These rim locks are really designed for narrow rubber. My trailer has all terrain tires and those locks need to be widened to the last notch and tweaked a bit to lock them. I was disappointed that no two locks had the same keys. This is another key I need to keep with me and I had to draw labels on it so I know which key to use. One of the locks was damaged at the handle/lock plastic sleeve. This doesn't affect the functionality of the lock, but it's not nice to receive damaged units - it wasn't worth the hassle of sending it back, especially when I had to secure a trailer last weekend. If none of these things are important to you, they're fine for the job.
