so i need tires bad on my everyday truck. the correct size is 255/70/16 i got 2 new 215/70/16. this is on a 2003 f150,i know its a ford but its a truck. my question is if i put this skinnyer tires on will it cause handling problems and or is it safe ? i would like to use these tires to save some cash but i want it to be safe in the snow and ice especially since i will be hauling around my newborn. i measured an they are about an inch and a half skinnyer.
