flat tire

Pete Hall · Jun 8, 2014

Ok,I expect to get flamed on this but tell me what is happening when a rear tube type tire is parked it goes flat overnite in one position but change position and it stays up for months???
Ive had this happen with more than one tire in my life but really never figured out the problem other than changing the tube??
Try to be nice guys!!

Unless someone is messing with you, I would guess there is a tiny leak that is so small, it only leaks continuously when stressed, as when it happens to end up on bottom.

Tire pixies! Fill with nitrogen they do not like that.

It leaks only when the defect is at the point where the flat footprint meets the normal radius of the tire. Right at the edge of the foot print. I've had that happen a number of times.

Tire pixies,
can you explain and why nitrogen?
Very interesting answers.
thank you

Check the valve core, and insert, first, before dismounting tire. Most of the time when I have had a rear with a slow leak, it's in the valve assembly, which can be position dependent!

Dave
Will check that first
14.9 x28 are no fun to break down at 65 anymore!!!!
thanks everybody!!!

A nail in a tubeless car tire won't leak much tip you park on the nail. Maybe some such condition on the tractor tire.

….til you park on it.

We had one that would do that one time and didn't want to replace the expensive tire so I found a position where it wouldn't leak and spray painted a spot on the tire and just made sure it was parked with the mark up. I got by for a good while like that.

pixie

1. A small, magical humanoid creature, similar to a faerie (fairie or fairy); unlike faeries, they are usually not winged; in mythology and fairytales pixies use their magic to play tricks on or otherwise harass people, esp. by sabatoging machines or other technology

In other words the tire must have some pixie dust on it?....I have an Oliver Super 77 Industrial that must have as it has a tire the same way...is maddening.

I think the other replies have pretty well covered the probable causes of the leak, but none answered your question about the nitrogen. Honestly I think the poster was being a bit facetious about it, but nitrogen filled tires tend to "lose inflation" slower than air filled tires do. This happens because the nitrogen molecules are larger than air molecules which means it takes a larger hole for them to escape. The problem here is that the spaces in question are the spaces between the other molecules in the tire, tube, etc, NOT a hole somewhere that"s leaking the air out.

Where I'm at, all I can get is 78% nitrogen.

Is that good enough?

Did you remember to change out your winter air for summer air? Lots of folks forget that semi anual maintenance and then end up with flat tires.

it's also a good time to top off your blinker fluid.

i had that happen on our lil bessy when we first got her.

i filled the back tires with water and the problem went away.

BAnNC · Jun 9, 2014

Got the ones that are self changing. They let it out and I put fresh in regularly.

Most likely has a small hole in the tube that will open when the tire is in the right position. Best thing is to remove tube fill air so it has pretty good pressure then submerge in water to look for bubble.

Ps also look for a small pin in tire run your hand around inside carefully.

air IS mostly nitrogen.If you have a good dryer on your compressor, there is NO difference.
Waste of $$
