I did some research before ordering the fenders. It rained almost every day, and living on a dirt road didn't help. I had to clean my Hummer H3 all the time because the dirt got to the windows. When I read another review that said they were wide I thought I'd give them a try. My tires are wide and I wanted something nice to cover up with. My husband put them on in no time and he said they came through easily. Then I waited and there was no rain for a couple of weeks. Well it finally started raining and I went outside just to try on fenders. I am very pleased to report that I no longer have mud on the side of my white lobster. I'm not sure why they would make a Hummer without the ones already installed. You look great, just like factory. The delivery was so fast. I love her!
