Yes . I’m choosing a stock tire option as well. 275/65-20

Spoke with my dealer this morning and they can reprogram for any size that was an option from factory. So I’ll be goin gin with 20 inch wheels I believe. Thanks for all the help .

Great information. Mine is also 4x4 and I’ll look into the flash .

Now I’m establishing a good offset . I wanna bring the tires out just a tad . The stock 17s sit in a bit making the stance awful .

New tire will be 285/65-18 .

245/75-17 sir

Thanks! I was just looking at that actually. I didn’t want my tires sticking outside the body so determine offset will be next . I believe stock is 44mm

Thanks ! 245/75-17

Evening all , Just picked up my 2020 2500 Duramax W/T and I’ve gotta get rid of the stock 17’’ wheels . Looking at 18 inch with 285/65-18 . I can’t get a straight answer from anyone if this will cause transmissions or Speedo issues ? Also clearance .

Rookie move ! I thought I was in the 2500 section .
