Spring Tire Changeover Checklist for Canadian Drivers (2026)

Every spring, I watch people make the same mistake: they get one warm week in March and immediately pull their winter tires off. Then it snows again in April — because this is Canada — and they're driving on all-season tires in freezing slop.

Don't be that person.

Here's the complete spring changeover checklist from someone who's been in the Canadian tire business long enough to have seen every version of this mistake. I'll tell you exactly when to swap, what to look for when the tires come off, how to store them properly, and what it costs.

When Is It Actually Safe to Swap Winter Tires in Ontario?

The rule of thumb is 7°C consistently. Not one warm afternoon. Not a forecast that shows 10°C on Wednesday. Consistently above 7°C — meaning overnight lows are holding above freezing and daytime temperatures are reliably above 7°C for several days in a row.

Why 7°C? That's the temperature threshold where winter tire compounds start losing their advantage. Winter tires are made from a softer rubber compound that stays pliable in cold temperatures, giving you grip on snow and ice. Above 7°C, that same soft compound wears faster on warm pavement, and your all-season tires actually perform better.

In Ontario, that typically means:

• Toronto/GTA: mid-April to early May
• Ottawa/Eastern Ontario: late April to mid-May
• Northern Ontario: May, sometimes late May

Check Environment Canada's 14-day forecast for your area. When you see overnight lows consistently above 2–3°C and daytime highs in the 8–12°C range, it's time to book your changeover.

Quebec vs. Ontario: What the Law Says

Quebec drivers have no choice — winter tires with the snowflake symbol are legally mandatory from December 1 to March 15. No exceptions. Get pulled over without them and you're facing a fine up to $300.

Ontario has no such law. It's a recommendation, not a requirement. But "optional" doesn't mean unnecessary — if you're driving on Ontario roads in January without winter tires, you're taking a real risk with your safety and your insurance coverage. Some Ontario insurers offer a discount for winter tire use. Check your policy.

Step-by-Step Spring Changeover Process

Option 1: Book a Shop

Most shops in Ontario charge $60–$120 for a seasonal tire changeover, which includes removing your winter tires and wheels, mounting and balancing your summer or all-season tires, and torquing the lug nuts to spec.

If you're running a dedicated winter wheel setup (separate wheels for winters), the changeover is cheaper and faster because there's no mounting and balancing involved — just a wheel swap. That usually runs $40–$60.

Book early. Late April and early May are slammed at every tire shop in Ontario. The moment the forecast shows a warm stretch, every shop gets flooded with calls. If you wait until mid-April, you might wait 2–3 weeks for an appointment.

Option 2: DIY Swap

If you have a jack, jack stands, and a torque wrench, you can do a seasonal wheel swap yourself in about 30–45 minutes. There's no mounting or balancing if you're switching between dedicated wheel setups.

Here's the basic process:

1. Loosen lug nuts before lifting the vehicle
2. Lift vehicle and support on jack stands — never work under a car on just a floor jack
3. Remove winter wheel, set aside
4. Mount summer/all-season wheel, hand-tighten lug nuts in a star pattern
5. Lower vehicle to ground, torque lug nuts to spec (check your owner's manual — usually 100–140 Nm for passenger cars)
6. Repeat for all four corners
7. Check tire pressure on all four tires — adjust to the door placard spec

One important note: if you have a TPMS (tire pressure monitoring system), you may need to reset it after the changeover. Some vehicles do this automatically after driving for a few minutes; others require a manual reset procedure. See the TPMS reset guide for details specific to your vehicle.

What to Inspect When Winter Tires Come Off

This is the step most people skip entirely. When your winter tires are off the car, you have a perfect opportunity to inspect them before storing them. Takes 10 minutes. Could save you from an unpleasant surprise next fall.

Tread Depth

Measure with a tread depth gauge (they cost about $10 at any auto parts store). Winter tires should be replaced at 4/32" (3.2mm) — not the legal minimum of 2/32", but the winter performance minimum. Below 4/32", winter tires lose significant traction in snow.

The penny test works in a pinch: insert a penny with Queen Elizabeth's head pointing down into the tread groove. If you can see the top of her head, you're below 4/32" and those tires are done for winter use.

Grade each tire: If one or two corners are significantly more worn than the others, that tells you something about your alignment, inflation habits, or driving style that's worth addressing.

