Seeing as how the teams designed the cars around these tires and the large volume tires provide a lot of the spring affect there by the suspension of the car has less travel and stiffer suspension set up to compensate for the big voluminous tires. Next years cars will have tires with a lot less volume so the entire suspension system will have to be redesigned to compensate for less travel and a higher spring rate so more travel will have to be designed into the suspension which will make the car heavier, increased complexity and pretty much affect all other engineering decisions in the rest of the car.

What effect will there be in setup/performance/reliability with this being reduced next season with lower profile tires.
