Finnish drivers warned against using studless winter tyres in summer

Finnish drivers are being urged to replace studless winter tyres with summer tyres as the seasonal changeover approaches, despite the practice being legally permitted, Yle reports.

Autoklinikka, a national auto repair chain, has observed a concerning trend: more drivers are opting to keep their studless winter tyres—even new or well-maintained ones—throughout the summer months. “Some plan to wear out their old studless tyres over the summer, while others drive on brand-new ones,” said Marno Kelo, Autoklinikka’s operational manager for brand maintenance. In previous years, only a few sets of summer tyres went uninstalled, but in recent seasons, dozens have been left unchanged.

Teppo Vesalainen, training manager at the Finnish Automobile Association, called the trend alarming, noting that while cost-cutting is understandable, tyres are a dangerous area to scrimp. “Studless winter tyres behave unpredictably in summer, especially in sudden braking or evasive maneuvers,” he warned. The risk stems from longer stopping distances and compromised handling in emergencies.

Tero Mäkelä, service manager at Vianor’s Kankaanpää branch, confirmed that while few customers actually follow through with summer use of winter tyres, many consider it—until advised of the safety risks. “Once they understand the implications, they usually change their minds,” he said.

Experts also caution DIY tyre changers to use proper equipment and techniques, particularly with heavier electric vehicles. Vesalainen stressed that incorrect jack placement can damage battery housings, leading to costly repairs. “Assuming you know how isn’t enough,” he said.

The peak season for tyre changes is expected after Easter, though drivers are advised to monitor nighttime frost and weather conditions before switching. Finland’s varied climate means regional differences in optimal timing.
