Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.
A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]
If you’re old enough, you probably remember the cars from the late 70s and early 80s that weren’t good for much more than 120,000 miles before they started to develop real problems and were junkyard bound. Today, thanks to improvements in design, metallurgy, manufacturing techniques and machining, those days are over and it’s not at all unusual to see vehicles with well over 200,000 miles on the odometer and still running strong.
Here’s a quick rundown of some vehicles to consider which have a track record of being good for 250k miles or more:
- Toyota Corolla: Probably not a surprise to fans of Toyotas, the simple, no-frills Corolla hasn’t changed much since the early 00s…but Toyota’s approach to the tried-and-true Corolla ...[more]
Tires all look sort of the same…round and black…and people tend to think tires don’t change much over the years. That’s really not true, though – engineers and designers are constantly working on advances in tire designs for more miles, better fuel economy and better performance.
Here’s a rundown of current trends in tire technology you may not have been aware of:
- Tall, skinny tires are coming back. If you’ve ever ridden a beach cruiser bike vs. a racing bike, you know that skinny tires have lower rolling resistance. Carmakers are going in that direction, too – the BMW i3 electric/plug-in hybrid uses Bridgestone Ecopia tires, with higher inflation pressure and a taller, skinnier profile. Tall, skinny tires also redu ...[more]
When it comes to your car, oil isn't the only thing there's a finite supply of. Rubber has its limits too, and it's estimated by 2020, the supply of natural rubber in the world may be outstripped by demand. And of course, tires require a great deal of oil to produce as well. Tire manufacturers are constantly looking for ways to innovate and conserve resources in tire production. Here are some recent advances:
- Dandelions: Yes, those humble yellow flowers you try to eliminate from your yard. Dandelions actually contain a minute amount of latex in their milky oil, and research shows they can actually produce about as much latex, pound-for-pound, as rubber plants. German scientists have cultivated 1-foot-tall dandelions for just this purpose. This isn't a new development, either -- in WWII, Amer ...[more]
At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:
- Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- the lower the number, the thinner the oil. Many are designed to work a ...[more]
Years ago, your dad might have told you that “pumping” the brake pedal was a good idea on wet or slippery pavement, so you could maintain control of the
vehicle without locking up any of the wheels and sending the car into a skid. Well, that’s some pretty outdated advice today.
Every vehicle now features antilock brakes (ABS), which greatly in vehicle control during an emergency stop. ABS brakes use a sensor at each wheel to monitor the wheel’s rotational speed. That information is then sent to a processor; if any wheel is in danger of going into a skid, the processor meters braking (through a system of pumps and valves) to reduce braking effort to that wheel. This is a cycle that happens hundreds of times per second, with the ABS system essentia ...[more]
The mechanics of how disc brakes function haven’t changed much for a long, long time. Sometimes, at Tire Central and Service, we run across customers who
have some misconceptions about how they work, or about “innovations” in brake design that aren’t really worth it. Here, we’d like to clear up some of those myths:
Q: I see sports sedans and coupes from time to time with holes drilled through the rotors. Is there an advantage to this?
A: Really…no. The idea of drilled rotors is to (in concept, at least) provide better ventilation and disperse heat. In practice, though, those evenly-spaced ...[more]
At Tire Central & Service in Indianapolis, IN, we’re proud to carry the Goodyear tire product line, and one of our most popular, best-selling tires is the Goodyear Eagle RS-A. The Goodyear Eagle line has been around for a long, long time – one model of the Eagle series is standard equipment on many police vehicles – and the RS-A is a great choice for drivers of sedans who are looking for an excellent high-performance all-season tire at a surprisingly reasonable price. Here are a few of the strong points of the Goodyear Eagle RS-A:
· The Goodyear Eagle RS-A is designed with an asymmetric tread pattern for a quiet ride and excellent traction, cornering ability and straight-line, on-center road manners.
· &nbs ...[more]
- All four tires should be the same brand and close to the same age. At the very least, they should all be the same tread pattern, size and type of tires. We know that on older vehicles, this may not be a priority, but mismatched tires ...[more]
