What size wheels?
Seems to be a common enough combination of tire sizes for our cars with 9inch wide(front) x 10 inch(or 10.5) wide (rear).
It's the exact same size tires I run on 17x9 rims in the front and 17x10.5 in the rear. The sidewalls r the exact same width, 110.25mm.
I see what you mean. That does make sense. I was looking at it from a set measurement perspective and not a % of the width of the tire. So in actuality its the same. Thanks for explaining that. I appreciate it.
No prob man. I say go for it, those 315s look sick from behind and the 245s don't look too skinny in the front IMO
