Comparing what? Price on GT Radials? Good luck finding another store that carries them, and if they do, they probably source them from Steelcase. Just before I got the Hakka 1s for the old Matrix in December 2002, I was surprised to find Oakville Toyota offered them. I asked how much, and they quoted me $200 more than the quote from Steelcase. I told them I'd just drive to Steelcase in Markham, and Oakville Toyota were surprised I knew about Steelcase, because that was who supplied them with Nokians.
If you're price shopping the GT Radial Champiro WT, you probably have to cmpare it to the Kumho KW19, one of the Hankook tires, or some of the other budget tires being discussed in other threads. They'll all work to a certain degree. It just depends on where your comfort level resides when balancing snow/ice/dry performance, and if you feel the premium brands are worth the extra.
I will say this - I kinda wish I had bought the Hakka 2. When I bought the Champiro, I was commuting 407 and 400 to Newmarket from Mississauga. Now we're moving to Bolton, and I'm travelling the hilly and twisty King Road. The selling point to the Champiro was the H-rating for 400 series highways. Now, the Nokian would probably be the better bet for me. My Champiros are 195/55R15, if anyone is interested

I bought in the summer, because I just got some second hand alloys, switched the Yoko T4 summers to the alloys, and figured I might as well get summers mounted at the same time, saving me some mounting fees and time this fall.
I'm sure the Champiros are a decent tire, or I wouldn't have bought them. tc.xmen, I won't be able to tell you much until the snow flies.
