I absolutely love 15-17s all around on my fix gear wheels and same but 14-16 right rear on the geared wheels. My Mooney wore a set of the latter with GP4s in the 90s. Those wheels went 17,000 miles with a couple of tweaks of the spokes. Rear rim failed when I bunny hopped a crack and missed. (Brakes and super abrasive Pacific NW lava dust. No sidewall left.) Had to bump on home with an inch deep indent. The sewup didn't care.
