You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information. There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on. Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles. If there's no letter, it means it's a metric tire. If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall. The number that follows in our example, 70, means the height of the tire is 70% of its width. The letter after that in our example, R, describes the type of tire (on this vehicle, radial). Following that is the diameter in inches, in our SUV example, 17 inches. How much load the tires' sidewalls are designed to take ... read more

There are some boots that don't come in a shoe box and aren't worn on your feet. They are called axle or CV boots, and they can be important parts for many vehicles. That CV stands for constant velocity. CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They're also used in some rear-wheel drive vehicles with independent suspensions. They have two CV joints, one inner and one outer, placed between the axle and the drive wheels. That way the vehicle's engine power can drive the wheels, no matter what angle they are. They also adjust for the different speeds wheels turn as they go around corners. Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected. They also have grease in them to keep the bearings moving smoothly. That's the job of the rubber boots that are supposed to keep that debris out. These CV or axle boots are made of rubber or plastic and usu ... read more

Engines required a lot more maintenance in earlier times. You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically. There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you. That service was called a "tune up" back then, and you can see why. But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be. In fact, in some vehicle service facilities, that term is also a thing of the past. A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals. Your vehicle's manufacturer has made recommendations on how often that ... read more

You spend a lot of money on a vehicle, probably the most money you'll spend on anything except a house. But the spending doesn't stop after you've bought it. It goes into things like insurance, repairs and fuel. One good piece of news is that you can cut down the amount you spend on fuel if you follow a few tips. Keep your speed under 50 mph/80 kph. Anything over that and your fuel economy will go down quickly the faster you go. Sure, you can legally drive faster than that, but practice this one tip and it can save you from 7%-14% on fuel. Use cruise control. The steady speed increases fuel economy by avoiding unnecessary braking and accelerating. If your vehicle is carrying unnecessary weight, unload it. If you can save 100 pounds/45 kilograms, it can save you 1% of your fuel. Don't idle. Let's say you're sitting in a parking lot with your engine running for 10 seconds. Any more and you're wasting fuel. Turn ... read more

Bet you didn't know: Some of the earliest rearview mirrors were marketed as "Cop Spotters" so drivers would know when police were following them. Who wants a ticket, anyway? According to eBay Motors, Elmer Berger first patented a rearview mirror that was mounted on the front fenders, on the spare tire secured to the side of the car of at the top of the driver's door frame. About 80 percent of your vehicle is recyclable. So says The Balance. That means four-fifths of most vehicles can be recycled. Much of that recycling is done by automotive aftermarket recyclers. Between the U.S and Canada, they reclaim enough steel to produce 13 million new vehicles. The man who invented the first modern cruise control couldn't even drive a car because he was blind! His name, says Smithsonian.com, was Ralph Teetor. Blinded at a young age by a knife accident, Teetor was inspired to create a speed control by a couple of things. One, the U.S. imposed a mandatory 35 mph/55 kp ... read more

They say your vehicle has one, but you've never seen it. And you might not even know it if you stumbled on it accidentally. We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire. So you say you'd never try to change a flat anyway, so you don't care where it is. But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do. Well, here's the ironic part. Many of today's vehicles don't even have jacks and spares! Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor. If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it. Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prev ... read more

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you. No, really, it is. So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on. One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels. Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. Think of it. Hydraulic power steering has many components that need to work in tandem. The power steering fluid may be too old and contaminated. Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front. Yo ... read more

Sometimes the movie is better than the book, sometimes it's the other way around. But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book. They'll only read it when they absolutely have to, for things like finding out how to change the clock. Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover. We know that. But just think of what you can get out of it. Consider this. Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it. They know more about your vehicle than anyone, period. They know how long a part is likely to last and what ... read more

When you head to the doctor, you probably have it in your mind what you're going to say about why you don't feel good. That way your doctor can use that information to diagnose your problem. You might want to think of that same approach when you take your vehicle in for a repair. Experts say what will help the service advisor most is for you to bring in some well-organized descriptions about your vehicle's issues. You might even want to write them down so you don't forget. Is there an unusual smell? What does it smell like? Does the problem happen first thing after starting out? If there's an odd sound you hear, is it dependent on speed? Does it change when you turn a corner? Keep your expectations realistic. Some conditions may take a long time to diagnose and repair. If you go thinking you'll be in and out in no time, you might be disappointed when you're told there are other customers ahead of you and you may have to come b ... read more

As the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer. Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts. How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils. Here's the difference. A single viscosity oil will flow better when it's hot but not as well when it's cold. A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures. In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm. That's a pretty cool trick and it's why mu ... read more
