The Chevy Tahoe Z71 is the off-road trim package for the full-size Tahoe — with an off-road suspension tune, a two-speed transfer case, skid plates, hill descent control, and all-terrain tires from the factory. It is the most capable stock Tahoe on unpaved roads. Tire selection should maintain that off-road capability.
Tahoe Z71 tire sizes
The 2021 to present Tahoe Z71 uses 275/60R20 on 20-inch machined-face wheels. The OEM tire is a Goodyear Wrangler all-terrain — the Wrangler TrailRunner AT on most builds — a light all-terrain chosen for the Z71 off-road package.
The Tahoe Z71 weighs approximately 5,400 to 5,600 lbs. All replacement tires must carry the original load rating. This is a full-size BOF-platform vehicle — tire selection should respect the weight.

Frequently asked
What tire size does the Chevy Tahoe Z71 use?
275/60R20 on 20-inch alloy wheels. OEM: a Goodyear Wrangler all-terrain (Wrangler TrailRunner AT on most builds).
How much do Chevy Tahoe Z71 tires cost?
275/60R20: $185 to $310 per tire. A full set of four installed runs $740 to $1,240.
Do I need all-terrain tires on my Tahoe Z71 if I never go off-road?
Not really. The Z71 comes set up for dirt, but if your miles are mostly pavement, a highway-focused tire or a highway-biased A/T will ride quieter, last longer, and use less gas than an aggressive all-terrain. Just keep the load rating the truck came with. Save the chunky tread for a Z71 that actually earns it on the trail.
How do I know when my Tahoe Z71 needs new tires?
Do the penny test and watch for uneven wear, since a full-size SUV this heavy is hard on tires. If you run it off-road, also check for chunked or cut tread along the edges. Fading grip in hard rain and age both matter too — have older tires looked over even when the tread still seems fine.
