I bought my 2002 mazda trubite(small SUV) a few months ago and went to rotate the tires and saw that the back tires are a little bigger than the front. I dont know why the person did this but would it be bad to put larger tires on the front? The back tires that would be on the front are 245 70R16 and the front tires to go the back are 235 70R16. You cant tell the tires are different sizes just looking at them. It is front wheel drive.
