Warranty Info
Prorated Tread Wear Warranty
We offer warranty that is based on how much you have used the tire. It protects you against the tire wearing out early. This warranty does not have a time limit.
If warranty is purchased, tires sold by True North Tires will include a prorated tread wear warranty. It provides credit toward a replacement tire if your tire wears out early under normal driving conditions. This includes damage from road hazards.
Coverage applies only to tires purchased through TrueNorthTires.ca. The warranty is valid until the tread wears down to 2/32”, and only if the warranty was purchased with the tires.
To calculate your credit, we use this formula:
(Remaining Tread ÷ Usable Tread) × Current List Price
- Original tread depth: 10/32”
- Minimum legal tread: 2/32”
- Usable tread: 8/32”
Example 1:
If you have 4/32” of tread left and the current list price is $100, the credit would be:
(4 ÷ 8) × 100 = $50
This means you’d get $50 toward a replacement tire.
In other words, if you still have half your usable tread, you’ll get half off a new tire.
Example 2:
If you’ve only used 2/32” of tread (meaning you have 8/32” remaining), and the current list price is $100, the credit would be:
(8 ÷ 8) × 100 = $100
This means you’d get 100% credit - a free replacement - because you’ve barely used the tread.
This warranty does not cover improper inflation or alignment, cosmetic wear, or normal aging. It also does not cover installation, balancing, taxes, or disposal fees.
To make a claim:
- Measure the remaining tread
- Take clear, dated photos
- Include proof of purchase
- Email all documents to info@truenorthtires.ca
