Frequently Asked Questions

Fuel Economy

What can I do to get better gas mileage?*

There are several no-cost ways to improve your gas mileage, starting with your driving habits. Make gradual starts and stops, maintain a constant highway speed, keep to 55 miles per hour and you will save tankfuls of gas over the course of a year.

Any other free tips?

Get rid of the excess weight that your vehicle carries. For example, tools, sports equipment, books, etc

How much can I save on gas by driving 55 miles per hour?

A lot. Driving 55 mph is 25% more fuel efficient than driving 70 mph. In other words, if you get 20 mpg driving 70 mph, you get 25 mpg driving 55 mph. Over 1,000 highway miles, you burn 10 less gallons of gas, a savings of $40.**

 

** Based on a gasoline price of $4 per gallon.

How much can I save by cutting out jack rabbit starts and stops?

10%

How much can I boost my fuel efficiency by keeping my tires inflated to the correct air pressure?

According to the Rubber Manufacturers Association (RMA), you can improve fuel efficiency by 3.3%, or $.09 a gallon, by keeping your tires at the correct pressure. Don’t wait for the TPMS warning light to come on!

How much difference can scheduled maintenance make?

You can get 2% better gas mileage by using the correct grade of oil. Changing a dirty air filter can boost your mileage 4%.

What about my vehicle’s fuel injection system?

In the 1980s, fuel injection largely replaced the carburetor to achieve an optimum air-fuel mixture. This resulted in better fuel efficiency and less air pollution. Your fuel injection system needs to be cleaned periodically to maximize fuel economy and minimize harmful emissions.

Is there anything I can do to get better gas mileage with my older car?

Many vehicles benefit from an engine tune-up, including replacing the air and fuel filters, spark plugs and spark plug wires, and PCV valve (positive crankcase ventilation valve).

What can Tire Warehouse do to improve my vehicle’s fuel economy?

Have our technicians check your alignment*** the next time you change or rotate your tires. Bringing your wheels back into alignment can boost fuel efficiency 0.5-10%.

Nitrogen Tire Inflation

Do I still need to regularly check the pressure on nitrogen filled tires or refill them?

Yes. While nitrogen helps you maintain proper tire pressure longer, nitrogen does not protect your tires from road hazards. Check your tire pressure on a regular basis. Never drive on under inflated tires. Tire Warehouse will check your air pressure for FREE!

Can air and nitrogen be mixed together?

Yes. If you must top off your tires with regular compressed air, it isn't a problem. By topping off a nitrogen-filled tire with air, you're only decreasing the effectiveness of the nitrogen in your tires. Return to Tire Warehouse for FREE top-offs or a FREE refill.

Will nitrogen affect the Tire Pressure Monitoring System (TPMS) on a vehicle?

Nitrogen enhances the reliability of a TPMS system by minimizing moisture in the tire. You'll have less frequent alerts from the TPMS system because your tires stay at optimum pressure longer.

Can I use nitrogen in my spare tire?

Yes. It is actually recommended because nitrogen inflation maintains adequate pressure longer. Insure a properly inflated spare at the time you need it most; fill all of your spares with nitrogen!

Tires

Why do I see so many different prices for the same tire?

When shopping for tires, it’s important to compare the total cost—including mounting, balancing, valve stems, TPMS transfer, tire disposal, and an alignment check. Tire Warehouse guarantees the lowest total price. Plus, free lifetime rotations on all tires that we sell.

How often should I check the air in my tires?

For safety and maximum tire life, check the air pressure in your tires at least once a month. Use an accurate tire pressure gauge. Don’t fill your tires by look. Every time you bring your car to Tire Warehouse, we inspect your tires and show you how they’re wearing. We would be happy to check and fill your tires for free anytime you’re in the neighborhood.

How much air should I put in my tires?

The recommended tire pressure varies widely by tire size and type. Consult your owner’s manual. The specifications of your original tires are also listed on a decal on the driver’s doorjamb or inside the glove box. If you buy a set of replacement tires, be sure to write down the new specifications.

How can I protect against blowouts?

