15 Inflate the tire slowly, using no more than the recommended pressure. If you're installing a new tire you may hear a "pop" as pressure forces the bead into place. Old tires may not seat as forcefully, so don't be alarmed if yours gives you the silent treatment. Adjust pressure to the recommended setting and then locate the bead indicator on the tire. Some bead indicators are just a raised rubber strip, while others look like hash marks scribed into the tire. The indicator should be equidistant from the rim all the way around the wheel. If it isn't, try adding air; you can go as high as 45 psi. If the tire still won't seat correctly, release the air, lubricate the bead and try again. Once it's seated, adjust pressure to the manufacturer's recommendations.
