I have a Honda Integra 2002 sedan automatic

Hit a rock and tyre front left went flat, changed it temporarily to the space-saver wheel (yellow baby wheel )

Driving home about 20klms - getting a rubbing groaning noise on take off from standing start or kicking down gears (wasn't making that noise before space saver went on)

Changed flat tyre and other front right tyre with two new front tyres next day

Still getting that rubbing groaning noise after the tyres were changed. Troubling!

Does this mean that I have done in the differential or some other damage as well?

The penny dropped that the space saver wheel might not have been the same circumference as the front wheel on the other side and caused diiff wear or damage??

Any thoughts

If so, is this an expensive fix?
