Hapa unaongelea kuisha kwa tairi linalotumika barabarani (sio lililopo kwenye gari), Mileage inamaliza tairi tena hapo ni tairi linaisha kweli kweli regardless ni miaka mingapi.What Happens to a Tire as It Ages?
Sean Kane, president of Safety Research & Strategies, Inc., compares an aging tire to an old rubber band. "If you take a rubber band that's been sitting around a long time and stretch it, you will start to see cracks in the rubber," says Kane, whose organization is involved in research, analysis and advocacy on safety matters for the public and clients including attorneys, engineering firms, supplier companies, media and government.
That's essentially what happens to a tire that's put on a vehicle and driven. Cracks in the rubber begin to develop over time. They may appear on the surface and inside the tire as well. This cracking can eventually cause the steel belts in the tread to separate from the rest of the tire. An animation on the Safety Research & Strategies Web site shows how this happens. Improper maintenance and heat accelerate the process.
Every tire that's on the road long enough will succumb to age. Tires that are rated for higher mileage have "anti-ozinant" chemical compounds built into the rubber that will slow the aging process, but nothing stops the effects of time on rubber, says Doug Gervin, Michelin's director of product marketing for passenger cars and light trucks.
Mimi nazungumzia hiyo immediate expiry date ya 4 years kama perishable food ni angalizo tu. Kinachodetermine zaidi kuisha kwa tairi ni mileage.
