As with all other brand cheap plastic caps some break when fitted so order 1-3 sets. Return the cracked ones or leave the uncracked ones, you'll need more if you ever get new tires, balance or rearrange tires, change a flat tire, etc. Just for beauty before you sell or trade-in your car. Almost impossible to fit on a standard 14 inch steel wheel. I gave up and went to my tire shop. Took her technician and I, both of whom worked up our courage to fix three of them! 4. cracked in two places! to get all 4 on the car. Two of this set also broke! I just changed the oil and didn't realize it involved changing the tires. As you might have guessed. They cracked two more when they put the hubcaps back on! So, out of a total of 8 hubcaps, 5 ripped when they were put on the car once or twice! UPDATE UPDATE: Changing a tire resulted in a belt slipping on one tire. were gone again. So I mounted it and took two sets, the rubber in turn has two more cracks, after mounting the new rubber you have my last two photos - again a cracked cap and one of the previous cracked flew off! 4 GOOD!
