Tire Sizes Explained


Tire Sizes Explained!

Finding your tire size may be hard at first, but once you know where it is listed and what each number means, it becomes very easy, even easier each time you need it in the future.  Tire sizes are made of of three numbers, first is the tire “Width”, second the tire “Ratio”, and third is the “Rim” size/diameter.  These numbers are located on most every car's inner door jam, as well as on the older/current tires outside wall.  Using the size on the outer sidewall is very important if your car does have an aftermarket or replacement wheel that was not stock from the factory.

What’s the Proper Air Pressure For My Car


Experts and analysts seem to be in agreement on this: the days of cheap oil are finished. As countries compete with each other for oil on a global market, the price of refined fuel and gasoline in the United States may fluctuate somewhat, but it’s likely to stay above $3/gallon for the foreseeable future. That means that every driver needs to be aware of what they need to do to optimize their gas mileage…and that includes tires.

Proper Inflation

You probably already know that proper inflation is vital to fuel economy, and that underinflated tires will not only drop your gas mileage, but will negatively affect handling and drivability. Underinflated tires are also unsafe, building heat that can compromise a tire’s service life and possibly cause tire failur ...[more]

The Importance of Rotating Your Tires


Rotating tires is one of the most important (and easiest) things you can do to prolong their service life. But why? Why is it so important?

It’s simple. Front and rear tires wear differently. Parallel parking, cornering, acceleration, three-point turns all put different stresses on the front and rear tires. Not rotating them means that they are going to show different wear patterns, which will affect their tread life and your car’s ride and handling.

Regular rotations mean that your tires will wear more evenly, and will improve your car’s drivability. Chances are you’ll notice a difference in ride and handling with every rotation. So how often should you rotate?

Every other oil change seems like a pretty good rule of thumb (in other words, every 7-10,000 miles). Doing rotations yourself in your ...[more]

What if I Have Mismatched Tires?


As a general rule, your tires should all have the same tread pattern, construction and size, meaning they should all be the same make, model and age. If they aren’t, you’ll compromise on your car’s control, traction, stability and ride. Mismatched tires could mean tires from different manufacturers, winter tires with all-season tires, run-flat tires with conventional tires or tires with different tread patterns.

Until you can invest in an entire set of tires of the same make and model, and if you’ve only got one mismatched tire in the set, you should put it on the rear. If the tire that had a problem was on the front, take one of your rears and put it on the front to replace it, then put the mismatch tire back on the rear axle. This will probably mean the least impact on handling ...[more]

How Tires Can Vastly Improve Your Fuel Economy


When you think of enhanced fuel economy, you probably think of the usual things…aerodynamics, engine size, rear end gear ratio, vehicle weight, driving style and speed, and your engine’s state of tune (clean air filter, good spark plugs, etc). Did you know, though, that your tires can have a huge bearing on gas mileage as well? 

  • Tire Size – The bigger, wider and heavier a tire is, the more rolling resistance it presents. Don’t believe me? Go for a ride on a skinny-tire racing bike, then go for a ride on a fat balloon-tire beach cruiser and see the difference. You shouldn’t go for a narrower tire than original equipment, as engineers tune suspensions and steering for a given tire size, but also remember that wider tires can cut into your fuel economy (even if th ...[more]

OE Tires vs. Replacement Tires


Soooo…it’s time to replace the tires on your late-model car. Maybe you weren’t that crazy about the original equipment (OE) tires, or you just want to try something different. Well, here are some things to consider.

The engineers and design teams that worked on your make and model of car selected a specific brand and model of tire for it. All of their formulations for ride comfort, handling, steering response, traction, noise and vibration isolation, roughness and  overall performance used that specific tire as a benchmark (of course, the bid process for tires entered into it as well). A luxury car might have been designed around a grand touring tire with a quiet ride, an eco-friendly hybrid might use a low-rolling-resistance tire, ...[more]

How to Read Tire Sizes


Find Tire Sizes

Get a look at your tire sidewall and you’ll see information molded into the rubber, in the form of raised letters and numbers. We’d like to explain to you what that information means, so let’s break it down:

  • Load Index – The load index is a reflection of the maximum weight that is safe for a tire to carry. The load index numbers range from 0 to 279; passenger car tires are usually in the 75-105 range. When it’s time to replace your tires you’ll want to pay close attention to those numbers.
  • Speed Rating – Speed rating designations are assigned by the U.S. government, and are an indicator of minimum standards for accelerating to and holding a certain specific speed. The higher the speed rating number on a tire, the better a v ...[more]

5 important things to consider when shopping for new tires


Although picking out new tires can be a daunting endeavor, there are two important pieces of information you can identify that will greatly ease the process. First, you must recognize exactly what it is that you need most from your tires. This means that before you even begin to establish a list of criterion that make up the perfect tire for you, you must be aware of exactly what kind of road issues and driving conditions your tires will be faced with. Be it varying road surfaces, a majority of city driving, high speed driving or other high performance requirements, identifying this need is a definite necessity. Second, you must find a reputable or trustworthy source to purchase your tires from. If you have had a bad experience at a particular shop, you are better off trying a new one than returning to the old one and giving them repeat business. If you suspect that a tire dealer may be placing his bottom line ahead of your best interests then you should feel free to shop around ...[more]
