After two long days in the truck --- 10 hours and 12 hours we arrived home. Ed checked our tires at one of our rest stops on the first day and noticed a bulge on the side of one of the tires. Taking the advise from "tire guy" he took a pin and pricked the tire releasing the air from the bubble. Each time we stopped .... just about every rest stop ... he checked the tire and the tire pressure. When we arrived home he noticed a 2nd bubble was on the tire .... this had happened during the last 2 1/2 hours of the drive.

Ed decided to leave the bubble on the tire and by morning it had grown. Another pin prick and tire looks fine again. Guess who's going tire shopping in the near future.
