In the last 3 weeks ive put 3 different tire and wheel sizes on it, and i noticed a significant difference going from a 275-30-24 to a 295-35-24, and then again going from a 295-35-24 to a 305-30-26. For driving daily up here in michigan, i dont think i could do it on a 275-30-24 tire, i could feel everything. When i put on a 295-35-24 tire on the same rims, it was a night and day difference, it adds nearly 2" to the overall diamiater of the wheel, and it felt much better driving on. It felt more like my new, non bagged, silverado, i liked it a lot.
When i swapped on the 305-30-26, it felt more like the 275-30-24 i ran, but it was an improvment over that for sure, and i felt like i could drive on it regularly.
Im either going to run a 295-35-24 with a billet wheel on the truck, or a 305-30-26 with a cast wheel on the truck. I dont think i trust the 305-30-26 enough to run a billet 26, but maybee it will grow on me, idk. On my old ram 1500, i had a 24" billet wheel and bent two of them with a 275-30-24 tire, so im all ways a bit cautious with billet wheels and small tires
