Wont that raise my unsprung weight and tire width?
the comparable upgrade to 14 I found was 185/60/14 with a .09% difference in spedo but it would add 1.10" or so to my width which may cause more drag and resistance? I may just stick and downgrade from the 175/70/13 back to the OEM recommended 155/80/13. the tire I have on there right now the 175/70/13 is .78" wider then the stock 155 so I may get some MPG and resistance improvements from going to a 155 tire. I know a thicker sidewall height is not always best for saving on resistance but can a wider heavier wheel save me gas if the tire that fits on it is better?
