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 ...[more]

No Spare Tire?

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.

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 vu ...[more]

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

June 16th, 2016

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 m ...[more]
