Umm, incorrect.
As Tirebob already noted, anything that makes a tire either heavier or wider diameter will have a negative effect to fuel economy. Rolling resistance will also affect fuel consumption, and this can be affected by tread pattern, the air pressure, the structure of the belts in the tire carcass and how deep the treads are as that applies to the overall
weight of the tire.
It’s all physics, sometimes it’s helpful to think of the air the vehicle is driving through, pretend the air is water if you wish to exaggerate its effects. A skinny tire does not have to push as much air out of its way as it travels as does a wide tire, so it is more aerodynamic and more energy efficient. A wider, taller or more heavily constructed tire will weigh more, it’s easy to note how extra weight makes it more difficult to both accelerate and decelerate (there are no obese Olympic sprinters). Lots of people don’t stop to think about how heavier tires decrease their braking performance both due to their increased weight but also due to their wider diameter bringing that additional weight further out from the centre of the axle, effectively becoming a longer ‘lever’ fighting against the brake rotor. That’s a double-whammy strike against them there. Some people might think to change their differential axle ratios when they go to a much larger tire, but how many bother with installing a big brake kit to help offset their braking performance loss?
Tires are quite literally where the rubber meets the road, they are the most significant single change to be made as far as a vehicles performance is concerned, and while acceleration is a performance aspect, so is cornering and braking, and winter or wet traction too. I never comprehend why some people cheap out on tires.
