Forget the gooey stuff, this product WORKS! See UPDATES 1 and 2
Size: Compact Car, Mid-size Sedan
I've had a slow leak in one of my tires for some time. It's a common thing with chrome plated alloy wheels, they get corrosion on the bead area where the tire seals and then you get a slow leak. This was the only product which is water soluble so it's not going to make a permanent mess inside the tire; additionally, it contains tiny bits of Tufsyn which is the material some tires are made from. So it's not just a liquid that is sealing the leak, it's tiny bits of rubber. I was putting 5 or 6 lbs of air in my tire every few days, and I could see that the tire was getting low. I installed this TireJect per the instructions a week ago and the tire appears to be doing great, despite the fact that we've had some very cold weather. (I didn't want to check it with a gauge while it was this cold out because just in case the tire's valve didn't seal all the way; I'll check with a gauge when this cold snap is past.) While I can't say for 100% sure that there is no more leak, I suspect that the leak has been sealed up completely. This is a product unlike the others and I think it's worth the price. FIRST UPDATE: It has been two months and I haven't had to add any air at all to the tire where I used this product. There was a slow rim leak which was losing about a pound or so per day and it has been totally fixed. The car has sat for several days a few times, including in single digit cold weather, as well as driven regularly otherwise, and the tire hasn't lost any air. I think it's the micro Tufsyn fibers in this product which seal leaks better than some goopy glue stuff other brands are made of. I totally recommend this product! SECOND UPDATE - it's been eleven months since I added this to my tire with the slow rim leak and I have not had to add air a single time. Not once. THIS STUFF WORKS. Forget the slime and foam and get this.
