When your vehicle needs attention and you want a shop you can actually trust, Promex Auto and Tire is worth the drive. We’re located at 31 Elm St in Newport, NH, and drivers from Enfield and the surrounding area have been making that trip for years. Honest, dependable auto repair is hard to find, and when you find a shop that does it right, it’s worth going a little out of your way.
Enfield is a small Upper Valley town built around the outdoors. Mascoma Lake draws sailors and anglers, the Northern Rail Trail offers scenic hikes and bike rides, and Whaleback Mountain brings locals out in the winter for skiing and snowboarding. It’s a close-knit community where trust is earned through consistency, and that’s a standard Promex Auto and Tire has held itself to since the late 1980s.
We’re a full-service shop. Whether you’re coming in for routine maintenance or something more serious, here’s what we handle:
Scheduled upkeep that catches small problems before they become expensive ones.
We use a Snap-On engine scanner and a dedicated EVAP leak machine to diagnose accurately, not guess.
From faulty sensors to wiring issues, we trace the source and fix it properly.
Conventional and synthetic oil changes. We recommend synthetic service at 5,000-mile intervals.
Coolant, brake fluid, power steering fluid, transmission fluid, and more.
We replace worn rotors rather than turning them, for a safer, longer-lasting result every time.
We service A/C systems to keep your cabin comfortable through New Hampshire summers.
We sell and install tires suited to your vehicle and the roads you drive.
Our Hunter alignment machine delivers precise, calibrated alignments after potholes, curbs, or gradual drift.
Rough roads and seasonal driving wear suspension components down. We repair only what your vehicle actually needs.
Full exhaust diagnostics and repair from a shop that knows what it’s looking at.
From diagnostics to engine replacement, depending on what your vehicle needs.
