I finally got off my ass and changed one tire. I'll do the other one tomorrow. These Hook Worms sure are little. It's pretty hard for me to believe they'll be able to out corner the thick Bricks from looking at them. Just the sheer amount of rubber the Thick Bricks lay down on the road says there's probably no way to beat them. I probably won't care though. I'm only changing them for cosmetic reasons anyway. I think acceleration will improve a little from the gearing reduction.
The Kenda Downhill tubes I bought are super thick. Easily the thickest tubes I've ever used. I've been whacking rubber off an old truck inner tube in my shop that's not nearly as thick these. I also reused my Mr Tuffy tube liners, so hopefully I'll be as flat resistant as before, knock on wood. I haven't had a flat in over 4000 miles now.
I may have to do a little work on my fenders now because they're going to be standing up so high off the tires.
Eventually I'll post some pics.
