Inspect Tire Condition Regularly

Tires are an integral part of any car, and they need regular inspection in order to ensure they are still safe for use on the road. Make sure you check all four tires regularly for any signs of wear or damage such as bulges, cracks, or bald spots; also look for uneven tread wear which could indicate misalignment or suspension problems.
