I have two Chinese quads. I run them thru the exact same conditions. The one with 4 ply tires has many small punctures in all the tires. Seems the rubber is so soft small twigs and branches are poking holes everywhere leaving tiny branches pieces in the tires. While the other has 2 ply tires not even one hole. The 4 ply with the holes I purchased new not too long a go. What gives? Is it the Nylon? Can some one recommend me a set of tires which can perform as well as the 2 ply ones. I have seen these 6 ply but need to be sure they will hold up. Here are some pics of the 2ply, 4ply and the ones I have been thinking about. Ty
