16s are no picnic, either, unless you're driving a truck. When I bought my rear tires, I had chosen matching-tread front rubber in a 235/60R-16 size. A week after I got the rears, the front size went on backorder. That became national backorder, progressed to intergalactic backorder, and finally my money was refunded because that tire had been discontinued. I still don't have front rubber. I can get the size, but not the same manufacturer or tread pattern.
