I bought two of these tire repair kits to put one in each vehicle. I also bought two new jacks for each vehicle. Generally them jacks that come with your vehicle aren’t no good anyways. I had a flat tire way out in the country and I couldn’t get my tire off, with that cheap wrench. I couldn’t get the car jacked up anyways. left me stranded. Not anymore I got two new four-way lug wrenches two new jacks and a tire, patch kit, and two of them little air compressors that you hook up to your cigarette lighter..

Amazon sell a fine selection of replacement fiberized rubber fiber plugs & cement. Read the reviews.

Color: Vivid Orange

This is the only kit you will ever need at roadside to plug a tire & be on your way. This kit has it all. I'm a retired long haul trucker. This is my preferred plug kit. I have stored one of these in all of my trucks & my wife's SUV. You could spend so much more for other plug kits. But this one works. The price reflects the quality of both the tools & all the other essentials you will ever need. I recommend you buy this one. The money you save can be used elsewhere. Note: Amazon sell a fine selection of replacement fiberized rubber plugs & rubber cement. This is where you don't want to skimp on cheap-O plugs elsewhere. These two items are the most important items in the entire system. Be prepared! Always read the reviews & know the sellers reputation before you purchase things. ///////////////
