TIRES FAQs

How often should I get my wheels aligned?

Alignments should be performed when you get new tires or every other oil change. Anything like potholes, dirt roads, and regular driving wear can affect your vehicle’s alignment. By getting your wheels aligned routinely, your car will perform better and longer. You can even increase your fuel-efficiency. If it’s been awhile since you’ve had your wheels aligned, we suggest making an appointment soon.

How long can I drive on a spare tire?

Spare tires cannot perform the same as regular tires. You should never drive over 50mph on a spare, or over 50 miles. At Graff Bay City we can patch you tire or get it replaced quickly so you can be back on the road safely in no time.

How do I know what my tire PSI should be?

PSI stands for pounds per square inch of air pressure. You can find your vehicle’s recommended PSI on the inside of your driver door or in the owner’s manual. Never go by the PSI that’s on you tires, because that is the max PSI the tire can hold. If you’re unsure about your tire pressure, give us a call and our tire experts at Graff Bay City can help you out.

Why does my tire pressure light go off when it’s cold outside?

Cold weather compresses the air in your tires and can cause your sensor to go off. A lot of times you might notice that in the morning your light will be on and during the day it will be off. That’s because the air has warmed up through the afternoon. If your tire pressure light turns on, you can always bring your vehicle into our service center and we’ll check your PSI to make sure you’re good to go.

How do I know which tires to buy?

When replacing one or two tires you should always get the same tires that you already have on your vehicle so they all match. If you’re replacing all of your tires you have two options. You can either get the same brand that you had before, or you can ask the tire experts at Graff Bay City what they recommend for your vehicle. It’s important that you find the right tires for your vehicle that meet your driving needs.

Why are tire alignments important?

Tire alignments ensure that your tires remain perpendicular to the road and parallel to each other. By having your tires aligned properly your tires will wear evenly, saving you money in the long run. By routinely performing tire alignments and checking your tire pressure, you’ll improve you car’s fuel-efficiency and drive safely on the road.

When should my tires be replaced?

There are a number of signs to look for if you’re thinking about replacing your tires. Look for warning signs like major tread wear, irregular tread wear, abnormal bulges, or cracks in the sidewall. To check your treads, you can use the “penny test” (Check the next FAQ). Another important factor you may want to consider is the traction you get in snowy and icy conditions. If you don’t feel safe driving in these weather conditions it would be beneficial to invest in winter tires.

How can I check my tire’s tread?

There’s a very easy and quick way to test your tires’ tread and it’s called the “Penny Test”. Here are the instructions:

  • Place a penny in the lowest tire groove with Lincoln’s head pointing down into the tire.
  • Move the penny along the groove.
  • If any part of Lincoln’s head in NOT covered that means you tire’s tread is worn too much and you don’t have the proper grip you need on the road. If this happens you should being your car in to get your tires inspected and replaced.

Why is it important to have the right tire pressure?

Having the right air pressure in your tires helps your vehicle perform at its best. With the right air pressure, your car will handle much better, your tires will last longer, and it can help you save on fuel.

How often should I get my tires rotated?

An average rule for getting your tires rotated is every 6,000 miles or every other oil change. If you don’t get your tires rotated they can wear unevenly.

What is the main cause of tire damage?

A number of things can cause tire damage, but the most common one is improper inflation. You can check your inflation with a tire gauge, which we recommend keeping in your glove box at all times.

WIPER BLADES FAQs

How do I know which windshield fluid I should use?

There are two types of windshield fluid you can use in your vehicle. The first type is a diluted formula, which is the most common. The other type is a concentrated formula that you need to dilute with water in your washer fluid tank. The important thing you should pay attention to is the recommended temperature for the solution. Does the temperature that is listed on the label match the weather you’re driving in? If you need assistance with refilling your windshield fluid, or you’re having a hard time choosing which one you should use, come into our service center at Graff Bay City and we’ll take care of you.

Where can I find the size of my wipers?

Wiper sizes are different for each vehicle make and model. A lot of times the left and right wiper will also be different sizes. To ensure you get the right wiper size, check your owner’s manual, look online, or ask one of our service experts at Graff Bay City.

