My Motorsport Edition has a spare “temporary use” wheel that is exactly the same as the one fitted on the front axle (same rim & tyre). The only difference is the spare has a speed warning sticker, a temporary wheel sticker and no TPMS sensor fitted.
Yes using the spare wheel on the back axle where the factory wheels are wider can cause a handling issue if one drives at 11/10 (=like an idiot)
But using that spare wheel on the front will make no difference to handling (unless one tire is near bald while the spare is near new and you’re driving in the wet)
