been using theses on my last 2 archers always steady no sway even in cross wind landings the 6 ply keeps the plane heading right where you want it to go. very happy worth the extra $. I fly about 130 hrs per year and never worry about my tires Been getting about 3 years from the tires
I purchased part#06-05400-3 Goodyear Flight Custom III 600-6 6Ply and Part#06-01373 Michelin Inner Tubes 15x6.0-6 STR for my Bellanca Super Viking and they work great. You can get cheaper and you can use recaps but these tires last the longest.
