go for a set of 24s... 20s look too small on a SUV to me, same with 22s. Unless ur gonna bag ur denali, i'd just through some big rims on it and call it a day. By big i mean 24s, not 26s or 28s. They just get tacky
The bigger the rim, the slower ur truck will be... U'll go through breaks faster(but ur doing that anyways with the set of 20s). The gas mileage thing i don't think is true. It prbly effects it some, Between my billet 20s, my stockers, and my chrome 20s, i didn't notice any difference in gas mileage :read:
