What spec wheel?
Typically, an 18x10 would get a 275/40
What chin spoiler are you running?
MMD 19x10s that AM had on sale stupid cheap. They're 45 offset and back spacing is 7.2". From the little interweb research I've done, 265/275 is recommended with 285 being the max. I couldn't find a minimum width though. I'd like to run 275s up front and 285s out back.
That's a MMD front spoiler from AM.
