What causes cracks in automobile wheels?

Answer by  mechtech74 (692)

The main cause is age. It's possible your tires were stored for many years before installation. Typically, minor cracking occurs due to exposure to extremes of weather: hot sun, freezing climate, etc. This will be conspicuous if only showing on the outward facing side. Most manufacturers warrantee against cracks for 4 years. You may be due a pro-rate on replacements.
