How can we help?

Three reliable ways to confirm your tire size:

• Owner's manual — manufacturer-recommended size and load rating.
• Sidewall of current tires — printed in the format 225/55R17 91V.
• Online tire size finder — search by year, make, model, and trim on our tire finder.

Your driver's door jamb sticker also lists the OEM-recommended size and pressure.

Take a size like 225/55R17 91V:

• 225 — section width in millimeters
• 55 — aspect ratio (sidewall as % of width)
• R — radial construction
• 17 — wheel diameter in inches
• 91 — load index (max weight per tire)
• V — speed rating (max sustained speed)

We strongly recommend sticking to the manufacturer-recommended size. Different sizes can affect handling, speedometer accuracy, all-wheel-drive systems, and may impact insurance or warranty coverage. If you want to change size for performance reasons, consult our tire size guides first.

If average winter temperatures in your area drop below 45°F (7°C) or you regularly drive on snow, dedicated winter tires (look for the 3PMSF mountain-snowflake symbol) provide significantly better grip and shorter stopping distances than all-seasons. In milder climates, a quality all-season tire is enough.

The Z is a speed rating — it indicates the tire is rated for sustained speeds above 149 mph (240 km/h). Z-rated tires use stiffer sidewalls and grippier compounds for sharper handling, but typically wear faster. Read the full comparison →

Unmounted tires can be returned within 30 days of delivery for a full refund. Tires must be in their original, unused condition. Once mounted on a wheel, tires can only be returned under warranty. See our full Refund Policy for details.

Every new tire is covered by the manufacturer's treadwear warranty (typically 30,000–80,000 miles depending on model) and a materials and workmanship warranty against defects. Coverage details ship with the tire and are listed on the product page.

Contact us within 7 days of delivery with photos of the damage and packaging. We'll arrange a replacement or full refund at no cost to you.

Yes — optional road-hazard coverage is available on most tires for a small per-tire fee at checkout. It covers repair or replacement for non-repairable damage from potholes, nails, glass, and other road debris during normal driving.

From your account, open the order and select Request Return. Or contact our support team. Refunds are processed back to the original payment method within 5–10 business days of receiving the returned tires.
