What is the 3% rule for tires?
As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle. 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.It’s highly recommended to use the exact tire size recommended for your car. However, in a pinch the tire width and aspect ratio can be changed slightly and still fit on your rim. Although this will still work, keep in mind it may have adverse effects on the performance of your car.
Are bigger tires better?
Simply put, the larger your tire, the more of a grip your vehicle has on the road. As a tire’s width increases, it covers more surface area on the road. Many drivers give little thought to the sizes of their wheels and tires except for cosmetic purposes. But, wheel size — and the size of tires you put on them — matter. larger tires require more energy from the engine to move the vehicle compared to smaller tires, resulting in increased fuel consumption. Smaller tires and wheels demand less engine output, making them more suitable for navigating stop-and-go city traffic efficiently. Larger and heavier tires do offer advantages.
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. Winter tires perform best at 7 degrees Celsius or below In cold weather, harder compounds become even stiffer, reducing grip and traction on cold pavement (which also hardens). Below 7 degrees Celsius, winter tires offer noticeably better control, whereas summer tires can feel like “ice skates” on icy roads.
