Will 31 x 10.5 inch tires with a 15 inch rim fit on a stock 1990 Chevy 1500 2x4 with a 2 inch leveling kit?

Yes, 31 x 10.5 inch tires on 15-inch rims can fit on a stock 1990 Chevy 1500 2x4 with a 2-inch leveling kit. The leveling kit provides additional clearance, which helps accommodate the larger tire size. However, it's important to ensure that there is no rubbing against the fenders or suspension components, so you may want to check the specific tire brand and model for any potential fitment issues. Additionally, it's advisable to verify that the current wheel offset is compatible with the new tires.
