Tire Tread and the Useful Penny Test

Anyone who drives a car knows what tire tread is. But do you know how to tell whether it ’ s wearing slender ?
Worn out tires affect your car ’ s performance and your safety. fortunately, there ’ s a childlike way to check your tires with merely your scoop change .

Measuring Tread Depth With the Penny Test

A modern cable car tire typically has a tread astuteness of 10⁄32 or 11⁄32 inches while a ignite truck will have between 11⁄32 and 19⁄32 inches. The U.S. Department of Transportation recommends that you replace your tires once they ’ ve worn down to 2⁄32 inches. many states require tires to be replaced when the tread reaches that depth .
How do you know when your tires are officially worn out ? You can use a tread astuteness gauge or take your car in for a professional evaluation. But the easiest room is to do a penny test.

1. Take a penny and place it with Lincoln’s head upside down between two ribs on your tire.
2. If part of the head is covered, your tires are still in good shape.
3. If you can see his entire head, your tread is worn to 2⁄32 inch or less and it’s time for new tires.
4. Check various points on the tire — around the circumference and between different ribs — to look for uneven tire wear.

many car and truck tires come with indicator bars at 2⁄32 inch. If these are even with your step rib, you ’ ll know your tires need to be replaced .
now you can measure your tread, but you may not know about all its components or what unlike tread patterns are for. The more you know about types of tread, the easier it will be for you to choose the best tires for your fomite. hera are some facts to beef up your tire cognition .

What Is Tire Tread?

There are four ( sometimes five ) main components to tire pace :

1. Ribs: The long, raised bands that go all the way around a tire.
2. Blocks or lugs: The raised segments between ribs.
3. Grooves: The space between ribs.
4. Voids: The space between tread blocks.
5. Sipes (sometimes): Thin slits cut across the tread blocks and ribs.

Ribs and tread blocks make contact with the sidewalk, while grooves and voids channel water when roads are besotted and allow the blocks to flex as tires grip the road .
Siping is designed to improve tire operation during wet and winter drive conditions.

Different tire manufacturers combine these features to create signature designs and offer estimable operation for a crop of driving conditions .

Types of Tire Tread Patterns

Though each run down manufacturer makes singular variations on run down pace, the patterns by and large fall into three categories. Each traffic pattern provides different manage and operation .

1. Symmetric designs, as the name suggests, have the same pattern across the whole tire. This is the most common tread pattern for passenger cars.
2. Directional tread patterns include lateral voids pointing in only one direction, making a V design, and are used on performance cars (those designed for speed). These tires channel water in one direction for reliable handling in wet conditions and provide zippy handling on dry roads.
3. Asymmetric designs combine the above two patterns to offer good grip on dry roads as well as traction in wet and winter conditions. The inner side of the tire often features lateral voids like those found in directional tires, while the outer side uses larger tread blocks.

Summer tires and winter tires both generally have a symmetrical design, with winter tires sporting profoundly tread depth and sipes. Asymmetric patterns are frequently a good choice for all-season tires .

Safety Risks of Worn Tires

Though tires are considered bald at 2⁄32 inch, they lose some of their performance capabilities before that .
As run down tread wears, it becomes less able to channel water and the risk of hydroplaning increases, specially at higher speeds. If you know your tires are partially worn, be sure to give yourself extra stopping distance in wet conditions.

Grip loss on snow-white or icy roads is a concern. As the condom wears, sipes disappear and tread blocks do n’t provide as much bag. Again, allow yourself more stop distance and consider replacing your tires to stay safe during winter months .
Tires with partially worn tread are more likely to get punctures and lose air coerce, besides. And punctures can cause tire failure, which is a particular problem at high speeds because you can lose command of your fomite .

Drive on Safely

A penny test will tell you when your tires are bald, but if you ’ re headed into winter or a showery season, a pace depth gauge is the sure way to test. Or stop by your local tire shop to have a professional measure your tires .
