Chevrolet TrailBlazer Spare Tire Fitment Guide
The Chevrolet TrailBlazer used 5x115 mm and 6x5" (6x127 mm) bolt pattern variations from 2002 to 2026 along with tire diameters ranging from 27.0" to 30.0" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Chevrolet TrailBlazer years and options. In this case, 145/60R20 and Full-Size spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Chevrolet TrailBlazer spare tire.
