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]

No Spare Tire?

September 29th, 2016
Believe it or not, many new vehicles come without a spare tire. Manufacturers have a few different reasons for that, including weight savings, space efficiency, Spare Tireand cost. When you're stuck by the side of the road, though, none of that really matters much, does it? 
 
Instead, these vehicles come equipped with an inflation kit and/or a can of sealant. 
 
Sealant is a gooey substance in an aerosol can that's designed to coat the inside of the tire due to centrifugal force once you get rolling again, hopefully sealing the puncture. These products, such as Fix-A-Flat, have been on the market for decades and tend to work pretty well on a minor puncture. They're not a permanent fix, however. Your speed should be limited after using ...[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]

4 Things About Tires You May Not Have Known

April 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 redu ...[more]

Self-Inflating Tires…Soon To Be A Reality?

March 31st, 2016

Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.

A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]

Mixing Tires – Bad Idea

February 25th, 2016

In a perfect world, all four tires would wear out at the same time. In the same perfect world, everyone would be able to afford a whole set of tires all at once. Unfortunately, things often just do not work out that way. 

Sometimes you may just have to replace tires as you can afford them, one or two at a time, but there are some important things to bear in mind if you have to do that. 

If you can only afford to replace one or two tires, it’s essential that you go with tires that are identical (or at least as close as possible) to the car’s remaining tires. That means that internal construction, size, tread pattern and design should be close to the same. Don’t mix winter tires with all-season tires, don’t mix run-flat tires with ...[more]

Get The Most Out Of That Set Of Tires

January 28th, 2016
Your tires are a pretty big investment. Even with the cheapest set of tires, you’re going to be spending upwards of $400 on the tires, mounting, balancing, disposal fees and taxes. Since you laid down that kind of money, doesn’t it just make sense to make sure you get the most miles possible out of them? 
Here’s some advice on long tire life:
 
Regularly check your tire pressure. This one is really, really important. Underinflated tires will wear 
unevenly and reduce your fuel economy due to increased rolling resistance. That increased rolling resistance also means more heat, which will break down the tires’ internal structure and sh ...[more]

Winter Tires – Yea or Nay?

December 31st, 2015
In a lot of parts of the country, the winters are tough enough that all-season tires just won’t get the job done. All-season tires are a compromise; they offer good year-round traction with a quiet ride, good handling and road manners. They tend to perform well in wet weather and light wintry conditions, but when the snow is more than a couple of inches deep, all-season tires are out of their league. That’s when it’s time to consider winter tires. 
 
Today’s winter tires are a long way from the heavy, noisy, clumsy “snow tires” or “mud grips” that your dad might have had on his station wagon 40 years ago. Modern winter tires are designed for noise, handling, steering response and road manners that rival grand tourin ...[more]
