Easy on the hands

These make it much easier to ream tires that have been punctured. It takes the stress off of your hands, forearms and elbows especially when you’re plugging higher ply tires.

Handy Tool for Frequent Flat Tire Repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
Good quality and easy to use. As someone involved in emergency services, we deal with flat tires often, and this tool has been really helpful. The bits are sharp, durable, and make the repair process quicker and cleaner. Great to keep on hand for regular use or in a roadside kit.

Great patches for punctures and the proper way to repair a tyre.
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
Why go to a tire repair shop and spend a fortune when you can do it yourself. However most people don't want to be bothered but for us do it yourselfers this patch set was great. Comes with various patches all in different sizes. If you're not familiar with fixing a tire it's really easy and honestly a scam getting it done. Fun fact the gray glue on the bottom is actually activated when you drive heating up the patch and vulcanizing it to the tire but it doesn't hurt to actually use some rubber cement to seal around the patch to prevent future leaks. I ended up having to use these on one of my motorcycle tires when I ran over a pallet staple, for me the biggest patchwork and once testing and rebeating the tire there was no leakage. Good price for the amount you receive and cost less to repair it yourself than taking it to a shop

Worked Great. Save a Near New Tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I got these because twice this year I picked up a nail in my motorcycle tire. The local shops want to sell tires so they won't patch any tire no matter how new. I used these on two tires, a steel-belted radial and a bias-ply off-road tire. It worked out great, both have been holding air for months now and by doing it myself I saved hundreds of $$$. These are the best way to pemanently patch a tire that's gotten a smallish puncture.
