For example, let’s look at 11R22. In this example, the information includes: 11 = Section width in inches. R = Radial Tire. Rim diameter and rim type. R” stands for the construction method of the tire indicating the tire is a radial tire. The following two numbers (16) indicate the diameter of the wheel rim in inches.For example, let’s look at 11R22. In this example, the information includes: 11 = Section width in inches. R = Radial Tire. Rim diameter and rim type.
What is the 7’7 rule for winter 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 lose their effectiveness as temperatures rise. Designed with a soft, flexible composition ideal for icy conditions, they perform poorly on warm asphalt. Their tread patterns are optimized for snow and ice and can reduce traction on rainy surfaces, particularly at higher speeds.Don’t let winter slow you down—20 inch snow tires give you the best grip to tackle any snow challenge. Their deep treads and flexible rubber compound perform well on icy and snowy roads.It is NOT recommended to use winter tires in summer or hot weather conditions. They are made with rubber compounds that keep the tires flexible and provide traction, even in temperatures below 45°F (or 7°C).The special rubber compound that makes them flexible in freezing temperatures also makes them wear out much faster in warmer weather. Plus, the higher rolling resistance of the deeper tread means you’ll reduce your MPG, spending more on gas.
Do you need 2 or 4 snow tires?
When driving in winter conditions, including ice and snow, staying in control and on the road is the top priority that starts with equal traction on all four tires. Installing snow tires on just the front or back of your vehicle won’t do the job, and could put you and your family in danger. You’ll Have to Replace Them Sooner Winter tires wear out fast on hot pavement. The rubber is soft (on purpose), so in summer it breaks down quicker. You’ll likely get one or two fewer seasons out of them if you leave them on all year.Snow Tires (Older Term): First designed mainly for deep snow traction. They had chunky tread patterns that worked in snow but were less effective on ice, wet roads, or cold, dry pavement. Winter Tires (Modern Term): Built for all cold-weather conditions, like snow, ice, slush, rain, and frozen pavement.Nonetheless, the recommended time to switch over to Winter Tires should be late September to early November.Cons: Wear and Tear: Winter tires aren’t ideal for higher temperatures and dry roads. This doesn’t mean that winter tires don’t work during seasons other than winter, but it does mean that winter tires will wear out faster under normal conditions.
