i have them on the front of my car and the side wall is hella stiff. i love them tho. good tire in my view. plus if i'm not mistaken going to a 40 instead of a 45 should bump your gearing up a little and help acceleration. thats what i did with mine went up to a 205-50-15 from a 195-60-15. you can tell the difference. pulls alot harder or at least it feels like it does on the good old ass dyno.
