rust in tires

[n1265]

Hi guys,

I had new tires put on steel rims and I noticed quite a bit of rust in the old ones when I get them back. the rust weighs out at 270 GR in one of the tires
( just over 1/2 OZ ) Is this normal ? something to be conserned about ?

Many Thanks,

Agood cleaning and a coat of paint before remounting the tires would be in order. If you see deep pitting in those areas, or other indication of extreme metal loss, you may want to replace the wheels.

it just means that somewere in its life water got into the tire [gone flat on the bottom ] and then blown back up and used / l,d clean the rims up and repaint

Something like Eastwood's Rust Encapsulator would be good or Por-15 since it would never see the sun anyway.

It is normal in "air" filled tires.

This is just one of the reasons to run nitrogen instead of "air". Ambient air has water molecules included. When the air gets hot (after a long day of running the interstate or because of under-inflation) it condenses and the cooling condensation creates water vapor inside your wheels. That is where the oxidation comes from. Not normally from outside sources.
It's the reason you have a water vapor filter, or drier, on an "air" compressor.

Nitrogen is dry and does not contain a water molecule and as such is less prone to pressure fluctuations due to heat build up.
