Which would keep the origional diameter better 30, 35 or 40 cross section? and will a 305 fit on the stock 19's or do i have to use a 285/295?
Are you looking to run the same size on all 4 corners or keep the set-up staggered? With the factory 19x9.5" wheels the widest that is recommended/approved is the stock rear size, 285/35-19.
