by split rim do you mean a two piece rim?

Other than renting a car, my only sugggestion would be for you to buy a winter set of wheels in a smaller size and run Blizzaks so you can spare the winter abuse on your newly refurbished wheels. That's what I do, I use my factory 18" Carreras on sticky summer rubber and when the temps dip to freezing I get out a set of 997 Turbo replica wheels on full winter rubber. That way I don't have to deal with the hassle of lugging tires to the tire shop for twice a year mounting. Winters are too severe here to consider all season tires without a back up vehicle. And all season tires nowhere near as good as my summer tires.

I'd check the classified section of Rennlist and the Pelican forums. Pleny of your warm-beer drinking blokes on there.
