However, some spare tires (space-saver and donut types) are not meant to be driven long distances. Space-savers have a maximum speed of around 50 mph (80 km/h). When replacing a damaged tire, placing the compact spare on a non-drive axle will prevent damage to the drivetrain. If placed on a drivetrain axle, the smaller-diameter tire can put stress on the differential causing damage and reducing handling.
