Alloys or steel wheels: What's best for you? Both types have advantages and disadvantages for different types of driving; but in general if you want beauty and performance you want alloy, and if you want tough, inexpensive, ugly workhorses, you want steels.

Irregular tire wear is a frustrating little gremlin that can steal your tires' performance and tread life if you let it. The problem is that irregular wear comes in so many different flavors. The causes of strange tire wear can range from air pressure to improper balance, from misalignment to bent wheels.
Wheel balancing, also known as tire balancing, is the process of equalizing the weight of the combined tire and wheel assembly so that it spins smoothly at high speed.
Does your car shake at speed? How to tell if your car's vibration is coming from bent wheels or tires.
We all know that wheels come in many different diameters – anywhere from the tiny 14” steels to 24” chrome monsters and beyond. But wheels also come in different widths, and the width of the wheel not only affects how the wheel sits on the car but also how the tire fits on the wheel. Here's a look at how wheel widths affect you.

Tire Size Calculators are one of those things you don't need until you really need one, because nobody wants to do tire sizing math in their head. Here is a list of some of the best ones.

When it comes to finding the proper fitment for putting aftermarket or other new wheels on your car, the bolt pattern is possibly the most important consideration.
There is a great deal of debate going on nowadays about the proper way to repair tires, whether plugs are sufficient for small repairs or whether plugs are dangerous and patches are the only proper way. In fact, this is a debate that has gone on for literally decades. Plugs are an easy and cheap way of repairing small nail holes, while patches are a more involved, more complex and probably safer way of doing much the same thing.
If what you want is superior grip for a high-performance car in both dry and wet conditions, and you plan to either switch out to pure winter tires or not drive the car in the snow, one of these “performance” all-seasons may be just your cup of Texas tea. In general, these tires are excellent for driving from spring through fall, or year-round in climates where you just don't get all that much snow.
Confused about what that letter means right after your tire size? Ever had a tire shop ask what your speed rating was and didn't know what they meant? Don't know whether you need the more expensive V- or ZR-rated tires that the car came with? Fear not, mighty consumer, for I will edify you.
The Firestone Destination LE2 does exactly what it's supposed to do. And no more.
The idea of all-season tires is always a compelling one. Having tires that can be kept on your car year-round, that work well in both the winter and summer is generally a whole lot easier and cheaper than switching between winter and summer tires. The thing is, the requirements for tires designed for summer performance and tires designed to function in snow are extremely different even down to the rubber compounds, which makes it very difficult to make a tire that excels in all regimes. This means that designing all-season tires has always involved some very important tradeoffs.
Tire performance categories can be enormously confusing. This can be very important information, because you're going to want a tire that fits your car and driving style. If you don't know the differences, it can be very easy to upsell you into a higher performance, more expensive tire when what you really wanted was something with a smooth ride that will get you to the store and back, or vice versa.
Runflat tires are being used more and more by carmakers. Here are some reasons why not to use them.

The Bridgestone RE97AS is designed to have a smoother and quieter ride than the RE970AS, but has somewhat less track-style performance. At the same time it has more performance and a less smooth ride than, say, the Ecopia line, making it pretty much a “Goldilocks” tire in most respects.

What's the deal with reconditioned wheels? There's a right way, a wrong way and a third way to go about it.
Deep concave wheels are designed with spokes that curve, more or less gracefully, inwards toward the hub center of the wheel, such that if you put the wheel face up and flat on the ground, the cosmetic face of the wheel would form a bowl shape. When on the car, that bowl shape curves inward towards the car's suspension, creating a very interesting and sometimes even jarringly fresh look.

When Bridgestone looks at the state of the SUV/Light Truck market, they see that it is transitioning away from big heavy SUV's and towards much lighter, sportier “crossover” vehicles. As they note, this is what “The Boss” wants from the car companies, and what “The Boss” wants from these CUV's is not just ample cargo space and better fuel mileage, but the kind of responsive acceleration, braking and handling that crossover-type vehicles provide. That's where the Dueler H/P Sport comes in.

As a reviewer, I try to make clear when I have a bias, whether positive or negative. I do have something of a negative bias regarding Pirelli. Mostly this comes from years of doing tire repairs and seeing lots of “bubbles” in apparently weak Pirelli sidewalls. I do freely admit that this is partially because they tend to aim for very high performance, and partially because they tend to make a lot of very low-profile tires. With the P Zero Nero All Season, however, the sidewalls are clearly not the issue. The issue is the lack of real wet grip and the ease with which the tire breaks away at the limit.
It can happen anytime; you're stuck on the side of the road with a flat tire. You can wait for a tow truck, or you can change the tire out for your spare yourself and be on your way. Here's how to do it safely and easily yourself.
