Tire Care FAQs

Can I put 2 different size tires on my car?

It depends on vehicle, axle, tire sizes and patterns, etc. Please visit your nearest GT Radial retailer for more information.

How do I know when I need to replace my tires?

The tire is considered worn out when any main groove is worn to 2/32nds or below, which is when the tire rib is at the same level as the wear bar. To inspect your tires, please take to a local GT Radial retailer near you.

Why do I need to rotate my tires and how often should I have them rotated?

Tire rotation can be beneficial in several ways. When done at the recommended times, it can preserve balanced handling and traction and even out tire wear. Our Mileage warranties require tire rotation to keep the warranty valid. We recommend that tires be rotated every 3,000 to 5,000 miles even if they don't show signs of wear. Tire rotation helps even out tire wear by allowing each tire to serve in as many of the vehicle’s wheel positions as possible. Remember, tire rotation can’t correct wear problems due to worn mechanical parts or incorrect inflation pressures.

What is the recommended air pressure for my tire?

The recommended air pressure can be found on the tire information placard on the vehicle door edge, door jam or glove box door. You can also refer the vehicle owners manual. If it is a plus size fitment, please consult a GT Radial retailer for proper tire PSI recommendation.

Why is checking the air in my tires so important and how often should I check them?

You should check your air pressure once a month. However, to provide a greater level of safety, the tires should be viewed as you walk toward the vehicle every day. Underinflated or overinflated tires may result in poor handling, uneven treadwear and increased fuel consumption.

When should I check the air pressure on my tires?

It is best to check the pressure in your tires when they are cold, that is after the vehicle has been parked for at least 3 hours or driven less than 1 mile. It is recommended to check your inflation pressure in the morning after the vehicle has been parked overnight.

Can I inflate my tires with nitrogen?

"Yes, since nitrogen is an inert gas. It is simply dry air with the oxygen removed (air contains nearly 78% Nitrogen). The physical properties of nitrogen reduce the pressure loss due to the natural permeability of the materials of the tire. Unfortunately, there are other possible sources of leaks (tire/rim interface, valve, valve/rim interface and the wheel) which prevent the guarantee of pressure maintenance for individuals using air or nitrogen inflation. Tires manufactured by GT Radial are designed to deliver their expected performance when inflated with air or nitrogen, as long as, the user respects the pressures recommended by the vehicle manufacturer on the vehicle's placard or by GT Radial. Regular pressure maintenance remains critical whether they are inflated with air or nitrogen because under-inflated tires lead to the following conditions: reduction in wet traction capability increased sensitivity to road hazards reduction in treadlife increased fuel consumption reduction in tire life due to excessive heat from over deflection "

Is there a break-in period for my new tires?

For better tire performance, it is recommended that new tires be driven at least 100 miles on paved, dry road surfaces to expel any release agents applied during the production process.

How long should my tires last?

There are numerous factors determining the length of service tires provide. Mileage will vary based upon the variety of road and climate conditions, driver habits, tire maintenance, tire construction and tread compound.

If I only purchased two new tires, where should I mount them?

The new tires should always be mounted on the rear axle of your vehicle. Make sure that the new tires are the same size and type as your current tires.
