205/40-17s are 23.5inches in diameter
you can either go with a
205/60-14 = 23.7inches tall
195/60-14 = 23.2inches tall (what I had)
there are several other width/aspect ratio combinations you can go with, but you can;t always find them since some of those combos they do not sell, or are really hard to find.
but the 205/60s and especially the 195/60s are very common. 195/60s are very common. you'll lose a little bit of lift (not much though, like quarter of an inch), but you'll lay harder.
i miss ridin on my balloon tires sometimes. they rode really soft and smooth
