The Yoko's are P245/60/R15 in the front and P295/60/R15 in the rear. They are the exact same height & width as the BFG's. I have not autocrossed with them yet but on the street I can tell them have more grip. The ride is quite and I think they are picking up / throwing fewer rocks. The tread pattern looks good and should be good on wet roads. I've had them out on damp and they were fine.
They also fixed a problem I had been living with for 20,000 miles. Durring a long, medium radius turn (On ramps and such) the front would squirm. By that I mean it felt like the power steering was cutting in and out. It was an odd pain in the but, but not a big deal. I figured it was a steering rack or front end design issue, or an outside chance it was the tires. I had pretty much ruled out tires because last fall they were worn down pretty much to the wear bars and I still had the same squirmy feel. No other change to the front end this winter. Just the new Yokohama's and the squirm is GONE.

Go to Tire Racks web site for more info. that's where I did my research. I took there prices and went to a local Yoko tire dealer who matched the price from tire rack. They balanced up well. I've had BFG's that in my opinion needed an awful lot of weights to get them balanced.
There are other threads here that talk about tires.
