NHTSA Complaint #11515957 — 2022 CHEVROLET SILVERADO 1500

Spare tire and owner's manual provides conflicting, dangerous, and incomplete information. Numerous times the owner's manual warns of numerous dangers about mixing wheel and tire sizes. Yet this truck is equipped with four 275/60 R 20's (20 inch rim) and the spare is 255/80 R 17 (on a 17 inch rim). There is no "T" label on spare. The spare (MAXXIM) is labeled in black "temporary use only" but no information can be found as to what this means. The owner's manual says that this spare (even though a different wheel size and tire size) can be driven up to 70MPH (55 towing) for unlimited time/distance (time and distance is unspecified). The owner's manual does not clearly say that this a "full size spare" or what constitutes a "full size spare." This conflicts with the manual's numerous warnings of numerous dangers of driving with mismatched wheels/tires. The dealership was no help.
