TPMS recommendations needed

New tires are most certainly on my horizon. However, as has been said, new rubber won't prevent nails and other debris from causing a flat. I'd always assumed I'd feel a flat. I learned otherwise on the ND/MT border on our last trip. Pulled off for fuel and discovered one of the trailer tires wasn't just flat, it was gone. All that was left was two beads of rubber around the rim. Thankfully there wasn't damage to the trailer. God only knows how far we'd driven like that.

TST is the brand I'm leaning towards. Thanks for the replies.
