Every purchase at Fountain Tire is backed by our National Limited Warranty, also known as the Road Ready Protection Plan. It’s designed to give you confidence in your tires and the services we provide.
Tire Warranty Highlights
- Our Customer Satisfaction Guarantee means you can return or exchange your tires within 30–60 days, depending on the brand, if you’re not completely happy.
- Enjoy free tire rotations every 10,000 km to promote even wear and extend tire life.
- Road Hazard Protection covers unexpected damage from things like potholes, nails, and debris for up to 5 years, or until the tire wears down to 2/32" tread depth. A small processing fee and service charges may apply.
Mechanical Warranty Highlights
- Repairs completed at Fountain Tire are covered for 12 months or 20,000 km, whichever comes first.
- This includes most major systems: brakes, steering, suspension, heating and cooling, fuel and ignition systems, and more.
The warranty applies to the original purchaser only, and most claims must be reported within 30 days of the issue. If you're over 40 km away from your original store, coverage may still apply at another Fountain Tire or participating Goodyear Tire & Service Network location with prior approval.
