I just know its a 20" wheel. How do I find out the width?

So I just ordered the Readylift 4"SST lift and Nitto 33"x12.5 Ridge Grapplers. This is going on a 2018 1500 4x4custom. I plan on using the OEM wheels until I can save up for aftermarket. Will it work if I use a 1/2" spacer until then? I don't know what the offset is on the OEM wheels. I went to Readylift's site and looked at the tire fitment tab. This is what it says: 33" Maximum tire diameter 33x11.50 for no rub on a 9" wide wheel with +6 offset 18" - 295/65R18 20" - 285/60R20 22" - 285/50R22 When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 8-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