The best protection against blowouts is to properly inflate your tires. Don’t let them get too soft; don’t overinflate them. Also, make sure you select a tire that is designed for your driving conditions.

How can I get more mileage out of my tires?

Check your tire pressure regularly, rotate your tires, and watch for signs of uneven wear, which can mean alignment problems.

How often should I rotate my tires?

Every 6,000 miles, or every other oil change, assuming you change oil every 3,000 miles.

Why buy winter tires?

Winter tires, also known as snow tires, are designed for superior traction on ice, slush, and snow. The rubber on winter tires is formulated to retain elasticity and grip in temperatures below 45 degrees. Standard radial tires harden at these temperatures and lose some of their hold on the road. Also, winter treads are designed with special snow patterns. Look for the mountain snowflake imprint for maximum confidence in winter driving.

How do I know when I need new tires?

When your tread wears down to 4/32 of an inch you start to lose significant traction on wet or snowy roads. A Washington quarter, placed upside down in the tread grooves at several points, is a handy gauge. You’re o.k. if the tread covers part of Washington’s head. To be legal in most states tires must pass the Lincoln penny test, a minimum tread depth of 2/32 inch. Manufacturer’s also place wear bars in the grooves between tire treads. When the tread is nearly flush with the bars, it’s time to replace your tires.

Why is tire tread depth so important to safety and handling?

On wet pavement, the tread grooves sluice water away from the tire where it makes contact with the road. A typical new passenger tire has a tread depth of 10/32 of an inch. When tread wears to even half that depth, the risk increases that your car will hydroplane—slide on the surface of standing water—especially at highway speeds. On snowy pavement, horizontal treads and small slits in the rubber called “sipes” bite into the snow. The deeper the tread, the better the grip.

How do I find quality replacement tires for my vehicle?

Come to the experts at Tire Warehouse. We will recommend the right tires, based on wheel size, vehicle make and model, expected load, how you drive, and other factors. We have thousands of tires in stock, and ready for you.

What size tires should I buy?

Tire size and other important information are imprinted on the tire sidewall.

What’s the speed rating on my tires?

This information is imprinted on the tire sidewall.

How do I use the Uniform Tire Quality Grade (UTQG) to make an informed tire purchase?

Tire grade ratings are intended to provide a simple way for you to compare tires. The ratings, imprinted on the tire sidewall, are based on tests under controlled conditions. The federal government specifies the tests, but manufacturers assign the temperature, traction, and temperature ratings.

My ride is quite rough. What can I do?

For a smooth ride, tires must be balanced properly. Also, some tires ride better than others. Every tire is a compromise. Tires with a long tread life have a harder ride. Tires with a softer ride wear faster. Visit Tire Warehouse for tire balancing and recommendations on the best replacement tires for your road conditions and the way you drive.

My car pulls to one side. Could this be a problem with one of my tires?

Possibly. A very soft tire can cause your car to pull to one side, but this is a very unsafe situation. Your car could also be out of alignment. Stop by Tire Warehouse for assistance.

Can my flat tire be repaired instead of replaced?

Only punctures in the center treads are repairable. This is an evaluation for the professionals at Tire Warehouse.

How important is tire pressure to my fuel economy?

You can improve fuel economy by up to 5% by keeping you tires inflated to the correct pressure and using the right grade of motor, according to the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy. If you drive 12,000 miles per year and gas is $3 per gallon, that’s a savings of $72 per year, assuming your car gets 25 miles to the gallon.

TPMS

My tire pressure light is on, what should I do?

The Tire Pressure Monitoring System (TPMS) warning light means that at least one of your tires is underinflated by 25%. Check your tires with an accurate tire gauge and fill them to the correct pressure. Your nearest Tire Warehouse would be happy to do this for you for free. If you identified the TPMS symbol on your dashboard as a tire pressure warning, congratulations! A recent study by TPMS manufacturer Schrader, found that 46% of drivers did not know that symbol—a tire in cross section with an exclamation point inside—means low tire pressure. Tire inflation pressure monitoring systems (TPMS) were introduced in luxury cars in the late 1980s and federally-mandated on all new passenger cars and light trucks beginning with the 2008 model year.
