This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy.

The same goes for using summer or all-season tires in snow and ice. Winter rubber compounds get too soft in warm temperatures, leading to excessive wear, reduced grip, and increased stopping distances.As winter ends and temperatures steadily rise, it’s time to replace your winter tires with all-season or summer tires. At Les Schwab, we recommend swapping back to your all-season or summer tires when nighttime temperatures are consistently 50º F or when you do not plan to drive on snow or ice-covered roads.However, regular tires are not optimized for cold weather and slippery conditions, and they tend to lose traction and grip when the temperature drops below 45°F.

From low pressure to hidden damage, post-snow inspections are essential to avoid accidents and breakdowns. Addressing common tire problems early not only improves safety but also extends tire life and enhances winter driving performance.Running winter tires outside of the extremely cold months is just throwing money down the drain. They’re also tough on the roads – the deep biting treads will do the same thing to smooth asphalt as they do to smooth ice, and wear down the roads. Finally, they don’t offer great handling.
What are considered snow tires?
What Are Snow Tires? Winter or snow tires are designed for prolonged winter conditions, including snow, ice, and slush. The tread compounds in those tires stay softer and more flexible in cold weather. This improves traction, handling, and control when temperatures dip below ~45º F. How much are snow tires? You can expect to pay between $400 and $1,200 for a set of four tires, with prices varying depending on the tire type and size.On average, they are slightly more expensive than an equivalent summer tyre in the UK. However, while the cost of four winter tyres is significant – especially if you also buy a set of ‘winter wheels’ to avoid swapping over twice a year – remember that your summer tyres will last longer as a result.
