For the regions of the US & Canada where winters are cold, vehicle owners typically purchase a second set of rims & tires, for vehicle travel during the colder months. Tires designed for colder weather allow for better traction during wintertime. A spare wheel set (rim, tire, valve & sensor) allows for easier installation for the seasonal change-over, as the OEM assemblies don’t have to disassembled in order to install winter/snow tires onto the rims.
Alligator sens.it sensors come with configurable identifiers, so the tire shops can copy the IDs from the OE sensors during installation. When cloning the original sensors, it’s possible to skip the relearn process when installing the new wheels, which is helpful for vehicle owners that change out the rims & tires themselves each season.
