At GM Electronics we are one of the top premier outlets for tires in Concord, Ca. But what sets GM Electronics apart from everyone else is that we'll meet or beat any price on tires. Typically, tires are one of the last things we think about while we're driving our cars everyday. However, tires have a huge impact on any vehicle because they are the only part of the car that come in contact with the road. Tires directly impact your cars gas mileage, safety, comfort, and overall performance.
Tires are a big deal, but most of us aren't educated as much about tires as we'd like to be. Not knowing about your tires could result in many inconveniences and even an accident. Here at GM Electronics we promote safety and will give you the basics about tires to help your avoid any harmful situations. We'll save you time, money, stress, and hopefully an accident.


Your tires tread should never fall below 1.6 millimeters (1/16 of an inch) in depth. If you regularly drive on wet, slick roads or surfaces, it'd be safer to have twice that amount of tread. There's an old method that will provide you with a rough estimate of how much tread depth you have left and it requires a penny.

Take an Abraham Lincoln-head penny, and insert his head down into the tread of your tire (see the picture). If Lincoln's entire head remains visible, you cars tire doesn't have enough tread. If your tire doesn't have enough tread take it to GM Electronics and we'll find the best and most economical tires for your vehicle.


Most tires today have tread wear indicator bars built into the tires themselves. These bars, will be either invisible or barely visible when the tires are new and first purchased. They gradually begin to appear as the tread wears down. The indicators look like flat rubber bars running perpendicular to the direction of the tread itself. If more than one or two of these are visible on a tire, the tires tread is getting low. The signs should be noticeably obvious in the wet tracks that your tires leave after you drive through a puddle. Use the penny to test the depth. But if the bars are starting to appear on any or all of your tires then please stop by GM Electronics and we'll find the right tires for you.


Not all problems with tires are going to be in the tread. They can also appear in the sidewall. Fortunately, it's easy to visually see sidewall problems. Look for tracks or cuts in the sidewall -- these grooves are distinct enough to be seen with your eyes. This could be a sign that your tire is developing a leak (or worse, that it's nearly ready to blow out). This is definitely something you want to avoid. So if the cracks in the sidewall are starting to look serious, get that car to GM Electronics tire repair shop as soon as possible and we'll get them replaced. It is better to be safe than sorry.


Sometimes the outer surface of the tire begins to weaken. The issue can be a bulge or blister that extends outward from the rest of the surface. This is similar to an aneurysm in one of your blood vessels and you know that if your doctor tells you that you have an aneurysm, you'd better get to the hospital as quickly as you can before you blow out an artery. It's the same principle with your tire. This weak spot can cause a sudden blow out, and if you don't put the car in the hospital (our service center) before this happens, it may end up putting you in the hospital when the tire blows out on the freeway. So keep your eye on those tire bulges and blisters.


A certain amount of vibration is inevitable when driving, especially on poorly paved roads, but if you've been driving for a while, you probably know how much vibration feels normal and how much means that something's going wrong. There can be any of a number of causes for the vibration -- maybe your tires are misaligned or unbalanced, or your shock absorbers are starting to go. But it could also indicate that there's some sort of internal problem in the tire itself. Even if the tire isn't the root cause of the vibration, the vibration could damage the tire and pretty soon you'll have a problem. So if your car has a bad case of the shimmy-shimmy shakes, especially if you notice this when you aren't driving on bad roads, take it to GM Electronics right away to have it checked out. Too much vibration is almost always a sign that something is wrong.
