For 20" OEM wheels, the same guide recommends the Pirelli Scorpion in the 255/60/20, however, it also recommends the Nokian Hakkapelliitta R3 SUV in 275/55/20. As long as you have OEM wheels, should be good to go with 275/55/20. This is what I am likely to do after securing some 20" wheels. Good luck!
