If you have a separate set of Nokians, then I think you should go 275/65R18....

 

Too late now..My tires have 3 K on them tops.Size put aside, one of the reasons I went with sT MAXX is their thread depth. Usually tires have 13,15 or 16 mm, these have almost 19 mm , some sources say 18.5 but I will take an extra depth anytime, it matters .
