What is the 2019 chevy silverado trail boss tire size?

The tire sizes on the 2019 Chevrolet Silerado 1500 Trailboss are 255/70R17, 265/65R18, 265/70R17, LT265/70R17, LT275/65R18, 275/60R20, and 275/50R22. The psi on Your tires range froM35 to 45 psi depending on the size of the tires You have or are purchasing. What I recommend that You do, is to check Your tires or give an overall eye inspection at least each week. A lot of pressure goes into Your tires and You never know when Your tires will start getting low. As soon as You see them kind of low, try to check their pressure and add if necessary. It could help extend the life of Your tires.
