[AT] Tractor tire liquid

[Cecil R Bearden]

I need a little input from you guys.

a couple weeks ago I mounted 2 new 18.4x38 tires on my 2-105 White. 
Tires were mounted tubeless with some type of fluid in the tire.  I 
think it may have been some type of glycol based anti-freeze .  One rim 
needed some welding on a rusted place as the rim had been outside since 
last summer after removing the tire.  We mounted the tires & tubes with 
no problems noted.  Filled both tires with methanol/water solution.  I 
used windshield washer fluid when methanol was so much more expensive.  
Tires hold about 100 gallons, so we added 1/2 of a barrel of methanol.  
filled the remaining with air.  while sowing wheat about 2 weeks later, 
one tire started leaking water at the valve.  I checked the valve and 
found it to be loose from the tube.  2 days later I pumped the fluid out 
and broke down the tire and found valve separated from the tube and a 
1inch long cut about 6 inches from the valve.  I assumed the cut was 
from a pinch with the tire spoon.  Or, maybe the tube was caught between 
the tire & rim.  We inflated and deflated the tube to straighten it 
out.   We also used tire mounting lube to mount the tire on the rim.  I 
repaired the tube last Wednesday.  Yesterday I noticed fluid running out 
of the valve hole on the other tire and a lot of the mounting lube had 
coagulated at the base of the tire.  I jacked the tire up and put the 
valve on top as I did not have time to work on it.

My question is 2 part.   Would the use of mounting lube cause a loose 
tire on the rim and it possibly slip and pull the valve out??   Would 
the use of Methanol be deteriorating the rubber in the tube. and causing 
the problem.  These tires are Speedway 18.4 x 38 8 ply rating.  Tubes 
were 2 different brands.   Gateway the first one, and Doberman the 
second.  I was only pulling a 16 ft spring tooth with a 12 ft harrow 
behind it on 30 acres and later a 16x8 JD drill before the first tire 
started leaking...  The load was not anything out of the ordinary.
