If your going off of stock fender hieght, of about 19.5, it's about 13ish" now. So roughly 6". But in just suspension components, it's a 3" coil and 2" spindle.
Whats the offset of the wheels? The only problem I could see is possibly rubbing the bedside with them being wider..the are the exact same height as a 275/40 but 1.5" wider..
I know my 245/50s are damn close to the bedside but my rear isnt rolled.
