Ako su gume pravilno skladištene onda te 2 godine ne znači ništa posebno jer nisu vožene. To se preporuča 5 godina tek nakon što su gume montirane na auto i vožene jer se onda skine onaj "zaštitni" sloj gume.

Pa nije isto vožena i nova guma, naravno.

Ali ako usporediš gumu staru 2-3 tjedna i gumu staru 2 godine, bez obzira je li vožena ili ne, nema iste karakteristike. Starija guma je tvrđa, uvijek. Čista kemija. Gume su u dodiru s kisikom, a čestice kisika djeluju na čestice gume na način da ih usporavaju i guma postaje sve "tromija" i tvrđa.

Just because a tire is unused doesn't mean it's new. In a number of instances, consumers have purchased "new" tires at retail stores only to find out later that they were manufactured years earlier. In addition to having a shorter life on the road, a tire that's supposedly new but is actually old may be past its warranty period.

If you buy tires and soon after discover that they're actually a few years old, you have the right to request newer ones, Zielinski says. Any reputable store should be willing to make amends. "It is fair for a consumer to expect that 'new' is not several years old," he says.

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.
