This is how a car tire works on a bike

Why do I get the feeling you weren't thinking ice hockey?

But the blade doesn't dig in.

The physics of ice skating has another factor that plays a role in reduction of friction. The formation of a thin layer of water between the surface of solid ice and the edge of the blade.

This water layer is thin, a few thousand molecules or less, and even thinner at lower temperatures.

Silly Californians, stick to roller blades.

It sure digs in when you stop

I have ridden several 100 miles on a rocket III with a Riken Raptor 225/55R16.

It corners fine. As hard as it is for me to wrap my head around what I just said....IT CORNERS FINE.

My problem is when the bike is straight up and down. If the road has a slight crown, the bike "crabs" to me. Feels like it's rolling slightly askew. It feels like I am riding in a constantly changing side draft. I found myself counter steering all over the place and my arms were sore very quickly.

My father in law has 10k on his darkside tire and for him, he's said it's the best thing he's done. He rode it 780 miles one way in a day on it and loves it.

Personally, I think it looks like ass and I don't care for the countersteering....but it's his bike and my Vmax still walks all over it. :-p

Ice skates, snowboards, skis, wakeboards. They all intentionally hydroplane. You wouldn't take a board to the ice rink, or skates to a slope.

No, but skates on a luge run... I could respect that.

Car tires have more siping than motorcycle tires- which means less chance of hydroplaning. They just have more space and more tread which gives better water shedding ability. I've heard of motorcycle touring tires going to 15,000-20,000 miles, when the equivalent hard car tires will run to 50,000 miles. While motorcycle tires have a hard time dealing with 600+ pounds each, car tires frequently deal with greater than that. The tires in that video also have a lot more radius between the sidewall and tread than most.

On a bike that can lean past 25 degrees, handling would definitely go to shit. On a wing or a bagger... Well, I gues if you can adjust to lugging 1,200 pounds around, you can adjust to muscling over a square tire too... From that thread, it sounds like a LOT of shit to adjust to. NO THANKS. Paying for tires is part of the game.

heh yeah my pilot sports started the crabbing around 9k

I think you guys get my point. When you install snow tires, buying thinner ones helps them dig in even better. It's the same principle with rain. Wider tires don't do as well, all other things equal......you can ask Tire Rack for proof.
