I would like to remind everyone that if you add a leveling kit, you void the warranty on your air shocks with limited. I went ahead and got the Nitto grapplers 35 inches x 18 inch x 12.5 I have some rubbing with extreme turns right and left, but it is minimal. The truck runs smoothly up to 75 mph on these tires. The noise is minimal. There are no vibrations until above 75mph and living in California I just don’t do it anyway. You have to keep the alignment intact so every few times after I go off Roading I get the alignment done. Otherwise I’m very happy with the set up And I’ve had no issues. I did have control arm issues with the rear air shocks, but it was covered under warranty. I had the dealership put on the rebel 18 inch OEM rims and the 35 inch tires so it wouldn’t mess with my warranty specifically. That was worth every penny. Gas mileage definitely takes a hit of a couple miles per gallon. Otherwise, there are no issues with the 35 inch Nittos on a 12.5 inch times 18 inch rim. I have the 3.92 and it is smooth and worth the upgrade. Wish I had gone with a higher alternator and two battery system as I tow a 2024 Palamino Reboot 19.4 which is about 8,400lbs loaded and almost max what the truck can handle off road. Ram took down the tow capacity chart which is a very poor thing to do for us. I had to go off the owners manual and what the dealership “guessed” because they never gave me a straight number. I wish I had gotten the 2500 but I got a great deal on the 1500 so I’m not going to trade up. Especially in this market. Overall, I have been extremely pleased with my 2021 1500 limited especially as I have neck and back injuries from a job injury, which is why I went with this truck as well as in entry exit mode. It clears the top of my garage by less than half an inch. so I’m stuck with the limited and no lift kit.
