What size tires does a Chevy Silverado 1500 have?
There is no single tire size for all Silverado 1500 models. The stock size depends on trim level and wheel package, with common sizes ranging from 265/70R17 up to 285/45R22.
The Silverado 1500 is offered with 17-, 18-, 20-, and 22-inch wheels across its trims, and tire sizes scale with those wheels. To ensure you have the exact OEM size for your truck, check the door placard, the owner's manual, or the original window sticker for the specific vehicle.
Common stock sizes by wheel diameter
Standard equipment versus wheel upgrades
Most Silverado 1500s ship with a range of wheel diameters. The charts below list typical stock tire sizes you may encounter, noting that exact sizes vary by trim and option packages.
- 17-inch wheels: 265/70R17
- 18-inch wheels: 265/65R18 or 275/65R18
- 20-inch wheels: 275/60R20
- 22-inch wheels: 285/45R22
These sizes cover base and mid-range trims as well as higher-end configurations with larger wheels. Always verify with the specific vehicle's placard or window sticker.
How to determine your exact tire size on your Silverado
To confirm the OEM tire size for your exact Silverado 1500, use one or more of these methods:
- Check the tire information placard on the driver’s door jamb; it lists the recommended tire size for the front and rear axles.
- Consult the owner's manual or the vehicle's build sheet for the original equipment sizes.
- Inspect the tire sidewall for the size marking (for example, P265/70R17); note that replacement tires may be different if a different wheel size was chosen.
- If you’re unsure, contact a Chevrolet dealer with your VIN for the precise OEM sizing.
Knowing the exact OEM size helps ensure proper clearance, speedometer accuracy, and overall handling characteristics.
What to consider when replacing tires
When choosing replacement tires, you should consider more than just width and rim diameter. The Silverado's stability control and anti-lock brakes are tuned to specific tire sizes and load ratings. Here are key factors to weigh:
- Keep the same size on all four corners to preserve handling and traction, unless a dealer approves a staggered setup.
- Match or exceed the OEM load rating and speed rating; LT tires often have higher load ratings than P-rated tires.
- Choose the appropriate tread type for your climate and driving conditions (all-season, all-terrain, or highway tires).
- Check for clearance issues with fenders, suspension, and brake components, especially if using very large wheels.
- Be aware that changing sizes can affect speedometer accuracy, gearing, and warranty coverage.
For most drivers, sticking to the OEM size or an approved dealer-recommended alternative is the safest route.
Model-year notes
GM has periodically updated Silverado wheel and tire options across model years. While sizes like 265/70R17, 265/65R18, 275/65R18, 275/60R20, and 285/45R22 recur, exact availability varies by trim and package. Always verify the specific year and trim using the VIN or window sticker.
Summary
In short, Silverado 1500 tire sizes are not universal. Confirm the exact OEM size for your truck by checking the door placard, window sticker, or owner's manual, and remember that the size will vary with wheel choice—from 17-inch to 22-inch wheels. When replacing tires, sticking with the recommended size and load rating helps maintain performance, safety, and accuracy of the vehicle’s systems.
