I got a flat the other day, and found 2 tires in my garage. The problem is , they are not the same size as the front tires I have on now. I am currently running 195/60/R14 in the front, and put 185/70/R14 on the rear. The question is what negative affects will this have on the tires, being mismatched, and what affects on the car in general. Will my gas mileage go down? Please chime in with some info. Thank you.

 

the problem would be if the front pair didn't match or the back pair, but there shouldn't be a big problem with that set up, i am currently running 205 front and 195 rear, no problems

 

yeah i got 195 in back and 205 up front so it dosen't really matter unless your mismatching say the LEFT if different then the RIGHT but other wise it should be okay
