Picking the Right Tires in Sierra Vista

Shopping for tires in Sierra Vista can be bewildering because there are many choices. Let's simplify. There are four main classifications of tires, each designed for different purposes.

First off, there are summer tires. Those who buy summer tires in Sierra Vista are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on AZ roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn't set up for snow and ice.

Next comes winter tires. Sierra Vista people buy winter tires because they still like performance driving when it's cold and slippery on AZ roads, so they need a tread design that'll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designed to handle well in severe ice and snow conditions.

The third category is all-season tires. Most new cars in Sierra Vista showrooms come with all-season tires. This is a tire that is designed to be used all year round. The tread design and rubber compound is a compromise that won't give you the extreme capabilities of summer or winter tires; but if you're driving and weather conditions aren't at the extreme ends of the range, all-season tires might suit you just fine.

The last category is what you might have on your SUV or pickup. All-terrain or off-road tires are designed for both highway and off-road use – a tire that gets good traction in the dirt and on off-road obstacles, but still performs well on paved Sierra Vista roads.

Choosing the right tire is important for Sierra Vista car owners. Talk with your Arizona Auto and Radiator Repair tire professional about your driving requirements and receive valuable guidance on tires that will meet your needs.

Tracking True in Sierra Vista: Wheel Alignment

At Arizona Auto and Radiator Repair, we occasionally see severe tire damage that could have been prevented with proper wheel alignment. During a Arizona Auto and Radiator Repair alignment service, your vehicle is put on an alignment rack where the tires, steering and suspension parts are inspected for problems. Then the alignment is charted and checked against the vehicle factory settings. Adjustments are made to bring the wheels back into alignment. This gets all four wheels moving in precisely the same direction.

If you don't remember hitting a pothole, how do you know if your wheels are out? The most obvious sign is that your vehicle pulls to one side. Also, your steering wheel may not be centered when you're going straight. If you're in the habit of checking your tire wear regularly, you may notice the edges of one or more tires rapidly wearing down. You should have your Sierra Vista auto service center look it over. Of course, if you've been in an accident, you should get your alignment checked.

It's not surprising that a forceful impact can seriously knock tires out, but remember that a series of smaller ones can add up. That's why your vehicle manufacturer recommends periodic alignment checks. If your vehicle owner's manual doesn't advise a specific interval, once a year might be appropriate. Check with your Arizona Auto and Radiator Repair service advisor. As with most other preventive maintenance services, the cost of the alignment is a heck of a lot cheaper than having to purchase new tires earlier than expected.

Power Steering Service in Sierra Vista

Most Sierra Vista drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine; a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea for Sierra Vista drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owner's manual for the right type - or just ask your friendly and knowledgeable pros at Arizona Auto and Radiator Repair in Sierra Vista.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so Sierra Vista drivers need to replace it from time to time. Many vehicle manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the car maintenance schedule for many of us. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your technician at Arizona Auto and Radiator Repair will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some  warning signs of trouble with your power steering: It's harder to turn the wheel, there's erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump quickly.

Other steering components can be bent or damaged from wear or hard knocks: ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear and an off-center steering wheel. An annual alignment check at Arizona Auto and Radiator Repair in Sierra Vista will reveal bent or damaged steering components.

Most SUV's, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. The team at Arizona Auto and Radiator Repair also recommends the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners' manual maintenance schedule. It's usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Sierra Vista area, the bearings will need service more often.

Regular Schedule or Severe Service Schedule at Arizona Auto and Radiator Repair?

Today's Arizona Auto and Radiator Repair article focuses on severe service maintenance. Many Sierra Vista drivers are not aware of them and yet there are also very vocal advocates in AZ who think that severe service schedules apply to everyone. Somewhere between a complete lack of awareness and the dire blanket statements lies a reasonable approach to severe service maintenance at Arizona Auto and Radiator Repair.

To back up a little, vehicle owner's manuals have schedules for preventive maintenance: things like oil changes, transmission service and so on. They say you should change your oil after a certain distanced traveled or after so many months. Sierra Vista drivers understand this very well. What they may not know is that there are actually two service schedules: the regular schedule and the severe service schedule. The mileage and time intervals are lower on the severe service schedule.

Now when you hear 'severe service,' you may think it doesn't apply to you because you don't feel your driving conditions are severe or extreme – it's just normal everyday driving in the Sierra Vista area. So let's list some of the conditions that classify as severe so that you can make the judgment on your own driving.

Before we start the list, here's a point of contrast that definitely is not severe driving. Driving down your nearest AZ interstate at the highway speed limit on a 75 degree F/24 degree C day loaded only with your passengers. This is an easy trip for your vehicle: your engine is loafing along at low RPMs, no heavy loads to pull and moderate Sierra Vista temperatures. Now let's look at some severe service driving conditions.

Most trips around Sierra Vista are less than four miles/six and a half kilometers. When your vehicle engine cools down, moisture condenses in the engine. This water in the oil doesn't get a chance to evaporate on short trips because the oil doesn't get hot enough. A lot of short trips in your vehicle means a lot of water build up. And water in the oil leads to the creation of sludge which can damage the engine. Changing the oil more frequently keeps sludge from building up. By contrast, highway driving warms the engine up and gets the water burned off.

Here's another example. Most trips around Sierra Vista are less than 10 miles/16 km and outside temperatures are below freezing. This is the same reasoning, but in very cold AZ weather it takes even longer for the oil to get hot enough to evaporate the water, hence 10  miles/16 km as opposed to 4 miles/6.4 km.

Next, you drive in very hot AZ weather. The hotter it is outside, the more cooling the engine, transmission, brake fluid and so on becomes. The environment in which the fluids reside is more hostile, and the fluids simply break down faster. Therefore, the lower change interval.

Another: driving at low speed most of the time. Every vehicle engine has what's called its power band. This is a range of RPMs in which it's most efficient. Low speed driving doesn't keep the engine in its power band so it's working harder. This is one of the reasons that ratings are worse in downtown than on the highway.

Stop and go driving in Sierra Vista is another severe service condition. You're always accelerating, which works the vehicle engine and transmission harder. Then you're stopping, which works the brake fluid harder, causing it to get very hot. Highway driving, on the other hand, requires far less horsepower to maintain its speed than getting a stationary vehicle from a stop light up to 25 mph/40 kph. A lot of this and you'll need to follow the severe service schedule.

Also on the list is operating your vehicle in dusty, polluted or muddy conditions. Obviously, your engine air filter and cabin air will get dirty faster and need to be changed more frequently as will your breather element. Some of this dust and dirt will make its way into your fluids. They will simple get dirty faster and won't protect the components as well as fresh fluids.

Finally, you're driving under severe conditions in Sierra Vista when you tow a trailer, regularly carry heavy loads or carry a car-top carrier. This is pretty obvious. You'll spend more time in lower gears so the engine and transmission work much harder and create more heat. Brakes will be more stressed stopping the heavier loads.

Sounds like most of us in Sierra Vista operate under severe driving conditions at least some of the time. How can Sierra Vista drivers know which schedule to follow?

Think of it as a spectrum with "always driving under severe conditions" on one end and "never driving under severe conditions" on the other end. Some will be at one extreme or the other, but most of us will fall somewhere in between.

Carefully think about your driving conditions and decide if you should do your preventive maintenance closer to the severe service recommendation or the regular recommendation. Of course, your Arizona Auto and Radiator Repair service advisor can help you with your decision.
