CC 38ck Tires

Need to know
1. I know I heard that all CC's come with Nitro. In the tires and not air
2. If this is the case you should not mix the two and if you need too you should remove all the nitro before using compressed air
3. Test have shown that if the two are mixed it causes tires to break down from the inside out
4. Has anyone else heard this in CC's ?
Any info is better than no info and after reading about the tire problems here on the sight if you don't know what's in your tires you might want too . I know I heard this when researching before trading from our Motorhome to this 5er and if so this makes it hard for us campers that check pressures before heading out because I know most if not all don't keep nitrogen in our garages .

Any thoughts ?

Air is about 78% nitrogen.

So many posts on Nitrogen, lots of reading....I use air all the time.

Caterpillar started inflating factory shipped products with Nitrogen tires do to the fact that has the tire heats under use; do to tire loading and tire speeds there is less chance of explosion of the tire carcass.

Now I have never been a proponent of using Nitrogen in automotive tires and trailers. Do to the supply issue of where would I get Nitrogen to replace the Nitrogen I would lose in the tires over time. The average users who will inflated his tires will use air supplied by a compressor at a service station and or his home compressor. They will not go to the bother of storing a 40 Gallon or larger bottle of Nitrogen to inflate his/her tires.

So to me the Nitrogen issue is a mute point. It is nice to have but I will never take my trailer to a tire dealer or RV store to inflate the tires with Nitrogen when the inflation pressure is down. It is more harmful to the tire carcass to run under inflated than to run air in them.

What does Cat make that is (High Speed) to build Heat in Tires? Youroo!!

X2!
As mentioned before the air we breath is already a combo of nitrogen and oxygen.

It is probably a heat issue from weight

I would think "Cat would put water in the tires to give them more traction

High speed scrapers with the driver sitting over the right hand tire. Several operators have been injured/killed from air in the tires instead of nitrogen.
Haul trucks that carry 185 ton plus traveling at 25 mph down the haul road.
Just to name a few vehicles.

Tire Inflation Information
i02096880
Tire Inflation with Nitrogen
SMCS Code: 4203
Caterpillar recommends the use of dry nitrogen gas
for tire inflation and for tire pressure adjustments.
This includes all machines with rubber tires. Nitrogen
is an inert gas that will not aid combustion inside the
tire.
Proper nitrogen inflation equipment, and training
in using the equipment, are necessary to avoid
over inflation. A tire blowout or rim failure can result
from improper or misused equipment and personal
injury or death can occur.
A tire blowout and/or rim failure can occur if the in-
flation equipment is not used correctly, due to the
fact that a fully charged nitrogen cylinder's pressure
is approximately 15000 kPa (2200 psi).
There are other benefits to using nitrogen in addition
to reducing the risk of an explosion. The use of
nitrogen for tire inflation lessens the slow oxidation
of the rubber. Use of nitrogen also slows gradual tire
deterioration. This is especially important for tires
that are expected to have a long service life of at
least four years. Nitrogen reduces the corrosion of
rim components. Nitrogen also reduces problems
that result from disassembly.
A tire blowout or a rim failure can cause personal
injury.
Use a self-attaching inflation chuck and stand behind
the tread when inflating a tire, to prevent personal
injury.

Thanks for the responses , 38FL hit the nail on the head with his post . The Nitro is all a bunch of BS and like I have always thought , and yes most the air we breath is a mixture of both , but I have many a friends and my self included that are either engineers or mechanics and after all the research it is still believed that you should not mix the 2 in a tire (just saying) so with all the problems with tires that are being put on new units from the factory why put nitro in at the factory ?? . First thing I did was to let all the pressure out and refill with air from my own air compressor so I know what's there and I can check the tires before pulling out.

I use air, free air, DW brought me a air compressor and I use it, did not worry me when I put free air in the new 32RL tires along with that other stuff
