Nice tire sealant.
Size: 32 oz
This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire

#1 Tire Repair
Size: 16 oz
This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!
