can i put a space saver on a steer wheen

Yes, you can bolt a space-saver onto a steering (front) wheel, but it’s the limp-home option, not a lifestyle choice. Better practice: move a good rear wheel to the front, and fit the space-saver on the rear so steering and braking stay less grumpy. Obey the sticker—usually max 80 km/h—and keep trips short; grip, braking and ABS/ESC behaviour are all compromised. On AWD/4WD, mismatched rolling diameters can upset or damage the driveline, so check the owner’s manual before you get creative. Some cars also have front brake clearance issues with space-savers. Fix the proper tyre ASAP and treat the little donut like a house guest—you want it gone by the weekend.
