Tires, brakes, and TPMS as one safety stack
Corridor miles punish underinflation and weak trailer brakes. Treat tires, brakes, and TPMS together — not as separate shopping lists.
Active corridor: Montana · Wyoming · Idaho · Washington — case-by-case beyond.
Heat is the enemy. Underinflated tires and dragging brakes both cook components. A TPMS that you actually monitor is worth more than a fancy unused one.
Stack the system
Tires
Pressure for load, age inspection, matching sizes/load range. See aging and pressure-chart guides.
Brakes
Trailer electric brakes need a working controller, clean wiring, and adjusted magnets/shoes per the axle maker.
TPMS
Alerts for heat and pressure loss. Mount sensors so they survive travel; check batteries.
Before a pass
Cold pressures, controller gain check in a lot, listen for drag after a stop.
DIY vs book
DIY
Inflation, visual inspections, TPMS pairing, basic controller setup per manuals.
Book UMRT
Pulling left/right, burning smell, no trailer brakes, or repeated heat alerts — Text with TPMS screenshots.
- Set cold pressure for actual weight
- Verify trailer brakes before highway entry
- Run TPMS every travel day
- Re-check after loading propane/water/cargo
Field reality on the corridor
Measure before you buy parts
Forums love parts lists. A meter, a scale ticket, or a cold pressure check usually beats a guess. Bring photos when you Text Now — year, make, and a clear shot of the fault beat a long thread.
DIY boundary
Owners can inspect, document, and do basic setup from manufacturer manuals. Stop when you smell burning, see structural damage, or the fix needs sealed systems, gas work, or high-current DC you are not trained for.

FAQ
Can I wait until the next stop?
If brakes, tires, propane, or CO are involved, no — stabilize and get help. Cosmetic and planning items can wait.

Parts are quoted after diagnosis. We travel the corridor with common tools and meters; special-order parts are called out before work proceeds.
What does a visit cost?
Trip $75 within 30 miles then $1.50/mi each way; labor ~$150/hr with 1-hour minimum / 30-minute increments; diagnostic $175 applied if you proceed.
