Switching from Winter to Summer Tires: When and How to Do It Properly
Published on March 19th, 2025
Spring is just around the corner in Quebec, and with it comes the recurring question: when is it time to switch from winter tires to summer tires? Contrary to what some may think, a warm 15-degree afternoon in March doesn’t necessarily mean it’s safe to make the change right away. Transitioning between tires should be carefully planned to ensure your safety and extend the lifespan of your tires.
When should you change from winter to summer tires?
In Quebec, the law requires drivers to keep their winter tires on until March 15. After that date, it becomes legal to switch to summer or all-season tires. However, just because you can change your tires immediately doesn’t always mean you should.
The right time to make the switch is when temperatures consistently stay above 7°C, both during the day and at night. Below this threshold, summer tires lose effectiveness because their rubber hardens in the cold, reducing traction and increasing braking distances. For this reason, it’s best to wait a few weeks after March 15—especially if colder nights or late-season snowfalls are still in the forecast.
What about studded tires?
If you use studded winter tires, Quebec law requires that you remove them before May 1. Driving with studs on dry, clear pavement not only damages the road surface but also reduces their efficiency for the following winter. Removing them early helps preserve their condition and performance.
Why not keep winter tires in summer?
Some drivers wonder if it’s truly necessary to invest in summer tires or if they can simply keep using their winter tires year-round. While technically possible, driving with winter tires in summer is not recommended for several reasons:
Premature tire wear
Winter tires are designed to stay flexible in freezing conditions. In summer, the heat makes their rubber even softer, causing them to wear down quickly. Within just a few months, a set of winter tires can lose much of its performance, shortening its lifespan.
Reduced performance and safety
Winter tires are optimized for snow, ice, and cold temperatures. On dry, hot pavement, they don’t provide the same grip as summer tires. This increases braking distances and reduces steering precision, which can be dangerous in emergency situations.
Risk of tire blowouts
Another underestimated risk is tire blowouts. The soft rubber of winter tires combined with high summer temperatures can cause overheating, weakening the tire’s structure. At high speeds or during sudden braking, this can lead to deformation or even a blowout—putting your safety at risk.
Increased fuel consumption
Winter tires have higher rolling resistance compared to summer or all-season tires. This means your engine needs to work harder, which results in higher fuel consumption. Over several months, this can represent a significant additional cost.

How to properly store your winter tires
Once your winter tires are removed, proper storage is essential to maintain their condition and extend their lifespan. Start by thoroughly cleaning the tires with soap and water to remove any salt, dirt, or road debris that could accelerate wear or damage. While cleaning, take the opportunity to inspect each tire carefully, checking the tread depth and looking for any cracks, cuts, or deformations that might affect their performance next season.
The storage location is just as important. Tires should be kept in a cool, dry place, away from direct sunlight and sources of heat. A climate-controlled garage or basement is ideal, whereas outdoor sheds or areas subject to extreme temperature changes should be avoided. Proper positioning also helps prevent damage over time. Tires mounted on rims can be stacked horizontally or suspended, while tires not mounted should be stored standing upright and gently rotated occasionally to avoid developing flat spots.
By taking these precautions, you ensure that your winter tires remain in good condition, ready to provide safe and reliable performance when the cold season returns. Proper cleaning, inspection, and storage will not only extend the life of your tires but also protect your investment and enhance your vehicle’s safety on the road.
Patience pays off
Switching from winter to summer tires at the right time is essential for both your safety and your vehicle’s performance. Wait until temperatures remain consistently above 7°C before making the change, and store your winter tires properly so they’re ready for next season.
While a few warm days in March or April may tempt you to install summer tires early, it’s worth being patient and making sure conditions are truly favorable. Both your tires and your wallet will thank you!
