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, and 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 aga...

You know that winter and bad weather are coming. Is your car ready? Here’s a quick checklist of things to get up to speed on: Motor oil: Motor oil has a tendency to thicken in cold weather, making it harder to circulate to upper engine parts at startup. If you haven’t ever used synthetic oil before, this might be a good time to start. The flow properties of synthetic oil are a lot more consistent, meaning it doesn’t thicken in sub-freezing temperatures or thin out when it’s hot outside. Wip...

Ever think about all the different vehicles that use rubber tires? Tractors, industrial equipment, everything else that rolls on rubber? Each specialized type of tire requires a specialized design for its specific purpose. Aircraft tires, for instance, have to be very robust and handle a great deal of weight and stress, but for only a short period of time. Aircraft tires are often filled with an inert gas such as nitrogen, for more stable inflation levels, and are designed with specialized fusi...

Every year, about 290 million tires are discarded; of those, about 233 million are recycled in one way or another. Shredded tires can be used for playground surfaces, welcome mats, hot-melt asphalt, bark mulch and even made into building material for “green” construction. But what can you do with your old tires? Here are some ideas: --Fill a tractor tire with sand to make a great sandbox for kids --Hang a tire from a rope as a tire swing --Stack a couple of tires on top of each other, bolt th...

You rely on your car every day, and you have a lot of money tied up in it. It’s probably one of the more valuable things you own…so make sure you get the most out of that investment: Oil changes: Changing your motor oil at regular intervals will ensure long engine life by cutting wear and friction and helping to prevent the buildup of sludge and carbon on internal engine assemblies. Cooling system: Older cast-iron engines could overheat with no serious consequences, but not so with today’s a...

Ever wonder what the designations stamped on your tire sidewall actually mean? We’d like to break it down for you. Let’s take for instance, “P195/60R15 87S”. This is a full service description of a tire. In this case, “87S” denotes a tire’s load capacity and speed rating. The higher the number, the greater the load capacity – an 87 load capacity means that tire can support 1,201 pounds. Speed ratings range from L (75 mph) through V (149 mph), and an S speed rating means the tire is good...

Yes, there are plenty of traffic laws in certain areas that don’t make much sense. Here, though, we present a collection of traffic laws from other parts of the world that are just bizarre: --In Thailand, the law states that no driver, male or female, shall ever drive without a shirt. --In South Africa, “the driver of a vehicle on a public road shall stop such vehicle at the request or on the signal of a person leading or driving any bovine animal, horse, ass, mule, sheep, goat, pig, or ostri...

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? 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...

Yeah, yeah…your vehicle’s fairly new and you take care of it, and you’ve even got a membership in AAA. That doesn’t mean that your chances of ending up in a tight spot are zero. It’s just common sense to be prepared with a trouble bag in your car. Here’s a pretty good rundown of things you should keep in a car emergency kit: Fully charged cell phone: You may want to consider a cheap prepaid “burner phone” with a long battery life and keep it strictly in the car. If nothing else, at leas...

We know that a lot of drivers are working pretty hard to make a dollar go farther and that the outlay for a full set of four tires – even inexpensive tires – can be considerable. That’s why we run across drivers pretty often who ask if it’s okay to just replace a pair of tires, then buy the other pair when they can afford them. The answer is…yes, but… You’ll really need to pay attention to the size of the set of tires that you’ve already got and go with that exact same size of tires for...
