A tire inspection is relevant whenever you pay for a Toyota Corolla--one of the most accepted compacts in the U.S.--or assistance the one you already own. Owing to tire defects are a determined safety hazard, perform these tests monthly and at the day one of every spread out coerce, according to the Governmental Highway Traffic Safety Government (NHTSA). Universal tire checks protect both you and other drivers from accidents, injury and yet annihilation.
Instructions
1. Attain approximately bourgeois tire defects. Damaged inner liners, cracked or dried edges, bubbles, leaks and tread separation are all serious warning signs. If you see any of these problems when car shopping for a new or used Corolla, make sure the dealership replaces the damaged tire before you buy the car.
2. Check the pressure of each tire with a tire gauge. For most Toyota Corolla models, the optimal pressure is 30psi. At each routine inspection, fill the tire with air if it's lower than this amount and if you hear a hissing sound or the same tire has low pressure consistently, there may be a leak. See "Use a Tire Pressure Gauge" under Related eHows.
3. Examine each tire separately for other defects by removing the tire to get the best view.4. Inspect the tire's tread and sidewalls. If the tread is pulling away from the main body (separated) or the sidewall has a bulge, your tire is a prime candidate for blowouts and rollovers, which causes accidents.5.
Loosen each lug nut and then raise up that part of the vehicle with a car jack. Finally, take off the nuts and detach the tire. Repeat Steps 3-7 for the other three tires, once you complete Steps 4-7 for the first tire.
Look at the edges and inner liner. A dry or cracked edge indicates dry rot, while a separated inner liner means the tire is defective.
6. Perform the "bubble test" for tire leaks. Besides a hissing sound and consistent pressure loss, you can also check for them visually. Inflate the tire and spray soapy water on it. If you see bubbling, there's an air leak.
7. Put the tire back on after you've inspected it. Tighten the lug nuts with the wrench and lower the vehicle using the car jack.
