Tire for Fish N Mate Jr

I have the Fish-N-Mate Jr cart, and I have the bubble tires for sand, and now I have the tread tires for pier and everywhere else. They seem sturdy. I haven't used them yet, but I think they're going to make the perfect cart for either beach or pier fishing so long as I change the tires accordingly. The orange beach tires scare me a bit, as they're fairly thin...not paper thin...adequate, but thin. I think with a little situational awareness and care they will last a long time. The pier tires are MUCH thicker and more like an actual tire. They didn't break the bank either, so I think it's a good thing for people to consider having both if you want to do pier and beach fishing. As far as durability there's no comparison between the two.
