How to save money and nerves when changing tires

Whether it’s Easter or October, a bit before or a bit after – during this period, your tyres need to be changed. The rule says Easter to October, and here are a few things you should definitely keep in mind.

Why do tyres need to be changed?

Every tyre is made of rubber, and rubber reacts to weather conditions. That’s why, for hot and stormy summer days, you need a hard rubber compound for better grip. In winter, on cold and snowy roads, a softer compound is required for better traction.

Technically, you can drive with winter tyres all year long without a major safety issue. However, fuel consumption increases significantly as the weather warms up. And if you drive on winter tyres year-round, you'll definitely need to buy new ones by the next October due to increased wear. So switching to summer tyres also saves you money!

Are there all-season tyres?

Yes, there are all-season tyres. But the technology isn’t quite there yet – studies show that no matter which model, all-season tyres never achieve the same safety performance as season-specific tyres.

Timing – When should you change your tyres?

In the German-speaking part of Switzerland, the memory aid “O to O” (Ostern to Oktober) is widely known when it comes to changing tyres. Easter for summer tyres, October for winter tyres. Since this rule doesn’t work in every Swiss language, a standard guideline is to switch when the night temperatures consistently exceed 7°C.

For Carvolution customers, the change is super easy. You’ll find all the details in our blog.

Quality and safety – When do I need new tyres?

It takes quite a bit for tyres to wear out. Factors like extreme temperature changes, driving behaviour, and road conditions all play a role.

You can check if your tyres are still good for another season by measuring the tread depth. There’s a small tool you can use by placing it in the grooves to read the remaining millimetres.

In Switzerland, tyres must be replaced if:

Recommended replacement at:

• Tread depth for summer tyres = 3 mm

• Tread depth for winter tyres = 4 mm

Minimum tread depth – Immediate replacement required!

• Summer tyres = 1.6 mm

• Winter tyres = 1.6 mm

Tyre pressure should also be checked and adjusted regularly. You can do this easily at any petrol station. There’s no universal bar value, as it depends on your car’s size and weight. The correct pressure is listed on a sticker in the door frame or inside the fuel cap.
