These tire valve stem caps may look appealing at first but they only look good on the outside... As my tests showed, they are of poor quality and break easily. While they are affordable, it`s not worth the hassle of constantly having to replace them. as for the positives, they do come in a 4-pack, so you can always have extras on hand. However, the cons outweigh the pros, and I would not recommend these universal stem covers for anyone in the market for tire and wheel parts..See full review