Sidewall Inspection

Look for:

• Cracks — Small surface cracks from ozone exposure are common and usually cosmetic on newer tires. Deep cracks that extend into the tread grooves are a problem.
• Sidewall bulge or bubble — This is a structural failure. A bulge means the internal belt has separated. Replace immediately.
• Cuts or gouges — From curb strikes or road debris. Small surface cuts are usually fine; anything that penetrates into the cords is a replacement candidate.

Uneven Wear Patterns

If you see significant uneven wear, get an alignment check before mounting the summer tires. Putting new tires on a misaligned vehicle is throwing money away.

Should You Rotate Tires at Changeover?

Yes. Absolutely yes.

Tires wear at different rates depending on their position. Front tires on a front-wheel-drive car typically wear faster than rears. Rotating at changeover — moving fronts to rear, rears to front — evens out this wear and extends the life of your tire set by 20–30%.

The standard rotation for most vehicles:

• Front-wheel drive: Front tires straight back, rear tires crossed to the front
• Rear-wheel drive: Rear tires straight forward, front tires crossed to the rear
• All-wheel drive: X-pattern (crossing all four)

If your tires are directional (marked with an arrow on the sidewall), they can only be rotated front-to-rear on the same side — they can't be crossed.

Tire Storage Best Practices

Storing your winter tires properly makes a real difference in how long they last. Tires stored poorly show premature cracking and compound degradation.

The Right Way to Store Tires

• Clean before storing: Wash with soap and water to remove salt, brake dust, and road grime. Let them dry completely before storing.
• Store in a cool, dark location: Heat and UV light degrade rubber. A basement, attached garage, or climate-controlled storage area is ideal. Avoid outdoor storage in direct sunlight.
• Keep away from ozone sources: Electric motors, furnaces, and fluorescent lights generate ozone, which accelerates rubber cracking. Don't store tires next to the furnace or hot water heater.
• Use tire bags: These are inexpensive (about $15 for a set of four) and significantly reduce ozone exposure during storage. Garbage bags work in a pinch — just avoid airtight sealing.
• Stack horizontally or hang vertically: If storing tires mounted on rims, stack them horizontally (no more than four high) or hang them on a tire rack. Unmounted tires should be stored standing upright.
• Don't store near solvents or lubricants: These can leach into the rubber and cause degradation.

Tire Storage Rack vs. Bags

A wall-mounted tire storage rack costs $40–$80 and keeps your tires off the floor, organized, and in good condition. If you're storing two sets of tires every year, it's worth the investment. Saves floor space in the garage and prevents the hassle of stacking and unstacking.

Cost Breakdown: Spring Changeover in Ontario

Here's what a typical spring changeover costs at an Ontario tire shop in 2026:

Prices vary by shop, location, and tire size. Performance tires (larger diameters) and low-profile tires cost more to mount and balance due to the extra care required.

Planning Ahead for Next Fall

While your winter tires are off and you're inspecting them, take a few minutes to think about fall. If your winters are at or near the end of their useful life, now is actually a good time to buy replacements. Off-season pricing is better, availability is better, and you won't be scrambling in October when every shop in Ontario is booked solid.

If you're running your winter tires on your summer rims (a common mistake that costs you in mounting fees every year), consider picking up a dedicated set of steel wheels for next winter. The investment pays for itself within two seasons.

And if you're running the same tire size year-round, look into downsizing your winter wheel setup — a smaller diameter winter wheel with a taller tire gives you better snow performance and cheaper winter tire options.

The Changeover Checklist Summary

Print this off and bring it to your shop or stick it on the garage wall:

• Confirm 7°C+ temperatures consistently before booking
• Book appointment in advance (don't wait for the rush)
• Check TPMS sensors before/after swap
• Inspect tread depth on all four winter tires (minimum 4/32" for next winter use)
• Check sidewalls for cracks, bulges, or damage
• Note any uneven wear patterns (book alignment if needed)
• Rotate tires at changeover
• Clean tires before storage
• Store in cool, dark, dry location away from ozone sources
• Note condition in your phone — don't find out next October they're done

Getting your changeover done right takes an hour. Getting it wrong can cost you a set of tires or, worse, a dangerous situation on the road. Take the time to do it properly.
