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]

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.

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]

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]

Are All-Season Tires Really All-Season?

September 11th, 2015
We frequently get questions about all-season tires when consumers are trying to make the right purchasing decision for  a set of new tires. As the title of the blog asks…”are all-season tires really all-season?”
 
The answer is: it that depends on what part of the country you’re living in.
 
All-season tires are a compromise from the very start. They’re designed for a forgiving ride, low noise, decent handling and good road manners. Maybe not as much as what a good set of grand touring tires can deliver, but pretty respectable…and also with an aggressive tread pattern which 
channels water away from the tire’ ...[more]

Do Your Homework on Tire Safety

August 13th, 2015
We see it all the time…people tend to not think about their tires until something goes wrong. Sometimes, this can mean sitting on the side of the road waiting for help, and other times it can mean more serious consequences. Here are a few things to remember for tire safety as the summer winds down and back-to-school season starts.

Check your tire pressure regularly. This one is really important. Your car’s tires will lose air through the valve over time, and an underinflated tire will hurt fuel economy due to added rolling resistance. Low tires also affect handling and will generate enough heat that they can shorten the tire’s lifespan. Get a quality tire gauge (the dial type, not the pencil type) a ...[more]
