This is just a no brainer for me. I'm not the most safety savvy guy around, hell I push the limit all the time. But on a bike, the number one thing you don't go cheap on is your tires.I'm rollin on all four used tires on my old 62 Beetle. They are full of plugs and I don't sweat it, if one blows up on me, I got 3 more. But on my bike, I don't think I could ever ride the damn thing without wondering if its gonna blow in the next turn. Piece of mind is what your actually paying for.
