Not at all. I get the same on the highway and the same in the city. The cooler weather might be making the engine run better negating any loss on paper, but I won't know for a few months when it gets FLORIDA HOT again I just wanted more rubber on the road. I was actually just looking for steel wheels to hold bigger tires, but alloy wheels were the same price As a bonus now I have 4 full size spare wheels/tires!!!
