I bought these for my Jeep JK which has larger tires with a maximum pressure of 80psi. For outdoor use I use 60-65psi so I needed to be able to see if they were good. It solves this problem, is easy to read and still looks good against the background of the discs. I don't think they're "beautiful," but they're not a particular trait for peppy boys. I've tried them on 3 vehicles to make sure they're being read correctly and so far they seem to be working well. I don't see or notice any leaks on them like I have with other pressure caps. The price is cheap and they work. I will update in about a month.
