Question:

Tire size (diameter) and steering response question.?

Will a tire with a larger or smaller diameter have a faster steering response?(if the rear tire diameter is the same in both situations)examples:If the rear and front tire are the same sizeorIf the front tire is 4 inches smaller in diameter than the rear tireWhich will have faster steering response?

Answer:

Aspect ratio, sidewall construction, tread pattern and compound are the critical factors in steering response, not diameter.
Neither.just sounds dangerous to put 4in smaller tires on front they will rotate faster than rear and make car unstable especially steering. If on drag strip ok but 1in diff. frt to rear ok.
In tires the sidewall size will be on of the ways to slow or quicken the steering response. the more side wall you have the more flex between the road and rim which means it will respond a little slower because of the sidewall flex. With less sidewall there is less flex between the road and the rim which means that your inputs will transmit to the road faster. Larger or smaller diameter may not make a difference 1957514 may be smaller than a 2357515 but they both have a large side wall where as a 2355015 would have a smaller sidewall or aspect ratio.
