A set of four, brand-new Pirelli Scorpion Winter XL tires suitable for Model X 20" factory wheels: two 265/45R-20 and two 275/45R-20. I bought these last winter expecting to put them on my Sig X for the rest of the snow season, but we didn't take delivery of the X until the end of April so they've never been mounted. Asking $1000 for the set. North Denver metro: cash and carry preferred. If shipping is required it will be at buyer's expense.
