Hi Frogbox,
I did find a set steel of black 18" wheels that permitted me to reuse my 18" Michelin X-Ice tires. They are hubcentric with a 45mm offset but have enough back spacing for the wheel to clear the larger later model brake calipers. His price ($105/wheel) was less than we could buy them for from the same supplier, so he must purchase in huge volumes. The store is Wheel Pros in Calgary and owned by a guy who calls himself "Jimmy the Wheel" . :-) Before he hands the wheels over, he puts every wheel on this balancer to check for balance and straightness. His knave even loaded them into the back of the car for me. I got them on just in time for yet more snow in Calgary.
It was interesting driving the car on proper winter tires after mucking around in the snow on the Kumhos, which are not a bad 3 season tires. The car turns, stops, and hooks up 100% better.
People, there is no such thing as an all-season tire. Buy yourselves dedicated winter tires, the price is likely less than your insurance deductible. With proper inflation and alignment, you can likely get 3 or 4 winters out of them.
Cheers,
Mike
