At least once a month, inspect your tyres closely for signs of uneven wear. Uneven wear patterns may be caused by improper inflation pressures, misalignment, improper balance, or suspension neglect. If not corrected, further tyre damage will occur. If you discover uneven wear, bring your car to your nearest Toyo dealer. In many instances, the dealer can correct the problem so you can continue to use your tyres.
When the tread is worn down to one-sixteenth of an inch or 1.6mm the tyre is worn out and it is time to replace it. Built-in tread wear indicators, or "wear bars," which look like narrow strips of smooth rubber across the tread, will appear on the tyre when that point of wear is reached.
Look for any stones, bits of glass, metal, or other foreign objects in the tread or sidewall. These may work deeper into the tyre and cause air loss. If any tyre continually needs more air, have your Toyo dealer
check to find out why it is leaking. Damage to the tyre, wheel, or valve may be the problem.
