tread. On sun damaged tires, you will actually see cracks open at the seam. Time to get rid of it. Naturally tire manufactures want you to buy new tires every 5 years. That's like my dentist wanting me back every 3 months for a check up. That's when I changed dentists.

On corvette form there is a thread about a car blowing tires just sitting in the shop. The tires are from the 80s and have been inside most of the time. and this is on a 3000 lb car.

everyone is completely surprised, even a guy that sold tires for 11 years. I had to educate them ;-0

Ruglyde is a tire lubricant and it is also used as a tire "dressing".

It used to be a repackaged product of Dow Chemical called RL684. This
was sold by Dow in 55 gallon drums. Back in the late 60's I was the
first salesman of Dow to ever sell a tank truck of this. I sold it to
a repackaged in Brooklyn that repacked it into cans with private
labels for Pep Boys, R & S Auto Stores, and other such retailers.

It is a polyglycol and is good for mounting tires and gives the
surface of tires a nice shine. Unlike oil and petroleum products, it
will do no harm to the rubber, but it will not in any way extend the
life of tires. It cannot soak in and replace the plastisizers that are
in rubber tires when they are manufactured. Once this has migrated to
the surface and evaporated over years there is nothing that can
prevent tires from getting brittle and cracking.

Just plan on replacing your tires before they break up.

Emery,

I wasn't sure about RuGLYDE delaying the aging of tires. I just know it's a
terrific lubricant for rubber. I would also guess that if there was a
product that actually treated the tires to reduce the depletion of the
plasticizers in rubber and/or vinyl - someone would be marketing it.

Upon further review (and putting on my glasses) the contents are listed by
weight as follows:

Water 85-90%
Potassium Vegetable oil soap 5-15%
Ethylene Glycol 1-5%


"Stops rubber squeaks, safe and long lasting. Use on shock absorber
bushings, stabilizer linkage, shackles, rubber grommets, insulating strips
and pads and other rubber parts."

Also recommended as a cleaner for leather & vinyl.

I used RuGlide just after WWII when I worked in a Shell Station. We were instructed to hit every rubber bushing on the car with it, so there would be no squeaks after the lube/oil. Also show the customer the dipstick to make sure the new oil was added and he saw it. We had a competitor that didn't check after lube and you know what eventually happened. New motors were expensive even then.

It seems people are becoming paranoid about tyres suddenly blowing for no apparent reason (maybe in the aftermath of the Firestone/Ford Explorer deal), but in my experience most catostrophic tyre faiures start out as simple as a slow pucture or even underinflation which robs the tyre of the airs cooling effect as it deflates and caused overheating, tread separation and eventual failure.

As far as how long do you run a tyre, I have some tyres on one of my vehicles that are over 10 years old and show no visible cracking or aging so I will continue to use them without concern untill they do show obvious signs of distress.

Of course this scenario only really applies to a quality tyre,you will be lucky to get 5 years out of some of the Chinese, Korean and East Indian cheapo tyres I have seen lately for sale.

Normally I would agree with you but I have several friends who have had the rear tires blow well in advance of the 10 year time limit. Although I'm not proud of it, I did run my Michelins 13 years before replacing them last year with BFG T/A's. Of course XPS rib tires were so hard, I'm not sure if they even had air in them !

Tires that carry more than 50 psi are a different breed of cat than the
tires you run on your daily drivers. I grew up in a logging town where the
local garage also sold log truck tires mounted on split ring rims. They used
to inflate them without a safety cage until they had one blow apart about 80
psi. Knocked the mechanic through the bathroom wall and the tire flew out
through the skylight landing on the roof on the way back down. Broke his
wrist and forearm in several places. They put them under the hydraulic hoist

that screwed onto the valve stem with a long hose attatched after that.
Blowouts on the road can do a similar amount of damage to your coach. I
would never run high pressure tires for ten years no matter what they look
like on the outside mostly because of the infrequent use that these coaches
get. Sitting in the sun does the same thing to the tires that it does to
us.
