    Review by on Oct 4, 2016

    We added 40 oz to 3 of our 11-22.5 tires that had nail holes and they are now holding air with no vibration. I am ordering 5 gallons to treat all my tires.

    Worth every penny

    Review by on May 7, 2016

    I purchased the Ameriseal 32 Oz 2 years ago on my right rear riding mower due to those darn goat heads and it worked flawlessly. Now in the present my left rear is having the same issue and I purchased another 32 Oz bottle and it took care of my flat issue. To this day If I continued to have new goat head punctures the sealer inside clogged it up and no worries of any loss of air. This product is worth the expense and I highly advise anyone to use this. I am a lifer to this product. Way to go ameriseal!!

    Good Product

    Review by on Apr 30, 2016

    I bought this product to use in tube type tractor rears. Works well against thorns. In hindsight, I should have bought the amerseal pump also. I used a couple of pumps that I had that were not quite up to the challenge.

    Just good stuff

    Review by on Jul 25, 2015

    I've know about Amerseal for nearly 20 years and used it quite often, since it was developed. I've seen it do some remarkable things.
    I can't understand why it's not used more. Major Highways will have remnants of tire blowouts every mile. Count them, sometime.
    About 90% are caused from pinholes that result in layer separation and eventual blow out or thread separation. This sealant will fix that.

    Great Product. I use this in my bobcat and have avoided flat tires for a very long time. I also use AmerSeal in my lawn tractor and everything else that has inflatable tires, it works amazingly well.
