I have a 2018 Z-71 1500- I run 275/65-20’s. I tried the Goodyear Ultra terrain ( Discount Tire exclusively). Absolutely loved them. Load /E and ran 52lbs in them and were solid. Got 54,000 miles out of them. No squishy feeling from weak sidewalls. Went to order again and were back ordered so got talked into the Duratracs. Tire shop filled to 44lbs and super scary changing lanes on highway. I filled to 55lbs and still the same. Going to go to 60lbs and cross my fingers. But already regretting not getting the Ultra Terrains again. Awesome tire. Huge difference.
