Frequently Asked Questions(FAQs)

Q1. Can You Mix Air and Nitrogen?

<p>If your tires are already filled with nitrogen and their pressure is low, topping them off with air is acceptable. After all, air is 78% nitrogen, so using compressed air in tires that have previously been filled with nitrogen will not harm them.</p>

Q2. Advantages of Nitrogen

<p>Nitrogen molecules are larger than oxygen molecules, which means nitrogen escapes more slowly through the inner liner membrane used to retain air. The process of air escaping is known as permeability. This can mean tires maintain their correct pressure longer with nitrogen. Nitrogen's dryness makes it more stable than standard compressed air. In contrast, the compressed air in your tires contains water vapor. This water vapor might promote corrosion in some wheels (and tire pressure monitoring systems (TPMS) if your vehicle is equipped with one), and water vapor pressure fluctuates with temperature changes. This means tire pressures may vary more as ambient temperatures rise and fall than they would with nitrogen-filled tires.</p>

Q3. Where can I get a warranty booklet?

<p>You can download a full warranty booklet from our “Tire Warranties” section located here.</p><p>If you have further questions concerning Tire Warranties please contact Technical Services at 1-800-847-3272.</p>

Q4. What do I need to know about the aspect ratio and diameter of a tire?

Q5. What is the difference between an OE tire warranty and replacement tire warranty? What is usually included/excluded in each?

<p>The primary difference for Bridgestone or Firestone-brand tires is that Original Equipment tires are not covered by a limited mileage warranty, while several of the Replacement tires are. An eligible OE tire that becomes unusable for any reason within the manufacturer’s control may be covered up to six (6) years from the date of vehicle purchase. An eligible Replacement tire may be covered up to five (5) years from the date of tire purchase. Several Bridgestone and Firestone Replacement passenger and light truck tires also come with a 90 Day Buy and Try Guarantee. Exclusions from the limited warranty include, but are not limited to, damage from road hazards, improper maintenance, damage from chemicals and improper repairs. For a full list of coverage and exclusions, as well as the complete list of terms and conditions, refer to the applicable Bridgestone Firestone Warranty Manual.</p>

Q6. What is the difference between the O/E tire on my vehicle and a replacement tire?

<p>Original Equipment tires are engineered to meet specific requirements set by the car maker. Replacement tires are designed to provide the performance and treadwear most drivers expect for a particular type of tire.</p>

Q7. Disregarding mileage, how long is the life of a tire?

<p>Bridgestone follows the recommendations of the industry associations regarding tire life and inspection guidelines. We recommend that, in addition to regular tire inspections, customers have their tires inspected by a qualified tire service person after five (5) years of use to determine if the tires can continue in service. It is recommended that spare tires be inspected at the same time. Further, even when tires appear to be usable from their external appearance or the tread depth may have not reached the minimum wear out depth, it is recommended that all tires (including spare tires) that were manufactured more than ten (10) years previous be replaced with new tires.</p>