How do I know if my wiper blades need to be replaced?

There are a few simple signs to look for when your wipers need to be replaced –

  • Wipers leave streaks on your windshield
  • The rubber on the wiper is cracked or dried out
  • The rubber strip is completely gone
  • Wiper is damaged beyond repair

If your wipers are not clearing your windshield enough to where you can see the road properly, they most likely should be replaced. If any of the signs in the list above occur, come on into our service center and we’ll replace your wipers for you.

BRAKES FAQs

How often should I get my brakes checked?

As a general rule, your brakes should be checked every 5,000 miles or every 5 months – whichever comes first.

If your daily commute is stop and go traffic in rush hour, your brakes could wear faster. On the other hand if you don’t drive that often your brakes will not wear as fast and can possibly go longer in between checks.

Why does my steering wheel shake when I brake?

Your steering wheel shakes when you’re braking because your brake rotors are most likely warped, or they have become too thin to distribute the heat correctly.

Why are my brakes squealing?

Squealing sounds from your brakes does not always mean something is wrong. However, you should pay attention to when the squealing occurs and how often. If the problem consistently occurs, you could have bad brake pads or rotors. Just to be safe, we suggest you come into our service center and have our experts take a look so you can avoid any future damage.

OIL CHANGES FAQs

How often should I get my oil changed?

The recommended time between oil changes is every 3,000 miles. Always double-check your owner’s manual to see what they suggest as well.

Should I consider synthetic oil?

Synthetic oil works well in cars that are supercharged, turbocharged, or have a high output. Your vehicle may also benefit from synthetic oil if it drives in extreme weather or is used for towing. Synthetic oil is more expensive than mineral-based oil, but it prolongs the time in between each oil change and improves your fuel economy.

Why does my engine oil look milky brown?

If you notice that your engine oil looks milky brown you should have it inspected by a service expert immediately. This could be a sign that you have a blown head gasket, a cracked casing, or a failed transmission cooler.

GENERAL CAR CARE FAQs

How do I know which fuel type is better for my car?

Your car’s fuel type is dependent on the make, model, and trim level. The best way to figure out which fuel type you should use is to check your owner’s manual.

When packing an emergency kit make sure you have tools, a first aid kit, jumper cables, flashlight, extra clothing, tire pump, and roadside flares. Some extra things you may want to pack are kitty litter for snow traction, a phone charger, and extra cash.

How does my driving affect my vehicle’s performance?

Every person has his or her own driving style and it usually depends on what your daily commute looks like. Being aware of your driving style is important because you can make changes and possibly prolong the life of your vehicle. For example, if you’re driving in rush hour traffic and slam on your brakes a lot, you’ll wear them out a lot quicker. Or if you’re driving over a road with lots of potholes you might want to change your route if possible because your vehicle alignment will be affected.

Why is my car having issues starting in the cold weather?

Your vehicle could have a problem starting for a few reasons. The first is your oil thickening, making it hard for your engine to spin. Another reason could be a bad fuel mixture or the lack of fuel. In winter it’s suggested that you always have at least a quarter tank of gas in your tank. Also, you could have a weak battery. If this is the case, you should come into our service center to get it replaced.

How long should I warm up my engine before driving in the winter?

A lot of people assume that in the winter months, having your vehicle idle will warm it up quicker, but in any month your car should only idle 30 seconds or less to warm up. Your vehicle will actually warm up quicker by being driven. In the colder months you should drive more gently in the first 10 minutes though to make sure your engine has enough time to warm up completely.

What should I do if my engine temperature gauge starts to rise too high?

If your temperature gauge rises too high you need to cool off your engine as quickly as possible. The first thing you should try is to turn off the air conditioner. Your air conditioner can actually cause a lot of strain on your engine. If that doesn’t work you should turn your heater up because this will pull heat away from your engine. If neither of these solutions work, you should pull over and call for assistance.

What does it mean if my check engine shows up on the dashboard?

Your vehicle has a number of sensors used to detect problems that may arise. If any of the components in your vehicle aren’t working your check engine light could turn on from those sensors. If your light goes on, we encourage you to come into our service center so we can find the problem and fix it.
