Five Things You Didn’t Know About Tires

March 16th, 2017

Tires1. For performance and handling, the trend has long been toward fatter tires with a bigger footprint. That’s starting to change, though. Skinnier tires mean lower rolling resistance and better fuel economy, as well as a smaller aerodynamic profile. While fatter tires do handle better, tire engineers are making up the difference by designing skinny tires with a stickier tread formulation for traction and cornering ability.

2. Static electricity used to be a real concern for vehicles; if you’re old enough, you may remember seeing station wagons with a “ground strap” dragging along the pavement. It’s become a concern again, with newer tread compounds cutting back on the amount of carbon black in newer tires. The solution? Many tires are now designed with an “antenna strip” ...[more]

Can I Buy Just Two Tires?

February 9th, 2017

We know that a lot of drivers are working pretty hard to make a dollar go farther and that the outlay for a full set of four tires – even inexpensive tires – can be considerable. That’s why we run across drivers pretty often who ask if it’s okay to just replace a pair of tires, then buy the other pair when they can afford them.

The answer is…yes, but…New Tires

You’ll really need to pay attention to the size of the set of tires that you’ve already got and go with that exact same size of tires for your new pair. Having mismatched sizes of tires on your vehicle can result in squirrelly and unpredictable handling and ride quality. If your existing tires are all-season, go with all-season tires. If they’re winter tires, go with winter tires. Ideal ...[more]

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 Explanation of Tire Information

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]

A Brief History of the Tire

September 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 ab ...[more]

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

September 28th, 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

September 28th, 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 dev ...[more]

4 Things About Tires You May Not Have Known

September 28th, 2016

Tires all look sort of the same…round and black…and people tend to think tires don’t change much over the years. That’s really not true, though – engineers and designers are constantly working on advances in tire designs for more miles, better fuel economy and better performance.

Here’s a rundown of current trends in tire technology you may not have been aware of:

  • Tall, skinny tires are coming back. If you’ve ever ridden a beach cruiser bike vs. a racing bike, you know that skinny tires have lower rolling resistance. Carmakers are going in that direction, too – the BMW i3 electric/plug-in hybrid uses Bridgestone Ecopia tires, with higher inflation pressure and a taller, skinnier profile. Tall, skinny tires also reduce the car ...[more]
