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. Ultra-high-performance all-season tires offer a compromise between summer tire performance and all-season versatility. They provide a good balance of grip in various conditions, including light snow. They may not match the peak performance of uhp summer tires in dry or wet conditions.When you’re on bare or wet pavement, the right set of all-season tires is designed to keep you safely on the road. They even do okay in mild winter conditions. But when the weather worsens and roads are covered in ice and snow, having the right set of winter or snow tires can help you stay in control of your vehicle.All-season tyre efficiency While all season tyres might not match the fuel efficiency of dedicated summer tyres, they provide a good middle ground. They perform well in most conditions, allowing for better handling and braking on both warm and cold roads without the need for seasonal changes.Fuel consumption – as all season tyres are not optimized for warm weather driving, they do not perform as efficiently on dry roads compared to summer tyres. Performance on icy roads – whilst all season tyres are better for driving on snow or ice than summer tyres, they do not perform as well as winter tyres.Rubber: Winter tires are made with a special rubber compound that stays flexible in temperatures below 45º F. This means those tires can grip the snow and road better. In contrast, all-season tires can become rigid in colder temperatures, reducing grip on the road.
Which tire is taller, 60 or 70?
If a tire has an aspect ratio of 70, it means the tire’s height is 70% of its width. Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series, but a typical trade off can be ride harshness. R16 has a 70% aspect ratio, which gives a shorter sidewall than the 265/75R16. The diameter is about 30. The 265/75R16 has an aspect ratio of 75% which gives a taller and wider sidewall as compared to the 265/70R16 tire and an overall diameter of approximately 31.
