Searching for
What Calgary drivers should know before buying tires online — sizes, seasons, specs, and booking install.
Use our tire finder to search by sidewall size, vehicle or VIN, or brand — then refine on the results page.
Enter width, aspect ratio, and rim size, or paste a full size like 225/60R17. You will land on tire results filtered to that fitment.
Your VIN or year, make, model, and trim helps us show factory tire sizes for your vehicle. Results depend on what we have in stock and published online for your sizes — not every trim will show matches.
Saved vehicles in Your vehicles speed up repeat searches when you are signed in.
Browse tires by manufacturer, then narrow by size and filters on the results page.
Numbers like 225/60R17 102H — width, aspect ratio, rim diameter, then load index and speed rating.
Factory size sticker on the pillar when you open the driver door.
17 characters on registration, insurance, or the base of the windshield (driver side).
Softer rubber compounds and tread patterns designed for cold temperatures, snow, and ice. For Calgary winters, dedicated winter tires are strongly recommended for safety — Alberta does not require them by law, but they perform better than all-season tires below about 7 °C.
A compromise for year-round driving in milder conditions. They trade some cold-weather grip and snow performance for convenience if you drive mostly on cleared roads.
Optimized for warm, dry, and wet pavement. Not intended for winter use. Best when you run a dedicated winter set for the cold months.
After you search, use filters on tire results and product pages to compare options. Definitions below match what you will see at Spec R.
Primary filters also include Brand, Season, Speed rating, Vehicle type, Price, and In stock only. Try filters on sample results →
Side-by-side specs and pricing before you buy. Use brand, season, UTQG, rebates, and more on the results page.
Some tires qualify for manufacturer mail-in rebates. When a campaign is active, you will see a rebate badge on results and product pages. Rebates are optional offers — not every tire has one. Sort results by rebate first to surface eligible products.
Turn on In stock only to hide unavailable sizes. Use the price range filter to stay within budget. Share or bookmark your filtered results — the URL updates as you filter.

Calgary winters drop well below freezing — often near −30 °C — with Chinook warm-ups in between. Dedicated winter tires stay flexible in the cold; switch near 7 °C when sustained cold arrives.
Alberta allows studded passenger tires October 1 through April 30 on most roadways, including Calgary, unless posted otherwise. Studless winters suit many city drivers; studded options help on hard-packed ice.
BMW M models, Porsche, and many performance sedans use different front and rear tire sizes. Search by vehicle in our tire finder to see staggered OEM sizes on results — shop front and rear together when both are in Alberta inventory.
Use size when you already know the numbers on your sidewall or door jamb sticker. Use vehicle or VIN when you want factory sizes for your trim without looking them up. Either path leads to tire results where you can filter further.
Winter tires are not legally required in Alberta, but they provide much better grip in cold, snow, and ice than all-season or summer tires. Many Calgary drivers run a dedicated winter set from late fall through spring.
Vehicle search shows tires that match your OEM sizes and are published to our online store. If nothing appears, try searching by size directly, contact us, or check back after new inventory is synced.
Add up to four tires from results or product pages, then open Compare tires to see specs and pricing side by side.
Rebates are manufacturer mail-in offers on select tires during active campaigns. Follow the rebate link or instructions on the product page. Eligibility and amounts are set by the manufacturer, not Spec R.
Yes. Add tires to your cart and checkout online, then use Book installation to schedule mount and balance at our Calgary location.
It is a mandatory provincial environmental fee on tire sales in Alberta, collected by retailers and remitted to fund tire collection and recycling programs (Alberta’s tire stewardship system). It is not part of the tire’s listed price — at Spec R it is added at checkout, usually $5.0 per passenger or light-truck tire (amounts can differ for other tire categories per the official schedule).
In your cart it appears as a separate line (often labeled as a government environmental fee) in addition to the tires you are buying. See the Alberta Recycling tire fee schedule for full details.
