Tire technical websites?
 

Anyone know of a good website that deals with the technical side of tires? I'm not talking about "Brand X has the best winter traction!!!!" websites, but somewhere unbiased that explains the different compounds, sipes, the technical side of tread design, and so on.

Thanks...

If you comb through the links in my tire width/pressure posts, you'll find a few sites that also discuss the things you're considering. I don't remember which ones.

Also, I've posted about a couple books in PDF and dead-tree format that have some of that info in them.
