Hi Liz,

Two weeks ago while driving my tractor out in my field, I accidentally ran over a piece of 1/2' rebar that was imbedded vertically in the soil. I was alarmed when I heard the loud hiss of air escaping from my left front tire. I quickly put my tractor in gear and within three revolutions of the tire I noticed that the hiss had stopped.  I immediately jumped off the tractor and noticed the large gapping wound in the tire tread (See picture).  The Commercial Grade of the Ultra Seal had completely sealed the hole!  I drove the tractor a quarter of a mile to my shop and reinflated the tire to 30 psi.  I used this tractor every day since without adding an ounce of air. The price that was paid for installing the the Ultra Seal in both front tires was less than the avoided service call.

Sincerely,
