I ended up going with 255 40 18 in the back........ and blew them out in a week because the cars alignment was completely FACKKKED(used tires $60). balljoint where blown so I got rear lower control arms godspeed (feel really good-$155 online). and I upgraded the rear tires to 275 40(420 shipped-tiresdirect). Took the car to get aligned(180-firestone-lifetime) emmediatly after putting on all new parts/wheels/tires and Im getting a really bad rub on the inside of the rear driver tire, rear passenger is good. anybody have any clue wtf is going on... I cant keep burning through tires like this lmao - posting pics when the sun comes out.
