A larger wheel/tire isn't necessarily heavier than what comes on the CT - a lot of possibilities here. In fact, I will be putting forth effort to reduce unsprung weight. And, if this is the case, possibly less spinning mass..., acting against the torque. A larger tire doesn't necessarily have a larger contact patch - many factors in play, most importantly, the width of the contact patch. And, just lifting the truck doesn't necessarily mean a greater drag coefficient - if I could emulate a wing with my CT, it would actually benefit the range of my CT.A larger tire is heavier, more spinning mass, thus harder to spin. Also, bigger tire means a larger contact patch, which means more rolling resistance.
Oh, and the truck will sit up taller, so more frontal area...
That is why I think a larger tire could mean a shorter range.
Yes, in a vacuum, sure. Have a nice day!
