What is the 3% rule for tires?

What is the 7 7 rule for tires?
The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes. Install winter tires when daily temperatures drop to 7°C (45°F) or below for seven consecutive days. Remove them in spring after seven straight days above 7°C. If you leave them on too long, your winter tires will degrade quickly. So, when is the right time to swap? The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. The reverse is also true for transitioning to winter.

How much difference in tire size is acceptable?
Generally, you don’t want to go with tires that have a diameter that is more than 3% different from the factory tires. It’s also a good idea to consult with a trusted mechanic before switching to larger or smaller tires. Wrong-sized tires can put extra strain on your vehicle’s drivetrain, suspension, and braking systems. If the tires are too large, they may rub against the wheel wells or fenders, damaging both the tire and the vehicle body.Likewise, it is advised you stick within the 1. Incorrect tyre sizing can cause damage to the car. Bigger rims, or wider tyres, will make contact with the wheel arch, causing excess wear and tear, as well as more difficult driving.Many people believe that wider tires are better for a car’s handling. However, there are some drawbacks to using wide tires. One of the most significant problems is that they can cause slower acceleration and harder steering. This is because wider tires have more contact with the road, which creates more friction.
