I see lots of makes of tires out there that can go on a Cherokee... ranging from the 80 dollar Air Hawk all the way up through 250 dollar Goodyear models. I had new tubes and tires last annual so just need the outside part this time as the tread is worn after nearly 250 hours on the plane. Anyone have any suggestions on what to get? I only use paved strips. I see there are 4 ply and 6 ply versions. Thanks!
