We have Nokian Hakkapeliitta R's on our TC. They have outstanding snow and ice traction, low rolling resistance, excellent tread wear for a snow, but are expensive. Buying cheap tires never made sense to me.
They have "SUV" grade tires with higher load ratings, but those aren't available in 15".
The 205/65R15 are rated XL (extra load) and have a load rating of 99R. 99 = 1,709 lbs/tire.
For comparison, a Michelin X-Ice Xi2 has a load rating of 94T - 1,477 lbs. Probably still OK for a vehicle with a GWR of 5,005.
