Flat Spots? Let’s Clear Up Some Myths About That…

January 12th, 2017

So your vehicle’s been sitting for a while…you get in it, start the engine and pull out of the driveway when you notice a hard, rough (but very regular) vibration that only gets worse with speed. It doesn’t feel like it’s coming from the driveline or suspension – so what is it?

Flat spots on tires

It could be that the tires have developed flat spots.

With the weight of the vehicle pressing down on the tires for long periods, a section of the rubber and belts can become softer (or harder) than the rest of the tire. This can be exacerbated by cold weather, or just by parking on a cold concrete floor.

Low-profile tires with short sidewalls can be more prone to flat-spotting, as can tires with an H or higher speed rating. In most cases, you can j ...[more]

A Brief History of the Tire

December 15th, 2016

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:Tire

--“P” denotes Passenger Tire

--195 is the tire’s width from si ...[more]

What To Do With Those Old Tires

November 10th, 2016

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 kidsTire swing

--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]

So…Many…Kinds…of Tires

October 27th, 2016

Different Types of TiresEver 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]

Which Type of Tire Tread Do You Need?

August 25th, 2016
There are so many tire designs on the road -- all-season, high performance, touring, light truck -- and even within a specific tire design, there may be several Different types of tire treadchoices of tread patterns. What differentiates them, and what are the pros and cons of each tread design? 
 
-- Directional tread has a pattern of grooves and chevron shapes, all pointed in one direction. This design makes it easy to direct water away from the tire's contact patch and prevent hydroplaning in wet weather, and also offers low noise and great road manners. The directional design means tires can only be rotated front-to-rear and not side-to-side or diagonally. 
 
-- Symmetrical tread patterns feature grooves or herringbone designs that ar ...[more]

A Brief History of the Tire

July 28th, 2016
The tire is such a commonplace item -- it's on every car, every truck, every bicycle, every aircraft. It's easy to not give the tire a second thought, but like every other technology, the tire has an interesting history of advances and failures. 
 
In the 19th century, carriages and wagons used steel strips for "tires" on their wheels, with the punishing sort of ride that you'd expect. In later years, they were shod with strips of natural rubber, which was an improvement but was still problematic. Solid rubber still rode pretty rough, and the natural, uncured rubber would get gummy in hot weather and shrink and harden in cold temperatures. Charles Goodyear was able to help with the invention of vul ...[more]

So You Get A Flat Tire...What Now?

June 16th, 2016

Flat TireNobody 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]

The Latest in Green Tech Innovations for Tires

May 12th, 2016

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]

Don’t Let Tire Problems Put the Brakes on Your Valentine’s Date

May 3rd, 2016
Don’t let tire problems get in the way this Valentine’s day. How is your tire pressure? Do my tires need to be rotated? Is it time for an alignment? Do I need new tires? While these questions can seem daunting, with the help of tire professionals and various routine self-checks, any driver can maintain proper tire care and not miss that big date this Valentine’s Day. From tire rotations to air pressure, learning what signals might indicate tire replacement or repair is important for every vehicle owner. 
 
Let’s begin with tire air pressure. Perhaps one of the most obvious tire maintenance steps most drivers neglect until it’s too late is checking your tire’s air pressure. Even careful drivers with perfect tire upkeep lose around 1 psi (pound per square inch) per month, culmi ...[more]

What Makes All-Season Tires So Great?

May 3rd, 2016

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]
