Tire fitment question for 2019 Ram warlock

[Wreck It]

2019 Warlock with Nitto P285/65R20's
2 inch lift in front to prevent rubbing (it rubbed without it), and a 1 inch lift in front to maintain the slight nose down profile.

I went with a 4in Superlift with Billstiens. I thought the bigger tires looked like they were packing the wheel wells to much. I regret not going to a 6in lift, but I'm happy as it is.

I've got LT285/65R20 BFG K02's on my truck and they haze zero rubbing on full turn stop-to-stop. I like the little more height I get from the "65" series.

Did you change your tire size in Alphaobd? I have the same tire and can't seem to get the correct size in "mm" to get my speedometer right.

I didn't change the tire size, yet. The speedo difference is minimal and the transmission shifting points are good with nothing done to the programming.

I will be getting an HP Tuners upgrade this summer and will change the tire size then.
