going with a set of rims.. 19x9.5 (f) and 19x11 (r)

lookin to run either 245/35/19 (f) and 285/30/19 (r)
or should i do 255/30/19 (f) and 301/30/19 (r)..

 

255/35/19 in the front and a 305 in the rear (if you can get one in that size) otherwise anything narrower will be really stretched in that 11 inch wide rear rim. Unless you like the stretched look. And you'll probably have to roll your rear fenders too.
