Great prices! It's interesting that only one size -- 205/55/R16 -- is available for 16" wheels. Smaller wheels must be becoming a thing of the past very quickly.
My Nokian Hakka 7 winter tires are XL marked for load. I don't find them awful stiff but then again, I don't expect much comfort out of 1) winter tires in general and 2) 2014 Mazda5 van.
