Good tread does not always mean a safe tire. Rubber ages from oxygen, heat, and sun exposure, which slowly hardens the compound and weakens the bond between rubber and internal cords. Grip falls off most on cold, wet mornings and during emergency stops. Here is how to judge tire age accurately and decide when to replace them, even if the grooves still look deep. Why “Plenty of Tread” Can Still Be Risky A tire’s chemistry changes over time. As rubber cures and dries, the tread blocks lose flexibility, sipes stop biting in the rain, and tiny surface cracks open around letters and at the base of grooves.

Pedal Feel Is Not What It Used To Be Your foot knows your car. When the pedal starts to travel farther or feels softer when you hold steady pressure, something has changed in the hydraulic system. Air trapped in a line, moisture in old fluid, or a master cylinder that is beginning to bypass can all make the pedal feel spongy. If the pedal sinks slowly at a red light, that is a sign to park the car and schedule service, since internal leaks will not heal themselves. 2. New Noises That Do Not Fade A light squeal on the first few stops of the day can be normal when moisture flashes off the rotor ... read more
