Ever wonder what the designations stamped on your tire sidewall actually mean? We’d like to break it down for you.
Let’s take for instance, “P195/60R15 87S”. This is a full service description of a tire.
In this case, “87S” denotes a tire’s load capacity and speed rating. The higher the number, the greater the load capacity – an 87 load capacity means that tire can support 1,201 pounds. Speed ratings range from L (75 mph) through V (149 mph), and an S speed rating means the tire is good for 112 mph. W, Y, and Z-speed rated tires are available for extreme performance cars and are rated as high as 186 mph.
As for the rest of the information:
--“P” denotes Passenger Tire
--195 is the tire’s width from si ...[more]
Every year, about 290 million tires are discarded; of those, about 233 million are recycled in one way or another. Shredded tires can be used for playground surfaces, welcome mats, hot-melt asphalt, bark mulch and even made into building material for “green” construction.
But what can you do with your old tires? Here are some ideas:
--Fill a tractor tire with sand to make a great sandbox for kids
--Hang a tire from a rope as a tire swing
--Stack a couple of tires on top of each other, bolt them together and paint them a cheerful color, then use them as a planter
--Lay two rows of tires next to each other, somewhat staggered, and use them for broken-field running as part of football conditioning
--Bolt two tires togeth ...[more]
Ever think about all the different vehicles that use rubber tires? Tractors, industrial equipment, everything else that rolls on rubber?
Each specialized type of tire requires a specialized design for its specific purpose. Aircraft tires, for instance, have to be very robust and handle a great deal of weight and stress, but for only a short period of time. Aircraft tires are often filled with an inert gas such as nitrogen, for more stable inflation levels, and are designed with specialized fusible plugs which provide a safer failure mode (rather than a sudden, catastrophic tire explosion).
Off-the-road tires, for vehicles such as graders or mining equipment, operate at low speeds but have to be able to withstand severe service conditions while ha ...[more]
Nobody ever looks forward to a flat tire, and nobody ever says "well, that was a really good time" after having one. You can at least minimize the damage to your tire and danger to yourself, though.
Flats vs Blowouts
If you get a blowout, you'll know about it right away. Sometimes the tire can fail dramatically, with a bang as loud as a shotgun going off. Other times, it might just be a loss of air and a sudden change in your car's handling, followed by vibration, noise and a pull to one side. If it's a front tire that fails, your car might be a real handful to drive until you can get to a stop.
In either case, your first job is to pull off the road as quickly (but safely!) as you can. Don't jam on the brakes or make any sudden mo ...[more]
When it comes to your car, oil isn't the only thing there's a finite supply of. Rubber has its limits too, and it's estimated by 2020, the supply of natural rubber in the world may be outstripped by demand. And of course, tires require a great deal of oil to produce as well. Tire manufacturers are constantly looking for ways to innovate and conserve resources in tire production. Here are some recent advances:
- Dandelions: Yes, those humble yellow flowers you try to eliminate from your yard. Dandelions actually contain a minute amount of latex in their milky oil, and research shows they can actually produce about as much latex, pound-for-pound, as rubber plants. German scientists have cultivated 1-foot-tall dandelions for just this purpose. This isn't a new development, either -- in WWII, Amer ...[more]
So your closet has a pair of flip-flops for the summer, a pair of heavy boots for the winter, and a comfortable pair of sneakers for most of the rest of the year. If you live in a climate that doesn’t have harsh winters, you might just be able to wear those sneakers year-round...and all-season tires are the equivalent of your comfortable sneakers.
So what makes all-season tires so special?
Winter tires are excellent for severe conditions like heavy snow and even ice. They feature specially-designed tread patterns and “sipes”, hundreds of tiny slits which offer biting edges for traction in snow. This means shorter stopping distances, better handling and better control in winter weather. Winter tires are not d
esigned for temperatures above 40 degrees Fahrenheit. The dow ...[more]
We often see customers who are a little overwhelmed by the tire buying process. There are so many types of tires for different vehicles and different driving styles, all at different price points. Here are a few things every driver needs to know about tires:
· A tire is constructed from the inside out, starting at the inner liner. There are 20 to 25 different components in every tire; fabric belts are wrapped around the inner liner, with steel belts, more fabric belts and other materials layered between the tread surface and the inner liner. These layers provide strength, noise suppression and ride quality.
· Newer low-profile tires are popular with many drivers, if only for aesthetic/style reasons. It’s important to know low-profi ...[more]
