Care Tips for Maximizing Tire Life
Maximizing your Fleet's tire life has never been more important. Goodyear recommends the following actions be taken to safely maximize the life of your existing tires:
1. Check inflation regularly and maintain proper inflation levels;
2. Avoid foreign object damage by eliminating foreign objects from hangar floors and/or runways;
3. Increase the frequency of your aircraft tire inspections. Take immediate action to correct any issues discovered during inspections;
4. Prevent premature removals of tires. Replace tires only when they are fully worn, rather than when convenient due to scheduled maintenance of other landing gear components.
Below are additional resources to help.

INFLATION PRACTICES
1. CHECK DAILY OR BEFORE FIRST FLIGHT WHEN TIRES ARE COOL
2. CONSIDER AMBIENT TEMPERATURE EFFECTS ON INFLATION; A TEMPERATURE CHANGE OF 5°F (3°C) PRODUCES APPROXIMATELY ONE PERCENT (1%) PRESSURE CHANGE.
3. USE DRY NITROGEN GAS (SAFELY)
4. WHEN CHECKING INFLATION, REMEMBER PRESSURE IN A LOADED TIRE WILL BE ABOUT 4% HIGHER THAN AN UNLOADED TIRE.
5. ALLOW 12-HOUR STRETCH AFTER MOUNTING.
6. NEVER REDUCE THE PRESSURE OF A HOT TIRE. REMEMBER - 1% PRESSURE CHANGE FOR EACH 5°F (3°C)
7. EQUAL PRESSURE FOR DUALS
8. CALIBRATE INFLATION GAUGE REGULARLY
NOTE: Keeping aircraft tires at their correct inflation pressure is the most important factor in any preventive maintenance program.
Recommended Actions for Cold Tire Service Pressures
| Cold Tire Service Pressure | Recommended Action (If the tire potentially operated at this condition) |
| 100 to 105 percent of loaded service pressure | None - normal cold tire operating range. |
| 95 to less than 100 percent of loaded service pressure | Reinflate to specified service pressure |
| 90 to less than 95 percent of loaded service pressure | Inspect tire/wheel assembly for cause of pressure loss. Reinflate & record in log book. Remove tire/wheel assembly if pressure loss is greater than 5% and reoccurs within 24 hours. |
| 80 to less than 90 percent of loaded service pressure | Remove tire/wheel assembly from aircraft (See NOTE below). |
| Less than 80 percent of loaded service pressure | Remove tire/wheel assembly and adjacent tire/wheel assembly from aircraft (See NOTE below). |
| 0 percent | Remove tire/wheel assembly and adjacent tire/wheel assembly from aircraft. Scrap tire and mate if air loss occurred while rolling (See NOTE below). |
NOTE: Any tire removed due to a pressure loss condition should be returned to an authorized repair facility or retreader, along with a description of the removal.
