I went shopping for 225 radials a number of years ago and ended up with 215's. The 225 size was no longer in the Michelin catalog. The 14" wheel size is the problem as the 225-15R was and is a popular size (Buick Roadmaster, RWD Cadillacs and Chevy Caprice until they went out of production). I do not know if the availability situation is the same if a search is made for any other brand but it would make sense if the size did not show up anywhere else. BTW, the 215's have been just fine on the New Yorker although the 225 size would definately look better. Having been down the problem tire route so many times, I prefer to stay with what works every time for me and use Michelins whenever possible. Warren Anderson Sedona,AZ
