Given the assumptions you made in the first paragraph, you're right.
There will be a difference in the turn in response. Primarily due to the
larger diameter tires.
Now you have two tires with identical section height, (185mm X60= 111 mm
=4.37") but with different rim diameters. The 14" will have a diameter of
(4.37+ 4.37+14) 22.74 ". The 15" will be (4.37+4.37+15) 23.74" in dia. a
4% difference in diameter.
And too, given that both wheels are 72 spoke, the 15" will exibit
greater flex under the same conditions, due to the longer "lever" effect.
I'm know gonna start some flames (I got my Nomex undies on),but IMHO
for serious high performance driving, Wires aren't the way to go. Under
the best of conditions, the wires will exibit greater flex than even a
set of Rostyles. Wire wheels look aboslutely great on a LBC and they give
the car that special something. But for spirited driving, they leave
quite a bit to be desired.
If money were no object (dont I wish!!!), the hot setup may be to
install a set of
185/60 x15 on 72 spoke wire wheels for use on the street and show
purposes, and purchase a set of 215/50x15 High performance tires and
mount them on 6" wide alloys with splined (knock-off) centers for those
times when you want to go "play".
