I am having a heck of a time removing the BassCat valve caps that came on my trailer tires. One of the caps I have never been able to get off since I bought the trailer new in 2020 (left rear). And yesterday I was only able to remove 1 (right front) of the 4 (I didn't try the spare) I am hesitant to take pliers to them since I am concerned about tearing the valve stem and really having issues. Once I get them off I plan on replacing with cheap rubber ones, but to do so I need to get them off. Anyone else experience this and if so what did you do to get them off? Thanks.
