From the link above:
"Advantages of larger rear wheels in an RWD car?
Having a larger diameter rear wheel increases the amount of rubber that contacts the road along the axis of the vehicle which increases your acceleration potential. When you accelerate, much of your vehicle's weight shifts to the rear. By comparison, the front wheels don't need as large a contact patch to take care of steering and braking."
In summary more rubber to the road. |
I did read that and disagree with it. Wheel diameter means nothing to this because if the tires are the same diameter then contact patch is not increased. The Lambos might have larger diameter rear tires but even if they do, a 1" taller tire won't add much to the contact patch. The tire width counts substantially more.
G8x has equal front/rear tire diameters so that is irrelevant.
