The pattern I see is that people are spending money after putting 245's on the front?
I had read in places that 245's on the front were a standard size from the factory once you did the metric conversion. Here is what I found in my searching. I do not know how true this is maybe someone can confirm this? Thanks.
225/60/15 = 25.63" vs. N/A
235/60/15 = 26.10" vs. E60-15 = 26.10" optional on most HP e-bodies
245/60/15 = 26.57" vs. F60-15 = 26.27" standard on Hemi'Cudas
255/60/15 = 27.05" vs. G60-15 = 26.80" standard on rear of AARs
