All-terrain vehicles (ATVs) generally use low tire pressures to add traction. While tire pressure may be minimal, ATV tires can begin to gradually leak over time. These slow leaks can lose up a good amount of air over several weeks. Do-it-yourselfers can fix these small leaks in a matter of moments. It's important to carry an ATV all-purpose repair kit for these types of situations. If you get a hole or leak in your ATV tire, use the repair kit to fix it fast.Step 1Examine the ATV tire for foreign objects. Once you have found the problem, pull the object out of the tire or push it into the tire. Locate the hole that will need to be patched.Step 2Determine if the ATV tire has a leak. Pump air to 10psi and cover the hole with soapy water. If bubbles appear from the site of the hole, the tire has a leak.Step 3Remove the rough reamer from the ATV all-purpose repair kit and clean the hole. Put a plug into the insertion tool and force the plug to puncture the hole. Ensure that the plug is secure to prevent future leaks.Step 4Remove the excess plug by cutting it off. Pump air back into the ATV tire until it has reached its desired firmness. Avoid putting too much air into the tire, as this may cause the ATV to slide. Too little air can increase traction.Additional TipsSlow leaks in an ATV tire can be difficult to find. It may take several minutes to form a single soap bubble at the site of the leak. Shaving cream can be used as an alternative to soapy water, as it is more dense and will detect bubbles more easily.Valve leaks on ATV tires are the most common type of problem that occurs. Keep the valve stem cap screwed onto the tire tightly to prevent dirt from entering.Commercial tire sealants are also available, but however, not generally recommended for this type of repair. These products can cause damage to tire rims. Always follow manufacturer warnings and recommendations.
