Questions we get asked

How do I know what size I need?
Read it off the sidewall of the tire on your vehicle right now — it looks like 225/65R17. Match that exactly. If you are changing sizes, talk to us first; the wrong diameter throws out your speedometer.

Do you install and balance?
Yes, in-house at our Edmonton shop, including TPMS service. Tires bought here are mounted, balanced and torqued by us — book it when you order.

What does the number and letter after the size mean?
That is the load index and speed rating, for example 97W. The number is how much weight one tire can carry; the letter is its rated top speed. Both are listed on every tire page. If you tow, the load number is the one that matters.

Is a cheaper import tire safe?
Every tire we sell meets Canadian road-legal standards. The difference against a premium brand shows up in tread life and wet braking at the limit, not in basic safety.

Can I run these year-round?
No. Performance compounds harden below about +7°C and lose grip badly. These come off before the first snow — that is not a upsell, it is a safety point.
