Yes, the 225 would be wider. The first # is the tread width in millimeters, the next is the ratio (%-age) of sidewall profile to width, and the third is rim diameter in inches. For example, a 225/70/16 would be a 225mm wide tire with a height (sidewall) of 70% of 225mm (in this case 157.5mm or 6.2"), and an I.D. of 16" (i.e. 16" rim). Hope that helps.
