I previously had the 235/70-16 Firestone Wilderness HT tires on the polished 16" x 7" wheels. I just moved up to the 17" x 7.5" aluminum factory wheels with 275/60-17 Falken Ziex S/TZ 01 tires. What a difference! I feel like I just put a rear swaybar on my truck just by changing tires! They grip great, and have not squealed at all cornering! The best I can say is my new Falkens are Falken awesome!
