2022 RAM 1500 AlfaOBD Tire Size Adjustment and Speedometer

2022 RAM 1500 increased tire size to the Falken Wildpeak AT3W 275 60 20 which are 33.1 inch (2642 mm spec), as compared to the 31 inch Dueler HL Alenza stock tires (2462 spec). I adjusted tire size using AlfaOBD, to align the speedometer and gas mileage. Need to bypass the security module (SGW), under dash, which is installed on 2018 greater vehicles.

Also, gas mileage was at 10.8 MPG, which seems insanely low, given spec is 15-17 MPG city. I have 2 inch leveling kit, and the RC Retract Side Step (check my channel for installations) SGW Bypass: Autel FCA 12+8 Universal Adapter Cable Adapter Diagnostic Cable Maxisys Series Scanner https://www.amazon.com/gp/product/B08... $22 OBDLink MX+ OBD2 https://www.amazon.com/gp/product/B07... $120 AlfaOBD https://www.alfaobd.com/ $49
