I bought this butyl repair patch and the quality is good. I brought it to the school where I’m learning automotive repair and used it as a teaching consumable. Many students tried it, and everyone thought it worked very well. One thing I would suggest for individual buyers: pay attention to the size combinations in the package. For most car owners, you may end up using only one size more often. Because of that, this mixed-size packaging is probably more suitable for schools, training programs, or auto repair shops where different sizes are needed regularly. Overall, it’s still a good quality product and performs exactly as expected.

Look very useful

Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch

Haven't actually used them yet, but they look like the perfect way to fix a flat. As can be seen they come in various sizes depending on what you will need. All you need to get is some tire patch rubber cement and a good inner tire sealer (I picked up a can of Xtra Seal)

Saved me from buying a tire

Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch, Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch

Took our ancient van on a trip to Florida (from IL) and wouldn't you know we picked up some debris in construction. I was able to plug it however the next morning it was flat again. This time I used 2 plugs to and we were able to get home on that. Realizing this wasn't what I wanted my wife driving around and I didn't wanna buy tires for a van with 250k on it I set out to find some internal patches. I pulled the tire off using a harbor freight bead breaker and some motion pro spoons, used vulcanizing Compound and a dremel and patched it right up. Once the tire is off its a really easy process and I just marked my tire and rim to keep the balance close when it went back together. All appears to be working perfectly with no leaks over the past few weeks. This cost way less than a new tire and now I have more for other holes in the future

worked great for Me

Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch

I have only used two patches so far, and they have worked just fine, You do have to have some tools like a buffing wheel and the vulcanizing glue and a roller wheel to make these patches work as they should, but I am happy with these patches, especially since nobody will repair a motorcycle tire, so this is Your only way to fix them.
