This episode was recorded live on Friday, May 29, 2026 on WNRI 1380AM & 99.9FM in Woonsocket, RI.

This week, Nathan, is joined by his dad and co-host Glenn for a full Ask a Mechanic episode — one of the most information-packed shows of the season. Nathan kicks things off with an update on his Subaru Impreza decision, then Glenn dives deep into listener questions and live caller conversations covering everything from tire pressure monitoring systems to road trip safety.

Glenn answers a detailed email from Sal in Texas about TPMS sensors — how they work, when to replace them, whether to buy OEM or aftermarket, and the surprising history behind why TPMS became a federal requirement. A live caller then joins to ask about a tire plug repair, leading to a thorough breakdown of plugs vs. patch repairs and what your tire manufacturer actually recommends. The show wraps with a practical road trip prep checklist just in time for summer — from checking fluids and spare tires to building an emergency safety kit.

Whether you're a car enthusiast or just want to keep your vehicle road-ready this summer, this episode is a must-listen.
