I just got a set of 35 lb weights and have a question. When I went to put them on, I noticed that there is no space for the valve stem on my tires to fit. So when the weight is bolted on, it will be pushing the stem over. Is this normal? Am I missing something? Will it damage the seal on my valve stem? The weights are for 12 inch wheels (and that's what I have).
