Tire Fitment Issues

[Paulo M Oliveira]

I used to have the 275/65 R20 Cooper AT3 XLT on my 4th Gen 2014 1500 Sport. The setup looked and performed admirably.
So, when it came time to get my 2021 Laramie Sport I wanted to get the same amazing tire set up.
Unfortunately, the 5th Gen wheel well appears to be slightly smaller on the 5th Gen. On the new truck, the tires rub just slightly at full turn in both directions with the Weather Tech mud flaps.
Did anyone experience the same issue?

what offset are your new wheels? stock is +15 or +25. might need to run a different off set or smaller tire.

New here! Litterly just installed these tires on my classic yesterday. But I went with stock size 275/60. No problems even at full.
