I was doing some high speed laps around a large, smooth parking lot with the 3s lipo in my RC18t(6800kv mamba) when I had a major tire failure......................................
I got on her a little too hard and blew the back tire right out.(followed by an ugly tumble)
I'm glad I only paid $1 for the set of wheels/tires.
They grip well but you might have some major tread separation at extreme speeds.
