Rim size

[classic67]

the oem tire size for an aveo with 15s is 195 15 so it shouldn't mess with the computer at all because all your doing is adding an inch on the wheels and subtracting an inch from the tires copared to the 14 in wheels and 185 60 14 tires. width has nothing to do with the computer

But then again, the 15" is like +-$100 cheaper (R1000 in south africa).
