Hey there new to the forum. I have a 2020 sierra 1500 with the 2.7L just changed the tires. Put on LT275/65/20. Stayed the same size. Just more aggressive. Cooper discover at3. Only got about 100km on them. Is it just in my head or is the 4cyl having hard time with tires. Anyone else put LTs on theirs?
