Would having a 275/30 19 vs a 265/30 19 affect the torque/power so much to actually lose torque? I am having this discussion with a tire vendor who insists that a 275 will lose approximately 3%. On a 400whp that equates to 12whp. I always thought it was a good idea to go with a wider footprint but if it's that taxing I'd opt for more power to the ground. Thoughts?
