Last week I had the unfortunate experience of a puncture on my right rear tire. I ended up jacking up the car and replacing both tires. I looked at the front and realized that if this flat tire happened in the front I cant change it myself, because my jack does not go low enough to get underneath the front jack point (pinch weld) nor do I feel comfortable jacking my car up at this point. Does anyone use jack inserts, if so what kind? Also does anyone use bolt on jackrails? Any opinions would be greatly appreciated. Thank you.
