I was running the Bridgestone Blizzak WS-50 175/65R14 winter tires when I hit a pothole disguised as a puddle last night and blew one of them. It seems like the WS-50s can't be found in my size, so would it be ok to just order two of the WS-60s and have something like two new WS-60s in the front and two older WS-50s in the back? Would we have to throw away one of the WS-50s that's not blown? Seems like a waste 🙁
