I recently had an opportunity to work on an old Troy-Bilt Snow Blower with a Carlisle Stud Bias Tire - 4.80-8 4 that had a continual leak and would not hold pressure for more than a day. After investigation, I discovered that it "Champagne" sized bubbles coming from an area on the sidewall that I circled in yellow "China" marker. Because of the size of the tire, I decided to purchase the "TireJect Mountain Bike (MTB) Tire Sealant Kit because I didn't require a lot of material to seal the tire. The TireJect Mountain Bike (MTB) Tire Sealant Kit came with an single 8oz container and I used 4 of those 8oz's in this single tire. The TireJect material sealed up the area beautifully. After the sealant cured, I was able to pump up the tire to 15PSI and it has held it's pressure for more than a week now. You can see from the photos, that the sidewalls in that yellow circled area were actually cracked (probably due to the tire sitting flat for more than a year). I highly recommend this product over previous products I have used in the past (Slime).

No more leaks!

Size: 8oz MTB Tire Sealant Kit

This product worked as it should and was easy to install. It connected to the presta stem with no issues. I have had issues with one tire constantly leaking at the bead and this finally sealed the tire.

Bought to hopefully seal bead leak

Size: 8oz MTB Tire Sealant Kit

I’ve been using Stan’s sealant on my tubeless tires for years! I have been having issues with a new tire for a while. It was like the bead wouldn’t seal on a specific spot and my tire was constantly leaking air. The local bike shop couldn’t fix it. I bought this product because it claimed to help seal bead leaks. So far so good! I really didn’t want all the doo-dads for the schrader valves. It took me a minute to figure out how to get the presta valve stem out but once I did- it was super easy to install the injector thing and add the sealant. After inflating my tires- I went for a 20 minute bike ride to get the sealant all around my tires. I’m going to take this bike out to pima-dynamite trailhead next weekend in Scottsdale AZ to see if the sealant holds up!!

Works like a charm!

Size: 8oz MTB Tire Sealant Kit

I’ve used TireJect before. I used it on my golf scooter to eliminate a slow leak. They only hold 14 psi, but over 4 weeks it was down to 10. The TireJect fixed that immediately. Very easy to use.
