I have 2020 Silverado RST and I replaced the original Bridgestone Duelers with BFG TA ko2s. 275/60/20. D load rated. What the tire proper pressure? Installer put 45psi. Obviously truck sticker with original tires listing 35 is off. Need a little advice from the forum as this this first time I've had these tires. They sure look awesome on the truck. Thanks for your help!
