Review on 25x8-12 Heavy Duty Doberman ATV Tire Tubes with TR6 Valve - Set of Two by Carl Durant

I couldn't find any soapy water leaks around the tire or valve. I tried sealing it with slime. This tube corresponds to the tire sizes in the packaging photo, which is larger than what is stated in the description. There are several videos on YouTube showing how to break a tire bead with your car, a plank, and how to use your car's weight to break the bead seal. It works!. The bead was very stubborn to break even under the weight of my tractor as these are stock tires on a 2009 quad. When installing the tube, be careful not to pinch it with your tool when you put the tire back on the rim. As you can see in the photo, there is still a lot of tread on the tyre. It also fits my 25x10-12 rear tire size. So I bought 2 packs for future use. Great price for these tubes.
