Minnesota Balance: Wheel Balancing and Tire Rotation
Date: August 24, 2010 11:47 AM - Category: Tires and Wheels
Everyone in the Apple Valley area wants our tires to last as long as possible. Two ways to maximize tire life are wheel balancing and tire rotation.
When wheels are out of balance, they wobble a bit. That makes the tires wear in a cupping pattern. And they vibrate. To fix this, your service technician at Valley Auto Care puts weights on your wheels to balance them out. If a front wheel is out of balance you’ll feel it in the steering wheel. If it’s a rear wheel you’ll feel it through your seat.
That brings us to tire rotation. The front tires on a car wear out more quickly than the rear tires. As they push through turns from Apple Valley to Rosemount, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.
Proper tire inflation will also help your tires last longer. Under-inflated tires wear excessively on the shoulder and may even overheat. This could cause tire damage or a blow out. Over-inflated tires wear to fast in the middle.
Four wheel drive trucks and SUV’s tend to wear their tires more unevenly so rotation is even more important with them. Give us a call to get our recommendation on your car.
See your owner’s manual or ask your service technician at Valley Auto Care for your recommended tire rotation schedule. It’s usually every 5,000 to 8,000 miles.
Tires cost a lot and they are one of the most critical safety components on your vehicle. Take care of them and they’ll take care of you.

Maintenance Free Myth
Date: August 17, 2010 10:11 AM - Category: Maintenance
Sometimes we hear people say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's cars and trucks are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most folks don't realize how high tech automotive fluids have become. Fluids like, engine oil, transmission fluid, coolant and brake fluid.
Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and miles march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories from AutoNetTV staff members to emphasize the importance of getting things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and budget. But they are tales of a stitch in time saves nine.
The first comes from a staffer who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated on the highway and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been exchanged - just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundred of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.
Another story involves the true cost of skipping an annual inspection. Our staffer took his SUV in for the Minnesota safety inspection to renew his registration. At the inspection station, he learned that the law had changed and that his newer rig only required an inspection every two years. He was very happy to save the $45 bucks. The problem was, his rear brake pads were very worn. Two months later, it was bad enough that he could hear the grind - over the radio, DVD player and the kids. He took it in to get the bad news. Both of the rear brake rotors were damaged. The left one could be resurfaced. The right had to be replaced. So saving a few bucks on his safety inspection turned into an extra $500 over what brake pad replacement would have been. Moral of the story: don't skip your annual inspections. The irony is that many Apple Valley service centers would have done a brake inspection for free.
Next: a teenage daughter and a curb. Daddy's little princess smacked a curb when she turned into a shopping center and popped the tire. The problem came when Dad didn't get an alignment. The impact was hard enough to ruin the tire - so it was hard enough wreck the alignment. But instead of an alignment after the first tire, Papa ended up buying a second tire a few months later - and then an alignment.
Situation: son and wife with cars from the same manufacturer with essentially the same engine. Our staffer checked the son's maintenance schedule and saw that it needed a timing belt replacement at 90,000 miles/145,000 km. He had it done - it cost several hundred dollars. His wife's car had about 60,000 miles/97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 60,000 mi/97,000 km. At 63,000 mi./101,000 km, the belt snapped on the interstate. The valves all crashed down into the cylinders at high speed and the entire head was shredded and had to be replaced. The cost: several thousand dollars. Does he wish he had checked the maintenance schedule? You bet he does - every time he passes a big-screen TV.
We're talking about taking care of little things before they become big things. And when you take care of the little things, your car runs better and is more economical to operate. Remember to save those maintenance records. It'll show potential buyers that you've taken care of your vehicle and it will help you get a better price. Or when you buy a used car, check those records. If there aren't any, assume that the maintenance hasn't been done and take it to your Burnsville or Rosemount service center for an inspection. Take care of unperformed maintenance sooner rather than later.
Tire Maintenance In Rosemount
Date: August 5, 2010 2:44 PM - Category: Tires and Wheels
With the recent focus in Rosemount on improving fuel economy, we've been told how important it is to maintain our tire pressure.
Everyone in Rosemount knows that tires wear out, but we all want to make them last as long as possible because they're fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly.
Some people in Rosemount wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn't. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Every vehicle in the Rosemount area has a sticker on the driver's side door jamb that tells you the manufacturer's recommended tire pressure. This recommendation is an integral part of the vehicle's suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it's important to follow it.
What else do we need to know about tire maintenance? Tire rotation and balancing are very important. Let's start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. We rotate the tires so that they all get to do some duty on the front and they'll all wear evenly over their life.
For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it'll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can't be rotated at all. Your owner's manual will have details for your car.
How often should you rotate your tires? Your owner's manual will have a recommendation. Your service advisor at Valley Auto Care can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles.
You know, some people don't think new tires need to be balanced. What they aren't taking into account is the wheel. Between the wheel and the tire – even a new tire – there's enough variation to require balancing.
When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely in order. When a tire's out of balance, it's actually hopping down the road. You'll feel the vibration through the steering wheel if a front tire's out of balance and through your seat if it's a rear tire.
Proper wheel balance promotes tire life and increases safety. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted.
Also, always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that's where you need the most traction to avoid spinning-out.
