What Do the Numbers on a Tire Mean?

What Do the Numbers on a Tire Mean?

Many car owners ask the question, “What do the numbers on my tires mean?” There is a lot of information printed on the side wall of every tire. This week, we’ll be examining an often overlooked set of tire number meanings. Your tire’s birth date or “tire birthday” is the approximate time that the tire was manufactured, and it's very important information to know when it comes to maintaining your vehicle. Read on to learn more about your tire’s numbers. Locating and Reading the Birth Date The tire birth date is not really a specific date, but rather the week and year the tire was manufactured. You can find it by locating a set of numbers that begins with “DOT." This string of letters and numbers will end with 3 or 4 numbers. For instance, your tire’s numbers might read DOT DA07 JN2S 4212. That last number, 4212, is the “birthdate”. The first half of the numbers, “42," indicates that the tire was made ... read more

Here's Why Tire Pressure Matters

Here's Why Tire Pressure Matters

Tires are one of the most important parts of your car when it comes to performance and safety. Thus, it’s crucial that your tires are always in working order and properly maintained. In particular, tire pressure is one of the most overlooked aspects of tire maintenance. Normal tires may lose up to 1 PSI per month under regular driving conditions. Therefore, you should check your tire pressure at least once a month to ensure that they’re inflated to the recommended PSI. For your information, let’s see why tire pressure matters so much for your car’s overall operation. Dangers of Driving with Under-Inflated Tires Driving on under-inflated tires can create a whole host of different problems for the tires and for overall performance. Lower tire pressure can cause the tire to bend and build up internal heat. Having the tires deflated by as little as 5 or 6 PSI below the recommended pressure (20% below) can result in problems such as: Reduced fuel economy Loss of s ... read more

How to Prevent Hydroplaning

How to Prevent Hydroplaning

Hydroplaning, or aquaplaning, occurs when a car’s tires start riding on a layer of standing water. In effect, the car loses all traction as the tires are spinning on the water rather than making direct contact with the ground. This causes a situation where the driver can lose control of the vehicle’s steering, acceleration, and braking. While hydroplaning can be a harrowing experience, there are many things you can do to prevent hydroplaning. Here are some tips for preventing and correcting hydroplaning. Recognize when you’re hydroplaning If your car starts to hydroplane, you can probably tell because of certain signs, including: Small turns of the steering wheel have no effect; micro-corrections don’t really do anything (since the car really can’t turn as there is no direct contact with the ground) The engine may get louder as RPM’s increase because the wheels are spinning faster. The steering wheel may begin to shake as the wheels are spinnin ... read more

How To Prepare Your Car For Winter in SoCal

How To Prepare Your Car For Winter in SoCal

San Diego may not suffer the extreme temperature drops that other cities do, but that doesn’t mean we don’t have winter! In colder climates, drivers need to think about how to prepare their cars for winter: antifreeze, engine heaters, ice scrapers, snow tires...the list goes on. Here in Southern California, we only really have one major concern: tire pressure and condition. Image: Flickr As the temperatures drop in the winter months, the air in your tires gains density. That increased density means lower air pressure in your tires, leaving them under inflated. What does that mean? Underinflated tires can cause improper tire wear, reducing the lifespan of your tires. They can also reduce your fuel economy, as a tire with low pressure has increased resistance. Most importantly, an underinfla ... read more

Tire Nitrogen Fill in San Diego CA

So, everyone in the San Diego area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around still haven't heard about the benefits of nitrogen in your tires, and how it can help your tires. Here's some great advice from AutoNetTV, brought to you by Convoy Auto Repair. Nitrogen has actually been around for a long time in the commercial sector, but it's just starting to catch on for private vehicles in the 92111 zip code area. Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference. The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump. The problem is that tires filled with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don't check your pressure for a month o ... read more

Convoy Auto Repair Tire Safety: Washington vs. Lincoln

Convoy Auto Repair Tire Safety: Washington vs. Lincoln

Welcome to the Convoy Auto Repair blog. Today, let's talk about the effect of tire tread depth on braking. When talking about stopping power, most of us drivers tend to focus on our brakes. But our tires are where the rubber meets the road. So having good brakes isn't enough. Safe drivers need to have tires with enough traction to translate braking power into stopping power.Let's focus on stopping in wet conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can't move the water, the tire will actually ride on top of a thin film of water. That's called hydroplaning. If it's really bad, drivers can actually spin out of control. At best, you won't stop as fast. So how does a tire move water? It has channels for water to flow through. Look at your sedan tire and you'll see channels: channels that run around the tire and channels that flow across ... read more
