Default 7" wheel one side, 7.5" other side??

i have a set of wheels that are 17x7. i ruined one after a 'spirited encounter' with a curb

i have located a replacement of same style, diameter, and offset but the width is 7.5

do i run any chance of damaging my differentials by running a wheel a half inch wider on one side of the car?

i can't imagine so but i wanted to get some input before proceding...

Well, it'd require more torque to spin the wider(heavier) wheel, so the diffs would be working even when you're driving in a straight line. It might not be significantly more wear, but I wouldn't recommend it.

Also, you need to consider driveability. I'm not sure what effect running like that would have, but I can't imagine it would be anything but negative. If you're insistent on running different width rims, try and get a pair of them. You want the drivetrain to be balanced left to right.

I would maybe try to get the wheel repaired if possible.

Not sure if your diffs will get damaged, but you might have some pulling or tracking problems. Wheel width affects tire width, even if they're the same size tires, so one might have a bigger footprint than the other 3. Also if they're all the same offset but one is 1/2" wider, that might have an effect too.
