Why are my tires cracking? Cracks in a tire are often due to the age of the tires. As tires get older, the rubber gets brittle, and cracks will start to form. Once the tires are cracked, you must replace the tires. Tires can also have uneven wear. Uneven wearing of tires is typically due to worn suspension parts. This can include the shocks, struts, or ball joints. Leaking struts are the most common cause of uneven tire wear. The alignment can also cause edgewear on tires if it is off. When you replace your tires, your vehicle should be aligned. This will ensure the suspension is in manufacture specification. Call today to schedule an appointment to have your tires checked!
