Ask what qualifies

Insurers can define documentation, dates or tire requirements within approved programs.

Do not buy tires solely for an insurance discount

Winter tires are primarily a driving-safety and seasonal-traction decision.

Keep purchase records

Receipts may help if an insurer requests proof.

Recheck renewal documents

Discount coding can sometimes need updating after vehicle or insurer changes.
