215/65r16 X-Pounce

It looks like you’re referring to a tire size 215/65R16 and possibly something like “X-Piunce” (likely a typo). I’m going to assume you mean a Michelin X-Ice / winter or all-season tire in that size. What 215/65R16 means 215 = tire width in mm 65 = sidewall height (65% of width) R16 = fits a 16-inch rim This is a very common size for SUVs and crossovers.
