Back in the day, several of us ran 285/50/18 tires until the market dried up. I think I'd scored the last set of Nitto 404s in that size a few years back.
Didn't think anyone was going to make them anymore, but Continental appears to have just done a run on their CrossContact UHP tires. They're widely available on eBay and listed as new condition. An example: https://www.ebay.com/itm/2-New-Conti...s/362581879929
Anyway, some of us like them, some of you don't, YMMV. They fit fine on stock tires despite what the tire nerds say, and this has been the only size I've ever run since I bought the car in 2008. 51000 failure-free miles and counting.
