MPI's Winter Tire Program finances eligible winter tires and related costs. Tires must carry the 3PMSF symbol. Effective October 1, 2026, eligible tires must also be designated and marketed solely for winter use; all-weather, all-season, four-season, and year-round tires will no longer qualify, even if they carry 3PMSF. MPI low-interest winter tire financing is available to eligible Manitobans.

Winnipeg winter tire questions

Book the swap a week or two ahead; shops fill up after the first cold snap.
When do winter tires come off in Winnipeg?
After April 26, when mean daily temperatures climb back above 7 C to stay. Taking them off earlier risks a late cold snap; much later wears the soft compound on warm pavement.
Is there a winter tire law in Manitoba?
No general winter-tire mandate; MPI financing is available for eligible dedicated winter tires. MPI low-interest winter tire financing is available to eligible Manitobans. Source: Manitoba Public Insurance, verified 2026-09-27.
