Fix tubeless tire leaks.
Got a garden tractor tire that's always low and you can't find a puncture? Chances are you've got a bead leak caused by a rusting wheel. You can yank the tire, remove the corrosion from the wheel with a wire wheel and then paint it, but my guess is that the tire will still leak air. That's way too much trouble to wind up back where you started. Just install an inner tube and put an end to deflated tires. Write down the tire size and buy the same size tube.
Start by cutting off the old valve stem with a side cutters or utility knife. Next, break the bead (Photo 1). Slide a large screwdriver or pry bar down the center of the wheel and clamp it in a vise. Then pry the bead off the wheel (Photo 2).
Rotate the inner tube so the valve stem lines up with the valve stem hole in the wheel. Tuck the inner tube inside the tire and pull the valve stem through the hole. Secure the valve stem with a spring clamp. Then pry the tire bead back onto the wheel and reinflate (Photo 3).
1 BREAK BOTH BEADS
Cut a 45-degree angle on a short piece of 2x2. Place the angled edge right where the tire meets the steel wheel. Then smack it with a maul to break the tire bead away from the wheel. Move the 2x2 around the entire edge until the bead is completely detached. Flip over the wheel and break the bead on the opposite side.
2 PRY OFF THE TIRE
Pry the tire bead up with a large screwdriver. Hold that part of the tire away from the wheel and use a second screwdriver to pry up another section. Repeat until the entire bead is off.
3 PRY THE TIRE BACK ONTO THE WHEEL
Once the inner tube is in place, hold the valve stem with a spring clamp. Then slide the round handle ends of two large adjustable wrenches (a screwdriver will puncture the tube) under the bead and pry it up and then back onto the wheel.
