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]Read More
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]Read More
Thinking about getting a set of mud terrain tires for your full-size truck, 4x4 SUV or Jeep? Let’s compare the BF Goodrich Mud Terrain and Maxxis Bighorn.
Both tires use a rubber formulation that’s optimized for off-road use, meaning cut and puncture resistance and enough flexibility to conform around off-road obstacles like rocks and stumps when aired-down. The BF Goodrich, however, features the company’s Krawler TEK construction in the sidewall, an feature that makes them up to 33% stronger than previous generations of the Mud Terrain T/A KM. The Goodrich also features a single strand of bead wire wound over and over for an extra-strong, tight bead seal.
In an effort to wring more fuel efficiency out of the F150, the 2015 model from Ford will use aluminum body panels on top of a high-strength (yet lighter) steel frame. The move has shaved 700 lbs from the truck’s curb weight, but it has had its detractors along the way, as people still tend to think of aluminum as beer-can material. Ford did their homework, however.
It turns out that Ford has been testing all-aluminum F-series trucks since 2009, running them in torture tests like the Baja 1,000 and not finding any body cracks or defects at the end. The company has also taken 2014 models, fitted them with aluminum, sent them to fleet buyers and tracked the results; even with extreme usage (like dropping an oilfield drill bit into the bed), the aluminum body panels held up as well as or better than steel.
While aluminum is more e ...[more]Read More
As manufacturers squeeze all the fuel efficiency they can out of their designs, aerodynamics have been a huge concern –as well as looking sleek and advanced, an aerodynamic car cuts wind resistance for enhanced fuel efficiency. Modern designs are a pretty far cry from the boxy sedans of the 70s and 80s, but aerodynamics is hardly a new concern.
All the way back in 1923, Romanian engineer Aurel Persu ruminated on the ideal aerodynamic design; Persu decided that the ideal aerodynamic shape found in nature was a raindrop as it falls to the ground, with a super-low drag coefficient of 0.04. With that as a target, he began to draw up an aerodynamic sedan, with tall wheels mounted flush with the body inside fender wells, a steeply-raked front end, rear wheels spaced much more closely than the front, rounded contours and a rear end that tapered sharply. The Persu ...[more]Read More
Something about the mid-size B-body Dodge/Plymouth cars has always held an appeal; their no-frills appearance called to mind a muscle car version of a highway patrol car. In ’68, Plymouth already had the GTX , based on the Satellite two-door, but they felt the need for a stripped-down counterpart to the more upscale GTX. Their goal: a car that could run a 14-second quarter mile and sell for under $3000.
Chrysler paid $50,000 to Warner Brothers for the name and likeness of Wile E. Coyote’s nemesis the Road Runner (as well as $10,000 to engineer a “beep beep” horn), and the Road Runner was born. The no-frills Road Runner had a plain-jane cloth-and-vinyl bench seat and rubber floor mats; its base engine was the 335-hp 383 V8. For an extra $714, you could get the Road Runner with the 425-hp ...[more]Read More
Before we start talking about which tires you need, you should determine whether it’s time to go ahead and get tires…
The minimum depth where tire tread is still effective is 2/32”. Anything lower than that and your tires will no longer resist hydroplaning in wet weather, dry traction is reduced and traction in snow is practically nonexistent. Tires now include “wear bars” at the base of the tread, running at a right angle to the tread; when the wear bars show through, the tires are at the end of their service life. The old-timer’s gauge is the “penny test,” where you put a penny, Lincoln’s head down, into the tread. If the top of the tread no longer touches Lincoln’s head, then it’s time (some now recommend the same test with a nickel or quarter).
Of course, when yo ...[more]Read More
The word “ubiquitous” might have been coined specifically for the Honda Civic. Civics are so common, such an everyday sight that you don’t even notice them anymore…until you actually pay attention and realize that there are a LOT of Honda Civics on the road.
On July 23, 2007, the six millionth Civic rolled off of Honda’s production lines; the Civic was introduced in 1972 and has been through numerous generations and nine separate design iterations along the way. The tiny two-door first-generation Civic couldn’t have come along at a better time; in ’72, the American auto industry was being shaken up by the first oil crunch as the Middle East turned off the spigot. Big, wasteful cars were suddenly on the outs, American companies were scrambling to introduce (very mediocre) small cars, and in no time the ...[more]Read More
Tires are something that most people just do not give a lot of thought to until something goes wrong and it’s time to replace them. The good news is, they don’t really need a lot of maintenance (certainly not as much as your car’s mechanical systems do), and it’s pretty easy to take care of them and get a long service life from them. Ther e are a few things, though, that you do need to keep in mind with your new tires.
- Watch your driving habits. Obviously, if you regularly mash the gas pedal hard enough to break traction and burn rubber, that will take a lot of life off your tires. Besides that, though, be careful about your braking and cornering habits, and go easy over potholes and railroad tracks; they will all take a toll on your tires.
- Check your ...[more]
Performance cars need performance tires. But what’s the difference between performance tires and ordinary touring tires?
Performance tires are usually made with a softer tread compound for “stickiness” and improved grip, reaction and handling on dry pavement – the compromise is in shorter tread life. Many true performance tires also don’t do well in colder weather, and many drivers switch over to all-season or winter tires in colder months.
Tires with H or V speed ratings are typically considered “performance touring” tires, and many are designed for all-season wear. Tires with the W, Y or Z rating (and an aspect ratio of less than 55) are ultra-high-performance tires, designed for high-speed handling.
We rounded up a few of our best- ...[more]Read More
