Slow Leaking Tire

One downside the the sealants that come in a can is that they can throw a tire off balance. I tried fixing a basketball with a can of tire sealant. It did stop the leak, but the ball was way out of balance and it dribbled like a bowling ball. I had to buy a new basketball. I don’t think an out of balance basketball is life-threatening, but defective tires certainly are. Go to a reputable tire shop and either get the proper fix or replace the tire.
