Tire Blowout while sleeping

[rvcycleguy]

Pulled the TM to the Texas Hill Country from Houston yesterday for the holiday weekend. First time out since we purchased the unit. PO indicated the tires we about 4 years old with very little use. After set up was completed, we visited with family and then went to bed. Just about to doze off completely, we heard and felt a loud bang. Startled us out of bed thinking the possibilities of hot water tank, furnace, even the water hose from the well source we were using was suspect... I noticed the fender skirt was damaged. Was not that way when we left our home. Tire was still holding pressure but the side wall was partially blown out. We felt lucky that it did not happen on the highway. Before returning home on Sunday, we will replace both tires. Recommendations are being taken if you please.
