Each time that you drive over a pothole or hit a curb, you are doing damage to the front end and causing serious tread issues with tires. The result is the tires wear faster and you are going to increase the risk of having a blowout while riding at high speed. Getting a front end alignment can help extend the life of the tires.
Taking time each week to really inspect the treads on each tire will go a long way in reducing the chances that your car tires experience a serious issue on the highway. Take a close look for things like cracks and bulges, or areas where the tread is coming free from the rest of the tire. Don't ignore the trouble, have a tire tech see if the issue warrants further investigation.
