Tire fitment with factory ORG and Bilstein 5100s

[california hauler]

I couldn't find a post specific to my situation so I figured I would ask.

I have a 2020 Ram Big Horn with the Factory Off-Road Package. I have added Bilsteins around and the fronts are set at position 4 for 1.5" lift. I'm wondering if I can clear ~35" tires without issues. Factory Tires are the Falken 275/65R18 C1, and I'm looking at the BFG TA KO2 in LT305/70R18/E. I'm not well versed on tires, can I change from 65R to 70R on the same wheels? I'm specifically looking for All Terrain tires with E1 rating for towing my travel trailer.

These BFGs are about 2.5" larger in diameter so it seems like height in the front will be fine, but will I rub when turning?

Thanks!

Did you ever figure this out. I am wondering the exact same thing for my new truck. Can't believe no one responded

I have the same amount of lift as op.
And i would have rub with 34's on the husky mud guards
So based on that even removing the husky mud guards there would be rubbing with 35's
How much not sure

The rubbing is usually more of an issue with wheel offset and tire width more than height.
