Your Tires Can Be a Ticking Time Bomb
Drivers, especially in the hot and dry climate of Arizona, need to remember that a vehicle tire is made of rubber. Over time, all rubber degrades to the point where it is no longer usable. To illustrate, imagine a rubber band that gets left in a drawer for a few years. It becomes brittle and when you try to use it, it may likely snap in half. Unlike rubber bands, however, the degradation of rubber in tires may all be internal and NOT visible to the naked eye. As tires age, the adhesion of the steel belts may be compromised by as much as 75%, likely resulting in a tread separation, often at highway speeds. When this occurs, drivers often lose control of the vehicle with devastating results. Not surprisingly, this degradation process (known as thermo-oxidative degradation) is accelerated in hotter climates.
As of 2013, all major vehicle manufacturers in the United States, as well as Europe and Japan, warn about the risks of tire aging in their vehicle owner’s manuals. The word choice varies, but essentially all the manuals recommend replacing your tires once they reach 6 years old. But how do you tell a tire’s age? These answers are simple, but you have to know where to look.Since 2000, all tires sold in the United States have been required to include a full 12-digit DOT code on the sidewall of the tire.The last 4 digits of this code represent the manufacturing date of that tire -- the 2-digit week and the 2-digit year. For example, if your tire was manufactured in the 36th week of 2006, the 4-digit code would read “3606” – and if you had a tire that’s already that old, the vehicle manufacturers would all recommend that you replace it, regardless of remaining tread depth. This warning applies to spare tires, as well.
Only one side of the tire necessarily has all 12 digits of the DOT code. If that DOT code is mounted inboard, you may have to crawl under your vehicle with a flashlight. If neither side has a 12-digit DOT, your tire may have been manufactured before 2000 … don’t risk it – replace it.
Only buy new tires from a licensed retailer. Do not buy used tires, no matter how inexpensive they are. Even if they are less than 6 years old, used tires could already have serious internal damage that you won’t be able to see.
We always advocate replacing all four tires at once with tires that were manufactured within the last year or so. If for some reason you cannot replace all four tires, put the two new tires on the rear axle and put the two best remaining tires on the front axle. While this may seem counterintuitive, most experts agree that it is easier to maintain control of a vehicle during a front tire failure than a rear tire failure. Tires are also assigned a Uniform Tire Quality Grade (UTQG) rating. Generally this consists of a three digit tread wear rating, a letter grade traction rating – “AA”, “A”, “B” and “C”, and a letter grade temperature rating – “A”, “B” and “C”. The temperature rating represents that tire’s ability to dissipate heat. This consideration becomes more important if you drive in hot climates; especially at highway speeds and in a vehicle with a high center of gravity, such as a truck or SUV, the heat build-up in a tire is often a cause of tire failure. Many tire dealers have websites where you can input your vehicle year, make, and model to see the available tires for your vehicle.The best websites show the UTQG rating next to the tires.
Everyone in the industry agrees that if you have 2/32 of an inch or less of tread depth at any location, it is time to replace the tire.But many tires experience failures before the tread gets that low; accordingly, even if your tread gets down to 4/32 of an inch, it’s best to replace the tire.The “penny test,” as most of you know it, still works reasonably well to measure this depth. Stick Abe’s head upside down into the tread; if you can see his whole head, there’s not enough tread. Maybe because pennies are tough to find nowadays, most modern tires also have wear bars in the grooves of the tread; when the tread is worn to near the same level as the wear bars, it’s time to replace the tire. Some tires wear unevenly , so it’s important to look at the whole thing to make sure you don’t have any low spots. When a tire tread separates, it almost always begins where the tread is lowest.
Even if the tire is less than 6 years old and has enough tread, you still need to be on the lookout for cracking, chipping, or weathering (right) on the sidewall of a tire.This is most often seen when a car is parked in the sunlight, so that the sidewalls of the tires bake in the hot sun.A tire can fail because of sidewall damage as well, so be careful.
It is well publicized that tires can fail due to under inflation and over inflation; therefore, tire maintenance is critical to minimizing this risk.Industry experts recommend that you check tire pressure each month and, in addition, before you embark on a long road trip. To ensure proper tire inflation, refer to your vehicle manufacturer’s recommended tire pressure and not the range of tire pressure indicated on the sidewall of your tires.The manufacturer’s recommended tire pressure can be located in your owner’s manual, as well as your door placard usually located in the door jam of the driver’s door.
Especially if you are planning to drive at freeway speeds in Arizona, high quality tires are just as important to the safety of your passengers as wearing seat belts.As we approach summer long-distance driving season, now is the time to have a tire professional inspect your tires for age, tread depth, and other potential problems. The sign at your neighborhood tire shop which boasts a “Free Tire Inspection” is not just some trick to get you to buy new tires.If they recommend replacing your tires, use that money you are saving by not flying to your destination to get new tires and ensure your passengers’ safety.
Have a pleasant and safe summer driving season!

Is it legal to sell meat without the weight and cost per pound identified?
I was in a car accident. The other driver's insurance company has offered to pay about $1000 -$1500 less than the Kelly Blue Book value for my car. The insurance company will not release my car until I sign the title over to them. The insurance rep will not provide documentation of how they determined the valve of my car. The rental car must go back today and I can't buy other car like mine for the amount they are offering. Is there anything I can do?

We hired a landscaper and gave $2750 deposit for work to begin on August 24th. After several canceled appointments and no shows landscaper agreed to refund deposit. We waited 10 days for refund check and received a post dated check for 30 days into the future. What is our best course of action to get back our money. The company will not return calls or emails and we are worried they will stop payment or close account before we can cash the check
I went to a lawyer for my divorce. He quoted "about $1500.00, maybe a little more." Due to mistakes his people made the divorce took about 8 months. He is now billing me for over $10,000.00. There was no fighting between my former spouse and me, at all. He will not tell my why the cost is more than six times the original amount, and he is now adding interest of 18%.

I am a PhD student at a private university. My program was sold to me as a 3.5 year program. I started the program in February of 2015 and had a completion date of July 2018. This is indicated on my student loan document. Through 2016 and 2017 had been working on an approved dissertation. In January of 2018, (6 months prior to finishing) I was informed my dissertation was no longer approved and I would need to start a new one. This extends my program by more than a year. More loans, more work... This is a frequent tactic by this university. Brings them in a lot of money, learners lose
A company called to offer me leads and services and I paid them with my card. They never sent any leads or services and my card is still delaying my refund. They stole $4650.00 I'm a senior citizen 73 years old and my husband is 81, he still works because we are broke. I lost my job and have health problems.What can do to get my money back? Thank you.
I discovered AT&T has fraudulently been charging me a "dial-up" fee for my email account. The amount has been between $12.95 and $21.95 every month, and I've had broadband since 2005. I read an article about a lady in New Jersey who had the same problem and she successfully sued AT&T. I'd like to take them to small claims court, but I don't know who to send the claim to. Do I send it to the corporate office? Doesn't someone have to be named? How do I serve them notice?
