Flat Tire on MoPac or I-35 in Austin — Roadside Guide (2026)

MoPac and I-35 = Austin's Highest-Volume Flat-Tire Corridors

MoPac Expressway (Loop 1) and I-35 through Austin carry the bulk of the city's commuter traffic. Constant construction debris, 100°F+ pavement that raises tire pressure 4–6 PSI, and heavy truck traffic on I-35 make these the two highest-volume flat-tire corridors in Central Texas.

Safe vs. Unsafe Pull-Offs

Safer stretches:

• MoPac north of 2222 (Far West Blvd onward)
• I-35 north of Parmer Lane
• US-183 north of the Y at Anderson Mill

Unsafe stretches (exit even at low speed):

• MoPac between Cesar Chavez and 5th Street (no shoulder)
• MoPac through 38th / Enfield (narrow)
• I-35 between 11th and Ben White (downtown corridor)
• I-35 upper deck (no shoulder at all)

If you're in an unsafe section with any rubber left, take the next exit — a $200 wheel beats a shoulder collision.
