Can you change from 20 inch tires to 17 inch tires on my gmc sierra 1500?

Yes, you can change from 20-inch tires to 17-inch tires on your GMC Sierra 1500, but there are a few considerations to keep in mind. You will need to ensure that the new tires fit properly within the wheel wells and that the overall diameter of the tires maintains an appropriate size to avoid issues with speedometer accuracy and handling. Additionally, you may need to adjust or replace the wheels to accommodate the different size. It's best to consult with a tire specialist to ensure compatibility and safety.
