luke, I am old and oldschool and I like filling the wheelwells with rubber. It protects the wheels, looks better, gives better traction and more ground clearance (I am NOT into slamming) so I can drive a back road through some woods on family property in Canada. I put 325/50 Kumhos on the rear of my '04 and they hook up well and do the job in the snow for me. I will end up with 305/45s up front after putting some miles on my two spares up front starting this fall. My wife does not like how the 50 series raised the rear of my truck so hers will get 325/40s (already bought) on the rear with 305/45s up front after she wears her tires some more. The section width of 305/45s is a bit narrower than that on the 305/40s so I would really like a 315/45 for up front but they are not made.
